What happened at the end of the Permian?

volcanic eruptions elevated CO2 and sulfur dioxide to the point that global warming occurred.
Warming interfered with oceanic currents producing marine anoxia.
Marine anoxia caused blooms of cyanobacteria that then invaded terrestrial environments.
Cyano killed plants and thus destroyed all food webs not based on detrivores.
Mass collapse of food webs destroyed megafauna and marine biotas.

eventually climates stabilized, but by the time it was done almost everything was dead.

My random guess is a something that poisoned the water. Hell, it could be something we wouldn't even think of today, that we have complete resistance to.

something big

Holy shit...

So fucking underrated

There was also an extiction in the middle of this period wich was as big as the Cretaceus so the Earth was still recovering from another extiction.

>What happened at the end of the Permian?

Organic sediment had accumulated over a very long time.

A new gene appeared in methanogenic microbes that increased their metabolism(and therefor, methane production), this new gene was rate-limited by nickel.

The siberian traps volcanism however caused nickel fertilization of the oceans at a massive scale, this caused an enormous population boom and massively increased methane production.

Whatever actually caused the extinction after this is unclear, global warming? Disrupted oceans with lower oxygen output? Something else?

But we know the methane production was way too fast to be due to some thawing effect, it had to be sourced from some organism going wild.

Volcanic activity wasn't enough to cause significant global warming. CO2 was already at 900 ppm and 2 degrees higher than current.

Triassic was at 1750 ppm CO2 and 3degrees higher. CO2 higher probably due to the methane liberation in late permian.

The components required for a global warming mass extinction is missing. If volcanism was the reason it would've been an aerosol cooling disaster(millenium without a summer?) and not global warming.
