Republicans (and the equivalent rich conservatives in other countries) believe that climate change is happening anyway, and that anyone who doesn't try to make money off it is an idiot. They don't buy the survival of the human civilization bit - they think it'll affect only poor people, and that the rich will be safe. And honestly, they're right, at least for what we'll see in their lifetimes. Poor people are going to die in their millions in the coming decades, and rather than seeing themselves as the cause of this they see themselves as protecting themselves and their friends and families against it by insulating themselves with money.

That's my theory anyway.
