From someone who knows:

'There may be much more of each (oil & gas) to be found in the rapidly thawing Russian arctic. With regard to global warming, the UN climate change effect maps I have looked at show the US and Europe as major losers with regard to their ability to feed themselves, while Russia appears to be the greatest benefactor, with longer growing seasons and more plentiful rainfall.'
