People Exposed to Climate Change: Asia
December 2024 to February 2025
Temperature anomalies
-
The last three months were warmer than normal for 37 out of the 51 countries analyzed in Asia, averaging 0.6°C above the 1991-2020 normal.
-
Kazakhstan, home to more than 20.4 million people, experienced the highest average temperature anomaly across Asia — 1.8°C above the 1991-2020 normal.

Days with unusual heat made twice as likely by climate change
-
Over the last three months, nearly 554 million people across 10 countries in Asia experienced daily average temperatures that were strongly influenced by climate change (defined as CSI 2 or higher) for at least one-third of the season (30 or more days).
-
Around 455,000 people in Brunei Darussalam experienced 83 days over the past three months with a strong climate change influence.

Risky heat days 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).
- More than 45 million people across the continent were exposed to at least 30 risky heat days that were added by climate change.
