As it says here, when Donald Trump is inaugurated, he will become the only major world leader who denies Climate Change and wants to roll back efforts to combat it.
If you leave aside the human and property damage that may result — no small matter to leave aside — the horrifying part of it is that he bases his position on no science whatsoever. I don't think he even pretends to. This is a man who couldn't build a model volcano out of baking soda and vinegar. Maybe he's listening to some crackpot denier with no real credentials. More likely, he's listening to industry leaders who moan about how regulations cut into their immediate profits.
Back when one of those Bush guys was in the Oval Office, my Business Manager and I were having lunch and he mentioned some regulation that the president had just managed to get lifted or was about to get lifted. My Biz Guy said, "The problem with this administration is that even if some public good is important, it's never as important as someone rich becoming richer."
That was true then but not as true as it's going to be.
