In view of the much larger quantities and
absorbing power of
atmospheric water vapour it was concluded that the effect of carbon dioxide was probably negligible.»
In 1928, George Simpson published a memoir on
atmospheric radiation, which assumed
water vapour was the only greenhouse gas, even though, as Richardson pointed out in a comment, there was evidence that even dry air
absorbed infrared radiation.
Most GHE is set by the first ~ 1800 ppmV
water vapour, restricting
atmospheric GHE to non self -
absorbing water side - bands, the 23 W / m ^ 2
absorbed in the atmosphere.
By shifting a higher proportion of the IR towards the
atmospheric window, less is
absorbed in the atmosphere and that has to be primarily
water vapour side - bands.
CO2 is irrelevant to
atmospheric warming — after the first 120m of traverse of LWIR through the atmosphere
water vapour absorbs the IR to extinction and there is nothing left for the CO2 bands to
absorb.
