Why the CO2 mirror analogy is wrong08-01-2016 14:59 | |

A mirror reflects light back. CO2 does not. CO2 absorbs IR radiation at the 15 microns range. However, when CO2 re emits absorbed IR radiation, the range has to be at a longer wavelength of more than 15 microns. Therefore, whatever CO2 re emits, no other CO2 can re absorb, and so must go straight into space. I think this is why the CO2 trapping of the greenhouse effect theory is not correct, which assumes continuous absorption and re emission of IR radiation like a pinball machine, making it difficult for IR radiation from the ground to go into space.

CO2 has its own complete absorption signature that involves bands/ranges of frequencies. Tai Hai Chen wrote:However, when CO2 re emits absorbed IR radiation, Nothing "re-emits." What is absorbed is based on absorption signature. What is emitted is based on temperature, according to Planck's Law.

Because a CO2 molecule re emits at a longer wavelength that what it absorbs in the first place, this longer wavelength cannot be absorbed by any other CO2 molecule nor by the warmer ground. |

As I explained to you, what CO2, or any substance for that matter, absorbs is a function of its absorption signature, and what is emitted is a function of its temperature, specifically Planck's Law. [img]http://tse2.mm.bing.net/th?id=OIP.Md9bff58e34697d60942a3c30956c0740H0&pid=15.1 Ergo, it is easily possible for a substance to absorb sufficient energy at one wavelength for it to arrive at a temperature that causes it to emit at either a higher or lower wavelength according to Planck's Law. When you place a cup of water into a microwave oven, the microwaves that heat the water are of a longer wavelength than the infrared wavelengths that the water will emit when you are finished heating it. .
