Days with unusual heat made twice as likely by climate change

Risky heat added by climate change
Risky heat days are days with temperatures hotter than 90% of temperatures observed in a local area over the 1991-2020 period. Heat-related health risks rise when temperatures climb above this local threshold. This is a conservative approximation of the local minimum mortality temperature (MMT), an indicator of the local links between temperature and mortality based on peer-reviewed research by Tobias et al. (2021) and Gasparrini et al. (2015).
- From December 2024 to February 2025, the Indian state of Kerala, home to more than 42.8 million people, saw nine risky heat days - more than any other part of the country.
