Yeah the discourse tends to be very binary on this and everything else. I don't use my AC if I can avoid it because I prefer to get used to the heat, and let my body adjust, but there are limits on how how it can get where that's even feasible to do. We should probably use the AC as little as we can manage, because it uses energy to do and that leads to more CO2, but then people take that exhortation to reduce and say "what you want poor and sick and old people to die in the heat?" Which no, obviously not.

Most people's bodies can adjust to hotter temps than they think, and probably don't need as much cooling as they realize. And by staying in overcooled buildings all summer, it makes your body less adjusted to high heat when you do have to go out. So that's one side of things.

On the other side you have places that are simply not survivable anymore without climate control. So it's ridiculous to think anyone is in favor of banning AC.

The problem is when we invented AC, the design of our buildings changed. Older buildings used to be designed to keep themselves cooler passively and with air flow. More modern buildings don't have that because they just rely on air conditioning to keep the temperature in check, so what we need is better buildings and a rethinking of our infrastructure to minimize energy requirements especially as the climate heats up.

The two positions are only mutually exclusive if you're willfully obstinate.
