This story popped up on yahoo now, but all I have seen so far, references Igor Semiletov of the Russian Academy of Science

Here is a little more information on Dr Semiletov.
It looks like this is news, a recent discovery, and there isn't much information. We don't know if this is something that had been going on
undetected, or a new development. I wonder what kind of effort is being made to look at the extent of these methane plumes, and identify how long
this has been going on.
If this is a recent development, it should be taken very seriously.
The counter argument is that this melting of the permafrost will take more than a century to become a much bigger problem.
The NY Times just released an article yesterday telling everyone not to worry.
A very important research effort has been under way during recent summers in the warming, increasingly ice-free shallows off Russia’s Siberian
coast. There, an international array of scientists has been investigating widening areas of open water that are disgorging millions of tons of methane
To review, the authors confirm “drastic bottom layer heating over the coastal zone” that they attribute to warming of the Arctic atmosphere, but
conclude that “recent climate change cannot produce an immediate response in sub-sea permafrost.” That’s the understatement of the year
considering their conclusion that even under sustained heating, the brunt of the sub-sea methane won’t be affected in this millennium.
This is essentially a summary of what the American Geophysical Union is saying, but how involved are they with the International Arctic Research
Center is not clear.
This is their home page research.iarc.uaf.edu...
Which is the group Dr Semiletov works for.
If this is a new development, then things could get very bad, very soon.
The American Geophysical Union states that the bulk of the methane is roughly 200 meters below the sea floor, but they don't speculate what will
happen when the bulk of this methane is hit. Will that be the game changer?
Now we have these methane volcanoes erupting. What happens if these volcanoes dig holes that reach 200 M depth? Are we going to see a huge surge in
methane emissions? This claim that it will take at least over a century for the bulk of the methane to be tapped, does it consider methane volcanoes
drilling down into the sea bed? How much risk does this add to the equation of drilling for oil in the Arctic? 200 meters is pretty shallow. The
recent gulf incident clearly demonstrated that the people in charge of these operations don't know what they are doing, and don't seem to care.
My guess is that nobody has a clue about what is going to happen.
It could be game over folks.
