As the "global warming" agenda is pushed, little focus is paid to the real causes, says Rep. John Linder (R-Ga.).

For example:

  • The most prevalent and efficient greenhouse gas is not CO2; it is water vapor, which accounts for about 60 percent of the heat-trapping gases while CO2 accounts for about 26 percent.
  • We currently have CO2 levels of about 380 parts per million parts of atmosphere (ppm); a recent study completed at UC Davis concluded that the amount of CO2 in the atmosphere 300 million years ago was on the order of 2,000 ppm.
  • Methane, another greenhouse gas, has other sources as well; 76 percent comes from wetlands, which produce 145 million metric tons of methane per year during the decomposition of organic material.

The current push to blame humans for global warming is not unlike the debate surrounding the depletion of the ozone layer years ago, says Rep Linder.  It too was filled with misinformation:

  • The world's production of chlorofluorocarbons (CFCs) peaked at 1.1 million tons per year; if 100 percent of that was released it would have added 750,000 tons of chlorine into the atmosphere.
  • That number is insignificant compared to the 300 million tons the oceans yield annually by the evaporation of seawater alone.

Hopefully, as people realize the earth is going through the same cycles of heating and cooling that we have seen over hundreds of millions of years, the global warming myth will do the same, says Rep. Linder.
