#5  fwiw,

The event (or events) 251 Million years ago may have been caused by a massive volcanism or an asteroid (or both). Debate on this has been on going for many years.

#4  Trust me, if we could have gotten rid of the human infestation by releasing methane, we'd have done it long ago

Pretty much would have killed every owner of large farm animals and/or ancient pets.

#2  Confuses 2 things. Release of methane from geological structures, and release of methane gas from hydrates.

The potential for large methane release from seabed hydrates is scaremongering by the global warming crowd. It isn't going to happen bar some massive geological event.

A sudden massive release of methane from geological structure is plausible. It may even be enough to significantly raise atmospheric methane levels. It may even be enough to have an effect on the climate since methane levels do seem to have a measureable effect on the global climate (unlike CO2 levels which have no measurable effect).
