Methane (greenhouse gas 25x potent as CO2) bubbles out 5x faster. Warmer air thaws Arctic soil, 50 bil tonnes may be released
Researchers believe the Arctic Ocean seabed is thawing in patches and releasing greenhouse gases. Methane, trapped in the permafrost, 25 times more powerful than carbon dioxide, is bubbling out of the frozen arctic faster than expected.
Researchers ignite a bubble of methane on Alaska’s Steward Peninsula.
Methane is leaking from the East Siberian Arctic Shelf into the atmosphere at an alarming rate. The amount leaking from this locale is comparable to all methane from rest of the world's oceans put together. Methane is a greenhouse gas more than 30 times more potent than carbon dioxide.
