Yeaaaaaah booiiii. Here come those feedback loops.
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.
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.
Don’t worry there’s a pill for that, I’ve seen the adverts.
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/)
“While we can definitively say this weakening is happening, we are unable to say to what extent it is related to climate change or whether it is a natural variation,” Piecuch said. “We can see similar weakening indicated in climate models, but for this paper we were not able to put together the observational evidence that would really allow us to pinpoint the cause of the observed decline.”
What observational evidence would prove it either way?
The scope of the study wasn’t wide enough to get definitive evidence that it was man-made climate change based, or simply natural periodicity of climate zones. The Earth has a shit load of climate data over thousands of years to sift through, and that costs money which may be outside of the budget of the study.
Shit
