In a new scientific research paper, scientists present palaeo-oceanographic evidence that deep convection of surface waters in the North Atlantic - the engine that keeps the Atlantic meridional overturning circulation (AMOC) in constant motion - began to decline as early as around 1850, probably owing to increased freshwater influx from Arctic ice that had melted at the end of a relatively cold period called the Little Ice Age. This could have caused a weakening in the ocean circulation. [Source: Nature]
