Research by Lamont’s Billy D’Andreas revealed that over the last century, glaciers in Greenland have been retreating quickly — at a rate at least twice as fast as any other time in the past 9,500 years.
Evidence buried in Greenland’s bedrock shows that the Greenland Ice Sheet nearly disappeared for an extended time in the last million years or so.
23 million years ago, the Antarctic ice sheet was shrinking quickly. A new study by Lamont scientists sheds light on the cause of that ancient melt.
Much of the modern understanding of climate has been shaped by pioneering studies done at Columbia University’s Lamont-Doherty Earth Observatory.
As global temperatures rise, knowing just how far Greenland’s ice sheet shrank in the past could help scientists predict sea level rise in the future.
