Fig. 3

a The global spatial patterns of the average annual population exposure to CHUV events during the 2010s. Colors from light to dark red indicate increasing population exposure (10⁴ people). b The historical and future estimates of global total population exposure to CHUV events annually. Lines represent: Hist (gray line), ERA5 (light green line), CMIP6 (light blue line), SSP126 (blue line), SSP370 (orange line), and SSP585 (red line). Shading indicates ±1 standard deviation. c Top 10 vulnerable countries with the most population exposure to CHUV events in the 2010s. Error bars indicate ±1 standard deviation. d Average annual population exposure in different age groups in the 2010s and under future scenarios (2070–2099). Bars represent the working-age group (15–64 years; light blue bars) and the elderly group (≥65 years; light red bars). Error bars indicate ±1 standard deviation. Note: the population exposure here refers to the total number of people across all grid cells that experience the occurrence of CHUV events.
