Even when it seems obvious that extreme heat was a factor, death certificates don’t always reflect the role it played. Experts say a mishmash of ways more than 3,000 counties calculate heat deaths means we don’t really know how many people die in the U.S. each year because of high temperatures in an ever warming world.

That imprecision harms efforts to better protect people from extreme heat because officials who set policies and fund programs can’t get the financial and other support needed to make a difference.

“Essentially, all heat related deaths are preventable. People don’t need to die from the heat,” said epidemiologist Kristie L. Ebi, who focuses on global warming’s impact on human health as a professor at the University of Washington.

With a better count, she said, “you can start developing much better heat wave early warning systems and target people who are at higher risk and make sure that they’re aware of these risks.”

Currently, about the only consistency in counting heat deaths in the U.S. is that officials and climate specialists acknowledge fatalities are grossly undercounted.

......

the Centers for Disease Control and Prevention reports just 600 to 700 heat deaths annually in the United States. A study published last month in the journal Nature Medicine estimated more than 61,000 heat-related deaths last summer across Europe, which has roughly double the U.S. population but more than 100 times as many heat deaths.
