Important new study shows that current climate models underestimate the human-caused slowing of the #AMOC (Atlantic overturning), because they neglect freshwater influx from Greenland melt and other sources.

Weakening of the Atlantic Meridional Overturning Circulation driven by subarctic freshening since the mid-twentieth century - Nature Geoscience

Fresh meltwater entering the Labrador and Irminger seas has resulted in a slowing of the Atlantic Meridional Overturning Circulation since the 1950s, according to a combination of modelling approaches.

@rahmstorf If I've understood correctly (which is optimistic), Europe and North Africa would become a lot colder, even as the planet as a whole becomes a lot warmer. This would entail the collapse of large-scale ecosystems and the extinction of many species. I'm also guessing a lot of fresh water will become locked up in snow and ice. But, hey, there won't be as many hurricanes in the Atlantic.
