I do not think a collapse is inevitable, see:

I am just repeating the 'gist' I've gotten from my research on the topic, but the risk of AMOC shutdown has gone from a low probability / high impact prediction by 2100, to 'we think there's a strong chance of hitting a tipping point by 2060'. I wish I could point you to a specific paper, but I'm going entirely off memory, and that is fallible

The % likelyhood by x date predictions have swayed back and forth as we've adjusted our predictions of which emissions path we actually wind up following.

I'd highly recommend the analysis I linked if you did not yet check it, he discusses various papers and differences in definitions.

Last updated in June.

Took a min to read the link, that was a surprisingly good summary.

My whole concern with the AMOC is that given it's a non-linear system, and we've seen evidence of 'fast shutdowns' in the climate record before, I fear we are sleepwalking towards an event that could have catastrophic consequences for the global south, and problems there do not stay there. People flee rather than starve.

I also worry what happens to western liberal democracy under the weight of that influx if we're already seeing populism from today's level of migration.

If your country suddenly has hundreds of thousands (or even millions) of weather migrants from countries with vastly different cultures and values to yours, you'll be wishing that populism was your biggest concern.

		We are actually fortunate. Folks from LATAM seem to have no problem integrating with US society. Europe seems to have a much harder time with their pool of migrants. Probably due to the lack of birthright citizenship

What in that link do you think is saying it is not inevitable?

		Even if you read just the conclusion at the bottom it seems obvious that there is no consensus about a collapse being inevitable: > Overall though, there is some common ground in recent research: evidence for AMOC weakening having begun is growing, albeit is not clear in every AMOC metric; a substantial decline is expected with current emissions, that over centuries could potentially push the AMOC to a slow ‘shutdown’ state; and there remains a real but uncertain chance that this slowdown could pass a tipping point beyond which this shutdown is locked in, even if warming is halted or even declines. Exactly how much and quickly the AMOC is weakening, and the likelihood of it reaching a tipping point, remain much more uncertain, but what we do know is enough to justify concern and action to reduce the risk of AMOC shutdown
