Description
Recent increase of surface melt and outlet glacier discharge from Greenland and surrounding
glaciers and ice caps is changing the freshwater budget of the Arctic and sub-polar North Atlantic Oceans. Impact on the convection, with potential feedback on the strength of the Atlantic meridional overturning circulation (AMOC), which is showing signs of weakening ([1], [2]) is addressed. We compare two sets of five-member ensembles of historical runs from 1920 to 2014 with the coupled climate model IPSL-CM6-LR. One of the ensembles is forced with a realistic set of observational melting trends in order to account for its increase in the 1920s and the 1990s.
