Heat waves are the single most deadly natural disasters the nation faces each year, killing more people than hurricanes, tornadoes, floods, blizzards or extreme cold. At least 289 people died in the heat dome that hit Washington, Oregon and California in June 2021 alone, according to the National Oceanic and Atmospheric Agency. At its peak, on June 28, there were 1,090 heat-related illness visits to emergency rooms in the region, according to the CDC. The problem is expected to worsen in coming years as climate change increases heat waves' frequency and temperatures. July 2021 was the hottest month ever recorded on Earth and US summers are becoming hotter and deadlier, according to NOAA. Visit the LINK IN BIO for tips on keeping cool in the heat.
