First off, the only reason “extreme” temperature kills more people than other weather hazards is that deaths from weather have plummeted over the century, even as doomsday climate warnings about heat, hurricanes, tornados, floods, and droughts have spiked. Extreme weather accounts for only about 0.1 death for every 100,000 people in the United States each year. The Post should be celebrating the fact that humans have never been less threatened by the climate.
