it is important to note that half of the CO2 in our atmosphere is produced by our exhalations and those of our animals [source:gaia's final warning]...so indeed not only would ceasing all industrial activity be required to stop increasing CO2...we would also have to drastically reduce population. even then, there is enough CO2 already in the atmosphere to move the temperature to a new steady state which could take thousands of years to change we are increasing population when we should be enforcing a global one-child policy
