300 massive methane leaks discovered in the Arctic

An expedition of international scientists in the Arctic made up of Swedes, Americans and Russians discovered 300 sites of massive methane release in the Arctic, the Itar Tass news agency announced yesterday, after an interview with researcher Igor Semiletov.

It was a study that for the first time covered the entire length of the Northern Sea Route and in this way the records of methane emissions were made at the same time in all the Arctic seas, said Semiletov, who integrates the researchers from the International Center for Arctic Studies at the University of Alaska Fairbanks, the Pacific Oceanological Institute and the Russian Academy of Sciences.

The scientist expressed concern that this will mean very high levels of methane in the atmosphere.

Methane is a greenhouse gas more than 30 times more powerful than carbon dioxide. On land, it is released when previously frozen organic matter decomposes, instead "at the bottom of the sea, while the underwater permafrost remains frozen, a lid forms, effectively trapping methane underneath," reported the University of Alaska Fairbanks, according to an Arctic report by Natalia Shakhova and Semiletov from November 2013.

“However, as the permafrost is thawing, holes develop, allowing the methane to escape. These emissions can be larger and faster than those that result from decomposition, ”Shakhova described.

The researcher at that time highlighted that “the Arctic platform of Eastern Siberia is ventilating at least 17 teragrams of methane into the atmosphere every year. A teragram is equal to 1 million tons ”.

“It is now on par with the methane being released from the Arctic tundra, which is considered to be one of the main sources of methane in the Northern Hemisphere,” Shakhova said and concluded that “Increased methane releases in this area it is possibly a new factor of climate change ”.

On August 11, the Arctic Research Center released a video called "Arctic in Emergency", due to the release of methane and its importance in climate change.

Natalia Shakhova explained “how the 'methane bomb' is produced in the underwater permafrost in the Arctic (See images and statements at 13:56 in English) and why the release of methane in the Arctic is a major turning point on climate change on a global scale ”. The video begins by showing the exponential increase in weather disasters.
