Not likely, since increased carbon dioxide would eventually result in more plant biomass, you'd wind up with a subsequent increase in atmospheric oxygen, and subsequently an increase in animal biomass. If something catastrophic happened that suddenly killed an existing ecosystem and the air and water vapor currents in the local climate changed enough to prevent new growth you could wind up with something like that.
