Perhaps I'm missing some part of this; but dosn't this create a
circular argument?  If Methane hydrates were deposited because of
very cold conditions, then presumably a warmer condition is necessary
to release them.  If the warmer condition is a result of Methane
hydrates in the atmosphere, how did they get released to form the
warmer climate?, Or is it that the release just accelerated the
process?
