Giant plumes of methane bubbling to surface of Arctic Ocean | The Sideshow - Yahoo! via @yahoosg

Methane bubbles trapped in the arctic ice Russian scientists have discovered hundreds of plumes of methane gas, some 1,000 meters in diameter, bubbling to the surface of the Arctic Ocean . Scientists are concerned that as the Arctic Shelf recedes, the unprecedented levels of gas released could greatly accelerate global climate change. Igor Semiletov of the Russian Academy of Sciences tells the UK's Independent that the plumes of methane, a gas 20 times as harmful as carbon dioxide, have shocked scientists who have been studying the region for decades. "Earlier we found torch-like structures like this but they were only tens of meters in diameter," he said. "This is the first time that we've found continuous, powerful and impressive seeping structures, more than 1,000 metres in diameter. It's amazing." Semiletov said that while his research team has discovered more than 100...
