Abstract
Over the past 30 years, ice cores from Greenland, and subsequently from Antarctica, have progressively revealed a fascinating and unexpected picture of inter-hemispheric climate behaviour during the last glacial period, approximately 110,000 to 12,000 years ago. In the north, the glacial cold was punctuated by a series of abrupt warming events, each followed by cooling over several centuries before jumping back to cold, glacial conditions. These Dansgaard–Oeschger (DO) events, as they became known, have counterparts in Antarctic records, although with a different character: the Antarctic events show steady warming trends during Greenland's cold phases that peak and reverse to cooling trends when Greenland warms (Fig. 1).
