Heat-Related Deaths Surge in the U.S. Amid Rising Temperatures

New study reveals a significant increase in fatalities linked to extreme heat, with California, Arizona, Nevada, and Texas hardest hit.

Over 21,500 heat-related deaths have occurred in the U.S. since 1999, with a sharp rise since 2016.
2023 recorded the highest number of heat-related deaths in over two decades, at 2,325 fatalities.
Researchers warn that the actual number of deaths is likely undercounted due to inconsistent reporting practices.
Experts call for enhanced infrastructure, such as cooling centers and hydration stations, to mitigate the impact of extreme heat.
Local and national authorities are urged to increase efforts in heat surveillance and public awareness.
