Have you tried to nap when the temperature outside is 41c and you have no air conditioning? I have. It is not possible.
Where I live, we hit 46c last year. I brought a portable AC to my mom, it was 32c in her 2nd story bedroom after sunset. Yeah of course those temps are not unheard of in some regions. But I am north of the 45th parallel. It isn’t normal and a “siesta” won’t make it so.
We fucked up, the planet is getting hotter. We need to adapt. Where I live, electricity is mainly generated through hydroelectric dams. Yeah, it fucks up the fish, but it is better than coal or methane. And yes, I will unabashedly run my AC to make my home habitable. It isn’t accepting defeat, it is allowing us to live.
I wonder, as you wrote this reply, what was the temperature inside your home? I am sure you will tell us with the same zeal that was behind your original reply. If not, kindly keep your “customs” to yourself while people die of heat sickness in their homes.
