Ocean and atmosphere equally responsible for Atlantic ‘cold blob,’ scientists find

A patch of the Atlantic Ocean just south of Greenland is cooling while much of the world warms. The origin of this “cold blob” has been linked to weakening ocean currents that help regulate global climate—called the Atlantic Meridional Overturning Circulation (AMOC). A team of scientists led by Penn State has found a weakening AMOC impacts not just the ocean but also the atmosphere, and that these two factors may contribute equally to the cold anomaly.
