  • Abrupt changes in climate, termed Dansgaard–Oeschger and Heinrich events, have punctuated the last glacial period (∼100–10 kyr ago) but not the Holocene (the past 10 kyr). Here we use an intermediate-complexity climate model to investigate the stability of glacial climate, and we find that only one mode of Atlantic Ocean circulation is stable: a cold mode with deep water formation in the Atlantic Ocean south of Iceland. However, a ‘warm’ circulation mode similar to the present-day Atlantic… CONTINUE READING
