Warming climate changes Greenland's landscape as we watch
2013-09-12 11:11:00| Climate Ark Climate Change & Global Warming Newsfeed
Minnesota Public Radio: A warming climate is reshaping Greenland as scientists watch, says Paul Huttner, chief meteorologist for MPR News. Runoff from melting glaciers threatens to raise the world's sea level. But the retreating ice is also revealing places never seen before, sparking interest among mining and oil and gas companies. "This is one of the interesting opportunities evolving as the climate changes, whether we like it or not," Huttner said. "Mineral companies, oil and gas companies, they are racing to explore...

Newfangled Icepod Tracks Greenlands Melting Ice Sheets
2013-09-07 18:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The LC-130 Hercules flew low over the ice sheet in a tight grid pattern, Teflon-coated landing skis barely 300 meters above the soft upper layer of snow. At the rear of the plane, scientists clustered round a monitor displaying a regular pattern of dark red waves generated by a radar signal. Somewhere in the vast, white emptiness below were two tiny cracks -- barely 4 inches across -- imperceptible to the naked eye from this altitude, especially beneath fresh snow. But the cracks ran across...

Another Grand Canyon Discovered Beneath Greenland's Ice
2013-08-29 22:52:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: A major feature of the Earth has escaped notice - until now. Scientists reported Thursday that they've discovered a vast canyon, twice as long as the Grand Canyon. It carves a deep scar from the center of the world's largest island out to the coast. And, oh one more detail: It's buried beneath as much as 2 miles of ice. Yes, we're talking about icy Greenland. You may not think of it when you fly over, but beneath all that ice is a hidden terrain of bedrock. Jonathan Bamber from the University...

New Clues to Greenland's Hidden Plumbing
2013-08-15 20:47:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: What happens under Greenland's ice sheet, where water, ice and rock meet, is key to predicting how its glaciers will react to global warming. Turns out, beneath the island's mysterious middle, where the ice is thick and the bottom bedrock difficult to reach, meltwater flows through channels and voids that open when flowing ice travels over rough ground, a new study finds. The passageways are spaces between the rock and the overlying ice. The results, based on computer modeling and fieldwork observations...

Warm and buttery: Greenland's ice flow speeding up
2013-07-18 16:53:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Greenland's massive ice sheet is accelerating its slide toward the ocean because bigger surface melts in recent years are softening the interior of the ice like a stick of butter, a new study finds. For more than a decade, scientists have reported rapid melting and shrinking at many of Greenland's outlet glaciers, which snake into the ocean. Studies suggest warmer ocean water and rising atmospheric temperatures contribute to the melting ice. The new study finds the interior ice sheet also speeded...
