Warming of the subpolar Atlantic triggered by freshwater discharge at the continental boundary
[1] The traditional view is that widespread discharge of freshwater into the North Atlantic leads to a reduction of the Atlantic Meridional Overturning Circulation (AMOC), a concomitant reduction of poleward heat transport and a cooling of the climate of the North Atlantic. Here we report upon coupl...
