When Globull warming first came to my attention as a friend asked me about it (I had heard of it of course and knew it was a lie) and I did some research. The original people who invented it lied, and knew they lied, and a whistleblower went public and explained that. This was maybe 18 yrs ago or so??

I first encountered speculation about the "Greenhouse effect" in the 1966 popularization of science by the great science fiction writer, Isaac Asimov: Understanding Physics.
There is no doubt in my mind that Asimov was deliberately fed this story for inclusion in the book. It might even have been the real reason for coming out with a book that was so far off of Asimov's normal playing field.
