Apart from the already above mentioned possibilities for that warming,by reading the article Methane is leaking from permafrost offshore Siberia it is suggestive that one should eventually take also the heat from the wasted burning of the methane into account:

>Gas is released in an area of at least 7500 m2, with gas flares extending up to 25 meters in the water column.

There is another thing I would ask into the round here. There is a german radio documentary about gazprom facilities in northern Siberia, around the city of Novy Urengoy which I recently listened to. In that documentary they report amongst others about a preschool where they serve oxygen cocktails, because the "northern air contains less oxygen". I don't know - this cocktail serving might just be a trick to make the preschool more attractive....but may be not.

Does someone know about oxygen concentrations in that region?

I have sofar found only ocean oxygen concentrations and I don't know however how much this is related to the air surface concentrations. (see also phytoplankton decline)But by looking at an ocean oxygen map (please click on "show figure", I couldnt find a direct link to the map) it looks (?) as if there is actually slightly more oxygen rather than less in some northern regions....however not around the gas fields. In particular if I compare that with the map from 2009 then it seems that ocean oxygen saturation dropped quite dramatically around the gas fields. (By the way: similar things can be reported about some Canadian regions). If air oxygen levels are eventually already generally low then little differences may make a dramatic difference....and the impact on children would eventually (?) be higher than on adults.

In that context John, I would like to remind you again of that post.
