The Permian-Triassic extinction. en.wikipedia.org Recent climate models suggest that such a rise in CO2 would have raised global temperatures by 1.5 °C (2.7 °F) to 4.5 °C (8.1 °F), which is unlikely to cause a catastrophe as great as the P-Tr extinction.[82] However, one theory, popularized by the 2005 documentary Miracle Planet, is that the slight volcanic warming caused a melting of methane hydrate, and this created a positive-feedback warming loop, as methane is 45 times more efficient than CO2 at exacerbating global warming. The Earth, sure. The critters on it, not so much. The planet temp changes on it's own - right now nothing much is happening and even if we attempt to burn all coal and oil we run out before we can possibly do any damage. PS: The critters are doing fine - polar bear numbers are still on the rise.

Oh those...all of which included a serious CO2 spike followed by global warming, right??? And not -if ever possible - the other way around, right? Because that as we all know, only happened during a brief and most recent period of barely a million years, which just 'happens' to be on record... CJ, you still owe me a link to that precious GW and preceding CO2 data from the most recent 500 (-1) million years from your bunch of 'vast...climate scientists' knowing this stuff better than anyone including you and me...
