Heatwaves may affect up to 2.8 billion people worldwide by 2090, UN Migration Agency says

Up to 2.8 billion people could be exposed to heatwaves globally by 2090 in a high-warming scenario, according to a report Tuesday by the International Organization for Migration (IOM).

This scenario predicts a significant rise in global temperatures due to increased greenhouse gas concentrations. The report says almost half of those potentially affected by heatwaves, up to 1.3 billion, are projected to live in Southern Asia.

IOM emphasizes that by taking appropriate measures to reduce warming, the number of people at risk could be more than halved.
