Ice researchers capture catastrophic Greenland melt

2015-01-13 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

LA Times: Over a few summer days in 2012, nearly all of the Greenland ice sheet surface thawed right under the feet of a UCLA-led team of scientists. What was not absorbed into snow quickly gathered and flowed across the 20,000-square-mile sheet, coalescing into roaring turquoise rivers. And then most of it disappeared. Where all that water went may seem an easy guess. But that`s just the problem with Greenland ice science -- some of the guesses have been wrong, according to a study published online...

Greenland may lose ice more rapidly than previously thought

2014-12-20 14:03:00| Climate Ark Climate Change & Global Warming Newsfeed

Environmental News Network: The Greenland Ice Sheet is the second-largest body of ice on Earth. It covers an area about five times the size of New York State and Kansas combined, and if it melts completely, oceans could rise by 20 feet. Coastal communities from Florida to Bangladesh would suffer extensive damage. Now, a new study is revealing just how little we understand this northern behemoth. Led by geophysicist Beata Csatho, UB associate professor of geology, the research provides what the authors think is the first...

Professor documents climate-change effects in Greenland

2014-10-13 02:45:00| Climate Ark Climate Change & Global Warming Newsfeed

Stevens Point Journal: A professor from the University of Wisconsin-Stevens Point traveled with one of his former students to Greenland over the summer to study peregrine falcons and document changes in their lives caused by climate change. Biology professor Bob Rosenfield traveled with alumna Maddie Hardin to Greenland for two weeks to document the ages of nestling peregrines, based on the development of their feathers, and compared the data to information collected in previous years. Rosenfield said he believes the...

'Plumbing System' Slows Greenland Ice Sheet

2014-10-07 00:08:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World: The subglacial "plumbing system" beneath Greenland is slowing the ice sheet's movement toward the sea as the summer progresses, according to new research. "Everyone wants to know what's happening under Greenland as it experiences more and more melt," study co-author Ginny Catania, a research scientist at the University of Texas at Austin's Institute for Geophysics, said in a statement. "This subglacial plumbing may or may not be critical for sea level rise in the next 100 years, but we don't really...

Soot from Canadian wildfires may have increased Greenland ice melt

2014-10-04 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Radio Canada International: Danish-born glaciologist Jason Box who has studied glaciers for two-decades is in the second year of a study called the Dark Snow Project. He is with the Geological Survey of Greenland and Denmark. They found that soot is covering immense areas of the ice-sheet, darkening and increasing its heat absorption, causing melting to increase. The soot may be from a variety of sources including burning of coal, diesel, dung and wood. Its also thought that greatly increased soot this year is due to...
