Rapid climate variability during warm and cold periods in polar regions and Europe

Typical rapid climate events punctuating the last glacial period in Greenland, Europe and Antarctica are compared to two rapid events occurring under warmer conditions: ( i ) Dansgaard-Oeschger event 25, the first abrupt warming occurring during last glacial inception; ( ii ) 8.2 ka BP event, the on...

Description
Summary:Typical rapid climate events punctuating the last glacial period in Greenland, Europe and Antarctica are compared to two rapid events occurring under warmer conditions: ( i ) Dansgaard-Oeschger event 25, the first abrupt warming occurring during last glacial inception; ( ii ) 8.2 ka BP event, the only rapid cooling recorded during the Holocene in Greenland ice cores and in Ammersee, Germany. The rate of warming during previous warmer interglacial periods is estimated from polar ice cores to 1.5 °C per millennium, without abrupt changes. Climate change expected for the 21st century should however be at least 10 times faster. Udgivelsesdato: 23 May
