Global Warming Bubbles up from the Deep

European scientists have discovered more than 250 plumes of methane (CH4) gas bubbles rising from the seabed of the West Spitsbergen continental margin in the Arctic, at a depth of 150 to 400 meters. The warming of Arctic currents by 1° over the last 30 years has triggered the release of methane, a potent [...]
