Glacier - Wikipedia, the free encyclopedia
Narrow, fast-moving sections of an ice sheet are called ice streams . ... Portions of an ice sheet or cap that extend into water are called ice shelves ; they tend to be thin with limited slopes and reduced velocities .
Global Glacier Changes: facts and figures
If the trend continues and governments fail to agree on deep and decisive emission reductions at the crucial UN climate convention meeting in Copenhagen in 2009, it is possible that glaciers may completely disappear from many mountain ranges in the 21st century. ... There is mounting evidence that climate change is triggering a shrinking and thinning of many glaciers world-wide which may eventually put at risk water supplies for hundreds of millions -- if not billions -- of people.
These Stunning Photos of Greenland's "Dark Snow" Should Worry You | Mother Jones
The most likely is that some combination of increasingly infrequent summer snowstorms, wind-blown dust, microbial activity, and forest fire soot led to this year's exceptionally dark ice. ... Crevasses criss-cross the Greenland ice sheet, allowing melt water to descend deep beneath the ice.
