(p. A15) Globally, a recent Lancet study found 4.5 million cold deaths, nine times more than global heat deaths. The study also finds that temperatures increased half a degree Celsius in the first two decades of this century, causing an additional 116,000 heat deaths annually. But warmer temperatures now also avoid 283,000 cold deaths annually. Reporting only on the former leaves us badly informed.
. . .
Even if all the world’s ambitious carbon-cutting promises were magically enacted, these policies would only slow future warming. Stronger heat waves would still kill more people, just slightly fewer than they would have. A sensible response would focus first on resilience, meaning more air conditioning and cooler cities through greenery and water features. After 2003’s heat waves, France required air conditioning in nursing homes, reducing heat deaths tenfold despite higher temperatures.
