I think probably more. My understanding is that no one knows exactly what caused the Permian Extinction event, it could have been volcanic activity, it could have been a massive meteor strike. We do know that a massive amount of carbon was captured by the life on the planet and subsequently sequestered away from the atmosphere in the earthen strata from that era. We also know that life on the planet is dynamic and evolves to accommodate the mean living conditions on the planet over time. It’s sudden change, the change that happens faster than evolutionary time that causes problems for existing life forms, particularly those with longer lifespans. If the food web crashed tomorrow flooding the atmosphere with hydrogen sulfide gas, the microbes would have those conditions adapted to in a matter of days. We would be wiped from the face of the earth as a species in hours. Managing global CO2 levels doesn’t mean moving away from hydrocarbon fuels, it does mean stop pulling them out of the strata at a rate the evolutionary processes on the planet cannot adapt to. The oceans are turning to acid as they absorb the CO2 we’re putting into the atmosphere with industrial activity, literally martyring itself for our short term survival. The tipping point is fast approaching. The corals say it all. We won’t survive a oceanic food web crash.
