    Even if you had some accurate sources ... you still have yet to show why we need to keep this all frozen in the first place.

    Preliminary findings suggest that massive deposits of subsea methane are bubbling to the surface as the Arctic region becomes warmer and its ice retreats

    The first evidence that millions of tons 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.

    The Independent has been passed details of preliminary findings suggesting that massive deposits of sub-sea methane are bubbling to the surface as the Arctic region becomes warmer and its ice retreats.

    Underground stores of methane are important because scientists believe their sudden release has in the past been responsible for rapid increases in global temperatures, dramatic changes to the climate, and even the mass extinction of species. Scientists aboard a research ship that has sailed the entire length of Russia's northern coast have discovered intense concentrations of methane – sometimes at up to 100 times background levels – over several areas covering thousands of square miles of the Siberian continental shelf.

    Methane occurs naturally ... so now show what purpose methane serves in nature.

    Scientists have discovered massive amounts of methane, a greenhouse gas far more powerful than carbon dioxide, bubbling up from the Arctic seabed, according to an exclusive report published today in the U.K.’s Independent. The revelation raises the frightening possibility that vast quantities of methane long trapped below undersea permafrost will enter the atmosphere and set off runaway global warming. Known as the “Clathrate Gun Hypothesis,” the theory is held as a likely reason that 70 to 96 percent of all species on Earth went extinct at the end of the Permian 251 million years ago.

    Aaah ... but mass extinction has always produced better species ... it's why we exist after all.

    Until China and India, the worlds biggest poluters, sign an agreement to curb "Greenhouse Gas" emissions anything we do will just be a drop in the bucket.

    Good luck with that.

    I think we have already passed the tipping point.

    They said that 20 years ago.
