So they will be murdering hundreds if not thousands of people per year.

According to the Arizona Department of Health Services, at least 4320 people died of heat related illness in 2023 and 2024 combined. 2/3 of Arizona lives in Phoenix, so that's around 1400 people per year already. 3⁰C extra will be catastrophic.

People will come back to houses with their loved ones boiled to death because the AC broke and the repair service wouldn't risk their life sending anyone out there. People will have engine failure and die on the side of the highway before AAA can arive. Fire risk is also going to increase to absurd levels so entire neighborhoods might well burn down.

I really hope this is going to be enough to start a revolution, because that is going to be hell.
