Better yet, ask them how much of the atmosphere is made up of this deadly carbon dioxide stuff. Most don’t understand this bullshit theory is that .00041 of the atmosphere is controlling global climate when. At the same time these religious fanatics, masquerading as real scientists, just completely ignore the 2-4% of the atmosphere made of of water vapor, which is actually what causes the “greenhouse” effect that allows life on earth. The amount of flat-earth bullshit about anthropogenic climate change is astounding. It is a massive grifting industry. I don’t know what will end it, but clearly the truth, science, facts and 40 years of failed hypothesis and failed predictions are not enough.
