In other words, greenhouse
gases don't retain
heat themselves, but rather redirect outgoing energy
radiated by the surface and lower in the atmosphere, thereby delaying it's ultimate escape to space.
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 ***).

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

radiated to space.
What's more, continually increasing greenhouse
gases increase the imbalance by about 0.3 W / m2 per decade even as the planet warms and
radiates some extra
heat back to space.
But that's actually an understatement by Gallup, since more than 97 % of the world's climatologists say that those carbon
gases, which are given off by humans» burning of carbon - based fuels, are causing this planet's temperatures to rise over the long term, as those carbon
gases accumulate in the atmosphere and also block the
heat from being
radiated back into outer space.
Most of the
heat radiated by the surface is absorbed by trace
gases in the overlying atmosphere and re-emitted in all directions.
Some
heat radiates back to space or trapped in biosphere Balance determines Earth's average temperature
Gases that control in atmosphere are carbon dioxide, methane, water vapor.
As increased levels of greenhouse
gases such as carbon dioxide trap more solar
heat radiating from the Earth's surface, less warmth reaches the stratosphere, which cools as a result.
Basically, as fast as
heat loiters about on our planet's surface, it either
radiates off to space or Water will pick it up and carry it to the upper layers of our atmosphere, where it will change form from
gas to liquid or solid giving off
heat to space while being super cooled at the same time.
This
heat is
radiated to space with the physical form change from

And after that, we can look at whether maybe greenhouse

Unless you are going to deny the earth
heats the sun at all, then it makes no difference HOW the sun

radiates all / some of this
heat, which
heats greenhouse
gasses, which in turn return some of this
heat to the earth.
-- it is not necessary for visible light to
heat the earth, for it to be reradiated as IR — and anyway, by whatever wavelength, the earth * is * warmed by the sun — the earth
radiates IR, which warms its greenhouse

The earth does not
radiate an appreciable amount of
heat into space, and the «greehouse

In fact, UHI is a cumulative effect of numerous «hot spots» (flux sources) simultaneously
radiating IR, and conducting

Greenhouse
gases trap some of the escaping
heat closer to the Earth's surface, making it harder for it to shed that

One idea was that increased IR
radiated from water vapour in these air masses could off - set expansion due to release of latent
heat, and ad drive horizontal circulation This had to be attacked as it showed a role for radiative
gases in atmospheric circulation.
However, it is much easier to figure out what happens when you add more radiative
gases to an atmosphere that already has them: And, the answer is that it increases the IR opacity of the atmosphere, which increases the altitude of the effective
radiating level and hence means the emission is occurring from a lower - temperature layer, leading to a reduction of emission that is eventually remedied by the atmosphere
heating up so that radiative balance at the top - of - the - atmosphere is restored.
