New research shows the ongoing Arctic ice loss can play an active role in altering one of the planet's largest water circulation systems: the Atlantic Meridional Overturning Circulation (AMOC). AMOC has a lower limb of dense, cold water that flows south from the north Atlantic, and an upper limb of warm, salty water that flows north from the south Atlantic as part of the Gulf Stream. AMOC plays a major role in regional and global climate. [Source: Yale University]
