Antarctic thawing season keeps getting longer

LiveScience: More ice is melting for a longer period of time each year on the Antarctic Peninsula, new research shows. The area is warming more quickly than almost any other spot on Earth. Temperatures on this mountainous strip of land have risen by 5.4 degrees Fahrenheit (3 degrees Celsius) since the 1950s, according to a news release from the British Antarctic Survey, whose scientists were involved in the research. The study, published today (March 27) in the Journal of Geophysical Research: Earth Surface,...

Melt 'causes Antarctic sea ice rise'
2013-04-01 12:12:00| Climate Ark Climate Change & Global Warming Newsfeed
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...
Summer melt season getting longer on Antarctic Peninsula
2013-03-27 21:38:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: New research from the Antarctic Peninsula shows that the summer melt season has been getting longer over the last 60 years. Increased summer melting has been linked to the rapid break-up of ice shelves in the area and rising sea level. The Antarctic Peninsula -- a mountainous region extending northwards towards South America -- is warming much faster than the rest of Antarctica. Temperatures have risen by up to 3 oC since the 1950s -- three times more than the global average. This is a result...

The Antarctic is left defenceless to tourism
2013-03-17 01:29:00| Climate Ark Climate Change & Global Warming Newsfeed
Independent: Across most of Earth, a tourist attraction that sees 35,000 visitors a year can safely be labelled sleepy. But when it's Antarctica, every footstep matters. Tourism is rebounding here five years after the financial crisis and is now growing fast, with the number of cruise ship passengers visiting doubling in a year. Although the downturn triggered by the economic collapse created an opportunity for the 50 countries that share responsibility through the Antarctic Treaty to set rules to manage tourism,...
