A positive net trend
in radiant flux at TOA is defined as planetary warming.
The change in heat and work in the planetary system is made complicated by large changes
in radiant flux at TOA due to changes in atmospheric and ocean circulation (Loeb et al 2012).
The difference
in radiant flux will be smaller between 222 K and 255 K, and larger between 288 K and 321 K, and it will take a greater GHE TOA forcing to reduce the effective radiating temperature (the temperature of a blackbody that would emit a radiative flux) at TOA from 288 K to 277 K as it would to reduce it from 277 K to 266 K, etc..

The figure of Don Juan is an imaginative impossibility
in our time because he comes from a period
in which the human being was understood not merely as a biological machine, generated randomly out of the incessant
flux of an aleatory universe, but as a
radiant and terrible enigma, dangerously and daringly poised between beast and angel, hell and heaven, the elemental abyss and the infinite God: a period
in which it was still just possible to believe that human freedom was not merely the all - but - illusory residue of a random confluence of mindless physical forces and organic mechanisms, but a glimpse of the transcendent within the world of matter.

Refraction, specifically the real component of refraction n (describes bending of rays, wavelength changes relative to a vacuum, affects blackbody
fluxes and intensities — as opposed to the imaginary component, which is related to absorption and emission) is relatively unimportant to shaping
radiant fluxes through the atmosphere on Earth (except on the small scale processes where it (along with difraction, reflection) gives rise to scattering, particularly of solar radiation —
in that case, the effect on the larger scale can be described by scattering properties, the emergent behavior).
The skin layer planet is optically very thin, so it doesn't affect the OLR significantly, but (absent direct solar heating) the little bit of the
radiant flux (approximatly equal to the OLR) from below that it absorbs must be (at equilibrium) balanced by emission, which will be both downward and upward, so the
flux emitted
in either direction is only half of what was absorbed from below; via Kirchhoff's Law, the temperature must be smaller than the brightness temperature of the OLR (for a grey gas, Tskin ^ 4 ~ = (Te ^ 4) / 2, where Te is the effective radiating temperature for the planet, equal to the brightness temperature of the OLR — *** HOWEVER, see below ***).
When optical thickness is large, the net
flux will tend to be small, but the
flux will vary with lapse rate (according to the corresponding Planck function «lapse rate») and a sufficiently sharp change
in that lapse rate could lead to some significant
flux convergence or divergence at that level (net
radiant heating or cooling).
Synoptic scale forcing (e.g., wind bursts) were found to lead to tripling of phytoplankton pigment concentrations and a reduction
in penetrative heat
flux of 5.6 W m − 2 at 30 m, or a biogeochemically mediated increase
in the
radiant heating rate of 0.138 C / month.
Oceans gained energy to 1998 — pretty much
in line with changes
in ERBS net
radiant flux.
OHC follows changes
in TOA
radiant flux as shown
in the Wong et al 2006 paper — ocean / atmosphere heat transfer obviously occurs but the fundamental metric is at TOA.
We are not interested
in temperature here — but directly
in the measurements of
radiant flux in various wavelengths.
The planetary heat content — and therefore OHC — must follow the changes
in TOA
radiant flux by the first law of thermodynamics.
Greenhouse gas forcing can not be seen
in top of atmosphere

Energy

CERES anomalies provide a new precision

The change
in average
radiant flux at the surface is too little to be more than a small part of the puzzle.
Instead, it gives

The fundamental equation of radiative transfer at the emitting surface of an astronomical body, relating changes
in radiant - energy
flux to changes
in temperature, is the Stefan - Boltzmann equation --
However, the IPCC,
in its evaluation of κ, does not follow the rule that
in the Stefan - Boltzmann equation the temperature and
radiant - energy
flux must be taken at the same level of the atmosphere.
