Are you working at being stupid? The absorbtion spectra of CO2 was defined by Tyndal in 1858.
In a closed controlled environment, not a dynamic one.
This very relevant detail has been pointed out to you uncounted times, but since it contravenes your warmist religion it just bounces off your pointy little head.
OK, I apologize. I did not realize the depths of your ignorance.
The absorbtion spectra of a gas does not change, whether it is in a tube, a box, or the open atmosphere.
I can plainly see that you have not even had high school physics or chemistry.
Why here's an interesting little article for you Old Rocks:
Explanations of the CO2 Absorption Spectrum.
CO2 Absorption Spectrum
There is no Valid Mechanism for CO2 Creating Global Warming
Proof one:
Laboratory measurements show that carbon dioxide absorbs to extinction at its main peak in 10 meters under atmospheric conditions.* This means there is no radiation left at the peak frequencies after 10 meters. If then there is a doubling of CO2 in the atmosphere, the distance of absorption reduces to half, or 5m. A reduction in distance is not an increase in temperature. Convectional currents stir the heat around removing any relevance for distance.
Scientists who promote the global warming hype try to work around this fact by claiming something different happens higher in the atmosphere, which they claim involves unsaturation on the shoulders of the absorption peaks. (See Disputed Zone.) The difference due to height is that the absorption peaks get smaller and sharper, so they separate from each other. Near the earth's surface, the absorption peaks for water vapor partially overlap the absorption peaks for CO2, while there is less water vapor high in the atmosphere. Supposedly, separating the peaks creates global warming. There is no credibility to that claim.
It is nothing but an attempt to salvage global warming propaganda through fake rationalizing of complexities.
What it means is that climatologists admit there is no mechanism at lower levels of the atmosphere, and their rationalization for higher up is phony.
It's important to realize that radiation from the sun does not greatly heat the atmosphere, because the sun must give off high frequency radiation in the area of visible light, which goes through the atmosphere. Something as hot as the sun cannot give off low frequency radiation. Temperature determines frequency. This means that most of the sun's radiation heats the surface of the earth, and then the heat moves from the earth's surface into the atmosphere through conduction, convection, evaporation and infrared radiation. The infrared radiation can be absorbed by so-called greenhouse gasses.
Heat leaves the planet through long wave infrared radiation.
Absorption Peaks
Carbon dioxide absorbs infrared radiation (IR) in three narrow bands of wavelengths, which are 2.7, 4.3 and 15 micrometers (µM). This means that most of the heat producing radiation escapes it. About 8% of the available black body radiation is picked up by these "fingerprint" frequencies of CO2.
Several decades ago, before global warming was an issue, scientists concluded that carbon dioxide blocked 8% of the infrared radiation from going through the atmosphere. This is consistent with bandwidth. The width of the 15 micron peak is two microns wide from outer edges of shoulders. The total range of infrared radiation is about 100 microns, tapering off after 50 microns.
A measured absorption spectrum is shown here. See an exactly measured 15 micron peak in Heinz Hug's paper.
Heinz Hug* showed that carbon dioxide in the air absorbs to extinction at its 15µM peak in about ten meters. This means that CO2 does whatever it's going to do in that amount of space. Twice as much CO2 would do the same thing in about 5m. There's no significant difference between 5m and 10m for global warming, because convectional currents mix the air in such short distances.
Attempted Fix
This is nothing new.
Climate scientists know that more CO2 does not result in more heat under usual conditions. So the mythologists among them try to salvage the global warming propaganda by pretending that something esoteric occurs higher in the atmosphere. The difference is that the absorption peaks for CO2 separate from the peaks for water vapor. Then supposedly, radiation which misses CO2 does not get picked up by water vapor and travels into outer space; and more CO2 causes less radiation to get missed on the shoulders of the peaks.
Everything about that rationalization stretches reality to a point of misrepresentation. The increase in CO2 levels could only be relevant for the last cycle of absorption near the outer edges of the atmosphere, where there is not enough influence of the lower atmosphere to be significant. But the rationalizers claim it is significant in the mid levels of atmosphere. Not so. Doubling the CO2 would only shorten the distance of radiation travel before total absorption occurs.
The outer edges of the shoulders of the absorption peaks are said to be unsaturated, because they don't absorb all radiation available to them. The unsaturated area is virtually nonexistent. The image at right shows how the distance of absorption increases as shoulder molecules get thinner. Where the molecules are one tenth the density, the distance is ten times as much, which is 100 meters. Where the density of one hundredth, the distance is 1,000 meters. Where is the unsaturation supposed to be? Fake equations are contrived to show a result in contradiction to the obvious logic.
Thanks for playing though.
