re: #217 Last Mohican

But it’s true, the concentration of CO₂ in the atmosphere really is about 3%. I don’t know about her second point, the one in which man-made CO₂ only amounts to 3% of the 3%.

And anyone who thinks that something can’t be a problem if it only constitutes 3% of the total clearly has not had a lot of experience eating day-old clams.

Uh, no. I don’t know where you got that information, but it’s not correct.

Carbon dioxide in the Earth’s atmosphere:

Carbon dioxide forms approximately 0.04% of the Earth’s atmosphere.
