This is the stupidest thing about climate change denial: most of it is motivated by the notion that ignoring the problem/continuing to exploit fossil fuels is cheaper/more profitable, but it really isn't. Certainly not in the long term, and as we're beginning to see, not really even in the short to medium term, either!
The only reason it keeps happening is that oligarchs have managed to set up the system such that it externalizes their costs, so they personally get more profit even as the total profit is lowered compared to what it could have been.
