The frequency at which photons are emitted or absorbed is small relative to the rate of energy redistribution among molecules and their modes, so the fraction of some molecules that are excited in some way is only slightly more or less than the characteristic fraction for that temperature (depending on whether photons absorption to generate that particular state is greater than photon emission from that state or vice versa, which depends on the brightness temperature of the incident radiation relative to the local temperature).

It is also something quite different from «AGW», i.e. the scientifically based hypothesis that the observed LW energy absorption characteristics of CO2 (and other GHGs) would lead to a significant warming in our climate system with increased concentrations of these GHGs resulting from human GHG emissions (principally CO2), which is cited as the underlying scientific basis for the «CAGW» premise of IPCC.
Proposed supporters of climate alarmism methods to combat global warming by reducing carbon dioxide emissions are not only scientifically unfounded - in the absence of extraordinary characteristics of modern climate change, but also incredibly expensive in economic terms.
