STOCKHOLM (AFP) — Methane, a potent greenhouse gas, is leaking from the permafrost under the Siberian seabed, a researcher on an international expedition in the region told Swedish daily Dagens Nyheter on Saturday.
"The permafrost now has small holes. We have found elevated levels of methane above the water surface and even more in the water just below. It is obvious that the source is the seabed," Oerjan Gustafsson, the Swedish leader of the International Siberian Shelf Study, told the newspaper.
The tests were carried out in the Laptev and east Siberian seas and used much more precise measuring equipment than previous studies, he said.
Methane is more than 20 times more efficient than carbon dioxide in trapping solar heat.
Scientists fear that global warming may cause Siberia's permafrost to thaw and thereby release vast amounts of methane into the atmosphere. The effects of global warming are already most visible in the Arctic region.

Be great to sell that as cure for climate change, do a billion times more good than any carbon market.Penguin wrote:..As one of our professors said when asked what is the most important thing to do to save our planet now...
He said " We must absolutely protect every remaining forest, every remaining mire, and aggressively plant more forests, and return dried mires to natural wet state, and we must seed plants that can improve soil and capture CO2 into the soil, everywhere on Earth". Forests, plants, thats the lungs of our planet. And thats going fast - and as temperature rises, plant diseases and pests could potentially devastate large areas of the northern hemispheres boreal forests - from Finland to Russia to Canada and States.
Greenpeace don't write AP stories, so no wonder they don't get to make a case (hot off the press). Suspect this what referring toBen D wrote:On top of that, researchers were investigating "alarming" reports in the last few days of the release of methane from long frozen Arctic waters, possibly from the warming of the sea, said Greenpeace climate scientist Bill Hare, who was attending a climate conference in Ghana.
This really is a 'hot of the press' credible substantiation of the Greenpeace scientic approach to making a case.

Major ice-shelf loss for Canada
The ice shelves in Canada's High Arctic have lost a colossal area this year, scientists report.
The floating tongues of ice attached to Ellesmere Island, which have lasted for thousands of years, have seen almost a quarter of their cover break away.
One of them, the 50 sq km (20 sq miles) Markham shelf, has completely broken off to become floating sea-ice.
Researchers say warm air temperatures and reduced sea-ice conditions in the region have assisted the break-up.
"These substantial calving events underscore the rapidity of changes taking place in the Arctic," said Trent University's Dr Derek Mueller.
"These changes are irreversible under the present climate."
The lowest point since satellite measurements began in 1979...
