ECMWF & The Copernicus Programme
A new study published in Nature Climate Change uses the Copernicus Climate Change Service’s (C3S) ERA5-HEAT dataset to provide a comprehensive global-scale analysis of how heat stress has evolved since 1950. Using the Universal Thermal Climate Index (UTCI), the study shows that hazardous heat is becoming more frequent, more intense and more widespread, with hotter nights, longer heat stress seasons and increasing numbers of people exposed to hazardous heat.
