The three glaciers that Hamilton and Stearns measured account for about a fifth of the discharge from the entire Greenland ice sheet.

Straneo's research is looking at what scientists call the "dynamic effects" of the Greenland ice sheet.

Previous studies have found temperatures below the ice sheet, caused by the warmth of the planet below, that could melt water.

The Greenland ice sheet is not merely being melted from above by warmer air temperatures.

It would take the melting of an ice sheet to do that.

Both studies suggest the shrinking ice sheet now contributes about 0. 02 inch (0. 5 millimeter) a year to global sea level rise.

The Greenland ice sheet is melting three times faster today than it was five years ago, according to a new study.

Arctic sea ice, Greenland's ice sheet, and glaciers in the Alps and the Antarctic Peninsula are all melting faster.

A research team from the University of Colorado used satellite data to estimate that the ice sheet will lose up to 48 cubic miles by 2050.

Konrad Steffen of the University of Colorado, Boulder, leads one study of the Greenland ice sheet.

The melting of Greenland's ice sheet is accelerating, threatening an increasing rise in sea levels.

It is not simply that the ice sheet is melting steadily as global temperatures rise.

Several rivers of the West Antarctica ice sheet flow into the ice shelf.

Despite the vulnerability of the country's ice sheet to global warming, a recent Greenpeace meeting in Nuuk drew a paltry 45 people.

In addition, there was extensive dynamic thinning on many margins of the ice sheet.

The three glaciers they studied had abruptly increased the speed by which they were transmitting ice from the ice sheet into the ocean.

Their seaward edges are speeding up, and the ice sheet behind them is thinning .

If it and the West Antarctic Ice Sheet melt, sea levels will rise five to 10 meters, displacing half a billion inhabitants.

Knowing what the ice sheet looked like back then let scientists pin down variations in modern models of Earth climate.

A fresh coat of summer snow would have protected the ice sheet, but little snow fell.
