A major chunk of Greenland’s ice sheet melted 7,000 years ago – and scientists say it didn’t take much

A team drilling in Greenland found that a major high point of the ice sheet vanished entirely about 7,000 years ago, during conditions not dramatically warmer than today, and scientists are worried

Researchers have uncovered evidence that a major section of Greenland’s ice sheet disappeared during a relatively mild warm period thousands of years ago

Scientists have known for a while that Greenland’s ice sheet is more vulnerable than it looks, and a drilling project called GreenDrill has just turned up evidence that makes it look way worse than they were expecting.

A fresh study by University at Buffalo has revealed that the Prudhoe Dome – a major elevated section of the ice sheet in northwest Greenland – completely vanished around 7,000 years ago and stayed gone for what may have been thousands of years.

What’s more, it’s been said to have happened during the Holocene, which is generally considered a period of relatively stable climate and is the same geological epoch we’re living in now.
