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 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.
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 gas to liquid or solid and this super or sub cooled water returns to Earth for further cooling.
Heat is being radiated into space from GH gases (including water vapour) in the upper atmosphere.
Satellite measurements show that this lowest layer of the atmosphere is warming as greenhouse gases build up and trap heat that radiates from the Earth's surface.

Such gases absrob heat energy through conduction and convection and then radiate the energy away, some of which is lost to space.
And after that, we can look at whether maybe greenhouse gasses like CO2 could be trapping some of the heat the earth is radiating, thus slowing down the rate the earth cools at.
So, for example, the Sun's effects on the recent «global warming» are said to be of no significance, that it's all due to the greenhouse gas increase absorbing and radiating back / holding in blanket, the infrared heat upwelling from the surface.
Once a gas is compressed and heated, it then radiates the excess heat away, until it achieves equilibrium with the surrounding environment.
So it can pretend that «all downwelling measurements of thermal infrared, longwave, are the result of greenhouse gases trapping the upwelling heat and radiating it back to Earth's surface», as SkepticalScience explains further:
Unless you are going to deny the earth heats the sun at all, then it makes no difference HOW the sun heats the earth, the result is the still the same — the earth then 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 gasses
The earth does not radiate an appreciable amount of heat into space, and the «greehouse gases» do not make the atmosphere less reflective to photons raining down on us from the sun.

In fact, UHI is a cumulative effect of numerous «hot spots» (flux sources) simultaneously radiating IR, and conducting heat to adjacent solids, gases and liquids.
Greenhouse gases trap some of the escaping heat closer to the Earth's surface, making it harder for it to shed that heat, so the Earth warms up in order to radiate the heat more effectively.

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.
