Water Vapor is by far the most significant Green House Gas (GHG)


The only defined mechanism by which CO2 can affect climate change is by affecting outgoing radiation between the wavelengths of 13 and 18 microns.

  1. Incoming visible radiation has a wavelength between 0.4 and 0.7 microns, and is consistent with a black body of temperature of around 5,200 degree C (the Sun). CO2 is transparent to these wavelengths.
  2. The earth emits IR mostly between 6.5 and 12.5 microns, with a peak near 9.5 microns. 9.5 microns is consistent with a black body of temperature  18 degrees Celsius. CO2 is mostly transparent to those wavelengths.
  3. CO2’s absorbs between 13 and 18 microns, with a peak near 15 microns. Those wavelengths are consistent with a black body of temperature -80 degrees Celsius.
  4. H2O is by far the most significant GHG, and absorbs across the IR Spectrum.
  5. CO2 absorbs a small fraction of the IR Spectrum having 3 narrow peaks at 2.7, 4.3 and 15 microns, all of which largely miss the peak outgoing  IR radiance of the earth at 9.5 microns.
  6. H2O largely absorbs the same IR spectrum as CO2, and is at much higher concentrations in the atmosphere. H2O IR absorption makes CO2 contribution to warming inconsequential.

600 Million Year Geologic Record



  1. The current CO2 level of 400 ppm is at the extreme low end of the past 600 million years. Plants and therefore most life will die if CO2 falls below 180ppm.
  2. CO2 has been as high at 7,000 ppm, or 17.5x today’s level and the earth has NEVER in 600 million years experienced catastrophic global warming, NEVER.
  3. The earth fell into an ice age when the CO2 level was at 4,000 ppm, or 10x the level of today.
  4. Modern reefs and sea life developed over the past 220 million years when CO2 and temperatures were much higher than today. Coral Reefs only exist in the warm parts of the oceans and rely on dissolved CO2 to form their CaCO3 shells.
  5. There is no defined mechanism by which CO2 can allow the globe to cool, the only defined mechanism it to trap outgoing radiation between 13 and 18 microns.
  6. Over the past 600 million years, CO2 and Temperature simply aren’t correlated, and regardless of the level of CO2, temperatures cap out around 22 Degrees C.
  7. CO2 caused ocean acidification is simply not a possibility due to the huge buffering capabilities of the ocean, once again, the coral reefs developed during periods of much higher CO2 levels.
