On a long enough scale the carbon we added to the atmosphere will get sequestered again, and using more efficient plants everywhere would cause a swing the other way to a reduction in CO2 and global cooling. That's a much easier and slower problem to deal with though. That would be so far in the future though we can't even imagine what the earth would be like, or what we would be capable of, or what the population would be. Hopefully we decided it was important to leave large natural spaces on the planet.
