Doing all those things is possible and there are clear plans to do them, at significant economical costs but nothing that our economies can't handle. This is the technological solution: transition out of oil and carbon in general! We already have I'd say 90% of the technological capability to achieve it and sufficient economic resources (in fact it's happening even without subsidies in many places).

Europe is already on IPCC 2C targets, and it's clearly not starving, its economy is fine. What they need to do is show the rest of the world how we're toast without action.

Just look at the 3 or 4C targets -- that themselves largely predict quick oil phase out! Civilization runs real risk of collapse before the end of the century in those targets, and 3 decades from now it'll already start looking bleak. Imagine if we do nothing.

I guess the most dark humor thing is (most) people imagining their kids living in happy wonderlands, making retirement plans, etc. while the world is literally going to hell.

It really feels like a failure of science, technology and engineering community. We're failing at communicating. Because I owe to and admire so much of our scientific history and people, I'll gladly campaign for climate action to my last day (or at least until we're at a somewhat sane track).
