But this is exactly the same situation as with the nukes:

There's no way any of us can change the situation individually. We're past the event horizon; nuclear war/catastrophic climate change is a certainty, and we're all going to die. Some brave individuals are protesting against it, and some people are preparing for it. But for most of us, it's a done deal.

I have a theory that it actually allows people to stop worrying about the future, and therefore we don't have to make long-term decisions. It's actually comforting in a "what's the point of saving money, we're all going to die in a nuclear holocaust/climate heatwave anyway. Might as well spend it down the pub now..." way.
