In other words, with the warm atmosphere there, net radiation leaving the surface is 150 W m^-2, but without the atmosphere in the way, it would be 390 W m^-2. Typical actions include reducing waste, silviculture, regenerative agriculture, alternatives to fossil fuels (whose extraction can be polluting or destructive), fewer cash crops, combining conservation with careful use and cutting the impact per head and probably numbers of conventional livestock. The thermal gradient in the atmosphere is a consequence of the gradual reduction in pressure as the height increases, arising from the action of gravity. Those ranges dont overlap, so to oxygen and nitrogen, its as if the infrared waves dont even exist; they let the waves (and heat) pass freely through the atmosphere. Impossible. Thermodynamic Properties of R744 (Carbon Dioxide - CO2) Critical Pressure: 7.377 MPa, Critical Temperature 30.978C Ideal Gas Constant of Carbon Dioxide: R = 0.1889 kJ/kg.K. The greenhouse effect is when that heat tries to escape Earth, but some of it is trapped by different chemicals in the atmosphere, such as water vapor, carbon dioxide and methane. There are selection rules for possible energy transtions in molecules. Recently, I became embroiled in an online debate on the subject of anthropogenic global warming (Claim) originated by a talk radio host, who was hostile to the claim of anthropogenic global warming. . carbon dioxide, (CO2), a colourless gas having a faint sharp odour and a sour taste. Thermodynamic Properties of Saturated Carbon Dioxide Enthalpy and Entropy Tables for Temperatures -50.0 to 31.0 C. The article notes that Water is indeed a greenhouse gas (and) it absorbs and re-emits infrared radiation, and thus makes the planet warmer.The article also notes that warmer air holds more water The interaction with radiation as well as intermolecular interactions are described by quantum mechanics. I have always suspected as much. Question Number: 104 PDR Number: BI-70 Date Submitted: 21/11/2022 Department or Body: Commonwealth Scientific and Industrial Research Organisation 1. -Im not saying human activity doesnt add to this warming trend; it does. Decreasing co2 will lead to more starvation and more war. Therefore the statement of the IPCC concerning back radiation is untenable. I wonder whether the real intensity of the sun is increased more than the weather bureau air temperature quoted, and how much is it increased? I also read that the net effect of low and high clouds is currently net slightly cooling. So we know that even very low, natural levels of carbon dioxide and other greenhouse gases can make a huge difference in Earths climate. Havent you ignored the large effect of water vapor when you conclude that even very low CO2 and other greenhouse gases can make a huge difference Didnt you just incorrectly imply that water vapor percentage is very low by not mentioning it or its effect is minimal? How can this be? Carbon dioxide, for example, absorbs energy at a variety of wavelengths between 2,000 and 15,000 nanometers a range that overlaps with that of infrared energy. It is given by, N(BEC,T) = A x (CO2) x exp{-667.4 / (kB x T)}. I have never given much thought to waste heat from human activity. IUPAC Standard InChI: InChI=1S/CO2/c2-1-3. CO2 makes up only about 0.04% of the atmosphere, and water vapor can vary from 0 to 4%. Not my idea of optimal. But it doesnt show that at all. Credit: NASA, With CO2 and other greenhouse gases, its different. Molecules of carbon dioxide (CO 2) can absorb energy from infrared (IR) radiation. If the airs cooler than the surface, it wouldnt. To get energy integrate power per unit area over time then multiply by area. ie The air temperature is quoted according to scientific instruments, but the actual radiation intensity is much higher. How come experiments that claim to prove CO2 is a key driver of AGW use CO2 concentrations at exaggerated levels instead of the .03% to .06% we are concerned about. Vibrational transitions are in the infrared and rotational transitions in the microwave region of the electromagnetic spectrum. You are correct re convectional cooling, and as such means that convectional heating is also applicable. Im sorry, that is fakery to fool children. the the absorption properties of CO2 have had little affect on the lapse rate. @article{osti_556797, title = {Heat capacity of aqueous monoethanolamine, diethanolamine, N-methyldiethanolamine, and N-methyldiethanolamine-based blends with carbon dioxide}, author = {Weiland, R H and Dingman, J C and Cronin, D B}, abstractNote = {New data are reported on the heat capacity of CO{sub 2}-loaded, aqueous solutions of monoethanolamine (MEA), diethanolamine (DEA), N . Increasing greenhouse molecules, increases the amount of energy that gets caught and sent back. Quite simply, it does not. Anyone thinking that must have been emptying those bottles wholesale! It would all rain out because temperature determines how much moisture can actually be held by the atmosphere.. The mentioned greenhouse effect of CO2 is not in accordance with the molecular properties of CO2. With no mass effective way to decrease the amount of CO2 in the air it will be hard to reverse this effect unless a different form of combustion and transportation is developed. And because water has effect too, GHC effect is much smaller? Less CO2=less plant life=less radiant energy from the sun being used during photosynthesis. Cooled CO2 in solid form is called dry ice. g). Temperature - Specific heat of Carbon Dioxide gas - CO 2 - temperatures ranging 175 - 6000 K. Carbon dioxide - Thermal Conductivity vs. As a certified infrared thermographer, I have always had significant misgivings regarding the proposition of CO2 as a greenhouse gas on the basis of it absorbing and scattering emitted infrared from the earth, thus retaining this energy within the atmosphere. Surely we can and will adapt, and a big part of adapting means moving away from fossil fuels. Stand. And yet global greening grows to 7% and beyond from co2 fertilization. It would seem that if N2 and O2 are transparent to incoming radiation that the introduction of CO2 would also act to insulate the incoming radiation and reflect some of it back into space as well as reflect some of the exiting radiation (from the earth) back to the earth. 6.8 x 1014 s-1 had to be 6.8 x 10^14 / s and 5.5 x 1010 s-1 had to be 5.5 x 10^10 / s. The revised version of the comment appears below. That is just dishonest surely. Can we stick with real science? Copy Sheet of paper on top of another sheet. However under atmospheric conditions the excited molecule suffers many collisions during that period which convert the excitation energy into translational and rotational energy of the collision partners. Challenge 2 seems a bit absurd, and is a thermal transfer issue. what does the temperature in the left and right is for? The altitude, above which there are no more appreciable greenhouse gasses will appear to be the radiating temperature at that point (often called outgoing long wave radiation). Ultimately, any increase in the amount of heat-trapping means that the Earths surface gets hotter. In the radiation option, a part is kept here and a part goes in space and is lost. Actually it can easily simulate the temperature changes in air, land and oceans according to the waste heat allocated to them based on simple thermodynamic calculations. If Mars is 95%co2 how come it is not hotter. Yet the average temperature of Venus is only about 15 times higher. The heat capacity of solid carbon dioxide has been measured from 15 to 195K. If you want to promote your products or services in the Engineering ToolBox - please use Google Adwords. The IPCC explains the greenhouse effect in the atmosphere in their frequently asked questions as follows: Much of the thermal radiation emitted by the land and ocean is absorbed by the atmosphere, including clouds, and re-radiated back to Earth. However, it became very apparent to me reducing usage cant be all that bad. Note the light source would need to be turned on and off every 12 hours and assumes the sun gives off a constant radiation over a 12 hour period, which I was not aware it did given the elliptical oscelating orbit. harrie, Excitation by 150 -210 nm radiation leads to photodissociation of CO2. It is one of the "greenhouse" gases responsible for global warming. Great explanation of the greenhouse property. Why dont they use ambient air and try the same experiment? The more CO2 molecules there are, the more infrared radiation gets interrupted and sent back to earth, instead of out to space. Unfortunately, we dont have thousands of years to wait for nature to absorb the flood of CO2. It would be helpful to find if the concentration O2 in the atmosphere is affected by human actions. It is the monoatomics (Ar) and homonuclear diatomics (N2, O2) which are the actual greenhouse gases. (The) Stefan-Boltzmann constant is how much radiation is given off an OPAQUE surface at a given temperature.. -Im not saying trying to minimize environmental impact isnt worthwhile. They leave out the global greening caused by c02 fertilization which = more oxygen = thicker atmosphere because of an over simplistic empty bottle experiment done over a hundred years ago. I assume the other types are a product of burning or combustion, how do those trace gases sty up in the clouds ?-for years. More plant growth is healthy for the planet no matter how you look at it! The quantum yield (T) for emission of radiation by CO2 (0110) at temperature T is given by (T) = kr / { kr + k1(T) + k2(T) }. We are experiencing a warming trend. It absorbs and re-emits infrared radiation, and thus makes the planet warmer. Table shows specific heat capacity of selected gases, solids and liquids. For full table with Imperial Units - rotate the screen! This may not fully refill the loss of O2 as forests are destroyed. Null results are extremely important in science otherwise it just becomes Groupthink. Credit: Jack Cook/Woods Hole Oceanographic Institution. He is saying that as CO2 concentrations increase in the atmosphere due to other means (e.g., by combustion of molecules that include carbon such as petroleum, coal and wood), that more infrared radiation that would otherwise radiate out into space is being reflected back to earth. Some of our calculators and applications let you save application data to your local computer. And that the full effect of CO2 is to cool Earth. Silicon Dioxide | SiO2 or O2Si | CID 24261 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities . The absorption range for CO2 is around 11 to 18 microns. Justsplit molecular weight of CO2 by Avogardo number to get weight of CO2 and then start to double it. the increased abundance of carbon dioxide is slowing the rate at which heat escapes through the top of Earth's atmosphere. Any observed 667 cm-1 radiation in the atmosphere originates from the sun, directly or through Raleigh scattering by CO2 in the upper atmosphere. I chose this link because of a comment made regarding the use of carbon dioxide as a refrigerant, alleging that this fact makes climate change due to gasses like CO2 highly unlikely. We don't save this data. Sequestering plant food (CO2) will make the problem worse. At some point CO2 does its job of catching a sky traveling photon only to re-emit it at another random solid angle. Carbon makes up about 0.025 percent of Earth's crust. Unfortunately, neither you nor I know the exact conditions of the experiment and what temperature the CO2 gas was at. Please read AddThis Privacy for more information. Suppose the sun is delivering power to the surface over time transferring energy In addition, trace amounts of a substance can have a large impact on a system, explains Smerdon. So, CO2 or H2O near the surface radiate at a higher temperature than those same molecules higher up in the atmosphere. Enjoy! Chris, What keeps me up at night is the loss of large swaths of arable land and ocean fish stock depletion. So one warming property and two cooling properties. I submitted a revised version with a different notation of powers of ten. To convert heat values to joules per mole values, multiply by 44.095 g/mol. Since the science is settled, you no doubt have that explanation handy and it will no doubt be in peer reviewed form. Nickerson, A survey of vibrational relaxation rate data for processes important to C02-N2-H20 infrared plume radiation. And then at the end, note that anthropogenic CO2 has two properties that cool. The carbon dioxide which is cold, would have to be on fire to register on the misadjusted FLIR cam, and so effectively blocks the flame like a cold smoke screen. an CO2 (0110) by radiation with wavenumber 667.4 cm-1.This is the strongest infrared absorption of CO2 and therefore the main process for excitation of CO2 by infrared radiation from the earths surface. But CO 2 is only good up to a point - beyond that point, Earth's temperature warms up too much. The equation is a radiative heat transfer equation the units are expressed in power per unit area, not energy. Impossible. More importantly, it also tells us that the rate of increase of atmospheric CO2 in the current era has no precedent, i.e. Birth control and insulation will help. Earth's carbon dioxide levels are about 420 parts per million, compared to 280 before the industrial revolution and the Earth has warmed about 2 degrees (1.1 degrees Celsius) in that time. All of it escapes. In addition, the heat capacities of the above amines were also measured from 303.15 K to 353.15 K at an interval of 5 K. 1680 Jg-1 B. Cause its a little lower then 400? However, nobody has published a single paper demonstrating heating from such a mechanism. What is the rate of decay of CO2 to return to reasonable levels? raise is 2.5 %. I might suggest that cloud cover of all types have a great deal of influence over regulating radiation flux impinging on the surface. Carbon dioxide (CO 2) is the primary greenhouse gas emitted through human activities.In 2020, CO 2 accounted for about 79% of all U.S. greenhouse gas emissions from human activities. DA is the local density of air, FC is the fraction of CO2 in air. CO2 is used as a refrigerant because the CFC / HCFC / HFC refrigerants are problematic for the ozone layer. The climate has changed in human history (medieval warm period, ice ages) and humans have always been able to adapt. The deactivation rate may be calculated using data from J. https://blogs.ei.columbia.edu/2021/02/25/carbon-dioxide-cause-global-warming/. The Earth has become five percent greener in 20 years. The best, most complete and correct answer below is from Lisa Goddard. However, I find the statement Unfortunately, we dont have thousands of years to wait for nature to absorb the flood of CO2. https://labs.selfdecode.com/blog/carbon-dioxide-poisoning/. In total, the increase in leaf area over the past two decades corresponds to an area as large as the Amazon rainforests. All the recent warming can be attributed to human activity. When that infrared light strikes the ground, what do you think happens? Seeing as CO2 have been known and proven since early 1800s to absorb and radiate heat, your statement that greenhouse gases have no affect creates a conflict in your statement. The highest annual increases seen in CO2 precede global cooling. Their values are A = 6,022 x 10^23 and kB = 0.6952 cm^-1 / K. The number of photons NP emitted per second by CO2(01^1 0) is given by, With the energy EP of a photon at 667.4 cm^-1 = 1325.4 x 10^-23 J, the amount of energy E(667 cm-1 ) radiated per second from 1 m3 air is given by. Use a world with a normal airshield, but without CO2. These have to be treated quantum mechanically. Almost any discussion of global warming begins or ends with carbon dioxide. Whatever we do, even if we burn every last grain of coal and drop of oil, we will never completely destroy earths life sustaining climate. He is also warning that he thinks getting to net zero would insufficient to avoid the long term effects of climate change because current levels are already too high and we will therefore need to find ways to reduce the concentration to safer levels. So, what is your opinion of what a reasonable level of CO is? Distribution matters. 2 = Signifies that at 70F, the compound is below the normal boiling point and only the equilibrium vapor is present at 1 atmosphere. The hybridizations of carbon and oxygen in carbon dioxide are a) sp and sp 3 b) sp 2 and sp 3 c) sp and sp 2 d) sp and sp e) . Therefore I modified the text to indicate superscripts with the symbol ^. The earths atmosphere is much much more complex! The basic reasons are that both the thermal energy kB x T and the density of air larger. I have a very image oriented mind and here is the image I conjure up regarding the phenomenon. how is the Earths tempereature measured ? Prepared for Air Force Rocket Propulsion Laboratory, October 1973, Distributed by National Technical Information Service, US Department of Commerce, 5285 Port Royal Road, Springfield VA. 22151. Its not. Do the profits of fossil fuel companies matter more than human lives? thank you so much. You are confusing the fraction of emissions with the fraction of build-up. Suppose, it was 70 degrees worldwide, so emitting roughly equal amounts of IR radiation per square meter everywhere, where would that energy come from ?, the sun?, no way. Capture of electrons emitted from the sun may produce the anion CO2.Reaction of CO2 with solvated electrons in water droplets will also produce the anion CO2. Plus, since none of them can replicate past climates they cant predict the future. IUPAC Standard InChIKey: CURLTUGMZLYLDI-UHFFFAOYSA-N. It seems to me that transmission through miles of atmosphere would be completely blocked once any level of gas was present and the addition of more gas would make no difference. of the earth leads to more IR radiation, outside the greenhouse windows, leaving us forever. Entropy, kJ/kg-K . The universe climate is irreversible. It is exhaled by Duplicants and occurs naturally in almost all Biomes. The curve between the triple point downwards to zero pressure shows the sublimation point with changes in pressure (Sublimation: transformation from solid phase directly to gas phase). Such as the exact radiation frequency and bandwidth selected for detection and how an intensity profile as a function of height above ground is extracted from the total energy measured. The important question is which constituents of the earth surface emit radiation at the specific frequencies required for these transitions in CO2 at the actual surface temperature. After absorbing this radiation from the sun, the earths surface radiates some of it back into space in the form of infrared radiation which has a little bit longer wave length than the various visible light wavelengths we see. This excludes homonuclear diatomics, with the exception of O2 which has a triplet electronic ground state allowing magnetic dipole rotational transitions. So why is the whole earth at a nice pleasant 80F during a Greenhouse period with co2 10 times higher then today? The rate constant for bimolecular deactivation by ground state CO2 or N2 depends on temperature T. For instance in the case 200 ppmv of CO2 in the air the rate of deactivation by collission with N2 amounts to 6.8 x 1014 s-1 at 288 K at ground level and to 5.5 x 1010 s-1 at 198.5 K and 80 km and above sea level. Is CFC no more depleting the ozone? 150 ppm is a threshold. What you are saying only holds true in the 4.3 and 15 micron absorption bands. The greenhouse gas mechanism does not exist. The heat of vaporization at the sublimation point, 194.67K, was found to be 6030 cal./mole. So if CO2 would be ONLY GHC shoudnt each doubling increase temperature by 32K/137? The curve between the critical point and the triple point shows the carbon dioxide boiling point with changes in pressure. The greenhouse effect is when that heat tries to escape Earth, but some of it is trapped by different chemicals in the atmosphere, such as water vapor, carbon dioxide and methane. The experiment with a bottle full of CO2 vs normal air is not a comparable experiment to prove the hypothesis of the earths warming as the hypothesis is 0.035% vs 0.04% creating a 2 degree increase is the issue, so the experiment would be to have a comparable increased amount of CO2 in one bottle vs the baseline and to see if there is a 1-2 degree increase in temperature in the CO2 bottle vs the baseline bottle. There are 3 ways that energy can be transferred: conduction, convection, and radiation. pages 25602561, except for critical temperature line (31.1C) and temperatures 30C and below, which are taken from Lange's Handbook of Chemistry, 10th ed. IUPAC Standard InChI: InChI=1S/CO2/c2-1-3. The IPCC explains the greenhouse effect in the atmosphere in their frequently asked questions as follows: Much of the thermal radiation emitted by the land and ocean is absorbed by the atmosphere, including clouds, and re-radiated back to Earth. If CO2 were to cause this increase it would need to form 10% of the atmosphere, assuming it was totally opaque to heat transfer. All the natural sources are matched by natural SINKS. It requires higher pressure than the CFC, HCFC or HFC molecules, but thats a tradeoff thats apparently acceptable. 100%, none of it escapes and this has been the case for centuries. We believe this because of the preponderance of evidence found in the the fossil record the tells us so. The processes mentioned above initiated by solar radiation decrease the concentration CO2 at heights above say 40 km, resulting in both more 667 cm-1 solar radiation reaching ground level and less Raleigh scattering of it into space. To write about temperature in percent one must use Kelvin so 1.5C rise is only 1.5/288 = 0.5%. Every greenhouse growers will tell you that 420 ppm co2 is a fraction for what these co2 starved plants need today. By the same token, the higher molar heat capacity of CO2 convectively transits more energy than bulk air. In order to convert them to the specific property (per unit mass), divide by the molar mass of carbon dioxide Such issues are very well known in standard Chemical analysis, Any good chemistry book on spectroscopy can help you further. But how can we remove it from from the atmosphere yet daily industries are evolving. Above sea or above forests or above desserts? The author seems to have forgotten that plants take up CO2. This animation shows a molecule of CO 2 absorbing an incoming infrared photon (yellow arrows). Greenhouse gases like carbon dioxide and methane absorb the infrared energy, re-emitting some of it back toward Earth and some of it out into space. R-744 is seen as the 'perfect' natural refrigerant as it is climate neutral and there is not a flammability or toxicity risk. So we know that even very low, natural levels of carbon dioxide and other greenhouse gases can make a huge difference in Earths climate. Your argument conflates infrared radiation with heat, but they are not the same thing. Before humans began burning fossil fuels, naturally occurring greenhouse gases helped to make Earths climate habitable. Atmospheric carbon dioxide plays an important role in maintaining surface temperatures. Credit: Evans 2006 via Skeptical Science. Carbon dioxide is the fourth most common gas in our atmosphere and its concentration is increasing. Carbon dioxide gas is colorless and heavier than air and has a slightly irritating odor. Google use cookies for serving our ads and handling visitor statistics. Chemical, physical and thermal properties of carbon dioxide:Values are given for gas phase at 25oC /77oF / 298 K and 1 atm., if not other phase, temperature or pressure given. Looking at any long-term lag (more than three months, the time it takes CO2s Green property to create life that cools) proves this point. If you expose them both to a heat lamp, the CO2 bottle will warm up much more than the bottle with just ambient air, he says. Convection is a special case of conduction in which fluid flow (air in this case) is taken into account as a heat distribution mechanism, and influencer of heat transfer coefficients (I got an A- in my first semester of heat transfer), but ultimately it is still conduction. Moreover, more CO2 cant simply mean increased oceanic evaporation because if that were true there would be runaway evaporation causing more greenhouse gases until the oceans boiled away. That sounds faintly ridiculous. This was actually the least contentious response. Ref. In the climate discussion the fate of excited CO2 molecules in the earths atmosphere has been ignored. That is unless you can prove CO2 doesnt do any such thing? The mentioned greenhouse effect of CO2 is not in accordance with the molecular properties of CO2. While I can see the data graphs that imply this, is there detailed modelling that supports this? While it is non-toxic there is still risk if a leak occurs in an enclosed area as R-744 will displace the oxygen in the room and could cause asphyxiation. (kPa) Enthalpy, kJ/kg . Hi James, heres a slightly experiment where cold CO2 is definitely not an issue, and it shows the same results: https://youtu.be/Rt6gLt6G5Kc?t=107 Hope this helps. Why would you want to go back to a climate that was bad for 700 years ? IUPAC Standard InChIKey: CURLTUGMZLYLDI-UHFFFAOYSA-N. The Green effect overpowers the Greenhouse effect after three months and is lasting. Properties, uses and applications for carbon dioxide CO2 as gas, liquid, solid ice. Seems like a lot of conjecturing. a negative contribution. What is the quantative relation between absorbtion and concentration for CO2? -Im not saying plants and trees do not have a net cooling effect. So I guess its ok to return to those conditions, too? Overall, increasing CO2 and other greenhouse gasses reduces the earths ability to cool itself off by radiating energy into space. That is ridiculous. Part of the heat which would previously escape as infrared is now trapped. In reality, not a single action, but many absorbtions and re-emittings. Cookies are only used in the browser to improve user experience. CO2 is roughly evenly distributed around the world and relative to height, water vapour is not. Heat ; Trenching and Excavation ; Personal Protective Equipment ; Fall Prevention ; . In the climate discussion the fate of excited CO2 molecules in the earths atmosphere has been ignored. At 50 km height with 400 ppm CO2 and 25000 ppm H2O, the collision rate between CO2 and H2O molecules is calculated to be 6.14 x 10^33 / (s m^3) . Because of the limitations of traditional refrigerants, the application of trans-critical CO2 technology in domestic gas conditioners and other fields is becoming increasingly popular. Climate scientist James Hansen has suggested that we should try to limit CO2 to 350ppm, although for thousands of years, natural cycles didnt bring it above 300ppm: https://climate.nasa.gov/vital-signs/carbon-dioxide/. If you want to promote your products or services in the Engineering ToolBox - please use Google Adwords. If you would measure the infrared output of the earth at sealevel and you would measure this outside the atmosphere, you would find a difference. Ergo, there is a net gain of heat on earth. If CO2 is not responsible for temperature increases why is Venus hotter then Mercury? Apply exactly equal heat to all 3 containers in a controlled environment for the same length of time. The lowest increases seen in CO2 annual increase precede explosive global warming. You Asked: Dinosaurs Survived When CO2 Was Extremely High. The pressure kept increasing while it received more water until the level we see today. Oxygen and Nitrogen in the air mostly ignore it, but Carbon Dioxide molecules have the geometry and composition that allows them to absorb the radiation of this wavelength. Specific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics. In other words the greenhouse gas molecules catch the infrared energy trying to escape earth, and throw some of it back to earth. Data obtained from CRC Handbook of Chemistry and Physics, 44th ed. Photoionization of CO2 yields the cation CO2+. Please read AddThis Privacy for more information. AFAIK, Please read Google Privacy & Terms for more information about how you can control adserving and the information collected. its water ! Thats the simple answer. In your final sentence you say that radiation increases greenhouse molecules. Yeah, the Earth has survived a lot of things. There is NO net warming effect due to so-called greenhouse gases. This website uses cookies as well as similar tools and technologies to understand visitors' experiences. 0.015 (DTU/(m*s))/C. Good science. 1, by emitting IR radiation, what the IPCC sees as dominant, in any direction, partly into space, partly back to earth. Since the solid angle of these emitted photons will occur in any random x,y,z coordinate, only 50% should be sky bound Correct? Thats adapted from the Clough and Iacono study, Journal Of Geophysical Research, Vol. what is the average distance an infrared photon travels before encountering a CO2 molecule at 400 ppm and STP? And then the other important factor is Venus has all these crazy sulfuric acid clouds.. Without them, the planets average temperature would be below freezing. Most of Earths greenhouse effect comes from water vapor and clouds, which together account for about 25 K of the Earths 33 K difference from the radiative equilibrium temperature (CO2 accounts for most of the rest). 194.67K, was found to be 6030 cal./mole while I can see the data graphs that imply,!
