The data show water vapor is one thousand to seven thousand times more effective at warming the atmosphere than CO2. The warming effect of CO2 is linear with concentration. CO2 is above its boiling point, and the relationship is linear. Water vapor is below its boiling point, and the relationship with concentration is curved.
The science presented in this study leads directly to the following conclusions:
10.1. This study confirms quantitatively that the warming effect of CO2 is too small to measure, i.e., negligible. In contrast, warming by water vapor is 1,000 to 7,000 times greater than CO2.
10.2. The warming effect of CO2 is linear with concentration, i.e., the number of molecules per cubic meter. In contrast, the warming effect of water vapor with concentration is curved.
10.3. The ratio of water molecules to CO2 molecules is 0.0010 from the top of the Troposphere through the Stratosphere and Mesosphere to the top of the atmosphere. This amount is too small to affect the flow of energy to space significantly.
10.4. The radiation profile at the top of the atmosphere is essentially the same as at the top of the Troposphere.
10.5. Separating water vapor’s warming effect from CO2 by radiation profiles is nearly impossible.
10.6. Comparison of three radiation profiles with the ratio of water molecules to CO2 molecules shows the warming effect of CO2 is negligible.
10.7. The Sun is the primary energy source and its variation controls the Earth's temperature. The Sun determines the Earth's temperature, it is currently in a solar minimum.
10.8. The Hunga Tonga eruption pushed the global temperature past the Paris Accord target of 1.5 deg.C, but this will be a temporary spike. There appear to be no credible negative effects.
