Arctic at risk from invasive species
2013-11-25 11:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Ecologist: As oceans continue to warm, the number of ships bearing invasive species will increase, and the number of species that may be able to survive in Svalbard will increase. More shipping is sailing through thawing Arctic waters, but while these northern routes might provide opportunities for tourism, mining and cutting down delivery times, the ships may also carry stowaways on board, introducing invasive species to pristine Arctic waters. These findings were recently published in the journal Diversity...

Twice as Much Methane Escaping Arctic Seafloor
2013-11-24 21:29:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: The Arctic methane time bomb is bigger than scientists once thought and primed to blow, according to a study published today (Nov. 24) in the journal Nature Geoscience. About 17 teragrams of methane, a potent greenhouse gas, escapes each year from a broad, shallow underwater platform called the East Siberian Arctic Shelf, said Natalia Shakova, lead study author and a biogeochemist at the University of Alaska, Fairbanks. A teragram is equal to about 1.1 million tons; the world emits about 500 million...

Arctic storms speed up release of methane plumes
2013-11-24 19:17:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: A stormier Arctic could fast-track the greenhouse gas into the atmosphere, potentially accelerating global warming. "Significant quantities of methane are escaping the East Siberian Shelf as a result of the degradation of submarine permafrost," says Natalia Shakhova of the University of Alaska in Fairbanks. She and her team collected data -- at a great cost -- to show that vast areas are releasing plumes of methane gas, which is escaping into the atmosphere. In August 2010, 11 sailors aboard...

US Arctic strategy consistent with Canada's approach: Defence minister
2013-11-24 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Canadian Press: A new Arctic strategy released by the U.S. is welcome and "entirely consistent" with Canada's approach in the region Defence Minister Rob Nicholson said Saturday. Speaking as part of a panel at the Halifax International Security Forum Nicholson said the strategy outlined Friday by U.S. Defence Secretary Chuck Hagel focuses domestically on the north within a context of international cooperation. "Certainly the Americans have a large stake in this and this (strategy) is appropriate. We view this...

Arctic 30 captain re-evaluates protest methods after Russian jails

Guardian: When armed Russian coast guards descended on to the Arctic Sunrise from helicopters and screamed at everyone to get on the ground, Captain Peter Willcox took it as just another day at work. The 60-year-old American has a long history of entanglements with law enforcement across the world, and has been arrested at various times in Turkey, the Philippines, Peru and Denmark. He was also the captain of the Greenpeace ship the Rainbow Warrior, which was bombed by French special forces in 1985, not...
