That ignores the diversity increases during the late Eocene when CO2 was more than double what it now is.

"Geological and geochemical evidence indicates that the Antarctic ice sheet formed during the Eocene–Oligocene transition 33.5–34.0 million years ago. During maximum ice-sheet growth, pCO2 was between 450 and 1,500 p.p.m.v., with a central estimate of 760 p.p.m.v."

Mass extinctions create added CO2 when all the dead biomass is recycled by oxygen back into the atmosphere.

You are a mighty, ignorant and idiotic dung-tard. Seriously??? Do you have an ounce of intelligence?

The research looked at peaks in biodiversity loss and their relationship with atmospheric CO2, finding 50 events over the last 534 million years that can be considered mass extinctions.

Please disclose who sponsored this "research". It is enlightening to google: "wind turbine graveyards", "solar panel graveyards" and "China's monopoly of slave labor produced wind turbines and solar panels." Thank you.
