Lots of straw men striding around there. Last refuge, I guess.

It is this way. There was a huge die-off at the Permian-Triassic boundary. There were a couple of waves of extinctions,initially may have been triggered by volcanoes, but later seems to have been caused by methane which later degraded into CO2. Clathrates probably contributed, but probably weren't the main cause.

Now you can spin, bob, weave and dodge all you want, but those are the facts.

Yes, ending snowball earth meant life bloomed. I am not sure why you think that is so telling. And yes, there were more clathrates then, cold water being sort of important to its formation.

No one claimed that the pulse of greenhouse gasses destroyed life on earth then. That is your straw man.
