For example, the first row describes
a uniform warming of the atmosphere, which increases the cooling to space by 2.3 W m2, but also increases downward emission to the surface by 3.3 W m2.
It also seems that even though the selective absorption
of specific energy bands by different molecules IS the mechanism to add energy to the air, the energy absorbed by CO2 & especially Water Vapor is extremely rapidly dispersed by molecular collisions to ALL the components
of the
atmosphere, so that the N2 and O2 also heatup, and all the atmospheric components assume a
uniform temperature (ie global
warming).
