Fig. 6: Annual trends in heatwave metrics for AHWs and LHWs under future emission scenarios (Shared Socio-economic Pathway (SSP): SSP126, SSP370, SSP585), calculated with a fixed 2000–2022 baseline.

The left panel depicts the AHW trends, and the right panel shows the corresponding LHW trends. Hist conditions (2000–2022) are shown as a black line; SSP126, SSP370, and SSP585 for 2023–2100 are shown as green, blue, and red lines, respectively. Shading denotes the 25–75th percentile range. From top to bottom, the metrics are a, b accumulated heatwave days, c, d mean intensity, e, f reoccurrence period, g, h CHI, i,j CHIP, and k, l heatwave frequency.
