It's an absolute nonsense to say that «cold» radiation can't be absorbed
by warm objects.
Qradiation is the energy radiated
by the warm object S is the Stefan - Boltzmann constant A is the surface area of the warm object Ts is the absolute temperature of the warm object (the Earth) Ta is the absolute temperature of the surrounding medium (ambient temperature of the atmosphere)
Thus in summary, lets see what evidence you have suggesting that cooler photons are actually absorbed
by a warmer object.
I have previously mentioned something similar, ie., not disputing that all objects above absolute zero radiate but that does not automaticlly mean that radiative energy emitted by a colder object is actually absorbed
by the warmer object.
One of these is whether radiation emitted by a colder object is actually absorbed
by a warmer object (and thereby increasing the radiation that the warmer object thereby emits).

The first Hansen Op - Ed quote Tom Scharf
objects to begins «To the contrary...» so presumably Tom Scharf is more at ease with what is being disavowed
by Hansen when he said ``... it is no longer enough to say that global
warming will increase the likelihood of extreme weather... (nor) to repeat the caveat that no individual weather event can be directly linked to climate change.»
We start out
by placing a
warm object — say a heated piece of iron — in the chamber, and then sealing the chamber, Our principle tells us that the heat from the iron will cause the air to cool
by emitting even more heat than it receives.
Re 392 Chris Dudley — I don't understand what you mean
by R ^ 2T ^ 4 — and there should be something about how optical depth is proportional to R, and also, if you're going a significant distance toward the center of such an
object, there is the issue of spherical geometry; if the optical thickness is large enough across small changes in radius, then you don't need to account for the spherical geometry in the calculation of the flux per unit area as a function of the temperature profile and optical thickness; however, the flux per unit area outward will drop as an inverse square, except of course within the layers that are being heated through a different process (SW heating for a planet, radioactivity, latent and sensible heat loss associated with a cooling interior, gravitational potential energy conversion to enthalpy via compression (adiabatic
warming) and settling of denser material under gravity (the later both leads to compression via increased pressure via increased gravity within the interior, and also is a source of kinetic energy which can be converted to heat)...

However, the lead author of the study Crichton cites in the footnote for this assertion stated in a New York Times interview (PDF File) that he

warming or not global
warming».
While you might not realise it, all
warm objects are constantly cooling down
by emitting light, including us.
ie, earth has
warmed, co2 a ghg, man contributes co2,
warming caused in part due to man vs natural processes, for varying opinions of how big that part is) the activist have tried to label them otherwise, not believing earth has

by never defining, the
object of the consensus..
(c) It may also be
objected that the atmospheric circulation depends on the difference of temperature between low and high latitudes and, hence, should be weakened instead of strengthened

While I have enjoyed reading the many threads on adiabatic heating etc... I really can't get
by what appears to me to be a very fundamental problem with this theory of Greenhouse Gas
Warming, namely that a cold
object can heat a
warmer one.
Smokey says: «And is Trenberth implying that if a
warmer object were surrounded
by hundreds of slightly cooler
objects, all radiating toward the slightly
warmer object, that the combined radiation from the slightly cooler
objects would
warm the single slightly
warmer object?
By focusing IR from the small
warm part of the wall, you could
warm the
object up close to 300 K, because the
object would «see» 300K from a much larger area.
The reason I contrasted the two types of «heat pump», heat pumps and air conditioners, was to illustrate the large amount of work (energy) required to circumvent the Second Law — ie to cool an
object further
by moving energy from it to a
warmer one or
warmer surroundings.

For the respondents that would contemplate purchasing a haunted home, the following spooky occurrences would stop them from buying a home: • 75 percent would be scared off
by levitating
objects from purchasing a home; • 63 percent would be deterred
by objects being moved from where they were placed; • 63 percent would be dissuaded
by ghost sightings; • 61 percent would be discouraged
by supernatural sensations; • 61 percent would be scared off
by flickering lights / appliances; • 60 percent would pass on a home with strange noises (footsteps, doors slamming); • 34 percent would be deterred
by warm or cold spots.
