They don’t talk about global warming anymore,” Epstein said. “They talk about climate change, and it turns out that carbon dioxide is a very weak driver of climate change. […] There’s so many solar phenomena out there which make a great deal more … remember, Greenland was green when it was taken over. […] It wasn’t global warming that made those places warm and cold. hat you have to understand is given these huge cycles that we’ve had over the last even 10,000 years, this global warming stuff is, you know, doesn’t matter very much relative to the other forces that we don’t understand them. You could spend fortunes in time wasting your efforts stopping things that may never occur t’s very difficult to hit the sweet spot of spending money which isn’t wasted either way. Either, of course you don’t need it, or because even if you do it the Armageddon’s going to happen anyhow.
