Talk:Carbon dioxide

Atmospheric CO2 has increased about 25 percent since the early 1800s, with an estimated increase of 10 percent since 1958

Anyone know what it increased from? Like, from 0.04% to 0.05% or something? Ed Poor

Well, everything except nitrogen, oxygen, and argon totals under 1 percent, and is generally measured in parts per million. Those concentrations are significant. Vicki Rosenzweig, Monday, June 24, 2002

Well, I'm getting better at this Internet-thingie. I just found the answer to my own question!

"Carbon dioxide, CO2, is one of the gases in our atmosphere, being uniformly distributed over the earth's surface at a concentration of about 0.033% or 330 ppm." [1] (http://scifun.chem.wisc.edu/chemweek/CO2/CO2)

Anyone know the ammount of CO2 that nature produces each year? Animals and humans? How much does it consume? 144.173.6.79[?]
