Number of people living in extreme heat to double by 2050 if 2C rise occurs, study finds

A new study indicates that if global temperatures rise by 2C, the number of people living in extreme heat will more than double by 2050, affecting 41% of the projected global population. The authors assert that no region will be immune to the impacts, with the tropics and southern hemisphere facing the worst effects, while northern countries will struggle to adapt due to their infrastructure being designed for cooler climates.
