Scientists find Antarctic ice is melting faster
2013-04-15 08:44:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The summer ice melt in parts of Antarctica is at its highest level in 1,000 years, Australian and British researchers reported on Monday, adding new evidence of the impact of global warming on sensitive Antarctic glaciers and ice shelves. Researchers from the Australian National University and the British Antarctic Survey found data taken from an ice core also shows the summer ice melt has been 10 times more intense over the past 50 years compared with 600 years ago. "It's definitely evidence...

Antarctic team digs deep to predict climate future as frozen continent becomes research hub
2013-04-08 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: Nancy Bertler and her team took a freezer to the coldest place on Earth, endured weeks of primitive living and risked spending the winter in Antarctic darkness, to go get ice -- ice that records our climate's past and could point to its future. They drilled out hundreds of ice cores, each slightly longer and wider than a baseball bat, from the half-mile-thick ice covering Antarctica's Roosevelt Island. The cores, which may total 150,000 years of snowfall, almost didn't survive the boat ride to...

Antarctic Peninsula melting season is getting longer
2013-04-04 10:55:00| Climate Ark Climate Change & Global Warming Newsfeed
Planet Earth: The summer melting season in the Antarctic Peninsula has lengthened over the last 60 years, new research shows. This is contributing to sea-level rise, and may be linked to the rapid break-up of ice shelves in the area. The Antarctic Peninsula, a mountainous finger of land pointing northwards towards South America, is warming much faster than the rest of Antarctica. Temperatures have risen by almost 3°C since the 1950s -- three times faster than the global average. Scientists think this...

Antarctic ice grows as climate warms
2013-04-03 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: Call it a tale of two poles. While sea ice in the Arctic is vanishing fast, the extent of Antarctic ice has increased. Good explanations for the growth of ice in the Southern Ocean have been hard to find, but now the problem may have been cracked. Counter-intuitively, it seems global warming may be cooling southern surface waters. Nobody predicted that the fate of ice at each pole would take such different paths in just 30 years, with Arctic sea ice dropping more than 15 per cent, even as Antarctic...

New Theory for Why Antarctic Sea Ice Is Growing
2013-04-01 18:38:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: It's a global warming paradox. As air and sea temperatures rise, Arctic sea ice is rapidly and uniformly dwindling. In 2012, Arctic sea ice declined so much that the loss "utterly" obliterated the previous record, set in 2007, according to the U.S. National Snow and Ice Data Center. As of 2012, the area of Arctic sea ice around the North Pole had shrunk to 1.58 million square miles (4.1 million square kilometers)-the smallest measurement since 1979, when satellite observations began. But...
