Emerging cracks in the Pine Island Glacier

The Copernicus Sentinel-1 and Sentinel-2 satellites have revealed new cracks, or rifts, in the Pine Island Glacier—one of the primary ice arteries in the West Antarctic Ice Sheet. The two large rifts were first spotted ...

Swiss glaciers shrink 10 percent in five years: study

Switzerland's glaciers have lost a tenth of their volume in the past five years alone—a melting rate unmatched during observations stretching back more than a century, a study showed Tuesday.

Aerial photographs shed light on Mont Blanc ice loss

In 1919, the Swiss pilot and photographer Walter Mittelholzer flew over Mont Blanc in a biplane photographing the alpine landscape. Exactly 100 years later, researchers from the University of Dundee in Scotland have recreated ...

Disappearing Peruvian glaciers

It is common knowledge that glaciers are melting in most areas across the globe. The speed at which tropical glaciers in the Peruvian Andes are retreating is particularly alarming, however. In the first detailed investigation ...

Hardy scientists trek to Venezuela's last glacier amid chaos

Blackouts shut off the refrigerators where the scientists keep their lab samples. Gas shortages mean they sometimes have to work from home. They even reuse sheets of paper to record field data because fresh supplies are so ...

Glacier

A glacier is a large mass of ice moving slowly over some land surface or down a valley, formed over long periods from the accumulation of snow in areas where the amount of snow that falls exceeds the amount that melts. The word glacier comes from French via the Vulgar Latin glacia, and ultimately from Latin glacies meaning ice.

Glacier ice is the largest reservoir of fresh water on Earth, and second only to oceans as the largest reservoir of total water. Glaciers cover vast areas of the polar regions and are found in mountain ranges of every continent except Australia, as well as in New Zealand. In the tropics glaciers are restricted to the highest mountains. The processes and landforms caused by glaciers and related to them are referred to as glacial. The process of glacier growth and establishment is called glaciation. Glaciers are sensitive monitors of climate conditions and are crucial to both world water resources and sea level variation.
