  • CO2 and water vapour

    Thanks for this web site that I just recently got to know about. I have three questions:

    1. Some one mentioned that water vapor traps unequally different wave lengths of radiation. Also, that trapping would easily get saturated in those wave lengths it traps. a) Is this important for forcing? b) Does it mean that forcing is rather independent of amount of water vapor in the atmosphere? c) How does CO2 behave w/ respect to the same phenomenon?

    2. I encountered a claim that the trapping of radiation that CO2 does, takes place in the first 10 meters above ground. So, if you double CO2 concentration, the same trapping takes place in 5 meters. Therefore, there is no increase in RF with an increase of CO2 concentration. Is it so?

    3. People seem to use computer models to compute RF's of different concentrations. Why not set up chambers and simply measure radiation penetration at different concentrations?
    On Water vapor is indeed a powerful greenhouse gas, but there is plenty of room for CO2 to play a role posted 1 year, 10 months ago 29 Responses
