AMOC on edge: new studies warn Atlantic current could weaken toward collapse

Two Science Advances studies warn the Atlantic Meridional Overturning Circulation (AMOC) is already weakening across four western Atlantic sites and could slow by more than 50% by 2100, potentially collapsing this century due to anthropogenic climate change. A weakening AMOC would cool parts of the North Atlantic, increase European winter storms, reduce Sahel and South Asian rainfall, and raise sea levels along the U.S. Northeast, underscoring the need for emissions cuts and ongoing monitoring.
