Question should have been: What is the equilibrium temperature of a body that absorbs 100W initially starting at 100K?
The real travesty in climate science is that the ubiquitously accepted null hypothesis is that the earth's spectrum without the greenhouse effect of the atmosphere (ie, its surface spectrum) is approximately that of sort of a step function with an (observed) albedo of approximately 0.3 with respect to the sun's spectrum but 0.0 with respect to the approximately 279 kelvin temperature of a gray (flat spectrum) ball in our orbit thus producing equilibrium temperature of about 255 kelvin.

An albedo decrease of only 1 %, bringing the Earth's albedo from 30 % to 29 %, would cause an increase in the black - body radiative equilibrium temperature of about 1 °C, a highly significant value, roughly equivalent to the direct radiative effect of a doubling of the atmospheric CO2 concentration.

The point is, if DLR only goes into evaporation then what will be the equilibrium temperature of the ocean.
Thus DLR in any quantity or from any source can not alter the equilibrium temperature of the oceans.
More DLR therefore fails to achieve a net slowdown in energy throughput and the equilibrium temperature of the subskin and bulk ocean fails to rise despite the rise in temperature of the ocean skin.
So the existing pressure regime permits changes in the rate of energy flow independently of temperature such that the warmer skin does not change the equilibrium temperature of the ocean bulk.
The equilibrium temperature of the system only changes if you change the temperature of the ocean bulk.

4) If WV stayed the same on a planet entirely covered by land and all else being equal the equilibrium temperature of that planet would be much less than that of Earth because the faster response time in warming up from solar energy would be matched by an equally fast loss of energy at night and in winter.
6) Consider now the effect on the equilibrium temperature of the entire oven by a tiny change in the conductive characteristics of the air within it.
3) The slowing down effect in the oceans is so huge that it renders the slowing down effect in the air insignificant so that the equilibrium temperature of the planet is set by the oceans and not the air.
It is the slowing down of the transmission of solar energy through the entire planetary system of Earth that sets the equilibrium temperature of the planet.
6) The oceans are a charged battery that sets and maintains the equilibrium temperature of the planet with the greenhouse effect in the air an insignificant player.
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.
Given that the blackbody equilibrium temperature of earth as seen from space is a function of solar irradiance arriving and earth albedo and not much of anything else apart from factors that change those two, anyone claiming earth's temperature isn't affected by solar output better have a pretty good theory and data to support that.
In case you don't know, the subsolar temperature is the equilibrium temperature of a 1 square metre patch, facing the star, on the equator of a non-rotation body.
Bryan: The basic law of radiation heat transfer which denotes that the equilibrium temperature of a black body surface varies as the fourth root of the radiative energy it emits?
Does the atmospheric pressure, no GH gases, effect the overall equilibrium temperature of the near surface of a planet?
Of all the linear temperature profiles, find entropy maximization requires the equilibrium temperature of Fig. 1 to decrease with increasing height i.e. it is non-isothermal, T1b is required to be higher than T1t by proper maximization of entropy.
In the case of the Earth, the solar irradiance of 1,368 W / m ^ 2 has a Stefan Boltzmann black body equilibrium temperature of 394 K, 121 C, 250 F. That's hot.
The Earth's albedo reflects away about 30 % of the Sun's 1,368 W / m ^ 2 energy leaving 70 % or 958 W / m ^ 2 to «warm» the surface (1.5 m above ground) and at an S - B BB equilibrium temperature of 361 K, 33 C cooler (394 - 361) than the earth with no atmosphere or albedo.
That is why established science does not list the radiative features of constituent gases as one of the factors that influence the equilibrium temperature of planets with atmospheres.
While the real atmosphere is not beset by giant electrical coils, it does (in theory) have infrared emitters (GHGs) which alter the equilibrium temperature of the ocean surface, so the thought experiment is enough to show that the line of reasoning you presented is unphysical.
Atmospheric CO2 is indeed the principal LW control knob that governs the global equilibrium temperature of Earth.
During that process, upward LW radiation reaching the upper atmosphere will increase (depending on albedo / solar heating feedbacks), which will change the equilibrium temperature of the upper atmopshere again.
BA: So you do agree to my definition of «gray» as «flat spectrum» and do agree that the equilibrium temperature of a gray body is the same as a black.
The planet receives an insolation flux of $ \ sim 8 \ times 10 ^ 9 ~ -LCB- \ rm erg ~ s ^ -LCB--1 -RCB- ~ cm ^ -LCB--2 -RCB--RCB- $, implying an equilibrium temperature of of ~ 2250 K, assuming zero albedo and complete heat redistribution.
Recently observations of the light reflected by these planets provided insight on the cloud distribution on the dayside of these planets: for a handful of planets clouds seem more abundant on the western than on the eastern side of the dayside hemisphere and, more importantly, this asymmetry depends on the equilibrium temperature of the planet.
We then reassess the radii and equilibrium temperatures of known and candidate planets based on our spectroscopically derived stellar parameters.

Setting each of the qubits in its own heat bath, each at a different temperature, throws the system out of equilibrium.
Using global climate models and NASA satellite observations of Earth's energy budget from the last 15 years, the study finds that a warming Earth is able to restore its temperature equilibrium through complex and seemingly paradoxical changes in the atmosphere and the way radiative heat is transported.
«This emphasizes the importance of large - scale energy transport and atmospheric circulation changes in restoring Earth's global temperature equilibrium after a natural, unforced warming event,» Li said.
There's just one catch: The material must be «in equilibrium,» meaning that any particle motions must be due to the effect of the material's temperature rather than any external forces acting on the particles.

The idea of climate inertia is that when you increase the CO2 concentration in the atmosphere it takes the climate system a good deal of time for all its components to fully adjust and reach a new equilibrium temperature.
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.
However, there is an additional shortcoming due to the fact that the equilibrium temperature is also affected by the ratio of the Earth's geometrical cross-section to its surface area as well as how much is reflected, the planetary albedo (A).
Recent attempts to understand cloud formation have explored wide regions of the equilibrium temperature - gravity parameter space.
