In his Dec. 4 Newsmax column, done as a letter from Mother Nature to Al Gore, Phil Brennan writes:
This notion that mankind can be forced to reduce atmospheric levels of CO2 by reducing its carbon footprint — I love these disingenuous terms you invent to bolster your shabby case — is sheer nonsense, based as it is on the false notion that human activities are mainly responsible for the buildup of the greenhouse gas CO2 in the atmosphere.
Now Al, you know that the principal greenhouse gas is water vapor which accounts for about 95 percent of all the greenhouse gases floating around out there.
The other 5 percent is composed of carbon dioxide, methane, nitrogen dioxide, and various others including CFCs, with carbon dioxide being by far the greatest greenhouse gas contributor among them at 3.6 percent.
But carbon dioxide as a result of man's activities accounts for barely 3.2 percent of that, thus only 0.12 percent of all the greenhouse gases in total.
