“I expect a semi-dystopian future with substantial pain and suffering for the people of the Global South,” one expert said.

Not really. Economies started to slow down and crash when warming gets over 2°C and CO2 production crashes with it.
Finally some good news on the climate. Our ability to fuck the Earth will mostly go away when our civilization collapses. We might even get a second Genghis Khan cooling when everyone dies.
The problem is that feedback loops start to kick in above 2°C so it doesn’t matter if the economy crashes.
In fact, in some cases that makes things even worse. One example is that without smokestacks and ships pumping out sulfur dioxide the albedo of the atmosphere will rapidly drop, which might cause immediate and rapid warming over a period of only a few years.
We could be pushed past 2.5°C or even 3°C without industrial forces contributing at all.
There is a problem of lag. By the time temperatures are high enough to force the economy to stop, the amount of CO2 will be sufficient to continue pushing the temperature up considerably.
Source? (The past tense make me think you’re quoting a paper)
There isn’t one definitive paper I can give. They’re are of course also papers claiming the opposite.
I’ve seen multiple articles about this. Less yield from staple crops, productivity loss with heatwaves, storm damage. There are a bunch of papers too, usually about a specific region. But roughly above 2°C, the hurt really begins with the cost to the economy exceeding almost every country’s growth. Exact numbers differ per article.
Too bad, I’ll have to hunt around myself. Simulation is always a bit vulnerable to assumptions when human behavior is involved, but it’s definitely worth trying to model things.
If that’s true, the political landscape is going to become starkly different. We expect growth right now; it’s used as the yardstick of economic success. Obviously past civilisations didn’t, and we could go back, even peacefully for all I know, but it would be uncharted territory post-industrialisation.
I kind of suspect climate adaptation produces more CO2 than other forms of activity, because it would be construction heavy. I wonder if that’s factored it. Actually, I wonder what the adaptation assumptions are in general.
