Going to throw this in the mix - this is definitely something to think about when considering global warming. Consult Google for these numbers - I checked a couple sources to find rough estimates. Please correct me if I made an error. Obviously, this is a gross simplification... The atmosphere has 5×10^18 kg of mass. That is 5,000,000,000,000,000,000 kilograms of mass for people who like to see the zeros. Just by breathing, the human race produces about 2.2 trillion kilograms of CO2 annually. However, humans are only a fraction of the earth's CO2-producing biomass, about less than 1/1000 by some estimates. So that means that earth's creatures probably produce over 2 quadrillion kilograms of CO2 annually! Human technology (cars, power plants, etc) produce 27.2 trillion kilograms of CO2 annually. Let that sink in for a second - just by breathing, we produce a magnitude greater amount of CO2 than fossil fuel ever will. Wow. So where is it all going? My guess is photosynthesis is doing a pretty good job of keeping things in balance, but I am open to suggestions.
