GENEVA, June 19 — The Intergovernmental Panel on Climate Change (IPCC) and the American Geophysical Union (AGU) announce access to the full library of AGU Publications for IPCC authors working on the Panel’s Seventh Assessment Report, or AR7.
“This landmark decision is an invaluable scientific boost for the IPCC’s ongoing work,” said IPCC Chair Jim Skea. “It will enable our authors from developing countries and those facing access barriers to enhance their scientific contributions to the upcoming reports of IPCC’s three Working Groups assessing the latest science related to climate change. We encourage other major scientific publishers to consider following suit at this critical time for climate science.”
As a non-profit scholarly publisher, AGU publishes 24 peer-reviewed high-impact journals and four active book series, including monographs, advanced-level textbooks, and technical manuals across the entire spectrum of Earth and space sciences. It also runs the Earth and Space Science Open Archive.
AGU journals publish research articles, letters, commentaries and other types of scholarly content within the fields of Earth and space sciences. Covering topics ranging from atmospheric science and oceanography to geophysics, planetary science, and climate change, AGU journals are an essential mode of information sharing and enterprise building for the global scientific community.
“IPCC Reports provide authoritative scientific consensus on climate change to a broad spectrum of key players, from government and community leaders to industries and advocacy organizations,” said AGU President Brandon Jones. “Opening AGU publications’ portfolio to the authors of the Seventh Assessment Report provides greater equitable access to critical research of the scientific community, which can be assessed, considered, and weighed when informing the final report.”
Following the Panel’s agreement in February on the outlines of the three Working Group contributions during its 62nd Session held in Hangzhou, China, the IPCC has now completed the call for nominations of experts to act as Coordinating Lead Authors, Lead Authors, or Review Editors for the three key Working Group contributions to IPCC’s Seventh Assessment Report.
Hundreds of experts in different scientific domains worldwide will be selected to volunteer their time and expertise to produce the new set of IPCC Reports. Author teams will reflect a range of scientific, technical, and socio-economic knowledge. Coordinating Lead Authors and Lead Authors will be responsible for drafting the different chapters of the Working Group contributions to the AR7 and, with the help of the Review Editors, revising those based on comments submitted during the two rounds of reviews by experts and governments.
IPCC author teams include experts from different regions to ensure geographic balance. The IPCC also seeks a balance in gender, as well as a balance between those authors with experience in working on IPCC Reports and those new to the process, including younger scientists.
The outlines of the three Working Group contributions to the AR7 were developed after a comprehensive scientific scoping meeting in December 2024 in Kuala Lumpur, Malaysia, before the Panel considered them and agreed upon them at the end of February.

Notes for Editors
What is the IPCC?
The Intergovernmental Panel on Climate Change (IPCC) is the UN body for assessing the science related to climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide political leaders with periodic scientific assessments concerning climate change, its implications and risks, as well as to put forward adaptation and mitigation strategies. In the same year the UN General Assembly endorsed the action by the WMO and UNEP in jointly establishing the IPCC. It has 195 member states.
Thousands of people from all over the world contribute to the work of the IPCC. For the assessment reports, scientists and experts volunteer their time as IPCC authors to assess the thousands of scientific papers published each year to provide a comprehensive summary of what is known about the drivers of climate change, its impacts and future risks, and how adaptation and mitigation can reduce those risks.
The IPCC has three working groups: Working Group I, dealing with the physical science basis of climate change; Working Group II, dealing with impacts, adaptation and vulnerability; and Working Group III, dealing with the mitigation of climate change. It also has a Task Force on National Greenhouse Gas Inventories that develops methodologies for measuring emissions and removals.
IPCC assessments provide governments, at all levels, with scientific information that they can use to develop climate policies. IPCC assessments are a key input into the international negotiations to tackle climate change. IPCC reports are drafted and reviewed in several stages, thus guaranteeing objectivity and transparency.
What is AGU
The American Geophysical Union (www.agu.org) is a global community supporting more than half a million scientists, advocates, and professionals in Earth and space sciences. Through broad and inclusive partnerships, AGU aims to advance discovery and solution science that accelerate knowledge and create solutions that are ethical, unbiased and respectful of communities and their values. Our programs include serving as a scholarly publisher, convening virtual and in-person events and providing career support. We live our values in everything we do, such as our net zero energy renovated building in Washington, D.C. and our Ethics and Equity Center, which fosters a diverse and inclusive geoscience community to ensure responsible conduct.
About the Seventh Assessment Cycle
Comprehensive scientific assessment reports are published every 5 to 7 years. The IPCC is currently in its seventh assessment cycle, which formally began in July 2023 with the elections of the new IPCC and Task Force Bureaus at the IPCC’s Plenary Session in Nairobi.
At its first Plenary Session in the seventh assessment cycle – the 60th Plenary Session in Istanbul, Türkiye, in January 2024 – the Panel agreed to produce in this cycle the three Working Group contributions to the Seventh Assessment Report (AR7), namely the Working Group I report on the Physical Science Basis, the Working Group II report on Impacts, Adaptation and Vulnerability and the Working Group III report on Mitigation of Climate Change. The Synthesis Report of the Seventh Assessment Report will be produced after the completion of the Working Group reports and released by late 2029.
During its 62nd Plenary Session held in Hangzhou, China, in February 2025, the Panel has agreed on the outlines of the three Working Group contributions to the Seventh Assessment Report (AR7).
The Panel decided already during the previous cycle to produce a Special Report on Climate Change and Cities and a Methodology Report on Short-lived Climate Forcers during AR7.. Scientists have also been asked to deliver a Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage.
At the IPCC’s 61st Plenary Session held in Sofia, Bulgaria, from 27 July to 2 August 2024, the Panel agreed upon the outlines for the Special Report on Climate Change and Cities scheduled for approval and publication in March 2027 and for the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers scheduled for publication in the second half 2027.
In addition, a revision of the 1994 IPCC Technical Guidelines on impacts and adaptation as well as adaptation indicators, metrics and guidelines, will be developed in conjunction with the Working Group II report and published as a separate product.
IPCC’s latest report, the Sixth Assessment Report, was completed in March 2023 with the release of its Synthesis Report, which provided direct scientific input to the First Global Stocktake process under the United Nations Framework Convention on Climate Change at COP28 in Dubai.
The Sixth Assessment Report comprises three Working Group contributions and a Synthesis Report. The Working Group I contribution Climate Change 2021: the Physical Science Basis was released on 9 August 2021. The Working Group II contribution, Climate Change 2022: Impacts, Adaptation and Vulnerability, was released on 28 February 2022. The Working Group III contribution, Climate Change 2022: Mitigation of Climate Change, was released on 4 April 2022 and the Synthesis Report on 20 March 2023. The Synthesis Report to the Sixth Assessment Report, distils and integrates the findings of the three Working Group assessments as well as the three Special Reports released in 2018 and 2019.
The special reports were on Global Warming of 1.5°C (October 2018.), Climate Change and Land (August 2019) and, the Ocean and Cryosphere in a Changing Climate (September 2019).

SBSTA 62,Bonn, Germany, 17 June 2025
Thank you SBSTA Chair (SBSTA Chair, Adonia Ayebare)
Your Excellencies, distinguished delegates, colleagues and friends, ladies and gentlemen,
First of all, thank you for the invitation to deliver the keynote address at this 17th Meeting of the Research Dialogue.
As the Chair of the Intergovernmental Panel on Climate Change – the IPCC – I will also take this opportunity to bring you up to date on the Panel’s work since the seventh assessment cycle began almost two years ago.
It is somewhat ironical that recent IPCC reports have communicated the need for urgency in responding to the manifest risks posed by climate change. Because, as we move from one assessment cycle to another, there is an inevitable hiatus while we prepare our new reports. Where is our sense of urgency? It’s a fair question to ask. We indeed may appear to be the El Niňo of the scientific assessment world – appearing every two-to-seven years.
But unlike El Niňo, we know when our reports will start to appear. We also know their scope, and the key scientific issues and knowledge gaps that they will address. So, let me first of all set out where we are in terms of plans for the seventh cycle, then reflect more on scientific issues linked to attribution, different warming levels and aspects of temperature overshoot, the measurement of impacts and adaptation, and the treatment of sustainable development and equity issues. For a wider take on the Seventh Assessment Report – or AR7 – let me advertise tomorrow’s IPCC side event where representatives of the Working Groups and the Task Force on National Greenhouse Gas Inventories – the TFI – will be setting out their plans.
So, in terms of work under way [SLIDE 2] a Special Report on Climate Change and Cities and a Methodology Repot on Short Lived Climate Forcers have been scoped, the authors have been selected and the first Lead Authors meetings have been held. We plan our first and only special report of the cycle to be approved and released in less than two years, in early 2027 and the Methodology Report in late 2027.
The member governments have agreed upon the outlines of the three Working Group contributions to the AR7 at the Panel’s last plenary in Hangzhou China. We have yet to settle the precise timeline for their production, but they could start appearing in mid-2028, while the Synthesis Report that will conclude the entire cycle must be approved by late 2029.
Alongside the Working Group II report, revised and updated technical guidelines on the assessment of impacts and adaptation will be produced as a distinct product, with a special emphasis on metrics and indicators. And here’s another quick IPCC advert, this matter will be discussed in depth at the mandated event on Friday morning.
And finally, the Panel has yet to agree on the scope of two reports: a Methodology Report on Carbon Dioxide Removal and Carbon Capture and Storage, and the Synthesis Report. We have almost completed work on the Methodology Report in Hangzhou, but have some residual issues to resolve on carbon dioxide and water bodies. The Synthesis Report will be scoped later in the cycle.
Now, turning to the specific scientific topics I mentioned.
For each, I will first set out the state of knowledge from the Sixth Assessment Report, or AR6, then I will show how these issues and knowledge gaps will be treated in the forthcoming reports.
On attribution [SLIDE 3], the very first sentence of the Summary for Policymakers of the AR6 Synthesis Report is a relevant high-level statement: “Human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming”. It couldn’t be clearer. We have high levels of confidence that some type of impacts can be attributed to human activities.
For example, we are highly confident [SLIDE 4] that human activities have caused observable increases in hot extremes. We have concluded that it is likely that human activities [SLIDE 5] are the main driver of the intensification of heavy precipitation. But we have lower confidence regarding human influence on agricultural and ecological drought [SLIDE 6]. And some of that lower confidence is due to lower levels of agreement in the assessed literature. The Seventh Assessment Report will address these lower confidence topics with a view, if it is supported by the evidence, to reaching robust conclusions.
But more work needs to be done to establish whether specific weather or climate events can be attributed to human activities. That’s why the forthcoming Working Group I report [SLIDE 7] will extend the attribution of large-scale changes in the climate system at the global and regional levels to the attribution of local changes and extremes such as tropical cyclones. Working Group I will explore cloud-resolving climate simulations down to the kilometre scale, the greater use of climate emulators and the use of artificial intelligence. Working Group II will extend the assessment of attribution to observed and projected impacts.
Turning to current and projected levels of warming [SLIDE 8], the World Meteorological Organisation, one of our parent organisations, has established that the annually averaged global mean near-surface temperature for the single year of 2024 was 1.55 °C above pre-industrial levels. This does not imply that the 1.5 °C warming level mentioned in the Paris long-term temperature goal has been breached. That is based on the mid-point of a 20-year long-run average. Estimates of current long-run warming averaged over multiple years vary between 1.34 and 1.41 ºC. But there is a 70% chance that average warming over the years 2025-2029 will exceed 1.5 ºC.
Looking forward, a communication challenge remains. There are plausible temperature pathways that can both “exceed” and “limit” warming to 1.5 °C [SLIDE 9]. This slide, based on work by Carbon Brief, shows that a pathway can exceed a given warming level in the short-medium term but still limit warming to that same level by the end of the century.
But to be clear, GHG emissions are still rising, and we are not on track to limit warming to 1.5 °C. This slide [SLIDE 10], from our other parent organisation, UNEP, is based on methods used in the IPCC Sixth Assessment Report combined with updated information. It shows that, even if all the current National Determined Contributions and net zero pledges were to be met in full, warming would at best be just below 2 °C by the end of the century.
The consequences and means of managing so-called overshoot – which means exceeding a specified global warming level, before returning to or below that level through net removals of CO2 from the atmosphere – will be covered in the Seventh Assessment Report. Here, there are significant knowledge gaps. What irreversible impacts, such as species loss, may we suffer if we surpass a given threshold? How will the Earth system, including the biosphere, respond to lower CO2 concentrations and a cooling climate? How well do adaptation options planned today function under conditions at higher levels of global warming?
What techniques and approaches can plausibly result in removals of CO2 from the atmosphere at scale? [SLIDE 11] What might be the wider social, economic and ecological consequences of deploying these options? In the sixth cycle, Working Group III, developed a taxonomy of carbon dioxide removal options, but more exploration is needed.
The scientific challenges cut across all of the IPCC Working Groups. In the seventh cycle, the Working Group I report will be assessing Earth system responses to overshoot [SLIDE 12]. Working Group III will assess a wide range of carbon dioxide removal methods [SLIDE 13]. Working Group II will assess the implications for human and natural systems of deploying these options. And the TFI will be developing methods for estimating emissions and removals associated with Carbon Dioxide Removal.
The seventh cycle will have an enhanced emphasis on impacts and adaptation [SLIDE 14]– though we will certainly not neglect mitigation. Compared to mitigation, adaptation to climate change has lacked the means to measure progress. Adaptation actions are more difficult to separate from wider infrastructure investment and patterns of development. We will shortly start work on revising and updating Technical Guidelines on assessing impacts and adaptation to help to fill that gap, and support the Global Goal on Adaptation. The guidelines will encompass goal setting, risk assessment, planning, implementation, and learning, monitoring and evaluation. And the Working Group II report will, for the first time include a chapter on finance, an indispensable precondition for successful adaptation.
And, overall, we will be paying much more attention to the role that climate action plays in advancing and promoting sustainable development, including and beyond the Sustainable Development Goals, or SDGs. In the sixth cycle [SLIDE 15], we showed that those who are most vulnerable to climate change have generally contributed the least of GHG emissions. We also showed [SLIDE 16] that across a range of human and natural systems, options for climate action, both adaptation and mitigation, have more synergies than trade-offs with the SDGs.
In the seventh assessment cycle, there will be a substantial treatment of equity, just transition and the distributional consequences of climate action across the Working Group contributions. Working Group II has a bullet point that is common to all regional and thematic chapters concerning the distributional nature of effects, covering human rights, equity and justice, and impacts on various vulnerable groups. There will also be a chapter devoted to responses to losses and damages disproportionately experienced by vulnerable communities and groups. It will also include ways of categorising and measuring losses and damages.
Working Group III [SLIDE 17] has an entire chapter devoted to sustainable development and mitigation. This comprehensive chapter will include distributional consequences for mitigation actions, synergies and trade-offs with sustainable development objectives, and implications for biodiversity and ecosystems, conservation, and restoration. In addition, the chapter addressing “futures”, which will contain the assessment of published scenarios at different temporal and geographical scales, will focus on both sustainable development and mitigation.
Ladies and gentlemen,
The relevant scientific communities are already working on these topics, and more. So, what does IPCC add? [SLIDE 18] Let me emphasise our unique capacity to assess and synthesise the vast and exponentially growing body of knowledge on climate change, its impacts, and available responses. Every individual scientific paper matters, but it’s only when individual papers are placed in the context of the overall body of evolving knowledge that the entire picture becomes clear. We know how to establish the level of confidence in key findings, draw out different perspectives and strands of thinking, and identify knowledge gaps. The findings in our existing reports are durable, and can be updated by others using methods from approved IPCC reports in light of new and emerging data. And, let me underline that the IPCC findings that are most durable actually concern climate action. I recall our message that every fraction of a degree of warming matters. The many adaptation and mitigation response options we have identified, explored and laid out for policymakers can be implemented now, and in the future, at any level of warming.
And, finally, and very importantly, we forge consensus between representatives of the scientific world and policymakers, the prerequisite for informed and effective policy-making.
It’s a unique and highly successful model – our rigorous assessment methods have paid off in terms of scientific credibility and user acceptance. Indeed, IPCC methods have been used as a model by other bodies, including IPBES. The IPCC – as well as our colleagues in the policy world – faces unprecedented and complex challenges in a turbulent world. But we are confident that our tried and tested ways of working will allow us to rise to these challenges and deliver clear, authoritative, timely and actionable findings for policymakers and other decision-makers over the next few years.
Thank you.
The Intergovernmental Panel on Climate Change is calling for nominations of participants to two three-day co-located workshops to be held in the first quarter of 2026:
This follows the Panel’s agreement of a proposal made by the IPCC Chair with the support of a drafting group, during its 62nd Session held in Hangzhou, China ( IPCC-LXII/Doc. 7, Rev.1 ).
The scope of the Workshop on Engaging Diverse Knowledge Systems is to consider what systems of knowledge the IPCC can engage with and assess within the framework of existing principles and procedures.
The scope of the Workshop on Methods of Assessment is to consider the means by which such knowledge systems can be assessed.
Both workshops will also consider the extent to which such means of synthesis and assessment may be conducted by the IPCC itself or by the knowledge holders and research communities who generate the literature on which the IPCC relies.
Nominations for the workshops are welcome from knowledge holders, practitioners, and scientists with the relevant expertise.
For the Workshop on Engaging Diverse Knowledge Systems, this would be expertise on the application and interpretation of diverse forms of knowledge, including:

With great sadness, the Intergovernmental Panel on Climate Change (IPCC) has learned of the death of Dr Mannava V.K. Sivakumar, who passed away on 30 March 2025 in Hyderabad, India.
Dr Mannava Sivakumar, fondly known as Shiv, was the Acting Secretary of the IPCC from January to June 20I6, the early stages of the sixth assessment cycle. During this time, Dr Sivakumar oversaw the organization of the 43rd Session of the IPCC, where the Panel decided which Special Reports it would work on in the sixth cycle.
He was the Director of the Climate Prediction and Adaptation branch of the World Meteorological Organization (WMO) from 2010 to 2012 when he retired. From 1998 to 2010, he was the Head of WMO’s Agricultural Meteorological Division.
Dr Sivakumar received the 2007 International Service in Agronomy Award of the American Society of Agronomy, which recognizes outstanding contributions in research, teaching, extension, or administration made outside of the USA by an active agronomist.
Before joining WMO he worked at the International Crops Research Institute for Semi-Arid Tropics (ICRISAT) where his highest position was Principal Agricultural Climatologist at ICRISAT’s Sahelian Centre in Niamey, Niger.
Dr Sivakumar was born on 30th August 1950 in Guntur, Andhra Pradesh, India. In 1970, he graduated from the Agriculture College, Bapatla, where he had studied since 1966. He completed his Master’s degree at the Indian Agricultural Research Institute in New Delhi in 1972 and obtained his Ph.D. from Iowa State University in 1977.
GENEVA, Mar 24 – Over 100 experts from more than 40 countries are meeting in Bilbao, Spain this week for the first meeting of authors and review editors of the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers (SLCF). This will be the first methodology report released by IPCC in the seventh assessment cycle and it is being prepared by the Task Force on National Greenhouse Gas Inventories (TFI).
The 2027 Methodology Report is expected to provide guidance on anthropogenic emissions for Short-lived Climate Forcers, not including secondary human-induced substances.
“The report aims to provide clear guidance on measuring emissions from key short-lived climate forcing substances, including nitrogen oxides, carbon monoxide, and others, which significantly contribute to global and regional air quality and climate change,” said Takeshi Enoki, one of the Co-Chairs of the TFI.
This week´s meeting in Bilbao marks the beginning of the drafting process of this Methodology Report which is scheduled to be released in March 2027. The Coordinating Lead Authors and Lead Authors at this meeting will start developing the report based on the outline agreed by the Panel during its 61st Session held in Sofia, Bulgaria in July/August 2024.
“We are excited to begin work on this report with a diverse group of experts selected from the 394 nominations we received. Their work will be important for enhancing the data used in climate models,” said Mazhar Hayat, TFI Co-Chair.
Following the Panel’s 61st Session, the IPCC called for nominations of experts to act as Authors and Review Editors of the 2027 Methodology Report in August 2024. The TFI Bureau, also known as the Task Force Bureau, in consultation with relevant Working Group Co-Chairs selected the report’s Coordinating Lead Authors, Lead Authors and Review Editors. In their selection, they considered scientific and technical expertise, geographical and gender balance in line with Appendix A to the Principles Governing IPCC Work.
A preliminary list of the Authors for the 2027 Methodology Report is available here.
Following the Lead Author Meeting, there will be an outreach event hosted by the Spanish Climate Change Office at the Bizkaia Aretoa in Bilbao on 27 March 2025. More details on the event are available here.

GENEVA, Mar 21 – The Intergovernmental Panel on Climate Change (IPCC) is inviting its member governments and accredited observer organizations to nominate experts to serve as Co-Chairs and members of the Task Group on Data Support for Climate Change Assessments (TG-Data). A call for nominations of experts by governments and observer organizations to serve as TG-Data members has been launched. Nominations should be submitted by Thursday 17 April 2025 (midnight CEST).
The final selection of TG-Data members will be undertaken by the IPCC Bureau.
The IPCC Task Group on data support provides guidance to the IPCC’s Data Distribution Centre on the curation, traceability, stability, availability and transparency of data and scenarios related to IPCC reports.
The TG-Data work mainly requires but is not restricted to data specialists, with a particular expertise in areas such as data provenance, scientific workflows, climate data handling systems, FAIR (Findable, Accessible, Interoperable, Reusable) Data principles, and development and/or analysis of climate and observational datasets.
TG-Data membership is renewed with the author selection process of a new assessment IPCC report. Following the agreement on the outlines of the three Working Group contributions to the Seventh Assessment Report reached at the Panel´s 62nd Plenary last month, the IPCC is currently calling for the nomination of authors for these three Working Group contributions.

What is the IPCC?
The Intergovernmental Panel on Climate Change (IPCC) is the UN body for assessing the science related to climate change. It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988 to provide political leaders with periodic scientific assessments concerning climate change, its implications and risks, as well as to put forward adaptation and mitigation strategies. In the same year the UN General Assembly endorsed the action by the WMO and UNEP in jointly establishing the IPCC. It has 195 member states.
Thousands of people from all over the world contribute to the work of the IPCC. For the assessment reports, scientists and experts volunteer their time as IPCC authors to assess the thousands of scientific papers published each year to provide a comprehensive summary of what is known about the drivers of climate change, its impacts and future risks, and how adaptation and mitigation can reduce those risks.
The IPCC has three working groups: Working Group I dealing with the physical science basis of climate change; Working Group II, dealing with impacts, adaptation and vulnerability; and Working Group III, dealing with the mitigation of climate change. It also has a Task Force on National Greenhouse Gas Inventories that develops methodologies for measuring emissions and removals.
IPCC assessments provide governments, at all levels, with scientific information that they can use to develop climate policies. IPCC assessments are a key input into the international negotiations to tackle climate change. IPCC reports are drafted and reviewed in several stages, thus guaranteeing objectivity and transparency.
About the Seventh Assessment Cycle
Comprehensive scientific assessment reports are published every 5 to 7 years. The IPCC is currently in its seventh assessment cycle, which formally began in July 2023 with the elections of the new IPCC and Task Force Bureaus at the IPCC’s Plenary Session in Nairobi.
At its first Plenary Session in the seventh assessment cycle – the 60th Plenary Session in Istanbul, Türkiye, in January 2024 – the Panel agreed to produce in this cycle the three Working Group contributions to the Seventh Assessment Report (AR7), namely the Working Group I report on the Physical Science Basis, the Working Group II report on Impacts, Adaptation and Vulnerability and the Working Group III report on Mitigation of Climate Change. The Synthesis Report of the Seventh Assessment Report will be produced after the completion of the Working Group reports and released by late 2029.
During its 62nd Plenary Session held in Hangzhou, China, in February 2025, the Panel agreed on the outlines of the three Working Group contributions to AR7.
The Panel decided already during the previous cycle to produce a Special Report on Climate Change and Cities and a Methodology Report on Short-lived Climate Forcers during AR7. Scientists have also been asked to deliver a Methodology Report on Carbon Dioxide Removal Technologies, Carbon Capture Utilization and Storage.
At the IPCC’s 61st Plenary Session held in Sofia, Bulgaria, from 27 July to 2 August 2024, the Panel agreed upon the outlines for the Special Report on Climate Change and Cities scheduled for approval and publication in March 2027 and for the 2027 IPCC Methodology Report on Inventories for Short-lived Climate Forcers scheduled for publication in the second half 2027.
In addition, a revision of the 1994 IPCC Technical Guidelines on impacts and adaptation as well as adaptation indicators, metrics and guidelines, will be developed in conjunction with the Working Group II report and published as a separate product.
IPCC’s latest report, the Sixth Assessment Report, was completed in March 2023 with the release of its Synthesis Report, which provided direct scientific input to the First Global Stocktake process under the United Nations Framework Convention on Climate Change at COP28 in Dubai.
The Sixth Assessment Report comprises three Working Group contributions and a Synthesis Report. The Working Group I contribution Climate Change 2021: the Physical Science Basis was released on 9 August 2021. The Working Group II contribution, Climate Change 2022: Impacts, Adaptation and Vulnerability, was released on 28 February 2022. The Working Group III contribution, Climate Change 2022: Mitigation of Climate Change, was released on 4 April 2022 and the Synthesis Report on 20 March 2023. The Synthesis Report to the Sixth Assessment Report, distils and integrates the findings of the three Working Group assessments as well as the three Special Reports released in 2018 and 2019.
The special reports were on Global Warming of 1.5°C (October 2018.), Climate Change and Land (August 2019) and, the Ocean and Cryosphere in a Changing Climate (September 2019).

About the IPCC Scholarship Programme
The IPCC Scholarship Programme was established with the funds received from the 2007 Nobel Peace Prize, supplemented by generous contributions from other donors.
The Programme was further made possible through generous contributions by governments, its long-standing funding partners, organizations and individuals. The first partner of the Programme was Gro Harlem Brundtland, former Norwegian Prime Minister and UN Special Envoy on Climate Change. Funding support was provided by the Governments of Germany and Norway. Other individuals and organizations that have supported the programme over the years, include Aster Finance, Cheng Fa Qing, Jean-Pascal van Ypersele (Chair of the Board of Trustees), Hoesung Lee (former IPCC Chair), The AXA Research Fund, Dickinson College, The Prince Albert II of Monaco Foundation and The Cuomo Foundation.
Twenty-four students from developing countries and countries with economies in transition were awarded IPCC scholarships in the Seventh round (2023-2025). Since the first awards in 2011, a total of 116 students have been supported.
GENEVA, Mar 11 – The Intergovernmental Panel on Climate Change is calling for nominations of experts to act as Coordinating Lead Authors, Lead Authors, or Review Editors for the three key Working Group contributions to IPCC´s Seventh Assessment Report (AR7). This follows the Panel’s agreement on the outlines of the three Working Group contributions during its 62nd Session held in Hangzhou, China.
Hundreds of experts around the world in different scientific domains volunteer their time and expertise to produce the reports of the IPCC. Author teams reflect a range of scientific, technical and socio-economic expertise. Coordinating Lead Authors and Lead Authors are responsible for drafting the different chapters of the Working Group contributions to the AR7 and, with the help of the Review Editors, revising those based on comments submitted during the two rounds of reviews by experts and governments.
“Our priority for the Seventh Assessment Report is to attract the most talented individuals across the whole spectrum of scientific, technical and socio-economic research. We would like to see balanced author teams involving both established experts and younger scientists new to the IPCC. It is essential that we reflect fully the breadth and depth of knowledge on climate change and climate action” said IPCC Chair Jim Skea.
IPCC author teams include a mix of experts from different regions to ensure geographic balance. The IPCC also seeks a balance in gender, as well as between those experienced with working on IPCC reports and those new to the process, including younger scientists.
During the 60th Session of the IPCC in January 2024, the Panel agreed to continue to prepare a comprehensive assessment report and to maintain the current Working Group structure where Working Group I assesses the scientific aspects of the climate system and climate change; Working Group II looks at impacts, adaptation, and vulnerability to climate change, and Working Group III assesses the mitigation of climate change.
The outlines of the three Working Group contributions to the AR7 were developed after a comprehensive scientific scoping meeting in December 2024 in Kuala Lumpur, Malaysia before the Panel considered them and agreed upon them at the end of February.
Those interested in being nominated as a Coordinating Lead Author, a Lead Author or a Review Editor should contact their relevant Focal Point. A list of Focal Points for IPCC member governments and observer organizations is available here.
Nominations are submitted through a dedicated online nomination tool by Focal Points in governments and accredited observer organizations, as well as IPCC Bureau Members.
Governments, Observer Organisations, and IPCC Bureau Members have been requested to submit their nominations by Thursday 17 April 2025 (midnight CEST).
More information on the nomination process is here and how the IPCC selects its authors is available here.
