That equation was conjured up. Now, Geran stated: “Study established physics, especially including heat transfer, thermodynamics, and quantum physics.” Now, the most critical is the new phenomena of quantum physics. I don’t make the same mistake. Fluxes don’t add and energy only flows from higher energy to lower. This mode depends on the energy of the photon absorbed which must be in one of a limited number of energy levels due to there being a limited number of geometrical vibrational modes available. You are making the same mistake as many others by relating the wavelength to a precise temperature which cannot be applied to the release of internal energy. This seems to be the resort of all those who object to luke-warmers but they all generally come down to some (deliberate?) Thus the only absorption and re-emission by atmospheric CO2 of any consequence must be the photons in the 15 micron band. The CO2 laser is actually somewhere between a maser and a laser so for convenience sake everybody calls it a laser, I’m surprised you didn’t know that. I was just having this conversation with Geran the other night and promised him a quick quiz that never materialised. m. of which the 15 micron band dominates with 99.83% of the total. https://en.wikipedia.org/wiki/Carbon_dioxide_laser, “The population inversion in the laser is achieved by the following sequence: electron impact excites the {v1(1)} vibrational mode quantum state of the nitrogen. You are proving me right, again. Please do the experiment before posting an answer. If you believe 10um IR can have no warming effect you could try putting your hand in way of a beam from water cooledCO2 laser emitting that wavelength to prove it but please don’t. You are lost in your pseudoscience. Principia Scientific International (PSI) is a not-for-profit community interest association. That is why I would be classed as a luke-warmist because I accept that such does not contravene any laws of physics and will happen. I do know how CO2 lasers operate but some people do not really appreciate just how warming 10um IR can be unless considered at high intensity. I’m willing to change my position, I just need to see some evidence that demonstrates it. The 10um emission from CO2 comes from the reduction of the internal energy of the molecule and cannot therefore be related to temperature (as per visible light wavelengths emitted in chemo-luminescence or gamma radiation in the decay of the Co-60 nucleus). Geran: 1.995 to 2.036 microns. And the level of mathematics required for quantum physics goes beyond calculus. 0 votes . Low-lying infrared absorption bands of CO2. The source temperatures that radiate at the CO2 absorption peaks are:a. Low temperature photons can’t raise the temperature of a higher temperature object. And there was no model of an atom which explained how it was that atoms had a geometric structure until Erwin Schrodinger, a physicist, assumed that the electron of the simplest atom (hydrogen–a proton and a electron) and applied the mathematics of radiation to this simple model and discovered that the hydrogen atom had geometry. When will this sick evil IPCC hoax die? Since 99.83% of the photons that may be absorbed by the atmospheric CO2 molecules will be from the 15 micron absorption band and these represent radiation from a source at 193.5̊K, they will not heat the Earth’s at its average surface temperature of 288.5̊K. 1 Answer +1 vote . I would have to take you to task on one phrase.. It is found that independently from the vibrational state of the molecule the frequency separation between the rotational lines for both P- and R-transitions is constant and about 50 GHz. It follows that no matter what the intensity absorption of IR, no matter what the wavelength, has a warming tendency. If there was a Greenhouse Effect they would stand in random directions receiving the Greenhouse radiation on their backs. 4.189 to 4.377 microns,c. The purpose behind co2 in the laser is to remove heat from the light source so that it doesn’t over heat. Just 2 observations about CO2 lasers — TL. This ability to absorb and re-emit infrared radiation is the critical requirement for greenhouse gases. A laser gets its power because of harmonics where there is no interference between the light waves and there power/amplitude combine, which doesn’t happen in natural light. Abstract: The present study describes the absorption of thermal emission from the earth surface by CO2 in the atmosphere. Something about cold carbon dioxide raising the temperature of warm Earth. The effect of the absorption and re-emission of the Earth’s radiation at this rate of photons must be completely insignificant as is the current rate of increase in CO2 of 3.4 ppm per annum. The CO2 molecule has strong infrared absorption bands that belong to the symmetric stretching vibration v1, the degenerated bending vibration v2 and the asymmetric stretching vibration v3. Something you have yet to learn. PRINCIPIA SCIENTIFIC INTERNATIONAL is legally registered in the UK as a company incorporated for charitable purposes. It seems that perhaps you too can be classed as a luke-warmer until you assess the magnitudes and effects of the processes in the manner which proper science demands. They fail to reveal to the reader that infrared radiation forms 52% of the Sun’s emitted radiation. The absorption of thermal emission from the earth by CO2 occurs at wavelengths around 15, 5 and 4.3 microns. So far no such experiment exists. The fraction of the molecules for j = 16 is as indicated 0.078. In order to discover this, one of the items would have to be timed for cooling, then the manner that you described. GRAVISPHERES: What’s the matter with Dark Matter? Water vapor and carbon dioxide can absorb radiation wavelengths in the range of 4 μm to 80 μm, except those between 8 μm and 12 μm. The analysis is performed assuming 400 ppm CO2 in the atmosphere for which we found saturation of absorption. This gave the absorption band limits to be:a. 2.663 to 2.823 microns, andd. CO2 absorption in the 12-18um band, with terrestrial spectrum overlaid. Herb. environmental chemistry; class-11; Share It On Facebook Twitter Email. 1 Answer. Further, it stated that “Especially the absorbed radiation power by the ground state bending mode at about 15 microns is dominant.” The Conclusion states “The absorption of thermal emission from the earth by CO2 occurs at wavelengths around 15, 5 and 4.3 microns.”. Actually, they want you to believe way way more, particularly that CO2 reemits it and the Earth’s surface absorbs it, raising its temperature on a global basis that requires them to take over the world to stop it. And yet again no one who believes in ghe shows anything that proves ghe. These natural carbon sinks – oceans, plants and soils – help to buffer the continued emissions from human activity. Something has to be demonstrated in order to prove that a hotter object is absorbing energy from a colder object. A CO2 laser is a manmade device. incoming, absorbed energy is short-wave radiation and the emitted energy is long-wave radiation. Stand in the shade with an open view of the sky above and you will not feel any warmth arriving from the sky above, just the local ambient temperature everywhere. If neighbouring conduct heat away they themselves must be heated in turn. -79.5̊C, occur occasionally in Antarctica and the surface there is too cold to produce any significant radiation in the three shorter wavelength absorption bands. The SB law says that the energy density is found between an object and its colder environment. Portions copyright © Principia Scientific International I stop here to allow you to possibly tell me: ‘I already knew that from my high school chemistry and physics classes.’. Physics and Chemistry are the two fundamental physical sciences. 13.26 to 17.07 microns,b. James McGinn / Genius PRINCIPIA SCIENTIFIC INTERNATIONAL, legally registered in the UK as a company incorporated for charitable purposes. Furthermore, it is found that practically about 90{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of the frequency space between the rotational lines of the absorbing vibrational bands around 15-, 5- and 4.3-micron wavelength contributes relatively little to the thermal absorption. [The Earth’s surface] “which will always be held to the same temperature as the surroundings by conduction from the surrounding molecules, making global warming impossible” TL. The laws of thermodynamics mandate that heat cannot flow from cold to hot so the return of some radiation back towards the Earth cannot cause surface heating as it is only a fraction of the energy being emitted from the surface. d.      wavenumber 4989.97 cm^-1 ,that is, wavelength 2.00402 microns,frequency 149.6 Tera Hz, amplitude 1.356 x 10^-21 cm/mol. 412̊C,c. misinterpretation of what is being described. m.. for a total photon density of 6.9603 x 10^+13 photons per cu. It will bounce off most other materials, and a few will pass it through, like glass. Too bad, atmospheric CO2’s Planck radiation isn’t collimated and is all at 15 microns, and any that strikes Earth’s surface will bounce off or be absorbed by the surface molecules, which will always be held to the same temperature as the surroundings by conduction from the surrounding molecules, making global warming impossible. Carbon dioxide absorbs infrared radiation (IR) in three narrow bands of wavelengths, which are 2.7, 4.3 and 15 micrometers (µM). If it can’t raise the temperature it can’t raise the temperature. 1] provides a detailed account of the absorption of thermal emission from the Earth surface by atmospheric CO2. Roughly less than 10{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of the infrared flux that falls within the absorption bands of CO2 will be absorbed. Written by W.J.Witteman, Emeritus professor University of Twente (NL). No matter what happens to it, 15 microns isn’t even in the normal weather range, it’s dry ice temperature, and for the IPCC hoaxers to want to take over the world to stop CO2 emissions is a sick hoax designed to fool suckers. The molecule gains kinetic energy by this absorption of IR radiation. When visible light and high frequency infrared radiation are absorbed by the surface of the Earth, the planet’s internal energy increases and the surface gets hotter. m.. c.      energy density 7.5175 x 10^-8 J/cu.m., being 4.139 x 10^-3 of the total emission and a photon density of 1.0154 x 10^+12 photons per cu. about 300 m. The fraction for j =2 is 0.02 so that also these molecules saturate the thermal emission flux within about 200 m. Thus, between j = 2 and j = 40 about 98{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of all CO2 molecules in the considered band absorb all the emitted infrared radiation that falls within their spectra within a distance of about 300 m and in the case of 200 ppm it is 600 m. The same result will be obtained by considering the R- branch. So, chemists, via experimental results involving simple molecules like carbon dioxide and water and other molecules that the atoms of matter had to have a geometric ‘structure’. which radiation are absorbed by CO2 ? From inspection of the HITRAN listing, the absorption bands were chosen by taking 1000th of the peak line intensity as their outer limits. Spectroscopy is a subject nobody cares about except when there’s a good punchline, such as with lasers. How many ways can you flog a dead horse? Chris. Even the emitted wavelengths can be adjusted. This has nothing to do with natural uncollimated Planck radiation absorption/emission at 15 microns. CO2 does NOT warm the surface.

Maybee I do not understand you paper fully, but to me it looks as if you calculate the absorption length for different absorption bands, but how do you reach the conclusion about 10%? The Earth's atmosphere reflects, absorbs and scatters No experiments demonstrate that fluxes add. They are 1800 K, 950 K and 3370 K for respectively the v1, v2 and v3 vibrations.

My apologies for my apparent rudeness I am so used to responding to the likes of Squidly, Geran and Geraint who like to put up a good show of knowing all about global warming but the way they avoid scientific discussion makes me think otherwise. https://anchor.fm/james-mcginn/episodes/What-Causes-Streaming-in-the-Atmosphere-eai2jq. This number decreases according to eq. What Causes Streaming in the Atmosphere? A laser has NOTHING to do with the GHE. Especially the absorbed radiation power by the ground state bending mode at about 15 microns is dominant. Roughly, only 10{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of its spectrum is active and the thermal radiation that falls within these regions is fully absorbed. That demonstrates how little you know. The actions require both “design” and “external energy”. You would need to determine the total rate of energy transferred by back-radiation then determine what happens to that energy it cannot just magically disappear and, like it or not some of it will be absorbed by the Earth’s surface. Hopefully, you learned in these two courses that physicists study physical phenomena and attempt to understand (explain) these physical phenomena and chemists study matter, using the physicists physical phenomena to understand (explain) matter and the changes it (matter) undergoes. Telephone: Calls from within the UK: 020 7419 5027. International dialling: (44) 20 7419 5027. Is Sustainable Energy Even Possible Globally? I see no problem GHE in itself only with the supposed magnitude of the effect, along with associated forcings, unscientifically claimed and certainly not proven by alarmists. Feel the temperature of objects in the shade. I got my data here. Share with your friends. https://en.wikipedia.org/wiki/Microwave_oven However, radiation back into space from the shorter wavelength CO2 absorption band, emitted from the Sun, should have caused the Earth’s temperature to decrease as the CO2 concentration increased. Iain Stewart demonstrates a simple experiment that shows that carbon dioxide absorbs infrared radiation. “any that strikes Earth’s surface will bounce off or be absorbed by the surface molecules, which will always be held to the same temperature as the surroundings by conduction from the surrounding molecules, making global warming impossible” The key phrase is “or be absorbed by the surface” that is the essence of the GHE some of the emitted energy will be re-absorbed and any absorption must exert a warming effect. In 1970, NASA launched the IRIS satellite that measured infrared spectra between 400 cm-1 to 1600 cm-1. The net result is that increasing absorption of long wave radiation by CO2 is MUCH smaller than increases in surface temperature. That is, doubling the amount of $\ce{CO2}$ does not mean doubling the amount of IR radiation absorbed and redirected back towards earth. In short, by expending a lot of energy a population inversion can be created in CO2 that lases from higher levels at 10.6 and 9.4 microns, and can be amplified in a cavity to create a narrow collimated beam of high power. As there is no warming to be detected from the sky above, there no reason to accept the UN IPCC thesis of a Greenhouse Effect. But the elephant in the room is the U.N. IPCC and its giant Hoover machine sucking billions and threatening our freedoms and comfort in an effort to destroy the fossil fuel industry because its CO2 emissions are supposedly so evil. That being said I first came across one of the strange properties of H20 in 1959 when I was a radar technician working on a piece of equipment ‘Cloud and Collision Warning’ by E K Cole as used in Comet II aircraft so they could avoid turbulent air and it was extraordinarily effective.
