If you doubled CO2 and let the system come into equilibrium, the imbalance you'd measure from space would be zero — but there would still be about 4 W / m ** 2 of radiative forcing from the change in CO2.
As for your question about hurricanes, the argument given for the global mean hydrological cycle doesn't apply to the hurricane because the global mean argument assumes an equilibrium between radiative cooling and latent heat release.
Radiative equilibrium at small LW optical thickness occurs when the whole atmosphere has a temperature such that the Planck function is about half of that of the surface (a skin temperature), whereas at larger LW optical thicknesses, the equilibrium profile has a signficant drop in the Planck function through the atmosphere, approaching half the OLR value at TOA and approaching the surface value towards the surface — of course, convection near the surface will bring a closer match between surface and surface - air temperatures.
It might help Peter Huybers and his collegues if we understood more about the temperature response of the albedo of the calcite belt, and other bioogically variable components of radiative equilibrium that impact SST in both the southern ocean and the arctic seas
He found that convective equilibrium holds in the lower part of the troposphere up to about 10 Km, while radiative holds equilibrium above.
I should have probably written that explicitely in the post in order to avoid off topic discussions about radiative transfer or radiative equilibrium.
He cites Möller and Manabe (1961) for the statement that pure radiative equilibrium yields a temperature of about 350K.
Similarly, the climate scenarios were based on 2xCO2 equilibrium GCM projections from three models, where the radiative forcing of climate was interpreted as the combined concentrations of CO2 (555 ppm) and other greenhouse gases (contributing about 15 % of the change in forcing) equivalent to a doubling of CO2, assumed to occur in about 2060.
It is not the infrared emission that cools the surface as in the so - called radiative equilibrium models because the net radiative heat transfer surface to air is about nil, but the evaporation whose thermostatic effect can not be overstated: increasing the surface temperature by +1 °C increases the evaporation by 6 %; where evaporation is 100 W / m ², this removes an additional 6 W / m ² from the surface.
A 1 percentage point decrease in albedo (30 % to 29 %) would increase the black - body radiative equilibrium temperature about 1 °C, about equal to a doubling of atmospheric CO2.
Radiative equilibrium takes place on very fast (microsecond or less) timescales, so what on earth are you talking about?
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.
If an emissivity of about 0.87 is assigned to that Earth, the radiative - equilibrium temperature increases to about 288.7 K. Each of these base temperatures gives a different value for the zero - feedback sensitivity; 0.75 and 0.78, respectively.
