Nations Will Discuss Antarctic Ocean Conservation Proposals in Germany
2013-07-12 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Representatives from 25 countries and the European Union plan to discuss whether to declare a large portion of ocean around Antarctica as a protected area, though the rights to fish in the waters off Antarctica's coast may stall or break the deal. Two proposals are being discussed. One, submitted by the United States and New Zealand, would focus on protecting the Ross Sea, south of New Zealand; the other, submitted by France, Australia and the European Union, would set aside huge areas of the...

Enormous City-sized Iceberg Breaks off Antarctic Glacier
2013-07-10 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: An enormous iceberg with an area about eight times the size of Manhattan has broken off an Antarctic glacier. A huge crack along the surface of Pine Island Glacier (PIG), the longest and fastest shrinking glacier in the Antarctic, finally spread completely across the glacier's surface, creating the 278 square mile (720 sq km) iceberg. Scientists had suspected such a thing would occur since 2011 when they first noticed the crack. Confirmation that the iceberg had broken off the glacier was made...

Huge iceberg calves off Antarctic glacier
2013-07-10 16:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: An iceberg half the size of Greater London has calved off Pine Island glacier in the Antarctic. This week a radar instrument on the German satellite TerraSAR-X captured an image of a crack having grown to extend across the entire ice shelf at the front of the glacier since 2011. Scientists say that the 720-sqkm iceberg calved off in a natural event unrelated to the effects of global warming. Andy Smith of the British Antarctic Survey said: "Although there's nothing to suggest this event is...

Antarctic lake 'might have fish'
2013-07-08 15:29:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: There could be some complex animals living in Lake Vostok, which lies close to 4km below Antarctica's ice sheet. The possibility is raised by scientists who have sifted genetic material in ice drilled from close to Vostok's surface. They found signatures for organisms such as bacteria that are often associated with marine molluscs, crustaceans and even fish. But the team cautions in the PLoS One journal that this material may also represent past contamination. Scientists now recognise...
Warming Ocean Biggest Driver of Antarctic Ice Melt
2013-06-20 19:09:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: Of Earth`s two vast ice sheets, Antarctica is perhaps the more mysterious. From the icy surface to the ocean below, there are several different ways the ice sheet is shrinking. How these processes compare is key to knowing how fast melting ice sheets are raising sea levels worldwide--and a new study may help to shed a bit more light. Ice Sheets and Sea Level Rise There is huge scientific interest in monitoring how the ice sheets are changing because when ice on land melts it drains into the...
