'According to the seesaw model, a transition from weak to strong AMOC would cause an abrupt warming across the North Atlantic region (a D-O warming event) while temperatures across Antarctica would (in general) shift from warming to cooling. In other words, the thermal bipolar seesaw model states that there is an inverse relationship between temperatures in Greenland and the rate of change of Antarctic temperature'
‘The glaciers of Greenland hit a low back in the early 1930s that rivals current reports of glacial melting, an indication the Arctic pack ice might have been rather sparse in the summers back then as well’
