Hubbard Glacier defies climate change, continues advancing
2015-06-13 21:54:00| Climate Ark Climate Change & Global Warming Newsfeed
CBC: A Yukon glacier is slowly advancing towards an Alaskan river, setting the stage for an awesome collision of natural forces. If the glacier that originates near Mount Logan in the Yukon continues advancing at its current rate, it could block access to a fiord in Alaska and "strongly impact" the nearby ecosystem. New research from the University of Kansas suggests the Hubbard Glacier could permanently dam the entrance to Russell Fiord, on the Gulf of Alaska, within 25 years. The timeline is the...

Massive Glacier Melt Pouring into Gulf of Alaska
2015-03-21 18:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: The collective freshwater discharge of this region is more than four times greater than the mighty Yukon River of Alaska and Canada, and half again as much as the Mississippi River. While scientists had indeed noticed this runoff, until now they had no idea the magnitude of its impact. If all this mountain rain, snow and glacial ice melt empties into the Gulf of Alaska, it would create the sixth largest coastal river in the world if it emerged as a single stream, researchers say. "Freshwater...

Study raises concerns over big, rapidly thinning Antarctic glacier
2015-03-18 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
CNN: Scientists have raised concerns about a large, rapidly thinning glacier in Antarctica, warning it could contribute significantly to rising sea levels. They say they've discovered two openings that could channel warm seawater to the base of the huge Totten Glacier and bring the threat of potentially disastrous melting. The glacier is bigger and thinning faster than all the others in East Antarctica. It contains enough ice to raise the global sea level by at least 11 feet (3.4 meters), according...

Evidence glacier ice: Until banned, leaded gasoline dominated humanmade lead emissions
2015-03-08 17:47:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Leaded gasoline was a larger emission source of the toxic heavy metal lead than mining in South America -- even though the extraction of metals from the region's mines historically released huge quantities of lead into the environment. Researchers from the Paul Scherrer Institute PSI and the University of Bern have discovered evidence of the dominance of leaded gasoline based on measurements in an ice core from a Bolivian glacier. The scientists found that lead from road traffic in the neighbouring...
