Natural variability of the Arctic Ocean sea ice during the present interglacial.

Data from cores collected in the surrounding subarctic seas of the North Atlantic, in particular, the Greenland, Norwegian, and Barents seas, as well as the Baffin Bay also show relatively large amplitude variations in their winter and spring sea-ice cover but mostly illustrate an increasing trend from the thermal optimum of the early–middle Holocene characterized by low sea-ice cover, toward the neoglacial high sea-ice cover of the very late Holocene ( 16 , 22 – 28 ).
