They deal with that. See:
The mechanism also might explain other extinctions and climate perturbations (ice ages) and even the Biblical flood
And here I thought there was no evidence for a Biblical flood! Guess, all that gas rose to the top, produced condensation, and it rained sulphur water for 40 days and nights killing all the animals and people not on the ark. And here I thought they drowned. They just got gassed.

You mean the dinosaurs were into smoking and lighting farts?

Why sweat extinction? Just wait a bit and a bunch of new critters, new and improved, will evolve.

I have little doubt there will be another methane-driven eruption -- though not on the same scale as 251 million years ago -- unless humans intervene."
Unless humans intervene....what a dope. I suppose we could try to mine all those methane hydrates. It's also self-serving to posit an explosion of methane as opposed to an asteroid strike as a cause for the extinction. It's more likely that an oceanic asteroid strike was responsible for the liberation of methane gas from the hydrates than that dissolved methane somehow just happened to be spontaneously released and ignited.

General, that is just a blowhard. Not useful and unlike the very useful methane producing south end of a north bound cow.
Methane hydrate is a very interesting compound.
Methane Hydrate
WHAT do you get when you combine water and swamp gas under low temperatures and high pressures? You get a frozen latticelike substance called methane hydrate, huge amounts of which underlie our oceans and polar permafrost. This crystalline combination of a natural gas and water (known technically as a clathrate) looks remarkably like ice but burns if it meets a lit match.

It is indeed interesting, and sounds kind of dangerous as well.
Enough dissipates and it can topple an Oil rig? and if it disaccociates, you have enough methane to cause quite an explosion.
But if we could somehow harvest this stuff, the possibilities are endless. And Methane burns cleanly, so that would make it very advantageous!!
Cool link....

But if we could somehow harvest this stuff, the possibilities are endless.The quantities of the compound are amazing. --->By some estimates, the energy locked up in methane hydrate deposits is more than twice the global reserves of all conventional gas, oil, and coal deposits combined..
According to this page World Estimated Recoverable Coal we have 1,083,259 million short tons of coal alone.
