Fig. 2: Changes in return periods of a 1-in-100-year season in the 748 locations.

Changes in return periods for the climate of 2020 (warming level of 1.2 °C, a), at 1.5 °C warming (b) and at 2.0 °C warming (c) compared to the risk in the climate of 2000 (0.7 °C warming). The figure displays the new return period of the location-specific 1-in-100-year heat-mortality level of 2000. The colour-scale is logarithmic. The grey dots denote locations with inconclusive results due to their spread in uncertainty.
