Essentially, wherever AC gets rolled out, heat-related death plunges. Taking Barreca’s estimate and applying it to Europe suggests that as many as 100,000 European lives — 0.013% of the population — could be saved every year if the 80% of European households who don’t have AC were to get it. Is the effect strong enough to show up in life expectancy tables? Average lifespan is already quite a bit longer in much of Western Europe than the US (https://old.reddit.com/r/dataisbeautiful/comments/1lih4a0/oc_life_expectancy_in_europe_compared_to_the_us/ https://old.reddit.com/r/dataisbeautiful/comments/1lih4a0/oc...) that it surprises me that this would push it even farther. Am I wrong to be skeptical? For that matter, does it show up in differences between US states? Personally I've lived in 9 different states, 4 which are in the top ten for life expectancy, and I haven't had central air conditioning in any of them. Is this an anomaly? Is there any correlation between air conditioning use within the US and life expectancy?
