Skimmed through this, but I can't make it all the way. It's so jarring and too depressing. I lump climate change deniers into the same category as flat-earthers. Although I have more respect for the latter, as at least they aren't blindly swallowing self-serving nonsense spewed by ignorant politicians and certain news outlets.
I don't think there are scientists who deny past or present climate change. Do you mean to disparage the many scientists who research the causes of past climate change, and who hypothesize that the current changes are, like all past changes, caused by other factors than the man-made, industrial-age rise in atmospheric carbon dioxide?
The scientists who claim "current changes are, like all past changes, caused by other factors than the man-made" are not taken seriously by the mainstream, form an unimaginably slim minority and frankly are dangerously wrong.
