As a physicist, and judging from what you write in your posts, I probably know a great deal more than you about the greenhouse effect, so I’m writing this not to teach you, but to help explain to others who aren’t scientists why your arguments are not correct. The greenhouse effect is due to absorption of energy by molecules which can re-radiate that energy through a low frequency vibration in the infra-red (heat region). CO2 is one such molecule because it has a low-frequency bending vibration. H2O is another, which also has a low frequency bending vibration. The atmosphere of Venus contains almost all CO2 (I’m not sure of the exact percentage) while the atmosphere of earth contains only a small percent (approximately, less than one percent.) and a much larger fraction of H2O vapor. Thus, for earth, water vapor is approximately 23 times more effective as a greenhouse gas than CO2, given H2O’s greater concentration in the atmosphere. Should we ban emission of H2O vapor? The fact that temperature falls less on a cloudy night than on a cloudless is testament to the layperson that H2O is indeed an effective greenhouse gas. And arguments about feedback, more CO2 causing more H2O vapor, are scientific nonsense, as a first year physics relative humidity calculation would show. CH4 (methane) also has low frequency bending vibrations, and molecule for molecule, is 23 times more effective as a greenhouse gas than CO2 CH4 is contained in human and animal flatus and eructations (burps). Should we (as was attempted in New Zealand) pass a penalty tax on such emissions of CH4?
I challenge you to read some of the writings of Lindzen, Ball, Singer, Seitz and point out, on your own, without parroting from “green blogs”, the scientific errors.![]()
