24 percent of West Antarctic ice is now unstable: study

By combining 25 years of European Space Agency satellite altimeter measurements and a model of the regional climate, the UK Centre for Polar Observation and Modelling (CPOM) have tracked changes in snow and ice cover across ...

Video: Visualizing the global thaw

One of the causalities of climate change is the diminishing ice cover, affecting our planet in a number of ways.

Tsunami signals to measure glacier calving in Greenland

In recent years, glaciers near the North and South poles, as well as in mountainous areas, have been shrinking due to the effect of global warming, becoming a significant contributor to the recent sea level rise. Calving ...

Measuring iceberg production with earthquakes

Global warming is significantly reducing the volume of ice sheets—like the one covering Greenland—through melting or by shearing away blocks of ice that tumble into the ocean and become icebergs, a process known as calving.

More than 90% of glacier volume in the Alps could be lost by 2100

New research on how glaciers in the European Alps will fare under a warming climate has come up with concerning results. Under a limited warming scenario, glaciers would lose about two-thirds of their present-day ice volume, ...

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.
