Actually the way to shut up the Gorebull fanatics when they get testy like this is to ask them “What is the percentage of CO2 in the atmosphere?” When they say something absurd like 30%, you say “Noooo, it’s ZERO POINT ZERO baby! 0.04% to be exact! You are buying into a scam that has you believing that a gas that makes up ZERO POINT ZERO in the earths atmosphere is somehow raising the temperature of 5000 trillion tons of atmosphere! So STFU!”
I just reply to their every statement with “Baaa, Baaa.”
When they finally look confused, I just call them a sheeple and move on.
