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.
Global warming means increasing life and abundance. Global cooling means decreasing life and abundance. Where we are in the cycle is indeterminate. Man does not control nature nor the mechanisms of climate.
He is more likely to kill himself off with his silly wars, drug poisonings, excessive environmental destruction and unhealthy lifestyles. If the earth is gonna melt, it will be the result of the way of the universe.
How does the greenhouse effect work? I don't understand all the physics involved. But my very crude understanding goes something like this. As CO2 increases, the lower atmosphere warms but the stratosphere cools. The stratosphere also expands a bit outward, toward outer space, as a result of the extra CO2. This means that the new surface layer where heat finally escapes to outer space is a bit colder than the old surface layer. To achieve the desired outflow of energy, so as to equal the inflow from the sun, the earth must warm in order to get the new surface layer back to the proper exit temperature.
Regardless of the degree to which anyone detests the object of criticism, an "appeal to detestability" is the ad hominem fallacy.
To call such an appeal an unhelpful distraction is to restate the obvious. Regardless of what conclusion a person reaches, it's quite likely influenced by another fallacy; the appeal to emotion.
Any form of argumentation that includes elicitation of emotion will devolve into irrationality, particularly so when the desired emotion is fear.

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.

I suspect you have read this somewhere. Can you supply a reference or link?

Am I close?

Can someone tell me what the CO2 level was during the time of the dinosaurs?
