Figure 9.13 | Temperature increases due to human-caused climate change are detected across Africa and many regions have warmed more rapidly than the global average. Mean observed trends in (a) average temperature (°C per decade) and (b) average precipitation in (mm per decade) for 1980–2015. Trends were calculated with respect to the climatological mean over 1980–2015. The Climate Research Unit Time Series data (CRU TS) are used to compute temperature trends using 2-m temperature and the Global Precipitation Climatology Centre data (GPCC) precipitation trends. Regions with no cross-hatching indicate statistically significant trends over this period and regions in grey indicate insufficient data. The figures are derived from Gutiérrez et al. (2021).
