Just guessing here, but I think the above response in the comments for the RC article by Minnett discusses where Rob Painting thinks Aaron Lewis is misunderstanding the skin layer and how the enhanced GHE
slows heat loss from the oceans, which, obviously, results in increased OHC.
If on the other hand you mean that the GHGs act like insulation which
slows the heat loss from the surface, I would have to think about that, but can't at this point disagree that it is possible.
When the Arctic freezes over the ice insulates the sea and
slows the heat loss from the N pole, when the Arctic ocean has less ice then more heat radiates off to space.
Just as there is no «33 °C warming by greenhouse gases from the minus 18 °C it would be without them» — when the real blanket which
slows heat loss is reinstated — the heavy voluminous fluid ocean atmosphere of real gas, mainly nitrogen and oxygen, and when the Water Cycle is reinstated.
Nice misconception you have going there but the real argument is that CO2 can lower the temperature gradient of the cool skin layer, which
slows the heat loss to the atmosphere and increased levels of greenhouse gases lead to more heat being stored in the oceans over the long - term.
If the bucket were dragged at sampling depth for a few minutes before extraction, the walls of the bucket would have come near the ambient water temperature,
slowing heat loss from the captured water.
No it doesn't, because immediately the cold blanket will take heat from you, it can
slow your heat loss and act to delay conduction of your body's heat to the cold air around you, which is why you feel cold in the first place, and depending on how cold the air and how effective the blanket, you will hopefully regain your body's working temperature, and if very efficient, could make you overheat.
Half of the heat that is lost from the inner chamber to the shell is radiated back inward, keeping the contents warm and
slowing heat loss.
It seems to me that so far, having determined that radiative energy can
slow the heat loss from the surface, the questions which remain unresolved are:
I doubt that many people would challenge the assertion that the warmer the atmosphere,
the slower the heat loss from the surface of the Earth.
That the radiated energy of cold ice contributes to
slowing heat loss from a person is not disputed.

The softer reading, especially
slower export orders, adds to concerns about an expected
loss of momentum in the world's second - largest economy, as policymakers navigate debt risks and a
heated trade row with the U.S.
Vitamin C, vitamin B6, and carotenoids are good examples of nutrients highly susceptible to
heat, and for this reason, their
loss from food is very likely to be
slowed down through refrigeration.
After 24 hours of sleep deprivation, normal flies reacted
slower to
heat in their cages, but the mutants reacted as if they were fully rested, indicating that they didn't need to make up for their slumber
loss.

Cold water will cause constriction of the arteries and veins near the surface of the body, which will inhibit
heat loss and
slow the cooling process.
Their fur acts as a thermal regulator to
slow down the process of
heat absorption and
heat loss.
That the
heat absorption of the ocean as a whole (at least to 2000 m) has not significantly
slowed makes it clear that the reduced warming of the upper layer is not (at least not much) due to decreasing
heating from above, but rather mostly due to greater
heat loss to lower down: through the 700 m level, from the upper to the lower layer.
Insulation basically
slows the rate of
heat loss, so the more insulation you have, the more the
heat loss is
slowed.
2)
Heating up the 1 mm (or smaller) topmost layers of the ocean (the «skin») decreases the thermal gradient thus
slowing the
loss of
heat from the ocean into the atmosphere.
If the sun suddenly shut off, the earth would cool down quickly, and get so cold that the greenhouse gases (most, if not all; certainly water vapor and CO2 - methane freezes at 91 degrees k or -182 deg C) that
slow the
loss of
heat to space would condense out, making the equilibrium surface temperature even colder.
You mention the silvering of a coffee flask preventing
heat loss by radiation, but the key preventer of
heat loss is the vacuum which
slows cooling by conduction and convection.
What the insulation does is to
slow (via reduced velocity) the inexorable
loss of
heat from inside to outside.
Once it is hot, the
heat loss will be
slower with the insulation than without it, but it will not go up because it is insulated.
Changes in earth's
heat from the interior plus a
slow loss of atmosphere could explain this over all
slow cooling.
It seems to be that the cooler a planet is, the faster the
heat loss of it's internal
heat, and hotter it is, the
slower this
loss.
Therefore it seems the
loss of the
heat generated from planetary formation is much
slower with large planets - large planets with big atmospheres.
Greenhouse gases
slow down the rate of
heat -
loss from the surface of the Earth, like a blanket that
slows down the rate at which your body loses
heat.
These temperatures in the base of the troposphere
slow down and even stop the surface cooling in the early pre-dawn hours, regardless of radiation
losses which are balanced by «
heat creep» diffusion and conduction back into the surface.
The latest catchphrase is that GHGs «
slow down» the radiative
heat loss by «scattering» a portion — some say half — and therefore the Earth's surfaces do not cool down as much as they would during the night as they would with less GHGs.
The flow rate of that specific IR band has been
slowed somewhat, but there has been minimal
loss of the «bulk» of photons, not much
heat transfer into the atmosphere.
Warming in the oceans hasn't
slowed, and other impacts have accelerated — including Arctic ice melt, mass
loss in ice sheets and glaciers, and a dramatic increase in
heat waves around the world.
To summarise the arguments presented so far concerning ice -
loss in the arctic basin, at least four mechanisms must be recognised: (i) a momentum - induced
slowing of winter ice formation, (ii) upward
heat - flux from anomalously warm Atlantic water through the surface low ‐ salinity layer below the ice, (iii) wind patterns that cause the export of anomalous amounts of drift ice through the Fram Straits and disperse pack - ice in the western basin and (iv) the anomalous flux of warm Bering Sea water into the eastern Arctic of the mid 1990s.
This essentially is a moderating effect, and does not seem to be dependent on re-radiation of IR trapping greenhouse gases in anyway, except to the extent that it
slows the rate of
heat loss at night (which may very well be a real — albiet a small — effect).
«Much of our confidence stems from the fact that our model does well at predicting
slow changes in ocean
heat transport and sea surface temperature in the sub-polar North Atlantic, and these appear to impact the rate of sea ice
loss.
Your house insulation works by simply
slowing the rate of
heat loss of you house... but clearly there is no re-radiation occurring from your insulation back to the house.
So with respect to the surface and the atmosphere, the atmosphere doesn't
heat the surface, or really make it warmer, all it does is
slow radiative
heat loss, instead of losing 356W / m ^ 2, with a 333W / m ^ 2 atmosphere all it really loses is 23W / m ^ 2.
«what does happen is that the water surface radiates away at about 400W / m ^ 2, in fact the top few microns will be cooler than the water a mm deeper because the transfer of
heat from lower down (conduction, convection, diffusion etc.) is
slower than the
loss from the surface.»
In making that latter statement, I am not excluding that the general temperature of the atmoshere (whatever that may be) does not
slow down the
heat loss from the surface or affect the height at which energy is radiated into space.
Generally Accepted Explanations for discrepancy: Greenhouse effect ADDS
heat and radiation to surface by some magical mechanism explained vaguely as: backradiation; insulation;
slowing of
loss of
heat by backradiation; or other other claptrapcrap ™.
I have no problem with the argument on net energy flow and that if the atmosphere is warmer it
slows down the
heat loss from the warmer earth (or ocean).
The surface won't warm up to where it was before, but also the
heat loss slows as a result of only the net difference between the energy radiated from the surface and the energy «returned» from the atmosphere being lost from the surface.
Summary: Surface can not be continually irradiating 390 wm - 2, if Earth is receiving only 342 wm - 2, EVEN IF THE
HEAT LOSS IS
SLOWED BY BACKRADIATION.
If increased it will
slow down the
heat loss from the black body.
«Surface can not be continually irradiating 390 wm - 2, if Earth is receiving only 342 wm - 2, EVEN IF THE
HEAT LOSS IS

Obviously that doesn't happen, what does happen is that the water surface radiates away at about 400W / m ^ 2, in fact the top few microns will be cooler than the water a mm deeper because the transfer of
heat from lower down (conduction, convection, diffusion etc.) is
slower than the
loss from the surface.
Following cessation of emissions, removal of atmospheric carbon dioxide decreases radiative forcing, but is largely compensated by
slower loss of
heat to the ocean, so that atmospheric temperatures do not drop significantly for at least 1,000 years.
I went to type «warm clothing» and thought «Wait, I can't write the clothing is warm since what it does is
slow the rate of
heat loss, it doesn't provide warmth...»)
There is no power source so all the blanket is doing is
slowing the rate of
heat loss.
