During the last Ice Age (about 110 000 to 10 000 years ago), a number of abrupt climate warming events increased temperatures up to 16.5°C over the Greenland Ice Sheet over just a few decades. New analysis of ice and sediment cores shows that such events were tightly linked to rapid and widespread sea-ice decline in the Greenland, Barents and Norwegian Seas over a span of less than 250 years. The rate of warming during those events is analogous to current atmospheric warming and sea-ice retreat in the Arctic, which may foreshadow similar changes in the region and significantly impact lower latitude climate as well.
