Oozing Methane Blasts Holes in Siberian Tundra

Escaping methane gas has blown at least two new holes in the Siberian tundra in the past few months, according to eyewitness accounts to the Siberian Times and the Russian Academy of Sciences.
Reindeer herders northwest of the village of Seyakha in Siberia's far north reported seeing an eruption of fire and smoke on the morning of June 28 an event caught on seismic sensors at 11 a.m. local time, according to The Siberian Times. Scientists visiting the site photographed a fresh crater blown into the banks of a river.
Researchers also discovered a second, previously unknown crater in the Tyumen region of Siberia this month, the newspaper reported. Local herders told Aleksandr Sokolov, a researcher at the Institute of Ecology of Plants and Animals in Russia, that they'd observed fire in the area of that crater in the winter or early spring.

When permafrost melts, it releases large amounts of methane. According to Russian scientists, this sudden release could have led to the explosions. How fast and how frequently this is happening remain controversial topics in the scientific community, given that Siberia is so remote and unexplored. But scientists do agree that Siberia's permafrost is in danger of melting as the globe warms.
