Water Vapor vs CO2 for Planet Warming
Abstract During the time period when water vapor (WV) and carbon dioxide (CO2) have been accurately measured worldwide, 1988-2018, WV increase has been responsible for the human contribution to Global Warming with no significant net contribution from CO2.
Introduction A useful insight to the influence of WV on planet warming can be obtained from understanding why cloudless nights cool faster and farther when absolute water vapor content of the atmosphere is lower; especially when there is no dew or frost. This simple observation demonstrates that water vapor is infrared electromagnetic radiation (IR) active which makes it a so-called greenhouse gas (ghg), thermalization (ghg molecules absorbing radiant heat from the surface or other ghg and sharing the absorbed energy with surrounding molecules) takes place, and that the misleadingly named greenhouse effect (GHE) exists.
