On the other hand the event extinguished more species than the comet that killed the dinosaurs. Maybe those amphibians just had a good strategy for dealing with the heat.
However! If it was cool enough on places far from Siberia, then it’s obvious that this lava lake caused high temperatures around it. Not the “Global Warming caused by CO2 buildup, 250 million years ago”.
Then, big amphibians could survive in Antarctica, for example.
Amphibians were always fresh water creatures. And if the oceans were hot because of this super-volcano, some distant ponds and lakes could be—just warm.
Hm, the trouble is that this doesn’t account for the insulating effect of air, or a thin cool surface layer. A layer of air can reflect a lot of radiated heat right back into its source. Dare I say you might need something like a climate model to decide this?
Why was so hot, back then?
Large amphibians survived, so it couldn’t have been that hot.

It’s “settled”, that it was hot. ;-)

In those climate models we have, CO2 is the most important player.
All those models (about 60 of them) have failed to predict non-higher temperatures since 1997, despite more CO2 in the air.
We would need a model without Arrhenius, if you ask me.
