These include the family of so - called exercise pills, drugs designed to boost the rate at which bodies burn fat and dissipate the energy as heat — an effect that would provide many of the benefits of regular mild exercise.
Successful reshaping can only occur within a narrow window of the heat dissipation rate: Low cooling rates lead to drastic morphological changes, and fast cooling has nearly no effect.
Rotational disruption is the expected final state of what is called the YORP effect — a slow evolution of the rotation rate due to asymmetric emission of heat.

An additional issue of outdoor enclosures can also be the aptly - named greenhouse effect, a consequence of not using bonded panels, whereby the air trapped between the display panel and overlay will under sun exposure heat at a much faster rate than usual.
Heat therapy effects includes improved circulation to tissues, increased in the rate of enzymatic and biochemical reactions to facilitate healing, and prior to stretching, allows greater extensibility of tissues during range of motion therapies.
If the atmosphere consisted of Oxygen / Nitrogen only, its thermal conductivity would be very low, solar heating would be much the same, and the insulation effect (and the gravitational lapse rate) would produce a substantial temperature differential from the surface to the top of the atmosphere without any radiative absorption.
Gasses conduct heat between two plates of glass at a rate proportional to the speed of the gas, and less efficiently with greater distance between the plates [the effect also varies in different pressure regimes, it is very efficient at low vaccuum, because gas molecules can travel from plate to plate without being intercepted.
You argue that this «slowdown» is evidence against the truth that an increased greenhouse gas effect slows down the rate of heat flowing out of the planetary system and thus increases the total heat in the system.
The essence of the greenhouse effect is that the atmosphere inhibits energy loss (to space) so that for a given rate of solar energy input, the temperature of the surface has to be greater in order to allow the necessary amount of heat to be lost per unit time.
Re # 173 (Dan Allan): Large - scale reasons for the chaos include planetary tilt (= seasons), a high rate of rotation (= major Coriolis effect), much more solar heat applied at the equator than at the poles, unevenly distributed land, air and water, a molten core resulting in tectonic activity including continental drift and volcanos, the occasional hammer from space, a really large satellite creating major tides in addition to minor ones from the sun, plus some stuff I'm probably forgetting.
The upper part of the ozone layer contributes to net LW cooling there — of course, this includes the effect of solar heating on the stratospheric lapse rate.
Re my 441 — competing bands — To clarify, the absorption of each band adds to a warming effect of the surface + troposphere; given those temperatures, there are different equilibrium profiles of the stratosphere (and different radiative heating and cooling rates in the troposphere, etc.) for different amounts of absorption at different wavelengths; the bands with absorption «pull» on the temperature profile toward their equilibria; disequilibrium at individual bands is balanced over the whole spectrum (with zero net LW cooling, or net LW cooling that balances convective and solar heating).
Similar negative effects occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).
The only process that one could argue is minimally effected by CO2 is — the RATE of heat transfer from the Earth's surface — but with convective / conductive energy / mass transfer as the controlling mechanism — it would be immediately acted on by increased convection anyway — because Earth isn't surrounded by a glass bowl now is it — NO — just the cold depths of space!
Factors that resulted in a net cooling or a net effect close to zero aren't really relevant, nor are climate dynamics that affect the rate of warming as a function of ocean heat uptake, since that does not significantly affect the apportionment of warming among different factors.
Disputes within climate science concern the nature and magnitude of feedback processes involving clouds and water vapor, uncertainties about the rate at which the oceans take up heat and carbon dioxide, the effects of air pollution, and the nature and importance of climate change effects such as rising sea level, increasing acidity of the ocean, and the incidence of weather hazards such as floods, droughts, storms, and heat waves.
Combining the greater share of weather stations in more urban areas over time with this urban heat effect also tends to increase the rate that recorded temperatures tend to rise over time.
The Arctic has been warming at twice the rate of the rest of the world for decades because of feedback loops that have reduced the albedo effect, a measure of the way Earth reflects heat.
For example, the CLOUD experiments could provide insights into the rate of tropical cloud formations which effect tropical cooling and the heat transfer from the tropics to the higher latitudes.
The specific heat of water vapour is higher than that of carbon dioxide, so it will reduce the gradient slightly, and thus have a cooling effect, just as it does by reducing the gradient to the «wet adiabatic lapse rate» on Earth.
And another thing, when we look at the past 100 + years of temperature change, even when we have to try to peer through grossly mis - adjusted warmist data and a growing urban heat island effect, we see little discernible changes in the rate of early 20th century (low CO2) and later 20th century (higher CO2) change.
The best papers I've read (so far) that seek to explain how things like the DALR and wet air lapse rates effect the actual transport of heat from the solar - heated surface and atmosphere to where it is ultimately lost via radiation are really quite good.
Even extending to pre-Argo periods, with a long period the errors in ocean heat content values have to be very large to have a major effect on the mean rate of heat uptake over the period.
Even aside from that, the greenhouse effect theory makes fairly specific theoretical predictions about how the rates of «infrared cooling» and «ozone heating» are supposed to vary with height, latitude, and season, e.g., Figures 8 and 9.
As said on cards n ° 1, n ° 6 and n ° 15, for an atmosphere in a gravitation field, the tropospheric lapse rate is dT / dz = — g / (Cp + Ch) where g = 9,8 m / s ², Cp = 1005 J / kg, and Ch summarizes the effect of the heating of the air (1) by absorption of the solar infrared by water vapour or liquid and (2) by the condensation of the water vapour.
This figure indicates 3 things: (1) the time lag between emitting greenhouse gases and when we see the principle effect is about 30 years, due mostly to the time required to heat the oceans, (2) the rate of temperature increase predicted by a climate sensitivity of 3 °C tracks well with the observed rate of temperature increase, and (3) we have already locked in more than 1.5 °C warming.
This essentially is a moderating effect, and does not seem to be dependent on re-radiation of IR trapping greenhouse gases in anyway, except to the extent that it slows the rate of heat loss at night (which may very well be a real — albiet a small — effect).
The greenhouse effect and a real greenhouse are similar in that they both limit the rate of thermal energy flowing out of the system, but the mechanisms by which heat is retained are different.
However, as the water vapor rises the lapse rate means that the volume of air cools and eventually the water vapor condenses into water droplets and then into ice latent heat is given off to the surrounding air at each of these phase changes, with two effects.
Vincentrj # 28 you are unclear re the division of your opinions / inferences between the 3 basic sub-topics (1) heat is entering the oceans due to radiative imbalance due to humans burning carbon fuels (2) the heat rate coupled with its estimated duration (based on its cause) will make it within a few decades become unprecedented during the last several thousand years and same for the surface temperature rise that will be required to stop it (3) the effects on flora & fauna will be highly negative even within this century and more so for centuries and millenia thereafter, in particular the human species which has softened much and expects much more since the days when a mammoth tusk through the groin was met with «well Og's had it, press on».
The basic results of this climate model analysis are that: (1) it is increase in atmospheric CO2 (and the other minor non-condensing greenhouse gases) that control the greenhouse warming of the climate system; (2) water vapor and clouds are feedback effects that magnify the strength of the greenhouse effect due to the non-condensing greenhouse gases by about a factor of three; (3) the large heat capacity of the ocean and the rate of heat transport into the ocean sets the time scale for the climate system to approach energy balance equilibrium.
I see discussion of ocean temperature and evaporation rates without mention of relative humidity effecting evaporation and heat content.
However, the laplse rate has ABSOLUTELY NOTHING to do with greenhouse effects, being dependent upon only the heat capacity of the air (Cp) and gravity (g).
jae, your statement that the lapse rate has ABSOLUTELY NOTHING to do with greenhouse effects, being dependent upon only the heat capacity of the air (Cp) and gravity (g).
The fact that no hot spot has develped suggests that the effects of GHG are to increase the vertical convection rate, increasing the rate at which heat is returned to space.
[Response: Your argument misses the point in three different and important ways, not even considering whether or not the Black Hills data have any general applicability elsewhere, which they may or may not: (1) It ignores the point made in the post about the potential effect of previous, seasonal warming on the magnitude of an extreme event in mid summer to early fall, due to things like (especially) a depletion in soil moisture and consequent accumulation of degree days, (2) it ignores that biological sensitivity is far FAR greater during the warm season than the cold season for a whole number of crucial variables ranging from respiration and photosynthesis to transpiration rates, and (3) it ignores the potential for derivative effects, particularly fire and smoke, in radically increasing the local temperature effects of the heat wave.
Lolwot or m. Carey would be quite right to point the well known physics meaning increasing GHG will have the effect of slowing the rate heat escapes.
We assume that Chylek (2008) is right to find transient and equilibrium climate sensitivity near - identical; that allof the warming from 1980 - 2005 was anthropogenic; that the IPCC's values for forcings and feedbacks are correct; and, in line 2, that McKitrick is right that the insufficiently - corrected heat - island effect of rapid urbanization since 1980 has artificially doubled the true rate of temperature increase in the major global datasets.
Taking everything into consideration, if the AGWers think that some «backradiation» from the CO2 we have here is going to have any effect whatsoever, especially net effect, on the RATE of heat loss from the earth, they must be totally barmey.
The second issue is far more complex, namely the inter-relationship with other gases in the atmosphere and what effect it may have on the rate of convection at various altitudes and / or whether convection effectively outstrips any «heat trapping» effect of CO2 carrying the warmer air away and upwards to the upper atmosphere where the «heat» is radiated to space.
You say «But the greenhouse effect according to climate «science» is not the insulation of a blanket or a reduction in the rate of cooling, but a positive addition of heat (33C or more) because of «backradiation».
