While ECS is the equilibrium global mean temperature change that eventually results from atmospheric CO2 doubling, the smaller TCR refers to the global mean temperature change that is realised at the time of CO2 doubling under an idealised scenario in which CO2 concentrations increase by 1 % yr — 1 (Cubasch et al., 2001; see also Section 8.6.2.1).

I do understand that the solar energy - in dictates the earthly energy - out at equilibrium at the balance point at the Top Of Atmosphere (~ 10,000 m) and that unless the solar - in changes then the law of conservation of energy requires that the Stefan - Boltzman derived 255 K temperature at equilibrium at this balance point can not change.

(Within the range where water vapor feedback is runaway, zero change in external forcing»cause s» a large change in climate; the equilibrium surface temperature, graphed over some measure of external forcing, takes a step at some particular value.)

Any discussion about not being at equilibrium yet (the usual response), fails to notice that on a daily basis the temperature varies by 10 - 15 degrees and that these changes will force the ground / atmosphere to get to equilibrium within a day or two.

«What relevance to a 5 % change in CO2, which at equilibrium would make a change in temperature of about.0.21 C at equilibrium based on a clmate sensitivity of 3C for doubling.»

What relevance does that have to a 5 % change in CO2, which at equilibrium would make a change in temperature of about.0.21 C at equilibrium based on a clmate sensitivity of 3C for doubling.

The alternative formula, that a change in temperature causes a change in dynamic equilibrium between CO2 release and CO2 absorption is far more normal in nature: higher temperatures lead to a new equilibrium at a higher CO2 level.

It is defined as the change in global mean surface temperature at equilibrium that is caused by a doubling of the atmospheric CO2 concentration.

At the end of a climatic shift, the temperature setup of the entire planet will have changed — so far until a new equilibrium energy budget is reached.

I will howl at you that you can't tell me the glass of water has reached an equilibrium with the ambient environment because the ambient temperature is inhomogeneous and always changing.

So, a system at Local Thermodynamic Equilibrium doesn't change temperature.

While ECS is the equilibrium global mean temperature change that eventually results from atmospheric CO2 doubling, the smaller TCR refers to the global mean temperature change that is realised at the time of CO2 doubling under an idealised scenario in which CO2 concentrations increase by 1 % yr — 1 (Cubasch et al., 2001; see also Section 8.6.2.1).

If a black body with a fixed - rate energy source is in radiation - rate - equilibrium with the vacuum of space at 0 Kelvins, placing additional material separate from but surrounding the black body will likely cause the temperature of the surface of the black body to change in such a way that energy - rate - equilibrium is re-established for the black body.

The temperature at various locations in the atmosphere and on the surface of the earth is determined by the net flux of energy at that location (and never reaches true equilibrium because the energy input from the sun changes with night / day and the seasons).

If local thermodynamic equilibrium exists in a certain volume of a gas, and you add more CO2 at the same temperature, it is true that the volume's temperature will not change.

But given the time constants for heating (or cooling) the oceans, there's at least a half - century time lag between a large change in forcing and a final temperature equilibrium.

The Lewis and Curry paper said the best estimate for equilibrium climate sensitivity — the change in global mean surface temperature at equilibrium that is caused by a doubling of the atmospheric CO2 concentration — was 1.64 degrees.

But that isn't an ECS calculation, it's somewhere between TCR and ECS, which is where we're always going to be when CO2 is changing at a clip faster than thermal inertia of the oceans allows an equilibrium temperature response.

I agree that reduction in snow or ice cover resulting from warming constitutes a likely slow positive feedback, but its magnitude may be quite small, at least for the modest changes in surface temperature that can be expected to arise if sensitivity is in fact fairly low, so the Forster / Gregory 06 results may nevertheless be a close approximation to a measurement of equilibrium climate sensitivity.

Pekka, I don't think you are disputing that in an adiabatic convective profile, the temperature at higher altitudes is colder, so the higher molecules are slower, and are continually moving up and down without losing or gaining diabatic energy but with their temperature changing, so I think this argument is about whether the convective profile is an equilibrium profile or not.

where ΔT represents the change in the equilibrium temperature, C represents the CO2 level and Co represents the CO2 level at which ΔT is nil.

With the ocean surface at equilibrium, if DLR is increased by 10W / m ^ 2, the surface temperature changes by T», the latent heat flux increases by L', the convected heat from below the top layer changes by C» and the radiated heat changes by R»..

Changing global temperatures induce air circulation changes as the air seeks to restore the sea surface / surface air temperature equilibrium and at the same time resolve ocean induced variations in the sun to sea / air to space equilibrium.

By dividing the total temperature change (as indicated by the best - fit linear trend) by the observed rise in atmospheric carbon dioxide content, and then applying that relationship to a doubling of the carbon dioxide content, Loehle arrives at an estimate of the earth's transient climate sensitivity — transient, in the sense that at the time of CO2 doubling, the earth has yet to reach a state of equilibrium and some warming is still to come.

At some stage, the temperature of the earth ocean system will be at equilibrium (if we stop changing the forcing after 30 years and then wait a long timeAt some stage, the temperature of the earth ocean system will be at equilibrium (if we stop changing the forcing after 30 years and then wait a long timeat equilibrium (if we stop changing the forcing after 30 years and then wait a long time).

If you think of the system as being in steady - state, at least approximately, instead of equilibrium; and if you think of the effect of CO2 increase to be a change from one steady - state to another, it would not necessarily be the case that the temperature increase of the surface, middle troposphere, and upper troposphere to be the same.

At minimum, the surface, mid-troposphere and upper troposphere are never in equilibrium, but are continually changing total energy content and temperature.

The IPCC defines radiative forcing as «the change in net (down minus up) irradiance (solar plus longwave; in W m — 2) at the tropopause after allowing for stratospheric temperatures to readjust to radiative equilibrium, but with surface and tropospheric temperatures and state held fixed at the unperturbed values».
