Except when we have 100% renewable low emission electricity and transition away from CFC refrigerants, they’ll essentially drop to zero emissions. There’s nothing particularly bad about air conditioning. It is more and more becoming a necessity for survival due to climate change. If you don’t like that, your target is the fossil fuel industry, not the working class people who use air conditioning to avoid suffering.

Meanwhile, animal agriculture will always be extremely harmful to the environment due to methane, nitrous oxide, and various other issues. I’m happy for you to criticise people for using air conditioning if you’ll commit to going vegan.
