In other places in Russia the warming climate is thawing the permafrost
(especially in peat deposits) and releasing great amounts of methane.
Methane is
50 times as efficient a green house gas as carbon dioxide. Thaw enough
permafrost and you will greatly speed up the accumulation of green house
gases.
