Russian Scientist Discovers Giant Arctic Methane Plumes

thomst writes "Russian scientist Igor Semiletov of the International Arctic Research Centre at the University of Alaska Fairbanks revealed in an interview with The Independent that his team discovered 'powerful and impressive seeping structures (of Methane gas) more than 1,000 metres in diameter' during their survey of the Arctic Ocean earlier this year. 'I was most impressed by the sheer scale and the high density of the plumes. Over a relatively small area we found more than 100, but over a wider area there should be thousands of them,' Semiletov told The Independent's Steve Connor. This finding is important because methane is estimated to be 20 times as potent as carbon dioxide as a greenhouse gas, and it could indicate that global warming is about to accelerate dramatically."
