Sucks when it actually gets hot though. Lots of places either don't have AC or if they do, they keep it something approaching 85 degrees, which is ok if you're not hot to begin with and you have a fan, but when you're trying to sleep or after you've already gotten hot and sweaty, doesn't really cool you down comfortably, or at least not by our standards.
Of the 6 million AC's sold in Europe in 2016, 88% were residential ductless mini splits... Likely only cooling bedrooms. Only 700,000 were into the commercial market segment. For comparison, in the US in 2016 we had 6.5 million commercial AC systems sold. Considering the population difference of 741 million vs 328 million, the net effect is there are more than 20 times more commercial AC units in the US than in Europe. So when you are in a commercial building (restaurant, store, office, school, etc) in the US in July, odds are you are sucking in cool dry recirculated AC air. In Europe, odds are there is a nice cool breeze of fresh air coming in an open window or there is a fan on you.
Johnson.. You are one of the better people I have seen on here in seeing truth in data. You interested if I start plotting some data on 30-40 countries in the northern hemisphere based on climate/AC penetration/case counts/deaths will you take a look? As I look at the countries that are having big spikes in cases/deaths in the northern hemisphere (Southern US, India, Israel, Saudi Arabia, Iran, Iraq, Egypt, Mexico, Russia, Indonesia, and more) the number one thing I can correlate is that they all seem to be hot as balls and people are congregating around the AC.
I also hypothesize that the worm will turn when the weather gets cold, because the hot climates will open a window and the colder ones will crank up the forced air heat and get inside to beat the cold.
Here's the link to the AC data I am using if anyone is interested.
