One interesting fact that I like to point out (because of the efforts of others out there that attempt to politicize the issue): equations like that come as the result of work made by scientists like Gilbert Plass in the 1950’s.

Before Plass and others the consensus before the 1960’s was that yes, CO2 and other gases do warm the earth, and while the CO2 was increasing the evidence then pointed at the natural sinks of CO2 to control the issue and the absorption bands of CO2 and other gases were understood enough.
However, almost at the same time, the evidence popped up that the absorption bands were not quite right and that the natural sinks were not doing what was expected. (Cue most of the scientists then thinking: “Oh, S**T!”)
Now, getting back to Plass and the reason to point at his work, Plass and others like him were actually working to make reality and to then improve the new heat seeking missiles being developed, and what was the main reason (looking at how climate was affected was just Plass wondering if the data could be used for climate) to take a look at how heat was being absorbed in different layers of the atmosphere to make better missiles? To shoot down those commie planes during the Korean war.
To me it is an important fact to point out because, sadly, many contrarians out there do launch accusations to the ones doing climate research or the ones proposing changes as being communists, fascists or enemies of freedom. As well as to point out to the contrarians that this is not a new idea.
