How Europe Became the World Champion of Heat Deaths
25th June 2026
Here is a trivia question: which continent suffers the most heat-related deaths per capita? By a wide margin, the dubious prize goes to… Europe. In the summer of 2022 alone, more than 61,000 Europeans died as a result of the heat.
In case you feel geographically confused: no, the equator does not run through Brussels. Thanks to its northern latitude, Europe in fact endures fewer heat days than almost any other inhabited region on Earth. How, then, can it hold the record for heat mortality? Part of the story is of course demographic. Europe has one of the oldest populations in the world, and the elderly are far more vulnerable to high temperatures. But age explains only a sliver of the gap. The United States is greying too, and Japan is older still than both—yet the risk of dying from heat in either country is dramatically lower.
The real explanation comes down to two letters Europe stubbornly refuses to learn: A/C. Across the continent, only about a fifth of homes have air-conditioning, against nearly 90 percent in the United States and more than 90 percent in Japan.
Sometimes it surprises me that European countries even allow flush toilets.
