The sediment found in an Alaskan cave was likely once part of the Cordilleran Ice Sheet, which melted at the end of the last Ice Age. Most of that ice - along with the sediment contained within it ...

A remarkable discovery buried beneath the Olympic Peninsula’s landscape will be the focus of the next Rosmond Evening Talk ...

Ice loss in Greenland is already large, irreversible, and greatly accelerated after centuries of near stability. Though a tipping point for future ice loss has already been crossed, the pace of this ...

Science New 3-D Study of the Greenland Ice Sheet Shows Glaciers Falling Apart Faster Than Expected Crevasses are widening faster as meltwater drives fissures deeper into the ice and lubricates the ...

An ice sheet is a mass of glacial land ice extending more than 20,000 square miles. Ice sheets once covered much of the Northern Hemisphere during the ice age.

The Greenland and Antarctic ice sheets are on course for rapid retreat, even collapse, leading to multiple feet of sea level rise even if the world pulls off the miraculous and keeps global ...

The wind, having tumbled down 4,000 feet of elevation from the domed summit of the ice sheet hundreds of miles to the west, charged over the surface in wavelike pulses. The GreenDrill site sat on ...

Fine soil particles once encased in ice were discovered in a cave about 20,000 years after the frozen sheet melted. This sediment is significant both for what it tells us about the past and what it ...
