💨 Abstract

The North Atlantic has a cooling "blob" south-east of Greenland, which scientists now attribute to a weakening of the Atlantic Meridional Overturning Circulation (AMOC). This oceanic conveyor belt transfers heat around the planet, and its slowdown could lead to significant climate changes, including colder winters in Europe and altered rainfall patterns in Africa and Asia. The weakening is likely due to cold freshwater from melting Greenland ice sheets diluting the warm, salty waters that drive the AMOC.
