Concerning the effect of CO2 on plants, a reader notes:
It seems the science on this is in its infancy. Where’s the evidence that plants are currently growth limited by carbon dioxide, for instance? There doesn’t seem to be any evidence that human height is oxygen limited within most normal ranges — or is there? Do people in South Carolina regularly grow taller than people in Colorado and Wyoming, because there’s more oxygen in the air at sea level?
