Most climate model simulations don't go beyond 2100. But in all high emission projections that were run through 2300, the Atlantic overturning circulation (AMOC) was found to collapse. Of the low emission projections (in line with the Paris Agreement), still a quarter was found to eventually lead to a collapsed #AMOC.
AMOC collapse in climate models is preceded by deep convection (i.e. vertical mixing of water) in the North Atlantic stopping, usually mid-21st century.
