The last 40 ky, have been characterized by abrupt and high amplitude temperature changes (8 to 15 °C in less than 300 years) in Greenland and in the North Atlantic region, associated with drastic ocean and atmospheric circulation changes. The mechanisms behind these abrupt climate changes are still...
