This piece will have echoes from my recent piece The Bane

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in
equilibrium with water / ice, would precipitate
out if not
for the CO2, so acts as a feedback; since the oceans cover so much
of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces
for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration
of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices
for disk drives — hows that
for unexpected adverse impacts from AGW?)

of anthropogenic CO2 releases that have been taken
out of the atmosphere (over and above the amount taken
out of the atmosphere that balances the natural additions to the atmosphere), perhaps mainly as a direct biogeochemical feedback (increased CO2 favoring more rapid biological fixation
of C, net flux
of CO2 into water until
equilibrium for the given storage
of other involved chemical species in the upper ocean) fairly promptly.
This leads to a higher
equilibrium temperature, but balance is reestablished again in a sense that time averages
of energy in - and -
out are equal
for each volume element, given some fixed elevation
of greenhouse gas concentration.
In
equilibrium, all fluxes into the surface will be balanced by fluxes
out of the surface (including momentum, etc, as well as energy), so whatever lies beneath the surface gives the surface an effective heat capacity and also (in the oceans) some ability
for local / regional imbalances to be balanced globally, with all
of that responding to forcings and PR+CR and other feedbacks at the surface.
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).
The effect it has on the
equilibrium sensitivity is more indirect, as the more the ocean can buffer excess heat, the more chance it will give
for CO2 to sequester
out of the system.
For those who want to check
out the physics, read up the statistical thermodynamics which leads to Kirchhoff; s law
of radiation and realise that «Prevost exchange energy» is needed to connect the IR density
of states in the two objects in radiative
equilibrium and maintain absorptivity = emissivity.
The result turned
out to be precisely a sawtooth, which struck me as both a simple way
of accounting
for this three - way coincidence (frequency, amplitude, and phase) and one that (as Greg himself has pointed
out) naturally occurs in geophysics as a result
of sudden events perturbing
equilibrium followed a return to
equilibrium that may be far from complete when the next such event occurs.
With regard to the diabatic process the exchange
of radiation in and
out reaches thermal
equilibrium relatively quickly (leaving Earth's oceans
out of the scenario
for current purposes) and once the temperature rise within the atmosphere has occurred then
equilibrium has been achieved and energy in at TOA will match energy
out.
The planet reaches an essential
equilibrium during these periods in that it reaches a certain temperature range
for 10,000 or 20,000 years and does not continue the warming it did to rise
out of the glacial period.
The main point is that
for a spherical body in radiative thermal
equilibrium with the sun, where absorptivity = emissivity, then the temperature is independent
of albedo and emissivity, because they cancel
out of the equation.
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.
In spite
of the fact that the top post derives the explicit form
for an ideal gas in hydrostatic and thermal
equilibrium, I might point
out.
It is just a proxy
for heat conduction, something that he seems to have left
out of consideration when he listed the agents responsible
for establishing thermal
equilibrium in his «thought experiment».
Actually, the relevant «law» is not the ever rising entropic «heat death»
of the universe from CO2, but instead is Le Châtelier's principle
for a reaction in physical chemistry: the disturbance
of the
equilibrium of greenhouse gases H2O and CO2 by CO2 injections acts to oppose the change to the
equilibrium, and thus to cancel
out the effect on temperature from the increase in CO2.
As Joshua Gans points
out here The Russell Girl divx the effect
of the scheme will be to reduce the demand
for permits and therefore the
equilibrium price.
If it can not warm the oceans and yet the radiative balance between solar energy in and radiative energy
out has to be maintained then all that is left is
for it to be ejected faster to space in order to maintain the radiative balance and if that happens then no change in the
equilibrium temperature
of the Earth can occur.
QUOTE: «As shown on figure 17 - D the regions

out - gassing are separate; there is no «global»

of knowledge
of dynamic systems here: as long as the total
of the CO2 influxes is the same as the total
of the CO2 outfluxes, nothing happens in the atmosphere.

Therefore, estimating
equilibrium climate sensitivity based on measurements
of a climate that's
out of equilibrium requires making some significant assumptions,
for example that feedbacks will remain constant over time.
If we begin
out of equilibrium, with a net natural flux outward
of whatever magnitude and
for whatever reason (as Salby might suggest), that means that ocean pCO2 exceeds that
of the air.
If our use
of the IPCC's own predictions
of future CO2 growth on the A2 scenario, and its own equation
for converting those predictions to
equilibrium temperature, leads to predictions
of temperature response that are different from those
of the IPCC, then it may be that we are doing the sums wrong, in which case a true scientist would point
out what we are doing wrong.
