O₂ concentration would fall with the rise of C0₂ concentration, I guess that's what you expect?

Well, CO₂ is at 415 ppm currently, up from 200 before mankind.
O₂ is at about 210,000 ppm. Maybe that was 210,215 ppm back then. It is less now... about 0.1 %, or 0.02% of the whole atmospheric content.

Fire is a chemical reaction triggered by heat. More heat, more fire. Even at 0.02% less oxygen.

For education go to people unlike yourself.
