Orders of magnitude higher CO2 than what the “researchers” were discussing.
You’re the one that suggested it should have been the other way around, whatever the origin of the increased CO2 levels.
It would have to have been ‘orders of magnitude’ less, though, wouldn’t it, since there was no mass extinction event as happened after the Permian era?
