Scientists warn that reaching 2°C global warming could make areas too hot for humans, affecting a third of land by 2070.

Scientists warn that global warming reaching 2°C could triple the area too hot for humans, equivalent to the size of the U.S. People in North Africa and South Asia face the highest risk, with unsafe temperatures affecting 6% of land for younger adults and a third for those over 60. Between 1994 and 2023, unsafe heat and humidity levels affected 2% of land for younger people and 20% for older individuals. The study, published in Nature Reviews Earth and Environment, highlights the need to limit warming to below 2°C to avoid deadly consequences.
