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.

So,Einstein. What is the ideal carbon dioxide levels for the earth?
