Please,Please,Please,Please,Don't change the atomic weight of carbon to be lighter than oxygen -I'm sick of the following image being used in advertising for carbon taxes.

Everbody KNOWS that the balloon will instantly fall to the floor as if it is lead -this is just false advertising.(I don't know about the U.S. but here in Australia this is a blatant example of false advertising some companies here get away with.)

Carbon is already lighter than oxygen. Did you mean hydrogen?
