Leftist Infighting: A community dedicated to allowing leftists to vent their frustrations

I know very little about this subject. I had someone I know tell me a few months ago that for socialism to be sustainable, and to solve the climate crisis, U.S.ians are going to need to give up almost all A/C. They pointed out the fact that Amerikans are crybabies and even most of Western Europe does not use A/C.

However, with Greece and Spain recently having caught on fire and with heat waves devouring the nations, as well as stories regarding people in hotter regions in the U.S. dying from heat stroke in their own homes because they couldn't afford their electricity bills, this read as sort of Maoist-lite, petty-bourgeois radicalism to me shifting blame on individuals when there are so many systemic industries contributing astronomically to the worsening climate. I was wondering, is A/C usage so detrimental as to necessitate its destruction? Should not the focus be on larger, more destructive industries and actually increasing the availability and affordability of A/C to hotter regions? Should scientific focus be moreso on creating a green A/C?

Like I said, almost no knowledge. Feel free to roast my ass (pun slightly intended).
