Climate change severe threat to marine turtles
2013-02-19 08:25:00| Climate Ark Climate Change & Global Warming Newsfeed
Times of India: Scientists have sounded the alarm over the mounting threat to marine turtle populations worldwide from climate change and coastal development. The scientists have made a strong pitch for protecting key nesting grounds, and areas that may be suitable for the purpose in the future, to ensure that the marine reptiles have a better chance of withstanding climate change. Turtles play a significant role in seed dispersal and ecology. They act as scavengers of the marine ecosystem, cleaning up a lot...

Associated Press: The Marshall Islands and other low-lying island nations appealed to the U.N. Security Council on Friday to recognize climate change as an international security threat that jeopardizes their very survival. Tony deBrum, a minister and assistant to the Marshall Islands president, said the island nations are facing opposition from Security Council permanent members Russia and China and a group of more than 130 mainly developing nations, which argue that the U.N.'s most powerful body is the wrong...

Climate Change a Bigger Extinction Threat than Asteroids
2013-02-16 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: As teaching moments go, it doesn't get much better than this. NASA scientists have known for nearly a year that a small asteroid called 2012 DA14, about 150 ft. across, would whiz past Earth at the nail-biting distance of 17,000 miles or so -- significantly closer than the 22,500-mile altitude occupied by geosynchronous satellites. It happened right on schedule on Friday morning, with no consequences at all for Earth. But nobody had a clue that a space rock about a third as large would scream...

Arctic sunshine cranks up threat from greenhouse gases
2013-02-12 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: IT'S a solar double whammy. Not only does sunlight melt Arctic ice, but it also speeds up the conversion of frozen organic matter into carbon dioxide. The amount of carbon in dead vegetation preserved in the far northern permafrost is estimated to be twice what the atmosphere holds as CO2. Global warming could allow this plant matter to decompose, releasing either CO2 or methane - both greenhouse gases. The extent of the risk remains uncertain because the release mechanisms are not clear. Rose...
