Air-Conditioning Is “a Critical Adaptation” that Saves Lives

(p. A3) Air-conditioning is not just a luxury. It’s a critical adaptation tool in a warming world, with the ability to save lives.
. . .
In our continuing research, my colleagues and I have found that hot days in India have a strikingly big impact on mortality. Specifically, the mortality effects of each additional day in which the average temperature exceeds 95 degrees Fahrenheit are 25 times greater in India than in the United States.
. . .
The effect of very hot days on mortality in the United States is so low in part because of the widespread use of air-conditioning. A recent study I did with colleagues showed that deaths as a result of these very hot days in the United States declined by more than 80 percent from 1960 to 2004 — and it was the adoption of air-conditioning that accounted for nearly the entire decline.
