A 1980 heat wave directly killed 1,260 people, and heat stress contributed to an estimated 10,000 deaths. That’s almost twice as many people as were killed directly by Katrina, Sandy, the Camp fire and also the 9/11 terrorist attacks — combined.
led by Duke University researchers estimated that during the last decade, the Lower 48 states averaged 12,000 heat-related premature deaths each year.
There’s no question climate change is making extreme heat worse, and will continue to do so as long as we keep burning fossil fuels and cutting down forests. Already, major U.S. cities are experiencing three times as many heat waves as they did in the 1960s, with a heat wave season that is 47 days longer now than it was then,“Heat waves are different than floods and hurricanes, because floods and hurricanes affect physical infrastructure. And so they’re visible.
The researchers found that while Americans aren’t super worried about extreme heat overall, risk perceptions vary by geography and demographics. Areas with more residents over age 65 express relatively less worry about extreme heat, even though elderly people are among the most vulnerable. And areas with more Latino, low-income and female residents tend to be more concerned than whiter, wealthier and more male communities.
Marlon said those latter findings track with other research showing that men — white conservative men, in particular — tend to have lower risk perception in general. They also track with surveys showing that Latinos arePerhaps not surprisingly, Marlon and her colleagues found that people living in the warmer southern half of the U.S. see extreme heat as a greater risk than their counterparts to the north.
Why does this stuff matter? Because if we were all sufficiently worried about heat waves, we might be more likely to take precautions, like drinking enough water or avoiding strenuous activity. And governments might be more likely to take on systemic interventions, such as
