You remind me of Barrett from FF7. They killin' the planet, Cloud! Good memories.

I think it's very far from obvious that children 2-3 generations from now will die horribly due to climate change. It's clear that it's a real phenomenon, but the impact remains to be seen. People have also been predicting doomsday scenarios roughly since people were people, yet the planet finds a way around them and life goes on.

It's not really about being nice. It's more like, if there were evidence that climate change will absolutely lead to large-scale death and destruction, then it wouldn't be necessary to make it a moral imperative to care about it. As it stands, it's very hard to prove that it will. And without proof, the idea that people should be shamed for being skeptical doesn't really add up.
