Abrupt climate shifts in Greenland due to displacements of the sea ice edge, Geophys
An atmospheric circulation model is used to show that small reductions in sea ice extent in the North Atlantic are capable of explaining the abrupt changes in temperature, snow accumulation and oxygen isotopes recorded in Green-land during the Dansgaard-Oeschger (D-O) events of the last glacial peri...
