Apologies, meant to reply sooner. If you can score a copy of Hansen, Storms of my Grandchildren, you can get the entire picture. You're on to some of the details in your comment, but what I was looking for was "black-body absorption and radiation". As quickly as possible, an absorber of light, all wavelengths from IR to near UV, heats up as it absorbs all these photons of all waveleengths. It can emit radiation as well, BUT ONLY as a function of its temperature. So, as in a classic greenhouse, all the light comes in from near IR to near UV, heats up the surfaces inside, gets absorbed by plant leaves, etc. AS it all heats up, those surfaces, and water vapor from the plants, emit radiation, but since they are at normal temperatures - say 25-65C, they can only emit radiation in the IR heat range, which cannot get back out through the greenhouse glass panels. CO2 in the atmosphere acts similarly. Hansen explains it much better! Also important, the latent heat of vaporization. Absorption spectrums of various gases... True, for the atmosphere there are additional details beyond the classic greenhouse effect, but not really difficult to understand, and Hansen puts it all together as well as anyone. Thanks for your intelligent comment! So many on social media are merely annoying.

saw it already.

No point in continuing, as one of the comments here read, "no one cares".

Unsubbed, I leave you all to your demonstrated ignorances.

Best regards.
