Abrupt Climate Change In The Arctic (And Beyond) An Update

AGU Fall Meeting 2013: Our understanding of future Arctic change is informed by the history of past changes, which often have been both large and abrupt. The well-known ice-age events such as the Younger Dryas show how sea-ice changes can amplify forcing to produce very large responses, with wintertime sea ice especially important. These changes…
