Interestingly, in that situation, the non-CO2 absorption within that layer would itself be making the layer warmer than otherwise by absorbing more radiation than it emits.

Actually, though, most of the OLR originates from below the tropopause (can get up around 18 km in the tropics, generally lower)-- with a majority of solar radiation absorbed at the surface, a crude approximation can be made that the area emitting to space is less than 2 * (20/6371) * 100 % ~ = 0.628 % more than the area heated by the sun, so the OLR per unit area should be well within about 0.6 % of the value calculated without the Earth's curvature (I'm guessing it would actually be closer to if not less than 0.3 % different).

Only molecules made of at least three atoms absorb heat radiation and thus only such trace gases makes the greenhouse effect, and among these CO2 is the second most important after water vapor.

It does seem at first glance that a warm troposphere would warm the stratosphere, but the explanation that more of the earth - sourced infrared radiation is absorbed lower in the the troposphere by higher levels of CO2 makes sense if one thinks about the thermodynamic losses involved in the CO2 re-radiation processes; some of the earth - sourced infrared is transformed into kinetic energy and only a fraction is reradiated as more infrared radiation (if I'm understanding correctly).

Although a libertarian might well agree that CO2 absorbs / scatters IR radiation, and that this will produce a warming effect, and agree that this effect could cause problems, and could even agree that it requires the intervention of some agency, he doesn't have to agree with Read that this represents either a global catastrophe in the making, or a palpable «limit to growth».

Increased amounts of gases such as carbon dioxide make the atmosphere absorb long - wavelength radiation from the surface more strongly and also emit more radiation back down towards the surface.

But most of the infra - red radiation emitted by the earth's surface is absorbed in the atmosphere by water vapour, carbon dioxide, and other naturally occurring «greenhouse gases», making it difficult for the surface to radiate energy directly to space.

This is a quote from your link: «So even if water vapor in the lower layers of the atmosphere did entirely block any radiation that could have been absorbed by CO2, that would not keep the gas from making a difference in the rarified and frigid upper layers.»

Less well appreciated is that clouds (made of ice particles and / or liquid water droplets) also absorb infrared radiation and contribute to the greenhouse effect, too.

An international team of researchers report in Nature Communications that they made a computer model of the planet's atmospheric conditions: they included natural and human - triggered aerosols, volatile organic compounds, greenhouse gases and other factors that influence temperature, one of which is albedo: the scientist's word for the capacity of terrain to absorb or reflect solar radiation.

AGW is a hypothesis that makes sense, namely: — GHGs absorb outgoing radiation, thereby contributing to warming (GH theory)-- CO2 is a GHG (as is water vapor plus some minor GHGs)-- CO2 concentrations have risen (mostly since measurements started in Mauna Loa in 1959)-- global temperature has risen since 1850 (in ~ 30 - year warming cycles with ~ 30 - year cycles of slight cooling in between)-- humans emit CO2 and other GHGs — ergo, human GHG emissions have very likely been a major contributor to higher GHG concentrations, very likely contributing to the observed warming

This makes them better at absorbing energy from infrared radiation... which is why they are such effective greenhouse gases.

Then, especially when there is excessive cloud cover over the oceans, the Sun's energy absorbed above the clouds can actually make its way down to the ocean surface (and below) warming the oceans by non-radiative processes, not by direct solar radiation which mostly passes through the thin surface layer and could barely raise the mean temperature of an asphalt paved Earth above -35 C.

I think the question is actualized by the 2014 Donohoe et al paper, as they show that it is the absorbed solar radiation (ASR) that makes the earth warmer, perhaps together with IR downwelling radiation.

The reason, Werner said, is because the loss of snow and ice makes the earth's surface less reflective, meaning solar radiation — or heat — is absorbed in greater amounts by the exposed dark ocean or tundra.

The error made in the experiment was that c02 was way saturated!?! [i] JAMES: From doing my own digging around I have also had trouble finding the science that «proved» that CO2 absorbs infrared radiation.

Whatever the average regional temperature, it's hotter in the cities, because concentrations of traffic, business, heating, cooking, lighting and air conditioning generate what has become known as the urban heat island effect: what makes this worse is that the asphalt, tarmacadam, stone, brick, glass and tile of which cities are made absorb radiation but prevent ground evaporation as a natural cooling device.

A room - temperature cavity resonator produces radiation at a wavelength associated with blackbody temperatures down around absolute zero which is absorbed by hot food to make it hotter.

Your comment its correct for the sun's radiation heat but not for the infra red radiation from the Earth's surface that GHG's, whether natural or man made, absorb the absorption heat the atmosphere which re radiates up and down.

The lower sunlight means less radiation to be absorbed by co2, you can not make up for lower input because there is a limit on availability of radiation to absorb by co2.

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

The other point that I have been trying to make is that once a wavelength of radiation is absorbed completely, it doesn't matter how much more of the gas is added it just can not absorb any more of that wavelength.

Of course, it is as Willis says «a tinkertoy model» and there are various ways to make it somewhat more realistic (e.g., by having the shells be graybodies that don't absorb all the IR radiation but let some of it through).

What makes a good greenhouse gas is the ability to absorb long wave radiation, and the gases concentration

The theory is that the Ozone Hole, by allowing more of the UV component of the Sun's incoming radiation to make it down to low altitude rather than being absorbed in the stratosphere is providing an incremental energy increase to drive the strength of the SAM, and thus the degree to which Antarctica is isolated from more global weather influences.

Without water vapour, clouds shading the surface or the current 20 % of incident solar radiation being absorbed on the way down through the atmosphere, then nearly twice as much solar radiation would strike the surface, making it more like +5 °C.

It absorbs solar radiation converting it to heat and then warming the atmosphere, It also dissolve in the oceans lowering the pH (makes them more acidic) which interferes with phytoplankton, fish reproduction the production of coral and mollusk shells.

The energy in this radiation is made up from some of the energy leaving the bulk of the ocean plus some from DLR that was absorbed in the first few microns and then immediately re-radiated upwards.

Carbon dioxide absorbs solar electromagnetic radiation which makes it warm, That warmth gets passed to neighboring gas molecules and global temperature goes up.

Thus, a considerable part of the visible radiation is either absorbed or reflected, the interaction of vegetation with the photons from the visible region making the surface of the lands cooler and greener.

However, my main point was not so much about the «make up» of ozone but more about the possibility that as long as oxygen atoms and molecules absorb enough energy from UV radiation to alter their structure it may be that they also produce an increase in their heat content, which should be greater at any points nearest to the source — i.e..

-- Yes, it may be correct in so far as they can say that; «around 10 % of the wavebands emitted by IR radiation are made up of wave - lengths that can not be absorbed by «Greenhouse Gases» (GHGs), but that can not possibly mean that 0.04 %, in the case of CO2 concentration but certainly less than 10 % of the Atmosphere as a total has got what must be a «supernatural» ability to stop LWR.

This made it possible to dissect each layer of Earth's atmosphere and work out how it might absorb infra - red radiation.

As long as you were absorbed close enough to the surface, that you, as the radiation, can still see the surface, it the random direction you are re-emitted is downward, you have a high chance to make it back to the surface.

The inner wall of the igloo, having absorbed some of the radiation from you, and because snow has air pockets and is not as good a conductor as an equal thickness of metal, it is cooler than you but warmer than a metal shell, so it does, in fact, radiate some of its warmth and make you warmer than you would be in a metal igloo.

But at the very least, the soot concentration measurements show that the soot is there, and the most solid part of the deductive chain — the fact that soot makes snow absorb more radiation — is already firmly in place.
