The end-Permian version of this had, if memory serves, a "natural" warming
after the methane hydrates were trapped. This released the methane, causing
an increased heating effect. The model in both cases assumes cold period
followed by warm period in a cyclic system.
The source of the methane in the methane hydrates has not yet been
discussed. A huge amount of organic matter is required to produce the
methane levels suggested.
Let's hope I remembered that correctly
