The Scientific Advances’ study’s conclusion is predicated on a single climate model, the Community Earth System Model (CESM), projecting far into the future and it’s also predicated on an amount of ice melt that has not happened in our lifetimes. Even then, the CESM had to have its pump primed with unrealistic meltwater data in order for the researchers to come to the conclusion they got. What they did was to run the model, then add modeled freshwater very gradually to the modeled North Atlantic, presumably simulating a melting of the Greenland ice which might shut down the AMOC.
There’s only one problem; the amount of freshwater from melting that they injected into the model is about five times the actual amount of ice available in Greenland to melt."
So it's very much a fake news scenario.
