It’s not unusual for ice shelves to calve, many in the climate community fear that the breaking of Larsen C may be a signal of other events to come.
Research by geophysicist Christine McCarthy reveals how glaciers move, what makes them speed up, and how they are contributing to sea level rise as the climate warms.
During the last glacial period, there were lakes under Antarctica’s ice sheet, which may have accelerated the retreat of glaciers in the past.
The melting of glaciers will affect drinking water supplies, water needed to grow food and supply energy, as well as global sea levels.
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.
