About time for me to post this again:
For those curious:
CO2 only absorbs infrared light aka heat in two very narrow bands of wavelengths (think “colors” of heat). In those narrow bands, CO2 is almost completely opaque.
Even at only 0.04% of our atmosphere, CO2 absorbs almost all infrared light in those bands within a few tens of meters. Hence, if you increased CO2 by even 10 times, the total amount of infrared light (again, heat) absorbed by the atmosphere would NOT CHANGE.
Think about it like this: You have 10,000 sheets of very thin semi-opaque paper. Each sheet abosbs 0.04% of light passing through it. That means those 10,000 sheets will aborb almost all of the light passing through them.
Note: the math is a little complicated. First sheet aborbs 0.04% of the light leaving 99.96% left. Next sheet abosorbs 0.04% of the remaining 99.96% leaving about 99.92%. Next sheet aborbs about 99.96% of that, leaving 99.88% left. After about 10,000 sheets, only about 1.83% of the light is left. Basically all of it has been absorbed (and likely converted into heat).
Consider those sheets to be about 1 meter thick (that is a gross overestimation — it’s probably more like 10 cm thick, but erring on the side of a conservative estimate). That means your 10,000 sheets are a combined 10km thick. The atmosphere is about 10,000km thick. Hence all infared light is abosbed in the first 1/1,000 of the atmosphere.
How much more light is absobed if you increase the opaqueness of those sheets? Answer: none.
Outside of those narrow bands, CO2 is almost completely transparent. So again, if you increased CO2 by even 10 times, the amount of infrared light (again, heat) would NOT CHANGE.
Now the climate “scientists” try to handwave and “computer model” their way around these basic physics facts. After all, computer models are always right (/sarc). But that’s how the REAL physics works.
Short version: manmade aka CO2 caused climate change is not just a hoax, it is not even a very good hoax for those who know the physics. Unfortunately the level of basic physics education in this nation is basically nil with the exception of real engineers, physicists, and scientists.
Furthermore, why does CO2 only make up 0.04% of our atmosphere? The answer is simple: CO2 is PLANT FOOD. More CO2 simply means more plants and thus more O2 (oxygen). The plants including trees, grass, and mostly plankton simply gobble it all up. “Carbon based life forms” anyone in the class?
They don't just gobble it up. Dead plankton, fish poop, and other organic material fall to the ocean floor and become another layer of sediment. Carbon is continually being removed from the atmosphere by biological processes. Those seams of coal we mine were, long ago, vegetation which got buried.
Thanks for presenting what those of us who actually have done real work in this area know about CO2. The climate porn presented daily in our media works only because media types are those who could not and never will pass the most elementary courses in chemistry, physics, and math, let alone any requiring some real analysisl. One other item I usually mention is that CO2 is presently rising from one of the lowest percentages that we know has existed, and had that percentage dropped a bit lower, plants would have gone the way of Biden’s and Rachel Maddow’s IQ.

Well done. Interesting and quite telling that here, on our rather tiny but potent forum, there is more accurate scientific analysis presented on the CO2/climate issue than is coming from the vaunted institution of UC San Diego.
Sad that most of our universities have become cesspitts of propaganda.
