Reality doesn’t give a shit about your beliefs, as the saying goes.
Personally, I think there's a worryingly high chance that ourselves or our kids will live in a dead, desertified, apocalyptic hellscape of a planet after we hit 5+ degrees of warming, but saying that doesn't mean I _want_ it to happen. In fact, I would prefer it not to!
One of the reasons that I’m slightly less worried about a climate apocalypse is that there isn’t an equivalent group of people that sees the “inevitability” and concludes that it must be a moral good for the planet to warm 5 degrees. I’d argue that multiple degrees of warming is more inevitable than paperclips, but there’s a serious global effort to mitigate and avoid it anyway!
I mean I might think oil prices will go up but still choose not to buy oil stocks for moral reasons.
