Gargantuan Siberian Methane Bubbles Escaping Into Atmosphere

Huge frozen methane deposits exist under Arctic lakes and the oceans, the remains of plants and animals that settled to the bottom and decomposed over the millenia. Until now, the deposits were trapped under frozen underwater sediments.  For several years now, however, hundreds of  vertical stacks of white blobs of melting methane have appeared in blue Arctic lakes, some several feet across, like giant blue lava lamps, as a warming Arctic has started melting frozen lake deposits, allowing half melted methane bubbles to rise to the surface, trapped under ice. Warmed further through the spring and summer, these blobs melt completely, releasing the potent greenhouse gas into the atmosphere, further accelerating global warming. Since 2010, however, reports Robert Krulwich at NPR online, hundreds of gargantuan blobs, measuring more than a half mile across, have been seen in the Arctic sea, indicating far greater releases of methane. This methane bomb, this self driven system of greenhouse gas release, could dramatically accelerate global warming if it’s not stopped soon, and become  COMPLETELY self-driven and independent of human actions, locking the planet, and us, into dramatically worse global warming.

 

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
