One of his views that always stuck with me on that subject, at least as a starting point for thinking about it, was that it was somewhat nonsensical to talk about what «equilibrium exchange rates» should be in a world of fiat currencies and fractional reserve banking.

It is also important to note that at the beginning of the current boom, the unemployment rate was around 6 per cent, suggesting that there was some excess capacity in the labour market at the outset of the adjustment to the mining investment boom (this is another point of departure from the theory presented in Section 2, which assumes that the economy is in equilibrium prior to the boom).

And here we can see with complete clarity the importance of the idea, suggested above, that it is at its point or superstructure of spiritual concentration and not at its base or infrastructure of material arrangement that humanity must biologically establish its equilibrium.

Whatever our assessment of that point of equilibrium may be, we can not lose sight of why Tocqueville thought a social state that at once recognized difference and similarity had such appeal.

The process of separation, transition, and reintegration occurs in terms of the disruption of a steady state at or near equilibrium, which brings matter increasingly far from equilibrium to a point at which a «decision» is made between alternative possibilities randomly presented by its environment, resulting in its reorganization in novel emergent form.

The «equilibrium» sensitivity of the global surface temperature to solar irradiance variations, which is calculated simply by dividing the absolute temperature on the earth's surface (288K) by the solar constant (1365Wm - 2), is based on the assumption that the climate response is linear in the whole temperature band starting at the zero point.

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.

Added to this is the reality that the atmosphere returns to equilibrium at least twice every day since in its daily warming and cooling every point on earth goes from absorbing energy in the day to expelling energy at night, passing through equilibrium in the process.

Question: before talking about simulating climate CHANGE, how long does the climate science community expect it to take before GCM's can reproduce the real world climate PRIOR to human induced CO2 perturbation in terms of: — «equilibrium point», i.e. without artificial flux adjustment to avoid climatic drift, — «natural variability», in terms of, for instance, the Hurst coefficient at different locations on the planet?

At the point where there is so much H2O vapor in the atmosphere that there is very little solar heating of the surface (very very far from happenning), there will also tend to be almost no net LW cooling at the surface, so a tropospheric - type lapse rate could still tend to extend down to the surface (as long as the net LW cooling is smaller than the SW heating, there will be some non-radiative flux from the surface for equilibrium conditionsAt the point where there is so much H2O vapor in the atmosphere that there is very little solar heating of the surface (very very far from happenning), there will also tend to be almost no net LW cooling at the surface, so a tropospheric - type lapse rate could still tend to extend down to the surface (as long as the net LW cooling is smaller than the SW heating, there will be some non-radiative flux from the surface for equilibrium conditionsat the surface, so a tropospheric - type lapse rate could still tend to extend down to the surface (as long as the net LW cooling is smaller than the SW heating, there will be some non-radiative flux from the surface for equilibrium conditions).

I should point out that Kirchhoff's Law only applies at a given wavelength, and for a body in local thermal equilibrium.

For example, if the Earth got cold enough, the encroachment of snow and ice toward low latitudes (where they have more sunlight to reflect per unit area), depending on the meridional temperature gradient, could become a runaway feedback — any little forcing that causes some cooling will cause an expansion of snow and ice toward lower latitudes sufficient to cause so much cooling that the process never reaches a new equilibrium — until the snow and ice reach the equator from both sides, at which point there is no more area for snow and ice to expand into.

What could hypothetically happen if a very large change in GHG amount / type is made, is that the forcing could increase beyond a point where it becomes saturated at the tropopause level at all wavelengths — what can happen then is that the equilibrium climate sensitivity to the nearly zero forcing from additional GHGs may approach infinity, because in equilibrium the tropopause has to shift upward enough to reach a level where there can be some net LW flux up through it.

Once the ice reaches the equator, the equilibrium climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to climate changes, but this is generally very slow, and thus can not prevent faster changes from faster external forcings) enough, it can initiate melting — what happens then is a runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).

A sharp change in lapse rate will (absent sharp changes in optical thickness per unit distance, which occurs at TOA and at the surface even in wavelength bands dominated by well - mixed gases) tend to differ from radiative equilibrium — the inflection point may correspond to a maximum deviation from radiative equilibrium if the radiative equilibrium profile has some intermediate lapse rate in that vicinity.

I agree with Maxwell's point that at equilibrium two bodies they exchange equal amounts of thermal radiation with each other.

The terrestrial biosphere can respond slowly to large, regional - scale forcing, but may not always be in equilibrium with that forcing at any point in time, leading to subsequent commitments to significant future change for decades or centuries following stabilization of forcing.»

As the system approaches equilibrium, entropy would become constant at the steady state value for the condition of the system., which would be maximum entropy or minimum depending on your point of view.

In point of fact it's physically impossible for the entire earth to ever be more than 10C everywhere at equilibrium as that would have it emitting more power than it receives from the sun which would violate conservation.

Much as a drop of dye in a set of connected containers will diffuse between them until reaching some equilibrium concentration, at rates dependent upon exchange rates, bomb - spiked C14 CO2 will reduce its level in the atmosphere at a fairly quick rate, replaced by other isotopes in relation to their concentration, because quite frankly there is more C14 at the spike point (atmosphere) than in the oceans.

This behavior is characteristic of an unchanging (at least in short terms of centuries) natural equilibrium point for CO2 around 280ppm (interglacial - normal).

Sorry Mike, but as I pointed out above, you're ignoring the fast - equilibrium of Henry's law, which sets a fixed partitioning ratio of 1:50 for how much CO2 resides in the atmosphere and oceans respectively at the current mean surface temperature of 15C.

But I think that misses the point; if you've got a hollow sphere, filled with a mixed gas at equilibrium at a certain temperature, and then you replace some of the gas with CO2 (raise the concentration) does the sphere necessarily retain more heat?

I have at this point presented a solution to Jelbring's problem that is manifestly isothermal, is manifestly in hydrostatic equilibrium, is manifestly a maximum entropy state.
