"Stable" Antarctic Permafrost Melting Faster than Expected, Researchers Say
2013-07-24 14:33:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: The stable ice on Antarctic- the coastal permafrost- is melting faster than expected, a new study reported. Researchers said that the melting rate of the coastal Antarctic permafrost is now similar to the melt rate of permafrost at Arctic. The permafrost in Antarctic was considered to be in equilibrium, meaning that it did melt and refreeze, but its mass remained the same. The regions experienced a cooling trend in the past decade and now have stable temperatures. However, researchers have...

Ancient ice melt unearthed in Antarctic mud: 20 meter sea level rise, five million years ago
2013-07-22 03:45:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately 20 metres, scientists report today in the journal Nature Geoscience. The researchers, from Imperial College London, and their academic partners studied mud samples to learn about ancient melting of the East Antarctic ice sheet. They discovered that melting took place repeatedly between five and three million years ago, during a geological period called Pliocene...
Nations fail again to agree protection for Antarctic seas

Reuters: Proposals to create vast marine sanctuaries to protect Antarctic wildlife from fishing and other human activity failed on Tuesday due to opposition from Russia, environmental observers said. The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), a 25-member inter-governmental body, was considering two proposals to designate large tracts of ocean off-limits for almost all activities aside from scientific exploration. However, at a meeting of the organization, Russia,...

Consensus of 25 Nations Necessary to Protect Antarctic Waters
2013-07-15 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Two proposals designed to protect huge swaths of open water off the shores of Antarctica are hinged on the unanimous consensus of a 25-nation committee, which is meeting this week in a special session to vote whether to establish conservation zones in the Ross Sea and waters off East Antarctica. However countries with fishing interests may thwart the international effort to turn the waters into marine protected areas.

Nations to decide on creating vast Antarctic marine reserves
2013-07-15 16:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: An international commission is considering whether to designate the waters around Antarctica special marine reserves, a step campaigners say would safeguard the habitat of whales, seals and penguins and more than double the world's protected sea area. Any change in status requires a unanimous decision by the 25 members of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). Two members, Russia and Ukraine, have raised legal concerns, a German delegate told a media...
