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...
Melt 'causes Antarctic sea ice rise'

BBC: Climate change is expanding Antarctica's sea ice, according to a scientific study in the journal Nature Geoscience. The paradoxical phenomenon is thought to be caused by relatively cold plumes of fresh water derived from melting beneath the Antarctic ice shelves. This melt water has a relatively low density, so it accumulates in the top layer of the ocean. The cool surface waters then re-freeze more easily during Autumn and Winter. This explains the observed peak in sea ice during these...
Antarctic sea ice grows as result of warming

Climate News Network: The Arctic may be shrinking as the world warms but Antarctic sea ice is expanding. Blame global warming for that, too, say Dutch scientists. The paradox is that increasing temperatures have set in motion a chain of events in the southern seas that have the opposite effect. Engineers call this negative feedback. So do Richard Bintanja and colleagues of the Royal Netherlands Meteorological Institute. They report in Nature Geoscience that as the Antarctic ice shelves melt, the resulting cool fresh...
Americans want sea level rise prep, not reaction

Inquirer: Sea level rise is happening. In the last century, it's gone up a foot in Delaware Bay, more along the Atlantic coast of New Jersey. That changes everything, from the height of the twice-daily tides to what happens in storms like Sandy, which swept the coast and left more than $70 billion in property damage. So should we prepare for more, or take our chances and simply react if it happens again? An overwhelming majority of Americans -- 82 percent of those surveyed -- opt for preparation,...
