More people died of heat last year than from any other weather disaster, statistics from the National Weather Service show.
For 2021, 190 heat-related deaths were reported in the U.S. The next-highest weather-related killer was flooding, which was responsible for 146 deaths.
According to a technical paper from the Environmental Protection Agency, extreme heat events have become more frequent in the United States in recent decades, and studies project that the frequency and intensity of extreme heat events will continue to increase as a consequence of climate change.
