This is the latest update of findings by a research team who have been monitoring methane releases in northern Siberia for the last 20 years. Their recent findings are looking worse than the preliminary data with discoveries of huge eruptions of atmosphere destroying methane gas. This release of methane from thawing of the Arctic tundra has long been anticipated and feared by climate scientists. For more clarification see also "Global Warming Feedback Loop Caused by Methane" from National Geographic and Wikipedia's explanation of greenhouse gases.
Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region.
