Extreme Heat Events are Getting More Extreme

As the Earth’s climate warms, hotter-than-usual days and nights are becoming more common, and heat waves are expected to last longer and become more frequent and intense.

Even small increases in these extreme heat events can lead to more heat-related illnesses and deaths.
