OLR increases in the optically thinner bands would lead to atmospheric warming in general, but this has to be accompanied by OLR decreases somewhere, such as in optically thicker bands (and always in the band where optical thickness was added, assuming positive lapse rates everywhere as is the case in a 1 - dimensional equilibrium model with zero solar heating above the tropopause, or at least not too much solar heating in some distributions), which will tend to cause cooling of upper levels.
The haze reduced the seasonal average solar radiation absorbed by the equatorial Indian ocean by as much as 30 to 60 W m − 2 during September to November 1997, and increased the atmospheric solar heating by as much as 50 % to 100 % within the first 3 kilometers.
I agree that the non-grey nature of atmospheric optical properties is important to the issue of stratospheric cooling and that an increase in a greenhouse gas like CO2 can cause stratospheric cooling even without solar heating of the stratosphere.
Jet streams are caused by the earth's rotation and atmospheric heating by solar radiation.
In the case where there is a skin temperature that only depends on solar heating of the planet with no solar heating above the troposphere, an increase in GHG forcing would still result in upper atmospheric cooling, but this cooling would only be transient.
Moreover, the atmospheric temperature gradient is mitigated by the absorption of solar radiation within the atmosphere (also latent heat deposition), thus a more moderate temperature gradient is established within the ral atmosphere.
C isothermic level in the pacific appeared to rise from an average of 400 meters to about 100 meters recently; I find myself wondering then how is it that the oceans heat content is dropping, the solar input appears to be consistant, that one of the GEWEX comitties appears to indicate that the atmospheric water vapor seems to be decreasing.
The atmospheric Greenhouse Effect merely sets a theoretical background atmospheric temperature level that is continually overridden as a result of the size of the constant interlinked changes in both the solar and oceanic heat inputs.
We found that atmospheric brown clouds enhanced lower atmospheric solar heating by about 50 per cent.
In terms of magnitude of atmospheric heating effect, aborbed solar seems to rank a close second behind latent heating, in terms of net heating.
Could it be possible to get a heat retention double whammy wherein the atmospheric CO2 captures both first pass solar radiation from the sun and second pass bounceback radiation from the solar collectors?
If we continue emitting large amounts of CO2 while we work towards converting to 3/4 solar power and survive the heating that we inadvertently speed up by reflecting more heat into an atmosphere already overburdened with reflective - heat - capturing CO2, some day in the future when the atmospheric CO2 returns to its natural percentage of 0.0300 % instead of today's extremely high 0.03811 % the world will cool down to the levels that nature intended.
We do not need models to anticipate that significant rises in atmospheric CO2 concentrations harbor the potential to raise temperatures significantly (Fourier, 1824, Arrhenius, 1896), nor that the warming will cause more water to evaporate (confirmed by satellite data), nor that the additional water will further warm the climate, nor that this effect will be partially offset by latent heat release in the troposphere (the «lapse - rate feedback»), nor that greenhouse gas increases will warm the troposphere but cool the stratosphere, while increases in solar intensity will warm both — one can go on and on
In the heat - energy balance, which describes the gain or loss of heat in the system, sketched in figure 5, the solar and atmospheric radiation terms dominate.
The cryosphere derives its importance to the climate system from a variety of effects, including its high reflectivity (albedo) for solar radiation, its low thermal conductivity, its large thermal inertia, its potential for affecting ocean circulation (through exchange of freshwater and heat) and atmospheric circulation (through topographic changes), its large potential for affecting sea level (through growth and melt of land ice), and its potential for affecting greenhouse gases (through changes in permafrost)(Chapter 4).
Here are just some of the many benefits that these systems provide all at once: green infrastructure absorbs and sequesters atmospheric carbon dioxide (C02); filters air and water pollutants; stabilizes soil to prevent or reduce erosion; provides wildlife habitat; decreases solar heat gain; lowers the public cost of stormwater management infrastructure and provides flood control; and reduces energy usage through passive heating and cooling.
Other evidence [which I will present in future articles] seems to indicate that these same climate models are NOT realistically simulating such factors as atmospheric water vapour, clouds, solar energy fluctuations and cosmic ray effects, Earth's changing geomagnetic field, and Earth's interior heat with consequent surface heat variations.
The atmosphere is analogous to a flexible lens that is shaped by the density distribution of the gas molecules, of the atmosphere in the space between the sphere holding them, and space; Incoming heat gets collected in many ways and places,, primarily by intermittent solar radiation gets stored, in vast quantities, and slowly but also a barrage of mass and energy fluxes from all directions; that are slowly transported great distances and to higher altitudes mostly by oceanic and atmospheric mass flows.

The underlying global equilibrium temperature is set not by GHGs but by solar shortwave input to the oceans and atmospheric pressure (which sets the energy value of the latent heat of vaporisation).
weaker solar irradiance weaker solar wind increase in cosmic rays increase in volcanic activity decrease in ocean heat content a more meridional atmospheric circulation more La Ninas, less El Ninos cold Pdo / Amo
Since any increase in solar energy would heat both the lower and upper atmosphere, the observed drop in upper atmospheric temperatures in the past 30 years argues against an increase in energy coming from the sun being responsible for global warming.
For example, BC causes an increase in atmospheric heating, accompanied by a decrease in solar heating of the surface.
As I've previously pointed out the atmospheric greenhouse effect does not create heat, it merely delays the transmission of solar energy through the atmosphere.
Yet before writing tha book, Sorenson decided to go ahead and publish his 2011 article because, as he says, «Eunice Foote deserves credit for being the first to recognize that certain atmospheric gases, such as carbon dioxide would absorb solar radiation and generate heat... [three] years before Tyndall's research that is conventionally credited with this discovery.»
It is the combined effects of solar heating and greenhouse warming that establishes the atmospheric temperature structure and water vapor and cloud distribution.
Almost all climatologists work within a narrow slice of the total climatology pie: solar variations, the oceans, atmospheric circulation, heat transfer, cloud formation, proxies for past variability, climate models,... but very few if any, have a synoptic view of the entire field.
-- It seems perfectly reasonable to me that if we imagine the surface never emits that energy in the first place, - energy that is stored in the surface and just below, i.e. oceans, lakes, rivers, ground, and air, — just to mention a few, then any surface temperature change would be completely reliant on variations in Solar irradiation and advection mainly by Water Vapor (WV) but also by other GHGs that have the ability to contain more heat than the rest of the atmospheric gases.
However, it is likely that at night (when there is no incoming solar energy) or at other times when atmospheric conditions are such that there is a temperature inversion, any LWIR that has been delayed has sufficient opportunity to radiate to space there by meaning that no excess heat is «trapped» (ie., the heat in the atmosphere does not build up).

atmospheric absorption by CO2 and water vapor increases, reducing the solar heating at the surface, and surface evaporation increases faster with temperature than the transfer of sensible heat (due to the Clausius - Clapeyron relation), both of which tend to reduce the diurnal cycle.
Uranus is at the extreme end with a tilt of ~ 98 degrees; this would induce a very different structure of solar heating (where at certain times the North or South pole would be receiving most of the sunlight, and allow for a large migration of the solar «hotspot» over the course of one Uranian year); this should drive a different atmospheric circulation than on Earth.
