re: #155 SixDegrees

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.

I here we’re supposed to be under about two solid miles of ice after the storm tomorrow. :)
