Two areas covering the whole territory of Serbia are treated: a complex terrain area (CTA) and a flat terrain area (FTA). Our research shows that the highest hail frequencies were found in the southwestern mountainous part of the country in the warm season. In the cold season, the area of maximum hail frequency lies in the region of the Sava and the Danube rivers. During the warm season, the highest hail frequencies are recorded in May and June and the smallest in August and September. This spatial pattern is influenced by the passages of the prevailing fronts, surface air temperatures and the convection enhancement by the mountains during the year. The trends of mean hail frequency are negative, except for the FTA in the dry season (August–September) and the cold season, in which nonparametric methods do not show any trends. The highest hail frequency area does not show any trend in the warm season, but interdecadal variability is significant. In general, the CTA has a greater mean hail frequency for all treated seasons. In contrast, the FTA has a greater maximum of mean hail frequency per station in the dry (August–September) and cold seasons. Although very small, the territory of Serbia also shows other peculiarities. In the last decade, the FTA has shown a strong positive trend of mean hail frequency as opposed to the CTA. This is due to the fact that the ridge of the Azores high extended over the CTA more frequently than before 2000.}, author = {{\'{C}}uri{\'{c}}, Mladjen and Janc, Dejan}, doi = {10.1002/joc.4554}, issn = {08998418}, journal = {International Journal of Climatology}, keywords = {hail frequency,interdecadal variability,spatial pattern,trend characteristics}, month = {jul}, number = {9}, pages = {3270--3279}, title = {{Hail climatology in Serbia}}, url = {https://rmets.onlinelibrary.wiley.com/doi/abs/10.1002/joc.4554 http://doi.wiley.com/10.1002/joc.4554}, volume = {36}, year = {2016} } @article{Zebre2021a, abstract = {Mountain glaciers are key indicators of climate change.

Most of the existing drought projections over Southern Africa are based on precipitation alone, neglecting the influence of potential evapotranspiration (PET). The present study shows that inclusion of PET may alter the magnitude and robustness of the drought projections. The study used two drought indices to project potential impacts of global warming on Southern African droughts, focusing on four major river basins. One of the drought indices (SPEI: Standardized Precipitation Evapotranspiration Index) is obtained from climate water balance (i.e. precipitation minus potential evapotranspiration) while the other (SPI: Standardized Precipitation Index) is calculated from precipitation alone. For the projections, we analyzed multi-model regional climate simulations from the Coordinated Regional Climate Downscaling Experiment (CORDEX) at four specific global warming levels (GWLs) (i.e., 1.5 °C, 2.0 °C, 2.5 °C, and 3.0 °C) above the pre-industrial level and used the self-organizing maps to classify the drought projections into groups based on their similarities. Our results show that the CORDEX simulations give a realistic representation of all the necessary climate variables for quantifying droughts over Southern Africa. The simulations project a robust increase in SPEI drought intensity and frequency over Southern Africa and indicate that the magnitude of the projection increases with increasing GWLs, especially over the various river basins. In contrast, they project a non-significant change in SPI droughts at all the GWLs. The majority of the simulations clearly distinguish between the projected SPEI and SPI drought patterns, and the distinction becomes clearer with increasing GWLs. Hence, using precipitation alone for drought projection over Southern Africa may underestimate the magnitude and robustness of the projections.

Australia's hottest and driest year on record, 2019, was characterised by exceptionally dry fuel loads that primed the landscape to burn when exposed to dangerous fire weather and ignition. The combination of climate variability and long-term climate trends generated the climate extremes experienced in 2019, and the compounding effects of two or more modes of climate variability in their fire-promoting phases (as occurred in 2019) has historically increased the chances of large forest fires occurring in southeast Australia. Palaeoclimate evidence also demonstrates that fire-promoting phases of tropical Pacific and Indian ocean variability are now unusually frequent compared with natural variability in pre-industrial times. Indicators of forest fire danger in southeast Australia have already emerged outside of the range of historical experience, suggesting that projections made more than a decade ago that increases in climate-driven fire risk would be detectable by 2020, have indeed eventuated.

However, knowledge about coastal erosion, by the local people, and how far the shoreline has migrated inland over time is high in the coastal communities in Accra.

It was revealed that about 79{\%} of the shoreline is eroding, while the remaining 21{\%} is either stabilised or accreting. It emerged, from semi-structured interviews with inhabitants in the Accra coastal communities, that an average of about 30 m of coastal lands are perceived to have been lost to erosion for a period of about 20 years. This translates to a historic rate of change of about 1.5 m/year, which corroborates the results of the scientific study.

In this analysis, we scaled down to the district-level weekly scale (which is used for in-year response to emerging epidemics), and used wavelet and phase analysis methods to define and compare the time-varying periodicities of meningitis, climate and dust in Niger. We mostly focused on detecting time-lags between the signals that were consistent across districts.

The gauge-based gridded precipitation and temperature data with a spatial resolution of 0.5° is used for the reconstruction of droughts using standardized precipitation evapotranspiration index (SPEI).

Temperature is found as the dominating factor for defining droughts in arid and semi-arid regions while the precipitation in WD influenced region. An increase in temperature in the range of 0.001 to 0.025 °C per year and almost no change in precipitation have caused decreases in Rabi SPEI in the range of −0.011 to −0.025 per year in the arid region.

The UNESCO aridity index was used to estimate aridity at each grid point for all the years between 1901 and 2016. The temporal changes in aridity and its associations with precipitation and PET are evaluated by implementing a moving window of 50 years of data with an 11-year interval. The modified Mann-Kendall (MMK) trend test is applied to estimate unidirectional change by eliminating the effect of natural variability of climate, and Pettitt's test is used to detect year of change in aridity. The results revealed that the climate over 60{\%} of Pakistan (mainly in southern parts) is arid. The spatial patterns of aridity trends show a strong influence of the changes in precipitation on the aridity trend. The increasing trend in aridity (drier) is noticed in the southwest, where precipitation is low during Kharif, while there is a decreasing trend (wetter) in the Rabi season in the region which receives high precipitation due to western disturbances. The annual and Kharif aridity is found to decrease (wetter) at a rate of 0.0001 to 0.0002 per year in the northeast, while Kharif and Rabi aridity are found to increase (drier) at some locations in the south at a rate of -0.0019 to -0.0001 per year.

For future changes (up to the year 2100), the same parameters were extracted from an ensemble of 12 downscaled regional climate models (RCM) of the Coordinated Regional Climate Downscaling Experiment (CORDEX)-South Asia simulations for low and high emission scenarios (Representative Concentration Pathways 4.5 and 8.5). In the past, the climatic changes were mainly characterized by a mean temperature increase above global level of 1.8 °C from 1950 to 2010; uncertainty with regard to reanalyzed rainfall data limited a thorough analysis of past changes. Climate models projected the temperature trend to accelerate in the future, depending strongly on the global carbon emissions (2006–2050 Representative Concentration Pathways 4.5/8.5: 1.7/2.3 °C; 2006–2099: 2.7/6.4 °C, respectively). Despite the high uncertainty with regard to precipitation projections, it became apparent that the increasing evapotranspiration is likely to exacerbate Afghanistan's already existing water stress, including a very strong increase of frequency and magnitude of heat waves. Overall, the results show that in addition to the already extensive deficiency in adaptation to current climate conditions, the situation will be aggravated in the future, particularly in regard to water management and agriculture. Thus, the results of this study underline the importance of adequate adaptation to climate change in Afghanistan.

This study aims to compare impacts of climate change on streamflow in four large representative African river basins: the Niger, the Upper Blue Nile, the Oubangui and the Limpopo. We set up the eco-hydrological model SWIM (Soil and Water Integrated Model) for all four basins individually. The validation of the models for four basins shows results from adequate to very good, depending on the quality and availability of input and calibration data. For the climate impact assessment, we drive the model with outputs of five bias corrected Earth system models of Coupled Model Intercomparison Project Phase 5 (CMIP5) for the representative concentration pathways (RCPs) 2.6 and 8.5. This climate input is put into the context of climate trends of the whole African continent and compared to a CMIP5 ensemble of 19 models in order to test their representativeness. Subsequently, we compare the trends in mean discharges, seasonality and hydrological extremes in the 21st century. The uncertainty of results for all basins is high. Still, climate change impact is clearly visible for mean discharges but also for extremes in high and low flows. The uncertainty of the projections is the lowest in the Upper Blue Nile, where an increase in streamflow is most likely. In the Niger and the Limpopo basins, the magnitude of trends in both directions is high and has a wide range of uncertainty. In the Oubangui, impacts are the least significant. Our results confirm partly the findings of previous continental impact analyses for Africa. However, contradictory to these studies we find a tendency for increased streamflows in three of the four basins (not for the Oubangui). Guided by these results, we argue for attention to the possible risks of increasing high flows in the face of the dominant water scarcity in Africa.

Model runs for future flood risks were conducted with an ensemble of 18 climate models, 13 of them dynamically downscaled from the CORDEX Africa project and five statistically downscaled Earth System Models. Two climate and two land use change scenarios were used to cover a broad range of potential developments in the region. Two flood indicators (annual 90th percentile and the 20-year return flood) were used to assess the future flood risk for the Upper, Middle and Lower Niger as well as the Benue. The modeling results generally show increases of flood magnitudes when comparing a scenario period in the near future (2021-2050) with a base period (1976-2005). Land use effects are more uncertain, but trends and relative changes for the different catchments of the NRB seem robust. The dry areas of the Sahelian and Sudanian regions of the basin show a particularly high sensitivity to climatic and land use changes, with an alarming increase of flood magnitudes in parts. A scenario with continuing transformation of natural vegetation into agricultural land and urbanization intensifies the flood risk in all parts of the NRB, while a "regreening" scenario can reduce flood magnitudes to some extent.

Three different types of weighting namely equal weighting, independence based weighting and performance based weighting have been employed to assess the uncertainties of GCM projection over different zones. It has been found that ensemble with performance based weighting has produced smaller inter-model uncertainty but the patterns of temporal evolution of uncertainties have been quite irregular compared to other two ensembles. On the other hand, it has been noticed that bias correction using quantile mapping can effectively reduce the range of uncertainty in a systematic way.

However, the limited research on reef islands in the western Pacific indicates the majority of shoreline changes and inundation to date result from extreme events, seawalls and inappropriate development rather than sea-level rise alone. Here, we present the first analysis of coastal dynamics from a sea-level rise hotspot in the Solomon Islands. Using time series aerial and satellite imagery from 1947 to 2014 of 33 islands, along with historical insight from local knowledge, we have identified five vegetated reef islands that have vanished over this time period and a further six islands experiencing severe shoreline recession. Shoreline recession at two sites has destroyed villages that have existed since at least 1935, leading to community relocations. Rates of shoreline recession are substantially higher in areas exposed to high wave energy, indicating a synergistic interaction between sea-level rise and waves.

We calculate 24 indices representing extremes of temperature and precipitation from 1911 to 2010 over Australia and show that there have been significant observed trends in temperature extremes associated with warming while there have been few significant observed trends in precipitation extremes. We compare the observed indices calculated from two mostly independent datasets with 22 CMIP5 models to determine how well global climate models are able to simulate observed climatologies, variability and trends. We find that generally temperature extremes are reasonably well simulated (climatology, variability and trend patterns) although the models tend to overestimate minimum temperature extremes and underestimate maximum temperature extremes. Some models stand out as being outliers and we exclude one model (INMCM4) entirely from the multi-model analysis as it simulates unrealistic minimum temperature extremes over the historical period. There is more spread between models for precipitation than temperature extremes but in most cases the observations sit within the model spread. Exceptions are consecutive wet days (CWD) where nearly all models overestimate the actual number of annual wet days and simple daily intensity (SDII) and one day precipitation maxima (Rx1day) where the models tend to underestimate precipitation intensity. However, some of these differences likely lie in observational uncertainty. Most models including the multi-model mean indicate that precipitation intensity has increased over the last century but the two observational datasets analysed disagree on the sign of change of precipitation intensity, one of them indicating a significant decrease. We use the CMIP5 simulations for two future Representative Concentration Pathway (RCP) scenarios (RCP4.5 and RCP8.5) to project changes in temperature and precipitation extremes across Australia. By the end of the century the number of cold temperature extremes substantially reduces and the number of warm temperature extremes substantially increases; changes scaling relative to the strength of emissions scenario. Changes in temperature extremes are often greatest in the tropics. While the results for precipitation extremes are less marked, simulations for the end of the century compared to present day indicate more periods of dryness while the most intense precipitation extremes increase substantially, with a separation becoming clear between emissions scenarios.}, author = {Alexander, Lisa V. and Arblaster, Julie M.}, doi = {10.1016/j.wace.2017.02.001}, issn = {22120947}, journal = {Weather and Climate Extremes}, keywords = {Future projections,Model evaluation,Scaling issues,Trends}, month = {mar}, pages = {34--56}, publisher = {Elsevier}, title = {{Historical and projected trends in temperature and precipitation extremes in Australia in observations and CMIP5}}, url = {http://www.sciencedirect.com/science/article/pii/S2212094716300780 https://linkinghub.elsevier.com/retrieve/pii/S2212094716300780}, volume = {15}, year = {2017} } @article{Alfieri2015, abstract = {At the current rate of global warming, the target of limiting it within 2 degrees by the end of the century seems more and more unrealistic.

Phenomena associated with severe thunderstorms such as large hail (greater than 2 cm), damaging winds (greater than 90 kmh−1), and tornadoes pose a global threat, and have been documented on every continent except Antarctica. Limitations of observational records for assessing past trends have driven a variety of approaches to not only characterize the past occurrence but provide a baseline against which future projections can be interpreted. These proxy methods have included using environments or conditions favorable to the development of thunderstorms and directly simulating storm updrafts using dynamic downscaling. Both methodologies have demonstrated pronounced changes to the frequency of days producing severe thunderstorms. Major impacts of a strongly warmed climate include a general increase in the length of the season in both the fall and spring associated with increased thermal instability and increased frequency of severe days by the late 21st century. While earlier studies noted changes to vertical wind shear decreasing frequency, recent studies have illustrated that this change appears not to coincide with days which are unstable. Questions remain as to whether the likelihood of storm initiation decreases, whether all storms which now produce severe weather will maintain their physical structure in a warmer world, and how these changes to storm frequency and or intensity may manifest for each of the threats posed by tornadoes, hail, and damaging winds.

Rockfall observations from the Swiss Alps, Mont Blanc Massif, and Southern Alps of New Zealand, are combined with climate analyses based on the nearest available long-term records.

In the same region, an unusually high occurrence of extremely warm days occurring in the week leading up to rockfalls has been observed over recent decades, with 14 out of 24 rockfalls preceded by one or more extremely warm days. At the neighboring Mont Blanc Massif, based on only two years of observations, few rockfalls can be linked to extremely warm temperatures, although an early and extremely warm onset of seasonal thawing in spring 2007 may have contributed to the large number of rockfalls observed that same summer.

In the historical period, the median of the CMIP6 model ensemble systematically underestimates the annual mean temperature for all the South Asian countries, while a mixed behavior is shown in the case of precipitation. In the future climate, the CMIP6 models display higher sensitivity to greenhouse gas emissions over South Asia compared with the CMIP5 models. The multimodel ensemble from 27 CMIP6 models projects a continuous increase in the annual mean temperature over South Asia during the twenty-first century under three future scenarios. The projected temperature shows a large increase (over 6 °C under SSP5-8.5 scenario) over the northwestern parts of South Asia, comprising the complex Karakorum and Himalayan mountain ranges. Any large increase in the mean temperature over this region will most likely result in a faster rate of glacier melting. By the end of the twenty-first century, the annual mean temperature (uncertainty range) over South Asia is projected to increase by 1.2 (0.7–2.1) °C, 2.1 (1.5–3.3) °C, and 4.3 (3.2–6.6) °C under the SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios, respectively, relative to the present (1995–2014) climate. The warming over South Asia is also continuous on the seasonal time scale. The CMIP6 models projected higher warming in the winter season than in the summer over South Asia, which if verified will have repercussions for snow/ice accumulations as well as winter cropping patterns. The annual mean precipitation is also projected to increase over South Asia during the twenty-first century under all scenarios. The rate of change in the projected annual mean precipitation varies considerably between the South Asian countries.

For rainfall induced landslides, the point consists in determining the effects of the projected changes in the duration and amounts of rainfall that can initiate slope failures. We investigated the relationship between fine-scale climate projections obtained by downscaling and the expected modifications in landslide occurrence in Central Italy. We used rainfall measurements taken by 56 rain gauges in the 9-year period 2003–2011, and the RainFARM technique to generate downscaled synthetic rainfall fields from regional climate model projections for the 14-year calibration period 2002–2015, and for the 40-year projection period 2010–2049. Using a specific algorithm, we extracted a number of rainfall events, i.e. rainfall periods separated by dry periods of no or negligible amount of rain, from the measured and the synthetic rainfall series. Then, we used the selected rainfall events to forcethe Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Model TRIGRS v. 2.1. We analyzed the results in terms of variations (or lack of variations) in the rainfall thresholds for the possible initiation of landslides, in the probability distribution of landslide size (area), and in landslide hazard. Results showed that the downscaled rainfall fields obtained by RainFARM can be used to single out rainfall events, and to force the slope stability model.

We used observations, reanalysis datasets, and high-resolution simulations from the Weather Research and Forecasting (WRF) model to show that irrigation significantly modulates SM and atmospheric aridity in India. The Indo-Gangetic Plain, which is one of the most intensively irrigated regions in the world, experienced significant (P-value = 0.03) cooling (∼0.8 °C) and an increase in solar-induced chlorophyll fluorescence during the crop growing season (November–February). Atmospheric aridity has significantly (P-value = 0.0002) declined (−1.38 kPa) while SM (1.6 m3 m−3) and relative humidity (RH) (2.0{\%}) have increased over the Indo-Gangetic Plain during 1979–2018. We conducted high-resolution simulations using the WRF model to examine the role of irrigation on atmospheric aridity. Irrigation strongly modulates SM drought and atmospheric aridity by increasing latent heat and RH and reducing sensible heat. Our findings have implications as irrigation can influence compound extremes of SM drought and atmospheric aridity.

The study uses data collected from 193 household surveys in 2 communities across 2 districts in the Upper East region of Ghana. The logit regression was performed based on a disaggregated procedure.

Results show that only 50{\%} (n = 121) of the male farmers compared with just 31{\%} (n = 72) of female farmers were willing to pay for climate information. The results from the marginal analysis suggest that access to climate information is influenced by both household and environmental factors. The marginal effects logistic regression shows statistically significant differences in the predictors of access and willingness to pay for climate information based on gender. Findings highlight that the provision of climate information should be designed and tailored to meet the needs of smallholder farmers with different socioeconomic backgrounds to enable farmers manage climate risks and build adaptive capacity.

The results show that the changes in annual maximum daily flows in Sweden oscillate between dry and wet periods but exhibit no significant trend over the past 100 years. Temperature was found to be the strongest climate driver of changes in river high flows, which are related primarily to snowmelt in Sweden. Annual daily high flows may decrease by on average {\&}minus;1{\%} per decade in the future, mainly due to lower peaks from snowmelt in the spring ({\&}minus;2{\%} per decade) as a result of higher temperatures and a shorter snow season. In contrast, autumn flows may increase by {\&}plus;3{\%} per decade due to more intense rainfall. This indicates a shift in flood-generating processes in the future, with greater influence of rain-fed floods. Changes in climate may have a more significant impact on some specific rivers than on the average for the whole country. Our results suggest that the temporal pattern in future daily high flow in some catchments will shift in time, with spring floods in the northern-central part of Sweden occurring about 1 month earlier than today. High flows in the southern part of the country may become more frequent. Moreover, the current boundary between snow-driven floods in northern-central Sweden and rain-driven floods in the south may move toward higher latitudes due to less snow accumulation in the south and at low altitudes.

Changes are compared with natural variability, with a significant change being defined as greater than the standard deviation of the hydrological indicator in the absence of climate change. Under an SRES (Special Report on Emissions Scenarios) A1b emissions scenario, substantial proportions of the land surface (excluding Greenland and Antarctica) would experience significant changes in hydrological behaviour by 2050; under one climate model scenario (Hadley Centre HadCM3), average annual runoff increases significantly over 47{\%} of the land surface and decreases over 36{\%}; only 17{\%} therefore sees no significant change. There is considerable variability between regions, depending largely on projected changes in precipitation. Uncertainty in projected river flow regimes is dominated by variation in the spatial patterns of climate change between climate models (hydrological model uncertainty is not included). There is, however, a strong degree of consistency in the overall magnitude and direction of change. More than two-thirds of climate models project a significant increase in average annual runoff across almost a quarter of the land surface, and a significant decrease over 14{\%}, with considerably higher degrees of consistency in some regions. Most climate models project increases in runoff in Canada and high-latitude eastern Europe and Siberia, and decreases in runoff in central Europe, around the Mediterranean, the Mashriq, central America and Brasil. There is some evidence that project change in runoff at the regional scale is not linear with change in global average temperature change.

Uncertainty in the regional pattern of climate change is characterised by CMIP5 climate model projections. The analysis adopts a novel approach using relationships between level of warming and impact to rapidly estimate impacts under any climate forcing. The projections provided here can be used to inform assessments of the implications of climate change. At the global scale all the consequences of climate change considered here are adverse, with large increases under the highest rates of warming. Under the highest forcing the global average annual chance of a major heatwave increases from 5{\%} now to 97{\%} in 2100, the average proportion of time in drought increases from 7{\%} to 27{\%}, and the average chance of the current 50 year flood increases from 2{\%} to 7{\%}. The socio-economic impacts of these climate changes are determined by socio-economic scenario. There is variability in impact across regions, reflecting variability in projected changes in precipitation and temperature. The range in the estimated impacts can be large, due to uncertainty in future emissions and future socio-economic conditions and scientific uncertainty in how climate changes in response to future emissions. For the temperature-based indicators, the largest source of scientific uncertainty is in the estimated magnitude of equilibrium climate sensitivity, but for the indicators determined by precipitation the largest source is in the estimated spatial and seasonal pattern of changes in precipitation.

The full impact of arctic winters may be best manifest by freshwater ice growth and the extent to which abundant shallow ACP lakes freeze solid with bedfast ice by the end of winter. For example, winter conditions of 2016-17 produced record low extents of bedfast ice across the ACP. In addition to high air temperatures, the causes varied from deep snow accumulation on the Barrow Peninsula to high late season rainfall and lake levels farther east on the ACP. In contrast, the previous winter of 2015-16 was also warm, but low snowpack and high winds caused relatively thick lake ice to develop and corresponding high extents of bedfast ice on the ACP. This recent comparison of extreme variation in lake ice responses between two adjacent regions and years in the context of long-term climate and ice records highlights the complexity associated with weather conditions and climate change in the Arctic.

Studies have shown that extreme heat has a large impact on mortality and morbidity, with a large relative increase for respiratory diseases. Expected increases in mean temperature and the number of extreme heat events over the coming decades due to climate change raise questions about the possible health impacts. We assess the number of heat-related respiratory hospital admissions in a future with a different climate. DESIGN A Europe-wide health impact assessment. SETTING An assessment for each of the EU27 countries. METHODS Heat-related hospital admissions under a changing climate are projected using multicity epidemiological exposure-response relationships applied to gridded population data and country-specific baseline respiratory hospital admission rates. Times-series of temperatures are simulated with a regional climate model based on four global climate models, under two greenhouse gas emission scenarios. RESULTS Between a reference period (1981-2010) and a future period (2021-2050), the total number of respiratory hospital admissions attributed to heat is projected to be larger in southern Europe, with three times more heat attributed respiratory hospital admissions in the future period. The smallest change was estimated in Eastern Europe with about a twofold increase. For all of Europe, the number of heat-related respiratory hospital admissions is projected to be 26 000 annually in the future period compared with 11 000 in the reference period.

Here we quantify SLR driven potential shoreline retreat and consequent coastal land loss in Europe during the twenty-first century using different combinations of geophysical datasets for (a) the location and spatial extent of sandy beaches and (b) their nearshore slopes. Using data-based spatially-varying nearshore slope data, a European averaged SLR driven median shoreline retreat of 97 m (54 m) is projected under RCP 8.5 (4.5) by year 2100, relative to the baseline year 2010. This retreat would translate to 2,500 km2 (1,400 km2) of coastal land loss (in the absence of ambient shoreline changes). A variance-based global sensitivity analysis indicates that the uncertainty associated with the choice of geophysical datasets can contribute up to 45{\%} (26{\%}) of the variance in coastal land loss projections for Europe by 2050 (2100).

These maps are usually built up from wind speeds recorded at a network of weather stations.

This has favored agriculture yields and the extension of crop lands into semiarid regions, but this increase also came with more frequent heavy rainfalls and consequent flooding of rural and urban areas. Since the early 1970s, the main rivers of the Plata Basin have increased their mean flows, but this was attributable not only to increased precipitation, but also to land use changes. In contrast, over the Andes Mountains, reduced rainfall and increased temperature has led to glaciers receding and reduced river flows. Climate projections for the first half of this century maintain observed trends and raise additional concerns that in most cases can be dealt with timely adaptation policies. However, by the end of this century, under an extreme emissions scenario, the projected warming reaches 3.5°C in the north of the country with respect to present-day conditions. There is insufficient knowledge to assume that this warming would not create severe damages to the people and the economy of Argentina.

This was undertaken by determining: (a) the contribution of model and scenario uncertainty and natural variability to the total variance of these future projections, and (b) the timing of climate signal emergence from the background noise of natural climate variability. We examined future projections of mean temperature, precipitation and summer climate moisture index (CMI). In this region, natural climate variability plays an important role in future uncertainty until the end of this century, particularly for precipitation and to a lesser extent, summer CMI. Model uncertainty also contributes to total uncertainty for these variables throughout this century, while scenario uncertainty becomes more important towards the end of the century. For the region as a whole, significant climate change (i.e., signal/noise {\textgreater}2) occurs earliest for summer mean temperature, with median time of emergence around 2035 for the RCP8.5 radiative forcing scenario. Although the median precipitation signal emerges from the noise (i.e., signal/noise {\textgreater}1) around the 2070s in winter and the 2080s in spring, significant values do not occur in any season for this variable before 2100. For summer CMI, the median time of emergence for significant change is around 2085. At the grid scale, signal-to-noise ratios are significant for all seasons for mean surface air temperature, with earliest times of emergence occurring in summer. In contrast, the summer precipitation signal is not significant this century; for summer CMI, significant values are obtained in the eastern half of the region, occurring from about 2065 onwards.

The objective of the present work is to compare the projections of surface solar radiation (SSR) simulated by four regional climate models (CCLM, RCA4, WRF, ALADIN) with the respective fields of their ten driving CMIP5 global climate models. First the annual and seasonal SSR changes are examined in the regional and in the global climate models based on the RCP8.5 emission scenarios. The results show significant discrepancies between the projected SSR, the multi-model mean of RCMs indicates a decrease in SSR of −0.60 W/m2per decade over Europe, while the multi-model mean of the associated GCMs used to drive the RCMs gives an increase in SSR of +0.39 W/m2per decade for the period of 2006–2100 over Europe. At seasonal scale the largest differences appear in spring and summer. The different signs of SSR projected changes can be interpreted as the consequence of the different behavior of cloud cover in global and regional climate models. Cloudiness shows a significant decline in GCMs with −0.24{\%} per decade which explains the extra income in SSR, while in case of the regional models no significant changes in cloudiness can be detected. The reduction of SSR in RCMs can be attributed to increasing atmospheric absorption in line with the increase of water vapor content. Both global and regional models overestimate SSR in absolute terms as compared to surface observations, in line with an underestimation of cloud cover. Regional models further have difficulties to adequately reproduce the observed trends in SSR over the past decades.}, author = {Bart{\'{o}}k, Blanka and Wild, Martin and Folini, Doris and L{\"{u}}thi, Daniel and Kotlarski, Sven and Sch{\"{a}}r, Christoph and Vautard, Robert and Jerez, Sonia and Imecs, Zolt{\'{a}}n}, doi = {10.1007/s00382-016-3471-2}, issn = {0930-7575}, journal = {Climate Dynamics}, month = {oct}, number = {7-8}, pages = {2665--2683}, title = {{Projected changes in surface solar radiation in CMIP5 global climate models and in EURO-CORDEX regional climate models for Europe}}, url = {http://link.springer.com/10.1007/s00382-016-3471-2}, volume = {49}, year = {2017} } @article{Bartiko2019, abstract = {Brazil has some of the largest rivers in the world and has the second greatest flood loss potential among the emergent countries.

These long‐term downward trends are likely related to a statistically significant downward shift around 1943 detected (using the nonparametric Pettitt test) in index records of streamflow and base flow. The downward shift corresponds to a decrease of 22{\%} in median streamflow and a decrease of 23{\%} in median base flow between the periods 1913–1943 and 1943–2008. The shift coincides with other local and regional factors, including a change from a positive to a negative phase in the Pacific Decadal Oscillation, shifts in the direction of the trade winds over Hawai‘i, and a reforestation programme. The detected shift and long‐term trends reflect region‐wide changes in climatic and land‐cover factors. A weak pattern of downward trends in base flows during the period 1943–2008 may indicate a continued decrease in base flows after the 1943 shift. Downward trends were detected more commonly in base‐flow records than in high‐streamflow, peak‐flow, and rainfall records.

While a broad variety of maize simulation models exist, it is not known whether different models diverge on grain yield responses to changes in climatic factors, or whether they agree in their general trends related to phenology, growth, and yield. With the goal of analyzing the sensitivity of simulated yields to changes in temperature and atmospheric carbon dioxide concentrations [CO2], we present the largest maize crop model intercomparison to date, including 23 different models. These models were evaluated for four locations representing a wide range of maize production conditions in the world: Lusignan (France), Ames (USA), Rio Verde (Brazil) and Morogoro (Tanzania). While individual models differed considerably in absolute yield simulation at the four sites, an ensemble of a minimum number of models was able to simulate absolute yields accurately at the four sites even with low data for calibration, thus suggesting that using an ensemble of models has merit. Temperature increase had strong negative influence on modeled yield response of roughly -0.5 Mg ha-1per °C. Doubling [CO2] from 360 to 720 $\mu$mol mol-1increased grain yield by 7.5{\%} on average across models and the sites. That would therefore make temperature the main factor altering maize yields at the end of this century. Furthermore, there was a large uncertainty in the yield response to [CO2] among models. Model responses to temperature and [CO2] did not differ whether models were simulated with low calibration information or, simulated with high level of calibration information. {\textcopyright} 2014 John Wiley.}, author = {Bassu, Simona and Brisson, Nadine and Durand, Jean-Louis and Boote, Kenneth and Lizaso, Jon and Jones, James W. and Rosenzweig, Cynthia and Ruane, Alex C. and Adam, Myriam and Baron, Christian and Basso, Bruno and Biernath, Christian and Boogaard, Hendrik and Conijn, Sjaak and Corbeels, Marc and Deryng, Delphine and {De Sanctis}, Giacomo and Gayler, Sebastian and Grassini, Patricio and Hatfield, Jerry and Hoek, Steven and Izaurralde, Cesar and Jongschaap, Raymond and Kemanian, Armen R. and Kersebaum, K.

Any changes in extratropical cyclone activity over Eurasia in the future may have a critical impact on winter agriculture and the economies of affected communities. However, potential future changes in regional storm activity over Eurasia have not been studied in detail. Therefore, in this study, we investigate anticipated changes in extratropical storm activity by the end of the century through a detailed examination of the historical and future emission scenarios from six different models from CMIP5. A statistical analysis of different parameters of storm activity using a storm identification and tracking algorithm reveals a decrease in the number of storms over mid-latitude regions. However, intense storms with longer duration are projected over high latitude Eurasia. A further examination of the physical mechanism for these changes reveals that a decrease in the meridional temperature gradient and a weakening of the vertical wind shear over the mid-latitudes are responsible for these changes in storm activity.}, annote = {doi: 10.1002/2017EF000670}, author = {Basu, Soumik and Zhang, Xiangdong and Wang, Zhaomin}, doi = {10.1002/2017EF000670}, issn = {2328-4277}, journal = {Earth's Future}, keywords = {CMIP5,Eurasian winter storms,Extratropical cyclones,Future climate variability}, month = {jan}, number = {1}, pages = {61--70}, publisher = {John Wiley {\&} Sons, Ltd}, title = {{Eurasian Winter Storm Activity at the End of the Century: A CMIP5 Multi-model Ensemble Projection}}, url = {https://doi.org/10.1002/2017EF000670}, volume = {6}, year = {2018} } @article{Baztan2020, abstract = {The goal of this paper is to analyze how and with what results place-based climate service co-production may be enacted within a community for whom climate change is not a locally salient concern. Aiming to initiate a climate-centered dialogue, a hybrid team of scientists and artists collected local narratives within the Kerourien neighbourhood, in the city of Brest in Brittany, France. Kerourien is a place known for its stigmatizing crime, poverty, marginalization and state of disrepair. Social work is higher on the agenda than climate action. The team thus acknowledged that local narratives might not make much mention of climate change, and recognized part of the work might be to shift awareness to the actual or potential, current or future, connections between everyday non-climate concerns and climate issues. Such a shift called for a practical intervention, centered on local culture. The narrative collection process was dovetailed with preparing the neighbourhood's 50th anniversary celebration and establishing a series of art performances to celebrate the neighbourhood and its residents. Non-climate and quasi-climate stories were collected, documented, and turned into art forms. The elements of climate service co-production in this process are twofold. First, they point to the ways in which non-climate change related local concerns may be mapped out in relation to climate change adaptation, showing how non-climate change concerns call for climate information.

We combined these effects with economic projections to estimate net changes in nutrient availability between 2010 and 2050. Methods: In this modelling study, we used the International Model for Policy Analysis of Agricultural Commodities and Trade to project per capita availability of protein, iron, and zinc in 2050. We used estimated changes in productivity of individual agricultural commodities to model effects on production, trade, prices, and consumption under moderate and high greenhouse gas emission scenarios. Two independent sources of data, which used different methodologies to determine the effect of increased atmospheric CO2 on different key crops, were combined with the modelled food supply results to estimate future nutrient availability. Findings: Although technological change, market responses, and the effects of CO2 fertilisation on yield are projected to increase global availability of dietary protein, iron, and zinc, these increases are moderated by negative effects of climate change affecting productivity and carbon penalties on nutrient content. The carbon nutrient penalty results in decreases in the global availability of dietary protein of 4{\textperiodcentered}1{\%}, iron of 2{\textperiodcentered}8{\%}, and zinc of 2{\textperiodcentered}5{\%} as calculated using one dataset, and decreases in global availability of dietary protein of 2{\textperiodcentered}9{\%}, iron of 3{\textperiodcentered}9{\%}, and zinc of 3{\textperiodcentered}4{\%} using the other dataset. The combined effects of projected increases in atmospheric CO2 (ie, carbon nutrient penalty, CO2 fertilisation, and climate effects on productivity) will decrease growth in the global availability of nutrients by 19{\textperiodcentered}5{\%} for protein, 14{\textperiodcentered}4{\%} for iron, and 14{\textperiodcentered}6{\%} for zinc relative to expected technology and market gains by 2050. The many countries that currently have high levels of nutrient deficiency would continue to be disproportionately affected. Interpretation: This approach is an improvement in estimating future global food security by simultaneously projecting climate change effects on crop productivity and changes in nutrient content under increased concentrations of CO2, which accounts for a much larger effect on nutrient availability than CO2 fertilisation. Regardless of the scenario used to project future consumption patterns, the net effect of increasing concentrations of atmospheric CO2 will slow progress in decreasing global nutrient deficiencies.

Fire activity is controlled by a number of biophysical factors, including climate, whose relevance varies across regions and landscapes. In light of the ongoing climate change, understanding the fire-climate relationships is an issue of current interest in order to identify the most vulnerable regions. Building upon recent global observations of burned areas and climate, we investigate the sensitivity of fire activity to fire-weather across the world's major biomes. We identify the biomes susceptible to inter-annual fire-weather fluctuations, unveiling a non-linear relationship with a saturation threshold past which the area burned can be considered insensitive to increasing fire-weather. Our results depict an unambiguous spatial pattern that identifies the world regions where short-term climate fluctuations are unlikely to produce any significant effect on current fire activity, and those most sensitive to fire-weather changes. In particular, the boreal forests and extensive areas of tropical and subtropical moist broadleaf forests (excluding Africa) as well as sizeable areas of temperate broadleaf forests are identified as highly sensitive. We then present near-future fire-weather scenarios (period 2026-2045) using a state-of-the-art ensemble or Earth System Models (ESMs) from the CMIP5 database, considering a moderate and a high emission scenario (RCPs 4.5 and 8.5). The projected anomalies in fire-weather for the vulnerable temperate biomes are small in magnitude and their direction is either negative or just slightly positive, although significant differences in the projected probability density functions suggest that disruptions of fire regimes may occur locally.

The mountain cryosphere of mainland Europe is recognized to have important impacts on a range of environmental processes. In this paper, we provide an overview on the current knowledge on snow, glacier, and permafrost processes, as well as their past, current, and future evolution. We additionally provide an assessment of current cryosphere research in Europe and point to the different domains requiring further research. Emphasis is given to our understanding of climate–cryosphere interactions, cryosphere controls on physical and biological mountain systems, and related impacts. By the end of the century, Europe's mountain cryosphere will have changed to an extent that will impact the landscape, the hydrological regimes, the water resources, and the infrastructure. The impacts will not remain confined to the mountain area but also affect the downstream lowlands, entailing a wide range of socioeconomical consequences. European mountains will have a completely different visual appearance, in which low- and mid-range-altitude glaciers will have disappeared and even large valley glaciers will have experienced significant retreat and mass loss. Due to increased air temperatures and related shifts from solid to liquid precipitation, seasonal snow lines will be found at much higher altitudes, and the snow season will be much shorter than today. These changes in snow and ice melt will cause a shift in the timing of discharge maxima, as well as a transition of runoff regimes from glacial to nival and from nival to pluvial. This will entail significant impacts on the seasonality of high-altitude water availability, with consequences for water storage and management in reservoirs for drinking water, irrigation, and hydropower production. Whereas an upward shift of the tree line and expansion of vegetation can be expected into current periglacial areas, the disappearance of permafrost at lower altitudes and its warming at higher elevations will likely result in mass movements and process chains beyond historical experience. Future cryospheric research has the responsibility not only to foster awareness of these expected changes and to develop targeted strategies to precisely quantify their magnitude and rate of occurrence but also to help in the development of approaches to adapt to these changes and to mitigate their consequences. Major joint efforts are required in the domain of cryospheric monitoring, which will require coordination in terms of data availability and quality. In particular, we recognize the quantification of high-altitude precipitation as a key source of uncertainty in projections of future changes.

Landslide source areas were commonly limited to surficial soils but also extended into underlying saprolite and bedrock. Slope failures occurred before, during, and after flooding, and many transitioned into long run-out debris flows. Steep slopes in hilly and mountainous regions were particularly impacted by landslides due to antecedent soil moisture levels that were 11{\%}-13{\%} higher than average and rainfall totals of at least 250 mm within a 48 h period. High landslide densities were especially widespread across some geologic formations (e.g., granodiorite of the Utuado batholith); however, bedrock geology alone did not determine the location and distribution of landslides caused by Hurricane Maria. While rainfall data collected during Hurricane Maria were inconsistent, satellite-based soil moisture data were correlated with the distribution of landslides.

To provide more detailed representations of climate processes and impacts, the spatial resolution was N216 (approx. 60 km grid length in mid-latitudes), a higher resolution than the CMIP5 models. We used a set of impacts-relevant indices and a global land surface model to examine the projected changes in weather extremes and their implications for freshwater availability and vulnerability to food insecurity. Uncertainties in regional climate responses are assessed, examining ranges of outcomes in impacts to inform risk assessments. Despite some degree of inconsistency between components of the study due to the need to correct for systematic biases in some aspects, the outcomes from different ensemble members could be compared for several different indicators. The projections for weather extremes indices and biophysical impacts quantities support expectations that the magnitude of change is generally larger for 2°C global warming than 1.5°C. Hot extremes become even hotter, with increases being more intense than seen in CMIP5 projections. Precipitation-related extremes show more geographical variation with some increases and some decreases in both heavy precipitation and drought. There are substantial regional uncertainties in hydrological impacts at local scales due to different climate models producing different outcomes. Nevertheless, hydrological impacts generally point towards wetter conditions on average, with increased mean river flows, longer heavy rainfall events, particularly in South and East Asia with the most extreme projections suggesting more than a doubling of flows in the Ganges at 2°C global warming. Some areas are projected to experience shorter meteorological drought events and less severe low flows, although longer droughts and/or decreases in low flows are projected in many other areas, particularly southern Africa and South America. Flows in the Amazon are projected to decline by up to 25{\%}. Increases in either heavy rainfall or drought events imply increased vulnerability to food insecurity, but if global warming is limited to 1.5°C, this vulnerability is projected to remain smaller than at 2°C global warming in approximately 76{\%} of developing countries.

A new generation of an Earth system model now includes a number of land-surface processes directly relevant to analyzing potential impacts of climate change. This model, HadGEM2-ES, allows us to assess the impacts of climate change, multiple interactions, and feedbacks as the model is run. This paper discusses the results of century-scale HadGEM2-ES simulations from an impacts perspective – specifically, terrestrial ecosystems and water resources – for four different scenarios following the representative concentration pathways (RCPs), used in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC, 2013, 2014). Over the 21st century, simulated changes in global and continental-scale terrestrial ecosystems due to climate change appear to be very similar in all 4 RCPs, even though the level of global warming by the end of the 21st century ranges from 2 °C in the lowest scenario to 5.5° in the highest. A warming climate generally favours broadleaf trees over needleleaf, needleleaf trees over shrubs, and shrubs over herbaceous vegetation, resulting in a poleward shift of temperate and boreal forests and woody tundra in all scenarios. Although climate related changes are slightly larger in scenarios of greater warming, the largest differences between scenarios arise at regional scales as a consequence of different patterns of anthropogenic land cover change. In the model, the scenario with the lowest global warming results in the most extensive decline in tropical forest cover due to a large expansion of agriculture. Under all four RCPs, fire potential could increase across extensive land areas, particularly tropical and sub-tropical latitudes. River outflows are simulated to increase with higher levels of CO2 and global warming in all projections, with outflow increasing with mean temperature at the end of the 21st century at the global scale and in North America, Asia, and Africa. In South America, Europe, and Australia, the relationship with climate warming and CO2 rise is less clear, probably as a result of land cover change exerting a dominant effect in those regions.}, author = {Betts, R A and Golding, N and Gonzalez, P and Gornall, J and Kahana, R and Kay, G and Mitchell, L and Wiltshire, A}, doi = {10.5194/bg-12-1317-2015}, issn = {1726-4189}, journal = {Biogeosciences}, month = {mar}, number = {5}, pages = {1317--1338}, publisher = {Copernicus GmbH}, title = {{Climate and land use change impacts on global terrestrial ecosystems and river flows in the HadGEM2-ES Earth system model using the representative concentration pathways}}, url = {https://bg.copernicus.org/articles/12/1317/2015/}, volume = {12}, year = {2015} } @article{Betzold2015, abstract = {Small island developing states (SIDS) are among the first and worst affected by climate change.

We examined the extent to which artificial drainage infrastructure has altered the potential for saltwater intrusion in the coastal plain of eastern North Carolina. Regional spatial analyses demonstrate that artificial drainages not only lower the overall elevation in coastal landscapes, but they also alter the routing and concentration of hydrological flows. Together, these factors have the potential to increase the total proportion of the landscape vulnerable to saltwater intrusion, not only in areas adjacent to drainage infrastructure but also in places where no artificial drainages exist due to large scale effects of flow rerouting.

Heat stress reduces fruit set of fruiting vegetables, and speeds up development of determinate vegetables, shortening their time for photoassimilation. In both cases, yield losses result with an impaired product quality, thereby increasing production waste. A longer growing season, arising from warmer temperatures, allows a greater number of plantings to be cultivated, contributing to greater annual yields. However, some vegetables need a period of cold accumulation to produce a harvest. Despite the increasing potential for winter cultivation in the future, perennials like asparagus might increasingly suffer from a lack of winter chilling. In cauliflower, higher temperatures will likely cause insufficient vernalization delaying head induction. This review may contribute in improving the adaptation strategies of vegetable production to climate change for a sustainable horticulture due to an effective risk management by meeting the problems of possible waste increase; breeding of new heat, drought and pest tolerant cultivars; secure water resources; increase the use of renewable energy sources; stimulating new ideas in innovative technologies; development of new approaches to secure stable yields and improve the product quality of vegetables for a cleaner production. {\textcopyright} Elsevier.

These concerns are reinforced by evidence of increasing economic losses associated with flooding in many parts of the world, including Europe2. Any changes in river floods would have lasting implications for the design of flood protection measures and flood risk zoning. However, existing studies have been unable to identify a consistent continental-scale climatic-change signal in flood discharge observations in Europe3, because of the limited spatial coverage and number of hydrometric stations. Here we demonstrate clear regional patterns of both increases and decreases in observed river flood discharges in the past five decades in Europe, which are manifestations of a changing climate. Our results—arising from the most complete database of European flooding so far—suggest that: increasing autumn and winter rainfall has resulted in increasing floods in northwestern Europe; decreasing precipitation and increasing evaporation have led to decreasing floods in medium and large catchments in southern Europe; and decreasing snow cover and snowmelt, resulting from warmer temperatures, have led to decreasing floods in eastern Europe. Regional flood discharge trends in Europe range from an increase of about 11 per cent per decade to a decrease of 23 per cent.

We show that important discrepancies at large-scales exist between global and regional projections. The RCMs project at the end of the 21st century over a large area of Europe a summer warming 1.5–2 K colder, and a much smaller decrease of precipitation of 5{\%}, versus 20{\%} in their driving GCMs. The RCMs generally simulate a much smaller increase in shortwave radiation at surface, which directly impacts surface temperature. In addition to differences in cloud cover changes, the absence of time-varying anthropogenic aerosols in most regional simulations plays a major role in the differences of solar radiation changes. We confirm this result with twin regional simulations with and without time-varying anthropogenic aerosols. Additionally, the RCMs simulate larger increases in evapotranspiration over the Mediterranean sea and larger increases/smaller decreases over land, which contribute to smaller changes in relative humidity, with likely impacts on clouds and precipitation changes. Several potential causes of these differences in evapotranspiration changes are discussed.

Extensive savanization, with its loss of forest carbon stock and uptake capacity, is an extreme although very uncertain scenario(1-6). We show that the contrasting rainfall projections simulated for Amazonia by 36 global climate models (GCMs) can be reproduced with empirical precipitation models, calibrated with historical GCM data as functions of the large-scale circulation. A set of these simple models was therefore calibrated with observations and used to constrain the GCM simulations. In agreement with the current hydrologic trends(7,8), the resulting projection towards the end of the twenty-first century is for a strengthening of the monsoon seasonal cycle, and a dry-season lengthening in southern Amazonia. With this approach, the increase in the area subjected to lengthy-savannah-prone-dry seasons is substantially larger than the GCM-simulated one.

New evidence of a multi-decadal drying trend and the impacts of a persistent drought that since 2010 has affected several regions of the country, reinforce the need for clear diagnoses of the hydro-climate changes in Chile. Based on the analysis of long-term records (50+ years) of precipitation and streamflow, we confirm a tendency toward a dryer condition in central-southern Chile (30–48°S). We describe the geographical and seasonal character of this trend, as well as the associated large-scale circulation patterns. When a large ensemble of climate model simulations is contrasted to observations, anthropogenic forcing appears as the leading factor of precipitation change. In addition to a drying trend driven by greenhouse gas forcing in all seasons, our results indicate that the Antarctic stratospheric ozone depletion has played a major role in the summer rainfall decline. Although average model results agree well with the drying trend's seasonal character, the observed change magnitude is two to three times larger than that simulated, indicating a potential underestimation of future projections for this region. Under present-day carbon emission rates, the drying pathway in Chile will likely prevail during the next decades, although the summer signal should weaken as a result of the gradual ozone layer recovery.

This will have a significant impact on coastal areas worldwide, primarily by modifying the shoreline position and coastal morphology, but also by influencing the coastal economy and livelihoods. Generally, it is assumed that sandy barriers will adapt to SLR through shoreline retreat and barrier inland migration. However, for embayed beaches backed by cliffs and/or underlined by shore platforms, constraints to inland migration will compromise such morphological response, with SLR-induced shoreline retreat leading to reductions in beach width and area. This will have impacts on beach use and carrying capacity. Aiming to analyse the morphological changes induced by SLR at cliff-backed platform beaches, this study explores simple mathematical models to quantify beach morphological change. 2D cross-shore profiles, representing the morphology of the beach and the underlying shore platform, were analysed using two geometric models of beach profile response. The model of Taborda and Ribeiro (2015) was applied for profiles with berm, while a new model is proposed for profiles without berm. The models assume that for profiles with berm there is both retreat and rise of the berm, while for profiles without berm the beach face becomes steeper and the sub-aerial beach narrower in response to SLR. Using a high-resolution topo-bathymetric LiDAR dataset, 94 cross-shore profiles from 32 beaches in southern Portugal were analysed. Their evolution was modelled considering the IPCC RCP8.5 scenario, which projects a SLR between 0.5 m and 1 m by 2100. From the 48 profiles with berm, 15 will experience complete berm erosion by 2100 for a 1 m SLR worst case scenario. The modelled average berm/beach width reduction is 7.9/5.8 m and 9.5/9.6 m for a SLR of 0.5 m and 1 m, respectively. A total of 26 beaches will become steeper and may be submerged if a threshold equilibrium beach slope is exceeded. Changes to the beach carrying capacity due to reduction in beach area will impact the local and regional economy, since the southern coast of Portugal is strongly influenced by beach tourism. The modelled changes to beach area result in a maximum potential economic loss ranging between EUR 215,000 and EUR 561,000 per day during peak summer months if no mitigation measures are considered.

The first category was the Standardized Precipitation Index (SPI) accumulated over 3-, 6- and 12-months (hereafter of SPI-3, SPI-6 and SPI-12 respectively). The second category consists of the four Drought Monitoring Indicators (DMI) i.e., Drought Duration (DD), Severity (DS), Intensity (DI) and Frequency (DF). Firstly, analysis of SPI-3, SPI-6 and SPI-12 illustrate that between 1985 and 2016, the Western Cape Province experienced recurrent mild drought conditions. This suggests that the drought conditions experienced during 2015/2016 hydrological year (hereafter current) in the Western Cape Province is a manifestation of past drought conditions. Secondly, analysis of trends in DMI series depict a noticeable spatial-temporal dependence wherein the southern and western regions experienced more severe droughts compared to the eastern and northern regions of the Western Cape Province.

Despite these biases, model simulations show a robust drying pattern for all islands that is generally larger for Puerto Rico (25{\%} annual rainfall reduction for some life zones) than the U.S. Virgin Islands (12{\%} island average). The largest precipitation reductions are found during the more convectively active afternoon and evening hours. Within Puerto Rico, the model uncertainty increases for the wetter life zones, especially for precipitation. Across the life zones, both models project unprecedented maximum and minimum temperatures that may exceed 200 days annually above the historical baseline with only small changes to the frequency of extreme rainfall. By contrast, in the U.S. Virgin Islands, there is no consensus on the location of the largest drying relative to the windward and leeward side of the islands. However, the models project the largest increases in maximum temperature on the southern side of St. Croix and in higher elevations of St. Thomas and St. John.}, author = {Bowden, Jared H. and Terando, Adam J. and Misra, Vasu and Wooten, Adrienne and Bhardwaj, Amit and Boyles, Ryan and Gould, William and Collazo, Jaime A. and Spero, Tanya L.}, doi = {10.1002/joc.6810}, journal = {International Journal of Climatology}, number = {2}, pages = {1305--1327}, title = {{High-resolution dynamically downscaled rainfall and temperature projections for ecological life zones within Puerto Rico and for the U.S. Virgin Islands}}, volume = {41}, year = {2021} } @article{Box2019a, abstract = {Key observational indicators of climate change in the Arctic, most spanning a 47 year period (1971-2017) demonstrate fundamental changes among nine key elements of the Arctic system. We find that, coherent with increasing air temperature, there is an intensification of the hydrological cycle, evident from increases in humidity, precipitation, river discharge, glacier equilibrium line altitude and land ice wastage. Downward trends continue in sea ice thickness (and extent) and spring snow cover extent and duration, while near-surface permafrost continues to warm. Several of the climate indicators exhibit a significant statistical correlation with air temperature or precipitation, reinforcing the notion that increasing air temperatures and precipitation are drivers of major changes in various components of the Arctic system. To progress beyond a presentation of the Arctic physical climate changes, we find a correspondence between air temperature and biophysical indicators such as tundra biomass and identify numerous biophysical disruptions with cascading effects throughout the trophic levels. These include: increased delivery of organic matter and nutrients to Arctic near-coastal zones; condensed flowering and pollination plant species periods; timing mismatch between plant flowering and pollinators; increased plant vulnerability to insect disturbance; increased shrub biomass; increased ignition of wildfires; increased growing season CO2 uptake, with counterbalancing increases in shoulder season and winter CO2 emissions; increased carbon cycling, regulated by local hydrology and permafrost thaw; conversion between terrestrial and aquatic ecosystems; and shifting animal distribution and demographics.

A gridded daily precipitation and temperature dataset based on observations is used to drive and validate the VIC macro-scale hydrological model in the region of interest. Historical and future simulations from 19 climate models participating in CMIP5 have been adjusted with the observational dataset and then used to make hydrological projections. By the end of the century, there is a large difference between the scenarios, with projected warming of ∼ + 1.2 °C (RCP2.6), ∼ + 3.5 °C (RCP8.5) and drying of ∼ − 3{\%} (RCP2.6), ∼ − 30{\%} (RCP8.5). Following the strong drying and warming projected in this region under the RCP8.5 scenario, the VIC model simulates decreases in annual runoff of about 40{\%} by the end of the century. Such strong regional effect of climate change may have large implications for the water resources of this region. Even under the low emission scenario, the Andes snowpack is projected to decrease by 35–45{\%} by mid-century. In more snowmelt-dominated areas, the projected hydrological changes under RCP8.5 go together with more loss in the snowpack (75–85{\%}) and a temporal shift in the center timing of runoff to earlier dates (up to 5 weeks by the end of the century). The severity and frequency of extreme hydroclimatic events are also projected to increase in the future. The occurrence of extended droughts, such as the recently experienced mega-drought (2010–2015), increases from one to up to five events per 100 years under RCP8.5. Concurrently, probability density function of 3-day peak runoff indicates an increase in the frequency of flood events. The estimated return periods of 3-day peak runoff events depict more drastic changes and increase in the flood risk as higher recurrence intervals are considered by mid-century under RCP2.6 and RCP8.5, and by the end of the century under RCP8.5.}, author = {Bozkurt, Deniz and Rojas, Maisa and Boisier, Juan Pablo and Valdivieso, Jon{\'{a}}s}, doi = {10.1007/s10584-018-2246-7}, issn = {0165-0009}, journal = {Climatic Change}, month = {oct}, number = {3-4}, pages = {131--147}, title = {{Projected hydroclimate changes over Andean basins in central Chile from downscaled CMIP5 models under the low and high emission scenarios}}, url = {http://link.springer.com/10.1007/s10584-018-2246-7}, volume = {150}, year = {2018} } @article{nhess-18-2047-2018, author = {Br{\"{o}}nnimann, S and Rajczak, J and Fischer, E M and Raible, C C and Rohrer, M and Sch{\"{a}}r, C}, doi = {10.5194/nhess-18-2047-2018}, journal = {Natural Hazards and Earth System Sciences}, number = {7}, pages = {2047--2056}, title = {{Changing seasonality of moderate and extreme precipitation events in the Alps}}, url = {https://nhess.copernicus.org/articles/18/2047/2018/}, volume = {18}, year = {2018} } @article{Braganca2016, abstract = {Objetivou-se com este trabalho definir, por meio do zoneamento agroclimatol{\'{o}}gico atual e para os pr{\'{o}}ximos 100 anos, {\'{a}}reas com diferentes aptid{\~{o}}es clim{\'{a}}ticas para a cultura do caf{\'{e}} ar{\'{a}}bica (Coffea arabica L.), no estado do Esp{\'{i}}rito Santo.

According to data published by the National Atmospheric Deposition Network (NADP), over the past 17years Ca2+ deposition has increased over large regions of the US. A trend analysis to determine regions of significant change in Ca2+ deposition revealed statistically significant increases in three broad regions within the western half of the country: the inter-mountain west, the midwest, and the northwest. We evaluated potential changes in sources of calcium to the atmosphere including soil erosion, industrial emissions, forest fires, and sea-salt aerosols to determine the cause of rising atmospheric calcium deposition. Based on our evaluation, the most parsimonious explanation for increased Ca2+ deposition is an increase in mineral aerosol emissions from within the western US. This explanation is corroborated by independent evidence showing increases in the frequency of dust storms and low-visibility days across regions of the western US. Furthermore, our analysis indicates that the increase in mineral aerosol emissions is most likely due to (1) increased aridity and wind transport and (2) increased area and intensity of upwind human activities. Changes in atmospheric dust concentrations can have important ecological implications through the contribution of acid neutralizing capacity to both precipitation and regions of deposition. Thus increased dust emissions have the potential to ameliorate the detrimental effects of acid precipitation on terrestrial ecosystems, though dust may exacerbate the impacts of air quality on human health. {\textcopyright} 2013 Elsevier B.V.}, author = {Brahney, J. and Ballantyne, A.

It also outlines a series of scenarios of climate change impacts on fish production and ecosystems through case studies in different regions and ecosystems. The second paper tackles the consequences of climate change impacts on fisheries and their dependent communities. It analyses the exposure, sensitivity and vulnerability of fisheries to climate change and presents examples of adaptive mechanisms currently used in the sector. The contribution of fisheries to greenhouse gas emissions is addressed and examples of mitigation strategies are given. The role of public policy and institutions in promoting climate change adaptation and mitigation is also explored. Finally, the third paper addresses the impacts of climate change on aquaculture. It provides an overview of the current food fish and aquaculture production and a synthesis of existing studies on climate change effects on aquaculture and fisheries.

Recent droughts caused greatly elevated fire-induced tree mortality in a fire experiment and widespread regional forest fires that burned 5-2{\%} of southeastern Amazon forests. These results suggest that feedbacks between fires and extreme climatic conditions could increase the likelihood of an Amazon forest 'dieback' in the near-term. To secure the integrity of seasonally dry Amazon forests, efforts to end deforestation must be accompanied by initiatives that reduce the accidental spread of land management fires into neighboring forest reserves and effectively suppress forest fires when they start.Interactions between climate and land-use change may drive widespread degradation of Amazonian forests. High-intensity fires associated with extreme weather events could accelerate this degradation by abruptly increasing tree mortality, but this process remains poorly understood. Here we present, to our knowledge, the first field-based evidence of a tipping point in Amazon forests due to altered fire regimes. Based on results of a large-scale, long-term experiment with annual and triennial burn regimes (B1yr and B3yr, respectively) in the Amazon, we found abrupt increases in fire-induced tree mortality (226 and 462{\%}) during a severe drought event, when fuel loads and air temperatures were substantially higher and relative humidity was lower than long-term averages. This threshold mortality response had a cascading effect, causing sharp declines in canopy cover (23 and 31{\%}) and aboveground live biomass (12 and 30{\%}) and favoring widespread invasion by flammable grasses across the forest edge area (80 and 63{\%}), where fires were most intense (e.g., 220 and 820 kW.m-1). During the droughts of 2007 and 2010, regional forest fires burned 12 and 5{\%} of southeastern Amazon forests, respectively, compared with {\textless}1{\%} in nondrought years. These results show that a few extreme drought events, coupled with forest fragmentation and anthropogenic ignition sources, are already causing widespread fire-induced tree mortality and forest degradation across southeastern Amazon forests.

Results were compared to recharge estimated using the 2017 baseline land cover to understand how changing land management and climate could influence groundwater recharge. Estimated recharge increased island-wide under all future land cover and climate combinations and was dominated by specific land cover transitions. For the dry future climate, recharge for land cover Futures 1 to 4 increased by 12{\%}, 0.7{\%}, 0.01{\%}, and 11{\%} relative to 2017 land cover conditions, respectively. Corresponding increases under the wet future climate were 10{\%}, 0.9{\%}, 0.6{\%}, and 9.3{\%}.

There are three main barriers that GLISA encounters at the onset of many of the case studies: (1) mismatched terminology used by scientists and stakeholders to describe the types of information that are available and needed for problem solving (translation); (2) unrealistic expectations regarding the development of climate information products for problem solving; and (3) disordered integration of when stakeholders want to bring climate information into decision-making processes.

In this paper we describe in detail GLISA's experiences that have led to the realization of these barriers and the steps GLISA has taken to overcome them.

Water transport and water constituents vary, however, across a very diverse geography. In this paper, which is a component of the Arctic Freshwater Synthesis, we review the central freshwater processes in the terrestrial Arctic drainage and how they function and change across seven hydrophysiographical regions (Arctic tundra, boreal plains, shield, mountains, grasslands, glaciers/ice caps, and wetlands). We also highlight links between terrestrial hydrology and other components of the Arctic freshwater system. In terms of key processes, snow cover extent and duration is generally decreasing on a pan-Arctic scale, but snow depth is likely to increase in the Arctic tundra. Evapotranspiration will likely increase overall, but as it is coupled to shifts in landscape characteristics, regional changes are uncertain and may vary over time. Streamflow will generally increase with increasing precipitation, but high and low flows may decrease in some regions. Continued permafrost thaw will trigger hydrological change in multiple ways, particularly through increasing connectivity between groundwater and surface water and changing water storage in lakes and soils, which will influence exchange of moisture with the atmosphere. Other effects of hydrological change include increased risks to infrastructure and water resource planning, ecosystem shifts, and growing flows of water, nutrients, sediment, and carbon to the ocean.

Nevertheless, their role in sediment mobilization and denudation remains poorly quantified, especially at the global scale. Based on an extensive literature review, we compiled measured contemporary landslide mobilization rates (i.e. the average annual volume of hillslope material displaced per unit area; LMR, [m³/km²/y]) from 116 study areas worldwide. Using this dataset, we calibrated and validated a multiple regression model that simulates global patterns of LMR at decadal timescales. This model explains about 62{\%} of the observed variance in LMR based on topography, seismicity and lithology. By applying this model at the global scale and accounting for uncertainties due to observation and prediction errors, we estimate that annually about 56 billion m³ (∼100 gigaton) is mobilized by landslides worldwide. Intercontinental and interregional differences are large with Asia accounting for 68{\%} (38 billion m³) of the global LMR. The Central and Southeast Asian mountain ranges (including the Himalaya and Karakoram) account for 50{\%} (28 billion m³) of this rate, while covering only 2{\%} of the Earth's terrestrial surface. Comparisons of our simulated LMR with other data and models from literature suggest that, in highly tectonically active regions, around 70{\%} of the mobilized landslide volumes are due to earthquake-triggered landslides. At the global scale, the contribution of coseismic landsliding to the total landslide mobilization rate is likely in the order of 30–40{\%}. Using available databases of measured catchment sediment yield (SY), we also conducted a statistical comparison between measured SY and estimated LMR for nearly 3000 catchments in Europe and Africa. We observe highly significant relationships between LMR and SY for Europe (R²: 0.35, p {\textless} 0.001) and Africa (R²: 0.2, p {\textless} 0.001). Furthermore, landslide mobilization rates are typically larger than the corresponding SY. Overall, this study provides a first estimation of the global patterns of LMR. The results confirm the importance of landsliding as a dominant process of landscape denudation and sediment mobilization, but also illustrate the huge regional variations that characterize this process as well as the importance of sediment dynamics within catchments.}, author = {Broeckx, Jente and Rossi, Mauro and Lijnen, Kobe and Campforts, Benjamin and Poesen, Jean and Vanmaercke, Matthias}, doi = {10.1016/j.earscirev.2019.102972}, journal = {Earth-Science Reviews}, keywords = {Empirical model,Global dataset,Landslide mobilization,Lithology,Local relief,Mass movement,Sediment yield,Seismicity}, month = {feb}, pages = {102972}, title = {{Landslide mobilization rates: A global analysis and model}}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0012825219302557 http://www.sciencedirect.com/science/article/pii/S0012825219302557}, volume = {201}, year = {2020} } @article{Bromirski2013, author = {Bromirski, Peter D and Cayan, Daniel R and Helly, John and Wittmann, Paul}, doi = {10.1002/2013JC009189}, issn = {21699275}, journal = {Journal of Geophysical Research: Oceans}, month = {dec}, number = {12}, pages = {6329--6348}, publisher = {Wiley Online Library}, title = {{Wave power variability and trends across the North Pacific}}, url = {http://doi.wiley.com/10.1002/2013JC009189}, volume = {118}, year = {2013} } @article{Brooks2013, abstract = {As the planet warms, it is important to consider possible impacts of climate change on severe thunderstorms and tornadoes. To further that discussion, the current distribution of severe thunderstorms as a function of large-scale environmental conditions is presented. Severe thunderstorms are much more likely to form in environments with large values of convective available potential energy (CAPE) and deep-tropospheric wind shear. Tornadoes and large hail are preferred in high-shear environments and non-tornadic wind events in low shear. Further, the intensity of tornadoes and hail, given that they occur, tends to be almost entirely a function of the shear and only weakly depends on the thermodynamics.Climate model simulations suggest that CAPE will increase in the future and the wind shear will decrease. Detailed analysis has suggested that the CAPE change will lead to more frequent environments favorable for severe thunderstorms, but the strong dependence on shear for tornadoes, particularly the strongest ones, and hail means that the interpretation of how individual hazards will change is open to question. The recent development of techniques to use higher-resolution models to estimate the occurrence of storms of various kinds is discussed.

This note describes the process to update a Canadian historical snow survey dataset to 2016 and the production of a 0.1° gridded version for research applications. Analysis of trends in SWE, snow depth (SD), and density over the 50-year period from 1967 to 2016 revealed large spatial variability in trend sign and strength, with a relatively small percentage of points showing statistically significant trends. Where SWE and SD trends were significant, they tended to be negative, which is consistent with previous investigations of snow cover changes in Canada. The results show evidence of a latitudinal dependence in SWE trends, with the largest negative trends occurring over lower latitudes, and a tendency for mainly positive trends in Arctic SWE, which is consistent with observations from Russia and climate model projections of the response of Arctic snow cover to climate warming. Arctic sites also showed evidence of an increasing trend in 1 April snowpack density of 6.6 kg m−3 per decade but little corresponding change in SD. This has potentially important consequences for the soil thermal regime because it provides a cooling influence from an increase in the snowpack effective thermal conductivity.

In addition, common barriers and enablers to the uptake of climate information were also noted including the format of the information provided, the need for compatibility with existing in-house systems, and the perceived credibility and trust of information providers.

Two of these would be the need to justify public and private investment in the provision of SCF and demonstrating the gains and benefits of using SCF in specific decision-making contexts. This paper reviews the main factors influencing how SCF is (or can be) valued in supporting decision-making and the main methods and metrics currently used to perform such valuations. Our review results in four key findings: (a) there is a current emphasis on economic ex ante studies and the quantification of SCF value; (b) there are fundamental differences in how the value of SCF is defined and estimated across methods and approaches; (c) most valuation methods are unable to capture the differential benefits and risks of using SCF across spatiotemporal scales and groups; and (d) there is limited involvement of the decision-makers in the valuation process. The paper concludes by providing some guiding principles towards more effective valuations of SCF, notably the need for a wider diversity and integration of methodological approaches. These should particularly embrace ex-post, qualitative, and participatory approaches which allow co-evaluation with decision-makers so that more comprehensive and equitable SCF valuations can be developed in future.

The aim of this paper is to identify the barriers and enablers to the use of SCF across organisations in Europe. To achieve that, we conducted 75 in-depth interviews with organisations working across eight sectors (including energy, transport, water and agriculture) and 16 countries. The majority of the organisations interviewed do not currently use SCF. This was due to the low reliability and skill of SCF in Europe but also with other non-technical aspects such as the lack of relevance and awareness of SCF in the organisations. Conversely, the main enabler to the use of SCF was the interactions with the providers of SCF. In addition, the level of organisational resources, capacity and expertise were also significant enablers to the use of SCF in organisations. This paper provides the first empirical assessment of the use of SCF in Europe.

Climate change impacts on habitat suitability and demography are often studied, but direct effects on plant dispersal are rarely considered. To address this we analysed climate model projections of future wind speeds and modelled their possible impacts on dispersal and spread of wind-dispersed plants. 2. Projections for 17 Global Climate Models and three emission scenarios suggested great uncertainty about wind speeds in southern England by the period 2070-99. Projections ranged from -90{\%} to +100{\%} change in the mean wind speed, although the average projection was for large falls in both summer and winter wind speeds. 3. Using a novel method for converting projected changes in mean wind speed to new seasonal wind speed distributions, we parameterized a mechanistic model of seed dispersal by wind using baseline and changes in mean wind speed from -80{\%} to +80{\%}. 4. The mechanistic seed dispersal model was combined with demographic data in an analytical model of plant spread. This was carried out for three British native and three non-native species, which represented a range of life-forms. 5. Dispersal kernels and population spread rates were affected disproportionately by changes in wind speed, demonstrating nonlinear propagation of uncertainty in wind speed projections through to modelled plant spread rates. 6. Sensitivity analyses showed differences among the plant species in which demographic transitions were most important in determining spread rates. By contrast, sensitivity of spread rates to dispersal parameters showed great consistency among species, with seed release height being more important than seed terminal velocity. 7. Synthesis. Plant populations will need to shift their geographic ranges to keep pace with climate change-driven habitat loss. This study shows that climate change may affect that ability by decreasing the dispersal distances of wind-dispersed plants and thus their potential spread rates. However, the modelling approach presented here illustrates that uncertainty in climate models leads to an even greater uncertainty about how dispersal and spread will change in future climates. Caution should therefore be exercised in making predictions as to how fast plant species may spread in response to climate change. {\textcopyright} 2012 The Authors.

Hail observations from weather stations and model reanalysis data were used to document the spatial and temporal distributions, variabilities, and environments of hail events. The results show that hail occurs most frequently in mountainous areas, while the smallest average number of hail days per year is found in the southeast. Herein, the convective season was defined as April–September, given that 94.2{\%} of all mean monthly hail days were identified in this period. During the convective season the hail events prevail with most of these occurring in the afternoon and evening hours between 1000 and 1800 UTC. The severe hail events occur, overall, between 1400 and 1600 UTC, while in the southwest severe hail occurs later between 1600 and 1900 UTC. The spatial distribution of the convective parameters is consistent with the spatial distribution of hail days, revealing that hail is not favored in southeastern Romania, but in the rest of the country. The trend analysis of mean hail days per year disclose that 55.2{\%} of all stations show a statistically significant upward trend, 3.8{\%} show a statistically significant downward trend, while 40.9{\%} show no statistically significant trend. A correlation between the variability of hail days per year and the variability in the occurrence of low pressure systems of Atlantic origin exists, the latter generating low pressure systems over the Mediterranean Sea that supply eastern Europe with the moist air needed for convection. }, author = {Burcea, Sorin and Cică, Roxana and Bojariu, Roxana}, doi = {10.1175/MWR-D-16-0126.1}, journal = {Monthly Weather Review}, number = {11}, pages = {4289--4299}, title = {{Hail Climatology and Trends in Romania: 1961–2014}}, url = {https://doi.org/10.1175/MWR-D-16-0126.1}, volume = {144}, year = {2016} } @article{Burkart2011, abstract = {This study assessed the effect of temperature and thermal atmospheric conditions on all-cause and cardiovascular mortality in Bangladesh.

Here we analyze rainfall data from the city catchment areas, including rare centennial records from the surrounding region, to assess the severity of the 2015–2017 drought. We find that there has been a long-term decline in the number of winter rainfall days, but this trend has been generally masked by fluctuations in rainfall intensity. The recent drought is unprecedented in the centennial record and represents a combination of the long-term decline in rainfall days and a more recent decline in rainfall intensity. Cold fronts during the winter months are responsible for most of the rainfall reaching Cape Town and our analysis shows no robust regional trend in the number of fronts over the last 40 years. Rather, the observed multidecadal decline in rainfall days, which threatens to increase the occurrence of severe drought, appears to be linked to a decrease in the duration of rainfall events associated with cold fronts. This change in rainfall characteristics associated with fronts appears to be linked to Hadley Cell expansion seen across the Southern Hemisphere and an increasing trend in post-frontal high-pressure conditions that suppress orographically enhanced rainfall.}, author = {Burls, Natalie J. and Blamey, Ross C. and Cash, Benjamin A. and Swenson, Erik T. and al Fahad, Abdullah and Bopape, Mary Jane M. and Straus, David M. and Reason, Chris J.C.}, doi = {10.1038/s41612-019-0084-6}, issn = {23973722}, journal = {npj Climate and Atmospheric Science}, keywords = {Atmospheric dynamics,Climate change}, month = {dec}, number = {1}, pages = {1--8}, publisher = {Nature Research}, title = {{The Cape Town “Day Zero” drought and Hadley cell expansion}}, url = {https://doi.org/10.1038/s41612-019-0084-6}, volume = {2}, year = {2019} } @article{Burn2016, author = {Burn, D H and Whitfield, P H}, doi = {10.1080/07011784.2015.1026844}, journal = {Canadian Water Resources Journal}, number = {1-2}, pages = {139--150}, title = {{Changes in floods and flood regimes in Canada}}, volume = {41}, year = {2016} } @article{Burrows2014a, author = {Burrows, Michael T. and Schoeman, David S. and Richardson, Anthony J. and Molinos, Jorge Garc{\'{i}}a and Hoffmann, Ary and Buckley, Lauren B. and Moore, Pippa J. and Brown, Christopher J. and Bruno, John F. and Duarte, Carlos M. and Halpern, Benjamin S. and Hoegh-Guldberg, Ove and Kappel, Carrie V. and Kiessling, Wolfgang and O'Connor, Mary I. and Pandolfi, John M. and Parmesan, Camille and Sydeman, William J. and Ferrier, Simon and Williams, Kristen J. and Poloczanska, Elvira S.}, doi = {10.1038/nature12976}, issn = {0028-0836}, journal = {Nature}, month = {mar}, number = {7493}, pages = {492--495}, title = {{Geographical limits to species-range shifts are suggested by climate velocity}}, url = {http://www.nature.com/articles/nature12976}, volume = {507}, year = {2014} } @article{Riahi2018, abstract = {Understanding the interplay between multiple climate change risks and socioeconomic development is increasingly required to inform effective actions to manage these risks and pursue sustainable development.

The analysis includes changes in drought intensity and water stress index, cooling demand change and heat event exposure, habitat degradation and crop yield, amongst others.

The greatest uncertainty in simulating water use, potential evapotranspiration, crop transpiration and soil evaporation was due to differences in how crop transpiration was modelled and accounted for 50{\%} of the total variability among models. The simulation results for the sensitivity to temperature indicated that crop WU will decline with increasing temperature due to reduced growing seasons. The uncertainties in simulated crop WU, and in particularly due to uncertainties in simulating crop transpiration, were greater under conditions of increased temperatures and with high temperatures in combination with elevated atmospheric [CO2] concentrations.

Global multimodel wave climate projections are obtained at 1.0° × 1.0° scale from 30 Coupled Model Intercomparison Project Phase 5 (CMIP5) global circulation model (GCM) realizations. A semi-supervised weather-typing approach based on a characterization of the ocean wave generation areas and the historical wave information from the recent GOW2 database are used to train the statistical model. This framework is also applied to obtain high resolution projections of coastal wave climate and coastal impacts as port operability and coastal flooding. Regional projections are estimated using the collection of weather types at spacing of 1.0°. This assumption is feasible because the predictor is defined based on the wave generation area and the classification is guided by the local wave climate. The assessment of future changes in coastal impacts is based on direct downscaling of indicators defined by empirical formulations (total water level for coastal flooding and number of hours per year with overtopping for port operability). Global multimodel projections of the significant wave height and peak period are consistent with changes obtained in previous studies. Statistical confidence of expected changes is obtained due to the large number of GCMs to construct the ensemble. The proposed methodology is proved to be flexible to project wave climate at different spatial scales.

Qualitative historical analysis of glacier hazard management since 1970 allows us to identify and explain why certain actions and policies to reduce risk were implemented or omitted. We extrapolate these case-specific variables to generate a broader socio-environmental framework identifying factors that can facilitate or impede disaster risk reduction and climate change adaptation. Facilitating factors are technical capacity, disaster events with visible hazards, institutional support, committed individuals, and international involvement. Impediments include divergent risk perceptions, imposed government policies, institutional instability, knowledge disparities, and invisible hazards. This framework emerges from an empirical analysis of a coupled social-ecological system and offers a holistic approach for integrating disaster risk reduction and climate change adaptation. {\textcopyright} 2011 Springer Science+Business Media B.V.}, author = {Carey, Mark and Huggel, Christian and Bury, Jeffrey and Portocarrero, C{\'{e}}sar and Haeberli, Wilfried}, doi = {10.1007/s10584-011-0249-8}, issn = {0165-0009}, journal = {Climatic Change}, month = {jun}, number = {3-4}, pages = {733--767}, title = {{An integrated socio-environmental framework for glacier hazard management and climate change adaptation: lessons from Lake 513, Cordillera Blanca, Peru}}, url = {http://link.springer.com/10.1007/s10584-011-0249-8}, volume = {112}, year = {2012} } @misc{Carey-Smith2010, abstract = {Abstract An analysis of daily precipitation output from a regional climate model was undertaken in order to estimate future changes in precipitation extremes for New Zealand. Daily rainfall for present (1971—2000) and future (2071—2100) climate under the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios A2 and B2 emission scenarios, was simulated by the regional climate model PRECIS, developed at the UK Met Office Hadley Centre. Return values of 1-day precipitation extreme for a 5-year return period were calculated from a generalized Pareto extreme value model fitted to the tail of the rainfall distribution. A test of the statistical analysis in several regions of New Zealand revealed that the generalized Pareto model was appropriate for estimating daily precipitation extremes over the country for short return periods, but was unable to realistically capture the changes in longer return periods under transient climate change. For long return periods, a separate analysis of the regional climate model simulations suggested that the increase in the heaviest rainfall extremes in the country has an upper limit in the range of between 7 to 9{\%} per Kelvin of warming. Similarly, an ensemble of global climate models from the Coupled Model Intercomparison Project 3, suggested an increase of 5 to 12{\%} per Kelvin.

The motivation for this study is the observation that drought risk is increasing globally and the effective regulation of prevention and adaptation measures depends on dH magnitude and its distribution for the future. Based on the Weighted Anomaly of Standardized Precipitation index, dH changes have been assessed for mid-(2021–2050) and late-century (2071–2099). With a few exceptions, results show a likely increase in global dH between the historical years (1971–2000) and both future time periods under all RCPs. Notwithstanding this worsening trend, it was found that projections of dH changes for most regions are neither robust nor significant in the near-future. By the end of the century, greater increases are projected for RCPs describing stronger radiative forcing. Under RCP8.5, statistically significant dH changes emerge for global Mediterranean ecosystems and the Amazon region, which are identified as possible hotspots for future water security issues. Taken together, projections of dH changes point towards two dilemmas: (1) in the near-term, stake-holders are left worrying about projected increasing dH over large regions, but lack of actionable model agreement to take effective decisions related to local prevention and adaptation initiatives; (2) in the long-term, models demonstrate remarkable agreement, but stake-holders lack actionable knowledge to manage potential impacts far distant from actual human-dominated environments.

Which rates should coastal scientists and managers apply in their studies, and what is the degree of confidence of such forecasts, are still open questions.This paper reviews the patterns and effects of relative SLR (RSLR) in coastal lagoons. Three main components are presented in the review: (a) a summary of the main approaches used in predicting medium- to long-term trends in RSLR, (b) a summary of the main evolutionary trends of coastal lagoons and the tools used to examine such trends, and (c) an identification of future research needs.The review reveals that the major source of uncertainty is how and when RSLR will manifest itself at different spatio-temporal scales in coastal lagoon systems, and how its effects can be mitigated. Most of the studies reviewed herein articulate a natural 'defence' mechanism of barriers in coastal lagoons by landward barrier retreat through continuous migration, and a gradual change in basin hypsometry during the retreat process. So far, only a relatively small number of detailed studies have integrated and quantified human impacts and coastal lagoon evolution induced by RSLR. We conclude that much more research about adaptation measures is needed, taking into consideration not only the physical and ecological systems but also social, cultural, and economic impacts.

They are a pervasive natural hazard worldwide. They have an association with climate primarily via glacier mass balance and their impacts on society partly depend on population pressure and land use. Given the ongoing changes in climate and land use and population distributions there is therefore an urgent need to discriminate the spatio-temporal patterning of glacier outburst floods and their impacts. This study presents data compiled from 20 countries and comprising 1348 glacier floods spanning 10 centuries. Societal impacts were assessed using a relative damage index based on recorded deaths, evacuations, and property and infrastructure destruction and disruption. These floods originated from 332 sites; 70{\%} were from ice-dammed lakes and 36{\%} had recorded societal impact. The number of floods recorded has apparently reduced since the mid-1990s in all major world regions. Two thirds of sites that have produced {\textgreater} 5 floods (n = 32) have floods occurring progressively earlier in the year. Glacier floods have directly caused at least: 7 deaths in Iceland, 393 deaths in the European Alps, 5745 deaths in South America and 6300 deaths in central Asia. Peru, Nepal and India have experienced fewer floods yet higher levels of damage. One in five sites in the European Alps has produced floods that have damaged farmland, destroyed homes and damaged bridges; 10{\%} of sites in South America have produced glacier floods that have killed people and damaged infrastructure; 15{\%} of sites in central Asia have produced floods that have inundated farmland, destroyed homes, damaged roads and damaged infrastructure. Overall, Bhutan and Nepal have the greatest national-level economic consequences of glacier flood impacts. We recommend that accurate, full and standardised monitoring, recording and reporting of glacier floods is essential if spatio-temporal patterns in glacier flood occurrence, magnitude and societal impact are to be better understood.

Projecting changes in snow cover due to climate warming is important for many societal issues, including the adaptation of avalanche risk mitigation strategies. Efficient modelling of future snow cover requires high resolution to properly resolve the topography. Here, we introduce results obtained through statistical downscaling techniques allowing simulations of future snowpack conditions including mechanical stability estimates for the mid and late 21st century in the French Alps under three climate change scenarios. Refined statistical descriptions of snowpack characteristics are provided in comparison to a 1960–1990 reference period, including latitudinal, altitudinal and seasonal gradients. These results are then used to feed a statistical model relating avalanche activity to snow and meteorological conditions, so as to produce the first projection on annual/seasonal timescales of future natural avalanche activity based on past observations. The resulting statistical indicators are fundamental for the mountain economy in terms of anticipation of changes. Whereas precipitation is expected to remain quite stationary, temperature increase interacting with topography will constrain the evolution of snow-related variables on all considered spatio-temporal scales and will, in particular, lead to a reduction of the dry snowpack and an increase of the wet snowpack. Overall, compared to the reference period, changes are strong for the end of the 21st century, but already significant for the mid century. Changes in winter are less important than in spring, but wet-snow conditions are projected to appear at high elevations earlier in the season. At the same altitude, the southern French Alps will not be significantly more affected than the northern French Alps, which means that the snowpack will be preserved for longer in the southern massifs which are higher on average. Regarding avalanche activity, a general decrease in mean (20–30{\%}) and interannual variability is projected. These changes are relatively strong compared to changes in snow and meteorological variables. The decrease is amplified in spring and at low altitude. In contrast, an increase in avalanche activity is expected in winter at high altitude because of conditions favourable to wet-snow avalanches earlier in the season. Comparison with the outputs of the deterministic avalanche hazard model MEPRA (Mod{\`{e}}le Expert d'aide {\`{a}} la Pr{\'{e}}vision du Risque d'Avalanche) shows generally consistent results but suggests that, even if the frequency of winters with high avalanche activity is clearly projected to decrease, the decreasing trend may be less strong and smooth than suggested by the statistical analysis based on changes in snowpack characteristics and their links to avalanches observations in the past. This important point for risk assessment pleads for further work focusing on shorter timescales. Finally, the small differences between different climate change scenarios show the robustness of the predicted avalanche activity changes.}, author = {Castebrunet, H. and Eckert, N. and Giraud, G. and Durand, Y. and Morin, S.}, doi = {10.5194/tc-8-1673-2014}, isbn = {1994-0440}, issn = {1994-0424}, journal = {The Cryosphere}, month = {sep}, number = {5}, pages = {1673--1697}, title = {{Projected changes of snow conditions and avalanche activity in a warming climate: the French Alps over the 2020–2050 and 2070–2100 periods}}, url = {https://www.the-cryosphere.net/8/1673/2014/}, volume = {8}, year = {2014} } @article{Catto2012, abstract = {Precipitation over the north of Australia mainly falls during the wet season and is associated with the Australian monsoon. Recent studies have shown that precipitation in the north and northwest of Australia during the wet season has increased over the past 50 years. In previous work, daily radiosonde data at a single site (Darwin) were used to identify five distinct wet season regimes, each associated with a characteristic synoptic circulation pattern and rainfall probability distribution. Here the five regimes are used to decompose the 50-year precipitation trend at Darwin from 1957/1958?2007/2008 into two contributions; that due to changes in the regime relative frequency of occurrence, and that due to changes in the within-regime precipitation. Over the entire wet season from September to April, the within-regime precipitation does not change significantly for any of the regimes. However, the relative frequency of occurrence decreases significantly for the driest regimes, and increases significantly for one of the wettest regimes, suggesting that changes in the large-scale circulation are a more important contributor to the precipitation trends than are thermodynamic changes. During December to March, the largest contributions to the total precipitation trend come from changes in all three of the wettest regimes. During November and April, when the average precipitation is lower, there is a large relative contribution to the precipitation trend from the increase in frequency of a wet regime and a decrease in frequency of the dry regimes.

We analyzed annual averages, maxima, minima, and seasonality of a 36-year data set (1975–2010) of 675 rainfall and 140 streamflow gauges. Results reveal that large trends are widespread in Southern Brazil, especially in basins with areas smaller than 10,000 km2. Changes in the rainfall regime did not directly translate into changes in the streamflow regime. Changes in the annual maximum flow of forested basins were not statistically significant even when the annual average and maximum rainfall increased significantly.

However, as climate change and uncontrolled development are likely to increase urban flooding in the future, general improvements could be made to improve knowledge transfer: e.g., develop means to work across policy silos and strike compromises between conflicting sectoral responsibilities, and develop long-term integrated strategies using planning tools and practices to address growing risk. While knowledge transfer cannot be direct because of different geographical settings, socio-economic situations, and political situations, we encourage governments to look beyond engineering-based flood control structures as to develop flood governance programs.}, author = {Chan, F K S and Chuah, C Joon and Ziegler, A D and D{\c{a}}browski, M and Varis, O}, doi = {10.1016/j.jclepro.2018.03.217}, issn = {0959-6526}, journal = {Journal of Cleaner Production}, keywords = {Climate adaptation,Coastal cities,Flood risk management,Hong Kong and Singapore,Resilience}, pages = {576--589}, title = {{Towards resilient flood risk management for Asian coastal cities: Lessons learned from Hong Kong and Singapore}}, url = {http://www.sciencedirect.com/science/article/pii/S0959652618308941}, volume = {187}, year = {2018} } @article{Chan2012b, abstract = {Asia?s urbanized mega-deltas are experiencing increased incidences of flooding.

The recent history of flooding in Asia?s deltaic cities and the drivers of that risk have been examined in this article. We give particular attention to the Pearl River Delta, and its cities of Guangzhou, Hong Kong and Shenzhen, important economic centres of Asia. The flood risk is substantial, but flood risk management appear to suffer through a lack of sufficient strategic planning, and the difficulty of defending deltaic cities through traditional engineering approaches alone.

Although cyclone frequency is unlikely to rise, cyclone intensity is predicted to increase globally, causing more frequent occurrences of the most destructive cyclones with potentially severe consequences for coral reef ecosystems. While increasing heat stress is considered a pervasive risk to coral reefs, quantitative estimates of threats from cyclone intensification are lacking due to limited data on cyclone impacts to inform projections. Here, using extensive data from Australia's Great Barrier Reef (GBR), we show that increases in cyclone intensity predicted for this century are sufficient to greatly accelerate coral reef degradation. Coral losses on the outer GBR were small, localized and offset by gains on undisturbed reefs for more than a decade, despite numerous cyclones and periods of record heat stress, until three unusually intense cyclones over 5 years drove coral cover to record lows over {\textgreater}1500 km. Ecological damage was particularly severe in the central-southern region where 68{\%} of coral cover was destroyed over {\textgreater}1000 km, forcing record declines in the species richness and abundance of associated fish communities, with many local extirpations. Four years later, recovery of average coral cover was relatively slow and there were further declines in fish species richness and abundance. Slow recovery of community diversity appears likely from such a degraded starting point. Highly unusual characteristics of two of the cyclones, aside from high intensity, inflated the extent of severe ecological damage that would more typically have occurred over 100s of km.

The projected solar brightening is consistent among different future periods and pathways. However, RCMs in North American Coordinated Regional Climate Downscaling Experiment (NA-CORDEX) and convection-permitting simulations of the climate of North America exhibit a significant decrease in surface solar radiation over large areas of the US. Those conflicting responses between the GCMs and RCMs are evident throughout the year with the greatest disagreement during fall. When scrutinizing the mechanism of solar radiation changes, we find that cloud behavior alone cannot adequately explain the contrasting changes in solar radiation. Instead, if a climate model considers transient aerosols is the key for solar brightening or dimming. Future solar brightening is mainly associated with the declining aerosols that have been implemented in most of the CMIP5 GCMs. In contrast, solar dimming becomes evident because of the greenhouse gas effects in those GCMs and RCMs without considering the aerosol effects.

With the continuing rise in earth's surface temperature alongside the world's aging population, research on the mortality burden of heatwave for the older population remains relatively sparse. The potential magnitude of benefits of averting such deaths may be considerable. Objectives: This paper examined the short-term mortality displacement (or “harvesting”) of heatwave, characterized the heatwave-mortality relationship, and estimated death burden and health costs attributable to heatwave among the elderly in Australia. Methods: We collected daily data on the temperature and deaths of people aged ≥75 years in the five largest cities of Australia (Sydney, Melbourne, Brisbane, Perth and Adelaide), totaling 368,767 deaths in different periods between 1988 and 2011. A total of 15-tiered heatwave definitions, based on intensity (95th to 99th percentiles of temperature distribution) and duration (two or more consecutive days), were used to quantify heatwave effects, using time-series regression and random-effects meta-analysis. We calculated attributable deaths for each city and by different types of heatwave. Potential economic benefits in monetary terms were also estimated, considering that heat-related deaths are avoidable. Results: Among the Australian elderly population, we found significant associations between heatwave and deaths, with raised mortality immediately in the first few days followed by lower-than-expected mortality. In general, heatwave was associated with an average death increase of 28{\%} (95{\%} confidence interval: 15{\%} to 42{\%}), and greater increases were mostly observed for more intense heatwaves across multiple megacities. During the study period, there were dozens to hundreds of deaths attributable to heatwave for each city, equating to an economic loss of several million Australian dollars every year. Although the estimated attributable deaths varied by heatwave intensity and duration, the pattern was not consistent across cities. Conclusions: Heatwave caused harvesting effects on mortality in the elderly population of Australia, and contributed to a substantial amount of death burden and indirect financial costs. To lessen the health impacts of heatwave in the affected regions, effective heatwave early warning systems and interventions targeted at the elderly population could be beneficial, both now and in the future.}, author = {Cheng, Jian and Xu, Zhiwei and Bambrick, Hilary and Su, Hong and Tong, Shilu and Hu, Wenbiao}, doi = {10.1016/j.envint.2018.03.041}, isbn = {1873-6750 0160-4120}, issn = {01604120}, journal = {Environment International}, keywords = {Australia,Burden,Elderly,Heatwave,Mortality}, month = {jun}, pages = {334--342}, title = {{Heatwave and elderly mortality: An evaluation of death burden and health costs considering short-term mortality displacement}}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0160412017321980}, volume = {115}, year = {2018} } @article{Cheong2018, abstract = {{\textcopyright} 2018 Royal Meteorological Society.

Trends in a range of climate extremes indices were assessed focusing on spatial variation in these trends. For most locations temperature trends obtained in this study appear broadly consistent with previous assessments; for some locations stronger trends have been detected through the inclusion of new data. In contrast to earlier studies, evidence of trends in precipitation extremes is emerging, with significant increasing trends in both regional and subregional data. In addition, large correlations between regional rainfall extremes and large-scale features such as El Ni{\~{n}}o-Southern Oscillation and the Indian Ocean Dipole were identified. Finally, the observed trends are compared with a regional climate model reconstruction of the historical period.

Relative Concentration Pathway 8.5 was used to project precipitation derived from daily gridded weather observation data ({\~{}} 6 × 10 km resolution) covering the central of three adjacent watersheds serving metropolitan Vancouver for the 2020s, 2040s, 2060s and 2080s. Results: Precipitation is predicted to steadily increase in these watersheds during the wet season (Oct.-Mar.) and decrease in other parts of the year up through the 2080s. More weeks with extreme rain ({\textgreater}90th percentile) are expected. These weeks are predicted to increase the annual rates of cryptosporidiosis and giardiasis by approximately 16{\%} by the 2080s corresponding to an increase of 55-136 additional cases per year depending upon the climate model used. The predicted increase in the number of waterborne illness cases are during the wet months. The range in future projections compared to historical monthly case counts typically differed by 10-20{\%} across climate models but the direction of change was consistent for all models. Discussion: If new water filtration measures had not been implemented in our study area in 2010-2015, the risk of cryptosporidiosis and giardiasis would have been expected to increase with climate change, particularly precipitation changes. In addition to the predicted increase in the frequency and intensity of extreme precipitation events, the frequency and length of wet and dry spells could also affect the risk of waterborne diseases as we observed in the historical period. These findings add to the growing evidence regarding the need to prepare water systems to manage and become resilient to climate change-related health risks.}, author = {Chhetri, Bimal K. and Galanis, Eleni and Sobie, Stephen and Brubacher, Jordan and Balshaw, Robert and Otterstatter, Michael and Mak, Sunny and Lem, Marcus and Lysyshyn, Mark and Murdock, Trevor and Fleury, Manon and Zickfeld, Kirsten and Zubel, Mark and Clarkson, Len and Takaro, Tim K.}, doi = {10.1186/s12940-019-0550-y}, issn = {1476069X}, journal = {Environmental Health}, keywords = {Climate change,Downscaled climate projections,Extreme precipitation,Future health impact,Waterborne disease}, month = {dec}, number = {1}, pages = {116}, pmid = {31888648}, publisher = {BioMed Central Ltd.}, title = {{Projected local rain events due to climate change and the impacts on waterborne diseases in Vancouver, British Columbia, Canada}}, url = {https://ehjournal.biomedcentral.com/articles/10.1186/s12940-019-0550-y}, volume = {18}, year = {2019} } @inproceedings{Chiew2017, address = {Hobart, TAS, Australia}, author = {Chiew, F.

The network is predominantly focused on freight traffic with the exception of key passenger corridors along the eastern seaboard and in the upper Midwest. This extensive rail network enhances connectivity, but also raises the question of potential vulnerability to climate changes over the next century. Specifically, projected changes in temperature highlight the vulnerability of tracks to temperature increases and the accompanying issue of track expansion, which under current operating policies can lead to train delays, and in the most extreme cases can lead to derailments. In this study, the issue of potential impacts to the rail network are analyzed in terms of the cost of potential increases in delays that will occur due to responses of train network operators to temperature increases. Impacts analyzed using a range of climate models indicate that the rail network may incur an increase in delay-minute costs over typical historic costs of between {\$}25 and {\$}45 billion cumulatively through 2100 under a low greenhouse gas emissions future, and between {\$}35 and {\$}60 billion under a high emission scenario.

To this end, we investigated microclimate differences within an urban park (the Singapore Botanic Gardens) to assess if variations in plot-scale land cover affect both objective (measured) and subjective (surveyed) microclimate data. Over two monsoonal seasons, we obtained data from four distinct sites-a tropical rainforest stand, a palm tree valley, a water-body feature, and the park visitors' centre. Measured climate data (e.g. air temperature, vapour pressure, wind velocity and globe temperatures) were used to derive mean radiant temperature Tmrt and three thermal comfort indices (e.g. temperature-humidity index THI, physiological equivalent temperature PET, and wet-bulb globe temperature WBGT). Concurrent to these measurements, we also surveyed park users (n = 1573) for perceived microclimate sensations and preferences in thermal, humidity, wind and sun exposure, as well as their overall assessment of climate comfort/discomfort. The results indicate significant differences in both measured and perceived microclimates over different sites and seasons, with (i) selected heat stress thresholds based on thermal comfort indices exceeded at several sites, and (ii) visitors perceived generally hot, humid and low-wind conditions throughout. Variations in respondent acclimatisation to tropical climates are observed between correlations of WBGT and some sensation votes, with apparently stronger correlations with more acclimated respondents. While humidity was voted as the most uncomfortable climate variable across all sites, a large majority of respondents felt comfortable climate conditions throughout. Present results confirm that vegetation canopy characteristics affecting wind and sun exposure appear to be important factors in outdoor thermal comfort.

The main tool for assessing landslide risk relies on rainfall thresholds and thus, many countries established early warning systems aimed to landslide hazard assessment. The Umbria Region Civil Protection Centre developed an operational early warning system for landslide risk assessment, named PRESSCA, based on the soil saturation conditions to identify rainfall thresholds. These thresholds, currently used by the Civil Protection operators for the day-by-day landslide hazard assessment, provided satisfactory results with more than 86{\%} of the landslides events correctly identified during the period 1990–2013. In this study, the PRESSCA system was employed for the assessment of climate change impact on landslide hazard in Central Italy. The outputs of five different Global Circulation Models (GCMs) were downscaled and weather generators were used for obtaining hourly rainfall and temperature time series from daily GCMs projection. Then, PRESSCA system was employed to estimate the number of landslide occurrence per year. By comparing results obtained for three different periods (1990–2013 (baseline), 2040–2069 and 2070–2099), for the Umbria territory a general increase in events occurrence was expected (up to more than 40{\%}) in the future period, mainly during the winter season. The results also revealed that the effect of climate change on landslides was not straightforward to identify and the close interaction between rainfall magnitude/intensity, temperature and soil moisture should be analysed in depth. Overall, soil moisture was projected to decrease throughout the year but during the wet season the variations with respect to the present period were very small. Specifically, it was found that during the warm-dry season, due to the strong decrease of soil moisture, even for a sensible increase in rainfall intensity, the landslide occurrence was unchanged. Conversely, during the cold-wet season, the number of landslide events increased considerably if a positive variation in rainfall amount, more significant than rainfall intensity, was coupled with small negative variations in soil moisture.}, author = {Ciabatta, L. and Camici, S. and Brocca, L. and Ponziani, F. and Stelluti, M. and Berni, N. and Moramarco, T.}, doi = {10.1016/j.jhydrol.2016.02.007}, issn = {00221694}, journal = {Journal of Hydrology}, keywords = {Climate change,Early warning system,Landslide,Rainfall,Soil moisture}, month = {oct}, pages = {285--295}, publisher = {Elsevier B.V.}, title = {{Assessing the impact of climate-change scenarios on landslide occurrence in Umbria Region, Italy}}, volume = {541}, year = {2016} } @article{Ciais2005a, author = {Ciais, Ph. and Reichstein, M and Viovy, N and Granier, A and Og{\'{e}}e, J and Allard, V and Aubinet, M and Buchmann, N and Bernhofer, Chr. and Carrara, A and Chevallier, F and {De Noblet}, N and Friend, A D and Friedlingstein, P and Gr{\"{u}}nwald, T and Heinesch, B and Keronen, P and Knohl, A and Krinner, G and Loustau, D and Manca, G and Matteucci, G and Miglietta, F and Ourcival, J M and Papale, D and Pilegaard, K and Rambal, S and Seufert, G and Soussana, J F and Sanz, M J and Schulze, E D and Vesala, T and Valentini, R}, doi = {10.1038/nature03972}, issn = {0028-0836}, journal = {Nature}, month = {sep}, number = {7058}, pages = {529--533}, publisher = {Nature Publishing Group}, title = {{Europe-wide reduction in primary productivity caused by the heat and drought in 2003}}, url = {http://dx.doi.org/10.1038/nature03972 http://10.0.4.14/nature03972 https://www.nature.com/articles/nature03972{\#}supplementary-information http://www.nature.com/articles/nature03972}, volume = {437}, year = {2005} } @article{Cinco2016, abstract = {An analysis of tropical cyclone (TC) data from 1951 to 2013 in the Philippines revealed that an average of 19.4 TCs enter the Philippine Area of Responsibility (PAR) every year and nine TCs cross the country.

We provide quantitative estimates of potential changes in the number of prescribed burning days in coastal NSW in south-eastern Australia, a fire-prone area dominated by dry sclerophyll forests. Burning days are calculated from an objectively designed regional climate model ensemble using three definitions of suitable weather conditions based on: a literature search (Literature), actual weather observed during recorded prescribed burns (Observed) and operational guidelines (Operational). Contrary to some claims, evidence for a decrease in prescribed burning days under projected future climates is weak. We found a complex pattern of changes, with the potential for substantial and widespread increases in the current burning seasons of autumn (March-May) and spring (August-October). Projected changes were particularly uncertain in northern NSW, spanning substantial increases and decreases during autumn. The magnitude of projected changes in the frequency of burning days was highly sensitive to which definition of suitable weather conditions was used, with a relatively small change for the Operational definition (+0.3 to +1.9 days per year across the study area) and larger ranges for the Observed (+0.2 to +7.9 days) and Literature (+1.7 to +6.2 days) definitions. Interannual variability in the number of burning days is projected to increase slightly under projected climate change.

For each stream, flow was separated into direct run‐off and baseflow and high‐ and low‐flow statistics (i.e., Q10 and Q90) with ecologically important hydrologic indices (e.g., frequency of flooding and low flow duration) derived. Using Mann–Kendall tests with a running trend analysis, we determined the persistence of streamflow trends through time. We analysed native stream fauna from {\~{}}400 sites, sampled from 1992 to 2007, to assess species richness among islands and streams. Declines in streamflow metrics indicated a general drying across the islands. In particular, significant declines in low flow conditions (baseflows), were experienced in 57{\%} of streams, compared with a significant decline in storm flow conditions for 22{\%} of streams. The running trend analysis indicated that many of the significant downward trends were not persistent through time but were only significant if recent decades (1987–2016) were included, with an average decline in baseflow and run‐off of 10.90{\%} and 8.28{\%} per decade, respectively. Streams that supported higher native species diversity were associated with moderate discharge and baseflow index, short duration of low flows, and negligible downward trends in flow.

A search of available earthquake catalogs revealed that none of the avalanches were triggered by earthquakes. Analyses of rock-avalanche magnitude, mobility, and frequency reveal a cluster of large (areas ranging from 5.5 to 22.2 km2), highly mobile (height/length OpenSPiltSPi 0.3) rock avalanches that occurred from June 2012 through June 2016 (near the end of the 33-year period of record). These rock avalanches began about 2 years after the long-term trend in mean annual maximum air temperature may have exceeded 0 °C. Possibly more important, most of these rock avalanches occurred during a multiple-year period of record-breaking warm winter and spring air temperatures. These observations suggested to us that rock avalanches in the study area may be becoming larger because of rock-permafrost degradation.

We project that by 2080 the relative frequency of present-day extreme wet bulb temperature events could rise by a factor of 100–250 (approximately double the frequency change projected for temperature alone) in the tropics and parts of the mid-latitudes, areas which are projected to contain approximately half the world's population. In addition, population exposure to wet bulb temperatures that exceed recent deadly heat waves may increase by a factor of five to ten, with 150–750 million person-days of exposure to wet bulb temperatures above those seen in today's most severe heat waves by 2070–2080. Under RCP 8.5, exposure to wet bulb temperatures above 35 °C—the theoretical limit for human tolerance—could exceed a million person-days per year by 2080. Limiting emissions to follow RCP 4.5 entirely eliminates exposure to that extreme threshold. Some of the most affected regions, especially Northeast India and coastal West Africa, currently have scarce cooling infrastructure, relatively low adaptive capacity, and rapidly growing populations.

Here we: (1) propose the concept of 'frigid winter' to address longstanding problems with traditional delineations of winter; and (2) define frigid winter as a period of sustained temperatures below freezing and snow accumulation that together regulate ecological processes and their services.

We use a 20-member ensemble of the GISS climate model to investigate the drought impacts of a repetition of the mid-twentieth-century SST anomalies in a significantly warmer world. Using observed SSTs and mid-twentieth-century forcings (Hist-DRGHT), the ensemble reproduces the observed precipitation deficits during the cold season (October–March) across the Southwest, southern plains, and Mexico and during the warm season (April–September) in the southern plains and the Southeast. Under analogous SST forcing and enhanced warming (Fut-DRGHT,'3 K above preindustrial), cold season precipitation deficits are ameliorated in the Southwest and southern plains and intensified in the Southeast, whereas during the warm season precipitation deficits are enhanced across North America. This occurs primarily from greenhouse gas–forced trends in mean precipitation, rather than changes in SST teleconnections. Cold season runoff deficits in Fut-DRGHT are significantly amplified over the Southeast, but otherwise similar to Hist-DRGHT over the Southwest and southern plains. In the warm season, however, runoff and soil moisture deficits during Fut-DRGHT are significantly amplified across the southern United States, a consequence of enhanced precipitation deficits and increased evaporative losses due to warming.

Glaciers of the Bolivian Andes represent an important water resource for Andean cities and mountain communities, yet relatively little work has assessed changes in their extent over recent decades. In many mountain regions, glacier recession has been accompanied by the development of proglacial lakes, which can pose a glacial lake outburst flood (GLOF) hazard. However, no studies have assessed the development of such lakes in Bolivia despite recent GLOF incidents here. Our mapping from satellite imagery reveals an overall areal shrinkage of 228.1 ± 22.8 km2 (43.1 {\%}) across the Bolivian Cordillera Oriental between 1986 and 2014. Shrinkage was greatest in the Tres Cruces region (47.3 {\%}), followed by the Cordillera Apolobamba (43.1 {\%}) and Cordillera Real (41.9 {\%}). A growing number of proglacial lakes have developed as glaciers have receded, in accordance with trends in most other deglaciating mountain ranges, although the number of ice-contact lakes has decreased. The reasons for this are unclear, but the pattern of lake change has varied significantly throughout the study period, suggesting that monitoring of future lake development is required as ice continues to recede. Ultimately, we use our 2014 database of proglacial lakes to assess GLOF risk across the Bolivian Andes. We identify 25 lakes that pose a potential GLOF threat to downstream communities and infrastructure.

The multimodel ensemble shows robust drying in the mean state across many regions and metrics by the end of the 21st century, even following the more aggressive mitigation pathways (SSP1-2.6 and SSP2-4.5). Regional hotspots with strong drying include western North America, Central America, Europe and the Mediterranean, the Amazon, southern Africa, China, Southeast Asia, and Australia. Compared to SSP3-7.0 and SSP5-8.5, however, the severity of drying in the lower warming scenarios is substantially reduced and further precipitation declines in many regions are avoided. Along with drying in the mean state, the risk of the historically most extreme drought events also increases with warming, by 200–300{\%} in some regions. Soil moisture and runoff drying in CMIP6 is more robust, spatially extensive, and severe than precipitation, indicating an important role for other temperature-sensitive drought processes, including evapotranspiration and snow. Given the similarity in drought responses between CMIP5 and CMIP6, we speculate that both generations of models are subject to similar uncertainties, including vegetation processes, model representations of precipitation, and the degree to which model responses to warming are consistent with observations.

The CMIP6 ensemble shows the largest signals, both for temperature and precipitation, along with the largest inter-model spread. There is a high model consensus across the ensembles on an increase of extreme precipitation and drought frequency in the Mediterranean region. Extreme temperature indices show an increase of heat extremes and a decrease of cold extremes, with CMIP6 showing the highest values and EURO-CORDEX the finest spatial details.

Using these data we generalize site-specific studies to show that that GEV parameters typically scale robustly with event duration (r 2 {\textgreater} 0.88). Thus, we propose a universal IDF formula that allows estimates of rainfall intensity for a continuous range of durations (PXR-4). This parameter scaling property opens the door to estimating sub-daily IDF from daily records. We evaluate this characteristic for selected global cities and a high-density rain gauge network in the United Kingdom. We find that intensities estimated with PXR-4 are within +20{\%} of PXR-2 for durations ranging between 2 and 360 h.

Cultivation is economically significant and growing quickly. However, current understanding of vulnerability for this, and other primary sector activities in New Zealand, makes almost exclusive use of linear outcome-oriented frameworks. Drawing on in-depth, semi-structured interviews with kiwifruit growers and orchard managers, workshops and analysis of secondary data, a “bottom-up” contextual assessment of vulnerability was developed and empirically applied. The findings suggest that climate and markets are the main sources of exposure for growers, with sensitivity moderated by location. Growers employ mostly short-term, reactive adaptive strategies to manage climate exposure and sensitivity, but have less capacity to respond to market-related stressors. Warmer and drier conditions are likely to have adverse effects for kiwifruit production and compound existing vulnerabilities. An ageing population and other processes of rural change may also constrain future adaptation. In order to realise opportunities and minimise losses, longer-term strategic responses are required. The paper demonstrates the need to move beyond outcome-oriented and model-based vulnerability assessments in New Zealand, to consider the broad range of the factors that contribute to vulnerability in the nation's agricultural sectors.

Using minimum temperature data from the 112 observation locations making up the Australian Climate Observations Reference Network – Surface Air Temperature (ACORN-SAT) data set, as well as the Scientific Information for Land Owners (SILO) minimum temperature gridded data surface, we analyse and map trends in extreme minimum temperature indices across southern Australia at seasonal, annual and multi-decadal timeframes since 1960. Our analyses highlights that across southern Australia, despite a warming trend of 0.17 °C per decade since 1960 in the mean annual minimum temperature, there exist regions of localised cooling as well as a much broader spatially-coherent pattern of increasing “frost season” length. Our analysis identifies that the “frost season length” has, across the whole southern portion of Australia, increased on average by 26 days (at 2014) compared with the 1960 to 1990 long term mean. Some areas of south eastern Australia now experience their last frost an average four weeks later than in the 1960s (i.e. mean date of last frost for the period 1960 to 1970 was 19 September versus 23 October for the period 2000 to 2014). Over isolated portions of southern Australia (i.e. northern Victoria and southern New South Wales), the annual frequency of frost events occurring after August has increased by as much as 4 events per year over the last decade, with localised increases in the occurrence of consecutive frost days also observed.

The relevance of dust storms to public health is likely to increase as extreme weather events are predicted to become more frequent with anticipated changes in climate through the 21st century. OBJECTIVES We examined the association between dust storms and county-level non-accidental mortality in the United States from 1993 through 2005. METHODS Dust storm incidence data, including date and approximate location, are taken from the U.S. National Weather Service storm database. County-level mortality data for the years 1993-2005 were acquired from the National Center for Health Statistics. Distributed lag conditional logistic regression models under a time-stratified case-crossover design were used to study the relationship between dust storms and daily mortality counts over the whole United States and in Arizona and California specifically. End points included total non-accidental mortality and three mortality subgroups (cardiovascular, respiratory, and other non-accidental). RESULTS We estimated that for the United States as a whole, total non-accidental mortality increased by 7.4{\%} (95{\%} CI: 1.6, 13.5; p = 0.011) and 6.7{\%} (95{\%} CI: 1.1, 12.6; p = 0.018) at 2- and 3-day lags, respectively, and by an average of 2.7{\%} (95{\%} CI: 0.4, 5.1; p = 0.023) over lags 0-5 compared with referent days. Significant associations with non-accidental mortality were estimated for California (lag 2 and 0-5 day) and Arizona (lag 3), for cardiovascular mortality in the United States (lag 2) and Arizona (lag 3), and for other non-accidental mortality in California (lags 1-3 and 0-5).

This paper examines the theoretical and empirical bases for this assertion. It identifies the mechanisms by which climate can induce landsliding and examines the manner in which these mechanisms may respond to changes in a range of climatic parameters. It is argued that inherent limiting stability factors, which vary with different terrain conditions and landslide types, ultimately govern the nature of response to changing climate. Several modelling approaches are evaluated on the basis of their potential to predict landslide response to climate projections. Given reliable input data of appropriate form and resolution, the existing slope stability, hydrological, and statistical models are for the most part capable of yielding useful prognoses on occurrence, reactivation, magnitude and frequency of landsliding. While there is a strong theoretical basis for increased landslide activity as a result of predicted climate change, there remains a high level of uncertainty resulting from the margins of error inherent in scenario-driven global climate predictions, and the lack of sufficient spatial resolution of currently available downscaled projections. Examples from New Zealand are used to illustrate the extent to which changes resulting from human activity have affected slope stability.

The example of flooding in Atlasville, Ekurhuleni (South Africa) is used to make a case for the usefulness of transdisciplinary approaches. Understanding and responding to local flooding episodes is explored through comparing two hypothetical methodological frameworks-a divided and a united approach. The divided (disciplinary) approach, based on typical disaster response patterns, separated investigations into environmental, government and social factors. In contrast, the united approach, based on a transdisciplinary model, investigated the flooding context along non-traditional lines including: drivers; absorptive and adaptive capacity; and mitigation and preparation. The research highlights that reframing the flooding problem along transdisciplinary lines forces researchers to analyse the context more comprehensively as isolated analyses are unable to determine or consider the cumulative impacts of individual phenomena.

In addition, it is necessary to analyze changes of river flow regimes, i.e.changes in the temporal dynamics of river discharge, as these are important for the well-being of humans (e.g.with respect to water supply) and freshwater-dependent biota (e.g.with respect to habitat availability). Therefore, we investigated, in a global-scale hydrological modeling study, the relation between climate-induced changes of MAR and changes of a number of river flow regime indicators, including mean river discharge, statistical low and high flows, and mean seasonal discharge. In addition, we identified, for the first time at the global scale, where flow regime shifts from perennial to intermittent flow regimes (or vice versa) may occur due to climate change. Climate-induced changes of all considered river flow regime indicators (except seasonal river flow changes) broadly follow the spatial pattern of MAR changes. The differences among the computed changes of MAR due to the application of the two climate models are larger than the differences between the change of MAR and the change of the diverse river flow indicators for one climate model. At the sub-basin and grid cell scales, however, there are significant differences between the changes of MAR, mean annual river discharge, and low and high flows. Low flows are projected to be more than halved by the 2050s in almost twice the area as compared to MAR. Similarly, northern hemisphere summer flows decrease more strongly than MAR. Differences between the high emissions scenario A2 (with emissions of 25GtCyr 1 in the 2050s) and the low emissions scenario B2 (16GtCyr 1 ) are generally small as compared to the differences due to the two climate models. The benefits of avoided emissions are, however, significant in those areas where flows are projected to be more than halved due to climate change. If emissions were constrained to the B2 scenario, the area with ecologically relevant flow regime shifts would be reduced to 5.4{\%}6.7{\%} of the global land area as compared to 6.3{\%}7.0{\%} in A2.

However, the linkage between precipitation patterns and streamflow characteristics are poorly understood, especially in small rivers. We analysed the temporal trends of temperature, precipitation, and extreme indices of wet and dry spells in the Rosi watershed in Central Nepal, and observed the temporal patterns of the streamflow of the Rosi river. We also examined the linkages between the average and extreme climate indices and streamflow. We found that the area has warmed up by an average of 0.03 °C/year, and has seen a significant decline in precipitation. The dry spell as represented by the maximum length of the dry spell (CDD) and the magnitude of dryness (AII) has become more pronounced, while the wet spell as represented by the number of heavy rainfall days (R5D) and the precipitation intensity on wet days (SDII) has diminished significantly. Our analysis shows that recent changes in precipitation patterns have affected the streamflow of the Rosi river, as manifested in the observed decline in annual and seasonal streamflows.

With the Intermediate-High and Highest sea level rise scenarios, 489 and 668 communities, respectively, would face effective inundation by the year 2100.

In close collaboration with tourism stakeholders and CS providers, we explored main barriers hampering the actual use and effectiveness of climate services and identified potential drivers to support further product development and widespread uptake of CS. Despite the high vulnerability of tourism to climate variability and change, the actual use of CS among Austrian tourism stakeholders is rather limited. The main barriers to the use of CS in tourism include wide-spread low levels of risk awareness, a certain degree of risk denial, a lacking sense of urgency due to (yet still) little financial pressure, and rather short business decision cycles, which lead to a low prioritization of climate issues. Furthermore, lack of knowledge of existing services and their benefits, lack of applicability, and distrust in climate services restrict their use. Recommendations for an enhanced uptake of CS thus include the improved demonstration and communication of their added value.

As an indicator of flood hazard we looked at changes in the 30-y return level of 5-d average peak flows under representative concentration pathway RCP8.5 at the end of this century. Not everywhere does climate change result in an increase in flood hazard: decreases in the magnitude and frequency of the 30-y return level of river flow occur at roughly one-third (20-45{\%}) of the global land grid points, particularly in areas where the hydrograph is dominated by the snowmelt flood peak in spring. In most model experiments, however, an increase in flooding frequency was found in more than half of the grid points. The current 30-y flood peak is projected to occur in more than 1 in 5 y across 5-30{\%} of land grid points.

To assess their future evolution in the Mediterranean Sea we use, for the first time, a dedicated ensemble of fully-coupled Regional Climate System Models from the Med-CORDEX initiative and a multi-scenario approach. The models appear to simulate well MHW properties during historical period, despite biases in mean and extreme SST. In response to increasing greenhouse gas forcing, the events become stronger and more intense under RCP4.5 and RCP8.5 than RCP2.6. By 2100 and under RCP8.5, simulations project at least one long-lasting MHW every year, up to three months longer, about 4 times more intense and 42 times more severe than present-day events. They are expected to occur from June-October and to affect at peak the entire basin. Their evolution is found to occur mainly due to an increase in the mean SST, but increased daily SST variability also plays a noticeable role. Until the mid-21st century, MHW characteristics rise independently of the choice of the emission scenario, the influence of which becomes more evident by the end of the period.

Freeze damage to blossoms was assessed using a sequential model.

Critical temperatures for each stage were obtained from the literature and used to identify the occurrence freeze injury based on minimum temperature occurrence. In New York, temperature variance was the dominant climatological factor controlling freeze risk. A small {\textless}5{\%} increase in variance counteracted mean temperature increases of up to 5.5 °C leading to increased freeze risk despite warming temperatures. In other apple-growing regions in the northwestern and southeastern United States, changes in freeze risk were dominated by changes in mean temperature. This demonstrates that in some regions the risk of freeze injury under future climate conditions may be more sensitive to changes in temperature variance. Variance is currently not well simulated by climate models. Because freeze risk also increases when the chill requirement is reduced, adaptation decisions to transition to lower chill requirement cultivars may be ill-advised in northern climates similar to New York as even the highest chill requirements were satisfied under the conditions with the greatest warming.

Other synoptic patterns conducive to freezing rain include arctic fronts, isentropic lift over an arctic air mass, and cold air damming. Causes of spatial and temporal variations in freezing rain include, but are not limited to, terrain and proximity to water.

Successful forecasting of ice storm events requires evaluation of the thermodynamic profile of the atmosphere. Local effects such as proximity to water and topography must be taken into account, and non-linear processes such as latent heating and cooling must not be ignored. Ice accumulation can cause tree damage, which, in addition to breakage of electrical cables, can lead to power outages.

The results show that the Northern Hemisphere (NH) terrestrial NWS experienced significant ( p {\textless} 0.1) decreasing trends during 1980–2010, when the Southern Hemisphere (SH) ocean NWS was characterized by significant ( p {\textless} 0.1) upward trends. However, during 2010–19, global NWS trends shifted in their sign: NWS trends over the NH land became positive, and trends over the SH tended to be negative. We propose that the strengthening of SH NWS during 1980–2010 was associated with an intensified Hadley cell over the SH, while the declining of NH land NWS could have been caused by changes in atmospheric circulation, alteration of vegetation and/or land use, and the accelerating Arctic warming. The CMIP6 model simulations further demonstrate that the greenhouse gas (GHG) warming plays an important role in triggering the NWS trends over the two hemispheres during 1980–2010 through modulating meridional atmospheric circulation.

Our results project maize to face progressively worse impacts under a range of RCPs but spring wheat and soybean to improve globally through to the 2080s due to CO2 fertilization effects, even though parts of the tropic and sub-tropic regions could face substantial yield declines. We find extreme heat stress at anthesis (HSA) by the 2080s (relative to the 1980s) under RCP 8.5, taking into account CO2 fertilization effects, could double global losses of maize yield ($\Delta$Y = −12.8 ± 6.7{\%} versus − 7.0 ± 5.3{\%} without HSA), reduce projected gains in spring wheat yield by half ($\Delta$Y = 34.3 ± 13.5{\%} versus 72.0 ± 10.9{\%} without HSA) and in soybean yield by a quarter ($\Delta$Y = 15.3 ± 26.5{\%} versus 20.4 ± 22.1{\%} without HSA). The range reflects uncertainty due to differences between climate model scenarios; soybean exhibits both positive and negative impacts, maize is generally negative and spring wheat generally positive. Furthermore, when assuming CO2 fertilization effects to be negligible, we observe drastic climate mitigation policy as in RCP 2.6 could avoid more than 80{\%} of the global average yield losses otherwise expected by the 2080s under RCP 8.5.

For spring and autumn, these robust increases emerge before mean global warming of 2 °C above the preindustrial baseline. We also find that days with high convective available potential energy (CAPE) and strong low-level wind shear increase in occurrence, suggesting an increasing likelihood of atmospheric conditions that contribute to the most severe events, including tornadoes. In contrast, whereas expected decreases in mean wind shear have been used to argue for a negative influence of global warming on severe thunderstorms, we find that decreases in shear are in fact concentrated in days with low CAPE and therefore do not decrease the total occurrence of severe environments. Further, we find that the shift toward high CAPE is most concentrated in days with low convective inhibition, increasing the occurrence of high-CAPE/low-convective inhibition days. The fact that the projected increases in severe environments are robust across a suite of climate models, emerge in response to relatively moderate global warming, and result from robust physical changes suggests that continued increases in greenhouse forcing are likely to increase severe thunderstorm occurrence, thereby increasing the risk of thunderstorm-related damage.}, author = {Diffenbaugh, Noah S and Scherer, Martin and Trapp, Robert J}, doi = {10.1073/pnas.1307758110}, issn = {0027-8424}, journal = {Proceedings of the National Academy of Sciences}, keywords = {CMIP5,GCM,hazards,severe weather}, month = {oct}, number = {41}, pages = {16361--16366}, pmid = {24062439}, publisher = {National Academy of Sciences}, title = {{Robust increases in severe thunderstorm environments in response to greenhouse forcing}}, url = {http://www.ncbi.nlm.nih.gov/pubmed/24062439 http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=PMC3799355 http://www.pnas.org/cgi/doi/10.1073/pnas.1307758110}, volume = {110}, year = {2013} } @article{Dikanski2016, author = {Dikanski, Hristo and Hagen-Zanker, Alex and Imam, Boulent and Avery, Kate}, doi = {10.1680/jensu.15.00021}, issn = {1478-4629}, journal = {Proceedings of the Institution of Civil Engineers – Engineering Sustainability}, month = {jun}, number = {5}, pages = {237--248}, title = {{Climate change impacts on railway structures: bridge scour}}, url = {http://www.icevirtuallibrary.com/doi/10.1680/jensu.15.00021}, volume = {170}, year = {2016} } @article{Diro2014, author = {Diro, G.

At some locations increases in annual number of frost days are observed, while other locations show decreases more consistent with the longer term trend. Assessing monthly trends, we find a consistent increase in frost days at all stations in southeast Australia in late autumn (May). The trends are downwards during the winter months (June, July and August) indicating a decrease in the number of frost days. In early spring (August and September), the sign of the trend varies substantially between stations. Similarly, southwest Western Australia has experienced increases in the monthly number of frost days.

We examine the relationship with the concurrent recent drying since the 1990s in southeast Australia and since the 1970s in southwest Western Australia.

The rogation ceremonies present a seasonal distribution that is related to the crops and to the typical distribution of rainfall over the year. August was the month with most pro serenitate rogations because farmers needed dry conditions for harvest, whereas excess rainfall at this time would lead to rotting and loss of the harvest. The pro pluvia rogations were markedly more frequent during January and February when farmers needed rain for sowing.

Together with local climate-driven invasion and extinction, these processes result in altered community structure and diversity, including possible emergence of novel ecosystems.

Here, a closer look based on multiple precipitation datasets reveals important regional disparities in these changes. Warm-season rainfall increased over both basin areas and mountain ranges during 1961–1998 due to enhanced moisture flux convergence associated with changes in the large-scale circulation and increases in atmospheric moisture content. Despite a significant decrease in warm-season precipitation over the high mountain ranges after the year 1998, warm season rainfall has remained large over low-lying basin areas. This discrepancy, which is also reflected in changes in river flow, soil moisture, and vegetation, primarily results from disparate responses to enhanced warming in the mountain and basin areas of AECA. In addition to changes in the prevailing circulation and moisture transport patterns, the decrease in precipitation over the mountains has occurred mainly because increases in local water vapor saturation capacity (which scales with temperature) have outpaced the available moisture supply, reducing relative humidity and suppressing precipitation. By contrast, rainfall over basin areas has been maintained by accelerated moisture recycling driven by rapid glacier retreat, snow melt, and irrigation expansion.

By taking into account both the statistical significance of the change and the models' agreement on its sign, we identify regions where the projected climate change signal is robust, suggesting confidence that the precipitation characteristics will change, and those where changes in the precipitation statistics are non-significant. Results show that, when spatially averaged, the RCMs median change is usually in agreement with that of the GCMs ensemble: even though the change in seasonal mean precipitation may differ, in some cases, other precipitation characteristics (e.g., intensity, frequency, and duration of dry and wet spells) show the same tendency. When the robust change (i.e., the value of the change averaged only over the land points where it is robust) is compared between the GCMs and RCMs, similarities are striking, indicating that, although with some uncertainty on the geographical extent, GCMs and RCMs project a consistent future. Potential added value of downscaling future climate projections (i.e., non-negligible fine-scale information that is absent in the lower resolution simulations) is found for instance over the Ethiopian highlands, where the RCM ensemble shows a robust decrease in mean precipitation in contrast with the GCMs results. This discrepancy may be associated with the better representation of topographical details that are missing in the large scale GCMs. The impact of the heterogeneity of the GCM–RCM matrix on the results has been also investigated; we found that, for most regions and indices, where results are robust or non-significant, they are so independently on the choice of the RCM or GCM. However, there are cases, especially over Central Africa and parts of West Africa, where results are uncertain, i.e. most of the RCMs project a statistically significant change but they do not agree on its sign.

Here the outputs of an ensemble of high-resolution (0.11°) regional climate models (RCM) from the Coordinated Regional-climate Downscaling Experiment for Europe (EURO-CORDEX) have been bias adjusted, and a number of climate indices from the Expert Team on Climate Change Detection and Indices have been calculated for the present (1981?2010) and future (2071?2100) climate. Indices include absolute-thresholds indices, percentile-based indices, and indices based on the duration of an event. Results show that absolute-threshold indices are largely affected by bias adjustment, as they depend strongly on both the present mean climate value (usually largely biased in the original RCMs) and its shift under climate change. The change of percentile-based indices is less affected by bias adjustment, as that of indices based on the duration of an event (e.g., consecutive dry days or heat waves) although the present climate value can differ between original and bias-adjusted results.

In addition, water demand is growing due to increasing irrigated agriculture, population and hydropower production. In this context, we assess current and future water risks and management options for the Vilcanota-Urubamba basin, Southern Peru. Therefore, the GLOF susceptibility of glacier lakes and the potential maximum reach of damaging flow were analysed. Eighteen out of 134 current and another six out of 20 future glacier lakes were identified as potentially highly susceptible to GLOF. A total of eight existing and one possible future lakes indicate very high risk potentials. Furthermore, a comprehensive surface water balance scheme for five selected subcatchments reveals that future river discharge could be reduced by some 2–11{\%} (7–14{\%}) until 2050 (2100). Particularly in headwaters and during dry seasons, glacier contribution representing roughly 15–25{\%} to total streamflow is crucial and would substantially decrease to below 4–22{\%} (1–3{\%}) until 2050 (2100) with strong glacier shrinkage under intense warming (scenario RCP8.5). In the middle and lower basin, long-term water availability could be jeopardized by growing irrigated agriculture and hydropower capacity. Combining a GLOF and water shortage risk assessment, three key hotspots of current and future water risks were identified. In the context of the identified risks and complex intertwining of water users involving conflict potentials, robust adaptation planning is necessary within an integrative water and risk management framework. Therefore, it is crucial to incorporate ancestral and local knowledge for long-term management planning and implementation.

However, little is known about how many rock glaciers might decay because of global warming and how much this decay might contribute to water and sediment release. We investigated an inventory of {\textgreater}6500 rock glaciers in the Argentinian Andes, spanning the climatic gradient from the Desert Andes to cold-temperate Tierra del Fuego. We used active rock glaciers as a diagnostic of permafrost, assuming that the toes mark the 0 °C isotherm in climate scenarios for the twenty-first century and their impact on freezing conditions near the rock glacier toes. We find that, under future worst case warming, up to 95{\%} of rock glaciers in the southern Desert Andes and in the Central Andes will rest in areas above 0 °C and that this freezing level might move up more than twice as much ({\~{}}500 m) as during the entire Holocene ({\~{}}200 m). Many active rock glaciers are already well below the current freezing level and exemplify how local controls may confound regional prognoses. A Bayesian Multifactor Analysis of Variance further shows that only in the Central Andes are the toes of active rock glaciers credibly higher than those of inactive ones. Elsewhere in the Andes, active and inactive rock glaciers occupy indistinguishable elevation bands, regardless of aspect, the formation mechanism, or shape of rock glaciers. The state of rock glacier activity predicts differences in elevations of toes to 140 m at best so that regional inference of the distribution of discontinuous permafrost from rock-glacier toes cannot be more accurate than this in the Argentinian Andes.

The lake phenology metrics include seasonal timing and duration of annual ice cover. A moving t test (MTT) algorithm allows for automated lake ice retrievals with daily temporal fidelity and 5 km resolution gridding. The resulting ice phenology record shows strong agreement with available ground-based observations from the Global Lake and River Ice Phenology Database (95.4 {\%} temporal agreement) and favorable correlations (R) with alternative ice phenology records from the Interactive Multisensor Snow and Ice Mapping System (R = 0.84 for water clear of ice (WCI) dates; R = 0.41 for complete freeze over (CFO) dates) and Canadian Ice Service (R = 0.86 for WCI dates; R = 0.69 for CFO dates). Analysis of the resulting 12-year (2002–2015) AMSR-E/2 ice record indicates increasingly shorter ice cover duration for 43 out of 71 (60.6 {\%}) Northern Hemisphere lakes examined, with significant (p  {\textless}  0.05) regional trends toward earlier ice melting for only five lakes. Higher-latitude lakes reveal more widespread and larger trends toward shorter ice cover duration than lower-latitude lakes, consistent with enhanced polar warming.

WSCVD was computed by summing daily streamflow for a seasonal window then calculating the day that half of the seasonal volume had flowed past the gage. We used basins where at least 30 percent of annual precipitation was received as snow, and streamflow data were restricted to regionally based winter-spring periods to focus the analyses on snowmelt-related streamflow. Trends over time in WSCVD at gages in the eastern U.S. were relatively homogenous in magnitude and direction and statistically significant; median WSCVD was earlier by 8.2days (1.1days/decade) and 8.6days (1.6days/decade) for 1940–2014 and 1960–2014 periods respectively. Fewer trends in the West were significant though most trends indicated earlier WSCVD over time. Trends at low-to-mid elevation ({\textless}1600m) basins in the West, predominantly located in the Northwest, had median earlier WSCVD by 6.8days (1940–2014, 0.9days/decade) and 3.4days (1960–2014, 0.6days/decade).

Trends toward earlier WSCVD in the Northwest were not statistically significant, differing from previous studies that observed many large and (or) significant trends in this region.

We used a case study design and participatory and collaborative approach with the community of Nain in northern Labrador, Canada. Focus groups (n = 2), interviews (n = 22), and participant observation were conducted in 2010–11. We found that an appreciation of place was critical for understanding the full range of health influences of sea ice use for Inuit. Negative physical health impacts were reported on less frequently than positive health benefits of sea ice use, which were predominantly related to mental/emotional, spiritual, social, and cultural health. We found that sea ice means freedom for sea ice users, which we suggest influences individual and collective health through relationships between sea ice use, culture, knowledge, and autonomy. While sea ice users reported increases in negative physical health impacts such as injuries and stress related to changing environmental conditions, we suggest that less tangible climate change impacts related to losses of health benefits and disruptions to place meanings and place attachment may be even more significant. Our findings indicate that climate change is resulting in and compounding existing environmental dispossession for Inuit.

The 1983 tropical cyclones had contrasting impacts, depending on the shoreline indicator considered. While they generally caused a marked retreat of the stability line, the base of the beach advanced at some locations, as a result of either sediment reworking or fresh sediment inputs. The post-cyclone fair weather period was characterised by reversed trends indicating island morphological readjustment. Cyclonic waves contributed to island upwards growth, which reached up to 1m in places, through the transfer of sediments up onto the island surface. However, the steep outer slopes of atolls limited sediment transfers to the reef flat and island system. We found that 57{\%} of the study islands are disturbed by human activities, including ‘rural' and uninhabited islands.

Due to current climatic change and the ensuing permafrost degradation, the vulnerability of these infrastructures to destabilization may increase. Therefore, there is a real potential for instabilities to develop on ropeway transport systems in the Alps, requiring a better understanding of these processes. This study investigates the relation between permafrost and infrastructure stability in the French Alps, seeking to understand the evolution of this phenomenon over the past decades. This was done by following a two-step analysis. At first, the infrastructure elements built on modeled permafrost-affected areas were inventoried at the scale of the French Alps in order to get an overview of the possible vulnerabilities. Then, our study presents a detailed historical inventory of damage to infrastructure over the past three decades in different geomorphologic contexts. Overall, in the French Alps, there are almost 1000 infrastructure elements located in permafrost areas among which 12 (i.e., 24 infrastructure elements) were identified to have been subject to repeated instances of disruption and deterioration and most of the damages recorded were in areas where permafrost degradation is fully expected (ice-rich terrain).

Models were generally able to capture the broad features in reanalyses reported previously: underdispersion/regularity (i.e. variance less than mean) in the western core of the Atlantic storm track surrounded by overdispersion/clustering (i.e. variance greater than mean) to the north and south and over Western Europe. Regression of counts onto North Atlantic Oscillation (NAO) indices revealed that much of the overdispersion in the historical reanalyses and model simulations can be accounted for by NAO variability. Future changes in dispersion were generally found to be small and not consistent across models. The overdispersion statistic, for any 30-year sample, is prone to large amounts of sampling uncertainty which obscures the climate change signal. For example, the projected increase in dispersion for storm counts near London in the CNRMCM5 model is 0.1 compared to a standard deviation of 0.25.

This dengue reemergence has provoked interest in the extent of the future threat posed by the yellow fever mosquito, Aedes (Stegomyia) aegypti (L.), the primary vector of dengue and yellow fever viruses in urban settings, to human health in the continental United States. Ae. aegypti is an intriguing example of a vector species that not only occurs in the southernmost portions of the eastern United States today but also is incriminated as the likely primary vector in historical outbreaks of yellow fever as far north as New York, Philadelphia, and Boston, from the 1690s to the 1820s. For vector species with geographic ranges limited, in part, by low temperature and cool range margins occurring in the southern part of the continental United States, as is currently the case for Ae. aegypti, it is tempting to speculate that climate warming may result in a northward range expansion (similar to that seen for Ixodes tick vectors of Lyme borreliosis spirochetes in Scandinavia and southern Canada in recent decades). Although there is no doubt that climate conditions directly impact many aspects of the life history of Ae. aegypti, this mosquito also is closely linked to the human environment and directly influenced by the availability of water-holding containers for oviposition and larval development. Competition with other container-inhabiting mosquito species, particularly Aedes (Stegomyia) albopictus (Skuse), also may impact the presence and local abundance of Ae. aegypti. Field-based studies that focus solely on the impact of weather or climate factors on the presence and abundance of Ae. aegypti, including assessments of the potential impact of climate warming on the mosquito's future range and abundance, do not consider the potential confounding effects of socioeconomic factors or biological competitors for establishment and proliferation of Ae. aegypti. The results of such studies therefore should not be assumed to apply in areas with different socioeconomic conditions or composition of container-inhabiting mosquito species. For example, results from field-based studies at the high altitude cool margins for Ae. aegypti in Mexico's central highlands or the Andes in South America cannot be assumed to be directly applicable to geographic{\ldots}}, author = {Eisen, Lars and Moore, Chester G}, doi = {10.1603/ME12245}, issn = {0022-2585}, journal = {Journal of Medical Entomology}, month = {may}, number = {3}, pages = {467--478}, pmid = {23802440}, title = {{Aedes (Stegomyia) aegypti in the Continental United States: A Vector at the Cool Margin of Its Geographic Range}}, url = {http://www.ncbi.nlm.nih.gov/pubmed/23802440 https://academic.oup.com/jme/article-lookup/doi/10.1603/ME12245}, volume = {50}, year = {2013} } @article{Ekstrom2018, abstract = {Metrics based on streamflow and/or climate variables are used in water management for monitoring and evaluating available resources.

Predictor variables include moisture transport in the middle atmosphere (700 hPa), vertical temperature gradients, and geopotential height fields of the 1000 and 500 hPa layers. The results allow for the first time to derive a spatially interpolated map with future rainfall change estimates for the main Hawaiian Islands. The statistical downscaling was applied to project wet (November–April) and dry (May–October) season rainfall anomalies for the middle and late 21st century. Overall, the statistical downscaling gives more reliable results for the wet season than for the dry season. The wet‐season results indicate a pronounced dipole structure between windward facing mountain slopes and the leeward side of most of the islands. The climatically wet regions on the windward slopes of the mountain regions are expected to become wetter or remain stable in their seasonal precipitation amounts. On the climatically dry leeward sides of Kaua‘i, O‘ahu, Maui, and Hawai‘i Island, future precipitation exhibits the strongest drying trends.

Meteorological drought is a major natural driving force of desertification and occurs due to the extended periods of low precipitation. Scarcity of water, as well as the excessive use of water resources, mainly for agriculture, creates negative water balances and changes in plant cover, and accelerates desertification. Despite various political measures having been taken in the past, desertification is still a serious environmental problem in many regions in Iran. In this study, drought and aridity indices derived from long-term temperature and precipitation data were used in order to show long-term drought occurrence in different climatic zones in Iran. The results indicated the occurrence of severe and extremely severe meteorological droughts in recent decades in the areas studied. Moreover, the De Martonne Aridity Index (IDM) and precipitation variability index (PVI) showed an ongoing negative trend on the basis of long-term data and the conducted regression analysis.

We do this both through an understanding of the limitations to ozone uptake (i.e. ozone being transferred from some height in the atmosphere to the leaf boundary layer and subsequent uptake via the stomata) as well as through the internal plant processes that will result in the absorbed ozone dose causing damage and/or injury. We consider these processes across a range of scales by which ozone impacts plants, from cellular metabolism influencing leaf level physiology up to whole canopy and root system processes and feedbacks. We explore how these impacts affect leaf level photosynthesis and senescence (and associated carbon assimilation) as well as whole canopy resource acquisition (e.g. water and nutrients) and ultimately crop growth and yield. We consider these processes from the viewpoint of developing crop growth models capable of incorporating key ozone impact processes within modelling structures that assess crop growth under a variety of different abiotic stresses. These models would provide a dynamic assessment of the impact of ozone within the context of other key variables considered important in determining crop growth and yield. We consider the ability to achieve such modelling through an assessment of the different types of crop model currently available (e.g. empirical, radiation use efficiency, and photosynthesis based crop growth models). Finally, we show how international activities such as the AgMIP (Agricultural Modelling and Improvement Intercomparison Project) could see crop growth modellers collaborate to assess the capabilities of different crop models to simulate the effects of ozone and other stresses.

Over these regions, temperatures have been rising at more than twice the global rate of temperature increase. An ensemble of high-resolution downscalings, obtained using a single regional climate model forced with the sea-surface temperatures and sea-ice fields of an ensemble of global circulation model (GCM) simulations, is shown to realistically represent the relatively strong temperature increases observed in subtropical southern and northern Africa. The amplitudes of warming are generally underestimated, however. Further warming is projected to occur during the 21st century, with plausible increases of 4-6 °C over the subtropics and 3-5 °C over the tropics by the end of the century relative to present-day climate under the A2 (a low mitigation) scenario of the Special Report on Emission Scenarios. High impact climate events such as heat-wave days and high fire-danger days are consistently projected to increase drastically in their frequency of occurrence. General decreases in soil-moisture availability are projected, even for regions where increases in rainfall are plausible, due to enhanced levels of evaporation. The regional dowscalings presented here, and recent GCM projections obtained for Africa, indicate that African annual-averaged temperatures may plausibly rise at about 1.5 times the global rate of temperature increase in the subtropics, and at a somewhat lower rate in the tropics. These projected increases although drastic, may be conservative given the model underestimations of observed temperature trends. The relatively strong rate of warming over Africa, in combination with the associated increases in extreme temperature events, may be key factors to consider when interpreting the suitability of global mitigation targets in terms of African climate change and climate change adaptation in Africa.}, author = {Engelbrecht, Francois and Adegoke, Jimmy and Bopape, Mary Jane and Naidoo, Mogesh and Garland, Rebecca and Thatcher, Marcus and McGregor, John and Katzfey, Jack and Werner, Micha and Ichoku, Charles and Gatebe, Charles}, doi = {10.1088/1748-9326/10/8/085004}, issn = {17489326}, journal = {Environmental Research Letters}, keywords = {African temperatures,actionable messages for adaptation,climate change,drought index,heat-waves,high fire-danger days,regional climate model projections}, month = {aug}, number = {8}, pages = {085004}, publisher = {Institute of Physics Publishing}, title = {{Projections of rapidly rising surface temperatures over Africa under low mitigation}}, url = {https://iopscience.iop.org/article/10.1088/1748-9326/10/8/085004 https://iopscience.iop.org/article/10.1088/1748-9326/10/8/085004/meta}, volume = {10}, year = {2015} } @article{England2014, abstract = {Despite ongoing increases in atmospheric greenhouse gases, the Earth's global average surface air temperature has remained more or less steady since 2001. A variety of mechanisms have been proposed to account for this slowdown in surface warming. A key component of the global hiatus that has been identified is cool eastern Pacific sea surface temperature, but it is unclear how the ocean has remained relatively cool there in spite of ongoing increases in radiative forcing. Here we show that a pronounced strengthening in Pacific trade winds over the past two decades - unprecedented in observations/reanalysis data and not captured by climate models - is sufficient to account for the cooling of the tropical Pacific and a substantial slowdown in surface warming through increased subsurface ocean heat uptake. The extra uptake has come about through increased subduction in the Pacific shallow overturning cells, enhancing heat convergence in the equatorial thermocline. At the same time, the accelerated trade winds have increased equatorial upwelling in the central and eastern Pacific, lowering sea surface temperature there, which drives further cooling in other regions. The net effect of these anomalous winds is a cooling in the 2012 global average surface air temperature of 0.1-0.2C, which can account for much of the hiatus in surface warming observed since 2001. This hiatus could persist for much of the present decade if the trade wind trends continue, however rapid warming is expected to resume once the anomalous wind trends abate. {\textcopyright} 2014 Macmillan Publishers Limited.}, author = {England, Matthew H. and Mcgregor, Shayne and Spence, Paul and Meehl, Gerald A. and Timmermann, Axel and Cai, Wenju and Gupta, Alex Sen and Mcphaden, Michael J. and Purich, Ariaan and Santoso, Agus}, doi = {10.1038/nclimate2106}, issn = {17586798}, journal = {Nature Climate Change}, number = {3}, pages = {222--227}, title = {{Recent intensification of wind-driven circulation in the Pacific and the ongoing warming hiatus}}, volume = {4}, year = {2014} } @article{Engram2018, abstract = {Late-winter lake ice regimes are controlled by water depth relative to maximum ice thickness (MIT). When MIT exceeds maximum water depth, lakes freeze to the bottom with bedfast ice (BI) and when MIT is less than maximum water depth lakes have floating ice (FI). Both airborne radar and space-borne synthetic aperture radar (SAR) imagery (Ku-, X-, C-, and L-band) have been used previously to determine whether lakes have a BI or FI regime in a given year, across a number of years, or across large regions. In this study, we use a combination of ERS-1/2, RADARSAT-2, Envisat, and Sentinel-1 SAR imagery for seven lake-rich regions in Arctic Alaska to analyze lake ice regime extents and dynamics over a 25-year period (1992–2016). Our interactive threshold classification method determines a unique statistic-based intensity threshold for each SAR scene, allowing for the comparison of classification results from C-band SAR data acquired with different polarizations and incidence angles. Additionally, our novel method accommodates declining signal strength in aging extended-mission satellite SAR instruments. Comparison of SAR ice regime classifications with extensive field measurements from six years yielded a 93{\%} accuracy. Significant declines in BI regimes were only observed in the Fish Creek area with 3{\%} of lakes exhibiting transitional ice regimes—lakes that switch from BI to FI during this 25-year period. This analysis suggests that the potential conversion from BI to FI regimes is primarily a function of lake depth distributions in addition to regional differences in climate variability. Remote sensing of lake ice regimes with C-band SAR is a useful tool to monitor the associated thermal impacts on permafrost, since lake ice regimes can be used as a proxy for of sub-lake permafrost thaw, considered by the Global Climate Observing System as an Essential Climate Variable (ECV).

The average rate of head decline is ∼0.3 m yr−1, based on time-series data from 79 nested monitoring wells at 18 locations. The consequent compaction of sedimentary layers at these locations is calculated to be causing land subsidence at an average rate of 1.6 cm yr−1. We further measure recent subsidence rates (annual average, 2006–10) throughout the Delta, by analysis of interferometric synthetic aperture radar (InSAR), using 78 ALOS PALSAR interferograms. InSAR-based subsidence rates are 1) consistent with compaction-based rates calculated at monitoring wells, and 2) ∼1–4 cm yr−1 over large (1000s of km2) regions. Ours are the first mapped estimates of Delta-wide land subsidence due to groundwater pumping. If pumping continues at present rates, ∼0.88 m (0.35–1.4 m) of land subsidence is expected by 2050. Anticipated SLR of ∼0.10 m (0.07–0.14 m) by 2050 will compound flood inundation potential.

Several hydrological variables, such as rainfall, terrestrial water storage, and discharge, point out that the unprecedented 2012 flood is mainly related to an early and abundant wet season over the north of the basin. Thus, the peak of the Mara{\~{n}}{\'{o}}n River, the northern contributor of the Amazonas, occurred sooner than usual (in April instead of May), coinciding with the peak of the Ucayali River, the southern contributor. This concomitance caused a dramatic flood downstream in the Peruvian Amazonas. These results are compared to the amplitude and timing of the three most severe extreme floods (1970–2011). The analysis of the climatic features related to the most important floods (1986, 1993, 1999, and 2012) suggests that they are characterized by a La Ni{\~{n}}a event, which originates a geopotential height wave train near the ground, with positive anomalies over the subtropical South and North Pacific and Atlantic and over southeastern South America. These patterns contribute to 1) the origin of an abundant humidity transport flux from the tropical North Atlantic and the Caribbean Sea toward the northwestern Amazon and 2) the maintenance of the monsoon flux over this region. They both favor a strong convergence of humidity in the northern Amazonas basin. Finally, the authors suggest that the intensity of floods is more likely related to an early La Ni{\~{n}}a event (as observed during the 2011/12 season), early rainfall, and simultaneous peaks of both tributaries of the Amazonas River.}, author = {Espinoza, Jhan Carlo and Ronchail, Josyane and Frappart, Fr{\'{e}}d{\'{e}}ric and Lavado, Waldo and Santini, William and Guyot, Jean Loup}, doi = {10.1175/JHM-D-12-0100.1}, issn = {1525-755X}, journal = {Journal of Hydrometeorology}, month = {jun}, number = {3}, pages = {1000--1008}, title = {{The Major Floods in the Amazonas River and Tributaries (Western Amazon Basin) during the 1970–2012 Period: A Focus on the 2012 Flood}}, url = {http://journals.ametsoc.org/doi/10.1175/JHM-D-12-0100.1}, volume = {14}, year = {2013} } @article{Evan2016, author = {Evan, Amato T and Flamant, Cyrille and Gaetani, Marco and Guichard, Fran{\c{c}}oise}, doi = {10.1038/nature17149}, issn = {0028-0836}, journal = {Nature}, month = {mar}, number = {7595}, pages = {493--495}, publisher = {Nature Publishing Group, a division of Macmillan Publishers Limited.

After a long and wide com- munity consultation, a new and more federated structure has been put in place. It consists of three major elements: (1) a handful of common experiments, the DECK (Diagnostic, Evaluation and Characterization of Klima) and CMIP his- torical simulations (1850–near present) that will maintain continuity and help document basic characteristics of mod- els across different phases of CMIP; (2) common standards, coordination, infrastructure, and documentation that will fa- cilitate the distribution of model outputs and the characteriza- tion of the model ensemble; and (3) an ensemble of CMIP- Endorsed Model Intercomparison Projects (MIPs) that will be specific to a particular phase of CMIP (now CMIP6) and that will build on the DECK and CMIP historical simulations to address a large range of specific questions and fill the sci- entific gaps of the previous CMIP phases. The DECK and CMIP historical simulations, together with the use of CMIP data standards, will be the entry cards for models participat- ing in CMIP. Participation in CMIP6-Endorsed MIPs by in- dividual modelling groups will be at their own discretion and will depend on their scientific interests and priorities. With the Grand Science Challenges of theWorld Climate Research Programme (WCRP) as its scientific backdrop, CMIP6 will address three broad questions: – How does the Earth system respond to forcing? – What are the origins and consequences of systematic model biases? – How can we assess future climate changes given inter- nal climate variability, predictability, and uncertainties in scenarios?

Empirical evidence increasingly shows that short episodes of high temperature experienced around flowering can have large negative impacts on cereal grain yields, a phenomenon increasingly referred to as heat stress. Crop models are currently the best tools available to investigate how crops will grow under future climatic conditions, though the need to include heat stress effects has been recognized only relatively recently. We reviewed literature on both how key crop physiological processes and the observed yields under production conditions are impacted by high temperatures occurring particularly in the flowering and grain filling phases for wheat, maize and rice. This state of the art in crop response to heat stress was then contrasted with generic approaches to simulate the impacts of high temperatures in crop growth models. We found that the observed impacts of heat stress on crop yield are the end result of the integration of many processes, not all of which will be affected by a "high temperature" regime. This complexity confirms an important role for crop models in systematizing the effects of high temperatures on many processes under a range of environments and realizations of crop phenology. Four generic approaches to simulate high temperature impacts on yield were identified: (1) empirical reduction of final yield, (2) empirical reduction in daily increment in harvest index, (3) empirical reduction in grain number, and (4) semi-deterministic models of sink and source limitation. Consideration of canopy temperature is suggested as a promising approach to concurrently account for heat and drought stress, which are likely to occur simultaneously. Improving crop models' response to high temperature impacts on cereal yields will require experimental data representative of field production and should be designed to connect what is already known about physiological responses and observed yield impacts.}, author = {{Eyshi Rezaei}, Ehsan and Webber, Heidi and Gaiser, Thomas and Naab, Jesse and Ewert, Frank}, doi = {10.1016/j.eja.2014.10.003}, isbn = {1161-0301}, issn = {11610301}, journal = {European Journal of Agronomy}, keywords = {Cereal yield,Climate change impact,Crop modelling,Heat stress,High temperature}, month = {mar}, pages = {98--113}, title = {{Heat stress in cereals: Mechanisms and modelling}}, url = {http://linkinghub.elsevier.com/retrieve/pii/S1161030114001221 https://linkinghub.elsevier.com/retrieve/pii/S1161030114001221}, volume = {64}, year = {2015} } @article{Fabrega2013, abstract = {This work analyzes hydroclimate projections in Panama toward the end of the 21st century by employing the MRI-AGCM3.1 model.

LMTool was one of several prototype climate services selected for development within EUPORIAS, including those for the UK transport network, food security in Ethiopia, renewable energy production, hydroelectric energy production in Sweden, and river management in two French basins. The LMTool provides SCFs (1–3 months ahead) to farmers in the Southwest UK, alongside 14-day site specific weather forecasts during the winter months when the skill of seasonal forecasts is greatest. We describe the processes through which the LMTool was co-designed and developed with the farmers, its technical development and key features; critically examine the lessons learned and their implications for providing future climate services for land managers; and finally assess the feasibility of delivering an operational winter seasonal climate service for UK land managers. A number of key learning points from developing the prototype may benefit future work in climate services for the land management and agriculture sector; many of these points are also valid for climate services in other sectors. Prototype development strongly benefitted from; working with intermediaries to identify representative, engaged land managers; an iterative and flexible process of co-design with the farmer group; and from an interdisciplinary project team.

Among the numerous strategies to reduce Green House Gas (GHG) emissions is to decommission carbon intensive electricity production while increase the deployment of renewable energy technologies - such as wind and solar power generation. Yet the generation capacity, availability, and intermittency of these renewable energy sources are strongly climate dependent - and may also shift due to unavoidable human-induced change. In this study, we present a method, based on previous studies, that estimates the risk of climate-change on wind and solar resource potential. The assessment combines the risk-based climate projections from the Integrated Global Systems Model (IGSM), which considers emissions and global climate sensitivity uncertainty, with more regionally detailed climate information from 8 GCMs available from the Coupled Model Intercomparison Project phase 3 (CMIP-3). Southern Africa, specifically those in the Southern African Development Countries (SADC), is used as a case study. We find a median change close to zero by 2050 in the long-term mean of both wind speed and Global Horizontal Irradiance (GHI), both used as indicators of changes in electricity production potential. Although the extreme possibilities range from about -15{\%} to +15{\%} change, these are associated with low probability. The most prominent effect of a modest climate mitigation policy is seen in the doubled likelihood of the mode of the distribution of wind power change. This increased likelihood is made at the expense of decreased likelihood in the large changes of the distribution, but these trade-offs with the more extreme likelihoods are not symmetric with respect to the modal change.}, author = {Fant, Charles and {Adam Schlosser}, C. and Strzepek, Kenneth}, doi = {10.1016/j.apenergy.2015.03.042}, issn = {03062619}, journal = {Applied Energy}, keywords = {Climate change,Renewable energy,Solar energy,Southern Africa,Wind energy}, month = {jan}, pages = {556--564}, publisher = {Elsevier Ltd}, title = {{The impact of climate change on wind and solar resources in southern Africa}}, url = {http://linkinghub.elsevier.com/retrieve/pii/S0306261915003268}, volume = {161}, year = {2016} } @article{Fargeon2020, abstract = {Global warming is expected to increase droughts and heatwaves, and consequently fire danger in southern Europe in the forthcoming decades.

The study was conducted using the MaxEnt species distribution model and two data series GFDL-CM3 and MRI-CGCM3 under scenarios RCP2.6 and RCP4.5 of the 5th IPCC report. Our results revealed that elevation, minimum temperature of coldest month, precipitation of coldest quarter, annual mean temperature, and slope aspect, in that order, have the greatest effects on the species' distribution in the study area. Under optimistic scenario RCP2.6, both models predicted that the species' presence area will grow, but under RCP4.5, models predicted that by 2070, some parts of its habitat in western and central heights will be lost because of change in climate parameters like minimum temperature of coldest month and precipitation of coldest quarter. Under the latter scenario, the northeastern parts of the study area showed no changes in terms of climatic parameters and climatic niche. The results of both climate data series indicated that the Juniperus excelsa will slowly migrate to higher elevations to cope with the changing climate.

Here we adapt the multiple linear regression approach to utilize the GO-SHIP Repeat Hydrography data from the northeast Pacific to establish an annually updated relationship between Canth and potential density. This relationship was then used with the NOAA Ocean Acidification Program West Coast Ocean Acidification (WCOA) cruise data sets from 2007, 2011, 2012, and 2013 to determine the spatial variations of Canth in the upwelled water. Our results show large spatial differences in Canth in surface waters along the coast, with the lowest values (37–55 $\mu$mol kg−1) in strong upwelling regions off southern Oregon and northern California and higher values (51–63 $\mu$mol kg−1) to the north and south of this region. Coastal dissolved inorganic carbon concentrations are also elevated due to a natural remineralized component (Cbio), which represents carbon accumulated through net respiration in the seawater that has not yet degassed to the atmosphere. Average surface Canth is almost twice the surface remineralized component. In contrast, Canth is only about one third and one fifth of the remineralized component at 50 m and 100 m depth, respectively. Uptake of Canth has caused the aragonite saturation horizon to shoal by approximately 30–50 m since the preindustrial period so that undersaturated waters are well within the regions of the continental shelf that affect the shell dissolution of living pteropods. Our data show that the most severe biological impacts occur in the nearshore waters, where corrosive waters are closest to the surface.

We show that more tree species have experienced a westward shift (73{\%}) than a poleward shift (62{\%}) in their abundance, a trend that is stronger for saplings than adult trees. The observed shifts are primarily due to the changes of subpopulation abundances in the leading edges and are significantly associated with changes in moisture availability and successional processes.

These discussions have involved widely varying estimates based on drought indices and model-based projections of the future. To investigate and understand the causes for such a disparity between these previous estimates, the authors analyzed the soil moisture at the near-surface soil layer and the entire soil column, as well as the Palmer drought severity index, the Palmer Z index, and the standardized precipitation and evaporation index using the output from the Community Climate System Model, version 4 (CCSM4), and 25 state-of-the-art climate models. These drought indices were computed using potential evapotranspiration estimated by the physically based Penman–Monteith method (PE{\_}pm) and the empirically based Thornthwaite method (PE{\_}th). The results showed that the short-term drought indices are similar to modeled surface soil moisture and show a small but consistent drying trend in the future. The long-term drought indices and the total column soil moisture, however, are consistent in projecting more intense future drought. When normalized, the drought indices with PE{\_}th all show unprecedented future drying, while the drought indices with PE{\_}pm show comparable dryness with the modeled soil moisture. Additionally, the drought indices with PE{\_}pm are closely related to soil moisture during both the twentieth and twenty-first centuries. Overall, the drought indices with PE{\_}pm, as well as the modeled total column soil moisture, suggest a widespread and very significant drying in the Great Plains toward the end of the century. The results suggest that the sharp contrasts about future drought risk in the Great Plains discussed in previous studies are caused by 1) comparing the projected changes in short-term droughts with that of the long-term droughts and/or 2) computing the atmospheric evaporative demand using an empirically based method (e.g., PE{\_}th).

Articles that used measurement and proxy data, reanalyses, regional and global climate model data on past and future trends are evaluated for changes in storm climate. The most important result is that trends in storm activity depend critically on the time period analysed. An increase in storm numbers is evident for the reanalyses period for the most recent decades, whereas most long-term studies show merely decadal variability for the last 100–150 years. Storm trends derived from reanalyses data and climate model data for the past are mostly limited to the last four to six decades. The majority of these studies find increasing storm activity north of about 55–60° N over the North Atlantic with a negative tendency southward. This increase from about the 1970s until the mid-1990s is also mirrored by long-term proxies and the North Atlantic Oscillation and constitutes a part of their decadal variability. Studies based on proxy and measurement data or model studies over the North Atlantic for the past which cover more than 100 years show large decadal variations and either no trend or a decrease in storm numbers. Future scenarios until about the year 2100 indicate mostly an increase in winter storm intensity over the North Atlantic and western Europe.

Many air pollutant sources also emit carbon dioxide (CO2), the dominant anthropogenic greenhouse gas (GHG). The two main contributors to non-attainment of U.S. ambient air quality standards, ozone (O3) and particulate matter (PM), interact with radiation, forcing climate change. PM warms by absorbing sunlight (e.g., black carbon) or cools by scattering sunlight (e.g., sulfates) and interacts with clouds; these radiative and microphysical interactions can induce changes in precipitation and regional circulation patterns. Climate change is expected to degrade air quality in many polluted regions by changing air pollution meteorology (ventilation and dilution), precipitation and other removal processes, and by triggering some amplifying responses in atmospheric chemistry and in anthropogenic and natural sources. Together, these processes shape distributions and extreme episodes of O3 and PM. Global modeling indicates that as air pollution programs reduce SO2 to meet health and other air quality goals, near-term warming accelerates due to “unmasking” of warming induced by rising CO2. Air pollutant controls on CH4, a potent GHG and precursor to global O3 levels, and on sources with high black carbon (BC) to organic carbon (OC) ratios could offset near-term warming induced by SO2 emission reductions, while reducing global background O3 and regionally high levels of PM. Lowering peak warming requires decreasing atmospheric CO2, which for some source categories would also reduce co-emitted air pollutants or their precursors. Model projections for alternative climate and air quality scenarios indicate a wide range for U.S. surface O3 and fine PM, although regional projections may be confounded by interannual to decadal natural climate variability. Continued implementation of U.S. NOx emission controls guards against rising pollution levels triggered either by climate change or by global emission growth.

During the spring 2017 nesting season, we observed a severe localized hailstorm that afforded us an opportunity to measure the immediate demographic effects on a small breeding aggregation of Golden-winged Warblers (Vermivora chrysoptera). The hailstorm produced approximately 2.5 cm diameter hail and apparently caused the failure of 89{\%} (8/9) of monitored Golden-winged Warbler nests in a patch of early-successional forest in north-central Pennsylvania. Seven of the 8 failed nests contained broken eggs and all nests at the site showed signs of nest cup damage. Two dead Golden-winged Warbler females were found within 0.5 m of their nests. We suspect that additional mortalities of female and male Golden-winged Warblers occurred because several thorough searches of the early-successional patch revealed little territorial or renesting behavior in the following weeks. We noted hail-caused vegetation damage across the site characterized by varying levels of defoliation and destruction to herbaceous vegetation, Rubus, and even saplings and canopy trees. Storm events such as the one described here are well known to cause mortality in grassland species; however, events that result in forest-dependent passerine mortality are notably less common.

These records indicate that the first tropical cyclone in the South Indian Ocean to intensify to CAT5 status did so in 1994. This date is significantly later than the first CAT5 storms recorded in the IBTrACS database for the Atlantic Ocean (1924) and the North Pacific (1951) recorded from ship records, and half a decade later than those of the North Indian Ocean (1989) and South Pacific (1988), captured from satellite imagery.

This recent emergence of tropical cyclones attaining category five intensity in the South Indian Ocean is of significance for the forecasting of tropical cyclone landfall and the anticipation of storm damage for the developing economies that characterise the region.

Two calibration stages were explored, partial (P1), where experimental dry matter data were not provided, and full (P2). The median model ensemble response outperformed any single model in terms of replicating observed yield across all locations. Uncertainty in simulated yield decreased from 38{\%} to 20{\%} between P1 and P2. Model uncertainty increased with interannual variability, and predictions for all agronomic variables were significantly different from one model to another (P {\textless} 0.001). Uncertainty averaged 15{\%} higher for low- vs. high-input sites, with larger differences observed for evapotranspiration (ET), nitrogen uptake, and water use efficiency as compared to dry matter. A minimum of five partial, or three full, calibrated models was required for an ensemble approach to keep variability below that of common field variation. Model variation was not influenced by change in carbon dioxide (C), but increased as much as 41{\%} and 23{\%} for yield and ET, respectively, as temperature (T) or rainfall (W) moved away from historical levels.

Using the maximum entropy method (MaxEnt), we combined regional land-use projections and climatic data from the CMIP5 multimodel ensemble to investigate the monthly probability of fire occurrence in the mid (2041?2070) and late (2071?2100) 21st century in the Brazilian Amazon. We found striking spatial variation in the fire relative probability (FRP) change along the months, with October showing the highest overall change. Considering climate only, the area with FRP ≥ 0.3 (a threshold chosen based on the literature) in October increases 6.9{\%} by 2071?2100 compared to the baseline period under the representative concentration pathway (RCP) 4.5 and 27.7{\%} under the RCP 8.5. The best-case land-use scenario (?Sustainability?) alone causes a 10.6{\%} increase in the area with FRP ≥ 0.3, while the worse-case land-use scenario (?Fragmentation?) causes a 73.2{\%} increase. The optimistic climate-land-use projection (Sustainability and RCP 4.5) causes a 21.3{\%} increase in the area with FRP ≥ 0.3 in October by 2071?2100 compared to the baseline period. In contrast, the most pessimistic climate-land-use projection (Fragmentation and RCP 8.5) causes a widespread increase in FRP (113.5{\%} increase in the area with FRP ≥ 0.3), and prolongs the fire season, displacing its peak. Combining the Sustainability land-use and RCP 8.5 scenarios causes a 39.1{\%} increase in the area with FRP ≥ 0.3.

Results show that Europe will likely face a progressive increase in overall climate hazard with a prominent spatial gradient towards south-western regions mainly driven by the rise of heat waves, droughts and wildfires. Key hotspots emerge particularly along coastlines and in floodplains, often highly populated and economically pivotal, where floods and windstorms could be critical in combination with other climate hazards.

Yet, future risks of weather-related hazards on human lives in view of climate and demographic changes have not been comprehensively investigated. METHODS We assessed the risk of weather-related hazards to the European population in terms of annual numbers of deaths in 30 year intervals relative to the reference period (1981-2010) up to the year 2100 (2011-40, 2041-70, and 2071-100) by combining disaster records with high-resolution hazard and demographic projections in a prognostic modelling framework. We focused on the hazards with the greatest impacts-heatwaves and cold waves, wildfires, droughts, river and coastal floods, and windstorms-and evaluated their spatial and temporal variations in intensity and frequency under a business-as-usual scenario of greenhouse gas emissions. We modelled long-term demographic dynamics through a territorial modelling platform to represent the evolution of human exposure under a corresponding middle-of-the-road socioeconomic scenario. We appraised human vulnerability to weather extremes on the basis of more than 2300 records collected from disaster databases during the reference period and assumed it to be static under a scenario of no adaptation. FINDINGS We found that weather-related disasters could affect about two-thirds of the European population annually by the year 2100 (351 million people exposed per year [uncertainty range 126 million to 523 million] during the period 2071-100) compared with 5{\%} during the reference period (1981-2010; 25 million people exposed per year). About 50 times the number of fatalities occurring annually during the reference period (3000 deaths) could occur by the year 2100 (152 000 deaths [80 500-239 800]). Future effects show a prominent latitudinal gradient, increasing towards southern Europe, where the premature mortality rate due to weather extremes (about 700 annual fatalities per million inhabitants [482-957] during the period 2071-100 vs 11 during the reference period) could become the greatest environmental risk factor. The projected changes are dominated by global warming (accounting for more than 90{\%} of the rise in risk to human beings), mainly through a rise in the frequency of heatwaves (about 2700 heat-related fatalities per year during the reference period vs 151 500 [80 100-239 000] during the period 2071-100). INTERPRETATION Global warming could result in rapidly rising costs of weather-related hazards to human beings in Europe unless adequate adaptation measures are taken. Our results could aid in prioritisation of regional investments to address the unequal burden of effects on human beings of weather-related hazards and differences in adaptation capacities.

In order to plan suitable adaptation strategies it is important for decision makers to know how drought conditions will develop at regional scales. This paper therefore addresses the issue of future developments in streamflow drought characteristics across Europe. Through offline coupling of a hydrological model with an ensemble of bias-corrected climate simulations (IPCC SRES A1B) and a water use scenario (Economy First), long-term (1961-2100) ensemble streamflow simulations are generated that account for changes in climate, and the uncertainty therein, and in water consumption. Using extreme value analysis we derive minimum flow and deficit indices and evaluate how the magnitude and severity of low-flow conditions may evolve throughout the 21st century. This analysis shows that streamflow droughts will become more severe and persistent in many parts of Europe due to climate change, except for northern and northeastern parts of Europe.

Here we show how single- and multi-hazard damage to energy, transport, industrial, and social critical infrastructures in Europe are likely to develop until the year 2100 under the influence of climate change. We combine a set of high-resolution climate hazard projections, a detailed representation of physical assets in various sectors and their sensitivity to the hazards, and more than 1100 records of losses from climate extremes in a prognostic modelling framework. We find that damages could triple by the 2020s, multiply six-fold by mid-century, and amount to more than 10 times present damage of €3.4 billion per year by the end of the century due only to climate change. Damage from heatwaves, droughts in southern Europe, and coastal floods shows the most dramatic rise, but the risks of inland flooding, windstorms, and forest fires will also increase in Europe, with varying degrees of change across regions. Economic losses are highest for the industry, transport, and energy sectors. Future losses will not be incurred equally across Europe. Southern and south-eastern European countries will be most affected and, as a result, will probably require higher costs of adaptation.

Yet our knowledge about past occurrences15 and the future progression of MHWs is very limited. Here we use satellite observations and a suite of Earth system model simulations to show that MHWs have already become longer-lasting and more frequent, extensive and intense in the past few decades, and that this trend will accelerate under further global warming. Between 1982 and 2016, we detect a doubling in the number of MHW days, and this number is projected to further increase on average by a factor of 16 for global warming of 1.5 degrees Celsius relative to preindustrial levels and by a factor of 23 for global warming of 2.0 degrees Celsius. However, current national policies for the reduction of global carbon emissions are predicted to result in global warming of about 3.5 degrees Celsius by the end of the twenty-first century16, for which models project an average increase in the probability of MHWs by a factor of 41. At this level of warming, MHWs have an average spatial extent that is 21 times bigger than in preindustrial times, last on average 112 days and reach maximum sea surface temperature anomaly intensities of 2.5 degrees Celsius. The largest changes are projected to occur in the western tropical Pacific and Arctic oceans. Today, 87 per cent of MHWs are attributable to human-induced warming, with this ratio increasing to nearly 100 per cent under any global warming scenario exceeding 2 degrees Celsius.

Previous assessments found that the summed contributions of ice-mass loss, terrestrial water storage and thermal expansion of the ocean could not be reconciled with observed changes in global-mean sea level, implying that changes in sea level or some contributions to those changes were poorly constrained2,3. Recent improvements to observational data, our understanding of the main contributing processes to sea-level change and methods for estimating the individual contributions, mean another attempt at reconciliation is warranted. Here we present a probabilistic framework to reconstruct sea level since 1900 using independent observations and their inherent uncertainties. The sum of the contributions to sea-level change from thermal expansion of the ocean, ice-mass loss and changes in terrestrial water storage is consistent with the trends and multidecadal variability in observed sea level on both global and basin scales, which we reconstruct from tide-gauge records. Ice-mass loss—predominantly from glaciers—has caused twice as much sea-level rise since 1900 as has thermal expansion. Mass loss from glaciers and the Greenland Ice Sheet explains the high rates of global sea-level rise during the 1940s, while a sharp increase in water impoundment by artificial reservoirs is the main cause of the lower-than-average rates during the 1970s. The acceleration in sea-level rise since the 1970s is caused by the combination of thermal expansion of the ocean and increased ice-mass loss from Greenland.

With regard to floods, an interesting spatial patter can be observed. On the one hand, the number of floods in the Asian part of the country has increased, whereas on the other hand, the number and intensity of floods in estuarine areas in the European part of Russia have significantly reduced since the middle of the twentieth century, especially in the 2000s. This decrease can be attributed to runoff flooding in the mouths of regulated rivers, with an effective system of flood and ice jam protection. The analysis shows that there is an 8–12-year periodicity in the number of flood occurrences and that flood surges have intensified over the last 110 years, especially on the European territory of Russia. An integrated index that accounts for flood hazards and socio-economic vulnerability was calculated for each region of Russia.

We show observationally that the dry-season length over southern Amazonia has increased significantly since 1979. We do not know what has caused this change, although it resembles the effects of anthropogenic climate change. The global climate models that were presented in the Intergovernmental Panel on Climate Change's fifth assessment report seem to substantially underestimate the variability of the dry-season length. Such a bias implies that the future change of the dry-season length, and hence the risk of rainforest die-back, may be underestimated by the projections of these models.We have observed that the dry-season length (DSL) has increased over southern Amazonia since 1979, primarily owing to a delay of its ending dates (dry-season end, DSE), and is accompanied by a prolonged fire season. A poleward shift of the subtropical jet over South America and an increase of local convective inhibition energy in austral winter (June–August) seem to cause the delay of the DSE in austral spring (September–November). These changes cannot be simply linked to the variability of the tropical Pacific and Atlantic Oceans. Although they show some resemblance to the effects of anthropogenic forcings reported in the literature, we cannot attribute them to this cause because of inadequate representation of these processes in the global climate models that were presented in the Intergovernmental Panel on Climate Change's Fifth Assessment Report. These models significantly underestimate the variability of the DSE and DSL and their controlling processes. Such biases imply that the future change of the DSE and DSL may be underestimated by the climate projections provided by the Intergovernmental Panel on Climate Change's Fifth Assessment Report models. Although it is not clear whether the observed increase of the DSL will continue in the future, were it to continue at half the rate of that observed, the long DSL and fire season that contributed to the 2005 drought would become the new norm by the late 21st century.

However, while many studies explored the projected occurrence of hot extremes on terrestrial systems, few studies dealt with marine systems, so that both the expected change in marine heat waves occurrence and the effects on marine organisms and ecosystems remain less understood and surprisingly poorly quantified. Here we: (i) assess how much more frequent, severe, and depth-penetrating marine heat waves will be in the Mediterranean area in the next decades by post-processing the output of an ocean general circulation model; and (ii) show that heat waves increase will impact on many species that live in shallow waters and have reduced motility, and related economic activities. This information is made available also as a dataset of temperature threshold exceedance indexes that can be used in combination with biological information to produce risk assessment maps for target species or biomes across the whole Mediterranean Sea. As case studies we compared projected heat waves occurrence with thermotolerance thresholds of low motility organisms.

Experiments were conducted using three regional climate models with horizontal resolutions of approximately 12 km (HadGEM3-RA) and 25 km (HadRM3P and RegCM4). The simulations are driven by boundary data from a subset of global climate model simulations from the CMIP5 ensemble. Here we present the experimental design, the methodology for selecting CMIP5 models, the results of the model validation, and future projections of changes to tropical cyclone frequency and intensity by the mid-21st century. The models used are shown to represent the key climatological features of tropical cyclones across the domain, including the seasonality and general distribution of intensities, but issues remain in resolving very intense tropical cyclones and simulating realistic trajecto-ries across their life-cycles. Acknowledging model inadequacies and uncertainties associated with future climate model projections, the results show a range of plausible changes with a tendency for fewer but slightly more intense tropical cyclones. These results are consistent with the basin-wide results reported in the IPCC AR5 and provide clear evidence that the findings from these previous studies are applicable in the Philippines region.

While previous investigators have examined the association between temperature extremes and large-scale atmospheric circulation variability, the role of land–atmosphere coupling on temperature extremes over the monsoon-dominated region of India is not well understood. This study presents an analysis of hydro-meteorological datasets for the 67-year period (1948–2014) to assess the impact of long-term soil moisture changes on temperature extremes over the Indian region. Firstly, our findings show that the hot-spot of land–atmosphere coupling located across north-central India (NCI) is a region where SM variations can significantly influence temperature extremes. We further note that the NCI region experienced a significant declining trend in SM (about 1.1 mm/decade) during 1948–2014, in association with the decreasing trend of monsoon precipitation. Our findings suggest that the long-term decrease of SM over the NCI has favored increased incidence of temperature extremes through strengthening (weakening) of sensible (latent) heat fluxes; while the loss of soil moisture memory has additionally promoted increased variability of temperature extremes. The frequency, duration and variability of extreme temperatures are found to increase significantly by 1–2 occurrences, 5–6 days and 43{\%}, respectively, in association with a decrease of 10 mm SM over NCI. The Generalized Extreme Value (GEV) distributions are fitted to extreme temperature duration (ExTD) using SM as a covariate to quantify the role of SM on temperature extremes over NCI. GEV analysis reveals that drier SM conditions (10th percentile) lead to an increase in the 67-year return value of ExTD by 9–10 days, relative to wet SM conditions (90th percentile) over NCI. Furthermore, it is interesting to note that the rise in temperature extremes over NCI in the recent three decades has been more prominent during the monsoon and post-monsoon seasons as compared to the pre-monsoon months.}, author = {Ganeshi, Naresh G and Mujumdar, Milind and Krishnan, R and Goswami, Mangesh}, doi = {10.1016/j.jhydrol.2020.125183}, issn = {00221694}, journal = {Journal of Hydrology}, keywords = {Generalized extreme value distribution,North-central India,Soil moisture memory,Soil moisture-temperature coupling,Surface energy partitioning,Temperature extremes}, month = {oct}, pages = {125183}, title = {{Understanding the linkage between soil moisture variability and temperature extremes over the Indian region}}, url = {https://www.sciencedirect.com/science/article/pii/S0022169420306430 https://linkinghub.elsevier.com/retrieve/pii/S0022169420306430}, volume = {589}, year = {2020} } @article{Ganguli2019, abstract = {Abstract We analyze trends in compound flooding resulting from high coastal water levels (HCWLs) and peak river discharge over northwestern Europe during 1901?2014.

The evaluation of occupational heat stress requires measurement of four thermal climate factors (air temperature, humidity, air velocity and heat radiation); available weather station data may serve this purpose. However, the use of meteorological data for occupational heat stress assessment is limited because weather stations do not traditionally and directly measure some important climate factors, e.g. solar radiation. In addition, local workplace environmental conditions such as local heat sources, metabolic heat production within the human body, and clothing properties, all affect the exchange of heat between the body and the environment. A robust occupational heat stress index should properly address all these factors. This article reviews and highlights a number of selected heat stress indices, indicating their advantages and disadvantages in relation to meteorological data, local workplace environments, body heat production and the use of protective clothing.

Climate and landslides act at only partially overlapping spatial and temporal scales, complicating the evaluation of the climate impacts on landslides. We review the literature on landslide-climate studies, and find a bias in their geographical distribution, with large parts of the world not investigated.

We examine advantages and limits of the approaches adopted to evaluate the effects of climate variations on landslides, including prospective modelling and retrospective methods that use landslide and climate records. We consider changes in temperature, precipitation, wind and weather systems, and their direct and indirect effects on the stability of single slopes, and we use a probabilistic landslide hazard model to appraise regional landslide changes. Our review indicates that the modelling results of landslide-climate studies depend more on the emission scenarios, the Global Circulation Models, and the methods to downscale the climate variables, than on the description of the variables controlling slope processes. We advocate for constructing ensembles of projections based on a range of emissions scenarios, and to use carefully results from worst-case scenarios that may over/under-estimate landslide hazards and risk. We further advocate that uncertainties in the landslide projections must be quantified and communicated to decision makers and the public. We perform a preliminary global assessment of the future landslide impact, and we present a global map of the projected impact of climate change on landslide activity and abundance.

Since 2010 an uninterrupted sequence of dry years, with annual rainfall deficits ranging from 25 to 45 {\%}, has prevailed in central Chile (western South America, 30–38° S). Although intense 1- or 2-year droughts are recurrent in this Mediterranean-like region, the ongoing event stands out because of its longevity and large extent. The extraordinary character of the so-called central Chile megadrought (MD) was established against century long historical records and a millennial tree-ring reconstruction of regional precipitation. The largest MD-averaged rainfall relative anomalies occurred in the northern, semi-arid sector of central Chile, but the event was unprecedented to the south of 35° S. ENSO-neutral conditions have prevailed since 2011 (except for the strong El Ni{\~{n}}o in 2015), contrasting with La Ni{\~{n}}a conditions that often accompanied past droughts. The precipitation deficit diminished the Andean snowpack and resulted in amplified declines (up to 90 {\%}) of river flow, reservoir volumes and groundwater levels along central Chile and westernmost Argentina. In some semi-arid basins we found a decrease in the runoff-to-rainfall coefficient. A substantial decrease in vegetation productivity occurred in the shrubland-dominated, northern sector, but a mix of greening and browning patches occurred farther south, where irrigated croplands and exotic forest plantations dominate. The ongoing warming in central Chile, making the MD one of the warmest 6-year periods on record, may have also contributed to such complex vegetation changes by increasing potential evapotranspiration. We also report some of the measures taken by the central government to relieve the MD effects and the public perception of this event.

The numerical simulations were used for computing the Canadian Fire Weather Index, for deriving the climatology of fire weather in the study area and investigating the presence of long-term trends, with particular emphasis on extremes during the May to September period. Results suggest that the Euro-Mediterranean fire weather follows a zonal pattern, characterized by adverse conditions occurring most frequently in the southern parts. Air temperature and relative humidity are the key drivers of fire weather in the study area, with precipitation and wind exerting less influence. Based on the conducted spatial trend analysis, extreme fire weather conditions have become more prevalent in the Iberian Peninsula and eastern Balkans, whereas declining trends occur in the Southeast Mediterranean basin. For both cases, the trends in fire weather extremes appear to coincide with trends in the input meteorological variables.

However, intracellular mechanisms leading to VPS34 activation remain unclear. Here, we report that Src directly phosphorylates VPS34, and that this phosphorylation activates VPS34 lipid kinase activity, leading to Src-Y527F-mediated cellular transformation. Silencing endogenous VPS34 specifically inhibits Src-Y527F-induced colony formation in soft agar, but not Ras-G12V-induced colony formation. We have identified two novel hVPS34 mutations, which either eliminate lipid kinase activity (kinase-dead mutant) or reduce tyrosine phosphorylation by Src-Y527F. When kinase-dead mutant of hVPS34 is stably expressed in Src-Y527F-transformed cells, transformation activities are blocked, indicating that the lipid kinase activity of hVPS34 is essential for Src-mediated cellular transformation. Furthermore, stable expression of this hVPS34 kinase-dead mutant causes an increased number of binucleate and multinucleate cells, suggesting that the kinase activity of hVPS34 is also required for cytokinesis. Moreover, when the hVPS34 mutant that has reduced tyrosine phosphorylation by Src is stably expressed in Src-Y527F-transformed cells, Src-Y527F-stimulated colony formation is also reduced. Data presented here provide important evidence that VPS34 lipid kinase activity could be positively regulated by Src-mediated tyrosine phosphorylation in mammalian cells. This finding highlights a previously unappreciated relationship between VPS34, a class III phosphatidylinositol-3-kinase, and Src non-receptor tyrosine kinase. Additionally, we find that the levels of VPS34 expression and tyrosine phosphorylation are correlated with the tumorigenic activity of human breast cancer cells, indicating that Src to VPS34 signaling warrants further investigation as a pathway contributing to the development and progression of human cancers.}, address = {Reston, VA, USA}, author = {Gibbs, Ann E. and Richmond, Bruce M.}, doi = {10.3133/ofr20151048.}, pages = {96}, publisher = {U.S. Geological Survey (USGS)}, series = {USGS Open-File Report 2015-1048}, title = {{National Assessment of Shoreline Change – Historical Shoreline Change Along the North Coast of Alaska, U.S.-Canadian Border to Icy Cape}}, url = {http://pubs.usgs.gov/of/2015/1048/pdf/ofr2015-1048.pdf}, year = {2015} } @article{Gidhagen2020, abstract = {The growing share of Europe's population living in cities makes urban climate change impact assessment and adaptation a critical issue.

Such objectives, however, are difficult to achieve for several reasons. Uncertainties about future fire activity can be superimposed on the short time period covered by existing meteorological data and fire statistics, from which a historical range of variability can be determined. Regional fire activity is also tremendously variable over time, such that contemporary fire records cannot provide information on the full range of fire activity variability a given forest experienced and adapted to. This factor is increasingly important when it comes to determining the resilience of boreal forests to changes in climate and disturbance regimes. In this paper, we present a synthesis of past, present and future trends in seasonal fire danger and fire activity based on data gathered in eastern Canadian boreal forests over the last 20. years, and we provide a critical assessment of the ability to conduct sustainable forest management over the 21st century. The data synthesis provides compelling evidence of a synchronous pattern of decreasing fire-conducive climatic conditions and activity of large fire seasons over the last 2000. years in the eastern coniferous boreal forest. Model simulations suggest that the climate will become drier in upcoming decades, driving future fire activity close to the upper bound of the pre-industrial range of variability. The effects of increasing fire incidence cumulated with forest harvesting may thus pose a risk to forest resilience in the future. This ecological knowledge should help us to define forest management strategies and practices considering future fire activity changes forecasted under climate change. Development of alternative silvicultural interventions that would emulate secondary disturbances (e.g. wind, insects) rather than fire would be necessary to maintain pre-industrial forest characteristics (e.g. composition and age class distribution), and associated forest resilience. {\textcopyright} 2012.}, author = {Girardin, Martin P. and Ali, Adam A. and Carcaillet, Christopher and Gauthier, Sylvie and H{\'{e}}ly, Christelle and {Le Goff}, H{\'{e}}lo{\"{i}}se and Terrier, Aur{\'{e}}lie and Bergeron, Yves}, doi = {10.1016/j.foreco.2012.07.005}, issn = {03781127}, journal = {Forest Ecology and Management}, keywords = {Climatic change,Forest fires,Holocene,Paleoecology,Sedimentary charcoal,Tree rings}, month = {apr}, pages = {238--249}, publisher = {Elsevier}, title = {{Fire in managed forests of eastern Canada: Risks and options}}, volume = {294}, year = {2013} } @article{Girardin2009, abstract = {The Fire Weather Index System has been in use across Canada for the past 30 years in the daily operations of fire management agencies.

Projections of changes in the hydrological cycle from global hydrological models (GHMs) driven by global climate models (GCMs) are critical for understanding future occurrence of hydrological extremes. However, uncertainties remain large and need to be better assessed. In particular, recent studies have pointed to a considerable contribution of GHMs that can equal or outweigh the contribution of GCMs to uncertainty in hydrological projections. Using six GHMs and five GCMs from the ISI-MIP multi-model ensemble, this study aims: (i) to assess future changes in the frequency of both high and low flows at the global scale using control and future (RCP8.5) simulations by the 2080s, and (ii) to quantify, for both ends of the runoff spectrum, GCMs and GHMs contributions to uncertainty using a two-way ANOVA. Increases are found in high flows for northern latitudes and in low flows for several hotspots. Globally, the largest source of uncertainty is associated with GCMs, but GHMs are the greatest source in snow-dominated regions. More specifically, results vary depending on the runoff metric, the temporal (annual and seasonal) and regional scale of analysis. For instance, uncertainty contribution from GHMs is higher for low flows than it is for high flows, partly owing to the different processes driving the onset of the two phenomena (e.g. the more direct effect of the GCMs' precipitation variability on high flows). This study provides a comprehensive synthesis of where future hydrological extremes are projected to increase and where the ensemble spread is owed to either GCMs or GHMs. Finally, our results underline the need for improvements in modelling snowmelt and runoff processes to project future hydrological extremes and the importance of using multiple GCMs and GHMs to encompass the uncertainty range provided by these two sources.}, author = {Giuntoli, I. and Vidal, J.-P. and Prudhomme, C. and Hannah, D.M.}, doi = {10.5194/esd-6-267-2015}, journal = {Earth System Dynamics}, number = {1}, pages = {267--285}, title = {{Future hydrological extremes: The uncertainty from multiple global climate and global hydrological models}}, volume = {6}, year = {2015} } @article{Gizaw2017, abstract = {Various drought prone regions of sub-Saharan Africa (SSAF) have been affected by severe droughts in recent decades and centuries, which had caused catastrophic humanitarian crisis.

Presently, however, the concurrent effects of low oxygen and acidification on marine organisms are largely unknown, as most prior studies of marine hypoxia have not considered pH levels. We experimentally assessed the consequences of hypoxic and acidified water for early life stage bivalves (bay scallops, Argopecten irradians, and hard clams, Mercenaria mercenaria), marine organisms of significant economic and ecological value and sensitive to climate change. In larval scallops, experimental and naturally-occurring acidification (pH, total scale = 7.4-7.6) reduced survivorship (by {\textgreater}50{\%}), low oxygen (30-50 µM) inhibited growth and metamorphosis (by {\textgreater}50{\%}), and the two stressors combined produced additively negative outcomes. In early life stage clams, however, hypoxic waters led to 30{\%} higher mortality, while acidified waters significantly reduced growth (by 60{\%}). Later stage clams were resistant to hypoxia or acidification separately but experienced significantly (40{\%}) reduced growth rates when exposed to both conditions simultaneously. Collectively, these findings demonstrate that the consequences of low oxygen and acidification for early life stage bivalves, and likely other marine organisms, are more severe than would be predicted by either individual stressor and thus must be considered together when assessing how ocean animals respond to these conditions both today and under future climate change scenarios.}, author = {Gobler, Christopher J. and DePasquale, Elizabeth L. and Griffith, Andrew W. and Baumann, Hannes}, doi = {10.1371/journal.pone.0083648}, editor = {Dupont, Sam}, isbn = {1932-6203}, issn = {1932-6203}, journal = {PLOS ONE}, month = {jan}, number = {1}, pages = {e83648}, pmid = {24416169}, title = {{Hypoxia and Acidification Have Additive and Synergistic Negative Effects on the Growth, Survival, and Metamorphosis of Early Life Stage Bivalves}}, url = {https://dx.plos.org/10.1371/journal.pone.0083648}, volume = {9}, year = {2014} } @article{Gobler2016, abstract = {There is increasing recognition that low dissolved oxygen (DO) and low pH conditions co-occur in many coastal and open ocean environments. Within temperate ecosystems, these conditions not only develop seasonally as temperatures rise and metabolic rates accelerate, but can also display strong diurnal variability, especially in shallow systems where photosynthetic rates ameliorate hypoxia and acidification by day. Despite the widespread, global co-occurrence of low pH and low DO and the likelihood that these conditions may negatively impact marine life, very few studies have actually assessed the extent to which the combination of both stressors elicits additive, synergistic or antagonistic effects in marine organisms. We review the evidence from published factorial experiments that used static and/or fluctuating pH and DO levels to examine different traits (e.g. survival, growth, metabolism), life stages and species across a broad taxonomic spectrum. Additive negative effects of combined low pH and low DO appear to be most common; however, synergistic negative effects have also been observed. Neither the occurrence nor the strength of these synergistic impacts is currently predictable, and therefore, the true threat of concurrent acidification and hypoxia to marine food webs and fisheries is still not fully understood. Addressing this knowledge gap will require an expansion of multi-stressor approaches in experimental and field studies, and the development of a predictive framework. In consideration of marine policy, we note that DO criteria in coastal waters have been developed without consideration of concurrent pH levels. Given the persistence of concurrent low pH–low DO conditions in estuaries and the increased mortality experienced by fish and bivalves under concurrent acidification and hypoxia compared with hypoxia alone, we conclude that such DO criteria may leave coastal fisheries more vulnerable to population reductions than previously anticipated.}, author = {Gobler, Christopher J. and Baumann, Hannes}, doi = {10.1098/rsbl.2015.0976}, isbn = {1744-9561}, issn = {1744-9561}, journal = {Biology Letters}, keywords = {Eutrophication,Fisheries,Hypoxia,Ocean acidification}, month = {may}, number = {5}, pages = {20150976}, pmid = {27146441}, title = {{Hypoxia and acidification in ocean ecosystems: coupled dynamics and effects on marine life}}, url = {https://royalsocietypublishing.org/doi/10.1098/rsbl.2015.0976}, volume = {12}, year = {2016} } @article{Gobler2017a, abstract = {This study used high-resolution (daily, quarter-degree resolution) sea-surface temperature records to model trends in growth rates and bloom-season duration for two of the most toxic and widespread harmful algal bloom species indigenous to the North Atlantic and North Pacific oceans.

Here, the change in occurrence of clustered storms and its association with atmospheric oscillation modes were investigated in New Zealand waters using 44 years (1958–2001) of wave hindcast data. First, long-term averages of cluster parameters (number of storms within the cluster, potential for coastal erosion, and cluster duration) were assessed. Then, the relationships between clustering and the El Ni{\~{n}}o-Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), Zonal Wavenumber-3 Pattern (ZW3), Pacific Decadal Oscillation (PDO), and Southern Annular Mode (SAM) were explored through correlation analysis over several timescales. Clusters were more frequently observed to the northeast of New Zealand and on the central eastern coast of the South Island. The most vulnerable regions to cluster-induced coastal erosion were southern New Zealand and the northwestern coast, which resulted from steady southwesterly swells, although clusters with the longest duration occurred on the east coast of the South Island. Trends suggest that clusters have incorporated more storms, have become more hazardous, and have increased in duration, particularly along the South Island coastline. Although these trends may be sensitive to the reanalysed wind fields used to force the wave hindcast, they reflect trends in the ENSO, PDO, and SAM. Stronger southwesterly winds during El Ni{\~{n}}o (negative ENSO) and El Ni{\~{n}}o-like conditions (positive IOD/PDO) generated more clustered storms mainly on the southwestern coast of New Zealand, whereas increases in clustering were observed on the north coast during La Ni{\~{n}}a and La Ni{\~{n}}a-like conditions (stronger northeasterly winds). Higher occurrence of clustering was also evident on the west coast during the strong atmospheric zonal flow associated with negative ZW3.

METHODS We built parent models of eight daily counts of admission records using weather station observations, census population estimates and public holiday data. We added heat stress indices; models with lower Akaike Information Criterion scores were judged a better fit. RESULTS Five of the eight parent models demonstrated adequate fit. Daily maximum Simplified Wet Bulb Globe Temperature (sWBGT) consistently improved fit more than most other indices; temperature and heatwave indices also modelled some health outcomes well. Humidity and heat-humidity indices better fit counts of patients who died following admission. CONCLUSIONS Maximum sWBGT is an ideal measure of heat stress for these types of Sydney hospital admissions. Simple temperature indices are a good fallback where a narrower range of conditions is investigated. Implications for public health: This study confirms the importance of selecting appropriate heat stress indices for modelling.

Drought conditions have been associated with the increase of large wildfires, area burned and longer fire seasons. This study examines the influence of drought on fire regimes and discusses landscape management opportunities to decrease fire hazard. Specifically, we investigate the effect of the 2010–2015 Megadrought (MD) compared to 1990–2009 period on fire activity (fire-season length, number of fires and burned area across months, fire sizes, regions and vegetation cover types, simultaneity, and duration of fires) in central and south-central Chile (32°–39° S), using contemporary fire statistics derived from the Chilean Forest Service. For large fire events ({\textgreater}200 ha) the average season length increased by 67 d (44{\%}), comparing 2010–2015 to 1990–2009. Earlier and later ignition dates resulted in extended fire seasons in MD years. During the MD, the number, area burned, simultaneity, and duration of large fires increased significantly compared to the control period, including the unprecedented occurrence of large fires during winter. The burned area in large fires increased in all vegetation types, during the MD compared to the control period, especially in the exotic plantation cover type. The regions that were most affected by fire (i.e., total area burned) during the MD were Maule, B{\'{i}}o-B{\'{i}}o, and Araucan{\'{i}}a (35–39° S) that concentrate {\textgreater}75{\%} of forest plantations in Chile. Although both maximum temperatures and precipitation are drivers of fire activity, a simple attribution analysis indicates that the sustained rainfall deficit during 2010–2015 was the most critical factor in the enhanced fire activity. Future climate change predictions indicate more recurrent, intense, and temporally extended droughts for central and south-central Chile. Under this scenario, land-use planning and fire and forest management strategies must promote a more diverse and less flammable landscape mosaic limiting high load, homogenous, and continuous exotic plantations.}, author = {Gonz{\'{a}}lez, Mauro E. and G{\'{o}}mez-Gonz{\'{a}}lez, Susana and Lara, Antonio and Garreaud, Ren{\'{e}} and D{\'{i}}az-Hormaz{\'{a}}bal, Ignacio}, doi = {10.1002/ecs2.2300}, issn = {21508925}, journal = {Ecosphere}, keywords = {drought,fire regimes,fire-prone vegetation,fire-season length}, month = {aug}, number = {8}, pages = {e02300}, title = {{The 2010–2015 Megadrought and its influence on the fire regime in central and south-central Chile}}, url = {http://doi.wiley.com/10.1002/ecs2.2300}, volume = {9}, year = {2018} } @article{Gonzalez-Aleman2019, author = {Gonz{\'{a}}lez‐Alem{\'{a}}n, Juan J. and Pascale, Salvatore and Gutierrez‐Fernandez, Jes{\'{u}}s and Murakami, Hiroyuki and Gaertner, Miguel A. and Vecchi, Gabriel A.}, doi = {10.1029/2018GL081253}, issn = {0094-8276}, journal = {Geophysical Research Letters}, keywords = {Medicanes,climate change,convection,cutoff lows,global climate models,tropical cyclones}, month = {feb}, number = {3}, pages = {1754--1764}, publisher = {John Wiley {\&} Sons, Ltd}, title = {{Potential Increase in Hazard From Mediterranean Hurricane Activity With Global Warming}}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1029/2018GL081253 http://doi.wiley.com/10.1029/2018GL081253}, volume = {46}, year = {2019} } @article{Gonzalez2018b, author = {Gonzalez, Patrick and Wang, Fuyao and Notaro, Michael and Vimont, Daniel J and Williams, John W}, doi = {10.1088/1748-9326/aade09}, issn = {1748-9326}, journal = {Environmental Research Letters}, month = {sep}, number = {10}, pages = {104001}, publisher = {IOP Publishing}, title = {{Disproportionate magnitude of climate change in United States national parks}}, url = {http://stacks.iop.org/1748-9326/13/i=10/a=104001?key=crossref.4517a7dddf1a278ac256e838edfa5f0f}, volume = {13}, year = {2018} } @article{GOODESS2019100139, abstract = {The development of successful climate services faces a number of challenges, including the identification of the target audience and their needs and requirements, and the effective communication of complex climate information, through engagement with a range of stakeholders.

The modelled wind variability and wind distribution compare favourably to observations from three automatic weather stations in the ablation zone of southwest Greenland. The Weibull shape parameter is used to classify the wind climate. High values ($\kappa$ {\textgreater} 4) are found in northern Greenland, indicative of uniform winds and a dominant katabatic forcing, while lower values ($\kappa$ {\textless} 3) are found over the ocean and southern Greenland, where the synoptic forcing dominates. Very high values of the shape parameter are found over concave topography where confluence strengthens the katabatic circulation, while very low values are found in a narrow band along the coast due to barrier winds. To simulate the future (2081-2098) wind climate RACMO2 was forced with the HadGEM2-ES general circulation model using a scenario of mid-range radiative forcing of +4.5 W m-2 by 2100. For the future simulated climate, the near-surface potential temperature deficit reduces in all seasons in regions where the surface temperature is below the freezing point, indicating a reduction in strength of the near-surface temperature inversion layer. This leads to a wind speed reduction over the central ice sheet where katabatic forcing dominates, and a wind speed increase over steep coastal topography due to counteracting effects of thermal and katabatic forcing. Thermally forced winds over the seasonally sea ice covered region of the Greenland Sea are reduced by up to 2.5 m s-1. {\textcopyright} 2013 Springer-Verlag Berlin Heidelberg.}, author = {Gorter, W. and van Angelen, J.

This is also true for agricultural regions, where exposure to extreme heat, particularly during key growth phases such as the reproductive period, can severely damage crop production in ways that are not captured by most crop models. Here, we analyze exposure of crops to physiologically critical temperatures in the reproductive stage (Tcrit), across the global harvested areas of maize, rice, soybean and wheat. Trends for the 1980–2011 period show a relatively weak correspondence (r = 0.19) between mean growing season temperature and Tcrit exposure trends, emphasizing the importance of separate analyses for Tcrit. Increasing Tcrit exposure in the past few decades is apparent for wheat in Central and South Asia and South America, and for maize in many diverse locations across the globe. Maize had the highest percentage (15{\%}) of global harvested area exposed to at least five reproductive days over Tcrit in the 2000s, although this value is somewhat sensitive to the exact temperature used for the threshold. While there was relatively little sustained exposure to reproductive days over Tcrit for the other crops in the past few decades, all show increases with future warming. Using projections from climate models we estimate that by the 2030s, 31, 16, and 11{\%} respectively of maize, rice, and wheat global harvested area will be exposed to at least five reproductive days over Tcrit in a typical year, with soybean much less affected. Both maize and rice exhibit non-linear increases with time, with total area exposed for rice projected to grow from 8{\%} in the 2000s to 27{\%} by the 2050s, and maize from 15 to 44{\%} over the same period. While faster development should lead to earlier flowering, which would reduce reproductive extreme heat exposure for wheat on a global basis, this would have little impact for the other crops. Therefore, regardless of the impact of other global change factors (such as increasing atmospheric CO2), reproductive extreme heat exposure will pose risks for global crop production without adaptive measures such as changes in sowing dates, crop and variety switching, expansion of irrigation, and agricultural expansion into cooler areas.}, author = {Gourdji, Sharon M and Sibley, Adam M and Lobell, David B}, doi = {10.1088/1748-9326/8/2/024041}, issn = {1748-9326}, journal = {Environmental Research Letters}, month = {jun}, number = {2}, pages = {024041}, publisher = {IOP Publishing}, title = {{Global crop exposure to critical high temperatures in the reproductive period: historical trends and future projections}}, url = {http://stacks.iop.org/1748-9326/8/i=2/a=024041?key=crossref.71d4bd7d0045166be569277634403f63}, volume = {8}, year = {2013} } @incollection{Gowda2018, address = {Washington, DC, USA}, author = {Gowda, Prasanna H. and Steiner, Jean and Olson, Carolyn and Boggess, Mark and Farrigan, Tracey and Grusak, Michael A.}, booktitle = {Impacts, Risks, and Adaptation in the United States: Fourth National Climate Assessment, Volume II}, doi = {10.7930/NCA4.2018.CH10}, editor = {Reidmiller, D.R. and Avery, C.W. and Easterling, D.R. and Kunkel, K.E. and Lewis, K.L.M. and Maycock, T.K. and Stewart, B.C.}, organization = {U.S. Global Change Research Program}, pages = {391--437}, title = {{Agriculture and Rural Communities}}, url = {https://nca2018.globalchange.gov/chapter/10/}, year = {2018} } @article{GraffZivin2014, author = {{Graff Zivin}, Joshua and Neidell, Matthew}, doi = {10.1086/671766}, issn = {0734-306X}, journal = {Journal of Labor Economics}, month = {jan}, number = {1}, pages = {1--26}, title = {{Temperature and the Allocation of Time: Implications for Climate Change}}, url = {https://www.journals.uchicago.edu/doi/10.1086/671766}, volume = {32}, year = {2014} } @article{Graham2015a, abstract = {Climate-induced coral bleaching is among the greatest current threats to coral reefs, causing widespread loss of live coral cover1.

Here we document and predict long-term reef responses to a major climate-induced coral bleaching event that caused unprecedented region-wide mortality of Indo-Pacific corals. Following loss of {\textgreater}90{\%} live coral cover, 12 of 21 reefs recovered towards pre-disturbance live coral states, while nine reefs underwent regime shifts to fleshy macroalgae. Functional diversity of associated reef fish communities shifted substantially following bleaching, returning towards pre-disturbance structure on recovering reefs, while becoming progressively altered on regime shifting reefs. We identified threshold values for a range of factors that accurately predicted ecosystem response to the bleaching event. Recovery was favoured when reefs were structurally complex and in deeper water, when density of juvenile corals and herbivorous fishes was relatively high and when nutrient loads were low. Whether reefs were inside no-take marine reserves had no bearing on ecosystem trajectory. Although conditions governing regime shift or recovery dynamics were diverse, pre-disturbance quantification of simple factors such as structural complexity and water depth accurately predicted ecosystem trajectories.

The multidimensional behaviors of flood change across Australia can be described by three distinct groups (i.e. no changes, increases and decreases in all flood properties), showing strong geographic cohesion. The geographical consistency between the changing patterns of flood properties and spatial patterns of vapor transport anomalies during the El Ni{\~{n}}o-Southern Oscillation (ENSO) positive phase could partly explain the geographic cohesion of flood changes.

The models (hereafter simply referred to as the “CIRCE models”) are a set of five coupled climate models composed by a high-resolution Mediterranean Sea coupled with a relatively high-resolution atmospheric component and a global ocean, which allow, for the first time, to explore and assess the role of the Mediterranean Sea and its complex, small-scale dynamics in the climate of the region. In particular, they make it possible to investigate the influence that local air-sea feedbacks might exert on the mechanisms responsible for climate variability and change in the European continent, Middle East and Northern Africa. In many regards, they represent a new and innovative approach to the problem of regionalization of climate projections in the Mediterranean region. The CIRCE models have been integrated from 1951 to 2050, with initial conditions obtained from a long spin-up run of the coupled systems. The simulations have been performed using observed radiative forcing (solar constant, greenhouse gases concentration and aerosol distribution) during the first half of the simulation period and the IPCC SRES A1B scenario during the second half (2001–2050). The projections indicate that remarkable changes in the Mediterranean region climate might occur already in the next few decades. A substantial warming (about 1.5°C in winter and almost 2°C in summer) and a significant decrease of precipitation (about 5{\%}) might affect the region in the 2021–2050 period compared to the reference period (1961–1990), in an A1B emission scenario. However, locally the changes might be even larger. In the same period, the projected surface net heat loss decreases, leading to a weaker cooling of the Mediterranean Sea by the atmosphere, whereas the water budget appears to increase, leading the basin to loose more water through its surface than in the past. The climate change projections obtained from the CIRCE models are overall consistent with the findings obtained in previous scenario simulations, such as PRUDENCE, ENSEMBLES and CMIP3. This agreement suggests that the results obtained from the climate projections are robust to substantial changes in the configuration of the models used to make the simulations. Finally, the CIRCE models produce a 2021–2050 mean steric sea-level rise that ranges between +6.6 cm and +11.6 cm, with respect to the period of reference. Within the CIRCE project the results obtained from these models have been used to investigate the climate of the Mediterranean region and its possible response to radiative forcing. Furthermore, the data have been made available for climate change impact studies that are included in the Regional Assessment of Climate Change in the Mediterranean that has been prepared in the context of the CIRCE project.}, address = {Dordrecht, The Netherlands}, author = {Gualdi, Silvio and Somot, Samuel and May, Wilhelm and Castellari, Sergio and D{\'{e}}qu{\'{e}}, Michel and Adani, Mario and Artale, Vincenzo and Bellucci, Alessio and Breitgand, Joseph S. and Carillo, Adriana and Cornes, Richard and Dell'Aquila, Alessandro and Dubois, Clotilde and Efthymiadis, Dimitrios and Elizalde, Alberto and Gimeno, Luis and Goodess, Clare M. and Harzallah, Ali and Krichak, Simon O. and Kuglitsch, Franz G. and Leckebusch, Gregor C. and L'H{\'{e}}v{\'{e}}der, Blandine and Li, Laurent and Lionello, Piero and Luterbacher, J{\"{u}}rg and Mariotti, Annarita and Navarra, Antonio and Nieto, Raquel and Nissen, Katrin M. and Oddo, Paolo and Ruti, Paolo and Sanna, Antonella and Sannino, Gianmaria and Scoccimarro, Enrico and Sevault, Florence and Struglia, Maria Vittoria and Toreti, Andrea and Ulbrich, Uwe and Xoplaki, Elena}, booktitle = {Regional Assessment of Climate Change in the Mediterranean: Volume 1: Air, Sea and Precipitation and Water}, doi = {10.1007/978-94-007-5781-3_3}, editor = {Navarra, A and Tubiana, L}, isbn = {978-94-007-5781-3}, pages = {53--118}, publisher = {Springer}, series = {Advances in Global Change Research vol. 50}, title = {{Future Climate Projections}}, url = {http://link.springer.com/10.1007/978-94-007-5781-3{\_}3}, volume = {50}, year = {2013} } @article{Guan2015, author = {Guan, Qingyu and Yang, Jing and Zhao, Shilei and Pan, Baotian and Liu, Chenglin and Zhang, Di and Wu, Tao}, doi = {10.1007/s00382-014-2321-3}, issn = {0930-7575}, journal = {Climate Dynamics}, month = {aug}, number = {3-4}, pages = {903--913}, title = {{Climatological analysis of dust storms in the area surrounding the Tengger Desert during 1960–2007}}, volume = {45}, year = {2015} } @article{Guan2017, abstract = {Airborne dust derived from desertification in northern China can be transported to East Asia and other regions, impairing human health and affecting the global climate. This study of northern China dust provides an understanding of the mechanism of dust generation and transportation. The authors used dust storm and climatological data from 129 sites and normalized difference vegetation index (NDVI) datasets in northern China to analyze spatiotemporal characteristics and determine the main factors controlling dust storms occurring during 1960–2007. Dust storm–prone areas are consistent with the spatial distribution of northern China deserts where the average wind speed (AWS) is more than 2 m s−1, the mean annual temperature (MAT) ranges from 5° to 10°C, and the mean annual precipitation (MAP) is less than 450 mm. Dust storms commonly occur on spring afternoons in a 3- to 6-h pattern. The three predominant factors that can affect DSF are the maximum wind speed, AWS, and MAT. During 1960–2007, dust storm frequency (DSF) in most regions of northern China fluctuated but had a decreasing trend; this was mainly caused by a gradual reduction in wind speed. The effect of temperature on DSF is complex, as positive and negative correlations exist simultaneously. Temperatures can affect source material (dust, sand, etc.), cyclone activity, and vegetation growth status, which influence the generation of dust storms. NDVI and precipitation are negatively correlated with DSF, but the effect is weak. Vegetation can protect the topsoil environment and prevent dust storm creation but is affected by the primary decisive influence of precipitation.}, author = {Guan, Qingyu; and Sun, Xiazhong; and Yang, Jing; and Pan, Baotian; and Zhao, Shilei; and Wang, Lei}, doi = {10.1175/JCLI-D-16-0795.1}, issn = {0894-8755}, journal = {Journal of Climate}, month = {sep}, number = {17}, pages = {6683--6700}, title = {{Dust Storms in Northern China: Long-Term Spatiotemporal Characteristics and Climate Controls}}, url = {http://journals.ametsoc.org/doi/10.1175/JCLI-D-16-0795.1}, volume = {30}, year = {2017} } @article{Gudmestad2018, author = {Gudmestad, Ove T.}, doi = {10.2495/EI-V1-N4-411-419}, issn = {2398-2640}, journal = {International Journal of Environmental Impacts: Management, Mitigation and Recovery}, month = {jan}, number = {4}, pages = {411--419}, title = {{The changing climate and the arctic coastal settlements}}, url = {http://www.witpress.com/doi/journals/EI-V1-N4-411-419}, volume = {1}, year = {2018} } @article{Gudmundsson2017, abstract = {Although there is overwhelming evidence showing that human emissions are affecting a wide range of atmospheric variables, it is not clear whether anthropogenic climate change is detectable in continental-scale freshwater resources.

The analysis shows that the previously observed amplification of the south (dry)-north (wet) contrast in pan-European river flow is captured by climate models only if human emissions are accounted for, although the models significantly underestimate the response. A regional analysis highlights that a strong and significant decrease is observed in the Mediterranean, generally along with a weak increase in northern Europe, whereas there is little change in transitional central Europe.

In this study, regional differences of the future permafrost changes are explored with respect to the regions (high altitude and high latitude, and in four countries) based on the surface frost index (SFI) model and multimodel and multiscenario data from the fifth phase of the Coupled Model Intercomparison Project (CMIP5). Results show the following: (1) Compared with seven other sets of driving data, Climatic Research Unit air temperature combined with Climate Forecast System Reanalysis snow data (CRU{\_}CFSR) yield a permafrost extent with the least absolute area bias and was thus used in the simulation. The SFI model, driven by CRU{\_}CFSR data climatology plus multimodel mean anomalies, produces a present-day (1986–2005) permafrost area of 15.45 × 106 km2 decade−1, which compares reasonably with observations of 15.24 × 106 km2 decade−1. (2) The high-altitude (Tibetan Plateau) permafrost area shows a larger decreasing percentage trend than the high-latitude permafrost area. This indicates that, in terms of speed, high-altitude permafrost thaw is faster than high-latitude permafrost, mainly due to the larger percentage sensitivity to rising air temperature of the high-altitude permafrost compared to the high-latitude permafrost, which is likely related to their thermal conditions. (3) Permafrost in China shows the fastest thaw, which is reflected by the percentage trend in permafrost area, followed by the United States, Russia, and Canada. These discrepancies are mainly linked to different percentage sensitivities of permafrost areas in these four countries to air temperature change. (4) In terms of the ensemble mean, permafrost areas in all regions are projected to decrease by the period 2080–2099. Under representative concentration pathway (RCP)4.5, permafrost retreats toward the Arctic, and the thaw in every region mainly occurs at the southern edge of the permafrost area. Under RCP8.5, almost no permafrost is expected to remain in China, the United States, and the Tibetan Plateau. Permafrost in Russia will remain mainly in the western part of the east Siberian Mountains, and permafrost in Canada will retreat to the north of 65°N. Possible uncertainties in this study are primarily attributed to the climate model's coarse horizontal resolution.

The lake ice phenology determined according to the simulated lake surface temperature is found consistent with that derived from satellite observations. For the Nam Co during the period 1978-2017, the freezing date has been delayed (reached up to 0.57 days/year), whereas the thawing date became earlier (-0.23 days/year). The trend of lake ice phenology is significantly correlated to the annual minimal lake surface and air temperature.

Electrical load variation and environmental changes affect the temperature in the transmission lines. For proper safety measurements these monitoring should be done on a continuous basis. Some of the ongoing temperature and sag monitoring methods that can be sited are the usage of stainless steel temperature probes, glass based sensors, thermocouples, RTDs, and Infrared sensors. However, all these methods have a disadvantage of having loosening of contacts. Cross sensitivity may also arise due to environmental contaminations. The disturbances caused by the different parameters can be stated as follows:- High temperature due to climate changes decreases the efficiency of electrical transmissions. Extreme weather conditions would increase the chances of failure rate of power lines. Temperature rise also results in an increase in thunder storms and results in the lightning strike of power lines. 2 degrees Celsius of temperature rise increases network losses by 0.04{\%}. It is also found that operation of the conductors on high temperature reduces the mechanical integrity of the overhead systems. It is also clear that cumulative damage occurs to the Aluminium metal in the overhead conductors. Hence, in order to overcome these disadvantages, we hypothise the introduction of MEMS (Micro Electro Mechanical Systems) technology through PLZT(L. This is a temperature sensor, which has numerous advantages over the existing ones. The thin film of Lead Lanthanum zirconate titanate (PLZT) will be coated on nickel foil by chemical solution deposition and this will be fabricated as sensor using MEMS technology.

Comprehensive knowledge of the solar resource and its future evolution is demanded by the energy sector. Solar resource and PV potential have been estimated in several studies using both the global climate model (GCM) and regional climate model (RCM), revealing a GCM–RCM discrepancy in the projected change over Europe. An increase in surface solar radiation (SSR) (and therefore in PV potential production) is projected by GCMs, whereas most RCM simulations project a decrease in SSR over Europe. In this work, we investigate the role of aerosol forcing in RCMs as a key explaining factor of this inconsistency. The results show that RCM simulations including evolving aerosols agree with GCMs in the sign and amplitude of the SSR change over Europe for mid-21st century projections (2021–2050 compared to 1971–2000 for representative concentration pathway climate change scenario RCP8.5). The opposite signal is projected by the rest of the RCMs. The amplitude of the changes likely depends on the RCM and on its aerosol forcing choice. In terms of PV potential, RCMs including evolving aerosols simulate an increase, especially in summer for Central and Eastern Europe, with maximum values reaching +10{\%} in some cases. This study illustrates the key role of the often-neglected aerosol forcing evolution in RCMs. It also suggests that it is important to be very careful when using the multi-model Coordinated Regional Climate Downscaling Experiment (CORDEX) projections for solar radiation and related variables, and argues for the inclusion of aerosol forcing evolution in the next generation of CORDEX simulations.}, author = {Guti{\'{e}}rrez, C and Somot, S and Nabat, P and Mallet, M and Corre, L and van Meijgaard, E and Perpi{\~{n}}{\'{a}}n, O and Gaertner, M {\'{A}}}, doi = {10.1088/1748-9326/ab6666}, issn = {1748-9326}, journal = {Environmental Research Letters}, number = {3}, pages = {34035}, publisher = {IOP Publishing}, title = {{Future evolution of surface solar radiation and photovoltaic potential in Europe: investigating the role of aerosols}}, url = {http://dx.doi.org/10.1088/1748-9326/ab6666}, volume = {15}, year = {2020} } @article{Habeeb2015, author = {Habeeb, Dana and Vargo, Jason and Stone, Brian}, doi = {10.1007/s11069-014-1563-z}, issn = {0921-030X}, journal = {Natural Hazards}, month = {apr}, number = {3}, pages = {1651--1665}, publisher = {Springer Netherlands}, title = {{Rising heat wave trends in large US cities}}, url = {http://link.springer.com/10.1007/s11069-014-1563-z}, volume = {76}, year = {2015} } @article{Hackenbruch2017, abstract = {Municipalities are important actors in the field of local climate change adaptation.

As a consequence, many still existing glacier and permafrost landscapes probably transform within decades into new landscapes of bare bedrock, loose debris, sparse vegetation, numerous new lakes and steep slopes with slowly degrading permafrost. These new landscapes are likely to persist for centuries if not millennia to come. During variable but mostly extended future time periods, such new landscapes will be characterized by pronounced disequilibria within their geo- and ecosystems. This especially involves long-term stability reduction of steep/icy mountain slopes as a slow and delayed reaction to stress redistribution following de-buttressing by vanishing glaciers and to changes in mechanical strength and hydraulic permeability caused by permafrost degradation. Thereby, the probability of far-reaching flood waves from large mass movements into lakes systematically increases with the formation of many new lakes and systems of lakes in close neighborhood to, or even directly at the foot of, so-affected slopes. Results of recent studies in the Swiss Alps are reviewed and complemented with examples from the Cordillera Blanca in Peru and the Mount Everest region in Nepal. Hot spots of future hazards from potential flood waves caused by large rock falls into new lakes can already now be recognized. To this end, integrated spatial information on glacier/permafrost evolution and lake formation can be used together with scenario-based models for rapid mass movements, impact waves and flood propagation. The resulting information must then be combined with exposure and vulnerability considerations related to settlements and infrastructure. This enables timely planning of risk reduction options. Such risk reduction options consist of two components: Mitigation of hazards, which in the present context are due to effects from climate change, and reduction in consequences, which result from societal conditions and changes. Hazard mitigation may include artificial lake drainage or lake-level lowering and flood retention, optimally in connection with multipurpose structures for hydropower production and/or irrigation. Reduction in damage potential (exposure, vulnerability) can be accomplished by installing early-warning systems, adapting spatial planning and/or by improving preparedness of local people and institutions.}, author = {Haeberli, Wilfried and Schaub, Yvonne and Huggel, Christian}, doi = {10.1016/j.geomorph.2016.02.009}, issn = {0169555X}, journal = {Geomorphology}, keywords = {Climate change,Floods,Glaciers,Hazard,High mountains,Impact waves,New lakes,Permafrost,Risk}, month = {sep}, pages = {405--417}, publisher = {Elsevier B.V.}, title = {{Increasing risks related to landslides from degrading permafrost into new lakes in de-glaciating mountain ranges}}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0169555X16300381}, volume = {293}, year = {2017} } @article{GebremeskelHaile2020a, abstract = {Understanding historical patterns of changes in drought is essential for drought adaptation and mitigation.

Here, we provided a comprehensive spatiotemporal drought pattern analysis during the period of 1964–2015 over the GHA. The Standardised Precipitation-Evapotranspiration Index (SPEI) at various timescales (1 month (SPEI-01), 3 month (SPEI-03), 6 month (SPEI-06), and 12 month (SPEI-12)) was used to investigate drought patterns on a monthly, seasonal, and interannual basis. The results showed that despite regional differences, an overall increasing tendency of drought was observed across the GHA over the past 52 yr, with trends of change of −0.0017 yr−1, −0.0036 yr−1, −0.0031 yr−1, and −0.0023 yr−1 for SPEI-01, SPEI-03, SPEI-06, and SPEI-12, respectively.

Our simple, intuitive approach emphasizes climate connectivity, and enables us to model over 12 times as many species as previous studies(5,6). We find that range expansions prevail over contractions for both RCPs up to 2100, producing a net local increase in richness globally, and temporal changes in composition, driven by the redistribution rather than the loss of diversity. Conversely, widespread invasions homogenize present-day communities across multiple regions. High extirpation rates are expected regionally (for example, Indo-Pacific), particularly under RCP8.5, leading to strong decreases in richness and the anticipated formation of no-analogue communities where invasions are common. The spatial congruence of these patterns with contemporary human impacts(7,8) highlights potential areas of future conservation concern.

To predict the effect of climate and land-use changes on airborne pollen concentrations, we used two comprehensive modelling frameworks accounting for all these factors under high-end and moderate climate and land-use change scenarios. We estimate that by 2050 airborne ragweed pollen concentrations will be about 4 times higher than they are now, with a range of uncertainty from 2 to 12 largely depending on the seed dispersal rate assumptions. About a third of the airborne pollen increase is due to on-going seed dispersal, irrespective of climate change. The remaining two-thirds are related to climate and land-use changes that will extend ragweed habitat suitability in northern and eastern Europe and increase pollen production in established ragweed areas owing to increasing CO2.

A widespread gap between available information and farmers' needs is associated with entrenched seasonal forecast convention and obstacles to using observational data. Scalable innovations for producing more locally relevant historical and forecast climate information for farm decision-making are beginning to be adopted. Structured participatory communication processes help farmers relate complex climate information to their experience, and integrate it into their management decisions. Promising efforts to deliver rural climate services strategically combine communication channels that include participatory processes embedded in existing agricultural advisory systems, and innovations in interactive broadcast media. Efforts to engage farmers in co-production of climate services improve delivery to farmers and dialogue among stakeholders, but often with little impact on the usability of available information. We discuss challenges and options for capturing farmers' evolving demands, and aggregating and incorporating this information into iterative improvements to climate services at a national scale. We find evidence that key weaknesses in the supply and the demand sides of climate services continue to reinforce each other to impede progress toward meeting farmers' needs at scale across Africa. Six recommendations target these weaknesses: (1) change the way seasonal forecasts are produced and presented regionally and nationally, (2) use merged gridded data as a foundation for national climate information products, (3) remove barriers to using historical data as a public good, (4) mobilize those who work on the demand side of climate services as an effective community of practice, (5) collectively assess and improve tools and processes for communicating climate information with rural communities, and (6) build iterative co-production processes into national climate service frameworks.}, author = {Hansen, James W. and Vaughan, Catherine and Kagabo, Desire M. and Dinku, Tufa and Carr, Edward R. and K{\"{o}}rner, Jana and Zougmor{\'{e}}, Robert B.}, doi = {10.3389/fsufs.2019.00021}, issn = {2571-581X}, journal = {Frontiers in Sustainable Food Systems}, month = {apr}, pages = {21}, publisher = {Frontiers Media SA}, title = {{Climate Services Can Support African Farmers' Context-Specific Adaptation Needs at Scale}}, url = {https://www.frontiersin.org/article/10.3389/fsufs.2019.00021/full}, volume = {3}, year = {2019} } @article{Hanzer2018, abstract = {2500 m a.s.l.) until the end of the century.

Not coincidentally, the single hottest year on record, 2015, also broke records for area burned by wildfire in the United States (Fig. 1 A and B ), eclipsing the previous high mark set just one decade prior (2). Scientists have known for some time that climate is a key driver of forest fires; records from the past and present (3⇓–5) provide strong evidence that warmer temperatures are associated with spikes in fire activity. Therefore, recent increases in wildfire activity as the planet warms are not a surprise. However, just how much of the recent increases in forest fire activity can be attributed to human-caused climate change vs. natural variability in climate? This question has profound scientific, management, and policy implications, yet answers have thus far remained elusive. In PNAS, Abatzoglou and Williams (6) present strong evidence that human-caused climate change is increasing wildfire activity across wide swaths of forested land in the western United States. They demonstrate that human-caused climate change has lengthened the annual fire season (i.e., the window of time each year with weather that is conducive to forest fires) and, since 1984, has doubled the cumulative area in the western United States that would have otherwise burned due to natural climate forcing alone. {\ldots} [↵][1]1Email: brianjamesharvey{\{}at{\}}gmail.com.

Here we propose that trends in the northward transport of Antarctic sea ice are a major contributor to these changes. Using satellite observations supplemented by sea-ice reconstructions, we estimate that wind-driven northward freshwater transport by sea ice increased by 20 ± 10 per cent between 1982 and 2008. The strongest and most robust increase occurred in the Pacific sector, coinciding with the largest observed salinity changes. We estimate that the additional freshwater for the entire northern sea-ice edge entails a freshening rate of '0.02 ± 0.01 grams per kilogram per decade in the surface and intermediate waters of the open ocean, similar to the observed freshening. The enhanced rejection of salt near the coast of Antarctica associated with stronger sea-ice export counteracts the freshening of both continental shelf and newly formed bottom waters due to increases in glacial meltwater. Although the data sources underlying our results have substantial uncertainties, regional analyses and independent data from an atmospheric reanalysis support our conclusions. Our finding that northward sea-ice freshwater transport is also a key determinant of the mean salinity distribution in the Southern Ocean further underpins the importance of the sea-ice-induced freshwater flux. Through its influence on the density structure of the ocean, this process has critical consequences for the global climate by affecting the exchange of heat, carbon and nutrients between the deep ocean and surface waters.}, author = {Haumann, F.

The uncertainty in ToE is at least 30 years in the regions examined, and as much as 60 years in some regions.

OBJECTIVES: We aimed to illuminate the relation between ambient temperature and bikeshare usage and to project how climate change-induced increasing ambient temperatures may influence active transportation in New York City. METHODS: The analysis leverages Citi Bike{\textregistered} bikeshare data to estimate participation in outdoor bicycling in New York City. Exposure–response functions are estimated for the relation between daily temperature and bike usage from 2013 to 2017. The estimated exposure–response relation is combined with temperature outputs from 21 climate models (run with emissions scenarios RCP4.5 and RCP8.5) to explore how climate change may influence future bike utilization. RESULTS: Estimated daily hours and distance ridden significantly increased as temperatures increased, but then declined at temperatures above 26–28°C. Bike usage may increase by up to 3.1{\%} by 2070 due to climate change. Future ridership increases during the winter, spring, and fall may more than offset future declines in summer ridership. DISCUSSION: Evidence suggesting nonlinear impacts of rising temperatures on health-promoting bicycle ridership demonstrates how challenging it is to anticipate the health consequences of climate change. We project increases in bicycling by mid-century in NYC, but this trend may reverse as temperatures continue to rise further into the future. https://doi.org/10.1289/EHP4039.}, author = {Heaney, Alexandra K. and Carri{\'{o}}n, Daniel and Burkart, Katrin and Lesk, Corey and Jack, Darby}, doi = {10.1289/EHP4039}, issn = {0091-6765}, journal = {Environmental Health Perspectives}, month = {mar}, number = {3}, pages = {037002}, publisher = {Public Health Services, US Dept of Health and Human Services}, title = {{Climate Change and Physical Activity: Estimated Impacts of Ambient Temperatures on Bikeshare Usage in New York City}}, url = {https://ehp.niehs.nih.gov/doi/10.1289/EHP4039}, volume = {127}, year = {2019} } @misc{Hellberg2016, abstract = {According to the Intergovernmental Panel on Climate Change (IPCC), warming of the climate system is unequivocal.

Providing robust and actionable climate information at regional scales relies on the downscaling of global climate model data and its translation into impact-relevant information. The New South Wales/Australian Capital Territory Regional Climate Modelling (NARCliM) project contains downscaled climate data over all of Australia at a 50 km resolution, with ensembles of simulations for the recent past (1990–2009), near future (2020–2039) and far future (2060–2079). Here we calculate and examine sector-relevant indices of climate extremes recommended by the Expert Team on Sector-specific Climate Indices (ET-SCI). We demonstrate the utility of NARCliM and the ET-SCI indices in understanding how future changes in climate extremes could impact aspects of the health and agricultural sectors in Australia. Consistent with previous climate projections, our results indicate that increases in heat and drought related extremes throughout the 21st century will occur. In the far future, maximum day time temperatures are projected to increase by up to 3.5 °C depending on season and location. The number of heatwaves and the duration of the most intense heatwaves will increase significantly in the near and far future, with greater increases in the north than south. All capital cities are projected to experience at least a tripling of heatwave days each year by the far future, compared to the recent past. Applying published heat-health relationships to projected changes in temperature shows that increases in mortality due to high temperatures for all cities examined would occur if projected future climates occurred today. Drought and the number of days above 30 °C are also projected to increase over the major wheat-growing regions of the country, particularly during spring when sensitivity of wheat to heat stress is greatest. Assuming no adaptation or acclimatisation, published statistical relationships between drought and national wheat yield suggest that national yields will have a less than one quarter chance of exceeding the annual historical average under far future precipitation change (excluding impacts of future temperature change and CO2fertilization).

The events were the 2016 record global heat, the heat across Asia, as well as a marine heat wave off the coast of Alaska. While these results are novel, they were not unexpected. Climate attribution scientists have been predicting that eventually the influence of human-caused climate change would become sufficiently strong as to push events beyond the bounds of natural variability alone. It was also predicted that we would first observe this phenomenon for heat events where the climate change influence is most pronounced. Additional retrospective analysis will reveal if, in fact, these are the first events of their kind or were simply some of the first to be discovered. Last year, the editors emphasized the need for additional papers in the area of “impacts attribution” that investigate whether climate change's influence on the extreme event can subsequently be directly tied to a change in risk of the socio-economic or environmental impacts. Several papers in this year's report address this challenge, including Great Barrier Reef bleaching, living marine resources in the Pacific, and ecosystem productivity on the Iberian Peninsula. This is an increase over the number of impact attribution papers than in the past, and are hopefully a sign that research in this area will continue to expand in the future.

Finally, lake ice conditions are projected to the end of the 21st century, using an optimal ensemble of Global Climate Model outputs for two different climate change scenarios (RCP4.5, RCP8.5). Heavy ice seasons no longer occur as early as the 2050s under both RCP4.5 and RCP8.5. Whereas, very light ice seasons go from being an extreme in the baseline period (10{\%}), to the dominant characterization of Lake Ontario ice conditions by the 2080s, for both RCP4.5 (73{\%}) and RCP8.5 (100{\%}).}, author = {Hewer, Micah J. and Gough, William A.}, doi = {10.1016/j.jglr.2019.10.006}, issn = {03801330}, journal = {Journal of Great Lakes Research}, keywords = {Climate change projections,Freezing-degree days,Hindcasting,Lake ice,Melting-degree days,Winter temperatures}, month = {dec}, number = {6}, pages = {1080--1089}, publisher = {International Association of Great Lakes Research}, title = {{Lake Ontario ice coverage: Past, present and future}}, volume = {45}, year = {2019} } @article{Hewitson2017a, abstract = {The climate change agenda is populated by actors and agencies with different objectives, values, and motivations, yet many seek decision scale climate information to inform policy and adaptation responses. A central element of this network of activity is the climate information website (CIW) that has seen a rapid and organic growth, yet with variable content and quality, and unfettered by any code of practice. This builds an ethical?epistemic dilemma that warrants assessment as the presence of CIWs contribute to real-world consequences and commitment. This study considers the context of CIW growth, and reviews a representative sample of CIWs to draw out key issues for consideration in CIW development. We assess content, function, and use-case value through a dual approach of a typology and user experience narratives to evaluate the general efficacy of a CIW. The typology reveals strong contrasts in content, complicated interfaces, and an overload of choice making it difficult to converge on a stable outcome. The narratives capture user experience and highlight barriers that include navigation difficulties, jargon laden content, minimal or opaque guidance, and inferred information without context about uncertainty and limits to skill. This illuminates four concerns: (1) the ethics of information provision in a context of real-world consequences; (2) interfaces that present barriers to achieving robust solutions; (3) weak capacity of both users and providers to identify information of value from the multimodel and multimethod data; and (4) inclusion of data that infer skill.

T here is growing acceptance that the climate is changing, and increasing recognition and realization of the socio-economic benefits arising from using climate information to better inform decisions and policies across a wide range of sectors 1–3 . Climate services are being developed worldwide for an expanding group of decision-makers and policymakers to enable society to better manage the risks and opportunities arising from changes in climate, especially for those who are most vulnerable to climate-related hazards. The global community is actively addressing this through the United Nation's Global Framework for Climate Services (GFCS) 4,5 . An essential element of any climate service is for there to be effective engagement between the users and the providers of the service. However, there is growing recognition that this interface between the users and providers is the least-developed aspect of climate services 5 , and therefore urgently needs improving. An international team of experts has been enlisted under the World Meteorological Organization's (WMO) Commission for Climatology to both provide recommendations for good practice and successful strategies for effective and improved engagement. The recommendations were made by gathering and assessing examples of good uptake and use of climate information through effective user– provider engagement. Each example was documented using a common structure, identifying who is involved in the engagement, how the engagement is conducted, what it aims to achieve, and any recommendations for good practice. The examples represent a variety of approaches adopted across key climate-sensitive sectors, and across a range of timescales (the past and the future on timescales from monthly and seasonal through to multi-decadal) and spacial scales (global, regional, national and local, with wide geographic spread globally).

We refer to the provision and use of such information as climate services. Established programs of research and operational activities are improving observations and climate monitoring, our understanding of climate processes, climate variability and change, and predictions and projections of the future climate. Delivering climate information (including data and knowledge) in a way that is usable and useful for decision-makers has had less attention, and society has yet to optimally benefit from the available information. While weather services routinely help weather-sensitive decision-making, similar services for decisions on longer time scales are less well established. Many organizations are now actively developing climate services, and a growing number of decision-makers are keen to benefit from such services.

In addition to the benefits, we also document some challenges that have emerged, along with ways of alleviating them.

Tavg data from stations and complementary gridded datasets at 50 km resolution were used to generate a high-resolution (5 km grid) dataset for Central America from 1970 to 1999. A highresolution P dataset was used along with the new Tavg dataset to study climate variability and a climate change application. Consistently with other studies, it was found that the 1970-1999 trends in P are generally non-significant, with the exception of a few small locations. In the case of Tavg, there were significant warming trends in most of Central America, and cooling trends in Honduras and northern Panama. When the sea surface temperature anomalies between the Tropical Pacific and the Tropical Atlantic have different (same) sign, they are a good indicator of the sign of P (Tavg) annual anomalies. Even with non-significant trends in precipitation, the significant warming trends in Tavg in most of Central America can have severe consequences in the hydrology and water availability of the region, as the warming would bring increases in evapotranspiration, drier soils and higher aridity.}, author = {Hidalgo, H.G. and Alfaro, E.J. and Quesada-Montano, B.}, doi = {10.1007/s10584-016-1786-y}, isbn = {1573-1480}, issn = {0165-0009}, journal = {Climatic Change}, month = {mar}, number = {1}, pages = {13--28}, title = {{Observed (1970–1999) climate variability in Central America using a high-resolution meteorological dataset with implication to climate change studies}}, url = {http://link.springer.com/10.1007/s10584-016-1786-y}, volume = {141}, year = {2017} } @article{Hill2014, author = {Hill, Ryan A. and Hawkins, Charles P. and Jin, Jiming}, doi = {10.1007/s10584-014-1174-4}, issn = {0165-0009}, journal = {Climatic Change}, month = {aug}, number = {3-4}, pages = {399--412}, publisher = {Springer Netherlands}, title = {{Predicting thermal vulnerability of stream and river ecosystems to climate change}}, url = {http://link.springer.com/10.1007/s10584-014-1174-4}, volume = {125}, year = {2014} } @article{Hincapie2013, abstract = {Vegetation change under two climate change scenarios in different periods of the 21 st Century are modeled for Colombia.

Their growth and biochemical composition are affected by surrounding environmental conditions, including temperature, which continues to increase as a result of climate warming. Increasing water temperatures may negatively impact the production of EFA by phytoplankton through the process of homeoviscous adaptation. To investigate this, we conducted an exploratory data synthesis with 952 fatty acid (FA) profiles from six major groups of marine and freshwater phytoplankton. Temperature was strongly correlated with a decrease in the proportion of n-3 long-chain polyunsaturated FA (LC-PUFA) and an increase in omega-6 FA and saturated FA. Based on linear regression models, we predict that global n-3 LC-PUFA production will be reduced by 8.2{\%} for eicosapentaenoic acid (EPA) and 27.8{\%} for docosahexaenoic acid (DHA) with an increase in water temperature of 2.5 °C. Using a previously published estimate of the global production of EPA by diatoms, which contribute to most of the world's supply of EPA, we predict a loss of 14.2 Mt of EPA annually as a result of ocean warming. The n-3 LC-PUFA are vitally important for an array of key physiological functions in aquatic and terrestrial organisms, and these FA are mainly produced by phytoplankton. Therefore, reduced production of these EFA, as a consequence of climate warming, is predicted to negatively affect species that depend on these compounds for optimum physiological function.

A variety of impacts have been associated with these anomalous events, including shifts in species ranges, local extinctions and economic impacts on seafood industries through declines in important fishery species and impacts on aquaculture. Extreme temperatures are increasingly seen as important influences on biological systems, yet a consistent definition of MHWs does not exist. A clear definition will facilitate retrospective comparisons between MHWs, enabling the synthesis and a mechanistic understanding of the role of MHWs in marine ecosystems. Building on research into atmospheric heatwaves, we propose both a general and specific definition for MHWs, based on a hierarchy of metrics that allow for different data sets to be used in identifying MHWs. We generally define a MHW as a prolonged discrete anomalously warm water event that can be described by its duration, intensity, rate of evolution, and spatial extent. Specifically, we consider an anomalously warm event to be a MHW if it lasts for five or more days, with temperatures warmer than the 90th percentile based on a 30-year historical baseline period.

Here, the synoptic seasons? definition of Alpert, Osetinsky, Ziv, and Shafir (2004a) was applied to an ensemble of eight Coupled Model Inter-Comparison Project phase 5 (CMIP5) models, under RCP8.5 and RCP4.5 scenarios, to predict the changes in the lengths of EM seasons during the 21st century. It is shown that the ensemble adequately represents the annual cycle of the main synoptic systems over the EM. The analysis further suggests that at the end of the 21st century, the duration of the synoptic summer, characterized by the occurrence of the Persian Trough, is expected to be lengthened by 49{\%}, while the synoptic winter, characterized by the occurrence of the Cyprus Low, is expected to be shortened by 56{\%} under the RCP8.5 scenario.

We analyzed historical trends by basin type: minimally altered basins, regulated basins (substantial reservoir storage but low urbanization), and urbanized basins (with low reservoir storage). Although many peak-flow magnitude changes were found in the last century across the conterminous United States, the trend magnitude and direction vary strongly by basin type and region. In general, there was a low percentage of significant increases and decreases for minimally altered basins while many regulated basins had significant decreases and the limited number of urbanized basins with long-term record showed a high percentage of increases. For urbanized basins, which are concentrated in the Northeast and Midwest, trend magnitude was significantly correlated with the amount of basin urbanization. For all basins regardless of type, parts of the Northeast quadrant of the U.S. had high concentrations of basins with large and significant increases while parts of the Southwest quadrant had high concentrations of basins with large and significant decreases. Basin regulation appears to have heavily influenced the decreasing trends in the Southwest quadrant; there were many large decreases for this basin type despite overall increases in heavy precipitation in this area.

Warm-water coral reefs, for example, occupy shallow sunlit, warm and alkaline waters in order to grow and calcify at the high rates necessary to build and maintain their calcium carbonate structures. At deeper locations (40 – 150 m), “mesophotic” (low light) coral reefs accumulate calcium carbonate at much lower rates (if at all in some cases) yet remain important as habitat for a wide range of organisms, including those important for fisheries. Finally, even deeper, down to 2000 m or more, the so-called ‘cold-water' coral reefs are found in the dark depths. Despite their importance, coral reefs are facing significant challenges from human activities including pollution, over-harvesting, physical destruction, and climate change. In the latter case, even lower greenhouse gas emission scenarios (such as Representative Concentration Pathway RCP 4.5) are likely drive the elimination of most warm-water coral reefs by 2040-2050. Cold-water corals are also threatened by warming temperatures and ocean acidification although evidence of the direct effect of climate change is less clear. Evidence that coral reefs can adapt at rates which are sufficient for them to keep up with rapid ocean warming and acidification is minimal, especially given that corals are long-lived and hence have slow rates of evolution. Conclusions that coral reefs will migrate to higher latitudes as they warm are equally unfounded, with the observations of tropical species appearing at high latitudes ‘necessary but not sufficient' evidence that entire coral reef ecosystems are shifting. On the contrary, coral reefs are likely to degrade rapidly over the next 20 years, presenting fundamental challenges for the 500 million people who derive food, income, coastal protection, and a range of other services from coral reefs.

We investigate a series of inundation events which occurred across the western Pacific over several consecutive days during December 2008, causing severe impacts to five Pacific Island nations. These events were not associated with commonly identified causes: tropical cyclones or unusually large astronomical tides. Instead, the dissipation of wind-waves generated by distant extra-tropical cyclones (swell) was the main cause, although regional sea level variability, including recent accelerated rise, significantly contributed to the severity of impact experienced at many locations. The implication of recent sea level rise in the severity of these events suggests that episodic swell will increasingly cause major impacts of the nature described herein, although such impacts will continue to be modulated by El Ni{\~{n}}o/Southern Oscillation (ENSO) variability in the region. Significantly, tide gauges recorded little evidence of extreme sea levels during the event, implying that causes of extreme sea levels inferred from tide gauge analysis are unlikely to include this important cause of inundation. Therefore, any assessment of inundation risk predicated on tide gauge information (as well as larger scale sea level information such as satellite altimetry) may fail at many locations in the Pacific. To be accurate, such efforts must include information on the relationship between wave climate, wave forecasts and local extreme water levels. Further development of related early warning systems will become more pertinent as modern SLR continues to add to the magnitude of extremes. {\textcopyright} 2013 Published by Elsevier B.V.}, author = {Hoeke, Ron K. and McInnes, Kathleen L. and Kruger, Jens C. and McNaught, Rebecca J. and Hunter, John R. and Smithers, Scott G.}, doi = {10.1016/j.gloplacha.2013.06.006}, isbn = {0921-8181}, issn = {09218181}, journal = {Global and Planetary Change}, keywords = {Disaster risk,El Ni{\~{n}}o/Southern Oscillation (ENSO),Flooding,Inundation,Pacific,Sea level,Storms,Waves}, month = {sep}, pages = {128--138}, publisher = {The Authors}, title = {{Widespread inundation of Pacific islands triggered by distant-source wind-waves}}, url = {http://dx.doi.org/10.1016/j.gloplacha.2013.06.006 https://linkinghub.elsevier.com/retrieve/pii/S0921818113001483}, volume = {108}, year = {2013} } @article{Hof2016, abstract = {With the expected rising temperatures, outbreaks of insect pests may be more frequent, which can have large consequences on forest ecosystems and may therefore negatively affect the forestry sector.

By adopting these, the IPCC would facilitate local decision-making on climate change and provide a systematic review of how its reports are being used locally.

Observed and modelled landfast ice thickness variability and trends spanning more than 5 decades within the Canadian Arctic Archipelago (CAA) are summarized. The observed sites (Cambridge Bay, Resolute, Eureka and Alert) represent some of the Arctic's longest records of landfast ice thickness. Observed end-of-winter (maximum) trends of landfast ice thickness (1957–2014) were statistically significant at Cambridge Bay (−4.31 ± 1.4 cm decade−1), Eureka (−4.65 ± 1.7 cm decade−1) and Alert (−4.44 ± 1.6 cm −1) but not at Resolute. Over the 50+-year record, the ice thinned by ∼ 0.24–0.26 m at Cambridge Bay, Eureka and Alert with essentially negligible change at Resolute. Although statistically significant warming in spring and fall was present at all sites, only low correlations between temperature and maximum ice thickness were present; snow depth was found to be more strongly associated with the negative ice thickness trends. Comparison with multi-model simulations from Coupled Model Intercomparison project phase 5 (CMIP5), Ocean Reanalysis Intercomparison (ORA-IP) and Pan-Arctic Ice-Ocean Modeling and Assimilation System (PIOMAS) show that although a subset of current generation models have a "reasonable" climatological representation of landfast ice thickness and distribution within the CAA, trends are unrealistic and far exceed observations by up to 2 orders of magnitude. ORA-IP models were found to have positive correlations between temperature and ice thickness over the CAA, a feature that is inconsistent with both observations and coupled models from CMIP5.}, author = {Howell, Stephen E.

By best estimates, the present-day Caribbean formed between 200 and 130 million years (MY) ago, when North and South America pushed apart and Pacific crust moved northeastward (Pindell 1994). By late Cretaceous time (80 MY: Fig. 7.1), Caribbean plate motion was starting to turn eastward, the Aves Ridge (presently southeast of St. Croix ) was forming, and rudistid molluscs were the dominant reef fauna throughout the region (Fig. 7.2). By Oligocene time, the geography of the Caribbean looked much like it is today, and the Greater Antilles lay along a major fault separating the Caribbean and Atlantic plates. Caribbean coral reefs were populated by a much more cosmopolitan fauna than what exists today (Frost 1977; Frost and Weiss 1979). Throughout the Miocene, the Greater Antilles were being torn apart and twisted by both tensional and compressive forces between the opposing Caribbean and Atlantic Plates (Pindell and Barrett 1990; Masson and Scanlon 1991). This has resulted in a leftlateral offset of similar formations on different islands (e.g., the Ponce/Aymamon Formations on Puerto Rico and the Kingshill on St. Croix), as well as counterclockwise rotation of many individual islands (Reid et al. 1991; Gill et al. 2002).

Additionally, the possible impact of climatic changes on the energy output of a sample 2.5-MW turbine is discussed. GCM-driven RCM simulations capture the behavior and variability of current wind energy indices, even though some differences exist when compared with reanalysis-driven RCM simulations. Toward the end of the twenty-first century, projections show significant changes of energy density on annual average across Europe that are substantially stronger in seasonal terms. The emergence time of these changes varies from region to region and season to season, but some long-term trends are already statistically significant in the middle of the twenty-first century. Over northern and central Europe, the wind energy potential is projected to increase, particularly in winter and autumn. In contrast, energy potential over southern Europe may experience a decrease in all seasons except for the Aegean Sea. Changes for wind energy output follow the same patterns but are of smaller magnitude.

After eight months, an exposure of 6 °C-weeks or more drove an unprecedented, regional-scale shift in the composition of coral assemblages, reflecting markedly divergent responses to heat stress by different taxa. Fast-growing staghorn and tabular corals suffered a catastrophic die-off, transforming the three-dimensionality and ecological functioning of 29{\%} of the 3,863 reefs comprising the world's largest coral reef system.

So far, the only usable proxies for water availability have been time-lagged precipitation anomalies and drought indices3–5, owing to a lack of direct observations. Here, we use recent observations of terrestrial water storage changes derived from satellite gravimetry7 to investigate terrestrial water effects on carbon cycle variability at global to regional scales. We show that the CO2 growth rate is strongly sensitive to observed changes in terrestrial water storage, drier years being associated with faster atmospheric CO2 growth. We demonstrate that this global relationship is independent of known temperature effects and is underestimated in current carbon cycle models.

Here, we estimate the time of emergence (TOE) of temperature and wet-bulb temperature (Tw), a better indication of heat stress, using fine-scale, long-term regional climate model projections under the RCP2.6 and RCP8.5 scenarios across six different domains. Differently from previous studies, the TOE is determined using three methods applied on impact-relevant variables: two different signal-to-noise frameworks based on summer mean temperature and Tw and a statistical test to identify significant differences in daily extreme distributions. The TOE response to RCP2.6 and RCP8.5 with respect to the end of 20th century variability differs significantly regardless of which TOE metric is applied. For summer mean temperature, the land fraction reaching TOE is expected to exceed 90{\%} by the 2050s under the RCP8.5, whereas the increase rate of land exposure to TOE tends to stagnate over time under the RCP2.6 so that more than 40{\%} of land will not experience TOE by the end of the 21st century. Compared to temperature, the TOE of Tw is reached earlier in most of the wet tropics but is delayed in hot and dry regions because of the nonlinear response of Tw to humidity. For both temperature and Tw, the TOE appears earlier in regions with low baseline variability, such as in the tropics.

Factors controlling variations in annual S/P ratio and their relationships with large-scale atmospheric circulation patterns (ACPs) were also studied. The results show that there were significant declines in annual S/P ratio during 1909–2008, which were principally attributable to century-long decreasing trends in annual snowfall (S) in Finland. These reductions in annual S were predominantly controlled by both annual rainfall (R) and snowfall-day temperature (ST) in the south, annual ST in the centre, and annual R in the north. However, dividing the 100-year study period into an early (1909–1958) and late (1959–2008) periods revealed non-linear trend behaviours in annual S and consequently annual S/P ratio during 1909–2008.

We analysed bibliographical sources and satellite images to document the glacier and permafrost dynamics that have caused socio-economic damages in this region in historic time (including glacial lake outburst floods, ice and rock-ice avalanches and lahars) to unravel their causes and geomorphological impacts. In the extratropical Andes, at least 15 ice-dammed lakes and 16 moraine-dammed lakes have failed since the eighteenth century, causing dozens of floods. Some floods rank amongst the largest events ever recorded (5000×106m3 and 229×106m3, respectively). Outburst flood frequency has increased in the last three decades, partially as a consequence of long-term (decades to centuries) climatic changes, glaciers shrinkage, and lake growth. Short-term (days to weeks) meteorological conditions (i.e. intense and/or prolonged rainfall and high temperature that increased meltwater production) have also triggered outburst floods and mass movements. Enormous mass failures of glaciers and permafrost ({\textgreater} 10×106m3) have impacted lakes, glaciers, and snow-covered valleys, initiating chain reactions that have ultimately resulted in lake tsunamis and far-reaching ({\textgreater} 50km) flows.

Seven research institutes from Europe and Turkey integrated their competencies to provide a cross-sectoral assessment of the potential impacts at a pan-European scale. The initial findings of this initiative are presented and key messages communicated. The approach is to select periods based on global warming thresholds rather than the more typical approach of selecting time periods (e.g., end of century). The results indicate that the world is likely to pass the +1.5°C threshold in the coming decades. Cross-sectoral dimensions are taken into account to show the impacts of global warming that occur in parallel in more than one sector. Also, impacts differ across sectors and regions. Alongside the negative impacts for certain sectors and regions, some positive impacts are projected. Summer tourism in parts of Western Europe may be favored by climate change; electricity demand decreases outweigh increases over most of Europe and catchment yields in hydropower regions will increase.

Our study area is western Canada (British Columbia and Alberta) and we consider both an historical control period (1990–2000) and three future time periods (2020–2030, 2050–2060, and 2080–2090). The historical data used to calibrate the DBS procedure comprises weather station data and weather from the North American Regional Reanalysis (NARR), whereas the future climate projections are the output of three regional climate models, corresponding to different model parameterizations and downscaled from the NCAR Community Earth System Model under the RCP 8.5 scenario. By fitting a truncated Weibull distribution to observed and modeled FWI values, our method is able to reproduce historical extremes in fire weather indices as determined by the distribution of annual potential spread days, which are defined as days with FWI values greater than 19. Moreover, by calibrating the DBS procedure with gridded reanalysis data as well as station observations, we are able to project future spread day distributions over the entire study area. The results of this study show the DBS procedure leads to a greater number of projected annual spread days at most locations compared with estimates using the uncorrected model output, and that all three RCM models show positive increases in potential annual spread days for the 2050–2060 and 2080–2090 time periods.}, author = {Jain, Piyush and Tye, Mari R. and Paimazumder, Debasish and Flannigan, Mike}, doi = {10.1007/s10584-020-02865-5}, issn = {15731480}, journal = {Climatic Change}, keywords = {Index-Spread days-Statistical downscaling-Bias cor,Weather,Wildfires-Fire}, month = {nov}, number = {1}, pages = {189--216}, publisher = {Springer Science and Business Media B.V.}, title = {{Downscaling fire weather extremes from historical and projected climate models}}, url = {https://doi.org/10.1007/s10584-020-02865-5}, volume = {163}, year = {2020} } @article{Jakob2016, abstract = {Risks from weather and climate extremes to governments, industries and communities are increasing and, at present, are not well quantified. In the presence of climate variability and long-term change, it may not be appropriate to base an assessment of the likelihood of climate hazards on the long-term averages. Many weather and climate extremes have increased in frequency and/or intensity in recent decades with climate model projections showing that several trends are likely to continue. The analysis of historical records is complementary to the use of climate models in understanding the changing nature of extremes. In this study, we apply a consistent methodology to examine the modulation in the probability of extremes in temperature and rainfall as they are influenced by climate change over the past century and natural climate variability and present summary tables and charts for a comprehensive comparison. The daily temperature data – maximum (Tmax) and minimum (Tmin) air temperature – are from a ‘high-quality' dataset developed at the Australian Bureau of Meteorology – the Australian Climate Observations Reference Network (ACORN) Surface Air Temperature (SAT) dataset. In the absence of a comparable dataset for daily rainfall, we analysed rainfall data at ACORN-SAT locations. Our analyses of extremes are based on annual maxima (annual minima for Tmin) of daily time series from 58 Australian sites over the period 1910–2009. We found statistically significant long-term increases in extreme maximum temperatures but with marked regional and seasonal variations. The increase in the lowest minimum temperature extremes typically exceeds the increase in the extremes of maximum temperature. Daily precipitation extremes rarely exhibit long-term change over the century but are strongly modulated by the El Ni{\~{n}}o Southern Oscillation (ENSO). The relative importance of long-term change and climate variability therefore depends on the variable or index. We conclude that in assessing the likelihood of climate hazards, one needs to consider the modulation of climate extremes due to both long-term change and climate variability.

This study uses a high-resolution coupled global climate model to simulate the changes in extreme winter conditions from the present climate to a future scenario with doubled CO 2 concentrations (2XC). In particular, this study focuses on changes in high-snowfall, extreme-wind (HSEW) events, which are defined as the occurrence of 2-day snowfall and high winds exceeding thresholds based on extreme values from the control simulation, where greenhouse gas concentrations remain fixed. Mean snowfall consistently decreases across the entire region, but extreme snowfall shows a more inconsistent pattern, with some areas experiencing increases in the frequency of extreme-snowfall events. Extreme-wind events show relatively small changes in frequency with 2XC, with the exception of high-elevation areas where there are large decreases in frequency. As a result of combined changes in wind and snowfall, HSEW events decrease in frequency in the 2XC simulation for much of eastern North America. Changes in the number of HSEW events in the 2XC environment are driven mainly by changes in the frequency of extreme-snowfall events, with most of the region experiencing decreases in event frequency, except for certain inland areas at higher latitudes.}, author = {Janoski, Tyler P. and Broccoli, Anthony J. and Kapnick, Sarah B. and Johnson, Nathaniel C.}, doi = {10.1175/JCLI-D-17-0756.1}, issn = {0894-8755}, journal = {Journal of Climate}, month = {nov}, number = {22}, pages = {9037--9054}, title = {{Effects of Climate Change on Wind-Driven Heavy-Snowfall Events over Eastern North America}}, url = {http://journals.ametsoc.org/doi/10.1175/JCLI-D-17-0756.1}, volume = {31}, year = {2018} } @article{Javed2017, abstract = {In this study, samples of dust naturally accumulated for various exposure times on photovoltaic (PV) panels were collected and characterized over a period of ten months in a solar test facility located in Doha, Qatar.

We characterize exposure at the global, regional, and grid-cell level; estimate the exposure that would be avoided by mitigating future levels of climate change (to RCP4.5); and quantify the dependence of exposure on population outcomes. We find that climate change is a stronger determinant of exposure than demographic change in these scenarios, with a global reduction in exposure of over 50{\%} under a lower emissions pathway, while a slower population growth pathway leads to roughly 30{\%} less exposure. Exposure reduction varies at the regional level, but in almost all cases, the RCP remains more influential than the SSP. Uncertainty in outcomes is dominated by inter-annual variability in heat extremes (relative to variability across initial condition ensemble members). For some regions, this variability is large enough that a reduction in annual exposure is not guaranteed in each individual year by following the lower forcing pathway.

Currently, industrialized animal production is a locally important source of excess nutrients. Various means have been employed to alleviate the negative consequences of eutrophication and cyanobacteria blooms, with controls on external nutrient inputs being the most effective.

The present study proposes a methodological framework for assessing the potential effects of climate change on landslide hazard at a national scale, under current (1961-2015) and future climate (2021-2050). The research approach for developing landslide hazard scenarios relies on the historical landslide inventory of the General Inspectorate for Emergency Situations (IGSU) (2005-2015), updated observational meteorological data and EURO-CORDEX projections of six GCM-RCM runs under two new IPCC scenarios (RCP4.5 and RCP8.5). Precipitation observation and projection data are analyzed in close relation to the landslide events reported within the historical landslide inventory, in order to develop national rainfall-induced landslide hazard scenarios. Maps displaying projected climate change impacts upon landslide hazard patterns and levels are constructed.

Specific approaches are required to address this gap between broad-scale model projections and regional, policy-relevant outcomes. Here, we apply a recently developed methodology that circumvents the GCM limitation of coarse resolution in order to project future changes in aridity on small islands.

The studied coastline has a length of 148 km and is oriented along the WNW-ESE direction.

For each variable, a relative risk value is assigned according to the potential magnitude of its contribution to physical changes on the coast as the sea-level rises. Every section of the coastline is assigned a risk ranking based on each variable, and the CSI is calculated as the square root of the product of the ranked variables divided by the total number of variables. Subsequently, a CSI map is produced for the studied coastline.

The rationale for this shift is said to be the demand for timely and actionable climate knowledge, whilst the means of its delivery involves a shift from public good to more privatised forms of climate science. This paper identifies important implications of this shift to climate services by examining the role of consultants, drawing on an in-depth study of adaptation consultants in Australia. The role of consultants is instructive, not just because these private sector experts are engaged in climate services, but also because publicly funded climate science agencies are increasingly encouraged to behave as consulting firms do. Four imperatives of knowledge businesses—to be client-focussed, solutions-oriented, resource-efficient and self-replicating—are described. The paper argues that an emphasis on climate services shifts the incentives for climate science away from the public interest towards the ongoing pursuit of profit. There is a subsequent diversion of effort away from publicly accessible and transparent climate information to private knowledge for discrete clients. Climate services also emphasise knowledge for climate solutions as opposed to the politically charged identification of climate risks. The paper concludes with a warning that the trend towards climate services undermines the knowledge required for societies to adequately respond to the scale, speed and severity of climate change.

No natural cause is apparent for these trends, whereas the observed drying and warming are consistent with model studies of the response to increases in greenhouse gases. Furthermore, model studies show an increasingly drier and hotter future mean climate for the Eastern Mediterranean. Analyses of observations and model simulations indicate that a drought of the severity and duration of the recent Syrian drought, which is implicated in the current conflict, has become more than twice as likely as a consequence of human interference in the climate system.}, author = {Kelley, Colin P. and Mohtadi, Shahrzad and Cane, Mark A. and Seager, Richard and Kushnir, Yochanan}, doi = {10.1073/pnas.1421533112}, isbn = {0027-8424}, issn = {0027-8424}, journal = {Proceedings of the National Academy of Sciences}, month = {mar}, number = {11}, pages = {3241--3246}, pmid = {25733898}, publisher = {National Academy of Sciences}, title = {{Climate change in the Fertile Crescent and implications of the recent Syrian drought}}, url = {http://www.pnas.org/lookup/doi/10.1073/pnas.1421533112}, volume = {112}, year = {2015} } @article{Kent2014a, annote = {doi: 10.1289/ehp.1307262}, author = {Kent, Shia T. and McClure, Leslie A. and Zaitchik, Benjamin F. and Smith, Tiffany T. and Gohlke, Julia M.}, doi = {10.1289/ehp.1307262}, issn = {0091-6765}, journal = {Environmental Health Perspectives}, month = {feb}, number = {2}, pages = {151--158}, publisher = {Environmental Health Perspectives}, title = {{Heat Waves and Health Outcomes in Alabama (USA): The Importance of Heat Wave Definition}}, url = {https://doi.org/10.1289/ehp.1307262 https://ehp.niehs.nih.gov/doi/10.1289/ehp.1307262}, volume = {122}, year = {2014} } @article{Kermanshah2017, abstract = {Climate change will impact urban infrastructure networks by changing precipitation patterns in a region. This study presents a novel vulnerability assessment framework for infrastructure networks against extreme rainfall-induced flash floods, with a specific application to transportation. The framework combines climate models, network science, geographical information systems (GIS), and stochastic modeling to compile a vulnerability surface (VS). Daily precipitation simulations for 2006–2100 from the Community Climate System Model, version 4 (CCSM4), are used to produce a stochastic simulation of extreme flash flood events in five U.S. cities—that is, Boston, Massachusetts; Houston, Texas; Miami, Florida; Oklahoma City, Oklahoma; and Philadelphia, Pennsylvania—under two different climate scenarios (RCP4.5 and RCP8.5). To assess the impact of these events, percentage drops in static (i.e., overall properties and robustness topological indicators) and dynamic (i.e., GIS accessibility and travel demand metrics) network properties are measured before and after simulated extreme events. The results of these metrics are inputs on a radar diagram to form a VS. Overall, the results show that changes in flash flood frequency due to climate change can have a significant impact on road networks, as was demonstrated recently in Houston, Texas. The magnitude of these impacts is chiefly associated with the geographic location of the cities and the size of the networks. The proposed framework can be reproduced in any city around the world, and researchers can use the results as guidelines for infrastructure design and planning purposes. Moreover, sensitivity analysis to varying greenhouse gas concentration trajectories can help local and national authorities to prioritize strategies for adaptation to climate change in more vulnerable regions.}, author = {Kermanshah, A and Derrible, S and Berkelhammer, M}, doi = {10.1175/JAMC-D-17-0083.1}, issn = {1558-8424}, journal = {Journal of Applied Meteorology and Climatology}, month = {sep}, number = {9}, pages = {2637--2650}, title = {{Using Climate Models to Estimate Urban Vulnerability to Flash Floods}}, url = {www.ametsoc.org/PUBSReuseLicenses https://journals.ametsoc.org/jamc/article/56/9/2637 /21722/Using-Climate-Models-to-Estimate-Urban}, volume = {56}, year = {2017} } @article{Kerr2018a, abstract = {The body of literature on ambient air pollution suggests that atmospheric stagnation events trigger high levels of air pollution.

The southern US is an exception to our overall findings as the strength of the relationship between the ASI and pollution is stronger and the percentage of co-occurring events is higher compared with other regions.

In eastern Africa droughts can cause crop failure and lead to food insecurity. With increasing temperatures, there is an a priori assumption that droughts are becoming more severe. However, the link between droughts and climate change is not sufficiently understood. Here we investigate trends in long-term agricultural drought and the influence of increasing temperatures and precipitation deficits. Using a combination of models and observational datasets, we studied trends, spanning the period from 1900 (to approximate pre-industrial conditions) to 2018, for six regions in eastern Africa in four drought-related annually averaged variables: soil moisture, precipitation, temperature, and evaporative demand (E0). In standardized soil moisture data, we found no discernible trends. The strongest influence on soil moisture variability was from precipitation, especially in the drier or water-limited study regions; temperature and E0 did not demonstrate strong relations to soil moisture. However, the error margins on precipitation trend estimates are large and no clear trend is evident, whereas significant positive trends were observed in local temperatures. The trends in E0 are predominantly positive, but we do not find strong relations between E0 and soil moisture trends. Nevertheless, the E0 trend results can still be of interest for irrigation purposes because it is E0 that determines the maximum evaporation rate. We conclude that until now the impact of increasing local temperatures on agricultural drought in eastern Africa is limited and we recommend that any soil moisture analysis be supplemented by an analysis of precipitation deficit.{\textless}/p{\textgreater}}, author = {Kew, Sarah F. and Philip, Sjoukje Y. and Hauser, Mathias and Hobbins, Mike and Wanders, Niko and van Oldenborgh, Geert Jan and van der Wiel, Karin and Veldkamp, Ted I.

Five island-wide and multidecadal averages of daily precipitation and temperature were estimated by way of a climatology-informed interpolation of the site-specific downscaled climate model output. Annual cooling degree-days (CDD) were calculated as a proxy index for air-conditioning energy demand, and two measures of annual no-rainfall days were used as drought indices. Holdridge life zone classification was used to map the possible ecological effects of climate change. Precipitation is predicted to decline in both model ensembles, but the decrease was more severe in the "regionally consistent" models. The precipitation declines cause gradual and linear increases in drought intensity and extremes. The warming from the 1960-90 period to the 2071-99 period was 4.6°-9°C depending on the global emission scenarios and location. This warming may cause increases in CDD, and consequently increasing energy demands.

We investigate European regional climate change for time periods when the global mean temperature has increased by 1.5 and 2°C compared to pre-industrial conditions. Results are based on regional downscaling of transient climate change simulations for the 21st century with global climate models (GCMs) from the fifth-phase Coupled Model Intercomparison Project (CMIP5). We use an ensemble of EURO-CORDEX high-resolution regional climate model (RCM) simulations undertaken at a computational grid of 12.5km horizontal resolution covering Europe. The ensemble consists of a range of RCMs that have been used for downscaling different GCMs under the RCP8.5 forcing scenario. The results indicate considerable near-surface warming already at the lower 1.5°C of warming. Regional warming exceeds that of the global mean in most parts of Europe, being the strongest in the northernmost parts of Europe in winter and in the southernmost parts of Europe together with parts of Scandinavia in summer. Changes in precipitation, which are less robust than the ones in temperature, include increases in the north and decreases in the south with a borderline that migrates from a northerly position in summer to a southerly one in winter. Some of these changes are already seen at 1.5°C of warming but are larger and more robust at 2°C. Changes in near-surface wind speed are associated with a large spread among individual ensemble members at both warming levels. Relatively large areas over the North Atlantic and some parts of the continent show decreasing wind speed while some ocean areas in the far north show increasing wind speed. The changes in temperature, precipitation and wind speed are shown to be modified by changes in mean sea level pressure, indicating a strong relationship with the large-scale circulation and its internal variability on decade-long timescales. By comparing to a larger ensemble of CMIP5 GCMs we find that the RCMs can alter the results, leading either to attenuation or amplification of the climate change signal in the underlying GCMs. We find that the RCMs tend to produce less warming and more precipitation (or less drying) in many areas in both winter and summer.}, author = {Kjellstr{\"{o}}m, Erik and Nikulin, Grigory and Strandberg, Gustav and Christensen, Ole B{\o}ssing and Jacob, Daniela and Keuler, Klaus and Lenderink, Geert and van Meijgaard, Erik and Sch{\"{a}}r, Christoph and Somot, Samuel and S{\o}rland, Silje Lund and Teichmann, Claas and Vautard, Robert}, doi = {10.5194/esd-9-459-2018}, issn = {2190-4987}, journal = {Earth System Dynamics}, month = {may}, number = {2}, pages = {459--478}, title = {{European climate change at global mean temperature increases of 1.5 and 2 °C above pre-industrial conditions as simulated by the EURO-CORDEX regional climate models}}, url = {https://www.earth-syst-dynam.net/9/459/2018/}, volume = {9}, year = {2018} } @article{Kjellstrom2016a, abstract = {We describe the process of building a climate service centred on regional climate model results from the Rossby Centre regional climate model RCA4.

Author opinion was more mixed and confidence levels lower for the following projections: 5) a further poleward expansion of the latitude of maximum TC intensity in the western North Pacific; 6) a decrease of global TC frequency, as projected in most studies; 7) an increase in global very intense TC frequency (category 4–5), seen most prominently in higher-resolution models; and 8) a slowdown in TC translation speed.}, author = {Knutson, Thomas R. and Camargo, Suzana J and Chan, Johnny C L and Emanuel, Kerry and Ho, Chang-Hoi and Kossin, James and Mohapatra, Mrutyunjay and Satoh, Masaki and Sugi, Masato and Walsh, Kevin and Wu, Liguang}, doi = {10.1175/BAMS-D-18-0194.1}, issn = {0003-0007}, journal = {Bulletin of the American Meteorological Society}, month = {mar}, number = {3}, pages = {E303--E322}, title = {{Tropical Cyclones and Climate Change Assessment: Part II: Projected Response to Anthropogenic Warming}}, url = {https://doi.org/10.1175/BAMS-D-18-0194.1}, volume = {101}, year = {2020} } @article{Knutson2018c, author = {Knutson, Thomas R. and Zeng, Fanrong}, doi = {10.1175/JCLI-D-17-0672.1}, issn = {08948755}, journal = {Journal of Climate}, keywords = {Anthropogenic effects,Atmosphere,Climate change,Climate models,Precipitation}, month = {jun}, number = {12}, pages = {4617--4637}, title = {{Model assessment of observed precipitation trends over land regions: Detectable human influences and possible low bias in model trends}}, url = {http://journals.ametsoc.org/doi/10.1175/JCLI-D-17-0672.1}, volume = {31}, year = {2018} } @article{Knutson2019, abstract = {An assessment was made of whether detectable changes in tropical cyclone (TC) activity are identifiable in observations and whether any changes can be attributed to anthropogenic climate change.

A number of specific published conclusions (case studies) about possible detectable anthropogenic influence on TCs were assessed using the conventional approach of preferentially avoiding type I errors (i.e., overstating anthropogenic influence or detection). We conclude there is at least low to medium confidence that the observed poleward migration of the latitude of maximum intensity in the western North Pacific is detectable, or highly unusual compared to expected natural variability. Opinion on the author team was divided on whether any observed TC changes demonstrate discernible anthropogenic influence, or whether any other observed changes represent detectable changes. The issue was then reframed by assessing evidence for detectable anthropogenic influence while seeking to reduce the chance of type II errors (i.e., missing or understating anthropogenic influence or detection). For this purpose, we used a much weaker “balance of evidence” criterion for assessment. This leads to a number of more speculative TC detection and/or attribution statements, which we recognize have substantial potential for being false alarms (i.e., overstating anthropogenic influence or detection) but which may be useful for risk assessment.

These "mega slumps" (5-40ha) are now common in formerly glaciated, fluvially incised, ice-cored terrain of the Peel Plateau, NW Canada. Individual thaw slumps can persist for decades and their enlargement due to ground ice thaw can displace up to 106m3 of materials from slopes to valley bottoms reconfiguring slope morphology and drainage networks. Analysis of Landsat images (1985-2011) indicate that the number and size of active slumps and debris tongue deposits has increased significantly with the recent intensification of rainfall. The analyses of high resolution climatic and photographic time-series for summers 2010 and 2012 shows strong linkages amongst temperature, precipitation and the downslope sediment flux from active slumps. Ground ice thaw supplies meltwater and sediments to the slump scar zone and drives diurnal pulses of surficial flow. Coherence in the timing of down valley debris tongue deposition and fine-scaled observations of sediment flux indicate that heavy rainfall stimulates major mass flow events. Evacuation of sediments from the slump scar zone can help to maintain a headwall of exposed ground ice, perpetuating slump growth and leading to larger disturbances. The development of debris tongue deposits divert streams and increase thermoerosion to initiate adjacent slumps.

We generated weather based on historical and projected future climate in South-eastern and Central Norway. Using this weather data as input, we simulated spring workability, attainable yield, timeliness costs, and mechanization management with a workability model and a mechanization model. The projected climate changes resulted in improved workability for spring fieldwork and higher attainable yield in South-eastern Norway, and either positive or negative changes in Central Norway compared to historical conditions. We observed a general increase in variability of workability and attainable yield, and a larger risk of extremely unfavourable years in the most unfavourable scenarios in Central Norway. Changes in profitability and mechanization management were small, but followed the same pattern. The negative effects in the most unfavourable climate scenarios in Central Norway were in contrast to positive effects in earlier studies. We explained discrepancies by differences in research methods and purpose. However, simulated sowing dates of annual crops should consider workability of the soil, in terms of water content. Under worst-case conditions, in need of a certain time window to complete their spring fieldwork, farmers might adapt to impaired spring workability by working the soil at higher water content than simulated in our study. The consequence would be a larger loss of attainable yield and less profitability in the future.

Sea level rise models for nine coastal sites in the United States, a review of US Nuclear Regulatory Commission documents, and reports from France's nuclear regulatory agency provided insights into issues that have arisen from sea level rise, shoreline erosion, coastal storms, floods, and heat waves. Applying the criteria to inland and coastal nuclear power plants reveals several weaknesses. Safety stands out as the primary concern at coastal locations, while inland locations encounter greater problems with interrupted operation. Adapting nuclear power to climate change entails either increased expenses for construction and operation or incurs significant costs to the environment and public health and welfare.

Another key factor that governs the genesis and intensity of hurricanes is ambient environmental vertical wind shear8,9,10 (VWS). Warmer SSTs generally correlate with more frequent genesis and greater potential intensity, while VWS inhibits genesis and prevents any hurricanes that do form from reaching their potential intensity. When averaged over the main hurricane-development region in the Atlantic, SST and VWS co-vary inversely11,12, so that the two factors act in concert to either enhance or inhibit basin-wide hurricane activity. Here I show, however, that conditions conducive to greater basin-wide Atlantic hurricane activity occur together with conditions for more probable weakening of hurricanes near the United States coast. Thus, the VWS and SST form a protective barrier along the United States coast during periods of heightened basin-wide hurricane activity. Conversely, during the most-recent period of basin-wide quiescence, hurricanes (and particularly major hurricanes) near the United States coast, although substantially less frequent, exhibited much greater variability in their rate of intensification, and were much more likely to intensify rapidly.

Here, we perform the most comprehensive meta-analysis to date by synthesizing the results of 228 studies examining biological responses to ocean acidification. The results reveal decreased survival, calcification, growth, development and abundance in response to acidification when the broad range of marine organisms is pooled together. However, the magnitude of these responses varies among taxonomic groups, suggesting there is some predictable trait-based variation in sensitivity, despite the investigation of approximately 100 new species in recent research. The results also reveal an enhanced sensitivity of mollusk larvae, but suggest that an enhanced sensitivity of early life history stages is not universal across all taxonomic groups. In addition, the variability in species' responses is enhanced when they are exposed to acidification in multi-species assemblages, suggesting that it is important to consider indirect effects and exercise caution when forecasting abundance patterns from single-species laboratory experiments.

Considerable debates remain regarding the impacts of climate change on wind extremes. While climate models have occasionally shown increases in regional wind extremes, a decline in the magnitude of mean and extreme near-surface wind speeds has been recently reported over most regions of the Northern Hemisphere using observed data. Previous studies of wind extremes under climate change have focused on selected regions and employed outputs from the regional climate models (RCMs). However, RCMs ultimately rely on the outputs of global circulation models (GCMs), and the value-addition from the former over the latter has been questioned. Regional model runs rarely employ the full suite of GCM ensembles, and hence may not be able to encapsulate the most likely projections or their variability. Here we evaluate the performance of the latest generation of GCMs, the Coupled Model Intercomparison Project phase 5 (CMIP5), in simulating extreme winds. We find that the multimodel ensemble (MME) mean captures the spatial variability of annual maximum wind speeds over most regions except over the mountainous terrains. However, the historical temporal trends in annual maximum wind speeds for the reanalysis data, ERA-Interim, are not well represented in the GCMs. The historical trends in extreme winds from GCMs are statistically not significant over most regions. The MME model simulates the spatial patterns of extreme winds for 25–100 year return periods. The projected extreme winds from GCMs exhibit statistically less significant trends compared to the historical reference period.}, author = {Kumar, Devashish and Mishra, Vimal and Ganguly, Auroop R}, doi = {10.1007/s00382-014-2306-2}, issn = {1432-0894}, journal = {Climate Dynamics}, number = {1}, pages = {441--453}, title = {{Evaluating wind extremes in CMIP5 climate models}}, url = {https://doi.org/10.1007/s00382-014-2306-2}, volume = {45}, year = {2015} } @article{Kundzewicz2014, abstract = {A holistic perspective on changing rainfall-driven flood risk is provided for the late 20th and early 21st centuries.

The increment in greenhouse gas emissions and its effect on climate is such that the need for the agricultural sector to adapt seems inevitable. However, given that adaptive measures are limited, it is possible that climate change will affect food availability and increase price volatility. This essay presents a synthesis of the evidence of the effects that climate change has on the agricultural sector, with a special emphasis on Latin America. This revision makes it clear that the effects are going to be heterogeneous and that they could very well be costly. Therefore, public policies aimed at reducing greenhouse gas emissions while at the same time promoting adaptive measures to climate change, are essential. The essay concludes with some considerations on future research topics that could contribute to the design of said public policies.

These models were integrated in the framework of the CLARIS-LPB 7FP-EU-project. We analyze the capability of RCMs to reproduce such indices and explore changes projected by the models under the scenario A1B for the end of the 21st century. The work also analyzes the role of cloudiness, surface radiative forcing and meridional wind components on temperature extremes. Future projections show that, during the austral summer, the increase in the frequency of warm nights is larger than that projected for warm days. This result agrees with the projections for the seasonal mean fields of minimum temperature (TN) versus the maximum temperature (TX) over most of SA. The analysis for the La Plata Basin suggests that this behavior is consistent with the cooling effect of cloud cover affecting TX, while TN is affected by nighttime greenhouse warming. The relationship between cloudiness and TN and TX anomalies shows a nonlinear behavior for near full cloud cover conditions. Although TX and TN anomalies are sensitive to strong cold air advection, TX is more sensitive than TN. Thus, RCMs are useful tools to analyze both the spatial pattern of temperature extremes and the climatic factors involved.}, author = {L{\'{o}}pez-Franca, Noelia and Zaninelli, PG and Carril, AF and Men{\'{e}}ndez, CG and S{\'{a}}nchez, Enrique}, doi = {10.3354/cr01393}, issn = {0936-577X}, journal = {Climate Research}, keywords = {Climate change,Multi-model ensemble,Regional climate models,South America,Temperature extremes}, month = {may}, number = {2-3}, pages = {151--167}, title = {{Changes in temperature extremes for 21st century scenarios over South America derived from a multi-model ensemble of regional climate models}}, url = {http://www.int-res.com/abstracts/cr/v68/n2-3/p151-167/}, volume = {68}, year = {2016} } @article{Lopez-Moreno2009, abstract = {In this study, snowpack series are modeled across the Pyrenees using data derived from the HIRHAM Regional Climate Model for both the control period (1960-1990) and two emission scenarios (SRES B2 and A2) by the end of the 21st century (2070-2100). A comparison of future and control simulations enables us to quantify the expected change in snowpack for the next century. Snow simulations are performed on 20 Regional Climate Model (RCM) grid points over the Pyrenees, covering the entire north-south and east-west transects; data were downscaled for four different altitudinal levels (1500, 2000, 2500, and 3000 m a.s.l.). This procedure yields a relatively complete picture of the expected impacts of climate change in the Pyrenees, covering horizontal spatial variability as well as altitudinal gradients. According to the HIRHAM model projections following different greenhouse gas emission scenarios, the thickness and duration of snowpack in the Pyrenees will decrease dramatically over the next century, especially in the central and eastern sectors of the Spanish Pyrenees. The magnitude of these impacts will follow a marked altitudinal gradient: the maximum accumulated snow water equivalent may decrease by up to 78{\%}, and the season with snow cover may be reduced by up to 70{\%} at 1500 m a.s.l. The magnitude of the impacts decreases rapidly with increasing altitude; snowpack characteristics will remain largely similar in the highest sectors. The decline of the snowpack would be reduced by half if a medium-low emission scenario was considered (B2) instead of the medium-high concentrations of greenhouse gas assumed in the A2 scenario. {\textcopyright} 2009 Elsevier B.V.

This is the first such analysis for the entire mountain range using SAFRAN-Crocus simulations run for this specific purpose. The SAFRAN-Crocus simulations were evaluated for the period 1980–2016 using 28 in situ snow depth data time series, and for the period 2000–2017 using MODIS observations of the snow cover duration. Following confirmation that the simulated snow series satisfactorily reproduced the observed evolution of the snowpack, the Mann–Kendall test showed that snow cover duration and average depth decreased during the full study period, but this was only statistically significant at 2,100 m a.s.l. The temporal evolution in the snow series indicated marked differences among massifs, elevations, and snow variables. In general, the most western massifs of the French Pyrenees underwent a greater decrease in the snowpack, while in some eastern massifs the snowpack did not decrease, and in some cases increased at 1,500 m a.s.l. The results suggest that the trends were consistent over time, as they were little affected by the start and end year of the study period, except if trends are computed only starting after 1980, when no significant trends were apparent. Most of the observed negative trends were not correlated with changes in the atmospheric circulation patterns during the snow season. This suggests that the continuous warming in the Pyrenees since the beginning of the industrial period, and particularly the sharp increase since 1955, is a major driver explaining the snow cover decline in the Pyrenees.}, author = {L{\'{o}}pez-Moreno, J.

Meteorological observations from high elevations were used to simulate the snow energy and mass balance (SEMB) and calculate its sensitivity to climate. Very different climate sensitivities were evident amongst the various sites. For example, reductions of 9{\%}-19{\%} and 6-28 days in the mean snow water equivalent (SWE) and snow duration, respectively, were found per °C increase. Simulated changes in precipitation (±20{\%}) did not affect the sensitivities. The Andes and Atlas Mountains have a shallow and cold snowpack, and net radiation dominates the SEMB; and explains their relatively low sensitivity to climate warming. The Pyrenees and USA Sierra Nevada have a deeper and warmer snowpack, and sensible heat flux is more important in the SEMB; this explains the much greater sensitivities of these regions. Differences in sensitivity help explain why, in regions where climate models project relatively greater temperature increases and drier conditions by 2050 (such as the Spanish Sierra Nevada and the Moroccan Atlas Mountains), the decline in snow accumulation and duration is similar to other sites (such as the Pyrenees and the USA Sierra Nevada), where models project stable precipitation and more attenuated warming.

To our knowledge, this is the first study to quantify the consequences of climate change upon pollen allergy in humans. Objectives: We produced quantitative estimates of the potential impact of climate change upon pollen allergy in humans, focusing upon common ragweed (Ambrosia artemisiifolia) in Europe. Methods: A process-based model estimated the change in ragweed's range under climate change. A second model simulated current and future ragweed pollen levels. These findings were translated into health burdens using a dose-response curve generated from a systematic review and from current and future population data. Models considered two different suites of regional climate/pollen models, two greenhouse gas emissions scenarios {\{}[{\}}Representative Concentration Pathways (RCPs) 4.5 and 8.5], and three different plant invasion scenarios. Results: Our primary estimates indicated that sensitization to ragweed will more than double in Europe, from 33 to 77 million people, by 2041-2060. According to our projections, sensitization will increase in countries with an existing ragweed problem (e.g., Hungary, the Balkans), but the greatest proportional increases will occur where sensitization is uncommon (e.g., Germany, Poland, France). Higher pollen concentrations and a longer pollen season may also increase the severity of symptoms. Our model projections were driven predominantly by changes in climate (66{\%}) but were also influenced by current trends in the spread of this invasive plant species. Assumptions about the rate at which ragweed spreads throughout Europe had a large influence upon the results. Conclusions: Our quantitative estimates indicate that ragweed pollen allergy will become a common health problem across Europe, expanding into areas where it is currently uncommon.

Here, we show that diurnal temperature range (DTR) affects two important parameters underlying dengue virus (DENV) transmission by Aedes aegypti. In two independent experiments using different DENV serotypes, mosquitoes were less susceptible to virus infection and died faster under larger DTR around the same mean temperature. Large DTR (20 °C) decreased the probability of midgut infection, but not duration of the virus extrinsic incubation period (EIP), compared with moderate DTR (10 °C) or constant temperature. A thermodynamic model predicted that at mean temperatures {\&}lt;18 °C, DENV transmission increases as DTR increases, whereas at mean temperatures {\&}gt;18 °C, larger DTR reduces DENV transmission. The negative impact of DTR on Ae. aegypti survival indicates that large temperature fluctuations will reduce the probability of vector survival through EIP and expectation of infectious life. Seasonal variation in the amplitude of daily temperature fluctuations helps to explain seasonal forcing of DENV transmission at locations where average temperature does not vary seasonally and mosquito abundance is not associated with dengue incidence. Mosquitoes lived longer and were more likely to become infected under moderate temperature fluctuations, which is typical of the high DENV transmission season than under large temperature fluctuations, which is typical of the low DENV transmission season.

The aim of this paper is to map the global landscape of research on climate services and to identify patterns at individual, affiliation and country level and the structural properties of each community. We use a sample of 358 records published between 1974 and 2018 and quantitatively analyze them. We provide insights into the main characteristics of the community of climate services through Bibliometrics and complement these findings with Network Science. We have computed the centrality of each actor as derived from a Principal Component Analysis of 42 different measures. By exploring the structural properties of the networks of individuals, institutions and countries we derive implications on the most central agents. Furthermore, we detect brokers in the network, capable of facilitating the information flow and increasing the cohesion of the community. We finally analyze the abstracts of the sample via Content Analysis. We find a progressive shift towards climate adaptation and user-centric visions. Agriculture and Energy are the top mentioned sectors. Anglophone countries and institutions are quantitatively dominant, and they are also important in connecting different discipline of the network of scholars, by building on established partnerships.

Additionally, temporal time series are examined in three locations: the central North Atlantic, Finland and Iberian Peninsula. The 40-year mean and the 98th percentile wind speeds emphasize a distinct land-sea contrast and a seasonal variation with the strongest winds over the ocean and during winter. The strongest winds and the highest variability are associated with the storm tracks and local wind phenomena such as the mistral. The extremeness of the winds is examined with an extreme wind factor (the 98th percentile divided by mean wind speeds) which in all months is higher in southern Europe than in northern Europe. Mostly no linear trends in 10-m wind speeds are identified in the three locations but large annual and decadal variability is evident. The decadal 10-m wind speeds were stronger than average in the 1990s in northern Europe and in the 1980s and 2010s in southern Europe. These decadal changes were largely explained by the positioning of the jet stream and storm tracks and the strength of the north?south pressure gradient in the North Atlantic. The 10-m winds have a positive correlation with the North Atlantic Oscillation in the central North Atlantic and Finland on annual scales and during cold season months and a negative correlation in Iberian Peninsula mostly from July to March. The Atlantic Multi-decadal Oscillation has a moderate negative correlation with the winds in the central North Atlantic but no correlation in Finland and Iberian Peninsula.

In these environments, sea-level rise will exacerbate coastal erosion to an amount which remains uncertain. Sandy shoreline change projections inherit the uncertainties of future mean sea-level changes, of vertical ground motions, and of other natural and anthropogenic processes affecting shoreline change variability and trends. Furthermore, the erosive impact of sea-level rise itself can be quantified using two fundamentally different models. Here, we show that this latter source of uncertainty, which has been little quantified so far, can account for 20 to 40{\%} of the variance of shoreline projections by 2100 and beyond. This is demonstrated for four contrasting sandy beaches that are relatively unaffected by human interventions in southwestern France, where a variance-based global sensitivity analysis of shoreline projection uncertainties can be performed owing to previous observations of beach profile and shoreline changes. This means that sustained coastal observations and efforts to develop sea-level rise impact models are needed to understand and eventually reduce uncertainties of shoreline change projections, in order to ultimately support coastal land-use planning and adaptation. Since 1870, sea level has been rising, mainly due to the melting of land-ice and ocean expansion caused by anthro-pogenic climate warming 1-5. While the most immediate impact of sea-level rise is increased coastal flooding hazards 6-13 , there are significant concerns regarding shoreline retreat as well 6,14-26. In particular, beaches backed by sandy deposits are receiving particular attention for several reasons: first, they represent 31{\%} of the world's ice-free coasts 25 ; second, they are potentially highly sensitive to sea-level changes 14-16,24 ; third, it has been estimated that at least 24{\%} and up to 70{\%} of the world beaches are already under chronic erosion, although with large regional and local differences 25,27 ; finally, beaches are both valuable for tourism and as buffer zones during extreme events such as storms. Sandy shoreline change projections along a given coast need to consider sediment losses and gains caused by a number of hydro-sedimentary processes acting at different timescales 28. Coastal change is driven by a myr-iad of processes interacting with one another at a wide range of spatial and temporal scales, making the use of process-based coastal evolution modelling difficult at operational levels. Hence, instead of attempting to quantify the impact of each process causing sediment transport, coastal adaptation practitioners have pragmatically relied on extrapolations of past observations in order to anticipate future shoreline changes. In the absence of human interventions, estuaries or other major sediment sources or sinks, this results in the following equation: ∆ = +. + + L L n Tx Lvar S (1) r r slr 0 where L r0 and L r are the shoreline positions in a cross-shore direction at the initialization and after n years, respectively, Tx is the linear trend over multi-decadal to centennial timescales, and Lvar represents the seasonal, inter-annual and decadal modes of variability of shoreline changes.

In this paper, we review previous studies that explored the relations between sea-level rise and shoreline changes over the last few decades. Existing methods can be classified into two groups: (1) approaches based on the analysis of trends and variability in shoreline change observations, which investigate whether a correlation with the temporal or spatial patterns sea level changes can be established; and (2) approaches based on the comparison of shoreline observations with a coastal model outcome, which attempt to evaluate the contribution of sea-level rise to shoreline mobility using coastal evolution modeling tools. The existing applications of these methods face two common difficulties: first, shoreline data are often lacking or insufficiently resolved temporally to capture the dynamics of coastlines; and second, relative sea level along the coast is generally only known in a limited number of areas where tide gauges are available. These two challenges can be met, owing to the increasing amount of shoreline change observations and complementary geodetic techniques.

The sustainability of this trend has been questioned, and future environmental changes, such as climate change, may cause some regions to become less suitable for livestock. Livestock and wild herbivores are strongly dependent on the nutritional chemistry of forage plants. Nutrition is positively linked to weight gains, milk production and reproductive success, and nutrition is also a key determinant of enteric methane production. In this meta-analysis, we assessed the effects of growing conditions on forage quality by compiling published measurements of grass nutritive value and combining these data with climatic, edaphic and management information. We found that forage nutritive value was reduced at higher temperatures and increased by nitrogen fertiliser addition, likely driven by a combination of changes to species identity and changes to physiology and phenology. These relationships were combined with multiple published empirical models to estimate forage- and temperature-driven changes to cattle enteric methane production.

These estimates require refinement and a greater knowledge of the abundance, size, feeding regime and location of cattle, and the representation of heat stress should be included in future modelling work.

Instead of providing a deterministic estimate, this study investigates the likelihood of yield loss of wheat, maize, rice and soybeans in response to droughts of various intensities in the 10 largest producing countries. We use crop-country specific standardized precipitation index (SPI) and census yield data for 1961–2016 to build a probabilistic modeling framework for estimating yield loss risk under a moderate (−1.2 {\textless} SPI {\textless} −0.8), severe (−1.5 {\textless} SPI {\textless} −1.3), extreme (−1.9 {\textless} SPI {\textless} −1.6) and exceptional (SPI {\textless} −2.0) drought. Results show that there is {\textgreater}80{\%} probability that wheat production will fall below its long-term average when experiencing an exceptional drought, especially in USA and Canada. As for maize, India shows the highest risk of yield reduction under droughts, while rice is the crop that is most vulnerable to droughts in Vietnam and Thailand. Risk of drought-driven soybean yield loss is the highest in USA, Russian and India. Yield loss risk tends to grow faster when experiencing a shift in drought severity from moderate to severe than that from extreme to the exceptional category, demonstrating the non-linear response of yield to the increase in drought severity. Sensitivity analysis shows that temperature plays an important role in determining drought impacts, through reducing or amplifying drought-driven yield loss risk. Compared to present conditions, an ensemble of 11 crop models simulated an increase in yield loss risk by 9{\%}–12{\%}, 5.6{\%}–6.3{\%}, 18.1{\%}–19.4{\%} and 15.1{\%}–16.1 for wheat, maize, rice and soybeans by the end of 21st century, respectively, without considering the benefits of CO 2 fertilization and adaptations.

The Australian air quality standard of 50$\mu$g/m3per 24h was massively exceeded at Randwick (1734$\mu$g/m3) and Newcastle (2426$\mu$g/m3).

Predicting rice (Oryza sativa) productivity under future climates is important for global food security. Ecophysiological crop models in combination with climate model outputs are commonly used in yield prediction, but uncertainties associated with crop models remain largely unquantified. We evaluated 13 rice models against multi-year experimental yield data at four sites with diverse climatic conditions in Asia and examined whether different modeling approaches on major physiological processes attribute to the uncertainties of prediction to field measured yields and to the uncertainties of sensitivity to changes in temperature and CO2concentration [CO2]. We also examined whether a use of an ensemble of crop models can reduce the uncertainties. Individual models did not consistently reproduce both experimental and regional yields well, and uncertainty was larger at the warmest and coolest sites. The variation in yield projections was larger among crop models than variation resulting from 16 global climate model-based scenarios. However, the mean of predictions of all crop models reproduced experimental data, with an uncertainty of less than 10{\%} of measured yields. Using an ensemble of eight models calibrated only for phenology or five models calibrated in detail resulted in the uncertainty equivalent to that of the measured yield in well-controlled agronomic field experiments.

To ascertain the spatial and temporal distribution characteristics of high-altitude river ice at the basin scale, we selected the Babao River basin as the study area, which is a typical river basin located in the northeastern Tibetan Plateau.

We also found that gentle slopes and high elevations are beneficial for the development of river ice. The melting of river ice supplements river discharge in spring.

This study investigates the global response of the midlatitude atmospheric circulation to 1.5 and 2.0 °C of warming using the HAPPI (Half a degree Additional warming, Prognosis and Projected Impacts) ensemble, with a focus on the winter season. Characterising and understanding this response is critical for accurately assessing the near-term regional impacts of climate change and the benefits of limiting warming to 1.5 °C above pre-industrial levels, as advocated by the Paris Agreement of the United Nations Framework Convention on Climate Change (UNFCCC). The HAPPI experimental design allows an assessment of uncertainty in the circulation response due to model dependence and internal variability. Internal variability is found to dominate the multi-model mean response of the jet streams, storm tracks, and stationary waves across most of the midlatitudes; larger signals in these features are mostly consistent with those seen in more strongly forced warming scenarios. Signals that emerge in the 1.5 °C experiment are a weakening of storm activity over North America, an inland shift of the North American stationary ridge, an equatorward shift of the North Pacific jet exit, and an equatorward intensification of the South Pacific jet. Signals that emerge under an additional 0.5 °C of warming include a poleward shift of the North Atlantic jet exit, an eastward extension of the North Atlantic storm track, and an intensification on the flanks of the Southern Hemisphere storm track. Case studies explore the implications of these circulation responses for precipitation impacts in the Mediterranean, in western Europe, and on the North American west coast, paying particular attention to possible outcomes at the tails of the response distributions. For example, the projected weakening of the Mediterranean storm track emerges in the 2 °C warmer world, with exceptionally dry decades becoming 5 times more likely.}, archivePrefix = {arXiv}, arxivId = {quant-ph/1206.5131}, author = {Li, Camille and Michel, Clio and {Seland Graff}, Lise and Bethke, Ingo and Zappa, Giuseppe and Bracegirdle, Thomas J. and Fischer, Erich and Harvey, Ben J. and Iversen, Trond and King, Martin P. and Krishnan, Harinarayan and Lierhammer, Ludwig and Mitchell, Daniel and Scinocca, John and Shiogama, Hideo and Stone, D{\'{a}}ith{\'{i}} A. and Wettstein, Justin J.}, doi = {10.5194/esd-9-359-2018}, eprint = {1206.5131}, isbn = {9781509015764}, issn = {2190-4987}, journal = {Earth System Dynamics}, month = {apr}, number = {2}, pages = {359--382}, primaryClass = {quant-ph}, title = {{Midlatitude atmospheric circulation responses under 1.5 and 2.0 °C warming and implications for regional impacts}}, url = {https://www.earth-syst-dynam.net/9/359/2018/ https://esd.copernicus.org/articles/9/359/2018/}, volume = {9}, year = {2018} } @article{LI201453, abstract = {Knowledge about future oceanographic events will assist governments to better manage risk in coastal zones, a crucial task in the light of projected sea level rise, population growth and economic development.

The aridity index (AI), defined as the ratio of annual precipitation (Pre) to atmospheric evaporation (potential evapotranspiration [PET]), represents an efficient indicator of climatic changes. However, the variations and underlying drivers of AI values have not been comprehensively compared in different climatic regions. Using the AI calculated on the basis of bias-corrected precipitation and optimized PET over the period of 1999?2017 and two climate model projections for the coming century, we investigated the response of the AI to climate change and quantified the contributions of climatic factors to AI variations in eight climatic regions in China, that is, the northwest (NW), north-centre (NC), northeast (NE), North China Plain (NCP), east (E), southeast (SE), southwest (SW) and Tibet Plateau (TP). The results indicated that the AI values in seven of the eight climate regions exhibited negative trends from 1999 to 2017, with mean values ranging from ?0.0008 in SW to ?0.0414 in NC, while the AI values in the TP region showed a significant positive trend, with a value of 0.0124. Pre was the dominant factor for the variations in AI values in all climate regions, with contribution rates from 65 to 308{\%}, followed by decreasing solar radiation in the NW, NC, E, SE and SW regions; deceasing wind speed in NE and NCP; and deceasing actual vapour pressure in the TP. The effect of increasing temperature on the AI trend was offset by other climate factors. By the end of the 21st century, under the Representative Concentration Pathway 8.5 emission scenario, the AI will significantly increase in five of the eight regions to values approximately 16.5{\%} higher than those during 1999?2017, and this increase in the AI will be dominated by increasing PET. Overall, the shift in the dominant AI factor from Pre in recent years to PET in the future indicates that more attention should be given to the response of the AI to global warming. Furthermore, regional differences in climate change and AI values during 2018?2,100 will inevitably influence water availability and urgently require the development of adaptation strategies for different climatic regions.}, annote = {https://doi.org/10.1002/joc.6137}, author = {Li, Yanzhong and Yu, Wenjun and Wang, Kaiwen and Ma, Xieyao}, doi = {10.1002/joc.6137}, file = {::}, issn = {0899-8418}, journal = {International Journal of Climatology}, keywords = {aridity index,attribution,climatic regions,global climate models (GCMs)}, month = {nov}, number = {14}, pages = {5256--5272}, publisher = {John Wiley {\&} Sons, Ltd}, title = {{Comparison of the aridity index and its drivers in eight climatic regions in China in recent years and in future projections}}, url = {https://doi.org/10.1002/joc.6137 https://onlinelibrary.wiley.com/doi/abs/10.1002/joc.6137}, volume = {39}, year = {2019} } @article{Li2016f, author = {Li, Zhiying and Fang, Haiyan}, doi = {10.1016/j.earscirev.2016.10.004}, issn = {00128252}, journal = {Earth-Science Reviews}, month = {dec}, pages = {94--117}, title = {{Impacts of climate change on water erosion: A review}}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0012825216303555}, volume = {163}, year = {2016} } @article{doi:10.1175/JCLI-D-15-0500.1, abstract = { AbstractBased on a comprehensive collection of hail observations and the NCEP–NCAR reanalyses from 1960 to 2012, the long-term trends of hail day frequency in mainland China and the associated changes in atmospheric circulation patterns were analyzed. There was no detectable trend in hail frequency from 1960 to the early 1980s, but a significant decreasing trend was apparent in later periods throughout most of China and in particular over the Tibetan Plateau from the early 1980s and over northern and northwestern China from the early 1990s. Hail frequency in southern China did not decrease as significantly as in other regions over the last couple of decades. An objective classification method, the obliquely rotated T-mode principal component technique, was used to investigate atmospheric circulation patterns. It was found that 51.85{\%} of the hail days occurred during two major circulation types, both of which were associated with cold frontal systems in northern China. More specifically, the synoptic trough in East Asia, signified by the meridional circulation at 850 hPa, became considerably weaker after 1990. This change in the synoptic pattern is consistent with a weakening trend in the East Asian summer monsoon, the primary dynamic forcing of moisture transport that contributes to the generation of severe convection in northern China. The long-term variability of hail day frequency over the Tibetan Plateau was more strongly correlated with the change in mean freezing-level height (FLH) than the strength of the East Asian monsoon. }, author = {Li, Mingxin and Zhang, Qinghong and Zhang, Fuqing}, doi = {10.1175/JCLI-D-15-0500.1}, journal = {Journal of Climate}, number = {19}, pages = {7027--7044}, title = {{Hail Day Frequency Trends and Associated Atmospheric Circulation Patterns over China during 1960–2012}}, url = {https://doi.org/10.1175/JCLI-D-15-0500.1}, volume = {29}, year = {2016} } @article{Liang2019, author = {Liang, Yulian and Wang, Yongli and Zhao, Yinjun and Lu, Yuan and Liu, Xiaoying}, doi = {10.3390/w11051022}, journal = {Water}, number = {5}, pages = {1022}, title = {{Analysis and Projection of Flood Hazards over China}}, volume = {11}, year = {2019} } @article{https://doi.org/10.1002/joc.5548, abstract = {Persistent wet-freezing events (PWFEs), a typical type of compound extremes, combine adverse effects from both its precipitation and temperature components, thereby posing great threats to human society and ecosystem. Atmospheric circulation patterns that govern the occurrence and persistence of PWFEs over southern China are identified and classified, based on cases during 1980–2010. There are two dominating types of large-scale atmospheric circulation patterns responsible for PWFEs: a single blocking high type and a double blocking high type. The single blocking high type tends to occur under positive Arctic Oscillation (AO) phase, characteristics of a long-lived blocking high over the Lake Baikal in the middle troposphere favouring lower-level cold air masses penetrate southwards along a northeast–southwest route. Likewise, abundant water vapour advances northwards from the Bay of Bengal and the South China Sea, meeting cold air masses over southern China under the upper-level divergence caused by the intensified upper-level subtropical jet which prevails on top of the western Qinghai–Tibet Plateau. Locally, a stable temperature inversion structure is anchored in the lower troposphere. The double blocking high type features blocking highs over the Ural Mountains and the Sea of Okhotsk, along with an intensified trough between them. The upper-level subtropical jet over mid-latitude East Asia strengthens, providing divergence fields at upper troposphere. Low-level cold air masses move southwards from the Lake Baikal along a north route, converging with the water vapour transported from the Bay of Bengal to southern China by a low-level southwesterly jet. By contrast, the inversion layer is absent atop the region experiencing double blocking PWFEs.

Different from this short lasting but intense cold event in 2016, another cold event in the 2008 winter lasted much longer and occurred in tandem with freezing precipitation. Their differences in the duration and precipitation are essentially determined by differing behaviours of blocking highs at mid–high latitudes, the India–Burma Trough and the western Pacific subtropical high. The rapid southward invasion of cold air masses during the 2016 event resulted from the rapid decay of the blocking high, which emanated wave energies downstream and likewise lost wave energies to the local mean flow. By contrast, during the 2008 cold event, continuous upstream wave energy dispersion recurrently stimulated disturbances in the blocking domain, which then extracted energies from the mean flow efficiently to survive markedly longer. Moreover, in the 2008 case, the deepening of the India–Burma Trough and the westward extension of the western Pacific subtropical high jointly enhanced the moisture transport, leading to the freezing rain.

Cumulative 8-day (lag zero to seven days) relative risks (RRs) and 95{\%} confidence intervals were estimated, 1 and 2 standardized deviations above the medium (i.e., at 84.1th and 97.7th percentile, respectively), by comparing with Z scores for the lowest risks of mortality and outpatient visits as references. Analyses were performed for Taipei in north, Central Taiwan and Southern Taiwan. Results showed that standardized Z-values of high-temperature indices associated with the lowest health risk were approximately 0 in Taipei and Central Taiwan, and −1 in Southern Taiwan.

However despite a significant body of research, a knowledge and communication gap exists between scientists and non-scientists as to how climate change impact scenarios can be interpreted and what they imply for European forests. It is still challenging to advise forest decision makers on how best to plan for climate change as many uncertainties and unknowns remain and it is difficult to communicate these to practitioners and other decision makers while retaining emphasis on the importance of planning for adaptation. In this paper, recent developments in climate change observations and projections, observed and projected impacts on European forests and the associated uncertainties are reviewed and synthesised with a view to understanding the implications for forest management. Current impact assessments with simulation models contain several simplifications, which explain the discrepancy between results of many simulation studies and the rapidly increasing body of evidence about already observed changes in forest productivity and species distribution. In simulation models uncertainties tend to cascade onto one another; from estimating what future societies will be like and general circulation models (GCMs) at the global level, down to forest models and forest management at the local level. Individual climate change impact studies should not be uncritically used for decision-making without reflection on possible shortcomings in system understanding, model accuracy and other assumptions made. It is important for decision makers in forest management to realise that they have to take long-lasting management decisions while uncertainty about climate change impacts are still large. We discuss how to communicate about uncertainty - which is imperative for decision making - without diluting the overall message. Considering the range of possible trends and uncertainties in adaptive forest management requires expert knowledge and enhanced efforts for providing science-based decision support. {\textcopyright} 2014 Elsevier Ltd.}, author = {Lindner, Marcus and Fitzgerald, Joanne B. and Zimmermann, Niklaus E. and Reyer, Christopher and Delzon, Sylvain and van der Maaten, Ernst and Schelhaas, Mart-Jan and Lasch, Petra and Eggers, Jeannette and van der Maaten-Theunissen, Marieke and Suckow, Felicitas and Psomas, Achilleas and Poulter, Benjamin and Hanewinkel, Marc}, doi = {10.1016/j.jenvman.2014.07.030}, isbn = {0301-4797}, issn = {03014797}, journal = {Journal of Environmental Management}, keywords = {Climate change,Europe,Forest management,Forests,Uncertainty}, month = {dec}, pages = {69--83}, pmid = {25156267}, title = {{Climate change and European forests: What do we know, what are the uncertainties, and what are the implications for forest management?}}, url = {https://linkinghub.elsevier.com/retrieve/pii/S030147971400379X}, volume = {146}, year = {2014} } @article{Linsbauer2016a, abstract = {Surface digital elevation models (DEMs) and slope-related estimates of glacier thickness enable modelling of glacier-bed topographies over large ice-covered areas.

The modelled ice thicknesses are uncertain (±30{\%}), but spatial patterns of ice thickness and bed elevation primarily depend on surface slopes as derived from the DEM and, hence, are more robust. About 16 000 overdeepenings larger than 104m2 were detected in the modelled glacier beds, covering an area of {\~{}}2200 km2 and having a volume of {\~{}}120km3 (3-4{\%} of present-day glacier volume).

Wildfires are anticipated to be more frequent and intense under climate change. As a result, wildfires may emit more air pollutants that can harm health in communities in the future. The health impacts of wildfire smoke under climate change are largely unknown. Methods. We linked projections of future levels of fine particulate matter (PM2.5) specifically from wildfire smoke under the A1B climate change scenario using the GEOS-Chem model for 2046-2051, present-day estimates of hospital admission impacts from wildfire smoke, and future population projections to estimate the change in respiratory hospital admissions for persons ≥65 years by county (n = 561) from wildfire PM2.5 under climate change in the Western US. Results. The increase in intense wildfire smoke days from climate change would result in an estimated 178 (95{\%} confidence interval: 6.2, 361) additional respiratory hospital admissions in the Western US, accounting for estimated future increase in the elderly population. Climate change is estimated to impose an additional 4990 high-pollution smoke days. Central Colorado, Washington and southern California are estimated to experience the highest percentage increase in respiratory admissions from wildfire smoke under climate change. Conclusion. Although the increase in number of respiratory admissions from wildfire smoke seems modest, these results provide important scientific evidence of an often-ignored aspect of wildfire impact, and information on their anticipated spatial distribution. Wildfires can cause serious social burdens such as property damage and suppression cost, but can also raise health problems.

Instead, they promote the idea of a “storyline” approach, which asks complementary questions, such as “How much did climate change affect the severity of a given storm?” From the vantage of history and philosophy of science, a proposal to introduce a new approach or to answer different research questions—especially those of public interest—does not appear particularly controversial. However, the proposal proved highly controversial, with the majority of D{\&}A scientists reacting in a very negative and even personal manner. Some suggested the proposed alternatives amount to a weakening of standards, or an abandonment of scientific method. Here, we address the question: Why is this such a controversial proposition?

" It identifies a set of priority areas and sectors, but does not define which decision-making processes need what information, or why they need it.

El Oro province is a key dengue surveillance site, due to the high burden of dengue, seasonal transmission, co-circulation of all four dengue serotypes, and the recent introduction of chikungunya and Zika. In this study, we used climate forecasts to predict the evolution of the 2016 dengue season in the city of Machala, following one of the strongest El Ni{\~{n}}o events on record. Methods We incorporated precipitation, minimum temperature, and Ni{\~{n}}o3{\textperiodcentered}4 index forecasts in a Bayesian hierarchical mixed model to predict dengue incidence. The model was initiated on Jan 1, 2016, producing monthly dengue forecasts until November, 2016. We accounted for misreporting of dengue due to the introduction of chikungunya in 2015, by using active surveillance data to correct reported dengue case data from passive surveillance records. We then evaluated the forecast retrospectively with available epidemiological information. Findings The predictions correctly forecast an early peak in dengue incidence in March, 2016, with a 90{\%} chance of exceeding the mean dengue incidence for the previous 5 years. Accounting for the proportion of chikungunya cases that had been incorrectly recorded as dengue in 2015 improved the prediction of the magnitude of dengue incidence in 2016. Interpretation This dengue prediction framework, which uses seasonal climate and El Ni{\~{n}}o forecasts, allows a prediction to be made at the start of the year for the entire dengue season. Combining active surveillance data with routine dengue reports improved not only model fit and performance, but also the accuracy of benchmark estimates based on historical seasonal averages.

This study aims to determine evidence of responses in the durations of warm (WSDI) and cold (CSDI) spells to forcings external to the climate system. We consider the globe, the six continents and China during the period from 1958−2010 in this analysis. Here we compare the observed duration indices with those derived from simulated daily temperature by climate models participating in the Coupled Model Intercomparison Project Phase 5 (CMIP5), using an optimal fingerprint method. The results show that, averaged over the global lands, the WSDI has substantially increased by 15 days while the CSDI has decreased by 3 days over the 53 year period. The simulated changes are generally consistent with the observations; models, however, overestimate the observed changes in the WSDI in five of the six continental regions. We consider a signal is detected if it is significant at the 10{\%} level. At the global scale, human influences on both warm and cold spell durations are detected. At the continental scale, an anthropogenic signal is detected in the warm spell durations of most continents. The human influence on cold spell duration is detectable only in the Asian and European continents. In China, human influence can clearly be detected in both the warm and cold spell durations.

The RegCM model is used to develop high-resolution climate scenarios for the whole country of China driven by boundary conditions of the Geophysical Fluid Dynamics Laboratory (GFDL) model under the Representative Concentration Pathways (RCPs). RegCM performance on simulating the present climate over China is evaluated and the results indicate that it is capable of reproducing the spatial distributions of temperature and precipitation. Future projections from RegCM suggest that an increase of 2 °C in daily mean temperature is expected in China by the end of the twenty-first century under RCP4.5 while an increase of 4 °C would be seen under RCP8.5. The Tibetan Plateau is likely to expect the most substantial temperature increase as well as the most significant decrease in extreme cold climate in China. In comparison, the annual total precipitation over China is projected to increase by 58 mm/year at the end of the twenty-first century under RCP4.5 and by 71 mm/year under RCP8.5.

Adequate winter chill is an important site characteristic for commercial orchard operations, and quantifying chill is crucial for orchard management. Climate change may impact winter chill. With a view to adapting orchards to climate change, this review assesses the state of knowledge in modelling winter chill and the performance of various modelling approaches. It then goes on to present assessments of past and projected future changes in winter chill for fruit growing regions and discusses potential adaptation strategies. Some of the most common approaches to modelling chill, in particular the Chilling Hours approach, are very sensitive to temperature increases, and have also been found to perform poorly, especially in warm growing regions. The Dynamic Model offers a more complex but also more accurate alternative, and use of this model is recommended. Chill changes projected with the Dynamic Model are typically much less severe than those estimated with other models. Nevertheless, projections of future chill consistently indicate substantial losses for the warmest growing regions, while temperate regions will experience relatively little change, and cold regions may even see chill increases. Growers can adapt to lower chill by introducing low-chill cultivars, by influencing orchard microclimates and by applying rest-breaking chemicals. Given substantial knowledge gaps in tree dormancy, accurate models are still a long way off. Since timely adaptation is essential for growers of long-lived high-value perennials, alternative ways of adaptation planning are needed. Climate analogues, which are present-day manifestations of future projected climates, can be used for identifying and testing future-adapted species and cultivars. Horticultural researchers and practitioners should work towards the development and widespread adoption of better chill accumulation and dormancy models, for facilitating quantitatively appropriate adaptation planning. {\textcopyright} 2012 Elsevier B.V.}, author = {Luedeling, Eike}, doi = {10.1016/j.scienta.2012.07.011}, isbn = {0304-4238}, issn = {03044238}, journal = {Scientia Horticulturae}, keywords = {Adaptation,Chill Portions,Chilling Hours,Climate analogues,Dynamic Model,Tree dormancy}, month = {sep}, pages = {218--229}, publisher = {Elsevier}, title = {{Climate change impacts on winter chill for temperate fruit and nut production: A review}}, url = {https://www.sciencedirect.com/science/article/pii/S0304423812003305 https://linkinghub.elsevier.com/retrieve/pii/S0304423812003305}, volume = {144}, year = {2012} } @article{Lugon2010, author = {Lugon, Ralph and Stoffel, Markus}, doi = {10.1016/j.gloplacha.2010.06.004}, issn = {09218181}, journal = {Global and Planetary Change}, month = {sep}, number = {3-4}, pages = {202--210}, title = {{Rock-glacier dynamics and magnitude–frequency relations of debris flows in a high-elevation watershed: Ritigraben, Swiss Alps}}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0921818110001311}, volume = {73}, year = {2010} } @article{Luijendijk2018, abstract = {Coastal zones constitute one of the most heavily populated and developed land zones in the world. Despite the utility and economic benefits that coasts provide, there is no reliable global-scale assessment of historical shoreline change trends. Here, via the use of freely available optical satellite images captured since 1984, in conjunction with sophisticated image interrogation and analysis methods, we present a global-scale assessment of the occurrence of sandy beaches and rates of shoreline change therein. Applying pixel-based supervised classification, we found that 31{\%} of the world's ice-free shoreline are sandy. The application of an automated shoreline detection method to the sandy shorelines thus identified resulted in a global dataset of shoreline change rates for the 33 year period 1984-2016. Analysis of the satellite derived shoreline data indicates that 24{\%} of the world's sandy beaches are eroding at rates exceeding 0.5 m/yr, while 28{\%} are accreting and 48{\%} are stable. The majority of the sandy shorelines in marine protected areas are eroding, raising cause for serious concern. Coastal zones have historically attracted humans and human activities due to the abundant amenity, aesthetic value and diverse ecosystem services that they provide. As a result, the coastal zone all over the world has become heavily populated and developed 1-3 with 15 of the 20 megacities (population {\textgreater}10 million) of the world being located in the coastal zone. The global coastline is spatially highly variable and comprises several different types of coastal landforms, some examples being barrier islands, sea cliffs, tidal flats, and river deltas. Of these different coastline types, here we focus on sandy coasts, which are highly dynamic in time and space, and constitute a substantial part of world's coastline 4. As sandy coasts are highly developed and densely populated due to the amenity and aesthetics that they provide, erosion of these coasts over the last few decades is already resulting in coastal squeeze 5. Inevitably, climate change impacts on sandy coasts will only exacerbate this situation 6,7. Thus, reliable assessments of the occurrence of sandy coasts and their rates of shoreline change are basic necessities for effective spatial planning, sustainable coastal development, coastal engineering projects, and mitigation of climate change impacts along high value coastlines around the world.

Although many of the reviewed studies reported an increase in the intensity of high-impact wind speed and extreme cyclone frequency in the second half of the 21st century, the projections of aspects of future storminess over the NAER differed regionally. There is broad consensus that the frequency and intensity of storms, cyclones, and high-impact wind speed will increase over Central and Western Europe, and these changes will probably have the potential to produce more damage. In contrast, future extratropical storminess over Southern Europe is very likely to decrease. For Northern and Eastern Europe the results of the evaluation are inconclusive, because there is an indication of increasing as well as decreasing development of the evaluated aspects of future storminess.

Heat and cold indices have been utilized to adjust ambient temperature (Ta) for the effects of relative humidity (RH) or wind speed (WS) or both for the purposes of obtaining a "feels-like" or apparent temperature. However, no model has been found that incorporates adjustments for RH, WS, and radiation (RAD) over conditions that encompass hot and cold environmental conditions. The objective of this study was to develop a comprehensive climate index (CCI) that has application under a wide range of environmental conditions and provides an adjustment to Ta for RH, WS, and RAD. Environmental data were compiled from 9 separate summer periods in which heat stress events occurred and from 6 different winter periods to develop and validate the CCI. The RH adjustment is derived from an exponential relationship between Ta and RH with temperature being adjusted up or down from an RH value of 30{\%}. At 45 degrees C, the temperature adjustment for increasing RH from 30 to 100{\%} equals approximately 16 degrees C, whereas at -30 degrees C temperature adjustments due to increasing RH from 30 to 100{\%} equal approximately -3.0 degrees C, with greater RH values contributing to a reduced apparent temperature under cold conditions. The relationship between WS and temperature adjustments was also determined to be exponential with a logarithmic adjustment to define appropriate declines in apparent temperature as WS increases. With this index, slower WS results in the greatest change in apparent temperature per unit of WS regardless of whether hot or cold conditions exist. As WS increases, the change in apparent temperature per unit of WS becomes less. Based on existing windchill and heat indices, the effect of WS on apparent temperature is sufficiently similar to allow one equation to be utilized under hot and cold conditions. The RAD component was separated into direct solar radiation and ground surface radiation. Both of these were found to have a linear relationship with Ta. This index will be useful for further development of biological response functions, which are associated with energy exchange, and improving decision-making processes, which are weather-dependent.

The reconstruction included both absolute and relative sea level (RSL) in 11 km resolution over the period 1900–2014. The reconstructed monthly sea level had an average correlation of 96{\%} and root mean square error of 3.8 cm with 56 tide gauges independent of the statistical model. The statistical reconstruction of sea level was based on multiple linear regression and took land deformation information into account. An assessment of the quality of an open ocean altimetry product (ESA Sea Level CCI ECV, hereafter “the CCI”) in this regional sea was performed by validating the variability against the reconstruction as an independent source of sea level information. The validation allowed us to determine how close to the coast the CCI can be considered reliable. The CCI matched reconstructed sea level variability with correlation above 90{\%} and root-mean-square (RMS) difference below 6 cm in the southern and open part of the Baltic Proper. However, areas with seasonal sea ice and areas of high natural variability need special treatment. The reconstructed RSL change, which is important for coastal communities, was found to be dominated by isostatic land movements.

Global climate models have too coarse resolution to simulate hailstorms explicitly; thus it is unclear if a warmer climate will change hailstorm frequency and intensity, and if so, whether such events will become more likely through intensified thunderstorms or less likely owing to overall warmer conditions. Here we investigate hail generation and maintenance for warm-season extreme precipitation events in Colorado, USA, for both present-day and projected future climates using high-resolution model simulations capable of resolving hailstorms. Most simulations indicate a near-elimination of hail at the surface in future simulations for this region, despite more intense future storms and significantly larger amounts of hail generated in-cloud. An increase in the height of the environmental melting level due to climate warming is found to be the primary reason for the disappearance of surface hail, as the warmer atmosphere increases the melting of frozen precipitation. A decrease in future surface hail at high-elevation locations may imply potential changes in both hail damage and flood risk. {\textcopyright} 2012 Macmillan Publishers Limited.

Groundwater availability on Maui is affected by changes in climate and agricultural irrigation. To evaluate the availability of fresh groundwater under projected future climate conditions and changing agricultural irrigation practices, estimates of groundwater recharge are needed. A water-budget model with a daily computation interval was used to estimate the spatial distribution of recharge on Maui for one present-day and two future-climate scenarios. All three scenarios used 2017 land cover. The two future-climate scenarios, including one wetter than the present-day scenario and one drier than the present-day scenario, were developed using available high-resolution downscaled climate projections. The drier future scenario was developed using projections for a Representative Concentration Pathway warming scenario during 2071–99 with total radiative forcing of 8.5 Watts per square meter by the year 2100 (RCP8.5 2071–99 scenario), whereas the wetter future scenario was developed using projections for a “Special Report on Emissions Scenarios” A1B emission scenario during 2080–99 (A1B 2080–99 scenario). For the RCP8.5 2071–99 scenario, projected mean annual recharge decrease for Maui is about 172 million gallons per day, or about 14 percent less than present-day recharge, which is estimated to be 1,232 million gallons per day. Recharge for the RCP8.5 2071–99 scenario is projected to decrease in 22 of Maui's 25 aquifer systems, which are defined by the Hawaiʻi Commission on Water Resource Management. For the A1B 2080–99 future scenario, projected mean annual recharge increase for Maui is about 144 million gallons per day, or about 12 percent more than present-day recharge. Recharge for the A1B 2080–99 scenario is projected to increase in 17 of Maui's 25 aquifer systems. Between the two future scenarios, a total of 11 aquifer systems show similar direction in drying (Kahului, Kama‘ole, Lualaʻilua, Makawao, Olowalu, Pāʻia, Ukumehame, Waikapū) or wetting (Honopou, Kawaipapa, and Waikamoi) changes for recharge. Selectively modifying the climate inputs for the A1B 2080–99 scenario indicates that the projected changes in rainfall account for most of the projected changes in recharge for Maui's 25 aquifer systems. However, projected changes in reference evapotranspiration and forest-canopy evaporation also can account for a substantial part of the projected changes in recharge where changes in reference evapotranspiration are relatively large and where changes in forest-canopy evaporation extend across large forested areas.

In this study, we propose a framework to both characterise long-duration meteorological droughts that co-occur with extremely high temperatures and quantify their probability. We term these events as long-duration, dry and hot (DH) events and characterise them by their duration (D) and magnitude (M). D is defined as the consecutive number of days with precipitation below 1 mm, while M is the maximum daily maximum temperature during an event. A copula-based approach is then employed to estimate the probability of DH events. The framework is applied to Europe during the summer months of June, July and August. We also assess the change in probability that has occurred over the historical period 1950-2013 and find an increased probability of DH events throughout Europe where rising temperatures are found to be the main driver of this change. Dry periods are becoming hotter, leading to an increase in the occurrence of long-duration dry periods with extremely high temperatures. Some parts of Europe also show an increased probability of long-duration events although the relative change is not as strong as that seen with temperature. The results point to a predominant thermodynamic response of DH events to global warming and reaffirm previous research that soil moisture drought events are setting in faster and becoming more severe due to a change in the contributing meteorological hazards.

Several extreme hydrological events, some of them characterized as ‘once in a century', have been reported in the Amazon region during the last decade. While abundant rainfall in various sectors of the basin has determined extreme floods along the river's main stem in 1953, 1989, 1999, 2009, 2012–2015, deficient rainfall in 1912, 1926, 1963, 1980, 1983, 1995, 1997, 1998, 2005 and 2010 has caused anomalously low river levels, and an increase in the risk and number of fires in the region, with consequences for humans. This is consistent with changes in the variability of the hydrometeorology of the basin and suggests that extreme hydrological events have been more frequent in the last two decades. Some of these intense/reduced rainfalls and subsequent floods/droughts were associated (but not exclusively) with La Ni{\~{n}}a/El Ni{\~{n}}o events. In addition, moisture transport anomalies from the tropical Atlantic into Amazonia, and from northern to southern Amazonia alter the water cycle in the region year-to-year. We also assess the impacts of such extremes on natural and human systems in the region, considering ecological, economic and societal impacts in urban and rural areas, particularly during the recent decades.

This study focuses on an assessment of the future snow depth for two larger Alpine catchments. Automatic weather station data from two diverse regions in the Swiss Alps have been used as input for the Alpine3D surface process model to compute the snow cover at a 200m horizontal resolution for the reference period (1999–2012). Future temperature and precipitation changes have been computed from 20 downscaled GCM-RCM chains for three different emission scenarios, including one intervention scenario (2°C target) and for three future time periods (2020–2049, 2045–2074, 2070–2099). By applying simple daily change values to measured time series of temperature and precipitation, small-scale climate scenarios have been calculated for the median estimate and extreme changes. The projections reveal a decrease in snow depth for all elevations, time periods and emission scenarios. The non-intervention scenarios demonstrate a decrease of about 50{\%} even for elevations above 3000m. The most affected elevation zone for climate change is located below 1200m, where the simulations show almost no snow towards the end of the century. Depending on the emission scenario and elevation zone the winter season starts half a month to 1 month later and ends 1 to 3 months earlier in this last scenario period. The resulting snow cover changes may be roughly equivalent to an elevation shift of 500–800 or 700–1000m for the two non-intervention emission scenarios. At the end of the century the number of snow days may be more than halved at an elevation of around 1500m and only 0–2 snow days are predicted in the lowlands. The results for the intervention scenario reveal no differences for the first scenario period but clearly demonstrate a stabilization thereafter, comprising much lower snow cover reductions towards the end of the century (ca. 30{\%} instead of 70{\%}).}, author = {Marty, Christoph and Schl{\"{o}}gl, Sebastian and Bavay, Mathias and Lehning, Michael}, doi = {10.5194/tc-11-517-2017}, isbn = {1994-0416}, issn = {1994-0424}, journal = {The Cryosphere}, month = {feb}, number = {1}, pages = {517--529}, title = {{How much can we save?

Analysis of an alpine peat mire showed that rapid industrial and agricultural development (both pastoral and cropping) over the past 200 years has resulted in significant environmental change in Australia. Beginning in the 1880s, rates of wind erosion and metal enrichment were up to 10 and 30 times that of background natural conditions, respectively. Increased dust deposition and an expansion in dust source areas were found to map the progression of European farming across the continent, while dust deposition pulses in the mire matched known land degradation events. After 1990 dust deposition decreased, returning to pre-1880 rates. This was attributed to three factors: net soil loss following more than a century of agricultural activity, increased environmental awareness and soil conservation, and changing windiness. Metal enrichment in the mire reached approximately 2 times natural background accumulation rates by the 1980s as Australia's mining industry expanded. However, metal enrichment continued to increase after the 1980s reaching an average of {\~{}}5 times background rates by 2006 and reflecting increased mineral resource development in Australia.

We partition the total uncertainty into the individual contributions caused by glacier models, general circulation models, RCPs, and natural variability. We find that emission scenario uncertainty is growing throughout the 21st century and is the largest source of uncertainty by 2100.

Here, we review some recent advances in the study of the main components of the cryosphere in the Andes, and discuss the changes observed in the seasonal snow and permanent ice masses of this region over the past decades. The open access and increasing availability of remote sensing products has produced a substantial improvement in our understanding of the current state and recent changes of the Andean cryosphere, allowing an unprecedented detail in their identification and monitoring at local and regional scales. Analyses of snow cover maps has allowed the identification of seasonal patterns and long term trends in snow accumulation for most of the Andes, with some sectors in central Chile and central-western Argentina showing a clear decline in snowfall and snow persistence since 2010. This recent shortage of mountain snow has caused an extended, severe drought that is unprecedented in the hydrological and climatological records from this region. Together with data from global glacier inventories, detailed inventories at local/regional scales are now also freely available, providing important new information for glaciological, hydrological, and climatological assessments in different sectors of the Andes. Numerous studies largely based on field measurements and/or remote sensing techniques have documented the recent glacier shrinkage throughout the Andes. This observed ice mass loss has put Andean glaciers among the highest contributors to sea level rise per unit area. Other recent studies have focused on rock glaciers, showing that in extensive semi-arid sectors of the Andes these mountain permafrost features contain large reserves of freshwater and may play a crucial role as future climate becomes warmer and drier in this region. Many relevant issues remain to be investigated, however, including an improved estimation of ice volumes at local scales, and detailed assessments of the hydrological significance of the different components of the cryosphere in Andean river basins. The impacts of future climate changes on the Andean cryosphere also need to be studied in more detail, considering the contrasting climatic scenarios projected for each region. The sustained work of various monitoring programs in the different Andean countries is promising and will provide much needed field observations to validate and improve the analyses made from remote sensors and modeling techniques. In this sense, the development of a well-coordinated network of high-elevation hydro-meteorological stations appears as a much needed priority to complement and improve the many glaciological and hydro-climatological assessments that are being conducted across the Andes.}, author = {Masiokas, M.

At the lake-wide scale we found declining ice duration and warming LSSWT patterns consistent with previous studies. At the lake sub-basin scale, our statistical models identified distinct warming trends within each lake that included significant breakpoints in ice duration for 13 sub-basins, consistent linear declines in 11 sub-basins, and no trends in 4 sub-basins. At the finest scale, we found that the northern- and eastern-most portions of each Great Lake, especially in nearshore areas, have experienced faster rates of LSSWT warming and shortening ice duration than those previously reported from trends at the lake scale.

Prior studies of OA's potential impacts on human communities have focused only on possible direct economic losses from specific scenarios of human dependence on commercial harvests and damages to marine species. However, other economic and social impacts, such as changes in food security or livelihoods, are also likely to result from climate change. This study evaluates patterns of dependence on marine resources within Alaska that could be negatively impacted by OA and current community characteristics to assess the potential risk to the fishery sector from OA. Here, we used a risk assessment framework based on one developed by the Intergovernmental Panel on Climate Change to analyze earth-system global ocean model hindcasts and projections of ocean chemistry, fisheries harvest data, and demographic information. The fisheries examined were: shellfish, salmon and other finfish. The final index incorporates all of these data to compare overall risk among Alaska's federally designated census areas. The analysis showed that regions in southeast and southwest Alaska that are highly reliant on fishery harvests and have relatively lower incomes and employment alternatives likely face the highest risk from OA.

We analyze their temporal evolution and variability from 1979–2013, based on daily station data and ERA-Interim reanalysis. Calculated trends from both datasets suggest a widespread decrease of cold spells in winter and summer of up to −4 days/decade, with regional patches where trends are statistically significant throughout the Arctic. Winter trends are spatially heterogeneous, the reanalysis also shows small areas with statistically significant increases of cold spells throughout Siberia. Calculated changes in warm spells from both datasets are mostly small throughout the Arctic (less than ±1 day/decade) and statistically not significant. Remarkable exceptions are the Lena river basin in winter with a statistically significant decrease of up to −1.5 days/decade and areas in Scandinavia with statistically significant increases of up to 2.5 days/decade in winter and summer (again from both datasets). From the analysis of spell lengths, we find that there are no shifts from longer to shorter spells or vice versa with time, but long cold spells (events lasting for more than 15 days) disappear almost completely after the year 2000.

We use analogs and the extreme South Asian heat of 2015 as a focusing event to help interpret the increasing frequency of deadly heat under specified amounts of global warming. Using a large ensemble of climate models, our results confirm that global mean air temperature is nonlinearly related to heat stress, meaning that the same future warming as realized to date could trigger larger increases in societal impacts than historically experienced. This nonlinearity is higher for heat stress metrics that integrate the effect of rising humidity. We show that, even in a climate held to 2 °C above PI, Karachi (Pakistan) and Kolkata (India) could expect conditions equivalent to their deadly 2015 heatwaves every year. With only 1.5 °C of global warming, twice as many megacities (such as Lagos, Nigeria, and Shanghai, China) could become heat stressed, exposing more than 350 million more people to deadly heat by 2050 under a midrange population growth scenario.

For instance, the outdoor comfort assessment has shown that there is a strong link between biometeorology and architecture and urban climate. Additionally, to address the challenges of the energy transition, there will be a convergence of the energy needs in the future with an energy nexus regrouping the energy demand of urban areas. It is also highlighted that the uncertainty related to future climatic data makes urban adaptation and mitigation strategies complex to implement and to design given the lack of a comprehensive framework.

Heat should therefore not be conflated with high temperatures. A range of empirical, direct and rational heat stress indices have been developed to assess heat stress.

Some have suggested that sea‐level rise has already resulted in widespread erosion and inundation of atoll islands. Here, we analyze the physical changes in over 200 islands on 12 atolls in the central and western Pacific in the past few decades when sea level in the region increased at rates three to four times the global average. Results show little evidence of heightened erosion or reduction in island size. Instead island shores have adjusted their position and morphology in response to human impacts such as seawall construction and to variations in climate–ocean processes. These changes are reviewed and the role of sea‐level rise is evaluated. The implications of this analysis are addressed in two parts. First, we consider the proposition that future sea‐level rise will destabilize atoll islands to such an extent that their inhabitants will be forced to migrate offshore. And second, we identify a series of new challenges relating to risk reduction and adaptation policy for atoll island governments, international agencies, and island communities.

A case study evaluating flood risk in Westport is used to demonstrate the methods. Hence this paper has a dual purpose to explain the modelling methods and to provide a flood risk assessment for Westport under selected climate change scenarios. We show how physically-based climate, hydrological and hydrodynamic models can be used together to simulate changes in meteorological and hydrological processes under future climates, and evaluate the effect of those changes on projections of flood inundation and risks to people and assets. Using a historic 1-in-50 year event as a baseline, we predicted how the severity of that event would change under each climate scenario. Statistically downscaled projections from Global Climate Models were used to define appropriate adjustments to the historical rainfall and temperature measurements. Using the hydrological model TopNet, this data was used to simulate flood hydrographs at the Te Kuha gauging station upstream of Westport. The resulting hydrographs predicted for the future time period 2080-2099 correspond to events in the current climate with recurrence intervals of 78, 98 and 113 years for the B1, A1B and A2 IPCC SRES scenarios respectively. The flood hydrographs provided upstream boundary conditions for a 2D hydrodynamic model simulating inundation of the Buller floodplain. Predictions for inundated area increase from 50{\%} of Westport town in the current climate to 67{\%}, 70{\%}, and 72{\%} for the B1, A1B and A2 scenarios for the 2080-2099 time period. Resulting maps of inundation depths and velocities allow detailed planning for mitigation of flood events. We used the hazard assessment tool RiskScape to calculate the impact of the flood on people and assets (buildings, contents and vehicles) within the inundated area.

These can be divided into those directly related to climatic change, contributing to an expansion in the tick's geographic range at extremes of altitude in central Europe, and at extremes of latitude in Scandinavia; those related to changes in the distribution of tick hosts, particularly roe deer and other cervids; other ecological changes such as habitat connectivity and changes in land management; and finally, anthropogenically induced changes. These factors are strongly interlinked and often not well quantified. Although a change in climate plays an important role in certain geographic regions, for much of Europe it is non-climatic factors that are becoming increasingly important. How we manage habitats on a landscape scale, and the changes in the distribution and abundance of tick hosts are important considerations during our assessment and management of the public health risks associated with ticks and tick-borne disease issues in 21(st) century Europe. Better understanding and mapping of the spread of I. ricinus (and changes in its abundance) is, however, essential to assess the risk of the spread of infections transmitted by this vector species.

The global studies lack the specificity to inform decision making, while the local studies do little to clarify potential changes over large regions (major river basins, states, or groups of states), a scale often important in the development of water policy. An analysis of the potential impact of climate change on groundwater recharge across the western United States (west of 100° longitude) is presented synthesizing existing studies and applying current knowledge of recharge processes and amounts. Eight representative aquifers located across the region were evaluated. For each aquifer published recharge budget components were converted into four standard recharge mechanisms: diffuse, focused, irrigation, and mountain-systems recharge. Future changes in individual recharge mechanisms and total recharge were then estimated for each aquifer. Model-based studies of projected climate-change effects on recharge were available and utilized for half of the aquifers. For the remainder, forecasted changes in temperature and precipitation were logically propagated through each recharge mechanism producing qualitative estimates of direction of changes in recharge only (not magnitude). Several key patterns emerge from the analysis. First, the available estimates indicate average declines of 10-20{\%} in total recharge across the southern aquifers, but with a wide range of uncertainty that includes no change. Second, the northern set of aquifers will likely incur little change to slight increases in total recharge. Third, mountain system recharge is expected to decline across much of the region due to decreased snowpack, with that impact lessening with higher elevation and latitude. Factors contributing the greatest uncertainty in the estimates include: (1) limited studies quantitatively coupling climate projections to recharge estimation methods using detailed, process-based numerical models; (2) a generally poor understanding of hydrologic flowpaths and processes in mountain systems; (3) difficulty predicting the response of focused recharge to potential changes in the frequency and intensity of extreme precipitation events; and (4) unconstrained feedbacks between climate, irrigation practices, and recharge in highly developed aquifer systems.}, author = {Meixner, Thomas and Manning, Andrew H. and Stonestrom, David A. and Allen, Diana M. and Ajami, Hoori and Blasch, Kyle W. and Brookfield, Andrea E. and Castro, Christopher L. and Clark, Jordan F. and Gochis, David J. and Flint, Alan L. and Neff, Kirstin L. and Niraula, Rewati and Rodell, Matthew and Scanlon, Bridget R. and Singha, Kamini and Walvoord, Michelle A.}, booktitle = {Journal of Hydrology}, doi = {10.1016/j.jhydrol.2015.12.027}, issn = {00221694}, keywords = {Climate change,Groundwater recharge,Recharge mechanisms,Western United States}, month = {mar}, pages = {124--138}, publisher = {Elsevier B.V.}, title = {{Implications of projected climate change for groundwater recharge in the western United States}}, volume = {534}, year = {2016} } @article{Mekis2015, author = {Mekis, {\'{E}}va and Vincent, Lucie A. and Shephard, Mark W. and Zhang, Xuebin}, doi = {10.1080/07055900.2015.1086970}, issn = {0705-5900}, journal = {Atmosphere-Ocean}, month = {aug}, number = {4}, pages = {383--397}, title = {{Observed Trends in Severe Weather Conditions Based on Humidex, Wind Chill, and Heavy Rainfall Events in Canada for 1953–2012}}, url = {http://www.tandfonline.com/doi/full/10.1080/07055900.2015.1086970}, volume = {53}, year = {2015} } @article{Melchiorre2012, author = {Melchiorre, Caterina and Frattini, Paolo}, doi = {10.1007/s10584-011-0325-0}, issn = {0165-0009}, journal = {Climatic Change}, month = {jul}, number = {2}, pages = {413--436}, title = {{Modelling probability of rainfall-induced shallow landslides in a changing climate, Otta, Central Norway}}, url = {http://link.springer.com/10.1007/s10584-011-0325-0}, volume = {113}, year = {2012} } @article{Melet2018, abstract = {Coastal communities are threatened by sea-level changes operating at various spatial scales; global to regional variations are associated with glacier and ice sheet loss and ocean thermal expansion, while smaller coastal-scale variations are also related to atmospheric surges, tides and waves.

Low and high runoff conditions were defined as occurrences that fall outside the 10th (low values) and 90th (high values) percentile values of the period of record. SnowModel and HydroFlow modeling tools were used at 4-km horizontal grid increments and 3-h time intervals.

This modeling system includes evaporation and sublimation from snow-covered surfaces, but it does not take into account evapotranspiration from bare and vegetation-covered soils and from river and lake surfaces. In general for the Andes Cordillera, the simulated runoff decreased before 1997 and increased afterward. This could be due to a model precipitation artifact in the MERRA forcing. If so, this artifact would influence the number of years with low runoff values, which decreased over time, while the number of high runoff values increased over time. For latitudes south of {\~{}}40°S, both the greatest decrease in the number of low runoff values and the greatest increase in high runoff values occurred. High runoff values averaged 84{\%} and 58{\%} higher than low values for nonglacierized and glacierized catchments, respectively. Furthermore, for glacierized catchments, 61{\%} and 62{\%} of the runoff originated from rain-derived runoff during low and high runoff extreme years, respectively; 28{\%} and 30{\%} from snowmelt-derived runoff; and 11{\%} and 8{\%} from glacier-ice-melt-derived runoff.

We find that the 2000s had the highest number of mean annual air temperature (MAAT) warm extremes, and the 1890s the highest number of cold extremes, and that a high (low) positive North Atlantic Oscillation (NAO) Index equals a high number of cold (warm) extreme events. For the 2000s the number of warm extremes was significantly higher by around 50{\%} than the number in the 1940s (the early twentieth century warm period): the latter being the decade with the second highest occurrence of MAAT warm extremes. Since 1960, based on MAAT the number of cold extremes has overall decreased on the decadal timescale, besides a peak in 1980s, while warm extremes have increased, leading to a higher occurrence of extremes (cold plus warm extremes): an almost similar pattern occurred for monthly mean temperatures and monthly mean daily maximum and minimum temperature datasets.

The consequences of such mismatches are difficult to link to specific future climate change scenarios because the responses across trophic levels have complex underlying climate drivers often confounded by other stressors. In contrast, seasonal coat color polyphenism creating camouflage against snow is a direct and potentially severe type of seasonal mismatch if crypsis becomes compromised by the animal being white when snow is absent. It is unknown whether plasticity in the initiation or rate of coat color change will be able to reduce mismatch between the seasonal coat color and an increasingly snow-free background. We find that natural populations of snowshoe hares exposed to 3 y of widely varying snowpack have plasticity in the rate of the spring white-to-brown molt, but not in either the initiation dates of color change or the rate of the fall brown-to-white molt. Using an ensemble of locally downscaled climate projections, we also show that annual average duration of snowpack is forecast to decrease by 29-35 d by midcentury and 40-69 d by the end of the century. Without evolution in coat color phenology, the reduced snow duration will increase the number of days that white hares will be mismatched on a snowless background by four- to eightfold by the end of the century.

There are multiple barriers to climate adaptation, including among others: the lack of the public understanding of risks, lack of leadership and availability of resources to adapt. In this study, we assess to what extent coastal residents understand their properties' flood risk, and what predicts their risk perception and adaptation behaviour. We surveyed 420 individuals in South East Queensland projected to be within the permanent or temporary flood zone in 2100 based on combined sea-level rise and storm surge scenarios. We assessed the correlations between the projected (i.e. objective) and perceived risk of inundation, adaptation behaviour, and the individual characteristics considered to influence risk perception and adaptation. While we found a correlation between perceived and some objective flood risks, perceived risk only partially reflected objective risk. Other factors that influenced risk perception were previous experience of flooding events, belief in climate change, risk aversion, age and gender. Factors driving risk perception varied with the type (permanent, temporary) and frequency of flooding event (1 in 20 or 1 in 100 years). Previous experience with extreme event impacts and belief in climate change influenced all future perceived risks. However, even after being impacted by an extreme event, adaptation was moderate (58 {\%}). Personal as well as environmental factors influence the likelihood of adaptation. The moderate adaptation response within our case study is likely a result of most respondents considering large flooding events to be rare and of limited impact, and anticipating future government aid to overcome flooding damage costs.

The coastal zone of the Pacific mountain ranges is characterized by abundant snowfall, higher snow densities, and higher temperatures. The continental zone of the Colorado Rockies is characterized by lower temperatures, lower snowfall, lower snow densities, higher snow temperature gradients, and a more persistently unstable snowpack resulting from depth hoar. The intermountain zone of Utah, Montana, and Idaho is intermediate between the other two zones. A quantitative analysis of snow avalanche climate of the region was conducted based on Westwide Avalanche Network data from 1969 to 1995. A binary avalanche climate classification, based on well-known thresholds and ranges of snowpack and climatic variables, illustrates the broadscale climatology of the three major zones, some spatially heterogeneous patterns, and variations with elevation. Widespread spatial shifts toward more coastal conditions occurred during 1985/86 and 1991/92, and shifts toward more continental conditions occurred during 1976/77 and 1987/88. Height anomalies at 500 mb explain many of these shifts, but daily plots of climate and avalanche variables during seasonal extremes for sites in northern Utah also illustrate the importance of understanding snowpack and weather variations that occur at daily to weekly timescales.

Regional climate projections can be useful to quantify climate change impacts on renewable energies. With this aim, we analyze future changes of wind speed and wind energy potentials using a multimodel ensemble of EURO-CORDEX simulations at 12 km and three-hourly resolution, considering nine different global and regional climate model chains. A comparison between modeled historical 10 m wind speeds and ERA-Interim-driven evaluation runs for the same regional climate models uncovers some substantial model biases. The bias-corrected 10 m wind speeds are extrapolated to the hub height of a wind turbine to derive gridded wind energy output (Eout). The ensemble mean responses project only small changes of mean annual and winter Eout for large parts of Europe in future decades, but a considerable decrease for summer Eout. In terms of variability, increasing intraannual and interdaily variabilities are projected for large parts of northern, central, and eastern Europe. While the ensemble spread is quite large for interdaily variability, results are more robust for intraannual variability. With respect to wind speed characteristics relevant for wind energy production, a robust increase in the occurrence of low wind speeds ({\textless}3 m/s) is detected. Due to a combination of higher annual mean Eout and lower intraannual variability, climate change could be beneficial for regions like Baltic and Aegean Sea. For large parts of Germany, France, and Iberia, a lower mean Eout and increased intraannual variability may imply larger temporal/spatial fluctuations in future wind energy production and therefore a more challenging wind energy management.}, author = {Moemken, Julia and Reyers, Mark and Feldmann, Hendrik and Pinto, Joaquim G}, doi = {10.1029/2018JD028473}, issn = {2169897X}, journal = {Journal of Geophysical Research: Atmospheres}, month = {jun}, number = {12}, pages = {6373--6389}, title = {{Future Changes of Wind Speed and Wind Energy Potentials in EURO-CORDEX Ensemble Simulations}}, url = {http://doi.wiley.com/10.1029/2018JD028473}, volume = {123}, year = {2018} } @article{Mohammed2018, author = {Mohammed, Khaled and {Saiful Islam}, A.

Where they co-exist, Mytilus dominates the high and Perna the low mussel zone, overlapping in the middle. Mytilus generally exhibits high individual reproductive output, but feeding time is reduced, physical conditions are stressful and adult densities are lower on the higher shore. We compared overall reproductive potential of populations of the two species using a 1-year data set for three sites, accounting for within-shore distribution and abundances. Despite the restriction of Mytilus to the more stressful upper-shore, its aggregate reproductive potential was comparable to that of Perna. We then used Dynamic Energy Budget modelling to test the effects of changing conditions by calculating aggregate reproductive potential under temperature conditions predicted for the end of the century by the International Panel on Climate Change. The results suggest increased aggregate reproductive potential for both species, but the effect was stronger for the native species at two of three sites, implying increased biotic resistance by Perna to the further spread of Mytilus.

Spatial information and other attributes (e.g., presence of coastal protection works and backshore development) of the beaches of the 58 largest islands of the archipelago were obtained on the basis of remote-sensed images available on the web. Ranges of SLR-induced beach retreats under different morphological, sedimentological and hydrodynamic forcing, and SLR scenarios were estimated using suitable ensembles of cross-shore (1-D) morphodynamic models. These ranges, combined with empirically derived estimations of wave run-up induced flooding, were then compared with the recorded maximum beach widths to provide ranges of retreat/erosion and flooding at the archipelago scale. The spatial information shows that the Aegean pocket beaches may be particularly vulnerable to mean sea level rise (MSLR) and episodic SLRs due to (i) their narrow widths (about 59{\%} of the beaches have maximum widths {\textless}20m), (ii) their limited terrestrial sediment supply, (iii) the substantial coastal development and (iv) the limited existing coastal protection. Modeling results indeed project severe impacts under mean and episodic SLRs, which by 2100 could be devastating.

Overall, most of the changes over the sub-basins suggest moister conditions with increasing temperatures.

Emphasis will be placed on the workflow making it possible to analyze the data with various levels of aggregation (from daily data to annual scale indicators, to their statistical moments accounting for multiple climate scenarios and lead times), in order to address the needs of various stakeholders, at the European, national, regional and local scales. The data will be made available freely through the Copernicus Data Store in various ways (download of raw data, download or graphics based on post-processed information accounting for user specific needs). It is expected that the data and the tools developed within this project will not only make it possible to analyze the climate sensitivity of ski tourism in Europe as a topical yet academic research question, but would also help third-parties in developing climate services specifically targeting the ski tourism industry in Europe.

Here we integrate global fire datasets and environmental covariates to build spatial statistical models of fire probability at a 0.58 resolution and examine environmental controls on fire activity. Fire models are driven by climate norms from 16 GCMs (A2 emissions scenario) to assess the magnitude and direction of change over two time periods, 2010–2039 and 2070–2099. From the ensemble results, we identify areas of consensus for increases or decreases in fire activity, as well as areas where GCMs disagree. Although certain biomes are sensitive to constraints on biomass productivity and others to atmospheric conditions promoting combustion, substantial and rapid shifts are projected for future fire activity across vast portions of the globe. In the near term, the most consistent increases in fire activity occur in biomes with already somewhat warm climates; decreases are less pronounced and concentrated primarily in a few tropical and subtropical biomes. However, models do not agree on the direction of near- term changes across more than 50{\%} of terrestrial lands, highlighting major uncertainties in the next few decades. By the end of the century, the magnitude and the agreement in direction of change are projected to increase substantially. Most far-term model agreement on increasing fire probabilities (;62{\%}) occurs at mid- to high-latitudes, while agreement on decreasing probabilities (;20{\%}) is mainly in the tropics. Although our global models demonstrate that long-term environmental norms are very successful at capturing chronic fire probability patterns, future work is necessary to assess how much more explanatory power would be added through interannual variation in climate variables. This study provides a first examination of global disruptions to fire activity using an empirically based statistical framework and a multi-model ensemble of GCM projections, an important step toward assessing fire-related vulnerabilities to humans and the ecosystems upon which they depend.

Hydrodynamic modelling of wave and current behaviour as well as contemporaneous sand transport shows the east to north-east storm wave direction to be the major determinant of erosion magnitude. This arises because of reduced energy attenuation across the continental shelf and the focussing of wave energy on coastal sections not equilibrated with such wave exposure under the prevailing south-easterly wave climate. Narrabeen–Collaroy, a well-known erosion hot spot on Sydney's Northern Beaches, is shown to be particularly vulnerable to storms from this direction because the destructive erosion potential is amplified by the influence of the local embayment geometry.

We find a large increase in the fraction of locations that posted decreasing trends, and averaged across the western US, the decline in average April 1 snow water equivalent since mid-century is roughly 15–30{\%} or 25–50 km3, comparable in volume to the West's largest man-made reservoir, Lake Mead.

A team of researchers from Oregon State University and UCLA found that spring snowpack declined almost everywhere, especially in the coastal states and other locations with mild winter climate.

The Canadian Sea Ice and Snow Evolution (CanSISE) Network is a climate research network focused on developing and applying state of the art observational data to advance dynamical prediction, projections, and understanding of seasonal snow cover and sea ice in Canada and the circumpolar Arctic. Here, we present an assessment from the CanSISE Network on trends in the historical record of snow cover (fraction, water equivalent) and sea ice (area, concentration, type, and thickness) across Canada. We also assess projected changes in snow cover and sea ice likely to occur by mid-century, as simulated by the Coupled Model Intercomparison Project Phase 5 (CMIP5) suite of Earth system models. The historical datasets show that the fraction of Canadian land and marine areas covered by snow and ice is decreasing over time, with seasonal and regional variability in the trends consistent with regional differences in surface temperature trends. In particular, summer sea ice cover has decreased significantly across nearly all Canadian marine regions, and the rate of multi-year ice loss in the Beaufort Sea and Canadian Arctic Archipelago has nearly doubled over the last 8 years. The multi-model consensus over the 2020–2050 period shows reductions in fall and spring snow cover fraction and sea ice concentration of 5–10 {\%} per decade (or 15–30 {\%} in total), with similar reductions in winter sea ice concentration in both Hudson Bay and eastern Canadian waters.

Our analyses also show that climate change has increased the probability of extremely long growing seasons by a factor of 25, and decreased the probability of extremely short growing seasons. A lengthening of the growing season in regions with these mostly rain-fed crops could improve yields, provided that water availability does not become an issue. An expansion of areas with more than 150. days of growing season into the northern latitudes makes more land potentially available for planting wheat and maize. Furthermore, double-cropping can become an alternative to current practices in areas with very long growing seasons which are also shown to increase with a warming climate.

There are different types of drought being studied, such as meteorological, agricultural, hydrological, and socioeconomic droughts; however, a lack of unanimous definition complicates drought study. Drought indices are used as proxies to track and quantify droughts; therefore, accurate formulation of robust drought indices is important to investigate drought characteristics under the warming climate. Because different drought indices show different degrees of sensitivity to the same level of continental warming, robustness of drought indices against change in temperature and other variables should be prioritized. A formulation of drought indices without considering the factors that govern the background state may lead to drought artifacts under a warming climate. Consideration of downscaling techniques, availability of climate data, estimation of potential evapotranspiration (PET), baseline period, non-stationary climate information, and anthropogenic forcing can be additional challenges for a reliable drought assessment under climate change. As one formulation of PET based on temperatures can lead to overestimation of future drying, estimation of PET based on the energy budget framework can be a better approach compared to only temperature-based equations. Although the performance of drought indicators can be improved by incorporating reliable soil moisture estimates, a challenge arises due to limited reliable observed data for verification.

Although heat exposure during the night is anecdotally cited as being important, this has not been rigorously demonstrated in the epidemiological literature. Methods: We quantified the contribution of nighttime temperatures using time-series quasi-Poisson regression on cause and age-specific daily mortality in London between 1993 and 2015. Daytime and nighttime exposures were characterized by average temperatures between 9 am and 9 pm and between 4 am and 8 am, respectively, lagged by 7 days. We also examined the differential impacts of hot and cool nights preceded by very hot days. All models were adjusted for air quality, season, and day of the week. Nighttime models were additionally adjusted for daytime exposure. Results: Effects from nighttime exposure persisted after adjusting for daytime exposure. This was highest for stroke, RR (relative risk) = 1.65 (95{\%} confidence interval (CI) = 1.27 to 2.14) estimated by comparing mortality risk at the 80th and 99th temperature percentiles. Compared to daytime exposure, nighttime exposure had a higher mortality risk on chronic ischemic and stroke and in the younger age groups. Respiratory mortality was most sensitive to daytime temperatures. Hot days followed by hot nights had a greater mortality risk than hot days followed by cool nights. Conclusions: Nighttime exposures make an additional important contribution to heat-related mortality.

Res. Lett. 13 (2018) 065019 Abstract The Paris Agreement achieved in December 2015 established that the signatory countries should pursue to hold the increase in global average temperature to below 2 • C relative to the preindustrial period and to strive to limit the temperature increase to 1.5 • C below the preindustrial period. The potential changes in tropical cyclones over the basin making landfall over southern Africa under the key global temperature goals have not been thoroughly investigated. Using the Coordinated Regional Downscaling Experiment-Africa regional climate models, we downscale six global climate models of the Coupled Model Inter-comparison Project Phase 5 to high resolution. This serves towards studying changes in tropical cyclone tracks over the South West Indian Ocean under different extents of global warming (1.5 • C, 2 • C and 3 • C of warming with respect to pre-industrial conditions). It is projected that the number of tropical cyclones making landfalls over southern Africa under global warming will decrease, with 2 • C being a critical threshold, after which the rate of cyclone frequency with further temperature increases no longer has a diminishing effect. Fewer cyclones may bring benefits and reduce damage to the southern African region. Although a decrease in damages associated with flood events is desirable, general decreases in tropical cyclone and tropical lows may also be associated with decreased rainfall over the Limpopo River basin and southern, central and northern Mozambique (with negative impacts on dryland agriculture).}, author = {Muthige, M S and Malherbe, J and Englebrecht, F A and Grab, S and Beraki, A and Maisha, T R and {Van der Merwe}, J}, doi = {10.1088/1748-9326/aabc60}, isbn = {1748-9326}, issn = {1748-9326}, journal = {Environmental Research Letters}, keywords = {global warming,precipitation,tropical cyclones}, month = {jun}, number = {6}, pages = {065019}, publisher = {IOP Publishing}, title = {{Projected changes in tropical cyclones over the South West Indian Ocean under different extents of global warming}}, url = {https://doi.org/10.1088/1748-9326/aabc60}, volume = {13}, year = {2018} } @article{Myers2017, abstract = {Great progress has been made in addressing global undernutrition over the past several decades, in part because of large increases in food production from agricultural expansion and intensification.

Yet, many climate change studies ignore animal behaviour. Furthermore, our current knowledge of how global change alters animal behaviour is mostly restricted to single species, life phases and stressors, leading to an incomplete view of how coinciding climate stressors can affect the ecological interactions that structure biological communities.

We demonstrate how pervasive the effects of global change are on a wide range of critical behaviours that determine the persistence of species and their success in ecological communities. We then evaluate several approaches to studying the ecological effects of warming and acidification, and identify knowledge gaps that need to be filled, to better understand how global change will affect marine populations and communities through altered animal behaviours.

Derived from multiple ecosystems and latitudes, our metaanalysis of 632 published experiments quantified the direction and magnitude of ecological change resulting from ocean acidification and warming to conceptualize broadly based change. Primary production by temperate noncalcifying plankton increases with elevated temperature and CO2, whereas tropical plankton decreases productivity because of acidification. Temperature increases consumption by and metabolic rates of herbivores, but this response does not translate into greater secondary production, which instead decreases with acidification in calcifying and noncalcifying species. This effect creates a mismatch with carnivores whose metabolic and foraging costs increase with temperature. Species diversity and abundances of tropical as well as temperate species decline with acidification, with shifts favoring novel community compositions dominated by noncalcifiers and microorganisms. Both warming and acidification instigate reduced calcification in tropical and temperate reef-building species. Acidification leads to a decline in dimethylsulfide production by ocean plankton, which as a climate gas, contributes to cloud formation and maintenance of the Earth's heat budget. Analysis of responses in short- and long-term experiments and of studies at natural CO2 vents reveals little evidence of acclimation to acidification or temperature changes, except for microbes.

These floods caused extensive damage, killing people and livestock as well as destroying property and crops. Using satellite data analysis and field surveys of this area, we find that the water volume that drained at Kashkasuu glacial lake in 2006 was 194 000 m3, at western Zyndan lake in 2008 was 437 000m3, at Jeruy lake in 2013 was 182 000m3, and at Karateke lake in 2014 was 123 000m3. Due to their subsurface outlet, we refer to these short-lived glacial lakes as the "tunnel-type", a type that drastically grows and drains over a few months. From spring to early summer, these lakes either appear, or in some cases, significantly expand from an existing lake (but non-stationary), and then drain during summer. Our field surveys show that the short-lived lakes form when an ice tunnel through a debris landform gets blocked. The blocking is caused either by the freezing of stored water inside the tunnel during winter or by the collapse of ice and debris around the ice tunnel. The draining then occurs through an opened ice tunnel during summer.

Global sea levels are rising due to climate change and this will accelerate through this century: a rise of more than 1m is possible. In some locations these changes may be exacerbated by (1) increases in storminess due to climate change, although this is less certain, and (2) human-induced subsidence due to ground fluid withdrawal from and drainage of susceptible soils, especially in deltas and alluvial plains. Sea-level rise has a range of potential impacts including higher extreme sea levels (and flooding), coastal erosion, and salinization of surface and ground waters. This threatens the loss of large areas of land and associated assets and economic activity, the displacement of millions of people, and significant coastal habitat degradation. However, adaptation can greatly reduce these impacts and promote prosperous and desirable coasts. Adaptation measures can be characterized as (1) protect, (2) accommodate, or (3) retreat approaches. The provision of information measures such as warnings is improving significantly, while novel methods such as ecosystem-based approaches are attracting interest. Adaptation to sea-level rise should be viewed as a process that requires an integrated coastal management philosophy to be consistent with wider coastal activities and other stresses. Hence, in addition to technical skills, adaptation requires an appropriate institutional capacity. The success or failure of measures of adaptation, especially protection, is contested and this influences our view of sea-level rise as a problem. Adaptation can be best analyzed in the context of understanding the coastal system that includes the effects of all drivers, including sea-level rise, their interactions, and feedbacks: these types of analyses are only just beginning. Some proactive adaptation plans are already being formulated, such as around London and in the Netherlands.

The state-of-the-art methodology to assess impacts of climate change including extreme events and uncertainties on the design and performance of energy systems is described and discussed.

However, it has not yet been adequately explored and widely used, as its definition has not been clearly articulated and assessment is mostly based on qualitative aspects. This study reveals that a major limitation in the state-of-the-art is the inadequacy of climate change adaptation approaches in designing and preparing urban energy systems to satisfactorily address plausible extreme climate events. Furthermore, the complexity of the climate and energy models and the mismatch between their temporal and spatial resolutions are the major limitations in linking these models. Therefore, few studies have focused on the design and operation of urban energy infrastructure in terms of climate resilience.

When a long‐term view genuinely is relevant to decision‐making, much of the information available is not fit for purpose.

The analysis is based on 7 climate model integrations performed with two coupled global models (ECHAM5 MPIOM and INGV CMCC), comparing the end of the twentieth century and at least the first half of the twenty-first century. As one of the models has a considerably enhanced resolution of the atmosphere and the ocean, it is also investigated whether the climate change signals are influenced by the model resolution. While the higher resolved simulation is closer to reanalysis climatology, both in terms of cyclones and windstorm distributions, there is no evidence for an influence of the resolution on the sign of the climate change signal. All model simulations show a reduction in the total number of cyclones crossing the Mediterranean region under climate change conditions. Exceptions are Morocco and the Levant region, where the models predict an increase in the number of cyclones. The reduction is especially strong for intense cyclones in terms of their Laplacian of pressure. The influence of the simulated positive shift in the NAO Index on the cyclone decrease is restricted to the Western Mediterranean region, where it explains 10–50 {\%} of the simulated trend, depending on the individual simulation. With respect to windstorms, decreases are simulated over most of the Mediterranean basin. This overall reduction is due to a decrease in the number of events associated with local cyclones, while the number of events associated with cyclones outside of the Mediterranean region slightly increases. These systems are, however, less intense in terms of their integrated severity over the Mediterranean area, as they mostly affect the fringes of the region.

Coupled climate-carbon cycle models are sensitive to this negative feedback on atmospheric CO(2), but model projections are uncertain because of the expectation that feedbacks through the nitrogen (N) cycle will reduce this so-called CO(2) fertilization effect. We assessed whether N limitation caused a reduced stimulation of net primary productivity (NPP) by elevated atmospheric CO(2) concentration over 11 y in a free-air CO(2) enrichment (FACE) experiment in a deciduous Liquidambar styraciflua (sweetgum) forest stand in Tennessee. During the first 6 y of the experiment, NPP was significantly enhanced in forest plots exposed to 550 ppm CO(2) compared with NPP in plots in current ambient CO(2), and this was a consistent and sustained response. However, the enhancement of NPP under elevated CO(2) declined from 24{\%} in 2001-2003 to 9{\%} in 2008. Global analyses that assume a sustained CO(2) fertilization effect are no longer supported by this FACE experiment. N budget analysis supports the premise that N availability was limiting to tree growth and declining over time--an expected consequence of stand development, which was exacerbated by elevated CO(2). Leaf- and stand-level observations provide mechanistic evidence that declining N availability constrained the tree response to elevated CO(2); these observations are consistent with stand-level model projections.

Dried soils and diminished vegetation cover in the Fertile Crescent, as evident through remotely sensed enhanced vegetation indices, supported greater dust generation and transport to the Arabian Peninsula in 2007?2013, as identified both in increased dust days observed at weather stations and enhanced remotely sensed aerosol optical depth. According to backward trajectory analysis of dust days on the Arabian Peninsula, increased dust lifting and atmospheric dust concentration in the Fertile Crescent during this recent, prolonged drought episode supported a greater frequency of dust events across the peninsula with associated northerly trajectories and led to the dust regime shift.

In Africa, the impact of ticks is ranked high, and they transmit diseases such as cowdriosis, anaplasmosis, bovine babesiosis and theileriosis. A range expansion of ixodid ticks has been observed in Africa, in particular for the genera Amblyomma and Rhipicephalus, which contribute greatly to cattle loss owing to morbidity and mortality. Distributional changes in ticks can lead to the emergence or re-emergence of infectious and parasitic diseases. Climate change is frequently invoked as the primary cause of tick distribution, but it is not the only factor. Human lifestyle changes, including transportation of livestock within countries, have promoted the introduction of new tick species and the diseases they transmit. One such example is the spread of the Asian cattle tick Rhipicephalus (Boophilus) microplus to West Africa. Rhipicephalus (Boophilus) microplus was recorded for the first time in Namibia and was probably introduced into Namibia from South Africa. Likewise, Amblyomma variegatum, the vector of heartwater disease, has the largest distribution in Africa. Its spread is outside its native range and it is considered the second most invasive tick species after R. (B.) microplus on the continent.

While the 46. year length of the DSI record is its greatest strength from a wind erosion monitoring perspective, there are a number of technical challenges to its use because when the World Meteorological Organisation (WMO) recording protocols were established the use of the data for wind erosion monitoring was never intended. Data recording and storage protocols are examined, including the effects of changes to the definition of how observers should interpret and record dust events. A method is described for selecting the 180 long-term ABM stations used in this study and the limitations of variable observation frequencies between stations are in part resolved. The rationale behind the DSI equation is explained and the examples of temporal and spatial data visualisation products presented include; a long term national wind erosion record (1965-2011), continental DSI maps, and maps of the erosion event types that are factored into the DSI equation. The DSI is tested against dust concentration data and found to provide an accurate representation of wind erosion activity. As the ABM observational records used here were collected according to WMO protocols, the DSI methodology could be used in all countries with WMO-compatible meteorological observation and recording systems. {\textcopyright} 2013.}, author = {O'Loingsigh, T. and McTainsh, G.

Additionally, the impact of climate forcing on WPs associated with heavy wet snowfall is evaluated to understand the spatially heterogeneous changes in wet snowfall. The SOM analysis results suggest that the future changes in spatially heterogeneous extreme wet snowfall can be attributed to differences in WP responses to climate change.

Most notably, urban heat waves for 1981–2005 are more intense than grid cell-average by 2.1 °C (southeast) to 4.6 °C (southwest), while cold waves are less intense. We assess the avoided climate impacts of urban heat/cold waves in 2061–2080 when following the lower forcing scenario. Urban heat wave days per year increase from 6 in 1981–2005 to up to 92 (southeast) in RCP8.5. Following RCP4.5 reduces heat wave days by about 50 {\%}. Large avoided impacts are demonstrated for individual communities; e.g., the longest heat wave for Houston in RCP4.5 is 38 days while in RCP8.5 there is one heat wave per year that is longer than a month with some lasting the entire summer. Heat waves also start later in the season in RCP4.5 (earliest are in early May) than RCP8.5 (mid-April), compared to 1981–2005 (late May). In some communities, cold wave events decrease from 2 per year for 1981–2005 to one-in-five year events in RCP4.5 and one-in-ten year events in RCP8.5.}, author = {Oleson, K. W. and Anderson, G.

This paper combines UKCP09 Weather Generator predictions with a probabilistic process to create hourly time series of climate parameters under a high-emissions scenario for 2070–2099 at eight UK sites. Exposure to WDR at these sites for baseline and future periods is calculated from semi-empirical models based on long-term hourly meteorological data using ISO 15927-3:2009. Towards the end of the twenty-first century, it is predicted that rain spells will have higher volumes, i.e. a higher quantity of water will impact fa{\c{c}}ades, across all 8 sites. Although the average number of spells is predicted to remain constant, they will be shorter with longer of periods of time between them and more intense with wind-driven rain occurring for a greater proportion of hours within them. It is likely that in this scenario building element failure – such as moisture ingress through cracks and gutter over-spill – will occur more frequently. There will be higher rates of moisture cycling and enhanced deep-seated wetting.

The purpose of the review is to evaluate the recent evidence on the impacts of climate change on air pollution and air pollution-related health impacts and identify knowledge gaps for future research. Recent Findings: Several studies modelled future ozone and particulate matter concentrations and calculated the resulting health impacts under different climate scenarios. Due to climate change, ozone- and fine particle-related mortalities are expected to increase in most studies; however, results differ by region, assumed climate change scenario and other factors such as population and background emissions. Summary: This review explores the relationships between climate change, air pollution and air pollution-related health impacts.

As the climate model outputs for Poland are highly biased, post processing in the form of bias correction was first performed so that the climate time series could be applied in hydrological simulations at a catchment-scale. The results indicate that bias correction significantly improves flow simulations and estimated flood indices based on comparisons with simulations from observed climate data for the control period. The estimated changes in the mean annual flood and in flood quantiles under a future climate indicate a large spread in the estimates both within and between the catchments. An ANOVA analysis was used to assess the relative contributions of the 2 emission scenarios, the 7 climate models and the 4 bias correction methods to the total spread in the projected changes in extreme river flow indices for each catchment. The analysis indicates that the differences between climate models generally make the largest contribution to the spread in the ensemble of the three factors considered.

The first approach focuses on their rate of intensification, whereas the second approach implicitly focuses on their duration. These conflicting notions for what constitutes a flash drought (i.e., unusually fast intensification vs short duration) introduce ambiguity that affects our ability to detect their onset, monitor their development, and understand the mechanisms that control their evolution.

ROS events occur mainly in high-latitude and mountainous areas, where sparse observational networks hinder accurate quantification—as does a scale mismatch between coarse-resolution (50–100 km) reanalysis products and localized events. Variability in the rain–snow temperature threshold and temperature sensitivity of snowmelt adds additional uncertainty. Here the high-resolution (1 km) seNorge hydrometeorological dataset, capturing complex topography and drainage networks, is utilized to produce the first large-scale climatology of ROS events for mainland Norway. For daily data spanning 1957–2016, suitable rain and snowpack thresholds for defining ROS events are applied to construct ROS climatologies for 1961–90 and 1981–2010 and to investigate trends. Differing ROS characteristics are found, reflecting Norway's diverse climates. Relative to 1961–90, events in the 1981–2010 period decrease most in the southwest low elevations in winter, southeast in spring, and north in summer (consistent with less snow cover in a warming climate) and increase most in the southwest high elevations, central mountains, and north in winter–spring (consistent with increased precipitation and/or more snow falling as rain in a warming climate). Winter–spring events also broadly correlate with the North Atlantic Oscillation, and the Scandinavia pattern—and more so with the Arctic Oscillation, particularly in the southern mountain region where long-term ROS trends are significant (10.50 and 10.33 daily ROS counts per kilometer squared per decade for winter and spring).}, author = {Pall, Pardeep and Tallaksen, Lena M. and Stordal, Frode}, doi = {10.1175/JCLI-D-18-0529.1}, issn = {08948755}, journal = {Journal of Climate}, month = {oct}, number = {20}, pages = {6995--7016}, publisher = {American Meteorological Society}, title = {{A climatology of rain-on-snow events for Norway}}, volume = {32}, year = {2019} } @article{Panthou2014a, abstract = {AbstractRecent studies have examined the relationship between the intensity of extreme rainfall and temperature.

The relationship between extreme rainfall intensity and air temperature (Pextr–Ta) was assessed by analyzing maximum daily rainfall intensities for durations ranging from 5 min to 12 h for more than 100 meteorological stations across Canada.

We used local climate records to compare outbreak-climate relationships in the northern Patagonian Andes (c. 41 degrees S) and the cooler southern Patagonian Andes (c. 49 degrees S). We also examined relationships between outbreak events and regional climate variability driven by variability in the Southern Annular Mode (SAM) and the El Nino-Southern Oscillation. Although relationships between Ormiscodes outbreaks and climate proved to be complex, in northern Patagonia defoliation events are associated with drier and warmer than average growing seasons. Warming and drying trends in Patagonia during the latter part of the 20th century have been linked to a positive trend in SAM. During the post-1976 period of accelerated warming in Patagonia, widespread defoliation outbreaks have occurred in both northern and southern Patagonia but the increase in frequency of events has been greater in the south. In southern Patagonia the increases in frequency of outbreaks in the late 20th century appear to be unprecedented over the c. 150 year tree-ring record of reconstructed outbreaks. These results are consistent with the greater magnitude of recent warming in southern Patagonia, and suggest that under predicted warmer and drier climates in the 21st century, defoliator outbreaks may continue to increase in frequency.

Correspondence between the FDSI and measures of forest productivity, mortality, bark-beetle outbreak and wildfire validate the FDSI as a holistic forest-vigour indicator.

We synthesize the available literature to address five questions of practical importance, which can be used to evaluate fundamental knowledge of landslide process and inform land management decisions to mitigate geohazards and environmental impacts. After permafrost thaws, we predict that landslides will be driven primarily by atmospheric input of moisture and freeze-thaw fracturing rather than responding to disconnected and perched groundwater, melting permafrost ice, and a plane of weakness between ground ice and the active layer. Transition between equilibrium states is likely to increase landslide frequency and magnitude, alter dominant failure styles, and mobilize carbon over timescales ranging from seasons to centuries.

Here, we used analyses at national and state scales to examine a suite of climatic and intrinsic drivers of continental-scale West Nile virus epidemics, including an empirically derived mechanistic relationship between temperature and transmission potential that accounts for spatial variability in vectors. We found that drought was the primary climatic driver of increased West Nile virus epidemics, rather than within-season or winter temperatures, or precipitation independently. Local-scale data from one region suggested drought increased epidemics via changes in mosquito infection prevalence rather than mosquito abundance.

Some crops (e.g. winter wheat) responded to drought at medium to long SPEI time-scales, while other crops (e.g. soybean and corn) responded to short or long drought time-scales. The study confirms that the differences in the patterns of crop yield response to drought time-scales are mostly controlled by average climate conditions, in general, and water availability (precipitation), in particular. Generally, we found that there is a weaker link between crop yield and drought severity in humid environments and also that the response tends to occur over longer time-scales.}, author = {Pe{\~{n}}a-Gallardo, Marina and Vicente-Serrano, Sergio M. and Quiring, Steven and Svoboda, Marc and Hannaford, Jamie and Tomas-Burguera, Miquel and Mart{\'{i}}n-Hern{\'{a}}ndez, Natalia and Dom{\'{i}}nguez-Castro, Fernando and {El Kenawy}, Ahmed}, doi = {10.1016/j.agrformet.2018.09.019}, issn = {01681923}, journal = {Agricultural and Forest Meteorology}, keywords = {Climatic change,Crop yields,Cultivations,Drought impacts,Drought index,Natural hazards,SPEI}, month = {jan}, pages = {40--55}, publisher = {Elsevier B.V.}, title = {{Response of crop yield to different time-scales of drought in the United States: Spatio-temporal patterns and climatic and environmental drivers}}, volume = {264}, year = {2019} } @article{Pearce2015, abstract = {[This paper examines the role of Inuit traditional ecological knowledge (TEK) in adaptation to climate change in the Canadian Arctic. It focuses on Inuit relationships with the Arctic environment, including hunting knowledge and land skills, and examines their roles in adaptation to biophysical changes that affect subsistence hunting. In several instances, TEK underpins competency in subsistence and adaptations to changing conditions, which inculdes flexibility with regard to seasonal cycles of hunting and resource use, hazard avoidance through detailed knowledge of the environment and understanding of ecosystem processes, and emergency preparedness, e.g., knowing what supplies to take when traveling and how to respond in emergency situations. Despite the documented importance of TEK in adaptation and in maintaining a level of competency in subsistence, the relationships between TEK and adaptation to climate change are not well defined in the scholarly literature. This paper aims to conceptualize the relationships between TEK and adaptation to climate change by drawing on case study research with Inuit in the Canadian Arctic. TEK is considered an element of adaptive capacity (or resilience) that is expressed as adaptation if TEK is drawn upon to adapt to changing conditions. This capacity depends on the development, accumulation, and transmission of TEK within and among generations.

Warming has been associated with population declines in long-distance migrants and habitat specialists, and increases in southerly distributed species. However, the specific climatic drivers behind these changes remain undescribed. We analysed annual fluctuations in the abundance of 59 breeding bird species in England over 45 years to test the effect of monthly temperature and precipitation means upon population trends. Strong positive correlations between population growth and both winter and breeding season temperature were identified for resident and short-distance migrants. Lagged correlations between population growth and summer temperature and precipitation identified for the first time a widespread negative impact of hot, dry summer weather. Resident populations appeared to increase following wet autumns. Populations of long-distance migrants were negatively affected by May temperature, consistent with a potential negative effect of phenological mismatch upon breeding success. There was evidence for some nonlinear relationships between monthly weather variables and population growth. Habitat specialists and cold-associated species showed consistently more negative effects of higher temperatures than habitat generalists and southerly distributed species associated with warm temperatures. Results suggest that previously reported changes in community composition represent the accumulated effects of spring and summer warming. Long-term population trends were more significantly correlated with species? sensitivity to temperature than precipitation, suggesting that warming has had a greater impact on population trends than changes in precipitation. Months where there had been the greatest warming were the most influential drivers of long-term change. There was also evidence that species with the greatest sensitivity to extremes of precipitation have tended to decline. Our results provide novel insights about the impact of climate change on bird communities. Significant lagged effects highlight the potential for altered species? interactions to drive observed climate change impacts, although some community changes may have been driven by more immediate responses to warming. In England, resident and short-distance migrant populations have increased in response to climate change, but potentially at the expense of long-distance migrants,{\ldots}}, author = {Pearce-Higgins, James W and Eglington, Sarah M and Martay, Blaise and Chamberlain, Dan E}, doi = {10.1111/1365-2656.12364}, issn = {0021-8790}, journal = {Journal of Animal Ecology}, month = {mar}, number = {4}, pages = {943--954}, publisher = {Wiley/Blackwell (10.1111)}, title = {{Drivers of climate change impacts on bird communities}}, volume = {84}, year = {2015} } @article{Pederson2013a, annote = {Cited By :32 Export Date: 24 July 2018}, author = {Pederson, N and Leland, C and Nachin, B and Hessl, A E and Bell, A R and Martin-Benito, D and Saladyga, T and Suran, B and Brown, P M and Davi, N K}, doi = {10.1016/j.agrformet.2012.07.003}, journal = {Agricultural and Forest Meteorology}, pages = {10--20}, title = {{Three centuries of shifting hydroclimatic regimes across the Mongolian Breadbasket}}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84880334072{\&}doi=10.1016{\%}2Fj.agrformet.2012.07.003{\&}partnerID=40{\&}md5=4cadbc767a22f23a567da0af358efd04}, volume = {178-179}, year = {2013} } @article{Pederson2011, author = {Pederson, Gregory T. and Gray, Stephen T. and Woodhouse, Connie A. and Betancourt, Julio L. and Fagre, Daniel B. and Littell, Jeremy S. and Watson, Emma and Luckman, Brian H. and Graumlich, Lisa J.}, doi = {10.1126/science.1201570}, issn = {0036-8075}, journal = {Science}, month = {jul}, number = {6040}, pages = {332--335}, title = {{The Unusual Nature of Recent Snowpack Declines in the North American Cordillera}}, url = {http://www.sciencemag.org/lookup/doi/10.1126/science.1201570}, volume = {333}, year = {2011} } @article{Pedro-Monzonis2015, author = {Pedro-Monzon{\'{i}}s, Mar{\'{i}}a and Solera, Abel and Ferrer, Javier and Estrela, Teodoro and Paredes-Arquiola, Javier}, doi = {10.1016/j.jhydrol.2015.05.003}, issn = {00221694}, journal = {Journal of Hydrology}, month = {aug}, pages = {482--493}, title = {{A review of water scarcity and drought indexes in water resources planning and management}}, url = {http://linkinghub.elsevier.com/retrieve/pii/S0022169415003388}, volume = {527}, year = {2015} } @article{Peel2013, author = {Peel, Jennifer L. and Haeuber, Richard and Garcia, Valerie and Russell, Armistead G. and Neas, Lucas}, doi = {10.1007/s10533-012-9782-4}, issn = {0168-2563}, journal = {Biogeochemistry}, month = {jul}, number = {1-3}, pages = {121--134}, title = {{Impact of nitrogen and climate change interactions on ambient air pollution and human health}}, url = {http://link.springer.com/10.1007/s10533-012-9782-4}, volume = {114}, year = {2013} } @article{Peeters2019a, abstract = {Arctic winters have become increasingly warmer and rainier. Where permafrost prevails, winter rain (or rain-on-snow) is known to occasionally cause extensive ice layers at the snow/ground interface, i.e. 'basal ice' or 'ground ice', with potentially large ecological and socio-economic implications. However, an overall lack of field data has so far restricted our predictive understanding of the environmental conditions shaping spatiotemporal variation in basal ice. Here, we use time-series of spatially replicated snowpack measurements from coastal (Ny-{\AA}lesund area; 2000-2017) and central Spitsbergen (Nordenski{\"{o}}ld Land; 2010-2017), Svalbard, to analyze spatiotemporal patterns in basal ice and how they are linked with topography, weather, snowpack and climate change. As expected, both the spatial occurrence and thickness of basal ice increased strongly with the annual amount of winter rain. This effect was modified by accumulated snowfall; a deeper snowpack restricts ice formation following a minor rain event, but enhances ice formation following heavy rain due to an increased contribution of snowmelt. Accordingly, inter-annual variation in snow depth was negatively related to basal ice thickness. Annual fluctuations in basal ice thickness were strongly correlated in space (average correlation $\rho$ = 0.40; 0-142 km distance between plots) due to strong spatial correlation in winter rain ($\rho$ = 0.62; 14-410 km distance between meteorological stations). Models of basal ice based on meteorological time-series (1957-2017) suggested that ice-free winters (i.e. mean basal ice {\textless}0.1 cm) had virtually not occurred since 1998, whereas such winters previously (1957-1998) occurred every three-four years on average. This detected cryosphere regime shift was linked to a parallel climate regime shift with increased winter rain amounts. Svalbard is regarded a bellwether for Arctic winter climate change.

This asymmetric warming is expected to affect carbon assimilation and consumption in plants, because photosynthesis in most plants occurs during daytime and is more sensitive to the maximum daily temperature, Tmax, whereas plant respiration occurs throughout the day and is therefore influenced by both T max and the minimum daily temperature, Tmin. Most studies of the response of terrestrial ecosystems to climate warming, however, ignore this asymmetric forcing effect on vegetation growth and carbon dioxide (CO 2) fluxes. Here we analyse the interannual covariations of the satellite-derived normalized difference vegetation index (NDVI, an indicator of vegetation greenness) with Tmax and Tmin over the Northern Hemisphere. After removing the correlation between Tmax and T min, we find that the partial correlation between Tmax and NDVI is positive in most wet and cool ecosystems over boreal regions, but negative in dry temperate regions. In contrast, the partial correlation between Tmin and NDVI is negative in boreal regions, and exhibits a more complex behaviour in dry temperate regions. We detect similar patterns in terrestrial net CO2 exchange maps obtained from a global atmospheric inversion model. Additional analysis of the long-term atmospheric CO2 concentration record of the station Point Barrow in Alaska suggests that the peak-to-peak amplitude of CO2 increased by 23 ± 11{\%} for a +1°C anomaly in T max from May to September over lands north of 51N, but decreased by 28 ± 14{\%} for a +1°C anomaly in Tmin. These lines of evidence suggest that asymmetric diurnal warming, a process that is currently not taken into account in many global carbon cycle models, leads to a divergent response of Northern Hemisphere vegetation growth and carbon sequestration to rising temperatures. {\textcopyright} 2013 Macmillan Publishers Limited.

Detailed knowledge of ALT variations is also important for studies on ecosystem, hydrological, and geomorphological processes in cold regions. The primary objective of this study is therefore to provide a comprehensive 1971-2000 climatology of ALT and its changes across the entire Northern Hemisphere from 1850 through 2100. To accomplish this, in situ observations, the Stefan solution based on a thawing index, and the edaphic factor (E factor) are employed to calculate ALT. The thawing index is derived from (i) the multimodel ensemble mean of 16 models from phase 5 of the Coupled Model Intercomparison Project (CMIP5) over 1850-2005, (ii) three representative concentration pathways (RCP2.6, RCP4.5, and RCP8.5) for 2006-2100, and (iii) Climatic Research Unit (CRU) gridded observations for 1901-2014. The results show significant spatial variability in in situ ALT that generally ranges from 40 to 320 cm, with some extreme values of 900 cm in the Alps. The differences in the ALT climatology between the three RCPs and the historical experiments ranged from 0 to 200 cm. The biggest increases, of 120-200 cm, are on the Qinghai-Tibetan Plateau, while the smallest increases of less than 20 cm are in Alaska.

However, weather stations on the Tibetan plateau are mostly located at lower elevations (3,000-4,000 m) and are nonexistent above 5,000 m, leaving critical temperature changes unknown. Satellite LST (Land Surface Temperature) can fill this gap but needs calibrating against in situ air temperatures (Tair). We develop a novel statistical model to convert LST to Tair, developed at 87 high-elevation Chinese Meteorological Administration stations. Tair (daily maximum/minimum temperatures) is compared with Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua LST (1330 and 0130 local time) for 8-day composites during 2002-2017. Typically, 80-95{\%} of the difference between LST and Tair (?T) is explained using predictors including LST diurnal range, morning heating/nighttime cooling rates, the number of cloud free days/nights, and season (solar angle). LST is corrected to more closely represent Tair by subtracting modeled ?T. We validate the model using an AWS on Zhadang Glacier (5800 m). Trend analysis at the 87 stations (2002-2017) shows corrected LST trends to be similar to original Tair trends. To examine regional contrasts in EDW patterns, elevation profiles of corrected LST trends are derived for three ranges (Qilian Mountains, NyenchenTanglha, and Himalaya). There is limited EDW in the Qilian mountains. Maximum warming is observed around 4,500-5,500 m in NyenchenTanglha, consistent with snowline retreat.

In this paper we provide a methodology for estimating return period of landslide triggering under climate change. The methodology capitalizes on the combined use of a stochastic rainfall generator and a hydrological and slope stability model. The stochastic rainfall generator takes into account the statistical dependency between rainfall event duration and intensity through copulas. The hydrological model is based on an analytical solution of a simplified version of the Richards vertical infiltration equation and slope stability is assessed by the infinite slope model. The combined model enables to estimate landslide probability through Monte Carlo simulations. Climate change is then introduced by perturbing the parameters of the rainfall stochastic generator based on factors of change derived from the comparison of future scenarios and the baseline climate as simulated by Regional climate models (RCMs). The Monte Carlo simulations are conducted sequentially on a future moving time window, to derive a yearly series of future landslide triggering probability. This series is then used to compute landslide return period by formulas suitable under nonstationary conditions. An application to the landslide prone region of the Peloritani Mountains, Southern Italy, is carried out to demonstrate the proposed approach. For the application, climate change projections of three RCMs of the MED-CORDEX initiative are used, and a preliminary assessment of the impacts of intermediate- and high-emission Representative concentration pathways (RCPs) 4.5 and 8.5 is carried out.}, author = {Peres, D.

Like many such events, the 2012 marine heatwave in the Gulf of Maine revealed unexpected connections within the ecosystem and between the natural and human components of the system. The strongest economic impacts were to Maine's valuable lobster fishery. In 2012, early and intense landings led to a backlog in the supply chain and a drop in price. This experience prompted the lobster industry to implement changes throughout the supply chain to avoid the severe drop in price should another warm year with early landings occur. Here we describe a second heatwave in the Gulf of Maine that occurred in 2016. Despite a similar pattern in monthly landings, dockside prices for lobster were higher than expected. The contrast with 2012 suggests that the adaptations in the supply chain were successful. The 2012 and 2016 heatwaves are part of a broader pattern of temperature changes in this region. Warmer autumns allow sea turtles to remain in the Gulf of Maine longer, increasing their risk of being stunned or killed by cold water, and warm years followed by cold years typically lead to a decline in lobster landings. While there is evidence for adaptation to rising temperatures in the Gulf of Maine, the adaptation brought a significant shock to the system. Forecasts may help foster adaptation while avoiding shocks, but this will require a substantial shift in the mindsets of both forecast producers and consumers.}, author = {Pershing, Andrew and Mills, Katherine and Dayton, Alexa and Franklin, Bradley and Kennedy, Brian}, doi = {10.5670/oceanog.2018.213}, issn = {10428275}, journal = {Oceanography}, number = {2}, pages = {152--161}, publisher = {JSTOR}, title = {{Evidence for Adaptation from the 2016 Marine Heatwave in the Northwest Atlantic Ocean}}, url = {https://tos.org/oceanography/article/evidence-for-adaptation-from-the-2016-marine-heatwave-in-the-northwest-atl}, volume = {31}, year = {2018} } @article{Pes2017, abstract = {The main source of electricity in Brazil is from hydro, which has about 65.2{\%} share of the country's electric energy matrix.

Since wind is an intermittent energy source, heavily determined by the weather and climatic conditions, and important effects on wind power generation can be expected in the mid and long term, in particular related to the impacts of extreme winds. The IPCC AR5 (Intergovernmental Panel on Climate Change) indicates changes in wind speed at the surface in some regions of the world, and increased wind strength in mid-latitude regions. This study scrutinizes future scenarios of extreme winds in Brazil by applying trend analysis techniques on a 50-year historical series of observational wind speed and meteorological parameters at 10 m height in Brazil. Embracing techniques of cluster analysis it was possible to characterize six main regions with macro climatic similarities. To assess the goodness fit distribution, we designate two stations per homogenous region, taking as criteria the stations with better performance in the qualification process to determine the wind distribution pattern in each region applying the Kolmogorov-Smirnov test (KS) and the lowest standard error (SE). After evaluating the frequency distribution of wind speed, the best fit result for the frequency distribution of maximum wind speed is the Gumbel model. The analysis of climatic trends performed by Mann-Kendall test revealed that in minimum wind speed series is not conclusive because it shows disparate results between homogeneous regions. On the other hand, the analysis of climatic trends of maximum wind speed presents 100{\%} positive trends in Group{\#}1, an equal number of stations with not significant trends and positive trends for Group{\#}2, 36.8{\%} more stations with positive trends than negative trends for Group{\#}3 and 20{\%} of stations with more negative trends than stations with positive trends for Group{\#}4.

Apart from reducing the milk production, heat stress can also reduce the quality of milk. Internal metabolic heat production during lactation can further reduce the resistance of cattle to high ambient temperature, resulting in altered milk composition and reduction in milk yield. Heat stress can affect the various components of milk such as fat ({\%}), solid-non-fat, protein, casein and lactose content. Heat stress can increase the somatic cell count indicating the reduction in quality of milk produced. Further, heat stress can also cause endocrine disbalance such as altering the levels of prolactin, thyroid hormones, glucocorticoid, growth hormone, estrogen, progesterone and oxytocin which ultimately affects the milk production. Heat stress through higher udder temperature may also cause mastitis in dairy cows. In addition, heat stress during dry period in particular might trigger mammary gland involution accompanied with apoptosis and autophagy, decreased amount of mammary epithelial cells can ultimately cause decline in milk yield.

Therefore, pairs of fine- and coarse-gridded simulations of eight reanalysis-driven models are compared to fine-gridded observations in the Alps, Germany, Sweden, Norway, France, the Carpathians, and Spain. A clear result is that the 0.11∘simulations are found to better reproduce mean and extreme precipitation for almost all regions and seasons, even on the scale of the coarser-gridded simulations (50 km). This is primarily caused by the improved representation of orography in the 0.11∘simulations and therefore largest improvements can be found in regions with substantial orographic features. Improvements in reproducing precipitation in the summer season appear also due to the fact that in the fine-gridded simulations the larger scales of convection are captured by the resolved-scale dynamics.

Here we present a statistical approach that estimates hail hazard from large-scale environmental conditions. Using daily ERA-Interim reanalysis data and large hail observations (diameter larger than 2.5 cm) from the conterminous United States (CONUS) we show that four predictors enable skillful discrimination of large hail frequencies on a regional scale. The predictors include atmospheric instability, freezing level height, and 0–3 km wind shear and storm relative helicity. These variables are used to develop a hail algorithm, which provides the probabilities for large hail occurrence from regional to global scales and from daily to climate timescales. The algorithm skill is tested over the CONUS and with independent hail observations from Australia and Europe. It skillfully captures the frequency, annual cycle, spatial patterns, and interannual variability of observed large hail records in a large variety of climate regions. Deficiencies are found in regions with strong orographic forcing and low shear environments. The algorithm outperforms established severe convection indices in terms of more accurately predicting absolute hail frequencies and the annual cycles of large hail in all tested regions.

Although solar radiation management may increase crop yields by reducing heat stress4, the effects of concomitant changes in available sunlight have never been empirically estimated. Here we use the volcanic eruptions that inspired modern solar radiation management proposals as natural experiments to provide the first estimates, to our knowledge, of how the stratospheric sulfate aerosols created by the eruptions of El Chich{\'{o}}n and Mount Pinatubo altered the quantity and quality of global sunlight, and how these changes in sunlight affected global crop yields. We find that the sunlight-mediated effect of stratospheric sulfate aerosols on yields is negative for both C4 (maize) and C3 (soy, rice and wheat) crops. Applying our yield model to a solar radiation management scenario based on stratospheric sulfate aerosols, we find that projected mid-twenty-first century damages due to scattering sunlight caused by solar radiation management are roughly equal in magnitude to benefits from cooling. This suggests that solar radiation management—if deployed using stratospheric sulfate aerosols similar to those emitted by the volcanic eruptions it seeks to mimic—would, on net, attenuate little of the global agricultural damage from climate change.

The impact on drought is uncertain because of the complexity of the processes but can be estimated using outputs from an ensemble of global models (hydrological and climate models). Using an ensemble of 35 simulations, we show a likely increase in the global severity of drought by the end of 21st century, with regional hotspots including South America and Central and Western Europe in which the frequency of drought increases by more than 20{\%}. The main source of uncertainty in the results comes from the hydrological models, with climate models contributing to a substantial but smaller amount of uncertainty.Increasing concentrations of greenhouse gases in the atmosphere are expected to modify the global water cycle with significant consequences for terrestrial hydrology. We assess the impact of climate change on hydrological droughts in a multimodel experiment including seven global impact models (GIMs) driven by bias-corrected climate from five global climate models under four representative concentration pathways (RCPs). Drought severity is defined as the fraction of land under drought conditions. Results show a likely increase in the global severity of hydrological drought at the end of the 21st century, with systematically greater increases for RCPs describing stronger radiative forcings. Under RCP8.5, droughts exceeding 40{\%} of analyzed land area are projected by nearly half of the simulations. This increase in drought severity has a strong signal-to-noise ratio at the global scale, and Southern Europe, the Middle East, the Southeast United States, Chile, and South West Australia are identified as possible hotspots for future water security issues. The uncertainty due to GIMs is greater than that from global climate models, particularly if including a GIM that accounts for the dynamic response of plants to CO2 and climate, as this model simulates little or no increase in drought frequency. Our study demonstrates that different representations of terrestrial water-cycle processes in GIMs are responsible for a much larger uncertainty in the response of hydrological drought to climate change than previously thought. When assessing the impact of climate change on hydrology, it is therefore critical to consider a diverse range of GIMs to better capture the uncertainty.}, author = {Prudhomme, Christel and Giuntoli, Ignazio and Robinson, Emma L. and Clark, Douglas B. and Arnell, Nigel W. and Dankers, Rutger and Fekete, Bal{\'{a}}zs M. and Franssen, Wietse and Gerten, Dieter and Gosling, Simon N. and Hagemann, Stefan and Hannah, David M. and Kim, Hyungjun and Masaki, Yoshimitsu and Satoh, Yusuke and Stacke, Tobias and Wada, Yoshihide and Wisser, Dominik}, doi = {10.1073/pnas.1222473110}, file = {::}, issn = {0027-8424}, journal = {Proceedings of the National Academy of Sciences}, month = {mar}, number = {9}, pages = {3262--3267}, title = {{Hydrological droughts in the 21st century, hotspots and uncertainties from a global multimodel ensemble experiment}}, url = {http://www.pnas.org/content/111/9/3262.abstract}, volume = {111}, year = {2014} } @article{Pu2017, abstract = {Climate models project rising drought risks over the southwestern and central U.S. in the twenty-first century due to increasing greenhouse gases.

The RegCM4 has projected an increase in the mean seasonal precipitation by 0.56 mm/day whereas in case of GFDL model the rate is 0.39 mm/day during the far-future relative to the reference period. The heavy precipitation indices are projected to increase more frequently (0.264/decade) than the mean precipitation rate (0.01/decade) over India. The correlations between the extreme precipitation indices and the seasonal mean precipitation are found to be strong. In addition, the consecutive dry days are projected to occur more frequently (3–5 days) over West Central (Telangana, Vidarbha and Marathwada) and west Rajasthan while consecutive wet days are projected to decrease over larger parts of India during far-future. Similarly, 1 day maximum precipitation and the simple daily intensity index are projected to increase consistently from mid- to far- futures over some sub-divisions of West coast, Hilly and Northeast regions. From a spatial probability perspective, model projection indicates more frequent severe drought and flood conditions over India.}, author = {Rai, P K and Singh, G P and Dash, S K}, doi = {10.1007/s00382-019-04997-6}, issn = {1432-0894}, journal = {Climate Dynamics}, number = {1}, pages = {247--272}, title = {{Projected changes in extreme precipitation events over various subdivisions of India using RegCM4}}, url = {https://doi.org/10.1007/s00382-019-04997-6}, volume = {54}, year = {2020} } @article{Rajczak2017, author = {Rajczak, Jan and Sch{\"{a}}r, Christoph}, doi = {10.1002/2017JD027176}, issn = {2169897X}, journal = {Journal of Geophysical Research: Atmospheres}, keywords = {EURO‐CORDEX,Europe,Regional Climate Models,climate projections,extremes,precipitation}, month = {oct}, number = {20}, pages = {10773--10800}, publisher = {Wiley-Blackwell}, title = {{Projections of Future Precipitation Extremes Over Europe: A Multimodel Assessment of Climate Simulations}}, url = {http://doi.wiley.com/10.1002/2017JD027176}, volume = {122}, year = {2017} } @article{Ramarao2019, abstract = {In this study, a quantitative assessment of observed aridity variations over the semiarid regions of India is performed for the period 1951–2005 using a dimensionless ratio of annual precipitation (P) and potential evapotranspiration (PET), estimated from five different observed gridded precipitation data sets. The climatological values and changes of this aridity index are found to be sensitive to the choice of the precipitation observations. An assessment of P/PET estimated using the ensemble mean precipitation shows an increase in aridity over several semiarid regions of India, despite the sensitivity of P/PET variations across individual precipitation data sets.

But how does the effect of climate change on fluvial sediment loads compare with that of human impacts?

Alternative sources of water, such as more resilient permafrost features (e.g. rock glaciers), are expected to become increasingly important as current warming continues. Assessments of current and future permafrost extent under climate change are not available for the Southern Hemisphere, yet are required to inform decision making over future water supply and climate change adaptation strategies. Here, downscaled model outputs were used to calculate the projected changes in permafrost extent for a first-order assessment of an example region, the Bolivian Andes. Using the 0 °C mean annual air temperature as a proxy for permafrost extent, these projections show that permafrost areas will shrink from present day extent by up to 95 {\%} under warming projected for the 2050s and by 99 {\%} for the 2080s (under the IPCC A1B scenario, given equilibrium conditions). Using active rock glaciers as a proxy for the lower limit of permafrost extent, we also estimate that projected temperature changes would drive a near total loss of currently active rock glaciers in this region by the end of the century. In conjunction with glacier recession, a loss of permafrost extent of this magnitude represents a water security problem for the latter part of the 21st century, and it is likely that this will have negative effects on one of South America's fastest growing cities (La Paz), with similar implications for other arid mountain regions.}, author = {Rangecroft, Sally and Suggitt, Andrew J. and Anderson, Karen and Harrison, Stephan}, doi = {10.1007/s10584-016-1655-8}, issn = {15731480}, journal = {Climatic Change}, month = {jul}, number = {1-2}, pages = {231--243}, publisher = {Springer Netherlands}, title = {{Future climate warming and changes to mountain permafrost in the Bolivian Andes}}, volume = {137}, year = {2016} } @article{Rasoulkhani2020, abstract = {Coastal water supply infrastructure systems are exposed to saltwater intrusion exacerbated by sea-level rise stressors.

These accretion processes respond to changes in local and global forcings, such as sediment delivery to the coast, nutrient concentrations, and atmospheric CO2, but their relative importance for marsh resilience to increasing RRSLR remains unclear. In particular, marshes up-take atmospheric CO2 at high rates, thereby playing a major role in the global carbon cycle, but the morphologic expression of increasing atmospheric CO2 concentration, an imminent aspect of climate change, has not yet been isolated and quantified. Using the available observational literature and a spatially explicit ecomorphodynamic model, we explore marsh responses to increased atmospheric CO2, relative to changes in inorganic sediment availability and elevated nitrogen levels. We find that marsh vegetation response to foreseen elevated atmospheric CO2 is similar in magnitude to the response induced by a varying inorganic sediment concentration, and that it increases the threshold RRSLR initiating marsh submergence by up to 60{\%} in the range of forcings explored. Furthermore, we find that marsh responses are inherently spatially dependent, and cannot be adequately captured through 0-dimensional representations of marsh dynamics.

For present climate, there is good agreement among reanalyses and models in associating austral winter and summer with higher and lower cyclone frequency, respectively. In addition, the simulations present the mean features of the cyclones (lifetime, distance travelled and mean velocity) as similar to those of the reanalysis. Moreover, RegCM4 outperforms the HadGEM2?ES by simulating more realistically the spatial pattern of the cyclogenesis density over the SAO, which indicates value added from the RegCM4 downscaling.

Solar radiation, especially photosynthetically active radiation (PAR), is the main energy source of plant photosynthesis, and the diffuse component can enhance canopy light use efficiency, thus increasing ecosystem productivity. In order to predict the terrestrial ecosystem productivity precisely, we not only need global radiation and PAR as driving variables, but also need to treat diffuse radiation and diffuse PAR explicitly in ecosystem models.

The health of ocean ecosystems depends on whether basic biotic functions are maintained, ecosystem engineers and keystone species are retained, and the spread of nuisance species is avoided2. Here, we show in a field experiment that the toxic microalga Vicicitus globosus has a selective advantage under ocean acidification, increasing its abundance in natural plankton communities at CO2 levels higher than 600 µatm and developing blooms above 800 µatm CO2. The mass development of V. globosus has had a dramatic impact on the plankton community, preventing the development of the micro- and mesozooplankton communities, thereby disrupting trophic transfer of primary produced organic matter. This has prolonged the residence of particulate matter in the water column and caused a strong decline in export flux. Considering its wide geographical distribution and confirmed role in fish kills3, the proliferation of V. globosus under the IPCC4 CO2 emission representative concentration pathway (RCP4.5 to RCP8.5) scenarios may pose an emergent threat to coastal communities, aquaculture and fisheries.

Partly to address this drawback, the climate change research community has developed a new scenario framework, made up of distinct sets of climate and socioeconomic scenarios. The few assessments of future heat-related health risk that have employed this new framework have focused on changes in population exposure but have often not accounted for future populations' vulnerability. In this paper, we combine European Shared Socioeconomic Pathways with Representative Concentration Pathways to provide spatially explicit European projections of heat-related health risk that account for multiple changes in both socioeconomic and climatic conditions. In doing so, we also address the challenge of accounting for projections of determinants of vulnerability under varying levels of socioeconomic development. Results reveal that the proportion of the European population at very high risk of heat stress will show a steady increase – from 0.4{\%} currently to 20.3{\%}, 32.6{\%}, or 48.4{\%} in 2050 depending on the scenario combination – unless substantial political changes occur rapidly and steadily shift the current socioeconomic development pathway towards sustainability. Ambitious mitigation policies associated with rapid technological progress to enhance human capital could also moderate future heat-related health challenges. Such challenges are unevenly spread across Europe, with the Mediterranean region and Scandinavia being respectively the most and the least impacted regions. Future heat-related health challenges are substantially influenced by varying levels of socioeconomic development, primarily through changes in vulnerability – changes in population exposure being only of secondary importance. The former may even have a more significant impact on future heat stress risk than climate change, particularly in the British Isles and in the Iberian Peninsula.

Results show large discrepancies in the magnitude of change in Q100among the hydrological simulations for different climate experiments, with some regions even showing an opposite signal of change.

However, only a few regions around the world are currently undergoing precipitation changes that can be attributed to climate change. Knowing when such changes are projected to emerge outside natural variability—the time of emergence (TOE)—is critical for taking effective adaptation measures. Using ensemble climate projections, we determine the TOE of regional precipitation changes globally and in particular for the growing areas of four major crops. We find relatively early ({\textless}2040) emergence of precipitation trends for all four crops. Reduced (increased) precipitation trends encompass 1–14{\%} (3–31{\%}) of global production of maize, wheat, rice, and soybean.

The assessment is based on two trajectories: (a) no adaptation, where the current levels of protection are kept constant, and (b) adaptation, where the level of protection is increased to defend against future flooding events. As a basis for our analysis we use an ensemble-based pan-European flood hazard assessment for present and future conditions. Socio-economic impacts are estimated by combining flood inundation maps with information on assets exposure and vulnerability. Ensemble-based results indicate that current expected annual population affected of ca. 200,000 is projected to increase up to 360,000 due to the effects of socio-economic development and climate change. Under the no adaptation trajectory current expected annual damages of €5.5billion/year are projected to reach €98billion/year by the 2080s due to the combined effects of socio-economic and climate change. Under the adaptation trajectory the avoided damages (benefits) amount to €53billion/year by the 2080s. An analysis of the potential costs of adaptation associated with the increase in protection suggests that adaptation could be highly cost-effective. There is, however, a wide range around these central numbers reflecting the variability in projected climate. Analysis at the country level shows high damages, and by association high costs of adaptation, in the United Kingdom, France, Italy, Romania, Hungary and Czech Republic. At the country level, there is an even wider range around these central values, thus, pointing to a need to consider climate uncertainty in formulating practical adaptation strategies.}, author = {Rojas, Rodrigo and Feyen, Luc and Watkiss, Paul}, doi = {10.1016/j.gloenvcha.2013.08.006}, issn = {09593780}, journal = {Global Environmental Change}, month = {dec}, number = {6}, pages = {1737--1751}, title = {{Climate change and river floods in the European Union: Socio-economic consequences and the costs and benefits of adaptation}}, url = {http://linkinghub.elsevier.com/retrieve/pii/S0959378013001416 https://linkinghub.elsevier.com/retrieve/pii/S0959378013001416}, volume = {23}, year = {2013} } @article{Rojas-Downing2017, abstract = {Global demand for livestock products is expected to double by 2050, mainly due to improvement in the worldwide standard of living.

This study reviews the global impacts of climate change on livestock production, the contribution of livestock production to climate change, and specific climate change adaptation and mitigation strategies in the livestock sector. Livestock production will be limited by climate variability as animal water consumption is expected to increase by a factor of three, demand for agricultural lands increase due to need for 70{\%} growth in production, and food security concern since about one-third of the global cereal harvest is used for livestock feed. Meanwhile, the livestock sector contributes 14.5{\%} of global greenhouse gas (GHG) emissions, driving further climate change. Consequently, the livestock sector will be a key player in the mitigation of GHG emissions and improving global food security. Therefore, in the transition to sustainable livestock production, there is a need for: a) assessments related to the use of adaptation and mitigation measures tailored to the location and livestock production system in use, and b) policies that support and facilitate the implementation of climate change adaptation and mitigation measures.}, author = {Rojas-Downing, M.

A correlation analysis revealed that runoff changes are tightly linked to changes in rainfall (R = 0.49), and to a smaller extent also to changes in potential evapotranspiration. Other parameters than climate – such as the carbon effect on plant water efficiency, land use dynamics or water withdrawals – could also significantly impact on runoff, but they generally do not offset the effects of climate change. In view of the potential changes, the large uncertainty therein and the high vulnerability of the region to such changes, there is an urgent need for integrated studies that quantify the potential effects of these processes on water resources in West Africa and for more accuracy in climate models rainfall projections.

Validation with historical mass balance observations shows the model performs well and the uncertainty is well captured.

Based on our experience preparing scientists for similar careers, we offer a perspective on a path for the academy to better develop, train and support scientists to conduct societally relevant research. We emphasize the need for science training that builds collaborative science skills at different career stages to develop a strong community of practice around actionable climate science. We offer insights from our training and capacity-building programs to demonstrate this transformation, and point to strategies that can be adopted at other universities to grow the capacity of scientists to support society in achieving rapid progress on climate action.}, author = {Rozance, Mary Ann and Krosby, Meade and Meadow, Alison M and Snover, Amy and Ferguson, Daniel B and Owen, Gigi}, doi = {10.1088/1748-9326/abc27a}, issn = {1748-9326}, journal = {Environmental Research Letters}, number = {12}, pages = {125008}, publisher = {IOP Publishing}, title = {{Building capacity for societally engaged climate science by transforming science training}}, url = {http://dx.doi.org/10.1088/1748-9326/abc27a}, volume = {15}, year = {2020} } @article{Ruane2016, abstract = {{\textless}p{\textgreater}{\textless}p{\textgreater}{\textless}strong{\textgreater}Abstract.{\textless}/strong{\textgreater} This paper describes the motivation for the creation of the Vulnerability, Impacts, Adaptation and Climate Services (VIACS) Advisory Board for the Sixth Phase of the Coupled Model Intercomparison Project (CMIP6), its initial activities, and its plans to serve as a bridge between climate change applications experts and climate modelers. The climate change application community comprises researchers and other specialists who use climate information (alongside socioeconomic and other environmental information) to analyze vulnerability, impacts, and adaptation of natural systems and society in relation to past, ongoing, and projected future climate change. Much of this activity is directed toward the co-development of information needed by decision-makers for managing projected risks. CMIP6 provides a unique opportunity to facilitate a two-way dialog between climate modelers and VIACS experts who are looking to apply CMIP6 results for a wide array of research and climate services objectives. The VIACS Advisory Board convenes leaders of major impact sectors, international programs, and climate services to solicit community feedback that increases the applications relevance of the CMIP6-Endorsed Model Intercomparison Projects (MIPs). As an illustration of its potential, the VIACS community provided CMIP6 leadership with a list of prioritized climate model variables and MIP experiments of the greatest interest to the climate model applications community, indicating the applicability and societal relevance of climate model simulation outputs. The VIACS Advisory Board also recommended an impacts version of Obs4MIPs and indicated user needs for the gridding and processing of model output.{\textless}/p{\textgreater}{\textless}/p{\textgreater}}, author = {Ruane, Alex C. and Teichmann, Claas and Arnell, Nigel W. and Carter, Timothy R. and Ebi, Kristie L. and Frieler, Katja and Goodess, Clare M. and Hewitson, Bruce and Horton, Radley and Kovats, R.

Climate information from a suite of global climate models (GCMs) is used to drive models assessing the agricultural impact of changes in temperature, precipitation, carbon dioxide concentrations, river floods, and sea level rise for the 2040–2069 period in comparison to a historical baseline. Using the multi-factor impacts analysis framework developed in Yu et al.

Rice (aman, boro, and aus seasons) and wheat production are simulated in each sub-region using the biophysical Crop Environment REsource Synthesis (CERES) models. These simulations are then combined with the MIKE BASIN hydrologic model for river floods in the Ganges-Brahmaputra-Meghna (GBM) Basins, and the MIKE21 Two-Dimensional Estuary Model to determine coastal inundation under conditions of higher mean sea level. The impacts of each factor depend on GCM configurations, emissions pathways, sub-regions, and particular seasons and crops. Temperature increases generally reduce production across all scenarios. Precipitation changes can have either a positive or a negative impact, with a high degree of uncertainty across GCMs. Carbon dioxide impacts on crop production are positive and depend on the emissions pathway. Increasing river flood areas reduce production in affected sub-regions. Precipitation uncertainties from different GCMs and emissions scenarios are reduced when integrated across the large GBM Basins' hydrology.

In this study, we present projections for the growing season length and growing degree day sum (GDD) in Europe by the end of the 21st century using two threshold temperatures, 5 and 10?°C. The analysis was based on simulations performed with 22?23 CMIP5 global models under the RCP4.5 and RCP8.5 scenarios. Systematic errors in the temporal mean and variability of modelled temperatures were eliminated, and the data were downscaled spatially by employing a bias-correction method. To determine the onset, termination and GDD of the growing season, two methods have been used. The previously developed Fourier method is suited for exploring long-term means, while the novel temperature deviation integral method is applicable to inter-annual variations. According to the multi-model mean of the RCP8.5 simulations in the late 21st century, for the majority of Europe the growing season is prolonged by 1.5?2 months, the GDD above 5?°C increasing by 60?100{\%}. Responses to RCP4.5 are qualitatively similar but smaller. A decomposition of the uncertainty variance reveals that in the near-term future the contribution of internal variability is pronounced, but by the end of the century inter-model differences dominate. In studying growing-season conditions on an annual basis, we found that in coming decades years with a GDD below the recent past (1971?2000) mean become very uncommon.

The largest reduction is anticipated for northern India. The evolution of incident radiation in the mid- and late twenty-first century depends substantially on the emission scenario. According to the representative concentration pathways RCP2.6 and RCP4.5, solar radiation would gradually recover close to the level that prevailed in the late twentieth century. This results from the peaking of aerosol loading before midcentury while the water vapor content continuously increases somewhat. Conversely, under RCP8.5, incident radiation would still decline, although more slowly than during the early century. This coincides with a substantial increase in atmospheric water vapor content and a modest decrease in aerosol forcing. In cloud forcing, multimodel-mean changes are minor, but divergence among the model simulations is substantial. Moreover, cloud forcing proved to be the factor that correlates most strongly with intermodel differences in the solar radiation response. Multimodel-mean changes in solar radiation are small and would not crucially affect the conditions of solar energy production.

In concordance with previous research, the time mean and extreme scalar wind speeds do not change pronouncedly in response to the projected climate change; some degree of weakening occurs in the majority of the domain. Nevertheless, substantial changes in high wind speeds are identified when studying the geostrophic winds from different directions separately. In particular, in northern Europe in autumn and in parts of northwestern Europe in winter, the frequency of strong westerly winds is projected to increase by up to 50{\%}. Concurrently, easterly winds become less common. In addition, we evaluated the potential of the GCMs to simulate changes in the near-surface true wind speeds. In ocean areas, changes in the true and geostrophic winds are mainly consistent and the emerging differences can be explained (e.g., by the retreat of Arctic sea ice). Conversely, in several GCMs the continental wind speed response proved to be predominantly determined by fairly arbitrary changes in the surface properties rather than by changes in the atmospheric circulation.

Avicennia is the most cold-tolerant genus worldwide, and is the subject of most of the observed changes. Avicennia germinans has extended in range along the USA Atlantic coast and expanded into salt marsh as a consequence of lower frost frequency and intensity in the southern USA. The genus has also expanded into salt marsh at its southern limit in Peru, and on the Pacific coast of Mexico. Mangroves of several species have expanded in extent and replaced salt marsh where protected within mangrove reserves in Guangdong Province, China. In south-eastern Australia, the expansion of Avicennia marina into salt marshes is now well documented, and Rhizophora stylosa has extended its range southward, while showing strong population growth within estuaries along its southern limits in northern New South Wales. Avicennia marina has extended its range southwards in South Africa. The changes are consistent with the poleward extension of temperature thresholds coincident with sea-level rise, although the specific mechanism of range extension might be complicated by limitations on dispersal or other factors.

The record begins for the 1976?1977 glacier year and continues to the present. These are equivalent to equilibrium line altitude (ELA) data. An earlier paper used these to estimate annual mass balance and ice volume for all glaciers up to 2008 and showed a steady decline in ice volume, but with considerable inter-annual fluctuations. These results are updated to 2018 for the more than 3,000 small and medium-size glaciers of the Southern Alps. The inclusion of the latter year enabled assessment of the impacts on ice volume of these glaciers from an unprecedented coupled ocean-atmosphere heatwave in the New Zealand region during the austral summer (DJF) 2017/18. The main purpose of this paper is to examine how these changes in ice volume relate to variability and trends in atmospheric circulation and weather types over four decades. Years with ice volume gains are characterized by below average temperature anomalies, enhanced southwest flow and a tendency for trough weather types over New Zealand. Years with ice volume losses have above average temperature, reduced southwest flow, and increased blocking weather types, with more anticyclones east of New Zealand. Largest annual ice volume loss of 3.6 ± 0.6 km3 (?13.5{\%}) occurred during the 2017/18 summer heatwave for which the main atmospheric anomalies are discussed. Total ice volume of the Southern Alps for the small and medium glaciers has decreased from 26.6 km3 in 1977 to 17.9 km3 in 2018 (a loss of 8.6 km3 or 33{\%}) at a rate of 0.21 km3 a?1. From 1977 to 1997 there was an annual ice gain of +0.30 km3 a?1 but was followed by an accelerating ice loss of ?0.67 km3 a?1 for the period 1998?2018. There are significant correlations between ice volume changes and the Trenberth regional circulation indices Z1, Z3 and MZ3. Strongest relationships are with the Southern Annular Mode: a trend towards more positive values coincides with a general loss of ice volume. The Inter-decadal Pacific Oscillation and El Ni{\~{n}}o/Southern Oscillation relate to ice volume changes on decadal to inter-annual time scales. Positive phases of the Inter-decadal Pacific Oscillation and El Ni{\~{n}}o years favour ice volume growth as they are cooler, with more precipitation, troughs and southwest flow over New Zealand. Negative phases of the Inter-decadal Pacific Oscillation and La Ni{\~{n}}a years favour ice volume loss as they are warmer with less precipitation, more anticyclones and east or northeast flow. The dominant driver for 2017/18 was the positive Southern Annular Mode, and a smaller contribution from La Ni{\~{n}}a on a background of regional warming.

Papers providing projections of future heat-related mortality were critically reviewed with a focus on the use of climate model data. Some best practice guidelines are proposed for future research. Methods The electronic databases Web of Science and PubMed/Medline were searched for papers containing a quantitative estimate of future heat-related mortality. The search was limited to papers published in English in peer-reviewed journals up to the end of March 2017. Reference lists of relevant papers and the citing literature were also examined. The wide range of locations studied and climate data used prevented a meta-analysis. Results A total of 608 articles were identified after removal of duplicate entries, of which 63 were found to contain a quantitative estimate of future mortality from hot days or heat waves. A wide range of mortality models and climate model data have been used to estimate future mortality. Temperatures in the climate simulations used in these studies were projected to increase. Consequently, all the papers indicated that mortality from high temperatures would increase under a warming climate. The spread in projections of future climate by models adds substantial uncertainty to estimates of future heat-related mortality. However, many studies either did not consider this source of uncertainty, or only used results from a small number of climate models. Other studies showed that uncertainty from changes in populations and demographics, and the methods for adaptation to warmer temperatures were at least as important as climate model uncertainty. Some inconsistencies in the use of climate data (for example, using global mean temperature changes instead of changes for specific locations) and interpretation of the effects on mortality were apparent. Some factors which have not been considered when estimating future mortality are summarised. Conclusions Most studies have used climate data generated using scenarios with medium and high emissions of greenhouse gases. More estimates of future mortality using climate information from the mitigation scenario RCP2.6 are needed, as this scenario is the only one under which the Paris Agreement to limit global warming to 2°C or less could be realised. Many of the methods used to combine modelled data with local climate observations are simplistic. Quantile-based methods might offer an improved approach, especially for temperatures at the ends of the distributions. The modelling of adaptation to warmer temperatures in mortality models is generally arbitrary and simplistic, and more research is needed to better quantify adaptation. Only a small number of studies included possible changes in population and demographics in their estimates of future mortality, meaning many estimates of mortality could be biased low.

While previous studies have documented changes in the timing of spring green-up and flowering across different parts of the world, empirical evidence regarding how such ongoing ecological changes impact allergic disease burden at population level is lacking. Because earlier spring green-up may increase season length for tree pollen, we hypothesized that early onset of spring (negative anomaly in start of season (SOS)) will be associated with increased hay fever burden. To test this, we first calculated a median cardinal date for SOS for each county within the contiguous US for the years 2001–2013 using phenology data from the National Aeronautics and Space Administration's Moderate Resolution Imaging Spectroradiometer (MODIS). We categorized yearly deviations in SOS for each county from their respective long-term averages as: very early ({\textgreater}3 wks early), early (1–3 wks early), average (within 1 wk), late (1–3 wks late) and very late ({\textgreater} 3 wks late). We linked these data to 2002–2013 National Health Interview Survey data, and investigated the association between changes in SOS and hay fever prevalence using logistic regression. We observed that adults living in counties with a very early onset of SOS had a 14{\%} higher odds of hay fever compared to the reference group, i.e. those living in counties where onset of spring was within the normal range (Odds Ratios (OR): 1.14. 95{\%} Confidence Interval (CI): 1.03–1.27). Likewise, adults living in counties with very late onset of SOS had a 18{\%} higher odds hay fever compared to the reference group (OR: 1.18, CI: 1.05–1.32). Our data provides the first-ever national scale assessment of the impact of changing plant phenology–linked to ongoing climate variability and change–on hay fever prevalence.

The results show that the CORDEX simulation ensemble captures the spatial distribution and the annual cycle of climate variables and PVP over West Africa, though with few biases. The simulation and observation indicate that PVP over West Africa ranges from 8{\%} to 25{\%} and the annual cycle is influenced by the seasonal variation of the monsoon system. The simulation ensemble projects a decrease of PVP over West Africa in the future and indicates that the magnitude of the decrease grows with warming levels.

Similarly, a general increase in CSPOUT (up to 2{\%}) is projected over the continent under both the RCP2.6 and RCP8.5 scenarios.

Among the possible causes, habitat change is discussed. This article focuses on potentially increased levels of fine sediments going to rivers and their effects on gravel-spawning brown trout. Indications of increased erosion rates are evident from land-use change in agriculture, changes in forest management practices, and from climate change. The latter induces an increase in air and river water temperatures, reduction in permafrost, changes in snow dynamics and an increase in heavy rain events. As a result, an increase in river sediment is likely. Suspended sediment may affect fish health and behaviour directly. Furthermore, sediment loads may clog gravel beds impeding fish such as brown trout from spawning and reducing recruitment rates. To assess the potential impact on fine sediments, knowledge of brown trout reproductive needs and the effects of sediment on brown trout health were evaluated. APPROACH: We critically reviewed the literature and included results from ongoing studies to answer the following questions, focusing on recent decades and rivers in alpine countries. Have climate change and land-use change increased erosion and sediment loads in rivers? Do we have indications of an increase in riverbed clogging? Are there indications of direct or indirect effects on brown trout from increased suspended sediment concentrations in rivers or from an increase in riverbed clogging? RESULTS: Rising air temperatures have led to more intensive precipitation in winter months, earlier snow melt in spring, and rising snow lines and hence to increased erosion. Intensification of land use has supported erosion in lowland and pre-alpine areas in the second half of the twentieth century. In the Alps, however, reforestation of abandoned land at high altitudes might reduce the erosion risk while intensification on the lower, more easily accessible slopes increases erosion risk. Data from laboratory experiments show that suspended sediments affect the health and behaviour of fish when available in high amounts. Point measurements in large rivers indicate no common lethal threat and suspended sediment is rarely measured continuously in small rivers. However, effects on fish can be expected under environmentally relevant conditions. River bed clogging impairs the reproductive performance of gravel-spawning fish. DISCUSSION: Overall, higher erosion and increased levels of fine sediment going into rivers are expected in future. Additionally, sediment loads in rivers are suspected to have considerably impaired gravel bed structure and brown trout spawning is impeded. Timing of discharge is put forward and is now more likely to affect brown trout spawning than in previous decades. CONCLUSIONS: Reports on riverbed clogging from changes in erosion and fine sediment deposition patterns, caused by climate change and land-use change are rare. This review identifies both a risk of increases in climate erosive forces and fine sediment loads in rivers of alpine countries. Increased river discharge and sediment loads in winter and early spring could be especially harmful for brown trout reproduction and development of young life stages. Recently published studies indicate a decline in trout reproduction from riverbed clogging in many rivers in lowlands and alpine regions. However, the multitude of factors in natural complex ecosystems makes it difficult to address a single causative factor. RECOMMENDATIONS AND PERSPECTIVES: Further investigations into the consequences of climate change and land-use change on river systems are needed. Small rivers, of high importance for the recruitment of gravel-spawning fish, are often neglected. Studies on river bed clogging are rare and the few existing studies are not comparable. Thus, there is a strong need for the development of methods to assess sediment input and river bed clogging. As well, studies on the effects to fish from suspended sediments and consequences of gravel beds clogging under natural conditions are urgently needed.}, author = {Scheurer, Karin and Alewell, Christine and B{\"{a}}nninger, Dominik and Burkhardt-Holm, Patricia}, doi = {10.1007/s11356-008-0075-3}, isbn = {0944-1344}, issn = {09441344}, journal = {Environmental Science and Pollution Research}, keywords = {Agriculture,Alpine region,Brown trout,Climate change,Clogging erosion,Fish health,Global change,Gravel-spawning,Hydrology,Land-use change,Precipitation,Reproduction,Rivers,Salmo trutta,Salmonids,Suspended sediment}, month = {mar}, number = {2}, pages = {232--242}, pmid = {19048320}, publisher = {Springer-Verlag}, title = {{Climate and land-use changes affecting river sediment and brown trout in alpine countries – a review}}, url = {http://link.springer.com/10.1007/s11356-008-0075-3}, volume = {16}, year = {2009} } @article{Schewe2014, abstract = {Water scarcity severely impairs food security and economic prosperity in many countries today. Expected future population changes will, in many countries as well as globally, increase the pressure on available water resources. On the supply side, renewable water resources will be affected by projected changes in precipitation patterns, temperature, and other climate variables. Here we use a large ensemble of global hydrological models (GHMs) forced by five global climate models and the latest greenhouse-gas concentration scenarios (Representative Concentration Pathways) to synthesize the current knowledge about climate change impacts on water resources. We show that climate change is likely to exacerbate regional and global water scarcity considerably. In particular, the ensemble average projects that a global warming of 2 °C above present (approximately 2.7 °C above preindustrial) will confront an additional approximate 15{\%} of the global population with a severe decrease in water resources and will increase the number of people living under absolute water scarcity ({\textless}500 m(3) per capita per year) by another 40{\%} (according to some models, more than 100{\%}) compared with the effect of population growth alone. For some indicators of moderate impacts, the steepest increase is seen between the present day and 2 °C, whereas indicators of very severe impacts increase unabated beyond 2 °C. At the same time, the study highlights large uncertainties associated with these estimates, with both global climate models and GHMs contributing to the spread.

In the face of climate change, the assessment of land transport infrastructure exposure towards adverse climate events is of major importance for Europe's economic prosperity and social wellbeing. In this study, a climate index estimating rainfall patterns which trigger landslides in central Europe is analysed until the end of this century and compared to present-day conditions. The analysis of the potential future development of landslide risk is based on an ensemble of dynamically downscaled climate projections which are driven by the SRES A1B socio-economic scenario. Resulting regional-scale climate change projections across central Europe are concatenated with Europe's road and railway network. Results indicate overall increases of landslide occurrence. While flat terrain at low altitudes exhibits an increase of about 1 more potentially landslide-inducing rainfall period per year until the end of this century, higher elevated regions are more affected and show increases of up to 14 additional periods. This general spatial distribution emerges in the near future (2021–2050) but becomes more pronounced in the remote future (2071–2100). Since largest increases are to be found in Alsace, potential impacts of an increasing amount of landslides are discussed using the example of a case study covering the Black Forest mountain range in Baden-W{\"{u}}rttemberg by further enriching the climate information with additional geodata.

Uncertainty in the future of tropical and subtropical drylands is well constrained, whereas soil moisture and ecological droughts, which drive vegetation productivity and composition, remain poorly understood in temperate drylands.

Robust appraisals of climate impacts at different levels of global-mean temperature increase are vital to guide assessments of dangerous anthropogenic interference with the climate system. The 2015 Paris Agreement includes a two-headed temperature goal: "holding the increase in the global average temperature to well below 2{\&}deg;C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5{\&}deg;C". Despite the prominence of these two temperature limits, a comprehensive overview of the differences in climate impacts at these levels is still missing. Here we provide an assessment of key impacts of climate change at warming levels of 1.5{\&}deg;C and 2{\&}deg;C, including extreme weather events, water availability, agricultural yields, sea-level rise and risk of coral reef loss. Our results reveal substantial differences in impacts between a 1.5{\&}deg;C and 2{\&}deg;C warming that are highly relevant for the assessment of dangerous anthropogenic interference with the climate system. For heat-related extremes, the additional 0.5{\&}deg;C increase in global-mean temperature marks the difference between events at the upper limit of present-day natural variability and a new climate regime, particularly in tropical regions. Similarly, this warming difference is likely to be decisive for the future of tropical coral reefs. In a scenario with an end-of-century warming of 2{\&}deg;C, virtually all tropical coral reefs are projected to be at risk of severe degradation due to temperature-induced bleaching from 2050 onwards. This fraction is reduced to about 90{\%} in 2050 and projected to decline to 70{\%} by 2100 for a 1.5{\&}deg;C scenario. Analyses of precipitation-related impacts reveal distinct regional differences and hot-spots of change emerge. Regional reduction in median water availability for the Mediterranean is found to nearly double from 9{\%} to 17{\%} between 1.5{\&}deg;C and 2{\&}deg;C, and the projected lengthening of regional dry spells increases from 7 to 11{\%}. Projections for agricultural yields differ between crop types as well as world regions. While some (in particular high-latitude) regions may benefit, tropical regions like West Africa, South-East Asia, as well as Central and northern South America are projected to face substantial local yield reductions, particularly for wheat and maize. Best estimate sea-level rise projections based on two illustrative scenarios indicate a 50cm rise by 2100 relative to year 2000-levels for a 2{\&}deg;C scenario, and about 10 cm lower levels for a 1.5{\&}deg;C scenario. In a 1.5{\&}deg;C scenario, the rate of sea-level rise in 2100 would be reduced by about 30{\%} compared to a 2{\&}deg;C scenario. Our findings highlight the importance of regional differentiation to assess both future climate risks and different vulnerabilities to incremental increases in global-mean temperature.

Northern India (23–31° N, 68–90° E) is one of the most densely populated and polluted regions in world. Accurately modeling pollution in the region is difficult due to the extreme conditions with respect to emissions, meteorology, and topography, but it is paramount in order to understand how future changes in emissions and climate may alter the region's pollution regime. We evaluate the ability of a developmental version of the new-generation NOAA GFDL Atmospheric Model, version 4 (AM4) to simulate observed wintertime fine particulate matter (PM2.5) and its relationship to meteorology over Northern India. We compare two simulations of GFDL-AM4 nudged to observed meteorology for the period 1980–2016 driven by pollutant emissions from two global inventories developed in support of the Coupled Model Intercomparison Project Phases 5 (CMIP5) and 6 (CMIP6), and compare results with ground-based observations from India's Central Pollution Control Board (CPCB) for the period 1 October 2015–31 March 2016. Overall, our results indicate that the simulation with CMIP6 emissions produces improved concentrations of pollutants over the region relative to the CMIP5-driven simulation. While the particulate concentrations simulated by AM4 are biased low overall, the model generally simulates the magnitude and daily variability of observed total PM2.5. Nitrate and organic matter are the primary components of PM2.5 over Northern India in the model. On the basis of correlations of the individual model components with total observed PM2.5 and correlations between the two simulations, meteorology is the primary driver of daily variability. The model correctly reproduces the shape and magnitude of the seasonal cycle of PM2.5, but the simulated diurnal cycle misses the early evening rise and secondary maximum found in the observations. Observed PM2.5 abundances are by far the highest within the densely populated Indo-Gangetic Plain, where they are closely related to boundary layer meteorology, specifically relative humidity, wind speed, boundary layer height, and inversion strength.

For this reason, understanding flood dynamics on both local and regional scales is critical. However, flood hazard studies to date typically rely on single flooding events to create flood maps and to evaluate flood hazards using satellite imagery. Here we use geographic information systems to analyze weekly water level data from 304 river gauges and over 1200 groundwater gauges from the Bangladesh Water Development Board to determine the spatial and temporal changes in flood depth and extent. These data cover an eight year period from 2002 to 2010 and provide a temporal resolution that match or are better than that of available satellite imagery. Country-wide ground and surface water levels and corresponding annual flooding events were determined along with groundwater level, flooding, and precipitation trends in Bangladesh at multiple scales. We find that while precipitation within the GBM basin has steadily increased through the time series, the average country-wide inundation depth and absolute water level has been decreasing. These respective trends could be attributed to improved flood management strategies in Bangladesh and surrounding countries that are within the GBM basin, as well as fluctuating weather patterns, declining volume of Himalayan snowmelt runoff, dam construction upriver from the GBD both within and outside the Bangladesh border, and increased groundwater abstraction of shallow groundwater aquifers for sustaining life in the eighth most populous country in the world.}, author = {Sciance, Marc Benjamin and Nooner, Scott L}, doi = {10.1007/s11069-017-3036-7}, issn = {1573-0840}, journal = {Natural Hazards}, number = {1}, pages = {115--135}, title = {{Decadal flood trends in Bangladesh from extensive hydrographic data}}, url = {https://doi.org/10.1007/s11069-017-3036-7}, volume = {90}, year = {2018} } @article{Scott2018, abstract = {The aim of the paper is to present a story about the 2015 to early 2017 Windhoek drought in the context of climate change while using the narrative approach. The story that is presented here is derived from the engagement of participants in a transdisciplinary, co-productive workshop, the Windhoek Learning Lab 1 (March 2017), as part of the FRACTAL Research Programme. The results show that the story starts with the ‘complication' where the drought had reached crisis levels where the water demand increasingly exceeded the supply in the face of the drought. The City of Windhoek (CoW) was unable to address the problem, particularly the recharging of the Windhoek aquifer due to lack of funding. Phase 2 then shows four reactions to the drought: water conservation by water demand management; a Water Saving campaign; the Windhoek Managed Aquifer Recharge Scheme; and, the setting up of the Cabinet Technical Committee of Supply Security. The resolution of the story, Phase 4, is when the national government instructs NamWater to provide the funds for CoW to complete the recharging of the aquifer, which supplied water to the city at the last minute at the end of 2016. The final situation of the story is that ongoing collaborative work by CoW with FRACTAL on the city's burning issues is planned to integrate climate change into future decision making for the longer term. The main actors in the story are the Ministry of Agriculture and NamWater as hero and villain, and CoW a hero, with the victims of the story, the residents of informal settlements. The main learnings from this story are that the lack of decentralization of power and resources serve to exacerbate water crises at the local level and hamper climate adaptation, despite a proactive and innovative local municipality.

It is first shown that state-of-the-art climate models from phase 5 of the Coupled Model Intercomparison Project generally underestimate the degree of aridity of the United States and simulate an arid–humid divide that is too diffuse. These biases are traced to excessive precipitation and evapotranspiration and inadequate blocking of eastward moisture flux by the Pacific coastal ranges and Rockies. Bias-corrected future projections are developed that modify observationally based measures of aridity by the model-projected fractional changes in aridity. Aridity increases across the United States, and the aridity gradient weakens. The main contributor to the changes is rising potential evapotranspiration, while changes in precipitation working alone increase aridity across the southern and decrease across the northern United States. The “effective 100th meridian” moves to the east as the century progresses. In the current farm economy, farm size and percent of county under rangelands increase and percent of cropland under corn decreases as aridity increases.

These quantities are quite unexplored, for past changes as well as for future changes and call for sophisticated methods of analysis. To address this issue, we use Markov chains for the analysis of the dynamics and succession of multivariate or compound extreme events. We apply the method to observational data (1951–2010) and an ensemble of regional climate simulations for central Europe (1971–2000, 2021–2050) for two types of compound extremes, heavy precipitation and cold in winter and hot and dry days in summer. We identify three regions in Europe, which turned out to be likely susceptible to a future change in the succession of heavy precipitation and cold in winter, including a region in southwestern France, northern Germany and in Russia around Moscow. A change in the succession of hot and dry days in summer can be expected for regions in Spain and Bulgaria.

Quantifying the effects of climate change-induced erosivity change is important for identifying critical regions prone to soil erosion under a changing environment. In this study we first evaluate the changes of R from 1970 to 2090 across the United States under nine climate conditions predicted by three general circulation models for three emissions scenarios (A2, A1B, and B1) from the Fourth Assessment Report of the Intergovernmental Panel on Climate Change. Then, we identify watersheds that are most vulnerable to future climate change in terms of soil erosion potential. We develop a novel approach to evaluate future trends of R magnitude and variance by incorporating both the rate of change with time as well as the level of agreement between climatic projections. Our results show that mean decadal R values would increase with time according to all nine climatic projections considered between 1970 and 2090. However, these trends vary widely spatially. In general, catchments in the northeastern and northwestern United States are characterized by strong increasing trends in R, while the trends in the midwestern and southwestern United States are either weak or inconsistent among the nine climatic projections considered. The northeastern and northwestern United States will likely experience a significant increase in annual variability of R (i.e., increase in extreme events). Conversely the variability of R is unlikely to change in large areas of the Midwest. At the watershed scale (8-digit Hydrologic Unit Code), the mean vulnerability to erosion scores vary between -0.12 and 0.35 with a mean of 0.04. The five hydrologic regions with the highest mean vulnerability to erosion are 5, 6, 2, 1, and 17, with values varying between 0.06 and 0.09. These regions occupy large areas of Ohio, Maryland, Indiana, Vermont, and Illinois, with mean erosion vulnerability score statewide above 0.08.

The results show that cloud cover has significantly decreased over the last decades.

Correlation analyses indicate that the El Ni{\~{n}}o phenomenon affects the interannual variability of cloudiness in the Amazon, leading to delayed onset and early demise of the rainy season. The tropical South Atlantic, the Pacific warm pool, and the North Atlantic tripole also play a small, but significant, role in the Amazon's cloudiness variability. The decrease in cloudiness over the Amazon basin reduces the amount of solar radiation reflected back to space while increasing irradiance at the surface. This local warming alters surface heat fluxes and the atmospheric thermodynamic profile, further affecting cloud development.

Trends in indices of climate extremes are studied for the South Asian region using high-quality records of daily temperature and precipitation observations. Data records from 210 (265) temperature (precipitation) observation stations are analysed over the period 1971?2000 (1961?2000). Spatial maps of station trends, time series of regional averages and frequency distribution analysis form the basis of this study. Due to the highly diverse geography of the South Asian region, the results are also described for some specific regions, such as the island of Sri Lanka; the tropical region (excluding Sri Lanka); the Greater Himalayas above 35°N, the Eastern Himalayas (Nepal) and the Thar Desert. Generally, changes in the frequency of temperature extremes over South Asia are what one would expect in a warming world; warm extremes have become more common and cold extremes less common. The warming influence is greater in the Eastern Himalayas compared with that in the Greater Himalayas. The Thar Desert also shows enhanced warming, but increases are mostly less than in the Eastern Himalayas. Changes in the indices of extreme precipitation are more mixed than those of temperature, with spatially coherent changes evident only at relatively small scales. Nevertheless, most extreme precipitation indices show increases in the South Asia average, consistent with globally averaged results. The indices trends are further studied in the context of Atmospheric Brown Clouds (ABCs) over the region. Countries falling within the ABC hotspot namely Indo-Gangetic Plain (IGP) have shown a different behaviour on the trends of extreme indices compared with the parts outside this hotspot.

GCM-derived wind fields forced the global WAVEWATCH-III wave model to generate hourly time series of bulk wave parameters around 25 islands in the mid to western tropical Pacific Ocean for historical (1976-2005), mid-century, and end-century time periods for the December-February and June-August seasons. The December-February regional wave climate is dominated by strong winds and large swell from extratropical cyclones in the north Pacific while the June-August season brings smaller waves generated by the trade winds and swell from Southern Hemisphere extratropical storms. Extreme significant wave heights decreased ({\~{}}. 10.0{\%}) throughout the 21st century under both climate scenarios compared to historical wave conditions and the higher radiative forcing RCP 8.5 scenario displayed a greater and more widespread decrease in extreme significant wave heights compared to the lower forcing RCP 4.5 scenario. An exception was for the end-century June-August season. Offshore of islands in the central equatorial Pacific, extreme significant wave heights displayed the largest changes from historical values. The frequency of extreme events during December-February decreased under RCP 8.5, whereas the frequency increased under RCP 4.5. Mean wave directions rotated more than 30° clockwise at several locations during June-August, which could indicate a weakening of the trade winds' influence on extreme wave directions and increasing dominance of Southern Ocean swell.

While observed trends in such indices can be, and have been, compared with model-simulated trends, their definition relative to each model's own climatology inhibits their use for the evaluation of model-simulated temperature variability. This is unfortunate, as in many parts of the world, indices from observations remain the only source of publicly available information about extreme temperature variability. We approach this problem by introducing a novel adjustment to the standard method for deriving indices from climate models. This involves the removal of the bias in the mean annual cycle of the models and the use of percentile thresholds from a reference data set. We illustrate the technique by comparing daily minimum (TN) and maximum (TX) temperatures from the fifth phase of Coupled Model Intercomparison Project (CMIP5) historical simulations with those from an observation-based data set and from the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) and the European Centre for Medium-Range Weather Forecasts (ERA-40) reanalyses. Biases in the annual cycle also translate into biases in the representation of the percentile indices in the models and reanalyses. Generally, percentile indices based on daily TX are well represented by the models and reanalyses compared to the observations. For percentile indices based on daily minimum temperature, however, large discrepancies occur particularly between the reanalyses. {\textcopyright} 2013 Royal Meteorological Society.}, author = {Sillmann, J. and Kharin, V.

A key barrier to managing these risks is the limited availability of accessible, reliable and relevant weather and climate information. Despite continued investments in Earth System Modelling, and the growing provision of climate services across Africa and India, there often remains a mismatch between available information and what is needed to support on-the-ground decision-making. In this paper, we outline the range of currently available information and present examples from Africa and India to demonstrate the challenges in meeting information needs in different contexts. A review of literature supplemented by interviews with experts suggests that externally provided weather and climate information has an important role in building on local knowledge to shape understanding of climate risks and guide decision-making across scales. Moreover, case studies demonstrate that successful decision-making can be achieved with currently available information. However, these successful examples predominantly use daily, weekly and seasonal climate information for decision-making over short time horizons. Despite an increasing volume of global and regional climate model simulations, there are very few clear examples of long-term climate information being used to inform decisions at sub-national scales.

Even decision-makers involved in long-term planning, such as national government officials, find it difficult to plan using decadal and multi-decadal climate projections because of issues around uncertainty, risk averseness and constraints in justifying funding allocations on prospective risks.

Such measures require appropriate information about likely changes in event frequency and magnitude on relevant spatiotemporal scales. However, to support robust climate information for decision-making, an effective communication between scientists and stakeholders is crucial. In this context, weather event attribution studies are increasingly raising attention beyond academic circles, although the understanding of how to take it beyond academia is still evolving. This paper presents the results of a study that involved in-depth interviews with stakeholders from a range of sectors about potential applications and the general usefulness of event attribution studies. A case study of the hot and dry summer 2012 in southeast Europe is used as a concrete example, with a focus on the applicability of attribution results across sectors. An analysis of the interviews reveals an abundant interest among the interviewed stakeholders and highlights the need for information on the causes and odds of extreme events, in particular on regional scales. From this data key aspects of stakeholder engagement are emerging, which could productively feed back into how probabilistic event attribution studies are designed and communicated to ensure practical relevance and usefulness for the stakeholder community. }, author = {Sippel, Sebastian and Walton, Peter and Otto, Friederike E L}, doi = {10.1175/WCAS-D-14-00045.1}, journal = {Weather, Climate, and Society}, number = {3}, pages = {224--237}, title = {{Stakeholder Perspectives on the Attribution of Extreme Weather Events: An Explorative Enquiry}}, url = {https://doi.org/10.1175/WCAS-D-14-00045.1}, volume = {7}, year = {2015} } @article{Sittaro2017, author = {Sittaro, Fabian and Paquette, Alain and Messier, Christian and Nock, Charles A.}, doi = {10.1111/gcb.13622}, issn = {13541013}, journal = {Global Change Biology}, keywords = {climate change,eastern North America,forest inventory plots,global warming,range shifts,temperate and boreal forests,tree migration}, month = {aug}, number = {8}, pages = {3292--3301}, publisher = {John Wiley {\&} Sons, Ltd (10.1111)}, title = {{Tree range expansion in eastern North America fails to keep pace with climate warming at northern range limits}}, url = {http://doi.wiley.com/10.1111/gcb.13622}, volume = {23}, year = {2017} } @incollection{Sivakumar2018, abstract = {The past few decades, have seen an increase in the intensity and frequency of weather and climate extremes around the world with severe impacts on several socio-economic sectors, especially in the developing world.

A comparative analysis of documentary materials and expert interviews linked to the climate scenarios was per-formed. Our findings reveal a new typology of use-inspired research in climate science for decision-making: (i) innova-tors, where the advancement of science is the main objective; (ii) consolidators, where knowledge exchanges and networks are prioritised; and (iii) collaborators, where the needs of users are put first and foremost. These different values over what constitutes 'good' science for decision-making are mirrored in the way users were involved in the production process: (i) elicitation, where scientists have privileged decision-making power; (ii) representation, where multiple organisations medi-ate on behalf of individual users; and (iii) participation, where a multitude of users interact with scientists in an equal part-nership. These differences help explain why climate knowledge gains its credibility and legitimacy differently even when the information itself might not be judged as salient and usable.

Permafrost extent diagnosed directly from each climate model's soil temperature is a function of the modeled surface climate as well as the ability of the land surfacemodel to represent permafrost physics. For each CMIP5 model these two effects are separated by using indirect estimators of permafrost driven by climatic indices and compared to permafrost extent directly diagnosed via soil temperatures. Several robust conclusions can be drawn from this analysis. Significant air temperature and snow depth biases exist in some model's climates, which degrade both directly and indirectly diagnosed permafrost conditions. The range of di- rectly calculated present-day (1986–2005) permafrost area is extremely large (;4–25 3 106km2). Several land models contain structural weaknesses that limit their skill in simulating cold region subsurface processes. The sensitivity of future permafrost extent to temperature change over the present-day observed permafrost region averages (1.676 0.7)3 106km2 8C21 but is a function of the spatial and temporal distribution of climate change. Because of sizable differences in future climates for the representative concentration pathway (RCP) emission scenarios, a wide variety of future permafrost states is predicted by 2100.

Multiple regions in the Pacific, Atlantic and Indian Oceans are particularly vulnerable to MHW intensification, due to the co-existence of high levels of biodiversity, a prevalence of species found at their warm range edges or concurrent non-climatic human impacts. The physical attributes of prominent MHWs varied considerably, but all had deleterious impacts across a range of biological processes and taxa, including critical foundation species (corals, seagrasses and kelps).

To address this problem we use downscaled daily climate predictions from seven GCMs to run a continental-scale hydrological model for a process-based representation of mosquito breeding habitat availability. A more complex pattern of malaria suitability emerges as water is routed through drainage networks and river corridors serve as year-round transmission foci.

The events are selected out of 13 hourly 10 m wind speed records that are part of a high quality dataset of near-surface wind observations at Dutch meteorological stations. Comparisons are made with trends in independent wind events selected from geostrophic wind speed records and reanalysis data. The results for moderate wind events (that occur on average 10 times per year) and strong wind events (that occur on average twice a year) indicate a decrease in storminess over the Netherlands between 5 and 10{\%}/decade. This result is inconsistent with National Centers for Environmental Prediction–National Center for Atmospheric Research or European Centre for Medium-Range Weather Forecasts reanalysis data, which suggest increased storminess during the same 41 year period. Possible explanations are given for the discrepancy between the trends in storminess based on station data and the trends in storminess based on reanalysis data. Evaluation of trends in geostrophic wind, both from station data and reanalysis data, and evaluation of trends in vector-averaged (upscaled) 10 m wind over the Netherlands point towards inhomogeneities in the reanalysis data as the main cause of the discrepancy. We conclude that it is likely that the decrease in storminess observed in Dutch station records of near-surface wind in the past four decades is closer to reality than the increase suggested by the reanalysis data.

The extreme precipitation was a result of unusually strong recurrent patterns of atmospheric and oceanic conditions, including extremely warm coastal sea surface temperatures (SST) and weakened trade winds. These climatic features and their causal relationship with the Peruvian precipitation were examined. Diagnostic analysis and model experiments suggest that an atmospheric forcing in early 2017, which was moderately linked to the Trans-Ni{\~{n}}o Index (TNI), initiated the local SST warming along coastal Peru that later expanded to the equator. In January 2017, soil moisture was increased by an unusual expansion of Amazonian rainfall. By March, localized and robust SST warming provided positive feedback to the weakening of the trade winds, leading to increased onshore wind and a subsequent enhancement in rainfall. The analysis points to a tendency towards more frequent and stronger variations in the water vapor flux convergence along the equator, which is associated with the increased precipitation in coastal Peru.}, author = {Son, Rackhun and Wang, S.-Y.

Although the role of reduction in Arctic sea ice in recent cold and snowy winters is still a matter of debate, there is considerable interest in determining whether such an emerging climate feedback will persist into the future in a warming environment. Here we show that increased winter snowfall would be a robust feature throughout the 21st century in the northeastern Europe, central and northern Asia and northern North America as projected by current-day climate model simulations under the medium mitigation scenario. We argue that the increased winter snowfall in these regions during the 21st century is due primarily to the diminishing autumn Arctic sea ice (largely externally forced). Variability of the winter Arctic Oscillation (dominant mode of natural variability in the Northern Hemisphere), in contrast, has little contribution to the increased winter snowfall. This is evident in not only the multi-model ensemble mean, but also each individual model (not model-dependent). Our findings reinforce suggestions that a strong sea ice-snowfall feedback might have emerged, and would be enhanced in coming decades, increasing the chance of heavy snowfall events in northern high-latitude continents.}, author = {Song, Mirong and Liu, Jiping}, doi = {10.1007/s13131-017-1021-3}, issn = {1869-1099}, journal = {Acta Oceanologica Sinica}, number = {8}, pages = {34--41}, title = {{The role of diminishing Arctic sea ice in increased winter snowfall over northern high-latitude continents in a warming environment}}, url = {https://doi.org/10.1007/s13131-017-1021-3}, volume = {36}, year = {2017} } @article{Soret_2019, abstract = {Both renewable energy supply and electricity demand are strongly influenced by meteorological conditions and their evolution over time in terms of climate variability and climate change.

Drought frequency is defined as the number of drought events occurred, drought duration as the number of months in drought conditions, and drought severity as the sum of the integral area below zero of each event. Because drought is mainly driven by rainfall deficits, we chose the Standardized Precipitation Index (SPI) as the base indicator to derive drought-related quantities. SPI-12 has been calculated on a monthly basis using a Gamma distribution fitted to a 60-year baseline period (1951?2010). Global grids (0.5°???0.5°) of the Full Data Reanalysis Version 6.0 dataset provided by the Global Precipitation Climatology Centre (GPCC) have been used as precipitation data input. The regions most exposed to prolonged and severe droughts during 1951?1970 were the Central United States, the Argentinian Pampas, Russia, and Central Australia; during 1971?1990 they were Southern Chile, the Sahel, and Siberia; during 1991?2010 they were the Amazon Forest, the Congo River Basin, Mongolia, North Eastern China, and Borneo. A linear trend analysis between 1951 and 2010 shows a small global increase in each drought component, but drought frequency decreased in the Northern Hemisphere.

Using a new dataset made of 4023 daily TN–TM–TX series for the period 2001–2011 and 3897 monthly TM homogenized series for the period 1951–2011, we computed CDD, HDD, GDD, and Winkler Index (WI) for Europe.

A set of parameters for each station was then applied to the corresponding 1951–2011 monthly records. We interpolated the parameters and the reconstructed degree-day series onto a European 0.25° × 0.25° grid: with these gridded parameters, one can estimate the degree-days for any European location if only monthly TM is available.

Under projected future global warming, such a tendency can be expected to persist until the end of this century and beyond. Identifying which climate-related impacts are likely to increase, and by how much, is an important element of any effective strategy for managing future climate risks. This study investigates whether energy demand for cooling and heating buildings can be expected to increase or decrease under climate change. Two indicators of weather-related energy consumption for heating and cooling buildings are considered: heating degree-days (HDD) and cooling degree-days (CDD). The evolution of these indicators has been analysed based on 11 high-resolution bias-adjusted EURO-CORDEX simulations for two emission representative concentration pathways (RCP4.5 and RCP8.5). Both indicators have been validated over the period 1981–2010 using an independent data set that contains more than 4000 station data, showing very high correlation over most of Europe. Trends of HDD and CDD from 1981 to 2100, together with their uncertainties, are analysed. For both RCPs, all simulations project a significant decrease for HDD, especially over Scandinavia and European Russia, and an increase of CDD which peaks over the Mediterranean region and the Balkans. Overall, degree-day trends do not show remarkable differences if population weighting is applied. If a constant population scenario is considered, the decrease in HDD will outbalance the increase in CDD in the 21st century over most of Europe. Thus the related energy demand (expressed as Energy Degree-days, EDD) is expected to decrease. If, however, population projections over the 21st century are included in the calculations, it is shown that despite the persisting warming, EDD will increase over northern Europe, the Baltic countries, Great Britain, Ireland, Benelux, the Alps, Spain, and Cyprus, resulting in an overall increase in EDD over Europe.}, author = {Spinoni, Jonathan and Vogt, J{\"{u}}rgen V and Barbosa, Paulo and Dosio, Alessandro and McCormick, Niall and Bigano, Andrea and F{\"{u}}ssel, Hans-Martin}, doi = {10.1002/joc.5362}, issn = {08998418}, journal = {International Journal of Climatology}, month = {apr}, number = {S1}, pages = {e191--e208}, title = {{Changes of heating and cooling degree-days in Europe from 1981 to 2100}}, url = {http://doi.wiley.com/10.1002/joc.5362}, volume = {38}, year = {2018} } @article{Staiger2019, abstract = {Application of thermal indices has become very popular over the last three decades.

As predicted, latitude of origin and carbon dioxide level significantly influenced the timing and magnitude of flowering. Reproductive onset occurred earlier with increasing latitude, with concurrent increases in the number of flowers produced. Elevated carbon dioxide resulted in earlier reproductive onset in all ecotypes, which was significantly more pronounced in the northern populations. We interpret our findings as evidence for ecotypic variation in ragweed flowering time, as well in responses to CO2. Thus, the ecological and human health implications of common ragweed's response to global change are likely to depend on latitude. We conclude that increased flower production, duration, and possibly pollen output, can be expected in Northeastern United States with rising levels of CO2.

Results show that the main periods of extreme drought occurred simultaneously throughout the country in 1992–1993 and 2003–2004, except for 2015–2016, when it was not identified in the southern region. In addition, a slight temporal lag was identified latitudinally (north–south) at the beginning of dry conditions, revealing the largest difference between the northern and southern regions. A positive trend in the time series of both indices (SPEI and SPI) prevailed in all sub-regions, with the SPEI minus SPI difference always being negative, suggesting the importance of temperature and evapotranspiration for this trend. Further detailed analyses were then performed using SPEI at 1-month and 12-months timescales for all climate sub-regions, as well as the main indicators to characterize duration and severity. Results show that the number of drought episodes did not vary much between regions, but they did vary in duration and severity at the annual scale. Moreover, changes in the soil root zone are largely associated with dry and wet conditions not only from season to season, but also in longer accumulation periods and more strongly in the northern regions of Vietnam. Indeed, a study of the most severe drought episodes also revealed the occurrence of negative anomalies of the root-soil moisture in the subsequent four or more months. Dynamic atmospheric conditions associated with the peak of most severe drought episodes show the crucial role of subsidence of dry air in the middle and high atmosphere, which prevents convection in the lower troposphere.

However, operational seasonal forecasting systems have little or no value unless they are able to change key management decisions. Changed decision making through incorporation of seasonal forecasting ultimately has to demonstrate improved long-term performance of the cropping enterprise. Simulation analyses conducted on specific production scenarios are especially useful in improving decisions, particularly if this is done in conjunction with development of decision-support systems and associated facilitated discussion groups. Improved management of the overall crop production system requires an interdisciplinary approach, where climate scientists, agricultural scientists and extension specialists are intimately linked with crop production managers in the development of targeted seasonal forecast systems. The same principle applies in developing improved operational management systems for commodity trading organizations, milling companies and agricultural marketing organizations.

It is therefore challenging to detect systematic changes in their occurrence given the relative shortness of observational records. However, there is a clear interest from outside the climate science community in the extent to which recent damaging extreme events can be linked to human-induced climate change or natural climate variability. Event attribution studies seek to determine to what extent anthropogenic climate change has altered the probability or magnitude of particular events. They have shown clear evidence for human influence having increased the probability of many extremely warm seasonal temperatures and reduced the probability of extremely cold seasonal temperatures in many parts of the world. The evidence for human influence on the probability of extreme precipitation events, droughts, and storms is more mixed. Although the science of event attribution has developed rapidly in recent years, geographical coverage of events remains patchy and based on the interests and capabilities of individual research groups. The development of operational event attribution would allow a more timely and methodical production of attribution assessments than currently obtained on an ad hoc basis. For event attribution assessments to be most useful, remaining scientific uncertainties need to be robustly assessed and the results clearly communicated. This requires the continuing development of methodologies to assess the reliability of event attribution results and further work to understand the potential utility of event attribution for stakeholder groups and decision makers.

We find that relative to the 1981-2010 reference period, recent anomalies in spring and winter sea ice coverage have been more significant than any observed drop in summer sea ice extent (SIE) throughout the satellite period. For example, the SIE in May and November 2016 was almost four standard deviations below the reference SIE in these months. Decadal ice loss during winter months has accelerated from -2.4 {\%}/decade from 1979 to 1999 to -3.4{\%}/decade from 2000 onwards. We also examine regional ice loss and find that for any given region, the seasonal ice loss is larger the closer that region is to the seasonal outer edge of the ice cover. Finally, across all months, we identify a robust linear relationship between pan-Arctic SIE and total anthropogenic CO2 emissions. The annual cycle of Arctic sea ice loss per ton of CO2 emissions ranges from slightly above 1 m2 throughout winter to more than 3 m2 throughout summer. Based on a linear extrapolation of these trends, we find the Arctic Ocean will become sea-ice free throughout August and September for an additional 800 ±300 Gt of CO2 emissions, while it becomes ice free from July to October for an additional 1400 ±300 Gt of CO2 emissions.}, author = {Stroeve, Julienne C. and Notz, Dirk}, doi = {10.1088/1748-9326/aade56}, issn = {1748-9326}, journal = {Environmental Research Letters}, keywords = {Arctic,climate change,climate modeling,satellite observations,sea ice}, month = {sep}, number = {10}, pages = {103001}, publisher = {Institute of Physics Publishing}, title = {{Changing state of Arctic sea ice across all seasons}}, url = {https://iopscience.iop.org/article/10.1088/1748-9326/aade56}, volume = {13}, year = {2018} } @article{Stuivenvolt-Allen2019, abstract = {Anomalously cold winters with extreme storms strain natural gas (NG) markets due to heightened demand for heating and electricity generation.

Arctic lakes, through their ice cover phenology, are a key indicator of climatic changes that the high-latitude environment is experiencing.

Within the dominant polar-desert environment, small local warmer areas have been identified. These relatively small regions – polar oases – with longer growing seasons and greater biological productivity and diversity are secluded from the surrounding barren polar desert. The ice regimes of 11 lakes located in both polar-desert and polar-oasis environments, with surface areas between 4 and 542 km2, many of unknown bathymetry, were documented. In order to investigate the response of ice cover of lakes in the CAA to climate conditions during recent years, a 15-year time series (1997–2011) of RADARSAT-1/2 ScanSAR Wide Swath, ASAR Wide Swath, and Landsat acquisitions were analyzed. Results show that melt onset occurred earlier for all observed lakes. With the exception of Lower Murray Lake, all lakes experienced earlier summer ice minimum and water-clear-of-ice (WCI) dates, with greater changes being observed for polar-oasis lakes (9–24 days earlier WCI dates for lakes located in polar oases and 2–20 days earlier WCI dates for polar-desert lakes).

Given that the nutrition gained from consuming cached food will almost always be less than consuming it immediately upon capture, the degree of degradation will play a central role in determining the ecological threshold at which caching is no longer profitable. Our framework proposes that the degree of susceptibility among caching species is based primarily on the duration of storage, and the perishability of stored food. We first summarize the degree of susceptibility of 203 vertebrate caching species. Thirty-eight percent (38{\%}) of these species are long-term cachers ({\textgreater}10 days) but only 2{\%} are both long-term cachers and store highly perishable food. We then integrate insights from the fields of applied food science and plant biology to outline potential mechanisms by which climate change may influence food-caching species. Four climatic factors (temperature, number of freeze-thaw events, deep-freeze events and humidity) have been shown to affect the degradation of food consumed by humans and are also expected to influence the quality of perishable food cached in the wild. Temperature and moisture are likely important factors influencing seemingly nonperishable seeds. Although we are able to provide broad classifications for caching species at risk of climate change, an improved understanding of how environmental conditions affect the quality and persistence of cached food may allow us to better predict the impact of changing climatic conditions on the fitness of food-caching animals.}, author = {Sutton, Alex O. and Strickland, Dan and Norris, D.

We find that plant physiological responses to CO2 reduce predictions of future drought stress, and that this reduction is captured by using plant-centric rather than atmosphere-centric metrics from Earth system models (ESMs). The atmosphere-centric Palmer Drought Severity Index predicts future increases in drought stress for more than 70{\%} of global land area. This area drops to 37{\%} with the use of precipitation minus evapotranspiration (P-E), a measure that represents the water flux available to downstream ecosystems and humans. The two metrics yield consistent estimates of increasing stress in regions where precipitation decreases are more robust (southern North America, northeastern South America, and southern Europe). The metrics produce diverging estimates elsewhere, with P-E predicting decreasing stress across temperate Asia and central Africa. The differing sensitivity of drought metrics to radiative and physiological aspects of increasing CO2 partly explains the divergent estimates of future drought reported in recent studies.

The ensembles reproduce fairly well the observed climate zones, although with some notable discrepancies. CORDEX and HIRES provide realistic fine-scale information which enhances that from the coarser-scale CMIP5, especially in the Gulf of Guinea encompassing marked landcover and topography gradients. The late 21st century projections reveal an extension of torrid climates throughoutWest Africa. In addition, the Sahel, predom- inantly semi-arid in present-day conditions, is projected to face moderately persistent future arid climate. Similarly, the Gulf of Guinea shows a tendency in the future to experience highly seasonal semi-arid conditions. Finally, wet and moist regions with an extreme seasonality around orographic zones become less extensive under future climate change. Consequently, West Africa evolves towards increasingly torrid, arid and semi-arid regimes with the recession of moist and wet zones mostly because of the temperature forcing, although precipitation can be locally an important factor. These features are common to all multimodel ensembles, a sign of robustness, with few disagreements in their areal extents, and with more pronounced changes in the higher-resolution RCM projections. Such changes point towards an increased risk of water stress for managed and unmanaged ecosystems, and thus add an element of vulnerability to future anthropogenic climate change for West African water management, ecosystem services and agricultural activities.}, author = {Sylla, Mouhamadou Bamba and Elguindi, Nellie and Giorgi, Filippo and Wisser, Dominik}, doi = {10.1007/s10584-015-1522-z}, issn = {0165-0009}, journal = {Climatic Change}, month = {jan}, number = {1-2}, pages = {241--253}, title = {{Projected robust shift of climate zones over West Africa in response to anthropogenic climate change for the late 21st century}}, url = {http://link.springer.com/10.1007/s10584-015-1522-z}, volume = {134}, year = {2016} } @article{Sylla2018, author = {Sylla, Mouhamadou Bamba and Faye, Aissatou and Giorgi, Filippo and Diedhiou, Arona and Kunstmann, Harald}, doi = {10.1029/2018EF000873}, issn = {23284277}, journal = {Earth's Future}, month = {jul}, number = {7}, pages = {1029--1044}, title = {{Projected Heat Stress Under 1.5 °C and 2 °C Global Warming Scenarios Creates Unprecedented Discomfort for Humans in West Africa}}, url = {http://doi.wiley.com/10.1029/2018EF000873}, volume = {6}, year = {2018} } @incollection{Sylla2016, address = {Cham, Switzerland}, author = {Sylla, Mouhamadou Bamba and Nikiema, Pinghouinde Michel and Gibba, Peter and Kebe, Ibourahima and Klutse, Nana Ama Browne}, booktitle = {Adaptation to Climate Change and Variability in Rural West Africa}, doi = {10.1007/978-3-319-31499-0_3}, editor = {Yaro, Joseph A. and Hesselberg, Jan}, isbn = {978-3-319-31497-6}, pages = {25--40}, publisher = {Springer}, title = {{Climate Change over West Africa: Recent Trends and Future Projections}}, url = {http://link.springer.com/10.1007/978-3-319-31499-0{\_}3}, year = {2016} } @article{Syvitski2007, abstract = {Sediment flux to the coastal zone is conditioned by geomorphic and tectonic influences (basin area and relief), geography (temperature, runoff), geology (lithology, ice cover), and human activities (reservoir trapping, soil erosion). A new model, termed “BQART” in recognition of those factors, accounts for these varied influences. When applied to a database of 488 rivers, the BQART model showed no ensemble over- or underprediction, had a bias of just 3{\%} across six orders of magnitude in observational values, and accounted for 96{\%} of the between-river variation in the long-term (?30 years) sediment load or yield of these rivers. The geographical range of the 488 rivers covers 63{\%} of the global land surface and is highly representative of global geology, climate, and socioeconomic conditions. Based strictly on geological parameters (basin area, relief, lithology, ice erosion), 65{\%} of the between-river sediment load is explained. Climatic factors (precipitation and temperature) account for an additional 14{\%} of the variability in global patterns in load. Anthropogenic factors account for an additional 16{\%} of the between-river loads, although with ever more dams being constructed or decommissioned and socioeconomic conditions and infrastructure in flux, this contribution is temporally variable. The glacial factor currently contributes only 1{\%} of the signal represented by our globally distributed database, but it would be much more important during and just after major glaciations. The BQART model makes possible the quantification of the influencing factors (e.g., climate, basin area, ice cover) within individual basins, to better interpret the terrestrial signal in marine sedimentary records.

However, the intensification of the winds has been the strongest ever observed in the past century, the reason for which is still unclear. Here we show, using multiple climate simulations for 1921-2014 by a global climate model, that approximately one-third of the trade-wind intensification for 1991-2010 can be attributed to changes in sulfate aerosols. The multidecadal sea surface temperature anomaly induced mostly by volcanic aerosols dominates in the western North Pacific, and its sign changed rapidly from negative to positive in the 1990s, coherently with Atlantic multidecadal variability. The western North Pacific warming resulted in intensification of trade winds to the west of the dateline.

Large differences in projected drought changes are observed among different regions.

For the most part, autumn and summer show increases in drying. The largest relative changes in both summer drying and winter wetting were found over northern regions, but the offsetting seasonal effects typically balance out to yield various degrees of wetting on the annual scale for this region.

The aim of this study is to investigate and document the climate change information provided by the CORDEX-CORE simulation ensemble, as a part of the World Climate Research Programme (WCRP) CORDEX community. An overview of the annual and monthly mean climate change information in selected regions in different CORDEX domains is presented for temperature and precipitation, providing the foundation for detailed follow-up studies and applications. Initially, two regional climate models (RCMs), REMO and RegCM were used to downscale global climate model output. The driving simulations by AR5 global climate models (AR5-GCMs) were selected to cover the spread of high, medium, and low equilibrium climate sensitivity at a global scale.

Often, heat waves are accompanied by drought conditions. It is projected that the global land area experiencing heat waves will double by 2020, and quadruple by 2040. Extreme heat events can impact a wide variety of tree functions. At the leaf level, photosynthesis is reduced, photo-oxidative stress increases, leaves abscise, and the growth rate of remaining leaves decreases. In some species, stomatal conductance increases at high temperatures, which may be a mechanism for leaf cooling. At the whole plant level, heat stress can decrease growth and shift biomass allocation. When drought stress accompanies heat waves, the negative effects of heat stress are exacerbated and can lead to tree mortality. However, some species exhibit remarkable tolerance to thermal stress. Responses include changes that minimize stress on photosynthesis and reductions in dark respiration. Although there have been few studies to date, there is evidence of within-species genetic variation in thermal tolerance which could be important to exploit in production forestry systems.

We show that irrigation expansion can explain the negative correlation between global observed changes in daytime summer temperatures and present-day irrigation extent.

Since 1980, almost 1500 such events have been reported in Europe. This study investigates climate change impacts on European floods under 1.5, 2, and 3 K global warming. The impacts are assessed employing a multi-model ensemble containing three hydrologic models (HMs: mHM, Noah-MP, PCR-GLOBWB) forced by five CMIP5 general circulation models (GCMs) under three Representative Concentration Pathways (RCPs 2.6, 6.0, and 8.5). This multi-model ensemble is unprecedented with respect to the combination of its size (45 realisations) and its spatial resolution, which is 5 km over the entirety of Europe. Climate change impacts are quantified for high flows and flood events, represented by 10{\%} exceedance probability and annual maxima of daily streamflow, respectively. The multi-model ensemble points to the Mediterranean region as a hotspot of changes with significant decrements in high flows from −11{\%} at 1.5 K up to −30{\%} at 3 K global warming mainly resulting from reduced precipitation. Small changes ({\textless} ±10{\%}) are observed for river basins in Central Europe and the British Isles under different levels of warming. Projected higher annual precipitation increases high flows in Scandinavia, but reduced snow melt equivalent decreases flood events in this region. Neglecting uncertainties originating from internal climate variability, downscaling technique, and hydrologic model parameters, the contribution by the GCMs to the overall uncertainties of the ensemble is in general higher than that by the HMs. The latter, however, have a substantial share in the Mediterranean and Scandinavia.

We analyzed temperature data from the South Island of New Zealand and investigated whether the hot summer of 2017/18 affected species of bull kelp, Durvillaea antarctica, D. poha, and D. willana. Durvillaea spp. are large iconic seaweeds that inhabit the low intertidal zone of exposed coastlines, where they underpin biodiversity and ecosystem functioning. Sea surface temperatures (SST) during the summer of 2017/18 included the strongest marine heatwaves recorded in 38 years of existing oceanic satellite data for this region. Air temperatures were also high, and, coupled with small wave heights, resulted in strong desiccation stress during daytime low tides. Before-After analysis of drone images of four reef platforms (42, 42, 44, and 45°S) was used to evaluate changes to bull kelp over the hot summer. Bull kelp loss varied among species and reefs, with the greatest (100{\%}) loss of D. poha at Pile Bay in Lyttelton Harbor (44°S). In Pile Bay, SST exceeded 23°C and air temperatures exceeded 30°C, while Durvillaea was exposed for up to 3 h per day during low tide. Follow-up surveys showed that all bull kelps were eliminated from Pile Bay, and from all reefs within and immediately outside of Lyttelton Harbor. Following the localized extinction of bull kelp in Pile Bay, the invasive kelp Undaria pinnatifida recruited in high densities (average of 120 m -2 ). We conclude that bull kelps are likely to experience additional mortalities in the future because heatwaves are predicted to increase in magnitude and durations.

This study aims at assessing future changes in the potential for wind power generation over the whole Europe and in the effective wind power production from national wind farms operating at the end of 2012 and planned by 2020. For this purpose, a simplified wind power generation model is applied to an ensemble of 15 regional climate projections achieved from 10 Regional Climate Models downscaling six Global Climate Models under the SRES A1B emission scenario from the ENSEMBLES project. The use of a relatively large multi-model ensemble allows the identification of robust changes and the estimation of a range of uncertainties associated with projected changes. We show with a high level of confidence that, under the A1B scenario, over most of Europe, changes in wind power potential will remain within ±15 and ±20 {\%} by mid and late century respectively. Overall, we find a tendency toward a decrease of the wind power potential over Mediterranean areas and an increase over Northern Europe. Changes in multi-year power production will not exceed 5 and 15 {\%} in magnitude at the European and national scale respectively for both wind farms in operation at the end of 2012 and planned by 2020.

We compare the impacts for different global warming scenarios: +1.5 °C, +2 °C and +3 °C. Results show that climate change has negative impacts on electricity production in most countries and for most technologies. Such impacts remain limited for a 1.5 °C warming, and roughly double for a 3 °C warming. Impacts are relatively limited for solar photovoltaic and wind power potential which may reduce up to 10{\%}, while hydropower and thermoelectric generation may decrease by up to 20{\%}.

Excess rainfall the year prior to fire occurrence increased fire risk across grasslands, and thus overall fire probability, more so than drought the year that fire occurred.

This study investigates future changes in flood hazard and agricultural production caused by these different scales of human-induced stresses. A quasi- two-dimensional (quasi-2D) hydrodynamic model was used to simulate eight scenarios representing the individual and compound impacts of these drivers for a baseline (1971–2000) and future (2036–2065) period. The scenarios map the most likely future pathway of climate change (RCP 4.5) combined with the best available Mekong upstream hydropower development, and land subsidence scenarios as well as the current delta development plan. We found that sea-level rise and land subsidence would cause the highest changes in flood hazard and damage to rice crop, followed by hydropower and climate change impacts. Expansion of high-dyke areas in two northernmost delta provinces (An Giang and Dong Thap) would have the smallest impact. The combination of all modelled drivers is projected to increase delta inundation extent by 20{\%}, accompanied with prolonging submergence of 1–2 months, and 2–3 times increase in annual flood damage to rice crops in the flood-prone areas of the VMD.

Winter and summer sensitivity responses, and morpho-biochemical acclimation patterns have also been summarized. Sustenance in wheat and rice production is evident but impacts of increasing temperatures are negating this on bio-physiological level impacts. Maize crops are experiencing more impacts on yield as compared to wheat and rice. Fruits and vegetable production is highly vulnerable to climate change at their reproductive stages and also due to more disease prevalence. Fisheries as a critical animal food source; is in extreme danger as apparent changes in their habitat and unmanageable environmental conditions are producing extreme losses.

The concept of C3S ECEM, its methodology and some results are presented here. The first part focuses on the construction of reference data sets for climate variables based on the ERA-Interim reanalysis. Subsequently, energy variables were created by transforming the bias-adjusted climate variables using a combination of statistical and physically-based models. A comprehensive set of measured energy supply and demand data was also collected, in order to assess the robustness of the conversion to energy variables. Climate and energy data have been produced both for the historical period (1979–2016) and for future projections (from 1981 to 2100, to also include a past reference period, but focusing on the 30 year period 2035–2065). The skill of current seasonal forecast systems for climate and energy variables has also been assessed. The C3S ECEM project was designed to provide ample opportunities for stakeholders to convey their needs and expectations, and assist in the development of a suitable Demonstrator. This is the tool that collects the output produced by C3S ECEM and presents it in a user-friendly and interactive format, and it therefore constitutes the essence of the C3S ECEM proof-of-concept climate service.{\textless}/p{\textgreater}{\textless}/p{\textgreater}}, author = {Troccoli, Alberto and Goodess, Clare and Jones, Phil and Penny, Lesley and Dorling, Steve and Harpham, Colin and Dubus, Laurent and Parey, Sylvie and Claudel, Sandra and Khong, Duc-Huy and Bett, Philip E. and Thornton, Hazel and Ranchin, Thierry and Wald, Lucien and Saint-Drenan, Yves-Marie and {De Felice}, Matteo and Brayshaw, David and Suckling, Emma and Percy, Barbara and Blower, Jon}, doi = {10.5194/asr-15-191-2018}, issn = {1992-0636}, journal = {Advances in Science and Research}, month = {aug}, pages = {191--205}, title = {{Creating a proof-of-concept climate service to assess future renewable energy mixes in Europe: An overview of the C3S ECEM project}}, url = {https://www.adv-sci-res.net/15/191/2018/}, volume = {15}, year = {2018} } @article{Troccoli2012, abstract = {Accurate estimates of long-term linear trends of wind speed provide a useful indicator for circulation changes in the atmosphere and are invaluable for the planning and financing of sectors such as wind energy. Here a large number of wind observations over Australia and reanalysis products are analyzed to compute such trends. After a thorough quality control of the observations, it is found that the wind speed trends for 1975–2006 and 1989–2006 over Australia are sensitive to the height of the station: they are largely negative for the 2-m data but are predominantly positive for the 10-m data. The mean relative trend at 2 m is 20.10 6 0.03{\%}yr21 (20.3660.04{\%}yr21) for the 1975–2006 (1989–2006)period,whereas at 10 mit is 0.9060.03{\%}yr21 (0.69 6 0.04{\%} yr21) for the 1975–2006 (1989–2006) period. Also, at 10 m light winds tend to increase more rapidly than the mean winds, whereas strong winds increase less rapidly than the mean winds; at 2 m the trends in both light and strong winds vary in line with the mean winds. It was found that a qualitative link could be established between the observed features in the linear trends and some atmospheric circulation indicators (mean sea level pressure, wind speed at 850 hPa, and geopotential at 850 hPa), particularly for the 10-mobservations. Further, the magnitude of the trend is also sensitive to the period selected, being closer to zero when a very long period, 1948–2006, is considered.

Meteorological blocking events (stable high-pressure systems) have been shown to be one of the factors that trigger cold spells in spring. While current knowledge does not allow for drawing conclusions as to any change in future frequency and duration of blocking episodes due to climate change, the combination of their stable occurrence with the biological system under a warming trend can lead to economic damage increases. To evaluate future frost risk for apple producers in south-eastern Styria, we combine a phenological sequential model with highly resolved climate projections for Austria. Our model projects a mean advance of blooming of –1.6 ± 0.9 days per decade, shifting the bloom onset towards early April by the end of the 21st century. Our findings indicate that overall frost risk for apple cultures will remain in a warmer climate and potentially even increase due to a stronger connection between blocking and cold spells in early spring that can be identified from observational data. To prospectively deal with frost risk, measures are needed that either stabilize crop yields or ensure farmers' income by other means. We identify appropriate adaptation measures and relate their costs to the potential frost risk increase.

Recent studies suggest that extreme heat events will likely increase in frequency, intensity, and duration in coming decades in response to changing climate. OBJECTIVE The overall objective of this study was to investigate if extreme heat events are associated with hay fever. METHODS We linked National Health Interview Survey (NHIS) data from 1997 to 2013 (n = 505,386 respondents) with extreme heat event data, defined as days when daily maximum temperature (TMAX) exceeded the 95th percentile values of TMAX for a 30-year reference period (1960-1989). We used logistic regression to investigate the associations between exposure to annual and seasonal extreme heat events and adult hay fever prevalence among the NHIS respondents. RESULTS During 1997-2013, hay fever prevalence among adults 18 years and older was 8.43{\%}. Age, race/ethnicity, poverty status, education, and sex were significantly associated with hay fever status. We observed that adults in the highest quartile of exposure to extreme heat events had a 7{\%} increased odds of hay fever compared with those in the lowest quartile of exposure (odds ratios: 1.07, 95{\%} confidence interval: 1.02-1.11).

Fire activity in central Chile was mainly associated with above-average precipitation during winter of the previous year and with dry conditions during spring to summer. The later association was particularly strong in the southern, wetter part of the study region. Maximum temperature had a positive significant relationship with burned area across the study region, with stronger correlations toward the south.

This Climate Science Special Report (CSSR) is designed to capture that new information and build on the existing body of science in order to summarize the current state of knowledge and provide the scientific foundation for the Fourth National Climate Assessment (NCA4). Since NCA3, stronger evidence has emerged for continuing, rapid, human-caused warming of the global atmosphere and ocean. This report concludes that “it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century. For the warming over the last century, there is no convincing alternative explanation supported by the extent of the observational evidence.” The last few years have also seen record-breaking, climate-related weather extremes, the three warmest years on record for the globe, and continued decline in arctic sea ice. These trends are expected to continue in the future over climate (multidecadal) timescales. Significant advances have also been made in our understanding of extreme weather events and how they relate to increasing global temperatures and associated climate changes. Since 1980, the cost of extreme events for the United States has exceeded {\$}1.1 trillion; therefore, better understanding of the frequency and severity of these events in the context of a changing climate is warranted. Periodically taking stock of the current state of knowledge about climate change and putting new weather extremes, changes in sea ice, increases in ocean temperatures, and ocean acidification into context ensures that rigorous, scientifically-based information is available to inform dialogue and decisions at every level. This climate science report serves as the climate science foundation of the NCA4 and is generally intended for those who have a technical background in climate science.

We use a global coupled chemistry–climate–land model (CESM) to assess the integrated effect of climate, emissions and land use changes on annual surface O3 and PM2.5 in the United States with a focus on national parks (NPs) and wilderness areas, using the RCP4.5 and RCP8.5 projections. We show that, when stringent domestic emission controls are applied, air quality is predicted to improve across the US, except surface O3 over the western and central US under RCP8.5 conditions, where rising background ozone counteracts domestic emission reductions. Under the RCP4.5 scenario, surface O3 is substantially reduced (about 5 ppb), with daily maximum 8 h averages below the primary US Environmental Protection Agency (EPA) National Ambient Air Quality Standards (NAAQS) of 75 ppb (and even 65 ppb) in all the NPs. PM2.5 is significantly reduced in both scenarios (4 $\mu$g m−3; {\~{}}50{\%}), with levels below the annual US EPA NAAQS of 12 $\mu$g m−3 across all the NPs; visibility is also improved (10–15 dv; {\textgreater}75 km in visibility range), although some western US parks with Class I status (40–74 {\%} of total sites in the US) are still above the 2050 planned target level to reach the goal of natural visibility conditions by 2064. We estimate that climate-driven increases in fire activity may dominate summertime PM2.5 over the western US, potentially offsetting the large PM2.5 reductions from domestic emission controls, and keeping visibility at present-day levels in many parks. Our study indicates that anthropogenic emission patterns will be important for air quality in 2050. However, climate and land use changes alone may lead to a substantial increase in surface O3 (2–3 ppb) with important consequences for O3 air quality and ecosystem degradation at the US NPs. Our study illustrates the need to consider the effects of changes in climate, vegetation, and fires in future air quality management and planning and emission policy making.}, author = {{Val Martin}, M. and Heald, C.

Climate change has the potential to greatly expand fire-prone areas to moist and wet tropical forests and grasslands that have been traditionally less fire-prone, and to extend and create more temporal variability in fire seasons. We built a machine learning random forest classifier to analyze the relationship between climatic, socio-economic, and fire history data with fire occurrence and extent for the years 2003–2011 in Puerto Rico, nearly 35,000 fires. Using classifiers based on climate measurements alone, we found that the climate space is a reliable associate, if not a predictor, of fire occurrence and extent in this environment. We found a strong relationship between occurrence and a change from average weather conditions, and between extent and severity of weather conditions. The probability that the random forest classifiers will rank a positive example higher than a negative example is 0.8–0.89 in the classifiers for deciding if a fire occurs, and 0.64–0.69 in the classifiers for deciding if the fire is greater than 5 ha.

On 19 May 2016 the afternoon temperature reached 51.0 °C in Phalodi in the northwest of India – a new record for the highest observed maximum temperature in India. The previous year, a widely reported very lethal heat wave occurred in the southeast, in Andhra Pradesh and Telangana, killing thousands of people. In both cases it was widely assumed that the probability and severity of heat waves in India are increasing due to global warming, as they do in other parts of the world. However, we do not find positive trends in the highest maximum temperature of the year in most of India since the 1970s (except spurious trends due to missing data). Decadal variability cannot explain this, but both increased air pollution with aerosols blocking sunlight and increased irrigation leading to evaporative cooling have counteracted the effect of greenhouse gases up to now. Current climate models do not represent these processes well and hence cannot be used to attribute heat waves in this area. The health effects of heat are often described better by a combination of temperature and humidity, such as a heat index or wet bulb temperature. Due to the increase in humidity from irrigation and higher sea surface temperatures (SSTs), these indices have increased over the last decades even when extreme temperatures have not. The extreme air pollution also exacerbates the health impacts of heat. From these factors it follows that, from a health impact point of view, the severity of heat waves has increased in India. For the next decades we expect the trend due to global warming to continue but the surface cooling effect of aerosols to diminish as air quality controls are implemented. The expansion of irrigation will likely continue, though at a slower pace, mitigating this trend somewhat. Humidity will probably continue to rise. The combination will result in a strong rise in the temperature of heat waves. The high humidity will make health effects worse, whereas decreased air pollution would decrease the impacts.}, author = {van Oldenborgh, Geert Jan and Philip, Sjoukje and Kew, Sarah and van Weele, Michiel and Uhe, Peter and Otto, Friederike and Singh, Roop and Pai, Indrani and Cullen, Heidi and AchutaRao, Krishna}, doi = {10.5194/nhess-18-365-2018}, issn = {1684-9981}, journal = {Natural Hazards and Earth System Sciences}, month = {jan}, number = {1}, pages = {365--381}, title = {{Extreme heat in India and anthropogenic climate change}}, url = {https://nhess.copernicus.org/articles/18/365/2018/}, volume = {18}, year = {2018} } @article{nhess-2020-69, abstract = {Abstract. Disastrous bushfires during the last months of 2019 and January 2020 affected Australia, raising the question to what extent the risk of these fires was exacerbated by anthropogenic climate change. To answer the question for southeastern Australia, where fires were particularly severe, affecting people and ecosystems, we use a physically based index of fire weather, the Fire Weather Index; long-term observations of heat and drought; and 11 large ensembles of state-of-the-art climate models. We find large trends in the Fire Weather Index in the fifth-generation European Centre for Medium-Range Weather Forecasts (ECMWF) Atmospheric Reanalysis (ERA5) since 1979 and a smaller but significant increase by at least 30 {\%} in the models. Therefore, we find that climate change has induced a higher weather-induced risk of such an extreme fire season. This trend is mainly driven by the increase of temperature extremes. In agreement with previous analyses we find that heat extremes have become more likely by at least a factor of 2 due to the long-term warming trend. However, current climate models overestimate variability and tend to underestimate the long-term trend in these extremes, so the true change in the likelihood of extreme heat could be larger, suggesting that the attribution of the increased fire weather risk is a conservative estimate. We do not find an attributable trend in either extreme annual drought or the driest month of the fire season, September–February. The observations, however, show a weak drying trend in the annual mean. For the 2019/20 season more than half of the July–December drought was driven by record excursions of the Indian Ocean Dipole and Southern Annular Mode, factors which are included in the analysis here. The study reveals the complexity of the 2019/20 bushfire event, with some but not all drivers showing an imprint of anthropogenic climate change.

This resulted in global projections of daily river discharge and water temperature under future climate. Our results show an increase in the seasonality of river discharge (both increase in high flow and decrease in low flow) for about one-third of the global land surface area for 2071-2100 relative to 1971-2000. Global mean and high (95th percentile) river water temperatures are projected to increase on average by 0.8-1.6 (1.0-2.2). °C for the SRES B1-A2 scenario for 2071-2100 relative to 1971-2000. The largest water temperature increases are projected for the United States, Europe, eastern China, and parts of southern Africa and Australia. In these regions, the sensitivities are exacerbated by projected decreases in low flows (resulting in a reduced thermal capacity). For strongly seasonal rivers with highest water temperatures during the low flow period, up to 26{\%} of the increases in high (95th percentile) water temperature can be attributed indirectly to low flow changes, and the largest fraction is attributable directly to increased atmospheric energy input. A combination of large increases in river temperature and decreases in low flows are projected for the southeastern United States, Europe, eastern China, southern Africa and southern Australia. These regions could potentially be affected by increased deterioration of water quality and freshwater habitats, and reduced water available for human uses such as thermoelectric power and drinking water production. {\textcopyright} 2012 Elsevier Ltd.}, author = {van Vliet, Michelle T.H. and Franssen, Wietse H.P. and Yearsley, John R. and Ludwig, Fulco and Haddeland, Ingjerd and Lettenmaier, Dennis P. and Kabat, Pavel}, doi = {10.1016/j.gloenvcha.2012.11.002}, isbn = {0959-3780}, issn = {09593780}, journal = {Global Environmental Change}, month = {apr}, number = {2}, pages = {450--464}, title = {{Global river discharge and water temperature under climate change}}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0959378012001331}, volume = {23}, year = {2013} } @article{Vanderlinden2017, abstract = {ABSTRACT Vanderlinden, J.-P.; Baztan, J.; Touili, N.; Kane, I.O.; Rulleau, B.; Diaz Simal, P.; Pietrantoni, L.; Prati, G., and Zagonari, F., 2017.

This mismatch leads to projections of future heat-related mortality, survivability, and liveability that are not realistic or robust. Oversimplification of these complex responses, such as assuming that a single temperature value adequately predicts death, or using inappropriate heat stress metrics, can result in unrealistic projections of the range of future heat-related health outcomes, from well-being to illness to death. Discounting human adaptive capacity introduces further uncertainties. Consequently , decision-makers may be poorly informed about evolving heat-related risks, potentially resulting in under-preparation or over-spending of scarce health system resources. Given the global threat of heat to human health, productivity, and well-being, there is an urgent need to provide more robust and realistic projections of future heat-related health risks to assess both survivability and liveability in a warming world. This assessment requires combining knowledge from climate science, physiology, and epidemiology. Modeling advancements that accurately characterize the range of human responses to extreme heat can provide more robust climate impact assessments to enhance policy decisions and interventions that protect the most vulnerable people from current and future impacts of extreme heat. Cascade of factors leading to heat stress, strain, and adverse health outcomes Heat stress is defined by the net heat load imposed on a person from the combined thermal effects of the environment (air temperature, radiant temperature, humidity, and wind), activity (metabolic heat production), and clothing.

This review focuses on the impacts of climate change factors on the growth of weeds and the potential variations in the efficacy of herbicides under changing climate conditions. Weeds are likely to show greater resilience and better adaptation to changes in CO2 concentrations and rising temperature in competition with crops due to their diverse gene pool and greater physiological plasticity. Weeds with C3 and C4 photosynthetic pathways may exhibit differential responses to higher CO2 levels and temperatures, which can affect the dynamics of crop–weed competition. In addition to its positive impact on weed growth, climate change factors could influence the efficacy of many herbicides, making weed management a major challenge for sustainable crop production. To enhance our understanding of the impact of climate change factors on herbicide efficacy, it is important to evaluate the effects of environmental conditions on various herbicide modes of action. Environmental factors such as CO2, light, temperature, relative humidity, and soil moisture differentially affect the uptake, translocation, and activity of different herbicide chemistries. Furthermore, interactions among these environmental factors may have unpredictable effects on herbicide activity. Existing literature suggests that climate change factors impacts vary not only within herbicide modes of action but also among herbicides belonging to same mode of action, so making generalized assumptions for each mode of action is difficult. Extensive research on the impact of climate change factors and their interactions on all commonly used herbicides is necessary to understand the implications for weed management in future climate scenarios.}, author = {Varanasi, Aruna and Prasad, P.V.

This paper reviews 66 studies that have evaluated outcomes and/or impacts of agricultural WCS in Africa, highlighting areas that have received relatively more attention as well as persistent gaps. While the evaluation of WCS outcomes is relatively straightforward, estimates of the number of people who access and use these services are uneven (covering a small number of communities in 23 of 54 African countries) and highly variable (with access estimates ranging from {\~{}}2 to 86{\%}, depending on the service and the population). Meanwhile, 22 documents estimate the impact of WCS with respect to yields and/or income. Developed with a variety of methods, these estimates are also wide ranging and illustrate how impact is conditioned on a number of characteristics of the service, the user, and the context in which both operate. The paper uses lessons developed through this review to develop a ?learning agenda,? or evidence-building roadmap, to establish priorities that can guide work to improve the design, delivery, and impact of agricultural WCS in Africa. Priority learning areas include activities that can strengthen the evidence of access, use, and impacts of WCS, along with those that can advance the use and usability of evidence so as to improve the design and targeting of WCS services.

Understanding how fire weather danger indices changed in the past and how such changes affected forest fire activity is important in a changing climate.

Additionally, we used national forest fire statistics from Greece, Spain and Finland to examine the relationship between fire danger and fires. There is no obvious trend in fire danger for the time period covered by ERA-40 (1960–1999), whereas for the period 1980–2012 covered by ERA Interim, the mean FWI shows an increasing trend for southern and eastern Europe which is significant at the 99{\%} confidence level. The cross correlations calculated at the national level in Greece, Spain and Finland between total area burned and mean FWI of the current season is of the order of 0.6, demonstrating the extent to which the current fire-season weather can explain forest fires.

This paper proposes a methodology for estimating the transient probability distribution of yearly hydrological variables conditional to an ensemble of projections built from multiple general circulation models (GCMs), multiple statistical downscaling methods (SDMs), and multiple hydrological models (HMs). The methodology is based on the quasi-ergodic analysis of variance (QE-ANOVA) framework that allows quantifying the contributions of the different sources of total uncertainty, by critically taking account of large-scale internal variability stemming from the transient evolution of multiple GCM runs, and of small-scale internal variability derived from multiple realizations of stochastic SDMs. This framework thus allows deriving a hierarchy of climate and hydrological uncertainties, which depends on the time horizon considered. It was initially developed for long-term climate averages and is here extended jointly to (1) yearly anomalies and (2) low-flow variables. It is applied to better understand possible transient futures of both winter and summer low flows for two snow-influenced catchments in the southern French Alps. The analysis takes advantage of a very large data set of transient hydrological projections that combines in a comprehensive way 11 runs from four different GCMs, three SDMs with 10 stochastic realizations each, as well as six diverse HMs. The change signal is a decrease in yearly low flows of around −20 {\%} in 2065, except for the more elevated catchment in winter where low flows barely decrease. This signal is largely masked by both large- and small-scale internal variability, even in 2065. The time of emergence of the change signal is however detected for low-flow averages over 30-year time slices starting as early as 2020. The most striking result is that a large part of the total uncertainty – and a higher one than that due to the GCMs – stems from the difference in HM responses. An analysis of the origin of this substantial divergence in HM responses for both catchments and in both seasons suggests that both evapotranspiration and snowpack components of HMs should be carefully checked for their robustness in a changed climate in order to provide reliable outputs for informing water resource adaptation strategies.}, author = {Vidal, Jean-Philippe and Hingray, Beno{\^{i}}t and Magand, Claire and Sauquet, Eric and Ducharne, Agn{\`{e}}s}, doi = {10.5194/hess-20-3651-2016}, issn = {1607-7938}, journal = {Hydrology and Earth System Sciences}, month = {sep}, number = {9}, pages = {3651--3672}, publisher = {Copernicus GmbH}, title = {{Hierarchy of climate and hydrological uncertainties in transient low-flow projections}}, url = {https://hess.copernicus.org/articles/20/3651/2016/}, volume = {20}, year = {2016} } @article{Vikhamar-Schuler2016, abstract = {In recent years extreme winter warming events have been reported in arctic areas.

Snow and ice provide large amounts of meltwater to the Indus, Ganges and Brahmaputra rivers. This study combines present-day observations and reanalysis data with climate model projections to estimate the amount of snow falling over the basins today and in the last decades of the 21st century. Estimates of present-day snowfall based on a combination of temperature and precipitation from reanalysis data and observations vary by factors of 2–4. The spread is large, not just between the reanalysis and the observations but also between the different observational data sets. With the strongest anthropogenic forcing scenario (RCP8.5), the climate models project reductions in annual snowfall by 30–50{\%} in the Indus Basin, 50–60{\%} in the Ganges Basin and 50–70{\%} in the Brahmaputra Basin by 2071–2100. The reduction is due to increasing temperatures, as the mean of the models show constant or increasing precipitation throughout the year in most of the region. With the strongest anthropogenic forcing scenario, the mean elevation where rain changes to snow – the rain/snow line – creeps upward by 400–900 m, in most of the region by 700–900 meters. The largest relative change in snowfall is seen in the upper westernmost sub-basins of the Brahmaputra. With the strongest forcing scenario, most of this region will have temperatures above freezing, especially in the summer. The projected reduction in annual snowfall is 65–75{\%}. In the upper Indus, the effect of a warmer climate on snowfall is less extreme, as most of the terrain is high enough to have temperatures sufficiently far below freezing today.

Large amplitude fluctuations in the frequency and intensity of tropical cyclones greatly complicate both the detection of long-term trends and their attribution to rising levels of atmospheric greenhouse gases. Trend detection is further impeded by substantial limitations in the availability and quality of global historical records of tropical cyclones. Therefore, it remains uncertain whether past changes in tropical cyclone activity have exceeded the variability expected from natural causes. However, future projections based on theory and high-resolution dynamical models consistently indicate that greenhouse warming will cause the globally averaged intensity of tropical cyclones to shift towards stronger storms, with intensity increases of 2–11{\%} by 2100. Existing modelling studies also consistently project decreases in the globally averaged frequency of tropical cyclones, by 6–34{\%}. Balanced against this, higher resolution modelling studies typically project substantial increases in the frequency of the most intense cyclones, and increases of the order of 20{\%} in the precipitation rate within 100 km of the storm centre.

Climate warming and related drivers of soil thermal change are expected to modify the distribution of permafrost, leading to changing hydrologic conditions, including alterations in soil moisture, connectivity of inland waters, streamflow seasonality, and the partitioning of water stored above and below ground. The field of permafrost hydrology is undergoing rapid advancement with respect to multiscale observations, subsurface characterization, modeling, and integration with other disciplines. However, gaining predictive capability of the many interrelated consequences of climate change is a persistent challenge due to several factors. Observations of hydrologic change have been causally linked to permafrost thaw, but applications of process-based models needed to support and enhance the transferability of empirical linkages have often been restricted to generalized representations. Limitations stem from inadequate baseline permafrost and unfrozen hydrogeologic characterization, lack of historical data, and simplifications in structure and process representation needed to counter the high computational demands of cryohydrogeologic simulations. Further, due in part to the large degree of subsurface heterogeneity of permafrost landscapes and the nonuniformity in thaw patterns and rates, associations between various modes of permafrost thaw and hydrologic change are not readily scalable; even trajectories of change can differ.

The global hydrological and water resources model PCR-GLOBWB is used to simulate daily discharge globally at 0.5° resolution for 1971–2099. The model was forced with the latest CMIP5 climate projections taken from five General Circulation Models (GCMs) and four emission scenarios (RCPs), under the framework of the Inter-Sectoral Impact Model Intercomparison Project. A natural or pristine scenario has been used to calculate the impact of the changing climate on hydrological drought and has been compared to a scenario with human influences. In the latter scenario reservoir operations and human water use are included in the simulations of discharge for the 21st century. The impact of humans on the low flow regime and hydrological drought characteristics has been studied at a catchment scale. Results show a significant impact of climate change and human water use in large parts of Asia, Middle East and the Mediterranean, where the relative contribution of humans on the changed drought severity can be close to 100{\%}. The differences between Representative Concentration Pathways are small indicating that human water use is proportional to the changes in the climate. Reservoirs tend to reduce the impact of drought by water retention in the wet season, which in turn will lead to increased water availability in the dry season, especially for large regions in Europe and North America. The impact of climate change varies throughout the season for parts of Europe and North-America, while in other regions (e.g. North-Africa, Middle East and Mediterranean), the impact is not influenced by seasonal changes. This study illustrates that the impact of human water use and reservoirs is nontrivial and can vary substantially per region and per season.

As a consequence of warmer average temperatures, wheat flowering occurred earlier, but the probability of heat stress around flowering still increased by about 3.8{\%}–6.2{\%}. Simulated potential yield across six sites increased on average by about 2.5{\%} regardless of the emission scenario. However, simulated water-limited yield tended to decline at wet and cool locations under future climate while increased at warm and dry locations. Soils with higher plant available water capacity (PAWC) showed a lower response of water-limited yield to rainfall changes except at very dry sites, which means soils with high PAWC were less affected by rainfall changes compared with soils with low PAWC. Our results also indicated that a drought stress index decreased with increasing PAWC and then stagnated at high PAWC. Under high emission scenario RCP8.5, drought stress was expected to decline or stay about the same due to elevated CO2 compensation effect.

How coastal upwelling regimes might change in a warming climate is therefore a question of vital importance. Although enhanced land-ocean differential heating due to greenhouse warming has been proposed to intensify coastal upwelling by strengthening alongshore winds, analyses of observations and previous climate models have provided little consensus on historical and projected trends in coastal upwelling. Here we show that there are strong and consistent changes in the timing, intensity and spatial heterogeneity of coastal upwelling in response to future warming in most Eastern Boundary Upwelling Systems (EBUSs). An ensemble of climate models shows that by the end of the twenty-first century the upwelling season will start earlier, end later and become more intense at high but not low latitudes. This projected increase in upwelling intensity and duration at high latitudes will result in a substantial reduction of the existing latitudinal variation in coastal upwelling. These patterns are consistent across three of the four EBUSs (Canary, Benguela and Humboldt, but not California). The lack of upwelling intensification and greater uncertainty associated with the California EBUS may reflect regional controls associated with the atmospheric response to climate change.

Considering risk as a function of both heat vulnerability and hazard intensity, this study examines whether poor urban dwellers residing in slums are exposed to higher temperature, adding to their vulnerable demographic and health conditions. Instead of being restricted by sampling size of pixels or other land surface zones, this study follows the intrinsic latent patterns of the heat phenomenon to examine the association between small clusters of slums and heat patterns. Remotely sensed land surface temperature (LST) datasets of moderate resolution are employed to derive the morphological features of the temperature patterns in the city of Ahmedabad, India at the local scale. The optimal representations of temperature pattern morphology are learnt automatically from temporally adjacent images without manually choosing model hyper-parameters. The morphological features are then evaluated to identify the local scale temperature pattern at slum locations. Results show that in particular locations with slums are exposed to a locally high temperature. More specifically, larger slums tend to be exposed to a more intense locally high temperature compared to smaller slums. Due to the small size of slums in Ahmedabad, it is hard to conclude whether slums are impacting the locally high temperature, or slums are more likely to be located in poorly built places already with a locally high temperature. This study complements the missing dimension of hazard investigation to heat-related risk analysis of slums. The study developed a workflow of exploring the temperature patterns at the local scale and examination of heat exposure of slums. It extends the conventional city scale urban temperature analysis into local scales and introduces morphological measurements as new parameters to quantify temperature patterns at a more detailed level.}, author = {Wang, Jiong and Kuffer, Monika and Sliuzas, Richard and Kohli, Divyani}, doi = {10.1016/j.scitotenv.2018.09.324}, issn = {0048-9697}, journal = {Science of The Total Environment}, keywords = {Ahmedabad,India,LST,Local scale,MODIS,Morphological patterns,Slums}, pages = {1805--1817}, title = {{The exposure of slums to high temperature: Morphology-based local scale thermal patterns}}, url = {http://www.sciencedirect.com/science/article/pii/S0048969718337811}, volume = {650}, year = {2019} } @article{Wang2018e, abstract = {Urbanization has led to an obvious urban heat island (UHI) effect in the Yangtze River Delta (YRD), China.

In this study, the temporal and spatial relationship between UHI and O3 in the YRD during 2015 was investigated. The influence factors of UHI effect and O3 are both natural and artificial. Multi-source remote sensing data, which include land cover, land surface temperature (LST), Normalization Difference Vegetation Index (NDVI), and digital elevation model (DEM) data, were used to extract surface landscape elements. The results showed that: (1) the average hourly O3 concentration was 61.83 $\mu$g/m3 (30.92 ppb), the highest value was 105.32 $\mu$g/m3 (52.66 ppb) at 15:00 and the O3 peak was 82.50 $\mu$g/m3 (41.25 ppb) in September. The O3 concentrations and temperature have a similar variation trend both in diurnal and monthly. The O3 concentrations in coastal stations are higher than those inland.

Due in large part to the difficulties in obtaining future daily fire weather projections, one of the major challenges in predicting future fire activity is to estimate how much of the change in weather potential could translate into on-the-ground fire spread. As a result, past studies have used monthly, annual, or multi-decadal weather projections to predict future fires, thereby sacrificing information relevant to day-to-day fire spread. Using climate projections from the fifth phase of the Coupled Model Intercomparison Project (CMIP5), historical weather observations, MODIS fire detection data, and the national fire database of Canada, this study investigated potential changes in the number of active burning days of wildfires by relating 'spread days' to patterns of daily fire-conducive weather. Results suggest that climate change over the next century may have significant impacts on fire spread days in almost all parts of Canada's forested landmass; the number of fire spread days could experience a 2-to-3-fold increase under a high CO2 forcing scenario in eastern Canada, and a greater than 50{\%} increase in western Canada, where the fire potential is already high.

Changes in 20 year return values are estimated from the most suitable GEV distribution chosen from a GEV tree. Twenty year return values of extreme low minimum temperature are found to have warmed strongly over the century in most parts of the continent. There is also a tendency toward warming of extreme high maximum temperatures, but it is weaker than that for minimum temperatures, with the majority of stations not showing significant trends. The observed changes in extreme temperatures are broadly consistent with observed changes in mean temperatures and in the frequency of temperatures above the ninetieth and below the tenth percentile (i.e., extreme indices). The GEV tree analysis provides insight into behavior of extremes with re-occurrence times of several years to decades that are of importance to engineering design/applications, while extreme indices represent moderately extreme events with re-occurrence times of a year or shorter.

Record summer warmth in 2011 and 2012 promoted rapid RTS initialization, increasing active slumps from 100 in a given year or less to over 200 regionally and promoting RTS initiation in previously unaffected terrain. Differential GPS and remote sensing observations of 12 RTSs initiated during this period (2011-2018) provided a mean headwall retreat rate for all RTSs of 6.2 m yr-1 and for specific RTSs up to 26.7 m yr-1. To better understand the dynamics of climate and terrain factors controlling RTS headwall retreat rates we explored RTS interactions by correlating headwall retreat with climate factors (thawing degree days, annual rainfall and annual snowfall) and terrain factors (aspect and slope). Our findings indicate a sensitivity of cold permafrost in the high Arctic to climate-driven thermokarst initiation, but the decoupling of RTS dynamics from climate appears to occur over time for individual RTS as terrain factors take on a greater role controlling headwall retreat.

In Australia, as in many other parts of the world, flood magnitudes are mostly decreasing, despite increasing rainfall extremes. Here, we show how changes in soil moisture have led to decreasing flood magnitudes while rainfall extremes have been increasing. Using gauged streamflow, catchment average rainfall, and modelled soil moisture data across Australia we confirm that streamflow peaks (or floods) that occur at least once a year are strongly related to both the peak rainfall causing the flood and the antecedent soil moisture conditions preceding the storm event. Regions where the magnitude of the peak flow has decreased are visually and statistically correlated to regions of decreasing soil moisture. Flood magnitudes are more likely to increase only for the rarest events, with increases in rainfall offset by decreases in soil moisture for more frequent events. A recurrence interval dependent tipping point is identified beyond which trends in catchment rainfall outweigh those of soil moisture trends and dominate the flood response. For regions where soil moisture has decreased, this tipping point occurs at an average recurrence interval of ten years or more. As most studies investigating trends in flooding generally use annual maxima, changes in soil moisture are likely to be the dominant mechanism behind observed flood trends.

Here we: 1) critically review indicators of wind erosion and blowing dust that are currently available to practitioners; and 2) describe approaches for establishing benchmarks to support wind erosion assessments and management.

Indicators need to be related to the causal soil and vegetation controls in eroding areas to directly inform management. There is great potential to use regional standardized soil and vegetation monitoring datasets, remote sensing and models to provide new information on wind erosion across landscapes.

Most analyses relate to Great Britain, but reference is made to the more extreme recorded events in Ireland. The most intense hailstorm in these Islands reached intensity H8 on the TORRO international scale which extends from intensities H0 to H10. For the 75 years 1930 to 2004 this paper examines significant, damaging (H2 or more intensity) storms in respect of seasonal frequency and geographical distribution. This paper also discusses the climatology (including diurnal incidence) of the less common, but potentially devastating storms of H5 intensity or more, using the much longer period 1800 to 2004 and with particular attention to hail swath lengths and widths. The synoptic origins for these major events, where known, are discussed, with particular reference to Lamb's classification of weather types across the British Isles from 1861 onwards. More than 2500 British and Irish hailstorms are recorded in TORRO's database of which over 1300 are of hailstorm intensity H2 or more, including 156 British storms since 1800 that reached intensity H4–5 or more on the TORRO H scale. The geographical distribution of hailstorms in the British Isles shows that the highest frequency of significant, damaging storms (H2 or more intensity with hailstones usually over 15 mm diameter) is in central and eastern England, with the East Midlands, East Anglia and the lower Thames Valley most conspicuous when the incidences are mapped. Since 1870 the severest (H5 intensity or greater) events have been predominantly associated with cyclonic, southerly or south-easterly weather types; however a significant minority (19{\%}) occurred with an anticyclonic element in the classification.

Using historical aerial photography and satellite images this study presents the first quantitative analysis of physical changes in 27 atoll islands in the central Pacific over a 19 to 61yr period. This period of analysis corresponds with instrumental records that show a rate of sea-level rise of 2.0mm yr−1 in the Pacific. Results show that 86{\%} of islands remained stable (43{\%}) or increased in area (43{\%}) over the timeframe of analysis. Largest decadal rates of increase in island area range between 0.1 to 5.6ha. Only 14{\%} of study islands exhibited a net reduction in island area. Despite small net changes in area, islands exhibited larger gross changes. This was expressed as changes in the planform configuration and position of islands on reef platforms. Modes of island change included: ocean shoreline displacement toward the lagoon; lagoon shoreline progradation; and, extension of the ends of elongate islands. Collectively these adjustments represent net lagoonward migration of islands in 65{\%} of cases. Results contradict existing paradigms of island response and have significant implications for the consideration of island stability under ongoing sea-level rise in the central Pacific. First, islands are geomorphologically persistent features on atoll reef platforms and can increase in island area despite sea-level change. Second, islands are dynamic landforms that undergo a range of physical adjustments in responses to changing boundary conditions, of which sea level is just one factor. Third, erosion of island shorelines must be reconsidered in the context of physical adjustments of the entire island shoreline as erosion may be balanced by progradation on other sectors of shorelines. Results indicate that the style and magnitude of geomorphic change will vary between islands. Therefore, island nations must place a high priority on resolving the precise styles and rates of change that will occur over the next century and reconsider the implications for adaption.}, author = {Webb, Arthur P. and Kench, Paul S.}, doi = {10.1016/j.gloplacha.2010.05.003}, issn = {09218181}, journal = {Global and Planetary Change}, month = {jun}, number = {3}, pages = {234--246}, publisher = {Elsevier}, title = {{The dynamic response of reef islands to sea-level rise: Evidence from multi-decadal analysis of island change in the Central Pacific}}, url = {https://www.sciencedirect.com/science/article/pii/S0921818110001013?via{\%}3Dihub https://linkinghub.elsevier.com/retrieve/pii/S0921818110001013}, volume = {72}, year = {2010} } @article{Webber2017b, abstract = {This article examines the increasing emphasis amongst climate scientists and development professionals on providing ‘climate services' in order to inform adaptation decisions in vulnerable countries.

The SEI has been shown previously to accurately represent the impact of coastal storms at a number of other sites (Miller and Livermont, 2008). When reanalyzed with the SEI, Tropical Storm Debby was found to be more significant in terms of beach erosion potential than any other storm in the record (since 1996), ranking as a “Category 5” storm with a return period of 23.4 years. Hurricane Isaac, which followed closely on the heels of Debby, ranked as a “Category 2” storm with an associated return period of 3 years. A sensitivity analysis performed on the results indicated that the wave steepness threshold used to separate erosion and accretion was particularly important during Isaac, as the conditions throughout the storm remained close to the threshold. While Hurricane Sandy is more known for the devastation it caused in the northeast, it also caused significant beach erosion in the State of Florida. The SEI more accurately reflects the significance of the beach erosion experienced during Sandy, and ranks the storm ahead of all of the other storms in the record (since 1994), including Hurricanes Frances, Gordon, and Jeanne which all made landfall near the area considered.

For example, increased atmospheric CO2 induces a net air-to-sea flux where the oceans take up large amounts of atmospheric CO2 (i.e., ocean acidification [2-5]). Research on ocean acidification is ongoing, and studies have demonstrated the consequences for ecosystems and organismal biology with major impacts on marine food webs, nutrient cycles, overall productivity, and biodiversity [6-9]. Yet, surprisingly little is known about the impact of anthropogenically caused CO2 on freshwater systems due to their more complex biogeochemistry. The current consensus, yet lacking data evidence, is that anthropogenic CO2 does indeed affect freshwater carbon hydrogeochemistry, causing increased pCO2 in freshwater bodies [10-13]. We analyzed long-term data from four freshwater reservoirs and observed a continuous pCO2 increase associated with a decrease in pH, indicating that not only the oceans but also inland waters are accumulating CO2. We tested the effect of pCO2-dependent freshwater acidification using the cosmopolite crustacean Daphnia. For general validity, control pCO2-levels were based on the present global pCO2 average. Treatments were selected with very high pCO2 levels, assuming a continuous non-linear increase of pCO2, reflecting worst-case-scenario future pCO2 levels. Such levels of elevated pCO2 reduced the ability of Daphnia to sense its predators and form adequate inducible defenses. We furthermore determined that pCO2 and not the resulting reduction in pH impairs predator perception. If pCO2 alters chemical communication between freshwater species, this perturbs intra- and interspecific information transfer, which may affect all trophic levels.}, author = {Weiss, Linda C and P{\"{o}}tter, Leonie and Steiger, Annika and Kruppert, Sebastian and Frost, Uwe and Tollrian, Ralph}, doi = {10.1016/j.cub.2017.12.022}, issn = {09609822}, journal = {Current Biology}, keywords = {Chaoborus,Daphnia longicephala,Daphnia pulex,Notonecta,climate change,freshwater acidification,inducible defenses,pCO(2),pH,phenotypic plasticity}, month = {jan}, number = {2}, pages = {327--332.e3}, pmid = {29337079}, publisher = {Elsevier}, title = {{Rising pCO2 in Freshwater Ecosystems Has the Potential to Negatively Affect Predator-Induced Defenses in Daphnia}}, url = {https://linkinghub.elsevier.com/retrieve/pii/S096098221731655X}, volume = {28}, year = {2018} } @article{Weisse2015, abstract = {The term ``climate services'' is commonly used to refer to the generation of climate information, their transformation according to user needs and the subsequent use of the information in decision making processes.

Future climate change is likely to affect proximal and distal (upstream) risk factors for a wide range of health outcomes, but only some of these causal pathways can be modelled using currently available methods and at the global level. This assessment uses scenarios to estimate the effect of climate change on selected health outcomes in the context of uncertain climate and global health futures. Future cause-specific mortality in 2030 and 2050 (in the absence of climate change) was estimated using regression methods for three development futures: base case, high growth and no growth scenarios. Global climate-health models were developed for a range of health outcomes known to be sensitive to climate change: heat-related mortality in elderly people, mortality associated with coastal flooding, mortality associated with diarrhoeal disease in children aged under 15 years, malaria population at risk and mortality, dengue population at risk and mortality, undernutrition (stunting) and associated mortality. Future climate change was characterized by a medium-high emissions scenario (A1b) run through three climate models. The counterfactual was a future world with population growth and economic development but with baseline (1961–1990) climate. The annual burden of mortality due to climate change was estimated for world regions. For most pathways considered, the results reflect both positive and negative impacts on health. Model uncertainty was assessed for each outcome, as far as technically possible. Compared with a future without climate change, the following additional deaths are projected for the year 2030: 38 000 due to heat exposure in elderly people, 48 000 due to diarrhoea, 60 000 due to malaria, and 95 000 due to childhood undernutrition. The World Health Organization (WHO) projects a dramatic decline in child mortality, and this is reflected in declining climate change impacts from child malnutrition and diarrhoeal disease between 2030 and 2050. On the other hand, by the 2050s, deaths related to heat exposure (over 100 000 per year) are projected to increase. Impacts are greatest under a low economic growth scenario because of higher rates of mortality projected in low- and middle-income countries. By 2050, impacts of climate change on mortality are projected to be greatest in south Asia. These results indicate that climate change will have a significant impact on child health by the 2030s. Under a base case socioeconomic scenario, we estimate approximately 250 000 additional deaths due to climate change per year between 2030 and 2050. These numbers do not represent a prediction of the overall impacts of climate change on health, since we could not quantify several important causal pathways.

An original methodology is proposed for comparing GEV models and selecting the best for use. The stationary GEV is rejected for all stations, demonstrating the significant non-stationarity of extreme discharge values in West Africa over the past six decades. The model of best fit most commonly selected is a double-linear model for the central tendency parameter ($\mu$), with the dispersion parameter ($\sigma$) modeled as either stationary, linear, or a double-linear. Change points in double-linear models are relatively consistent for the Senegal basin, with stations switching from a decreasing streamflow trend to an increasing streamflow trend in the early 1980s. In the Niger basin the trend in $\mu$ is generally positive since the 1970s with an increase in slope after the change point, but the change point location is less consistent. The recent increasing trends in extreme discharges are reflected in an especially marked increase in return level magnitudes since the 1980s in the studied Sahelian rivers. The rate of the increase indicated by the study results raises urgent considerations for stakeholders and engineers who are in charge of river basin management and hydraulic works sizing.}, author = {Wilcox, Catherine and Vischel, Th{\'{e}}o and Panthou, G{\'{e}}r{\'{e}}my and Bodian, Ansoumana and Blanchet, Juliette and Descroix, Luc and Quantin, Guillaume and Cass{\'{e}}, Claire and Tanimoun, Bachir and Kone, Soungalo}, doi = {https://doi.org/10.1016/j.jhydrol.2018.07.063}, issn = {0022-1694}, journal = {Journal of Hydrology}, keywords = {Extreme values,Flood hazard,Floods,Model selection,Non-stationarity,West Africa}, pages = {531--545}, title = {{Trends in hydrological extremes in the Senegal and Niger Rivers}}, url = {http://www.sciencedirect.com/science/article/pii/S0022169418305766}, volume = {566}, year = {2018} } @article{Wilcox2016, author = {Wilcox, Andrew C. and Escauriaza, Cristian and Agredano, Roberto and Mignot, Emmanuel and Zuazo, Vicente and Ot{\'{a}}rola, Sebasti{\'{a}}n and Castro, Lina and Giron{\'{a}}s, Jorge and Cienfuegos, Rodrigo and Mao, Luca}, doi = {10.1002/2016GL069751}, issn = {00948276}, journal = {Geophysical Research Letters}, month = {aug}, number = {15}, pages = {8035--8043}, title = {{An integrated analysis of the March 2015 Atacama floods}}, url = {http://doi.wiley.com/10.1002/2016GL069751}, volume = {43}, year = {2016} } @inproceedings{Wild2017a, author = {Wild, Martin and Folini, Doris and Henschel, Florian}, booktitle = {AIP Conference Proceedings}, doi = {10.1063/1.4975562}, isbn = {0735414785}, number = {1}, pages = {100007}, publisher = {AIP Publishing}, title = {{Impact of climate change on future concentrated solar power (CSP) production}}, url = {http://aip.scitation.org/doi/abs/10.1063/1.4975562}, volume = {1810}, year = {2017} } @article{Wild2015, abstract = {Traditionally, for the planning and assessment of solar energy systems, the amount of solar radiation (sunlight) incident on the Earth's surface is assumed to be constant over the years. However, with changing climate and air pollution levels, solar resources may no longer be stable over time and undergo substantial decadal changes. Observational records covering the past decades confirm long-term changes in this quantity. Here we examine how the latest generation of climate models used for the 5th IPCC report projects potential changes in surface solar radiation over the coming decades, and how this may affect, in combination with the expected greenhouse warming, solar power output from photovoltaic (PV) systems. For this purpose, projections up to the mid 21st century from 39 state of the art climate models from the Coupled Model Intercomparison Project Phase 5 (CMIP5) are analysed globally and for selected key regions with major solar power production capacity. The large model ensemble allows to assess the degree of consistency of their projections. Models are largely consistent in the sign of the projected changes in solar radiation under cloud-free conditions as well as surface temperatures over most of the globe, while still reasonably consistent over a considerable part of the globe in the sign of changes in cloudiness and associated changes in solar radiation. A first order estimate of the impact of solar radiation and temperature changes on energy yields of PV systems under the RPC8.5 scenario indicates statistically significant decreases in PV outputs in large parts of the world, but notable exceptions with positive trends in large parts of Europe, South-East of North America and the South-East of China.

Linear trend analysis of comprehensively validated annual downscaled North American Regional Reanalysis (NARR) gridded surface air temperatures for the years 1979–2016 indicates a warming rate of 0.028°C a −1 between 5500 and 6000 m above mean sea level (MSL), which is {\~{}}1.6 times larger than the global-average warming rate between 1970 and 2015.

EDW in the St. Elias region therefore appears to be driven by recent warming of the free troposphere. MODIS satellite data show no evidence for an enhanced snow albedo feedback above 2500 m MSL, and declining trends in sulfate aerosols deposited in high-elevation ice cores suggest a modest increase in radiative forcing at these elevations. In contrast, increasing trends in water vapor mixing ratio at the 500-hPa level measured by radiosonde suggest that a longwave radiation vapor feedback is contributing to EDW.}, author = {Williamson, Scott N and Zdanowicz, Christian and Anslow, Faron S and Clarke, Garry K C and Copland, Luke and Danby, Ryan K and Flowers, Gwenn E and Holdsworth, Gerald and Jarosch, Alexander H and Hik, David S}, doi = {10.1175/JCLI-D-19-0405.1}, issn = {0894-8755}, journal = {Journal of Climate}, month = {apr}, number = {8}, pages = {3253--3269}, publisher = {American Meteorological Society}, title = {{Evidence for Elevation-Dependent Warming in the St. Elias Mountains, Yukon, Canada}}, url = {http://journals.ametsoc.org/doi/10.1175/JCLI-D-19-0405.1}, volume = {33}, year = {2020} } @article{tc-14-2909-2020, author = {Willibald, Fabian and Kotlarski, Sven and Gr{\^{e}}t-Regamey, Adrienne and Ludwig, Ralf}, doi = {10.5194/tc-14-2909-2020}, issn = {1994-0424}, journal = {The Cryosphere}, month = {sep}, number = {9}, pages = {2909--2924}, publisher = {Copernicus GmbH}, title = {{Anthropogenic climate change versus internal climate variability: impacts on snow cover in the Swiss Alps}}, url = {https://tc.copernicus.org/articles/14/2909/2020/}, volume = {14}, year = {2020} } @article{Wilson2018, abstract = {The prevalence and increased frequency of high-magnitude Glacial Lake Outburst Floods (GLOFs) in the Chilean and Argentinean Andes suggests this region will be prone to similar events in the future as glaciers continue to retreat and thin under a warming climate.

This study presents new glacial lake inventories for 1986, 2000 and 2016, covering the Central Andes, Northern Patagonia and Southern Patagonia. Our aim was to characterise the physical attributes, spatial distribution and temporal development of glacial lakes in these three sub-regions using Landsat satellite imagery and image datasets available in Google Earth and Bing Maps. Glacial lake water volume was also estimated using an empirical area-volume scaling approach. Results reveal that glacial lakes across the study area have increased in number (43{\%}) and areal extent (7{\%}) between 1986 and 2016. Such changes equate to a glacial lake water volume increase of 65 km3 during the 30-year observation period.

A growing body of work suggests that the extreme weather events that drive inland flooding are likely to increase in frequency and magnitude in a warming climate, thus potentially increasing flood damages in the future. We use hydrologic projections based on the Coupled Model Intercomparison Project Phase 5 (CMIP5) to estimate changes in the frequency of modeled 1 {\%} annual exceedance probability (1 {\%} AEP, or 100-year) flood events at 57 116 stream reaches across the contiguous United States (CONUS). We link these flood projections to a database of assets within mapped flood hazard zones to model changes in inland flooding damages throughout the CONUS over the remainder of the 21st century. Our model generates early 21st century flood damages that reasonably approximate the range of historical observations and trajectories of future damages that vary substantially depending on the greenhouse gas (GHG) emissions pathway. The difference in modeled flood damages between higher and lower emissions pathways approaches USD 4 billion per year by 2100 (in undiscounted 2014 dollars), suggesting that aggressive GHG emissions reductions could generate significant monetary benefits over the long term in terms of reduced flood damages. Although the downscaled hydrologic data we used have been applied to flood impacts studies elsewhere, this research expands on earlier work to quantify changes in flood risk by linking future flood exposure to assets and damages on a national scale. Our approach relies on a series of simplifications that could ultimately affect damage estimates (e.g., use of statistical downscaling, reliance on a nationwide hydrologic model, and linking damage estimates only to 1 {\%} AEP floods).

Here we use satellite observations and a numerical model to investigate changes in lake heatwaves for hundreds of lakes worldwide from 1901 to 2099. We show that lake heatwaves will become hotter and longer by the end of the twenty-first century. For the high-greenhouse-gas-emission scenario (Representative Concentration Pathway (RCP) 8.5), the average intensity of lake heatwaves, defined relative to the historical period (1970 to 1999), will increase from 3.7 ± 0.1 to 5.4 ± 0.8 degrees Celsius and their average duration will increase dramatically from 7.7 ± 0.4 to 95.5 ± 35.3 days. In the low-greenhouse-gas-emission RCP 2.6 scenario, heatwave intensity and duration will increase to 4.0 ± 0.2 degrees Celsius and 27.0 ± 7.6 days, respectively. Surface heatwaves are longer-lasting but less intense in deeper lakes (up to 60 metres deep) than in shallower lakes during both historic and future periods. As lakes warm during the twenty-first century7,8, their heatwaves will begin to extend across multiple seasons, with some lakes reaching a permanent heatwave state. Lake heatwaves are likely to exacerbate the adverse effects of long-term warming in lakes and exert widespread influence on their physical structure and chemical properties.

In contrast, anomalous cool Arctic summers and their impacts on the large-scale circulation have received little attention. In this study, we use atmospheric reanalysis data to reveal a dominant pattern of summer 1000–500-hPa thickness variability north of 30°N and its association with East Asian heat waves. It is found that the second thickness pattern exhibits strong interannual variability but does not exhibit any trend. Spatially, the positive phase of the second thickness pattern corresponds with significant Arctic cold anomalies in the mid- and low troposphere, which are surrounded by warm anomalies outside the Arctic. This pattern is the thermodynamic expression of the leading pattern of upper-tropospheric westerly variability and significantly correlated with the frequency of East Asian heat waves. The Arctic has experienced frequent summer cold anomalies since 2005, accompanied by strengthened tropospheric westerly winds over most of the Arctic and weakened westerlies over the mid- and low latitudes of Asia. The former significantly enhances baroclinicity over the Arctic, which dynamically contributes to increased frequency of anomalous low surface pressure during summer along with decreased frequency over high latitudes of Eurasia and North America. The latter is exhibited by sustained high pressure anomalies in the mid- and low troposphere that dynamically facilitate the occurrence of East Asian heat waves. A systematic northward shift of Asian zonal winds dynamically links Arctic cold anomalies with East Asian heat waves and produces a seesaw structure in zonal wind anomalies over the Arctic and the Tibetan Plateau (the third pole).

This paper aims to investigate spatiotemporal variations of drought in mainland China over 1961?2016 based on the standardized precipitation evapotranspiration index (SPEI) at the 1- and 12-month timescales. The trend significance and magnitude of 12-month SPEI were analysed using the modified Mann?Kendall (MMK) method and Sen's slope values. The empirical orthogonal function (EOF) and ensemble empirical mode decomposition (EEMD) were applied to analyse the spatial patterns and periods in 1-month SPEI series. The results showed that the temporal fluctuations of SPEI were weaker as the timescale increased. The droughts in 1960s were the severest than in other decades. The sites with SPEI {\textless} ?5 (denoting the extreme droughts) mainly located in the northwestern and southwestern China. An overall wetter trend was detected in most regions of China, except the belt from northeastern to middle and southwestern China. The 1-month SPEI had shorter than 1.20-year of mean periods for the seven sub-regions and China, while had 0.22?2.95?years of mean periods at different sites. Residuals (decomposed from 1-month SPEI) showed increasing trends in most of the sub-regions except sub-region 3. In northern and northwestern China, longer periods of SPEI were detected. The highest values of EOF1 and EOF2 illustrated the eastern and northeastern China were drought-sensitive areas. From the correlations between 1-month SPEI and the atmospheric circulations, the AO was the main physical factor that influenced drought occurrence in mainland China.

In addition, future changes of surface wind speed under the Shared Socioeconomic Pathway scenarios of 1-2.6, 2-4.5, and 5-8.5 (SSP1-2.6, SSP2-4.5, and SSP5-8.5) are also provided, by using 18 out of the 24 models with all three scenarios. Results show that multimodel ensemble mean of CMIP6 can well capture the spatial distributions of the annual, summer, and winter surface wind speed and generally performs better than both the median of the individual CMIP6 GCMs and multimodel ensemble mean of CMIP5 in monthly, seasonal, and annual wind climatology. However, CMIP6 GCMs fail to reproduce the observed decreasing trends, in terms of magnitude and/or sign. Meanwhile, the annual cycle of the surface wind speed simulated by CMIP6 GCMs falsely demonstrates the maximum in winter instead of spring. In the context of global warming, surface wind speed is projected to decrease in most parts of China in the middle and late 21st century under the three scenarios. Moreover, the trends of wind speed averaged over China will decrease significantly in both annual and winter under all three scenarios, but it will increase significantly in summer under SSP5-8.5.}, annote = {https://doi.org/10.1029/2020JD033611}, author = {Wu, Jie and Shi, Ying and Xu, Ying}, doi = {10.1029/2020JD033611}, issn = {2169-897X}, journal = {Journal of Geophysical Research: Atmospheres}, keywords = {CMIP6,China,evaluation,projection,surface wind speed}, month = {nov}, number = {22}, pages = {e2020JD033611}, publisher = {John Wiley {\&} Sons, Ltd}, title = {{Evaluation and Projection of Surface Wind Speed Over China Based on CMIP6 GCMs}}, url = {https://doi.org/10.1029/2020JD033611}, volume = {125}, year = {2020} } @article{Wu2016, abstract = {Climate change refers to long-term shifts in weather conditions and patterns of extreme weather events.

These impacts are related to different aspects of energy systems, including energy supply and demand, but also to cost and transport of energy. On the supply side, renewable energy sources including bio-energy, and hydro, solar and wind power are impacted by climate change in varying degrees due to changes and variability in precipitation , temperature, wind speed and solar irradiation 2,4-7. Thermal power plants (for example, fossil fuel, biomass and nuclear) face temperature-related impacts on cooling systems and, less substantial , on turbine efficiency 8. With changes in climate, impacts on thermal power plant may be exacerbated due to national and regional environmental regulations on cooling water withdrawal, consumption and release into natural water bodies, which may result in power generation curtailments 9,10. Climate change and climate extremes can also affect the resilience of energy systems and the reliability of energy supply, via impacts on transmission systems or infrastructure siting 3,11-13. Furthermore, climate change may impact energy supply potentials (for example, for bioenergy) although impacts on land use and competition with other sectors such as food production 14. On the demand side, climate change influences energy demand by affecting the duration and magnitude of diurnal and seasonal heating and cooling requirements 15. Finally, climate change may impact energy systems indirectly by affecting cross-sectoral competition for resources, such as water for producing hydropower, for cooling thermal power plants and/or for uses such as domestic supply, freshwater ecosystems, irrigation and manufacturing 16. This could indicate additional energy demand for alternative water sources, such as for desalinization. Understandably, energy systems can also adapt to climate change impacts. Adaptation mechanisms may include reducing energy demand, reducing water demands for cooling operations through alternative cooling technologies (that is, recirculating versus once-through), increasing energy generation capacity and energy storage 17. The vulnerability of the energy sector can also be reduced by changes in the mix of electricity generation technologies 3. Although our knowledge of climate change impacts on energy systems has increased substantially over the past few decades, there remains a lack of comprehensive overview of impacts across spatial scales. Here, we analyse results of 220 studies projecting climate impacts on energy systems globally and at the regional scale. Globally, a potential increase in cooling demand and decrease in heating demand can be anticipated, in contrast to slight decreases in hydropower and thermal energy capacity. Impacts at the regional scale are more mixed and relatively uncertain across regions, but strongest impacts are reported for South Asia and Latin America. Our assessment shows that climate impacts on energy systems at regional and global scales are uncertain due partly to the wide range of methods and non-harmonized datasets used. For a comprehensive assessment of climate impacts on energy, we propose a consistent multi-model assessment framework to support regional-to-global-scale energy planning.

Although both human activities and climate variability have significant effects on river flows over China, there are large regional north-south contrasts. Over northern China, human activities generally intensify hydrological droughts. We find that human activities exacerbated drought deficit by about 70?200{\%} from 2004 to 2015. In contrast, droughts over southern China are generally alleviated by human activities. For instance, irrigation and water management (such as reservoir operation and water abstraction) increase drought StDef (standardized drought deficit volume) by about 80{\%} in the Yellow River (north) but reduce it by about 20{\%} in the Yangtze River (south). Human activities slightly reduce drought deficit in the Yangtze River due to the combination of large reservoir storage and low ratio of agriculture consumption to abstracted irrigation water. In contrast, hydrological drought is aggravated in the semiarid Yellow River basin because of high water consumption from agricultural sectors. This study suggests that human activities have contrasting influences on hydrological drought characteristics in the northern (intensification) and southern (mitigation) parts of China.

The spatiotemporal variations in drought characteristics (e.g., the drought occurrence time, duration, severity, peak, and frequency and the percentage of stations suffering from drought (PSSD) were estimated by the projected SPEI for the periods 2011-2040, 2041-2070 and 2071-2100. The results showed that mainland China would experience more frequent and severe droughts in the future than in the baseline period, as denoted by SPEI and the generated drought variables. In particular, drier areas of northwestern China were likely to suffer from worse drought conditions than those in other areas, with PSSD values of 60{\%} and 81{\%} by 2100 under the RCP4.5 and RCP 8.5 scenarios, respectively. Although the annual precipitation was projected to increase in most regions, drought conditions would still worsen because of increased the minimum and maximum air temperatures. However, the GCMs contributed more uncertainties to the projection of the SPEI than the stations or the RCPs, because the GCMs made a larger contribution to the variance ({\textgreater}40{\%}). The SPEI performed better than the other indices that only accounted for the influence of a single variable. The relationship between crop yields and the three drought indices varied by month, crop (maize and cotton), and timescale (3- and 6-month).

Based on the boundary data of lakes, some moderate-high resolution remote sensing datasets including MODIS and Landsat TM/ETM+ images and the meteorological data, the spatial-temporal variations of lake ice phenology in the Hoh Xil region during the period 2000–2011 were analyzed by using RS and GIS technology. And the factors affecting the lake ice phenology were also identified. Some conclusions can be drawn as follows. (1) The time of freeze-up start (FUS) and freeze-up end (FUE) of lake ice appeared in the late October–early November, mid-November–early December, respectively. The duration of lake ice freeze-up was about half a month. The time of break-up start (BUS) and break-up end (BUE) of lake ice were relatively dispersed, and appeared in the early February–early June, early May–early June, respectively. The average ice duration (ID) and the complete ice duration (CID) of lakes were 196 days and 181 days, respectively. (2) The phenology of lake ice in the Hoh Xil region changed dramatically in the last 10 years. Specifically, the FUS and FUE time of lake ice showed an increasingly delaying trend. In contrast, the BUS and BUE time of lake ice presented an advance. This led to the reduction of the ID and CID of lake. The average rates of ID and CID were–2.21 d/a and–1.91 d/a, respectively. (3) The variations of phenology and evolution of lake ice were a result of local and climatic factors. The temperature, lake area, salinity and shape of the shoreline were the main factors affecting the phenology of lake ice.

The first mode of Eurasian snow cover extent (SCE) represents a seasonally asymmetric trend between spring and fall. The spring SCE shows a decreasing trend, while the fall SCE particularly in October exhibits a clear increasing trend. This seasonally asymmetric trend of SCE is closely linked to Arctic sea ice decline accompanied by warming in the northern Eurasia. The decreased SCE during spring is primarily attributed to the warm air temperature anomalies, while the increased SCE in October results from the loss of sea ice and the ensuing moisture transport to the atmosphere, which is realized as increased snow in October. The second mode of Eurasian SCE, on the other hand, is closely related to Arctic Oscillation (AO), which is a dominant mode of Northern Hemisphere atmospheric variability. The snow cover variability over Europe during winter is largely affected by AO variability, rather than the warming signal represented by the first CSEOF mode.

In this study, we analyse the observed changes in twelve extreme temperature indices and compare them with model simulations based on the Coupled Model Intercomparison Project Phase 5 (CMIP5). An optimal fingerprinting method is used to perform detection and attribution analyses on the changes in absolute intensity, percentile-based frequency, fixed threshold exceedances of temperature extremes and diurnal temperature ranges in the central and eastern TP. The results show that during 1958–2017 the TP has experienced increasing intensity and frequency of warm extremes and decreasing intensity and frequency of cold extremes, with almost all these changes larger than those in China and East China. The detection results and attribution analyses show that the anthropogenic (ANT) signal can be robustly detected in the trends for all extreme indices on the TP, and the natural (NAT) signal in some cases, too. The attributable contribution from ANT is estimated to be much larger than that from NAT for most indices. The study also indicates that the CMIP5 models may underestimate the magnitude of warming in some temperature extremes, especially the indices related to cold extremes.

The regressions explain 0.25–0.60 of the variance in observed annual area burned during 1980–2004, depending on the ecoregion. We also parameterize daily area burned with temperature, precipitation, and relative humidity. This approach explains ∼0.5 of the variance in observed area burned over forest ecoregions but shows no predictive capability in the semi-arid regions of Nevada and California. By applying the meteorological fields from 15 climate models to our fire prediction models, we quantify the robustness of our wildfire projections at midcentury. We calculate increases of 24–124{\%} in area burned using regressions and 63–169{\%} with the parameterization. Our projections are most robust in the southwestern desert, where all GCMs predict significant (p {\textless} 0.05) meteorological changes. For forested ecoregions, more GCMs predict significant increases in future area burned with the parameterization than with the regressions, because the latter approach is sensitive to hydrological variables that show large inter-model variability in the climate projections. The parameterization predicts that the fire season lengthens by 23 days in the warmer and drier climate at midcentury.

While computing gains have allowed for simulated TC intensity to increase in global climate models as a result of increased horizontal resolution, many configurations utilize prescribed, noninteractive SSTs as a surface boundary condition to minimize computational cost and produce more accurate TC climatologies. Here, an idealized slab ocean is coupled to a 0.25° variable-resolution version of the Community Atmosphere Model (CAM) to improve closure of the surface energy balance and reproduce observed Northern Hemisphere cold wakes. This technique produces cold wakes that are realistic in structure and evolution and with magnitudes similar to published observations, without impacting large-scale SST climatology. Multimember ensembles show that the overall number of TCs generated by the model is reduced by 5{\%}–9{\%} when allowing for two-way air–sea interactions.

Trend principal component (TPC), regression, wavelet and composite analyses are used to investigate the trend, frequency and inter/intra-annual variability of extreme events (dryness/wetness of rainfall) over Ethiopia. All methods of analysis, applied to monthly mean data, show that the north and northwest regions of Ethiopia experienced frequent and more severe drought conditions centred at the year 1983/1984, a recovery in the middle of the study period and a return to moderate dry events in recent years. For the southern and southwestern regions, drought conditions have become more frequent and intense during the study period, particularly since ?1997. Analysis at the seasonal scale shows that the observed drying trend over the south and southwestern regions of the country is dominated by the spring season, which corresponds to the season of maximum precipitation. No observed long-term trend is found in the north, northwestern and central mountainous regions of the country. This contrast reflects differing climate sensitivities of these different portions of the country: the observed periodicity of dryness/wetness over the northern regions corresponds largely to ENSO variability in both the spring and summer rainy seasons, while the drying trend in the south and southwest is associated with Atlantic Ocean warming and sea surface temperature gradients across the western Pacific Ocean.}, author = {Zeleke, T T and Giorgi, F and Diro, G T and Zaitchik, B F}, doi = {10.1002/joc.5122}, issn = {0899-8418}, journal = {International Journal of Climatology}, keywords = {Ethiopia,PDSI,SPI,TPC,drought,variability,wavelet}, month = {nov}, number = {13}, pages = {4733--4748}, publisher = {John Wiley {\&} Sons, Ltd}, title = {{Trend and periodicity of drought over Ethiopia}}, url = {http://doi.wiley.com/10.1002/joc.5122}, volume = {37}, year = {2017} } @article{Zeng2019, author = {Zeng, Zhenzhong and Ziegler, Alan D and Searchinger, Timothy and Yang, Long and Chen, Anping and Ju, Kunlu and Piao, Shilong and Li, Laurent Z X and Ciais, Philippe and Chen, Deliang and Liu, Junguo and Azorin-Molina, Cesar and Chappell, Adrian and Medvigy, David and Wood, Eric F.}, doi = {10.1038/s41558-019-0622-6}, issn = {1758-678X}, journal = {Nature Climate Change}, month = {dec}, number = {12}, pages = {979--985}, publisher = {Nature Publishing Group}, title = {{A reversal in global terrestrial stilling and its implications for wind energy production}}, url = {http://www.nature.com/articles/s41558-019-0622-6}, volume = {9}, year = {2019} } @article{Zha2017, author = {Zha, Jinlin and Wu, Jian and Zhao, Deming and Yang, Qidong}, doi = {10.1016/j.jweia.2017.07.019}, issn = {0167-6105}, journal = {Journal of Wind Engineering {\&} Industrial Aerodynamics}, keywords = {near-surface wind speed}, pages = {156--167}, publisher = {Elsevier Ltd}, title = {{Changes of the probabilities in different ranges of near-surface wind speed in China during the period for 1970–2011}}, url = {http://dx.doi.org/10.1016/j.jweia.2017.07.019}, volume = {169}, year = {2017} } @article{Zha2019, abstract = {A lasting decrease in the near-surface wind speed (SWS) in China has been revealed, but a following short-term strengthening in the SWS was rarely noted.

The major results are summarized as follows: the SWS showed a significant decrease in the last 30 years, but a short-term strengthening in SWS was observed during the winter since 2000 in Eastern China. The SWS in Eastern China showed a significant decrease of − 0.11 m s−1 decade−1 from 1981 to 1999, followed by a weak increase of 0.0008 m s−1 decade−1 from 2000 to 2011. The short-term strengthening in the SWS since 2000 was mainly induced by the changes of the pressure-gradient force (PGF), which could be attributed to the changes of the sea-level pressure (SLP) in the region (51°–69.75° N, 51.75°–111.75° E). Furthermore, the changes of the PGF during the two periods of 1981–1999 and 2000–2011 were consistent with those of the SLP in the region (51°–69.75° N, 51.75°–111.75° E). The correlation coefficient between PGF and SLP was 0.32 and 0.66 during the period 1981–1999 and 2000–2011, respectively.

The relationships between the intensity and the area of droughts for a specific duration were analyzed by the intensity–area–duration method. The results show that areas with a significant trend in dryness can be found in a band reaching from the southwest to the northeast of China, while areas with significant trends in wetness are especially detected in the northern river basins in recent decades. In addition, for recent years (2000–2013), most of the ten major hydrological regions show opposite trends in the SPI when compared to the whole study period (1960–2013) except for the central and southwestern parts of China. This dryness/wetness trends are related to the intensity and duration of drought events, which have been stronger and lasted longer in the detected dryness band except for some northern river basins. A regional shift of drought centers is found from the northwest to the southeast within Central China. Moreover, a decreasing trend in drought area is observed, which might be related to the regional changes in precipitation pattern associated with the atmosphere–ocean interaction. Changes in the SST of the Tropical Pacific and the Tropical Indian Ocean may have resulted in frequent severe drought events of small areal extent in the central and southwestern parts of China.

The results show that near-surface wind speeds decreased by approximately − 0.109 ms−1 decade−1 from 1958 to 2015 in China; however, this decreasing trend has not been evident since 2000. The decreasing trend was caused by the weakening of both the zonal (u) and meridional (v) components of wind vectors during all seasons. Weakened v components are closely related to the weakened Siberian High (SH), and the decreasing pressure gradient associated with the SH causes a reduction in the north wind. The reduction in the u component has a limited association with the SH from a nationwide perspective, and the enhanced geopotential height over Northeast Asia plays a non-negligible role in the variability of u and causes a weakening of the prevailing west wind in Northeast China.

Existing studies hardly separated the two components and analyzed it as a whole based on time series vegetation index data, which cannot provide a clear and comprehensive picture for grassland degradation and desertification. Here we propose an integrated assessment strategy, by considering both state conversion and within-state change of grasslands, to investigate grassland degradation and desertification process in Central Asia. First, annual maps of grasslands and sparsely vegetated land were generated to track the state conversions between them. The results showed increasing grasslands were converted to sparsely vegetated lands from 2000 to 2014, with the desertification region concentrating in the latitude range of 43–48° N. A frequency analysis of grassland vs. sparsely vegetated land classification in the last 15 yr allowed a recognition of persistent desert zone (PDZ), persistent grassland zone (PGZ), and transitional zone (TZ). The TZ was identified in southern Kazakhstan as one hotspot that was unstable and vulnerable to desertification. Furthermore, the trend analysis of Enhanced Vegetation Index during thermal growing season (EVITGS) was investigated in individual zones using linear regression and Mann-Kendall approaches. An overall degradation across the area was found; moreover, the second desertification hotspot was identified in northern Kazakhstan with significant decreasing in EVITGS, which was located in PGZ. Finally, attribution analyses of grassland degradation and desertification were conducted by considering precipitation, temperature, and three different drought indices. We found persistent droughts were the main factor for grassland degradation and desertification in Central Asia.

Most of the existing studies on the attribution of global stilling do not take changing surface friction into account. In addition, there are other changes in the climate system, such as aerosol loading, which could have an impact on atmospheric circulation, but are not included in the majority of current models either.

In our methods, we neglected the vertical influencing factors on surface wind speed but took the aerosols' changes on atmospheric circulation and gradual urbanization effect on surface wind speed into account.

Two-level and three-level hybrid clustering analysis as well as common indices used to trigger HHWS, including spatial synoptic classification (SSC), and the 90th, 95th, and 99th percentiles of minimum and relative minimum temperature (using a 10day reference period), were calculated using a summertime weather dataset in Detroit from 1976 to 2006. The days classified as ‘hot' with hybrid clustering analysis, SSC, minimum and relative minimum temperature methods differed by method type. SSC tended to include the days with, on average, 2.5°C lower daily minimum temperature and 5.3°C lower dew point than days identified by other methods. These metrics were evaluated by comparing their performance in predicting excess daily mortality. The 99th percentile of minimum temperature was generally the most predictive, followed by the three-level hybrid clustering method, the 95th percentile of minimum temperature, SSC and others. Our proposed clustering framework has more flexibility and requires less substantial meteorological prior information than the synoptic classification methods. Comparison of these metrics in predicting excess daily mortality suggests that metrics thought to better characterize physiological heat stress by considering several weather conditions simultaneously may not be the same metrics that are better at predicting heat-related mortality, which has significant implications in HHWSs.}, author = {Zhang, Kai and Rood, Richard B. and Michailidis, George and Oswald, Evan M. and Schwartz, Joel D. and Zanobetti, Antonella and Ebi, Kristie L. and O'Neill, Marie S.}, doi = {10.1016/j.envint.2012.05.001}, issn = {01604120}, journal = {Environment International}, month = {oct}, pages = {23--29}, publisher = {Pergamon}, title = {{Comparing exposure metrics for classifying ‘dangerous heat' in heat wave and health warning systems}}, url = {https://www.sciencedirect.com/science/article/pii/S0160412012000992?via{\%}3Dihub https://linkinghub.elsevier.com/retrieve/pii/S0160412012000992}, volume = {46}, year = {2012} } @article{Zhao2017a, author = {Zhao, Tianbao and Dai, Aiguo}, doi = {10.1007/s10584-016-1742-x}, issn = {0165-0009}, journal = {Climatic Change}, month = {oct}, number = {3}, pages = {535--548}, title = {{Uncertainties in historical changes and future projections of drought.

Climate models consistently project that HW frequency, severity, and duration will increase markedly over this century. For urban residents, the urban heat island (UHI) effect further exacerbates the heat stress resulting from HWs. Here we use a climate model to investigate the interactions between the UHI and HWs in 50 cities in the United States under current climate and future warming scenarios. We examine UHI2m (defined as urban-rural difference in 2m-height air temperature) and UHIs (defined as urban-rural difference in radiative surface temperature). Our results show significant sensitivity of the interaction between UHI and HWs to local background climate and warming scenarios. Sensitivity also differs between daytime and nighttime. During daytime, cities in the temperate climate region show significant synergistic effects between UHI and HWs in current climate, with an average of 0.4 K higher UHI2m or 2.8 K higher UHIs during HWs than during normal days. These synergistic effects, however, diminish in future warmer climates. In contrast, the daytime synergistic effects for cities in dry regions are insignificant in the current climate, but emerge in future climates. At night, the synergistic effects are similar across climate regions in the current climate, and are stronger in future climate scenarios. We use a biophysical factorization method to disentangle the mechanisms behind the interactions between UHI and HWs that explain the spatial-temporal patterns of the interactions. Results show that the difference in the increase of urban versus rural evaporation and enhanced anthropogenic heat emissions (air conditioning energy use) during HWs are key contributors to the synergistic effects during daytime. The contrast in water availability between urban and rural land plays an important role in determining the contribution of evaporation.

Three heat stress indicators, based on both temperature and humidity conditions, are used to investigate present-day model biases and spreads in future climate projections. Present day estimates of heat stress indicators from observational data shows that humid tropical areas tend to experience more frequent heat stress than other regions do, with a total frequency of heat stress 250-300 d yr-1. The most severe heat stress is found in the Sahel and south India. Present-day GCM simulations tend to underestimate heat stress over the tropics due to dry and cold model biases. The model based estimates are in better agreement with observation in mid to high latitudes, but this is due to compensating errors in humidity and temperature. The severity of heat stress is projected to increase by the end of the century under climate change scenario RCP8.5, reaching unprecedented levels in some regions compared with observations. An analysis of the different factors contributing to the total spread of projected heat stress shows that spread is primarily driven by the choice of GCMs rather than the choice of indicators, even when the simulated indicators are bias-corrected.

It uses two large ensemble climate models (50-member CanESM2 and 40-member CESM1) under the RCP 8.5 scenario to robustly assess frequency changes up to the 100-year drought, relative to the 1980–2009 reference period. Meteorological droughts, linked solely to precipitation deficit, are represented by the 1-month Standardized Precipitation Index (SPI), whereas hydrological droughts are characterized by the 1-month Streamflow Drought Index (SDI), based on hydrological simulation using a lumped hydrological model. Results show widely different patterns for future changes in extreme meteorological versus hydrological droughts. Future meteorological droughts show patterns of increasing and decreasing frequency that roughly match future expected changes of mean summer precipitation, although some regions are nonetheless projected to see more frequent extreme meteorological droughts despite increases in mean summer precipitation. The frequency changes for the 100-year meteorological droughts can be quite severe, with up to a 20-fold increase observed over some watersheds. On the other hand, hydrological droughts, which combine the effect of precipitation and temperature changes, show a mostly uniform pattern of large to very large increases in drought frequency. This shows that the projected temperature increase is a main driver of future extreme hydrological droughts, enough to overcome the projected increase in mean summer precipitation for many North American catchments. Projected changes in both meteorological and hydrological droughts get consistently worse for the longer considered return periods. In other words, frequency changes for the 100-year droughts are more significant than those expected for the 2- and 20-year droughts. This gradual worsening toward larger extremes has potentially large societal and economic impacts.

CO2 fertilization effects explain most of the greening trends in the tropics, whereas climate change resulted in greening of the high latitudes and the Tibetan Plateau. LCC contributed most to the regional greening observed in southeast China and the eastern United States.

However, they have not considered multiple indices with combined effects on deriving HPET, which can result in large uncertainties in assessing climate change impacts on HPET and related extremes. Therefore, we develop a new framework with high-resolution projections and an ensemble of 10 indices to quantify the impacts of climate change on HPET and related perceived extremes as well as to address uncertainties in both empirical indices and emission scenarios over China. Our findings reveal that different combinations of climatic variables can lead to two opposite conclusions for both normal and extreme conditions. For example, by using indices only considering the combined effect of temperature and relative humidity, China is projected to have an elevated increase in the HPET and in the frequency of high-temperature extremes. By taking into account wind speed, the country expects to have the HPET even lower than the surface air temperature and an increase in the frequency of low-temperature extremes. In addition, the resulting range of HPET due to uncertainty in indices is greater than the uncertainty range derived from different emission scenarios for the entire country.

We also examined the rate of new leaf development following leaf removal to simulate responses to herbivory as functions of both CO 2 and plant size. The experimental CO 2 values (300, 400, 500. and 600 µmol mol −1 ) corresponded approximately to the concentration that existed during the middle of the 20th century, the current concentration and near and long-term projections for this century (2050 and 2090), respectively. Over 250 d, increasing CO 2 resulted in significant increases in leaf area, leaf and stem weight, and rhizome length relative to the 300 µmol mol −1 baseline with the greatest relative increase occurring from 300 to 400 µmol mol −1 . There was a nonsignificant (P = 0.18) increase in urushiol concentration in response to CO 2 ; however, because of the stimulatory effect of CO 2 on leaf biomass, the amount of urushiol produced per plant increased significantly for all CO 2 above the 300 µmol mol −1 baseline. Significant increases in the rate of leaf development following leaf removal were also observed with increasing CO 2 . Overall, these data confirm earlier, field-based reports on the CO 2 sensitivity of poison ivy but emphasize its ability to respond to even small (∼ 100 µmol mol −1 ) changes in CO 2 above the mid-20th century carbon dioxide baseline and suggest that its rate of spread, its ability to recover from herbivory, and its production of urushiol, may be enhanced in a future, higher CO 2 environment.}, author = {Ziska, L.

We aimed to analyse trends in pollen seasonality and pollen load and to establish whether there are specific climate-related links to any observed changes. Methods: For this retrospective data analysis, we did an extensive search for global datasets with 20 years or more of airborne pollen data that consistently recorded pollen season indices (eg, duration and intensity). 17 locations across three continents with long-term (approximately 26 years on average) quantitative records of seasonal concentrations of multiple pollen (aeroallergen) taxa met the selection criteria. These datasets were analysed in the context of recent annual changes in maximum temperature (T max ) and minimum temperature (T min ) associated with anthropogenic climate change. Seasonal regressions (slopes) of variation in pollen load and pollen season duration over time were compared to T max , cumulative degree day T max , T min , cumulative degree day T min , and frost-free days among all 17 locations to ascertain significant correlations. Findings: 12 (71{\%}) of the 17 locations showed significant increases in seasonal cumulative pollen or annual pollen load. Similarly, 11 (65{\%}) of the 17 locations showed a significant increase in pollen season duration over time, increasing, on average, 0{\textperiodcentered}9 days per year. Across the northern hemisphere locations analysed, annual cumulative increases in T max over time were significantly associated with percentage increases in seasonal pollen load (r=0{\textperiodcentered}52, p=0{\textperiodcentered}034) as were annual cumulative increases in T min (r=0{\textperiodcentered}61, p=0{\textperiodcentered}010). Similar results were observed for pollen season duration, but only for cumulative degree days (higher than the freezing point [0°C or 32°F]) for T max (r=0{\textperiodcentered}53, p=0{\textperiodcentered}030) and T min (r=0{\textperiodcentered}48, p=0{\textperiodcentered}05). Additionally, temporal increases in frost-free days per year were significantly correlated with increases in both pollen load (r=0{\textperiodcentered}62, p=0{\textperiodcentered}008) and pollen season duration (r=0{\textperiodcentered}68, p=0{\textperiodcentered}003) when averaged for all 17 locations. Interpretation: Our findings reveal that the ongoing increase in temperature extremes (T min and T max ) might already be contributing to extended seasonal duration and increased pollen load for multiple aeroallergenic pollen taxa in diverse locations across the northern hemisphere. This study, done across multiple continents, highlights an important link between ongoing global warming and public health—one that could be exacerbated as temperatures continue to increase.

These findings agree with previously projected increases in high extremes under the Special Report on Emissions Scenarios climate projections, and are important to highlight due to the potential consequences on reproductive processes of in-stream species, swamp forest ecology, and socio-economy in the floodplain, amidst a growing literature that more strongly emphasises future droughts and their impact on the viability of the rainforest system over greater Amazonia.}, author = {Zulkafli, Zed and Buytaert, Wouter and Manz, Bastian and Rosas, Claudia V{\'{e}}liz and Willems, Patrick and Lavado-Casimiro, Waldo and Guyot, Jean-Loup and Santini, William}, doi = {10.1088/1748-9326/11/1/014013}, issn = {1748-9326}, journal = {Environmental Research Letters}, number = {1}, pages = {14013}, publisher = {IOP Publishing}, title = {{Projected increases in the annual flood pulse of the Western Amazon}}, url = {http://dx.doi.org/10.1088/1748-9326/11/1/014013}, volume = {11}, year = {2016} }
