Arctic Seabed Leaking Methane Fast

A dramatic increase in methane gas is seeping from the Arctic seabed off Siberia. The BBC reports the evidence from measurements of carbon fluxes around the north of Russia.

Methane is 20 times more potent a greenhouse gas than CO2.

Worst of all, the latest research by Igor Semiletov (University of Alaska Fairbanks and head of the International Siberian Shelf Study) finds the shallow arctic shelves are shooting methane to the surface and the atmosphere without first getting sequestered in the ocean as dissolved CO2—as happens in deeper ocean waters.

Siberia’s shallow seabed contains tons of frozen methane hydrates. But these waters are warming and the frozen methane is thawing. Last decade’s highest-ever recorded temperature rise began to thaw some of the organic material frozen in underwater sediments, releasing methane into the sea, from there into air.

Higher concentrations of atmospheric methane are a global warming trigger, which in turn melts more permafrost (topside and underwater), creating a nasty, brutish, and potentially short positive feedback loop.

(I’ve blogged about the methane problem a bunch of times and wrote about it in depth in The Thirteenth Tipping Point, including the worst-case scenario of a tipping point being passed and suddenly dumping billions of tons of methane. We know this happened once before, resulting in the worst mass extinction in Earth’s history.)

Combine this study with the National Snow and Ice Data Center report yesterday that December 2009 saw average air temperatures over the Arctic Ocean way higher than normal. Grim.
 

REAL QUICK, REAL URGENT

Minority rule, corruption, disinformation, attacks on those who dare tell the truth: There is a direct line from what's happening in Russia and Ukraine to what's happening here at home. And that's what MoJo's Monika Bauerlein writes about in "Their Fight Is Our Fight" to unpack the information war we find ourselves in and share a few examples to show why the power of independent, reader-supported journalism is such a threat to authoritarians.

Corrupt leaders the world over can (and will) try to shut down the truth, but when the truth has millions of people on its side, you can't keep it down for good. And there's no more powerful or urgent argument for your support of Mother Jones' journalism right now than that. We need to raise about $450,000 to hit our online fundraising budget in these next few months, so please read more from Monika and pitch in if you can.
