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.
It’s “settled”, that it was hot. ;-)
