There's a very small part of me that wants to see all their scheming bullshit succeed just so when it all collapses they have to accept the truth. But the reality is they'd just blame Obama or take credit for changing things for the better.
Trump is old and will likely die before any extremely severe consequences manifest themselves (other than all these hurricanes). He took advantage of small towns across the U.S. wanting the good old days so he could become the most powerful man in America, and in his eyes, above the law. Hell, he tried to spin the hurricanes as some sort of good team-building exercise. He is a psycopath.
Don't be fooled, none of these older climate change deniers will face the consequences. If they had to look beyond the 10-20 years they had left, they'd sing a different tune.
