I can only hope they make that. Its honestly not that hard. I’ve probably done a 20-30% reduction in meat consumption over the last year or so (and I intend to keep going), and for the most part its just made the groceries cheaper and made me eat more fiber. That gives them multiple decades to make those changes too, and while obviously that’ll take way more work to do that on a country-wide scale, they also have a full decade to do it.

I hope that goes well for them.

You misunderstand. I was saying that the assumption that the rich folks behind climate change are acting out of ignorance is extraordinarily optimistic. I hope that I’m wrong, but I see no reason to believe that any cost estimate would get the main polluters (all billionaires included) on board with fighting climate change. Corporations and rich private citizens won’t save us, and if they do, I will happily eat my words.

Its going to be collective action and government intervention.

I love your optimism.

No, yes, and yes

This is the take.

As much funds as we can mobilize. The possible futures are all bad, unless we make huge breakthroughs in pretty much all relevant technologies, somewhere between hundreds of millions and billions of people will die. This article is slightly misleading, as it posits cost entirely in terms of money. But the big cost of the changing climate is in lives. We will not be able to solve climate change before it gets much, much worse, so there is no theoretical amount money that would be “enough.” Thus, as much as possible for the least bad possible future.
