Global warming melts edge of Greenland icesheet

Agence France-Presse: The last edge of the Greenland ice sheet that had resisted global warming has now become unstable, adding billions of tonnes of meltwater to rising seas, scientists say. In a study published in the journal Nature Climate Change, they say a surge in temperature from 2003 has eased the brakes on a long "river" of ice that flows to the coast in northeastern Greenland. Known as an ice stream, the "river" takes ice from a vast basin and slowly shifts it to the sea - in the same way the Amazon River...

New Greenland Ice Melt Fuels Sea Level Rise Concerns
2014-03-17 00:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Stability in the rapidly changing Arctic is a rarity. Yet for years researchers believed the glaciers in the frigid northeast section of Greenland, which connect to the interior of the country's massive ice sheet, were resilient to the effects of climate change that have affected so much of the Arctic. But new data published Sunday in Nature Climate Change reveals that over the past decade, the region has started rapidly losing ice due to a rise in air and ocean temperatures caused in part by...
Greenland Ice Melt 'Accelerating' Climate Change Awakens 'Sleeping Giant'

International Business Times: Scientists have known for decades that Greenlands ice sheet is melting, but they may have underestimated just how much water the second-largest ice sheet on the planet is shedding. New research indicates that a key section of northeast Greenland thought to be stable is actually dumping billions of tons of water into the ocean annually after a barrier of ice debris that had blocked its flow finally gave way. "We're seeing an acceleration of ice loss," Michael Bevis, professor of earth sciences...

Study Says Climate Change Accelerating Greenland Ice Loss
2014-03-16 20:40:00| Climate Ark Climate Change & Global Warming Newsfeed
Time: Greenland`s ice sheet is rapidly melting in areas previously believed to be stable, leading to accelerated rises in global sea levels, according to a study published Sunday. While scientists have been aware that climate change has caused Greenland`s ice sheet to thin for decades, melting in the sheet`s northeast region has been discovered for the first time, USA Today reports. Ice loss in the northeast region of Greenland has nearly tripled since 2003, with the ice sheet retreating 12.4 miles...
Fears of faster rising global sea levels as 'stable' Greenland ice sheet starts to melt
2014-03-16 19:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Global sea levels may rise faster than anticipated due to a rapid melting of the north-east corner of the Greenland ice sheet, according to scientists. This was widely considered to be cold and stable. Satellite measurements have shown that this part of Greenland, which covers 16 per cent of the ice sheet, has now begun to melt after many years of stability the reason why this area was left out of computer models predicting future global sea-level rise. Regional warming in north-east Greenland...
