The variability of the total or
planetary heat transport (PHT) is much smaller than the variability in either AHT or OHT alone, a feature referred to as «Bjerknes» compensation».
It will therefore no longer represent the depth from which
the planetary heat loss takes place.
However, it has long been established that the bulk
planetary heat loss is determined by atmospheric temperatures far above the surface (Hulburt 1931; North 1975).
Convection can therefore compensate for reduced radiative transfer if its mean vertical extent reaches the height of
the planetary heat loss.
The planetary heat loss would drop if the emission temperature were to drop, and the planet would no longer be in energy balance, resulting in energy accumulation.
Not enough is yet known about the other
planetary heat storage and transfer mechanisms that act with TSI or against TSI to make the switch.
Both greenhouse gases further turn up
the planetary heat, cause more permafrost to melt, and create a terrible feedback loop of ever - worsening climate change.»
Moreover, we have known since the mid-nineteenth century that CO2 absorbs infrared radiation and thus acts as a greenhouse gas which impedes
planetary heat loss and thus warms up the surface.
• Science is predictive
The planetary heat budget will be imbalanced, such that the seas will warm and rise.

The planetary heat content — and therefore OHC — must follow the changes in TOA radiant flux by the first law of thermodynamics.
And yet the seas have kept on rising, and the polar ice hs kept on melting, and
planetary heat - records keep on breaking
The last time the CO2 level was this high the continental configuration was different and
the planetary heat flows were significantly different.
There were no scientific claims of catastrophe UNLESS we do nothing and continue to emit GHGs (and therefore increase
planetary heat retention) like there is not even an issue.
Additionally the oceanic warming and cooling cycles introduce constant, rapid and substantial changes not yet reflected in any models and which invalidate any averaged global estimates of
the planetary heat budget.
A short while ago I published an article attempting to explain why the so called atmospheric greenhouse effect was insignificant as
a planetary heat store in comparison to the oceans.
The newest paper, in the current issue of Science, «Varying
planetary heat sink led to global - warming slowdown and acceleration,» argues that the Atlantic not only has shaped the current plateau, but also was responsible for half of the sharp global warming at the end of the 20th century.
Would it not be better to focus on
planetary heat fluxes?
The optical depth dictates how deep into the planet's atmosphere the origin is for most of the planet's infra - red light (the main
planetary heat loss) that can be seen from space.
The calculations estimate the reduction in the energy flux density with distance away from the sun (Gauss» theorem) and the black body radiation describing the rate of
planetary heat loss.
«The transition from solar maximum to solar minimum probably also contributed a small part as
planetary heat absorption decreased by about 15 %.»
i.e. converting some to mechanical energy in the form of storms and moving more to
the planetary heat sinks of the poles and deeper water.
Partly as an addendum to comment # 1, I'd like to hear if anyone knows of any research which attempts to quantify the likely change to
the planetary heat balance in a zero summer sea ice scenario, such as we may see well before 2040.
The second step involved calculating Earth's energy balance for this time period, using estimates of greenhouse gas concentrations extracted from air bubbles in ice cores, and incorporating astronomical factors, known as Milankovitch Cycles, that effect
the planetary heat budget.
In the case of Earth, there's another 6300 kilometers of rock and iron beneath the tectonic plates whose churnings constitute the inner workings of
a planetary heat engine.
If enough forests collapse, the flame on
the planetary heating element could turn from «low» to «high.»
I have to agree with Mike — 20; the need is for action based on the lessons learned from Nature's response to
planetary heating.
As scientists say, there is a «major gap» in our understanding» of
planetary heating and cooling... and it has not been bridged by greenhouse gases hypotheses.
IF ongoing
planetary heating from CO2 back - radiation is continuing but being hidden a-la-Trenberth in the oceans, then this ocean heat would be visible as an increase in sea level rise.
In their attempt to create the illusion of ferocious winter weather on a rapidly warming planet, the geoengineers are actually further fueling the overall
planetary heating.

planetary collision that formed the moon hit the asteroid belt 4.47 billion years ago.
Asteroid impacts did
heat the subsurface, according to the simulations, but even the heaviest bombardment scenarios were not intense enough to sterilize the planet, the researchers report March 1 in Earth and
Planetary Science Letters.
The third process, tidal dissipation, has recently become a focus in
planetary science as a potential

Heat from the impact that made Occator probably allowed a mixture of ice, salts, and rock in Ceres's interior to become more fluid and rise up to the surface, scientists reported today at the Lunar and
Planetary Science Conference in The Woodlands, Texas.
Therefore, the strongest motivation for the current scientific review is the need for a synoptic organization of the available knowledge on the field of interactions at different
planetary systems, in parallel with a comparative analysis encompassing the inter-connection among
planetary space weather aspects belonging to different disciplines (e.g. plasma variability and its effects on atmospheric
heating).
While the cold surface conditions and the lack of illumination and

The atmospheric greenhouse effect, an idea that authors trace back to the traditional works of Fourier 1824, Tyndall 1861, and Arrhenius 1896, and which is still supported in global climatology, essentially describes a fictitious mechanism, in which a
planetary atmosphere acts as a
heat pump driven by an environment that is radiatively interacting with but radiatively equilibrated to the atmospheric system.
The
