Permafrost Bubbles are Leaking Methane 200 Times Above Normal
The swelling pockets in the permafrost – revealed this week by The Siberian Times – are leaking ‘alarming’ levels of ecologically dangerous gases, according to scientists who have observed this ‘unique’ phenomenon. Some 15 pockets have been found on the Arctic island, around one meter in diameter.
Measurements taken by researchers on expeditions to the island found that after removing grass and soil from the ‘bubbling’ ground, the carbon dioxide (CO2) concentration released was 20 times above the norm, while the methane (CH4) level was 200 times higher.
One account said: “As we took off a layer of grass and soil, a fountain of gas erupted.”
