New Theory for Why Antarctic Sea Ice Is Growing

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...
Loss Of Arctic Ice May Be Cause Of This Chilly Spring

RedOrbit: Have you been experiencing the coldest spring weather in recent memory? Its probably because of global warming. According to climate scientists, warmer than average temperatures have thrown a monkey wrench into global weather patterns by melting Arctic sea ice at record rates during the summer months. "Ironically ... as the ice pack retreats and the Arctic heats up, there`s a counteracting tendency in middle latitudes for colder winters, as well as hotter summers," said Stephen Vavrus, senior...
Arctic ice loss drives extreme weather patterns

LA Times: Anyone forced to shovel their car out of a snowbank this winter might wonder just how it is a blizzard can occur in a warming climate. The answer, climate scientists say, may have to do with record sea ice losses in the Arctic. At a Tuesday news conference, several researchers said that warming conditions in the Arctic may be weakening jet stream currents and causing extreme weather systems to linger in northern mid-latitudes. "Ironically ... as the ice pack retreats and the Arctic heats...
