Carbon dioxide comprises .02% of the earth’s atmosphere. I think we’ll survive.

Hmmmm. When you see a sandwich wrapped up and the wrapper states “DO NOT EAT WRAPPER!”, you gotta wonder if we will. LOL!

0.042% up from 0.028%. That rise is mostly manmade. It is also very beneficial, 0.03% is far too low. It means that an ice age would lead to 0.15% or CO2 starvation, unique in earth's history. To think we should return to that is pure insanity.
