Scripps Institute, Yale University and other researchers removed the bias in current climate models and re-ran AMOC (Atlantic Meridional Overturning Circulation) simulations. The result prompted them to predict a collapse of the circulation at some point in the future, setting off large-scale cooling in the North Atlantic.
The collapse would stop the AMOC, which delivers warm surface water toward Greenland then sinks as it cools and flows back toward the equator closer to the seafloor.
