Climate change not fully to blame for melting sea ice: Study
2014-05-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
CTV: A newly published paper says climate change caused by humans could be responsible for as little as half the wholesale melting of sea ice in the Canadian Arctic and Greenland that has amazed and alarmed scientists. The finding, published in Nature magazine, should caution those attempting to turn global theories into regional predictions, said co-author Mike Wallace of the University of Washington. "Whenever you start to look at local climate trends, you have to look at the internal variability...
Greenland melting due equally to global warming, natural variation
2014-05-08 01:17:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The rapid melting of Greenland glaciers is captured in the documentary "Chasing Ice." The retreat of the ice edge from one year to the next sends more water into the sea. Now University of Washington atmospheric scientists have estimated that up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable...

Rapid Arctic melting only partly our fault
2014-05-07 19:32:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: The rapid warming and melting of the Arctic is only half our fault. While our greenhouse gas emissions are clearly a factor, the record melts of the past few decades are partly the result of huge waves of warm air emanating from the Pacific Ocean. The same region of the Pacific seems to be behind both the Arctic warming and the global warming "hiatus" of the last decade. That means we could be in for something unexpected: when global warming speeds up again, the melting of the Arctic might slow...

Melting East Antarctica ice could mean thousands of years of unstoppable sea level rises
2014-05-07 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Science 2.0: The melting of a rather small ice volume on East Antarctica's shore could trigger a persistent ice discharge into the ocean, resulting in unstoppable sea-level rise for thousands of years to come, according to computer simulations of the Antarctic ice flow by scientists at the Potsdam Institute for Climate Impact Research (PIK). They detail their estimates in Nature Climate Change. "East Antarctica's Wilkes Basin is like a bottle on a slant," says lead-author Matthias Mengel, "once uncorked, it...
Melting Antarctic Ice May Trigger Unstoppable Sea-Level Rise
2014-05-05 21:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Yet another melting ice formation in Antarctica may dump so much water into the ocean that it could trigger an unstoppable rise in sea level for thousands of years to come, a new study published in Nature Climate Change revealed. The current region threatening to raise our seas is the Wilkes Basin, the largest region of marine ice on rocky ground in East Antarctica. Currently, only a rim of ice at the coast holds the ice behind in place. "East Antarctica's Wilkes Basin is like a bottle on a...
