I think it would be helpful for many people to experience the world without the luxury of ac. It uses a huge amount of power and in most places it's just a convenience. I haven't run the AC in something like 18 months not. It's been in the upper 90s here in the states and my house has gotten up to about 86 inside. I work outside so even a few degrees cooler feels great. At night with a couple fans in the window it goes back down to mid 70s.
I understand that some places get a lot hotter and corporations are to blame for a larger percentage of our climate issue, but we shouldn't expect to live in luxury while the planet catches on fire around us. All that said I think people would give more of a fuck if they didn't sit around all day in a climate controlled environment.
You're probably right, better just put my head back in the sand and hope the world burns down around me and leaves me in tact. Guess there's nothing we can do.
