I will admit that I'm not knowledgeable enough to explain the advance physics of it, but here is a page that should.
Greenhouse Effect: Background Material
"Greenhouse Gases
Carbon dioxide () is one of the greenhouse gases. It consists of one carbon atom with an oxygen atom bonded to each side. When its atoms are bonded tightly together, the carbon dioxide molecule can absorb infrared radiation and the molecule starts to vibrate.
Beginning with an assumption. That doesn't bode well for a link that purports to be engaged in physics. There is no such thing as a greenhouse gas as described by alarmists. The only gas that acan absorb, and actually retain energy is water vapor.
Eventually, the vibrating molecule will emit the radiation again, and it will likely be absorbed by yet another greenhouse gas molecule.
Eventually? Eventually? Are they kidding? Energy passes through the molecule at, or very near the speed of light. Explain the use of the word eventually by these people when IR passes through a molecule at the speed of light? How long do you think it takes for a packet of energy to pass through at the speed of light? Eventually? I am laughing Matthew and you should be also. Eventually.
Then there is the matter of the energy being absorbed by another "greenhouse gas" molecule. We have already been through that. It doesn't happen. The energy is emitted from the molecule in a wavelength that is to long to be absorbed by another. If you repeat things you know to be untrue, even if it is via cut and paste, you are being used as a tool. Is that what you want?

Clip:
What happens after the GHG molecules absorb infrared radiation? The hot molecules release their energy, usually at lower energy (longer wavelength) radiation than the energy previously absorbed. The molecules cannot absorb energy emitted by other molecules of their own kind. Methane molecules, for example, cannot absorb radiation emitted by other methane molecules. This constraint limits how often GHG molecules can absorb emitted infrared radiation. Frequency of absorption also depends on how long the hot GHG molecules take to emit or otherwise release the excess energy.
This absorption-emission-absorption cycle serves to keep the heat near the surface, effectively insulating the surface from the cold of space."
First, that absorption emission cycle as described simply isn't happening. Second, how long do you think it might take for a packet of energy to radiate into space through the atmosphere? How about 0.0049 seconds? Want to see the math? It's peer reviewed by the physics department of a university. I could't find any problem in the guy's math or any hint of a misplaced physical law. The guy walks step by step through some relatively complicated calculations and works from the foundations of physics. It is worth a look if you have any interest at all in the truth.

The ability of certain trace gases to be relatively transparent to incoming visible light from the sun, yet opaque to the energy radiated from the earth is one of the best understood processes in the atmospheric sciences. This phenomenon, the greenhouse effect, is what makes the earth habitable for life."
Opaque. Warmist keep using that term and it carries with it certain connotations. Lets look at the word for a moment if you don't mind. Here are some various definitions I found for the word including some from scientific sources.
opaque - not transparent or translucent; impenetrable to light; not allowing light to pass through.
opaque - not transmitting radiation, sound, heat, etc.
opaque - Resistant to the transmission of certain kinds of radiation, usually light. Metals and many minerals are opaque to light, while being transparent to radio waves and neutrinos
opaque - Impenetrable by a form of radiant energy other than visible light
I have to say Matthew that the known properties of CO2 are in no way opaque to visible light or IR. The word opaque is misleading if not down right dishonest. The claim that the property of CO2 to be transparent to visible light and opaque to IR radiated by the earth being one of the "best understood processes in the atmospheric sciences." is a deliberate lie. IR radiates through CO2 at or near the speed of light. The emission spectra of CO2 proves this fact. CO2 is in no way opaque to any form of energy. It absorbs and emits but is not opaque.
Tell me Matthew, did that fact even pass through your brain? Even the warmist kooks acknowledge that CO2 passes right through CO2 even though they wrongly claim that some of it gets emitted down towards the earth in defiance of wave vector calculus. When you look at that sort of stuff, do you think critcally about what it is saying or do you just look for something that might support your point?
The claim of opaqueness isn't even complicated Matthew. It is a deliberate lie and should clue you into the validity of the rest of the claims made.
If this is not so then science is out right fucked. If millions of people can't even trust to learn the science from a major university science deportment how the hell do you expect any better?
You know it isn't so, don't you? You don't need to be a physicist or chemist to grasp the fact that no material that is opaque to any form of radiant energy can have an emission spectra. How could it? If a material is opaque, nothing comes through. The fact that CO2 has an emission spectra is clear evidence that it is not opaque to visible light or infrared.
And how do I expect any better? As I have already suggested, make yourself familiar with the basic laws of physics. The math involved is predominantly algebra or lower and can be fairly easily self taught if you have a will to learn it. I suggest getting a physics for dummies sort of text that doesn't assume that you know anything. They take you through the basics and show you the calculations step by step and give you problems to solve on your own.
Do I really expect that many people actually make the effort to learn any of this to a degree which they can determine for themselves whether they are being taken for a dupe or not? No, not really. Most people in this (scientists included) base their positions on political ideology and not whether the science is sound. Climate science has corrupted the image of science to a greater degree than any other science I can think of in the history of man all for political ideology.
Here is what I consider a pretty good write up and has some good reasoning on the science.
Has the greenhouse effect been falsified?
Again, a great many assumptions, appeals to authority and appeals to complexity. As I said, I don't go to that site because the moderators censor anyone who is effectively defeating the party line.
I believe that many of these are people that are fairly educated in the sciences and if they don't know then our understanding is very limited. It is so limited that it is scary.
Yeah well, education doesn't necessarily mean anything does it. The people who told you that CO2 was opaque to IR and that was the principle upon which the greenhouse effect operates were supposedly educated weren't they? Education is a great tool to use in a debate in which you have a political point to make. An educated person can double talk and appeal to complexity at a much higher level than joe blow.
