Melt from below helping shrink Antarctic glaciers

LiveScience: The ice that Antarctica is losing as chunks break off the continent's many glaciers may be only the tip of the iceberg. Scientists now find much of the ice Antarctica loses is due to melting from the undersides of ice shelves. During the last decade, the Antarctic ice sheet has been melting an increasing amount each year, mostly in the western portion of the continent. Most of the ice Antarctica loses is replaced by snowfall, but any ice that is not replaced adds to a rise in global sea level. ...

Pollution, Not Rising Temperatures, May Have Melted Alpine Glaciers
2013-09-03 09:03:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: Glaciers in the Alps of Europe pose a scientific mystery. They started melting rapidly back in the 1860s. In a span of about 50 years, some of the biggest glaciers had retreated more than half a mile. But nobody could explain the glacier's rapid decline. Now, a new study from NASA's Jet Propulsion Laboratory uncovers a possible clue to why the glaciers melted before temperatures started rising: Soot from the Industrial Revolution could have heated up the ice. Scientists trying to understand...

Layers of soot from coal burning melted Alpine glaciers even in cooler climate
2013-09-02 23:17:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Sooty air from coal burning triggered the initial melting of the mountain glaciers in the European Alps in the second half of the 19th Century when it caused the snow to turn grey and so reflect less sunlight back into space, scientists said. The soot, known as black carbon, caused the glaciers to absorb more heat than usual, causing the ice to recede year by year even though the regional temperatures were colder than today, the researchers found. Alpine glaciers have receded significantly over...

East Antarctic glaciers could be much more vulnerable to climate change than previously thought.
2013-08-28 21:23:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: The warming, melting and potential contributions to sea level rise from glaciers in Greenland and West Antarctica in the face of climate change has long since been a serious concern. The behavior of the much larger East Antarctic ice sheet has been much more uncertain and until now has been thought to be relatively insensitive to climate change. Now an important paper in Nature from Durham University and the University of Zurich has examined a large number of satellite observations of the East...
