The change in radiation balance is more heating of the oceans at one side (specifically high in the subtropics, as expected), but more heat released at higher altitudes, thus somewhere acting as a net negative feedback to higher sea surface temperatures.

In the absence of solar heating, there is an equilibrium «skin temperature» that would be approached in the uppermost atmosphere (above the effective emitting altitude) which is only dependent on the outgoing longwave (LW) radiation to space in the case where optical properties in the LW part of the spectrum are invariant over wavelength (this skin temperature will be colder than the temperature at the effective emitting altitude).

Now, I think it was in 1956 that atmospheric physicist and sometimes - weapons designer Gilbert Plass (who needed to know about IR to fire heat - seeking missiles up the tailpipes of jet fighter at high altitude) noted that CO2 in the upper troposphere could block the escape of IR to space: The Carbon Dioxide Theory of Climate Change, Gilbert Plass (1955)(abstract) In the full paper, available at the above link, Plass spells out the previous notion which his research overturned:

In 1896 Swedish chemist and Nobel laureate Svante Arrhenius used Langley's bolometer to measure the heat from the Moon at various altitudes above the horizon in order to estimate the dependence of atmospheric heat trapping on amount of water vapor and CO2 along the line of sight to the Moon, a much longer path near the horizon than at 45 degrees.

And there was NO effect on temperatures at lower altitudes over that time, even from this massive heating event where about 20 % of the entire atmosphere warmed.

The effects of very short wavelength UV on photochemical reactions in the stratosphere leading to heating at very high altitudes is something that is under appreciated in the climate science community but the meterologists would have likely let them know when to look for these affects.

orgConsider David Keith's idea, presented in an article published in the Proceedings of the National Academy of Sciences, of deploying a fleet of thermostatically self - regulating, mirror - coated, nanotechnology flying saucers, which would be programmed to assemble at the latitude and altitude appropriate to reflect back the precise amount of sun light necessary to offset the global heating associated with human - caused CO2 emissions.

When clouds condense back to water they give up the Latent Heat of Vaporisation at that altitude and the radiant energy is closer to top of atmosphere to pass to that great heat sink in the sky: SpHeat of Vaporisation at that altitude and the radiant energy is closer to top of atmosphere to pass to that great heat sink in the sky: Spheat sink in the sky: Space.

That fluctuation is amplified by land surface temperatures in the same latitude band of about the same area, because the land surface temperatures are at a higher average altitude with a lower average specific heat capacity and the (Tmax + Tmin) / 2 method of determining «average» amplifies the variance.

«Classic thermodynamics», tempterrain include the original Clausius statement of the Second Law of Thermodynamics, which only related to heat transfer at the same altitude, so that there was no change in potential energy.

CO2 radiation at high above is cold (depends on altitudes, latitudes, and longitudes, say from 0degreeC to -60 degreeC) can not radiate net heat back to the Earth which is at a higher temperature.

It is heated at the bottom and it loses its heat in altitude.

In order to force a temperature decline at the adiabatic lapse rate, there must be some combination of both heating from below and cooling from above that would otherwise drive the rate of cooling with altitude beyond the effective lapse rate.

Does not your thought experiment fail, because most of the molecules in the atmosphere are all at the same heat (kinetic energy), while the difference in temperature with altitude (on a thermometer) is simply an effect of the number of molecules you meet (pressure and density).

The black soot soaks up heat and when the snow gets dirty it melts more quickly and, at such high altitudes, the effect is magnified.

Since warm air is being moved poleward at low altitudes, the wind flow is no longer associated with the direct heat engine of the Hadley cell.

Thus the warm wire at the top of the collumn (at say +30 oc) can not «heat the air» at high altitude, because the individual molecules at altitude are already at something like +30 oc (in terms of their individual kinetic energy)..

That might give a bit of pause for thought about density and its effect on the ability of air packets at different altitudes to retain the heat of the Sun.

If the atmosphere of Venus became truly opaque to incoming solar radiation at some altitude above the surface, the atmosphere below that point would be isothermal assuming no heat input to the surface from the core of the planet.

An atmosphere in which heated gases can rise to altitude, but can not lose energy and descend runs far hotter than an atmosphere in which energy loss at altitude can occur.

-- convective circulation in the troposphere is driven by heating at low altitude and energy loss at high altitude.

However, it is much easier to figure out what happens when you add more radiative gases to an atmosphere that already has them: And, the answer is that it increases the IR opacity of the atmosphere, which increases the altitude of the effective radiating level and hence means the emission is occurring from a lower - temperature layer, leading to a reduction of emission that is eventually remedied by the atmosphere heating up so that radiative balance at the top - of - the - atmosphere is restored.

The mechanism which prevents H2O vapour from overheating the world is cloud cover, due to the easily provable fact that heated moist air rises, expanding, cooling and condensing into cloud cover in the rarified air at higher altitudes.

This heating of the air «from above» explains the fact that the lapse rate is between - 5 K / km to — 8 K / km depending on the exact value of Ch at the place, altitude and time considered and not the adiabatic lapse rate of -9.8 K / km.

(Any higher and they start to suffer stratospheric heating due to the vertical temperature profile reversing at the tropopause — the lapse rate changes sign and the air gets warmer instead of colder with altitude.)

Convection at lower altitudes will punch through the thicker lower layers allowing a much more direct path for radiative effects to become efficient and unhindered in delivering the heat to space.

The crowd of government - financed alarmists artificially introduced this signal by excluding Canadian, Siberian, high - altitude and other «inconvenient» measurements from data sets, by various «adjustments» fitting the desired outcome, by placing meteorological stations on airport tarmacs, at air conditioners» exhausts and in other artificially heated places, and by blatantly omitting, negating, and even reversing (as in prof. Mann's case) actual results.

At higher altitudes radiation heat transfer becomes more significant and OLR is emitted and the parcel cools.

By looking at atmospheric profiles above Gan Island, they could see how clouds and moisture changed which altitudes were heated over the course of each cycle of the MJO.

A drying of the atmosphere — that the researchers note — takes place in the subtropical subsidence zone (the 30 degrees latitude) but expands towards the 30 - 45 degrees latitude — Earth's Meditteranean climates, where their model suggests net cloud cover would actually decrease most (see dotted line in first image in this article, at top)-- most notably around 500 hPa (roughly translating to a height of around 5 kilometers of altitude in the troposphere) decreasing albedo and increasing solar heat absorption, therefore net climate warming.

To that you answer if the temperature ever starts to rise, due to say volcanic heat, or upwelling to water's surface, the heat is immediately removed by the power of evaporation as infrared - resonant gases chug heat straight up through the atmospheric mix to belch it out radiatively at higher altitude; while simultaneously dragging other, non-infrared resonant gases upward with them, to also dump THEIR heat radiatively, from a higher position than they would have, had the refrigerative cycle not taken place.

One of the key insights in Lindzens 2001 adaptive iris hypothesis, the others being the latent heat left at altitude upon water vapor condensation thanks to convection and the temperature lapse rate, and the lowering of humidity (so water vapor feedback) from the resulting precipitation.

The basic idea was that reducing the difference in temperature between the ocean (at some fixed depth below the skin) and the atmosphere (at some fixed low altitude) through warming the atmosphere reduces the heat loss.

However, the large difference in dry vs wet lapse rate is not due to the presence of water vapor changing the average Cp, but instead due to the progressive condensation of vapor to liquid or solid at altitude (heat of condensation being released).

He doesn't mention that the radiosonde datasets are regarded as questionable for climatological purposes at higher altitude due to radiative heating / cooling effects on the instrument packages.

I just tried jotting down, step by step, a sequence of events beginning with evaporation from the sea surface, absorption of latent heat, subsequent condensation at altitude into opaque liquid droplets and the release of selfsame latent heat.
