I have read 38 books to date on global warming/climate change, etc. A lot of the authors started out just investigating it, and decided it was untrue, a hoax. The other authors were experts in the field of meteorology etc and they never believed in the hoax of human cause of climate change. I keep my books on the top shelf of a bookcase for easy reference. Authors like Brian Sussman, James Inhofe, Larry Bell, etc.
Of course it’s nothing but a hoax
