    'Fountains' of methane 1,000m across erupt from Arctic ice
    Daily mail ^ | 12.13.2011 | n/a

    The Russian research vessel Academician Lavrentiev conducted a survey of 10,000 square miles of sea off the coast of eastern Siberia. They made a terrifying discovery - huge plumes of methane bubbles rising to the surface from the seabed. 'We found more than 100 fountains, some more than a kilometre across,' said Dr Igor Semiletov, 'These are methane fields on a scale not seen before. The emissions went directly into the atmosphere.'

    Climate Change: The Next Generation: Semiletov tells AGU that, if released, 1 percent of ESAS methane could cause runaway warming

    Semiletov points out that geologists estimate that the amount of methane stored beneath the Siberian shelf to be on the order of 2,000 gigatons. (Keep in mind that methane is a greenhouse gas 20-times more potent than CO2, and that total carbon emissions today are in the range of eight gigatons a year.) Semiletov thinks that if just 1percent of the ESAS methane is released, it will push total atmospheric methane up to 6 parts per million, and he cites researchers such as David Archer in arguing that this would push us past the point of no return toward runaway global warming.
    Leading climatologist James Hansen also gave a talk at the conference, to his usual throng of thousands, about the threat of runaway global warming and the need to phase out coal plants. He happened to mention that the global atmospheric record showed a slight fall-off in methane for 2008, so I asked him if he was less concerned about this particular threat to a stable climate. Hansen said that on the contrary, the paleontological record probably isn’t a good guide to global methane release, because “even though evidence of releases might look like spikes on a plot, they still happened over thousands of years. Human forcings are happening so fast they don’t allow for negative feedbacks.”

    Looks as if things are going to change even faster than the 'alarmists' have been predicting.

    Methane hydrate is frozen solid methane (natural gas) combined with water (ice). It exists on and beneath the sea floor around continental margins. Tiny amounts of the gas can seep out through cracks in the hydrate (frozen lattice).

    In the cold Arctic waters and under high pressure, methane hydrate occurs below permafrost, making it stable but particularly vulnerable to global warming, which destabilizes the solid hydrate, releasing methane gas. It is especially vulnerable in the shallow East Siberian Arctic shelf (ESAS), where 90% of Arctic methane hydrates are situated.

    Unexpectedly a team of Russian scientists researching Siberian methane emissions have discovered that ESAS hydrates are already venting methane to the atmosphere.

    A call for immediate action. Useless, of course, except in the context of the scientists being able to state "We told you so".

    NGU brochure

    Nothing will be done, and we will see all of this happen. The 'tipping point' is passed. As individuals, and as a nation, we need to plan for consequences. That is not going to happen, either. Except for a very few people, none will consider this serious until it is directly affecting them. Even then, many will insist it is 'cyclic' and has nothing to do with the GHGs that we put into the atmosphere.

    Too late. Its like stopping a runaway locomotive, once you apply the brakes it is already too late and takes forever to stop.

    Look out your window and note that the sky is not falling. Apply some lotion to your hands which are undoubtedly raw and chapped from the incessant hand wringing and take a few deep breaths and try to understand that you have been hoaxed.

    Do you really believe that the sea bed has never burped methane before? Methane has no more capacity to warm the atmosphere than CO2.

    Jeez, it didn't happen in the 1930's (when it was warmer) it didn't happen in the MWP (when it was way warmer, and it didn't happen during the RWP (when it was likewise way warmer). I say get a team down there and cap the plumes at their source and start generating some power with it!

    LOLOLOLOL.....just more retarded anti-science drivel from the forum's resident bogus bloviater and tragic Dunning-Kruger Effect victim.
