Caption: The termination of the Younger Dryas cold event some 11.6k years ago was an abrupt climatic shift. In this record, from Central Greenland, it is manifested as a warming of around 15 °C, accompanied by a doubling in annual precipitation volume, occurring in less than a decade. Shown here are accumulation and oxygen isotope (shown as temperature) records from the GISP2 ice core for the period between 18 and 10 kyr B.P.
