Cold blob

Common card · No. 276435

The cold blob in the North Atlantic (also called the North Atlantic warming hole) is a cold temperature anomaly of the surface waters at a region in the North Atlantic Ocean south of Greenland, affecting the Atlantic meridional overturning circulation (AMOC) which is part of the thermohaline circulation, possibly related to global warming-induced melting of the Greenland ice sheet. It is the largest structurally anomalous cold oceanic region on Earth.
