There’s been a lot of worry-buzz in the usual circles over methane plumes bubbling up in the Arctic related to this NSF press release:
Press Release 10-036
Methane Releases From Arctic Shelf May Be Much Larger and Faster Than Anticipated
Thawing by climate change of subsea layer of permafrost may release stores of underlying, seabed methane

The permafrost of the East Siberian Arctic Shelf (an area of about 2 million kilometers squared) is more porous than previously thought. The ocean on top of it and the heat from the mantle below it warm it and make it perforated like Swiss cheese. This allows methane gas stored under it under pressure to burst into the atmosphere. The amount leaking from this locale is comparable to all the methane from the rest of the world’s oceans put together. Methane is a greenhouse gas more than 30 times more potent than carbon dioxide.

To his credit, Andrew Revkin of the New York Times inquired with the field researchers on the methane bubbles. He writes:
Shakhova and Semiletov, whose earlier analysis of methane in the region was published in Science last year, had been unavailable for comment when I was preparing my piece, as they had gone on vacation shortly after their presentation. When they were back on the grid they got my e-mail inquiries and saw the post. Their response clarifies their differences with other research groups and emphasizes the importance of critically evaluating scientific findings before rushing to conclusions, either alarming or reassuring. One clear message, which I endorse, is the need to sustain the kind of fieldwork they’re doing.
The reply from Semiletov and Shakhova is enlightening and is the QOTW:
We would first note that we have never stated that the reason for the currently observed methane emissions were due to recent climate change.
In fact, we explained in detail the mechanism of subsea permafrost destabilization as a result of inundation with seawater thousands of years ago.
We have been working in this scientific field and this region for a decade. We understand its complexity more than anyone. And like most scientists in our field, we have to deal with slowly improving understanding of ongoing processes that often incorporates different points of views expressed by different groups of researchers.
Do you think Joltin Joe Romm, who agreed with the story by Gillis (but panned Revkin’s story then) before the clarification…
Carbon Time Bomb in the Arctic: New York Times Print Edition Gets the Story Right
Writing:
The NYT would seem to be schizophrenic on this crucial topic, but Gillis clearly has the story right and it isn’t reassuring at all.
…will carry now this clarification? It seems schizophrenic interpretations my not be NYT’s fault at all, especially since the field researchers have clarified on record that they don’t see “climate change” to be involved at all.
Don’t hold your breath.
Kudos to Andrew Revkin for doing actual journalism and going straight to the source.
Of course the bigger problem than Joltin Joe Romm are the non thinking serial media and blog regurgitators. Perhaps WUWT readers can advise them of the correction.

Unprecedented Methane Plumes Bubbling in The Arctic

Update: In case you are wondering what CH4 concentration in the atmosphere looks like, here’s the latest data from NOAA:
The Y axis is Parts Per Billion (PPB) Plot visualizer here. Data here. I noted back in 2006 that CH4 had stabilized, now it is slightly rising again.
Bill Illis in comments adds the Barrow, AK monitoring site in the “permafrost zone … and it is right next to the frozen permafrost/frozen methane beds of the high Arctic.” and notes it is “pretty well flat right now”.

Ow. Mister Expert System Analyst is here again.

Senior Checkout Chick actually. Its amazing what you pick up from talking to the customers. But thanks for the compliment.
Lazyteenager,
The science was always based on Methane levels stabilizing at some point, mostly because of its short life-time in the atmosphere.
The earlier estimates had it stabilizing at about 2400 ppb, I haven’t looked but the IPCC AR5 will certainly use a lower number now. You can probably find it here.
http://www.pik-potsdam.de/~mmalte/rcps/
It appears certain that Methane will stabilize at below 1950 ppb.
“The permafrost of the East Siberian Arctic Shelf (an area of about 2 million kilometers squared)…”
I think you mean 2 million square kilometers. As written, that’s several thousand times all the surface of the earth, oceans and all.
I’m getting the feeling that this is like the ozone hole nonsense: Do these plumes represent something new that is happening or something that we’ve just recently be studying? Does ice/snow hinder methan movement? Those ice shelves argue that methane can outgas at deep pressures so how is surface ice going to stop it’s outgassing?

Bill Illis says: December 27, 2011 at 1:59 pm: Methane levels are not increasing. CO2 is going up, but Methane is not.
Mauna Loa and CSIRO say yes, just a little.
==================================
CSIRO can only detect it because it is so close to the BS emitted by all of our federal government shills in Canberra.
Does anyone have a copy of the Shakhova and Semiletov paper? It’s behind a paywall and I would be grateful for a link to check out exactly what they do say about their hypothesis of 1000yr old inflow of water.
it looks like LT is really very lazy. The fact is that there is no single answer regarding the formation of diamonds.
A quick Google search brought up some interesting information. One paper from Adelaide University challenges what I was taught a very long time ago about the formation of diamonds. The claims in that particular paper seem to be a bit thin.
However, let’s look at the fact that diamonds are made of carbon. This is a truth.
The common element for coal, diamonds oil and even natural gas is carbon!!
As for the point about viability of extracting the natural gas, when you have an oilfield strike like the one in the Gulf of Mexico, or even Westernport Bay for that matter, or the NorthWest Shelf off the coast of West Australia, the extraction of the methane in the form of natural gas should be a no brainer.
@Streetcred, you are not wrong. There is a lot of hot air that is emitted here in Canberra!! The methane that is emitted from on the hill is so bad that the weather has been quite cold!!!!
Here, for those of you interested in a more global view:

from http://gaw.kishou.go.jp/wdcgg/
So, yes, while we had the warmest decade EVAH!, the concentration was actually decreasing.
Methane is apparently produced in the oceans by vast hordes of hypothetical microbes that may be hiding deep within the sediments. I didn’t make that up…
===
Below the seafloor, an unknown but potentially vast biosphere of microbes may be making the methane that percolates upward.
http://www.whoi.edu/page.do?pid=12764&tid=282&cid=2441
===.
There are also vast hordes of spectacularly real microbes that consume most of that odorless gas. For both varieties of microbes, the real and the surreal hordes, we should be grateful to Gaia, the blessed mother of Titan.

I nominate this “Quote of the Week” as best ever “Quote of the Week.

I agree it’s beyond the level of your standard run of the mill QOTW and even beyond “Quote of the Month”(QOTM).
Therefore, I recommend Anthony add this to the contenders for Quote of the Year (QOTY).
Raise your hand if you didn’t think this degassing didn’t happen during every interglacial period using the same process.

Also has anyone done any research on the amount of methane consumed by lighting?
Are you thinking of Catatumbo here, the cloud to cloud lightening? http://matthew-miller.suite101.com/the-worlds-largest-lightning-storm-a148124
There’s been very little research done on this phenomenon at all, but certainly a good place to investigate methane feeding lightening. What I find fascinating is the regularity of it, it disappears for a few months at the beginning of the year and then comes back. If you do any searches on it be aware there’s someone called Quiroga an over-excited environmentalist who’s been playing on the theme the ‘lightening has ‘disappeared’, shock horror, but it always does around jan-march and others are pissed off that reporters ignored that bit –
“Methane is a greenhouse gas more than 30 times more potent than carbon dioxide.”
It sounds a bit like a CO2 comedown, too. I note that the flattening of methane in atmos coincides with flattening in sea level rise and flattening in global temps over the past dozen years or so.
@Mooloo December 27, 2011 at 4:01 pm:
Ah, but 2,000,000 x 2,000,000 km sq is SO much cooler – like almost EIGHT THOUSAND times the surface area of Earth. Ginormous, indeed! Hey, but what is a misplaced decimal or such, among friends? (hahah – good thing I checked on my calculator – I almost missed a decimal place myself!)
Anyone interested in Methane levels over the last 800,000 years.
So that we can see if high temperatures in the Arctic will cause a Methane apocalypse.
Nope.

Today, thanks to man’s use of natural gas (which is mostly Methane), CH4 is up to 1900 ppb. In the last interglacial, the Eemian, when temperatures in the Arctic rose to about +4.5C higher than today, Methane only increased to 726 ppb (while the coldest part of the ice ages background level is about 400 ppb).
The highest Methane levels, at about 800 ppb, occured during an ordinary interglacial 300,000 years ago. The long interglacial at 400,000 years ago, when the southern third of Greenland’s glaciers melted out and small trees even grew in the southern interior of Greenland, only got to 725 ppb.
So no soup/catastrophe for you/AGW’ers.
Please copy and post this chart around the net every time this scary scenario gets brought up.

Muñoz believes methane may increase the conductivity of the air over Catatumbo”
This statement definitely requires an explanation. The electronegativity of H is 2.1 and for C it is 2.5. What this basically means is that the attraction for shared electrons is very close so there is only a very slight polarity. However perhaps of greater importance is that the CH4 molecule is tetrahedral so there is an angle of 109 degrees between all H’s and the C. This complete symmetry means the molecule as a whole has no charged ends.

Thank you Werner (though it’s all a bit above my paycheck), does the water in the atmosphere have any bearing on it? I ask because the lightening is cloud to cloud.

Those are all great points that should be taken into account.
Andrew: I mean if Howard Hughes can ‘extract Manganese nodules’ from the bottom of the sea in the 1970′s…
Don’t know if HH ever actually extracted anything but a soviet submarine (almost). Never know what you come across when you go grubbing about the bottom of the sea… : > )
Has anyone published the yearly loss of natural gas from local and high pressure long distance ( 200+ psi) pipelines? There are gas leaks being repaired all the time around these parts (Boston) but I suspect that there are many many more leaks are going by undetected.
There was one leak near where I work along an abandoned RR track that leaked for a half year. Everyone in the neighborhood could smell it, many people reported it to the local gas company and they would come and check the local lines which were fine. It turned out to be a high pressure line and it didn’t get any service until someone called the local fire department, (a city north of Boston) to point out the bubbles coming up through the standing water and ice in early spring. At least six months of leaking before any action … and that was in the middle of a CITY! So there have to be a lot leaking out in rural areas that will never be detected until the pipes completely split or the leak catches on fire.

I didn’t know people like you still existed! Have you actually pondered the implications of this ‘cherry picked fact’ with respect to your delusion?: http://www.woodfortrees.org/plot/hadcrut3vgl/from:1997
You have it 180 degrees backwards. There is no credible empirical data to support the theory that CO2 from humans causes ANY measurable increase in global temperature… NONE! There are mountains of empirical evidence that CO2 has little or no affect on global temperature at all, (such as that Hadley CRU data above showing no significant warming for over a decade). You are the one in denial.
Tshane3000: I think Bill Illis’ post was supposed to be ironic.
Looks to me like we ought to be drilling wells and sucking it up to burn it into a less risky form, CO2, for the good of the planet, of course 😉
BTW, CO2 LIQUID bubbles out of the sea floor at depth and near the mid ocean ridges / volcanoes. How much? No one knows…
