Yeah, I mentioned earlier, Europe doesn't have much AC (if at all, really). That's very much an American thing. We never really planned for global warming either, most of our building were built 10-20years ago, and our cities are hundred years old. Narrow road, "no car" town areas, that kind of stuff. They build now with better isolation and solar panel, but it's recent. And old part of town are historical, so it's a nightmare to put "new technology" stuff.
The Mediterranean coast was used to have hot summer. 40°c was not unusual in Italy, Spain or south of France. And people adapted to that. They built differently (lots of shadowse for the streets, for example). The siesta, to sleep during the worst of the day, or Spain open its store much later in the day, and eat dinner around 9-10pm, when it's cooler.
But the 40°c didn't last for weeks, months even. And that's quite difficult.
It's even worse for countries like Sweden. Last year a Finnish guy said he had 30°c, while in Finland summer are at most 25°c (which they find hot). Poor dude was red and suffering. Those countries have always build for cold, not heat.
