The south already mostly had AC. The north was too busy criticizing the south for things like closing shops in the afternoon, using blinds, eating late, and of course using AC. Now I guess they're beginning to realize that maybe it's not that the south is "lazy" but just adaptation.

Toning down the snark, to be honest, most places in countries like France and Germany didn't have AC because up to a few years ago, maybe they'd seriously need it one week per year or so... it didn't make sense for them to have it just to keep it turned off 99% of the time. I'm sure they will adapt, but it always takes some time to change the old ways.

When the temperature in Berlin is higher than 30degC, it becomes the south. People start to shout, honk, argue in the streets, stay up late.

We are affected by the weather much more than we'd like to admit.
