Greenland ice sheet melting more rapidly from impact of rainfall

2015-07-17 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed

Environmental News Network: According to a new study published in Nature Geoscience, the Greenland ice sheet has been shown to accelerate in response to surface rainfall and melt associated with late-summer and autumnal cyclonic weather events. Samuel Doyle and an international team of colleagues led from Aberystwyth University's Centre for Glaciology combined records of ice motion, water pressure at the ice sheet bed, and river discharge with surface meteorology across the western margin of the Greenland ice sheet and captured...

Polar bears can't adapt melting Arctic, will waste away

2015-07-17 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

InsideClimate: Polar bears have been one of the species hit hardest by climate change over the last decade, experiencing population declines up to 40 percent in some areas. Even so, scientists have long held out hope the mammals might adapt in some way to their melting Arctic habitat and reboundor at least stabilize in numbersas the world continues to warm. But new research published Thursday in the peer-reviewed journal Science deals a blow to that optimism. Eight U.S.-based scientists tested a leading hypothesis...

Sir Ranulph Fiennes calls urgent action on climate change after witnessing Arctic melting

2015-05-30 22:47:00| Climate Ark Climate Change & Global Warming Newsfeed

Independent: Sir Ranulph Fiennes has added his voice to calls for urgent action to tackle climate change after seeing the effects of warming on the planet first-hand during trips to the Arctic. Sir Ranulph, the first to cross Antarctica on foot as well as to visit both the North and South Poles by surface, said it would be suicide to put commercial interests over global warming. He said he knows from personal experience that the warming climate has significantly changed the landscape of the Arctic, melting...

Glaciers in Antarctic thought stable suddenly melting massive rate

2015-05-21 19:32:00| Climate Ark Climate Change & Global Warming Newsfeed

Independent: A sudden and massive melting of glaciers in a part of the Antarctic that was thought to be relatively stable has been detected by satellites monitoring the polar ice sheet, scientists have said. Many glaciers in the Southern Antarctic Peninsula have become unstable since 2009, releasing vast amounts of ice into the sea equivalent to about 56bn tonnes of meltwater each year, the researchers said. Multiple glaciers along a stretch of coastline 750km long have suddenly and consistently started...
