Arctic Shelf Leaking Potent Greenhouse Gas
The frozen cap trapping billions of tonnes of methane under the cold waters of the Arctic Ocean is leaking and venting the powerful greenhouse gas into the atmosphere, new research shows.

Getting smart to cut farm emissions – Environment – NZ Herald News
Farm scientists at a new multi-million-dollar research facility believe they can cut the carbon footprint of milk by 20 per cent – even without using the latest emerging technologies.
As Arctic Ocean warms, megatonnes of methane bubble up
It’s been predicted for years, and now it’s happening. Deep in the Arctic Ocean, water warmed by climate change is forcing the release of methane from beneath the sea floor.
New worries on Arctic permafrost thaw
A rise in concentrations of a powerful greenhouse gas over the Arctic after a decade of stability is stirring worries about a possible thaw of vast stores trapped in permafrost, experts said.
Levels of methane in the atmosphere rose 0.6 percent in 2008, according to preliminary data from the Zeppelin station on a remote island in the Norwegian Arctic, after a similar 0.6 percent gain in 2007, Norwegian officials said.
The 2007 rise outpaced a global rise in methane of 0.34 percent to a new record high after levels had been stable for about a decade. World data for 2008 are not yet available.

Is global warming an abstract threat?
To be sure, carbon dioxide and other greenhouse gases trap heat in the earth’s atmosphere, but they remain invisible to the human eye, unlike smog, diesel soot and other air pollutants.
Scientists still struggle to get the public to pay attention, despite an avalanche of peer-reviewed studies showing th
Methane released in the Arctic could raise global temperatures
The first evidence that millions of tonnes of a greenhouse gas 20 times more potent than carbon dioxide is being released into the atmosphere from beneath the Arctic seabed has been discovered by scientists.
