re: #83 Walter L. Newton

Then how do we find the right balance? I know this may sound silly, but I am honestly asking this… How do we balance out what is too much Co2 and what isn’t. Is there a point that there is not enough Co2 floating around and that causes some other problem… really, can it be a too much, not enough scenario? How do we balance out which parts of the globe should have less Co2, how do we isolate it, it’s not like the planet is divided into nice little parcels that we can manipulate, section by section?

Atmospheric mixing is extremely efficient; I doubt you’d find local variances except around prolific point sources of CO2, like volcanoes. Overall, I’d expect the concentration would even out very quickly, even if one continent were almost exclusively responsible for emissions.

And yes, too little CO2 is bad. Ask any plant. Not sure what the effect might be on climate, although the part of Michigan I’m currently typing from was underneath about two solid miles of ice pretty recently.
