I have read oodles of hand wavy qualitative text about 'the greenhouse effect' and it is clearly dominated by the absorption characteristics of H2O vapour.
What I struggle to understand is the part of CO2 in radiative absorption, in relative quantified terms.
CO2 has absorption peaks at 2.7um, 4.3um and 15um, which relate to black body radiation temperatures of 1074K, 674K and 193K, by Wien's law.
The text I have read simply says something like 'there is no simple equation to describe radiative forcing with CO2'. My question is why not, and 'roughly' what is it, not looking for a precise answer, just an empirical plot and justification?
