Do you mean this?
A collapse of the Atlantic Meridional Overturning Circulation (AMOC) leads to global cooling through fast feedbacks that selectively amplify the response in the Northern Hemisphere.
So now we have global cooling to look forward to?
I'm not good at explaining this, here's the science on climate change
Climate change and the developments it spurs carry the narrative of the Quaternary, the most recent 2.6 million years of Earth's history. Glaciers advance from the Poles and then retreat, carving and molding the land with each pulse. Sea levels fall and rise with each period of freezing and thawing. Some mammals get massive, grow furry coats, and then disappear. Humans evolve to their modern form, traipse around the globe, and make a mark on just about every Earth system, including the climate.

If there's an AMOC collapse, one of the likely outcomes is literally The Day After Tomorrow. The science in that movie is surprisingly grounded in reality.
Not even remotely accurate. It would cause notable changes and likely widespread famine but not anything as instantly apocalyptic as the film. Temperatures wouldn’t change dramatically aside from Northern Europe. The gulf stream’s effect on temperatures is smaller than people think.
The bigger change globally speaking would be shifting precipitation patterns. This could lead to dramatic aridification of parts of Africa and India, and large increase in precipitation in North America. But it’s not going to trigger some kind of hemispheric ice age as depicted in the film.
Don't worry there's a pill for that, I've seen the adverts.
Yes, Jack Hall will save us!
Goodbye Iceland.
Iceland is not the one made of ice. Confusingly, that’s Greenland. According to this data, Iceland would get colder over the centuries. They won’t disappear.
I should know I'm from there and currently live there. The decline of the gulf stream will heavily affect Iceland. It's basically the only thing keeping this northern rock warm.
In my lifetime the weather here has been getting more and more extreme by each year. (Was trying to find the source to back this up but i can't remember where it is rn, probably here somewhere: https://www.vedur.is/gogn/)
Iceland will be disappear under thick ice
Shit
