I can prove that is false.
Right now the CO2 levels are 387 PPM, that is 0.0387%. If the levels were 1,000 times higher, they would have been at 38%. CO2 exposures of 4% and above are essentially immediately fatal - at best you might live a few minutes. This means even if levels were only 100x greater than today, they would have been at 3.8%, which is basically fatal within a few minutes of exposure. He's claiming they were even 10x higher than that?!!?!?!!?
When I say fatal, I mean nearly all animal lifeforms, especially mammalian life forms. Baby chicks and canaries (not mammals) die at 1-2% CO2 concentrations.
I didn't bother to read any other junk from that fraud. If he's that erroneous in one of his claims and can be so easily debunked, he isn't even worth considering.

I don't believe if you oxidized all the carbon on earth it would achieve that level. OTOH, before life on earth, you and I have no idea how high the rate was. It would contradict the evidence, however, to think there was an ice age at that point.
Nonetheless, if all carbon in and on earth were oxidized it probably could achieve such a level. That doesn't explain what happened to all that oxygen required to oxidize it. Oxygen being about 21% of the atmosphere.
BTW, the fatal rate in humans for CO2 is roughly 7%. Above 5% is considered very dangerous.
