heat at all.

There's also a number of interesting applications in the evolution of Earth's atmosphere that branch off from the runaway greenhouse physics, for example how fast a magma - ocean covered early Earth ends up cooling — you can't lose
heat to space of more than about 310 W / m2 or so for an Earth - sized planet
with an efficient water vapor feedback, so it takes much longer for an atmosphere - cloaked Earth to cool off from impact events than a body just
radiating at sigmaT ^ 4.

(2) In the stratosphere, CO2, being a good IR emitter,
radiates to space the
heat energy it gains from collisions
with other molecules.
With climate and Greenhouse Gas thoeries of Global warming, it appears to me that of most interest is the interface between the Earth's atmosphere and space and the flow of
radiated heat from the sun, what's reflected back from Earth's surface and the consequences of any change in that balance.
This is why (absent sufficient solar or other non-LW
heating) the skin temperature is lower than the effective
radiating temperature of the planet (in analogy to the sun, the SW radiation from the sun is like the LW radiation, and the direct «solar
heating» of the part of the atmosphere above the photosphere may have to due
with electromagnetic effects (as in macroscopic plasmas and fields, not so much radiation emitted as a function of temperature).
One is that the mechanism for the GHG warming is that the
radiated energy from the air is absorbed by the GHGs to
heat the GHG molecule to 900 + degrees, then the energy is released within microseconds and a few centimeters back to the air by collisions
with the air, to return the air & GHGs to equilibrium temperature.
lastly, a point that I made in arguments is that 70 % of the IR
radiated by CO2 hits the ocean and is used up in latent
heat transfer associated
with evaporation.
With adequate training they would be aware of the science that all of the radiant
heat from the earthâ $ ™ s surface that is going to be absorbed by greenhouse gases gets absorbed close to the ground (half within less than 24 meters) and is carried up by convection currents to where it ultimately gets
radiated to space.
Those
with low tops bounce the Sun's energy back into space to keep us cooler, whereas high - level clouds tend to trap

with the physical form change from gas to liquid or solid and this super or sub cooled water returns to Earth for further cooling.
Once a gas is compressed and
heated, it then
radiates the excess

with the surrounding environment.
What it has to do
with the Sun is firstly as the iron gets hotter and hotter you feel greater and greater

An atmosphere that is perfectly transparent to incoming and outgoing radiation can not
radiate and all its
heat content comes from conduction from the surface and is transported through the atmosphere solely by convection
with no loss of energy to space except for the tiny fraction of atoms at the top of the atmosphere that exceed escape velocity.
Heat radiates away from the Earth; there's no need for mass to escape

with the «not

radiate with exactly the same power, uv, blue, green, red, near IR or far IR radiation?
Spencer's article lends support to the discredited idea that cold CO2 [carbon dioxide] high in the atmosphere back -
radiates to Earth's warmer surface,
heating it more and causing it to
radiate to the atmosphere and space
with higher intensity than it would without cold CO2 back - radiation.
Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation /
heat energy absorbing and re
radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which,
with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.
Measuring
with a spectrometer what is left from the radiation of a broadband infrared source (say a black body
heated at 1000 °C) after crossing the equivalent of some tens or hundreds of meters of the air, shows that the main CO2 bands (4.3 µm and 15 µm) have been replaced by the emission spectrum of the CO2 which is
radiated at the temperature of the trace - gas.
This is largely zero - sum in terms of
heat content except for the fact that warmer surfaces will

radiates if it conducts is over its whole surface

The non-radiative effects (convection) and phase changes carry more
heat into the upper atmosphere where there is a greater chance for energy to be
radiated directly to space, less chance of radiative interaction
with molecules on the way out.
But in the example
with two
radiating bodies at different temperatures that was given by Willis, the warmer body does indeed loose
heat to the cooler body, in accordance to the second law of thermodynamics.
To prove the point, they measured the
heat radiated by a silicon nanofibre

In the course of that process
heat energy is released around the planet and
