The only real test to find out, would be to either continue adding CO2, and see if we all actually die in a few hundred years, by the prophesied 2 C rise in average global temperature, since the industrial revolution. Or, we can scrap everything we've accomplished, spend lots of money, exhaust our resources, trying to rebuild the world, enjoying all the hardships, starvation, and so on, by removing as much CO2 as we can. Personally, I like adding more CO2, and see how it turns out. Plants are going to use more CO2, as the do a lot better with more food. The other part of photosynthesis is sun's energy. That's less CO2, and less solar energy to warm the planet right there naturally. And as a bonus, we get more food, cheaper and easier to produce, building materials, fibers for clothes, rope, paper, and many other things. We can see actual benefits of more CO2, it's guaranteed. We can't be 100% sure any warming actually exists, or CO2 is the key. From the Al Gore movie timeline, we have already passed the point-of-no-return, and the science was declared 'settled', set in stone. If it was a lie back then, then they are lying now, giving us more time to get in on the wonderful 'green' new world, they want to create for us. Nature will make it actually green for us, if we let it. Let's face it, 2030 ain't happening, 2050 goal, unrealistic, and a little painful, and unlikely. The world is just too unsettled, no large scale cooperation on anything. No one is going to give up air travel, or large boats, high dependency, and many rely heavily on them as machines of war. We've been successful as a species, by moving forward, building on what we've learn and created, not tearing it all down, and starting over. |

VernerHornung wrote: While it's true the Earth and its atmosphere radiate together toward space, the components—surface, and each layer of air at its own temperature and pressure–must be analyzed separately as each interacts with the other components.

Incorrect. If you want to know the temperature at a point on the surface, you use a thermometer. You should learn the difference between a temperature at a point on the surface of the earth (of which there are bajillions) and the average global temperature (of which there is only one). You will remain utterly confused until you get that sorted out in your mind. In order to one day arrive at the average global temperature you will need the earth's emissivity, which no one has at the moment.

A global warming scenario might raise temperatures aloft without raising them very much at the surface when convection and latent heat are involved. Can you say "violation of thermodynamics"? It really doesn't matter how you slice it, your scenario here violates physics in some way, depending on how you are defining your scenario. Anyway, you can't just raise the temperature of just one part of the atmosphere while leaving everything else the same. Stop trying to subdivide the body and you won't create so many errors. If I turn on my oven so it can "pre-heat" ... what areas inside actually decrease in temperature? What areas inside simply don't increase in temperature while others do?

tmiddles wrote: From what I understand, diatomic molecules aren't good infrared absorbers/emitters. For IR, the molecule needs a third atom in the middle that wiggles back and forth to produce changes in the molecule's dipole moment. Almost like radio transmitter antennas, except at much higher frequency. See properties of a greenhouse gas Amer. Chem. Soc. https://www.acs.org/content/acs/en/climatescience/greenhousegases/properties.html Nitrogen will emit thermally because of its temperature, but only by inelastic collisions between the molecules. Radiation phenomena do care what's radiating, and the ground, radiating mostly around wave number 1000, won't transmit much energy to N2 by radiation. What happens with the N2 is this:  The N2 takes some heat from the ground by conduction, expands and rises (convection), and finally radiates at altitude. But it can't receive and re-emit rays from the ground at WNs near 1000. And the ground emits very little at wavenumbers the N2 does absorb, which are in microwaves and extreme ultraviolet, I think. So the N2 is just radiating what it got from the ground by conduction. What happens with the CO2 is this:  Same thing again. Heat from ground by conduction, rises, radiates this conducted heat. But it's absorbing rays at WNs near 1000 as well, additional energy the nitrogen wasn't getting. It re-emits this as well. (CO2's big spectral line is actually centered on WN 667, but that's close enough, still within the ground's strong emitting range.) Now the difference between these scenarios and an airless Earth: You're right. The N2 delays radiation of energy from the ground to space, yet it also delays the sun's warming of the ground by carrying much heat aloft in convection. (Think thermals on a hot day.) So there's really no net delay at all, only moderation, a lessening of the contrast between day and night. N2 won't work as a greenhouse gas on Earth. Yet again, the pressure the N2 and O2 exert on the CO2 and H2O broaden the latter's spectral lines and "boosts" their greenhouse effects. Complications what makes radiative transfer theory in planetary science so hard for me to understand. The way a gas behaves, greenhouse-wise, will depend on temperature and pressure. Venus is only twice as hot as we are, 730K versus 288, and it has tons of CO2 to make up for the loss of greenhouse efficiency involved. I've pushed it to the limit for me, though. I'm not a "radiation guy" and none too spectral. ~ tmiddles wrote: The absorption part was repeated in that YouTube ditty. The CO2 bottle got warmer than the air bottle did. Bottles of N2 or O2 would act similar to the air bottle. You can't heat those gases with a restaurant heat lamp. (Nuclear bombs heat them with X-rays to make a fireball.) tmiddles wrote: Yeah, does little for Venera, which probably looks like a blackened rock you pull out of your campfire by now. But the CO2 ice is 50 miles up in the air there. There's little convection near the surface; it's stagnant. Cold air on Earth is close by. Planes need a heater before they need to be pressurized. And cold air helps speed convection, which I believe tends to shift "global warming" toward the poles. The Arctic ends up 10˚C warmer while the temps at the equator may hardly change. IBdaMann wrote: As tmiddles noted, the term geophysicists use is "radiative transfer theory." Radiative forcing, a newer term, was introduced by climatologists to express the radiative power equivalent—in W/m^2—of various perturbations in the climate system so they're easier to compare with one another. Sorry, IBdaMann, but you're not the man in this area of study and it's not a religious dogma. IPCC gave a careful definition: "RF is the net change in the energy balance of the Earth system due to some imposed perturbation. It is usually expressed in watts per square meter averaged over a particular period of time and quantifes the energy imbalance that occurs when the imposed change takes place." —Anthropogenic and Natural Radiative Forcing, Climate Change 2013: The Physical Science Basis, p. 664. This of course applies to systems exchanging radiation with an environment but not at thermal equilibrium with that environment. Note the words "energy imbalance." Thing is, you're spewing one-liners at someone who harbors real doubts concerning the level of reliance policymakers should invest in IPCC's assessment reports and related materials produced by academic facilities. Especially if they're gonna rely on this stuff as filtered for them by panicky climate change lobbies as AOC in Congress relishes. The science itself is conservative, under review by hundreds of people in that field. IPCC had to get an international consensus for everything it published. The issues I see have more to do with the projections, as I suspect climate may be less predictable than we suppose. IBdaMann wrote: No, all the energy's still there. The diagram shows power, not energy, anyway. I'll leave balancing it an exercise for you. (Hint: incoming = outgoing at equilibrium, incoming > outgoing if warming.) IBdaMann wrote: I don't use that diagram by itself. See for instance the paper I've cited twice while you kept breezing by it as if it weren't on the board: Infrared Radiation & Planetary Temperature Raymond Pierrehumbert Department of Geophysical Sciences University of Chicago https://geosci.uchicago.edu/~rtp1/papers/PhysTodayRT2011.pdf This has our lovely term "radiative transfer theory." It does not have the word "forcing" at all. And Pierrehumbert does not work for a warmazombie climate institute of any kind. He teaches physics at the University of Oxford now. IBdaMann wrote: There are indeed. The Earth is not a blackbody. It's not even a grey body you can treat using Stefan-Boltzmann with an emissivity constant. It's more like a grey body with a partially transparent shell around it, and this shell must radiate at its own temperature. The outgoing rays from this shell, plus the fraction of the rays from the surface which pass through the shell, then become what balances the incoming from the sun. IBdaMann wrote: You can download one of them here: http://www.cesm.ucar.edu/models/ IBdaMann wrote: I'm not raising the temperature of one part of the atmosphere while leaving everything else the same.

The issues I see have more to do with the projections, as I suspect climate may be less predictable than we suppose. You think? I read in a few places around the internet, that 'climate' is defined as weather. over long periods of time... I don't particularly buy that, it might be similar to weather, but it's something different, more an environmental observation. Weather changes frequently, which can last minutes, hours, days, or even much longer, but there is sort of a 'normal', that a location will return to, if there are no weather events. I can't really see how a global average climate really applies to anything. To many areas around the world, that never experience anywhere near similar climates, ever. That global average would never apply to all areas. Weather isn't very predictable at all, maybe a day or two, with reasonable confidence, but still fails often enough. We've been trying to understand, and predict weather, well... Long before we burned fossil fuels, and still haven't gotten it nailed down yet. We've even tried many times to influence and control weather. Rainmaking has a rich history, though we don't seem to have much interest in pursuing that any more. I really find it insane, that we can only make reasonable predictions about weather, a couple days in advance, mostly a coin toss beyond. Yet, the IPCC is 100% sure about the weather/climate, decades in advance. |

HarveyH55 wrote: And climate isn't predictable, either. That's why I have some doubts about all those models. It is more consistent than daily weather; if there's a change it will be much smaller and occur over a longer period of time. The only thing the models shows is given current knowledge of climate, it's more likely that most places on Earth will have warmer average temps in 2100 than have colder temps then. The predictions run between ½˚ and 9˚F warmer for the globe, according to IPCC Synthesis Report, 2014 (see p. 10) https://www.ipcc.ch/site/assets/uploads/2018/02/SYR_AR5_FINAL_full.pdf Since 2007, there's been a shift of topic emphasis from prediction to observation of recent changes. That's why you keep hearing how this year is the hottest on record and so on. But the amount CO2 people have sent up the flue is remarkable, apparently 2 trillion tons since 1750, most of this in the last 50 years (p. 3 in same report). That would make one hell of an Alka-Seltzer fizz. Never try to solve an NP-complete problem on your own with pencil & paper. |

It would be nicer to show the photons zipping up from the surface, banging into molecules, vanishing in process, and then the atmospheric radiation coming out. The charts do sort of give an impression of energy being created over at the right edge. But the energy for the rays going up and down out of the atmosphere are powered by energy the air gets from the ground by conduction and radiation, plus whatever the air absorbs directly from the sun. My last post mentioned the collisional continuum. This is energy of molecules knocking one another about in a gas, and some of this energy appears as radiation from the air. But the mechanism differs from spectral absorption and re-emission as seen with H2O and CO2. On Earth, the continuum absorbs few rays from the ground; instead it broadens the spectral lines of H2O and CO2. Titan, the big moon of Saturn with N2 in its atmosphere, is cold enough that the surface emits mostly microwaves. These can be blocked by N2, which has microwave bands in its spectrum, so N2 acts directly as a greenhouse gas there, making Titan's surface warmer than if it were airless. On Earth, N2 and O2 act indirectly, by providing pressure to broaden CO2 and H2O lines. At least that's what I think. Mie scattering of light in a dense atmosphere also makes it more likely that a photon passing through it will encounter a greenhouse molecule. (Its zig-zag path length through the air is longer.) Dust in the air causes Mie scattering of infrared. To tell you the truth, the topic's advanced. The NASA paper in my last post describes radiative transfer theory. Work on this started with spectroscopy in the 19th century, when astronomers wanted to understand how the air affected infrared spectra of stars and planets, which arrive here distorted or missing wavelength bands altogether. The theory was also used by Eddington, Chandrasekhar and others to understand how energy propagates from the core of a star to its surface. It was never a dogma for whatever "church" IBdaMann is attacking. Application to keeping the Earth warm goes back a long ways, too, but climate change wasn't political in 1896. tmiddles wrote: I really dunno. It would make things a lot simpler if he's right. There's a limit to how far light penetrates an absorbing gas, however. You can heat CO2 in a plastic bottle with a heat lamp; the gas in the bottle is thick enough to absorb most of the lamp's rays. It seems to that very little light of infrared wavelengths CO2 absorbs should even make it down to the 200-millibar level on Venus. And visible light doesn't heat small-molecule gases like N2, O2, H2O or CO2 by much.  Notice the thermocline on Venus. Temps drop as you go up, but above a certain level, the temps rise with altitude. This is the stratosphere. If simple density of air determines temp, this shouldn't happen. Huffman's honest enough to admit he doesn't know why planets have stratospheres. Finally, the drop at low altitudes means heating from below. Even with Venus's sluggish convection, hot air does rise there. Huffman's coincidence is striking. I don't believe mainstream science is incompetent. If it were, we wouldn't have the high-tech society we enjoy. But it's always possible science is wrong despite consensus. We had the "four humors" theory of disease from Greek times all the way up to Koch's discovery of anthrax bacteria in 1876. They rewrote Big Bang cosmology to have an accelerating expansion not seen in earlier versions of it. The heating of planets by stars may simply not work the way NCAR and Tyndall think it does. tmiddles wrote: It's a Circus Maximus nowadays. When we had the Yellowstone fires in 1988 and they started talking about "global warming," I thought it would peter out after a few years. Instead, Extinction Rebellion kids glue themselves to the highway and we've a Congressional caucus in the stadium. A bit of perspective should tell us Venus II isn't on the way. If tipping points leading to runaway greenhouse existed, it would have already happened way back in geological time. To manufacture Venus II, we'd have to get the CO2 out of the piles of limestone locking it up on Earth. Those piles are ten miles thick. Earth experienced periods with CO2 thought to be 2000ppm or higher, with dinosaurs walking around. tmiddles wrote: Indeed.

VernerHornung wrote:So you've got a much better handle and depth to your scientific understanding than I do so I'm especially interested in your take on Huffman. I think the simplistic cliff notes on his theory is that Venus, with almost all CO2, has the same warming from it's atmosphere that Earth does at the same pressure. So the measurements taken by the probes as they descended, when they reached the atmospheric pressure of Earth, showed that the temperature on/in Venus at that level was equivalent to Earth (adjusting for the distance to the Sun of course). He has:  ....1000 millibars, which is the sea level pressure of Earth, ..Venusian atmosphere is 339K.Earth ...is about 15ºC = 288K. Venus receives ...1.91 times the power per unit area that Earth receives, ...so the corresponding temperature on Venus, WITHOUT ANY GREENHOUSE EFFECT, should be 1.176 times that, or 339K And as the graph shows the temperature track on up from 1000 millibars. Now if mainstream science is "wrong" or "right" relative to what Huffman is saying, then asking "where is an example of that" is a good question. Is it 2 liter soda bottle guy? Is that really the cutting edge of confirming our calculations on CO2's impact? Look further and it's like a kid in the 8th grade failing to confirm anything and the infamous Bill Nye video where an experiment he now apologizes for is presented. I still don't get why you can't do what they did on Mythbusters, boxes with lamps on them and gas mixes, to confirm this stuff. Huffman's theory should be testable shouldn't it? To prove or disprove. I know I'm asking "us" a question "we" can't answer as we don't build experimental test setups.

tmiddles wrote: Don't be so sure. The stuff's confusing as hell. ~ I'm still trying to understand why Planck's law uses 3rd power of frequency but negative 5th power of wavelength, if frequency & wavelength are related by f = c/λ. I'll post something on it later if I can. The equation is stated in several formats, which boil down to four: by frequency B(f,T) = (2h/c^2) f^3 (e^(hf/kT) – 1)^(-1), intensity of radiation along a ray B(f,T) = (8πh/c^2) f^3 (e^(hf/kT) – 1)^(-1), radiation over whole sphere by wavelength B(λ,T) = (2hc) λ^(-5) (e^(hc/λkT) – 1)^(-1), intensity of radiation along a ray B(λ,T) = (8πhc) λ^(-5) (e^(hc/λkT) – 1)^(-1), radiation over whole sphere The ratio of 8π to 2 is just 4π, the area of a sphere of radius 1. That's easy. The exponents hf/kT and hc/λkT are easy, too: You change one to the other by substituting f = c/λ. hf/kt = h(c/λ)/kT = hc/λkT. But you can't do this with 2hf^3/c^2 in the top formula to get 2hc/λ^5 by wavelength. If you try, you get 2hf^3/c^2 = 2h(c/λ)^3 / c^2 = 2hc/λ^3. We're off by two powers of λ. Why? Mystery to me. Something about "density of states." The letters in the formulas are h = Planck constant = 6.67 x 10^(-34) Joule seconds k = Boltzmann constant = 1.38 x 10^(-23) Joules per Kelvin c = speed of light = 3.00 x 10^8 meters per second T is temperature, Kelvins is just ˚C + 273. tmiddles wrote: Let's make sure we have the right video; Bill Nye turns science into snake oil. The 2-liter hat I've in mind intros his channel as Erik Christensen, a physics/astronomy teacher at Florida Keys Community College. CO2 & heat lamp demo YouTube https://youtu.be/kwtt51gvaJQ This experiment's on the level, I'm pretty sure. They didn't do it when I took chem, but all the triatomic gases—H2O, CO2, N2O, NO2, SO2—are strong absorbers in the near infrared, so you should be able to heat any of them with a lamp. (A heat lamp is an ordinary incandescent bulb with a thicker filament for a somewhat lower emitting temperature.) The diatomic ones—H2, N2 and O2—are not. N2, O2 and air are transparent, so direct heating ala Huffman by visible light is out, and the 2-liter bottle here shows a heat lamp won't do it, either: One of the bottles was air, the other air enriched by CO2 from the fizzing Alka-Seltzer. (The tablets contain citric acid & baking soda that react when wetted and release CO2.) So we've disproved direct heating of air in the case of carbonated 2-liter soda bottles. But wait! Why is the CO2 bottle so bright when the air bottle is not? Is it just reflection off the outside of the left bottle hitting the camera lens while reflection from the other bottle misses the lens? If so, we're okay. But if that glow is the heat lamp lighting up fizz droplets, then we may have "Venusian clouds" in that bottle. Let's check further: tmiddles wrote: Huffman said only that "the Venusian atmosphere is heated mainly by incident infrared radiation from the Sun, which is not reflected but absorbed by Venus's clouds, rather than by warming first of the planetary surface..." Clouds absorb infrared, which is how the Weather Service makes those nighttime satellite cloud images. (The clouds are dark in infrared, so they publish the negative image to make the clouds look more normal to people.) Then he continues, "...the temperature profile, or lapse rate, for any planetary atmosphere is relatively oblivious to how the atmosphere is heated, whether from above or below. This denies any possibility of a greenhouse effect on Venus (or on Earth), much less a runaway one." Whether oblivious depends on how opaque the gases are. If they're opaque, the atmosphere will be heated at its top. If transparent, at its bottom. If partially transparent, as in real life, it's being heated in both places. Opacity depends on wavelength. Glass is clear in visible light yet black in ultraviolet, which is why people don't sunburn from exposure to sun coming through a window. Huffman concludes: "This has already been pointed out recently by physicists Gerlich and Tscheuschner, who have written succinctly, '...since the Venusian atmosphere is opaque to visible light, the central assumption of the greenhouse hypotheses is not obeyed.'" Almost true, since only 4 or 5% of the visible sunlight impinging on the top of Venus's atmosphere wends its way down to the Veneras, enough to permit photography but hardly full sun. Venus orbits at 0.72 AU from the sun and Earth is at 1 AU. By the inverse square law, Venus thus gets (1/0.72)^2 = 1.93 times as intense a sunlight as we do. Stefan-Boltzmann says radiance is proportional to fourth power of temperature, so absent other influences the temps should be T(Venus) = (4th root of 1.93) times T(Earth) T(Earth at 1 bar) = 288K observed. T(Venus at 1 bar) = 1.18 times 288K = 339K calculated. Huffman noted that at Venus's 1-bar pressure level (about 50 km above the surface), the air, if you can call a choking sulfuric acid soup by that word, is indeed close to 339K. The temperature profiles continue to match fairly well with Venus at 1.18 times Earth up to the 200-millibar level, where Earth's stratosphere begins. Huff's right about the globus therma people dismissing alternative theories, and what's worse, we never hear much about Venus at all from the IPCC. Such a remarkable coincidence deserves investigation, and explanation if those advocating greenhouse effect know why it should be discounted. Finally, Huffman cites a dissent from greenhouse mechanism by Gerhard Gerlich, a mathematical physicist at Karl Wilhelm Tech Braunschweig. This is at On the Barometric Formulas and their Derivation https://arxiv.org/pdf/1003.1508.pdf I downloaded it but the vector calculus is way over my head. The Navier-Stokes equations involve compressibility, turbulence & vorticity while intro students like me are taught only the special case of laminar, incompressible flow, Bernoulli's equation, which works for water in pipes. Gerlich uses these to show that winds are mostly horizontal on planets. Convection is analyzed as pressure-volume work with the ideal gas law. That's where we get "adiabatic lapse rate" in weather, where the temp drops about 10˚C for every 1000 meters you ascend in a plane. Gerlich's objection was, "...the greenhouse models are all based on simplistic pictures of radiative transfer and their obscure relation to thermodynamics, disregarding the other forms of heat transfer such as thermal conductivity, convection, latent heat exchange, etc." Thermal conductivity of air is very low (winter coats work because they trap air spaces) but convection is important on a planet, with rising warm air in the troposphere. It could be the whole damn thing's so complex the experts are flummoxed. Even if greenhouse effects are real, which I suppose they are, they might not be the only player in the game of keeping a planet from freezing. Gerlich feels the horizontal winds are important, and these are neglected in the IPCC diagram on the Earth's radiation budget. The defect in Huffman's analysis was his need to ignore the hotter, lower Venusian atmosphere which can't be compared to anything on Earth, and Mars is out because it's surface pressure corresponds to stratosphere on Earth. Huffman acknowledged these problems. In short, they're making political decisions while the science is still on the drawing board. Far from settled. All the theoretical mechanisms are settled, of course; we've had Planck's law since 1900 and "Clausius refrigerators" even longer. But the way basic theories work in a bustling atmosphere is liable to be filled with mousetraps to stick your toe into. ~ Gerlich has another paper I wanna see; I'll cover it later to best of my ability.

OK so I plugged f=1/λ in for Ef and you get: 8πhc/λ3 for the first term with the 2nd term comming out the same as Eλ. So seems fair to say they are not equivalent. Then I noted that to the right is shows that Ef gives you W/m2Hz while Eλ give you W/m2m so they are in fact not giving the same result. In the link it states that they are "the power per area per frequency or the power per area per wavelength". So frequency is the number of times per second and wavelength is the length of wave. So per frequency would be much larger than per wavelength for infrared at 700nm. It would be exactly c/700nm larger in fact, or c/λ larger. So if Ef is Eλ*λ/c, then 8πhc/λ3 becomes 8πhc2/λ4 but not to the λ^5th! arggh! So close.

The Planck constant, h = 0.00000 00000 00000 00000 00000 00000 000667 Joule seconds is usually written as 6.67 x 10^-34 so they don't have to mess with 33 zeros after the decimal point. The smallness of h is why people don't notice quantum effects in daily life; mostly it affects atoms or molecules. The units on your equations are correct, and they matter. The square meters and π tell us it's for energy radiated over a whole sphere. As for why f is upstairs to the 3rd power and λ downstairs to the 5th power, I think I have a clue. The Phys. Prof. had two of us young'uns hold the ends of a jump rope and excite it into a standing wave. Pair with the most nodes won, and nobody achieved more than three since you have jiggle the rope faster—the frequency—to get a higher number of nodes. tmiddles wrote: Getting the exponents is tough; it took me a while to arrive at a schema for it. Light was still viewed as a wave in Planck's day. So he proposed the radiation in a cavity radiator was a standing wave; it's convenient to assume a cubical shape. Let's start with a one-dimensional standing wave confined between walls, like this:  The following derivation's extreme slop (glad there's no real physicists here), but it's meant for concept only. The energy in a classical standing wave is proportional to the amplitude (how tall the up and down swings are) and to the number of nodes, so we model the cavity radiator as a hollow box with standing waves inside:  In the last part, I'll just put in Einstein's photon energy to get numbers that correspond to the energy of the standing waves near a particular frequency or wavelength:  This isn't the correct derivation; it just explains the exponents on f and λ. The numeral 3 emerged because I used a box. When a cubical box of L x L x L inches expands a small amount ΔL, the increase in volume is about 3L^2 ΔL. We can check that. Suppose the box is 30 inches on a side and expands by ΔL of 1 inch. Then initial volume: 27000 in^3 estimated increase: 3 x (30 in)^2 x 1 in = 2700 in^3 estimated final volume: 29700 in^3 exact final volume: (31 in)^3 = 29791 in^3 Pretty close, and the approximation gets better the smaller ΔL is. We speak of an "instantaneous rate of volume increase" for boxes, dV = 3L^2 dL, which is 2700 cubic inches per inch for a 30-inch box. The shape of the cavity doesn't matter very much, and we're interested in the rays outside the cavity, the ones that come out through the little hole. For that I'll need to derive the stuff I have above for a spherical shell, like the skin of a basketball. The numeral 3 should disappear, with 4π in its place instead. I'm slow, though, and they didn't spend much time on Planck's law in school. I'd forgotten about it until now. Max was a smart cookie. The whole point of the exercise is the "Stefan-Boltzmann" scream coming from that pair of ITN-IBdaMann speakers on the bookcase. With CO2, we have something basically like a Planck spectrum with a slot cut out in the infrared, like  The sunlight comes down with most of its energy in the slot where CO2 is transparent. Rays from the Earth come up near the right end where CO2 absorbs. The asymmetry is crucial to making the greenhouse work; otherwise the CO2 would just be blocking solar energy before it got to the surface. Never try to solve an NP-complete problem on your own with pencil & paper. |

Beyond my ability at the moment but I can revisit this later. Derivation is a great way to really understand so it's time well spent. So the classic greenhouse concept is the frequency valve: High frequency get's past, low frequency get's interrupted on the way out. Are there filters, like you'd put on a light or camera lens, that have this same property of transmitting high frequency and absorbing low frequency?

To show reality of effect, no exact value for average temp need be supplied unless the equations are sensitive to small differences in the figure. One puts in a figure close to the surface average and shows that an air (or CO2) envelope raises it. Gerlich's objection here is that order of operations matters: Integrating before taking a root leads to a factor 5√2/4 = 1.77 difference in mean temperature versus taking the root first and then integrating. Quite blatant: 279K instead of 158, greater than the difference between Florida and dry ice. This supposedly renders the averaging method worthless. Smith answers that "the average temperature is always less than or equal to the effective thermal radiation temperature" computed by Gerlich. Head-scratch time!

Visible light spectrometry uses diffraction gratings; I'm not sure how they do IR spectra. Error in my last post by the way—the slot in the CO2 is in the visible, not IR.
