They also like to muddy the waters, climates change, because climates aren't even a thing, but an aggregate, obviously. Anthropogenic climate change, is what's being questioned, and that there is no certainty that it will cause disasters any more so than if there was still 300ppm CO2 in the atmosphere. Maybe 400ppm is bad, doesn't seem so tho, we are living the experiment.
BUT also, I would bet Air Conditioners are far worse for the planet than 400ppm CO2, even if they act together. ACs, are, absolutely abysmal thermodynamically. Heating up one space to make another space colder temporarily, with high likelihood of CO2 release.
Slight tangent. Have you heard the sixth Dimmu Borgir album? Good stuff. https://www.youtube.com/watch?v=TFRwNYPsHwY
I wonder will it generate any discussion, or just be castigated via downvotes, your choice.
