7,000 massive methane gas bubbles under the Russian permafrost could explode anytime

Thin Progress has a report on Siberia's melting permafrost - 7,000 massive methane gas bubbles under the Russian permafrost could explode anytime.

Russian scientists have recently discovered some 7,000 underground methane bubbles in Siberia that could explode anytime. ‘Their appearance at such high latitudes is most likely linked to thawing permafrost,” explained a Russian Academy of Science spokesperson, “which is in turn linked to overall rise of temperature on the north of Eurasia during last several decades.”

This discovery is especially worrisome for three reasons. First, methane traps 86 times as much heat as CO2 over a 20-year period. Thawing permafrost creates both CO2 and methane (CH4), but most models of thawing permafrost assume only CO2 is created. If, as it appears, a lot of methane is being generated, then we’ll see even more extra warming than scientists have projected. Second, a recent study found global warming will defrost much more permafrost than we thought. Third, the permafrost has already been warming at an alarming rate. In general, the Arctic warms twice as fast as the planet as a whole.
