Afsmeltningen af den Arktiske havis og den generelle opvarmnign af polarregionerne har nu fået den Sibiriske undersøiske permafrost til at tø, og derved frigives den metangas der hidtid har bundet i usete mængder.

Uddrag:

The scale and volume of the methane release has astonished the head of the Russian research team who has been surveying the seabed of the East Siberian Arctic Shelf off northern Russia for nearly 20 years.

Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region.

"Earlier we found torch-like structures like this but they were only tens of metres in diameter. This is the first time that we've found continuous, powerful and impressive seeping structures, more than 1,000 metres in diameter. It's amazing," Dr Semiletov said. "I was most impressed by the sheer scale and high density of the plumes. Over a relatively small area we found more than 100, but over a wider area there should be thousands of them."

Nu venter vi blot på at klimaændringsbenægterne kommer med næste runde udenomssnak og arrige udfald mod IPCC og forskerkredsen, så vi kan sidde med hænderne i skødet nogle år endnu og nægte at verden ændrer sig omkrring os.
