Innovations in Ice Drilling Enable Abrupt Climate Change Discoveries
December 17, 2012
At the WAIS Divide site, an area in the West Antarctic Ice Sheet where the abundant snowfall rarely melts, the ice contains tens of thousands of years of annual information about past climate. Scientists are investigating past greenhouse gas records there and other evidence from the ice that will help to understand why and how abrupt climate changes occur.
