The math is against the concept. The CO2 increase of even 500 ppm would not have a significant displacement of O2 levels, which are between (20%) 200,000 ppm and (21%) 210,000 ppm.

Yeah, you're right about the math but I would add one qualifier, according to the article one unit of CO2 added to the atmosphere removes 3 units of O2. Taking another tack I'm wondering what happens if we lose a serious amount of photosynthetic capability due to forest clear cutting and increasing ocean dead zones etc.

People live permanently on this planet from below sea level to above 18K'. I live at 8,880' with substantially less O2 than right and left coasters and flat landers. In the first half of the resequestration of CO2 time after thermageddon with most life dead and rotting at high temperatures I think the O2 level could drop to 19% or less. Still not enough to affect animal life resurgence in the several million years after total resequestration. Burgeoning new plant species could bring it up to 23% before back to 20-21%.
That is with the likelihood people will not stop fossil fuel use soon enough and will also not burn enough of it for a Venus effect. Seeing the population crash, AGW, other pollution and depletion effects will keep population levels low until thermal max in 500 years or so. :-({|= :mrgreen:

Unless you subscribe to the theory the lizard aliens set up oxygen generators in what is now Antarctica when they began the terra forming in preparation to colonization of Earth. :mrgreen: #-o
