I ask because my limited understanding is that temperature is related to kinetic energy, but would not register an overall increase in potential energy, in which case energy from the sun could be partitioned in heat energy emitted from the planet and work used to increase potential energy, possibly allowing an energy balance that does not require a radiation balance, and also does not require a warming effect.

1) Greenhouse gasses absorb infrared radiation in the atmosphere and re-emit much of it back toward the surface, thus warming the planet (less heat escapes; Fourier, 1824).

It also may impact the planet's radiation balance - largely by changing cloudiness - I have no idea whether this effect would warm or cool, that would require detailed modeling.

In the case of an increase in greenhouse gases (which cause a warming), that implies that the planet will be absorbing more solar radiation than it emits as longwave radiation.

It is also inferred that the planet is now out of radiation balance by 0.5 to 1 W / m2 and that additional global warming of about 0.5 °C is already «in the pipeline».

For example simple spectroscopy dictates that the CO2 molecule vibrates, stretches, and rotates creating quantized absorption lines that are Doppler broadened and pressure broadened and absorb the infrared radiation coming from the warmed planet.

Thus we hear so much about «down welling» re - radiation from the atmosphere warming up the planet dangerously because humanity is releasing a certain amount of CO2 that would not otherwise be in the atmosphere.

It has been understood since the 19th century that some gases absorb infrared radiation (IR) that is emitted by the planet, slowing the rate at which the planet can cool and warming the surface.

The ability for CO2 to warm the surface of a planet through the absorption of infrared radiation is well known.

All of it will be dumped into the atmosphere, where it will trap infra - red radiation and warm the planet.

The problem is that LW radiation becomes a circular game when the reason the planet is warming is that greenhouse gasses are reducing LW radiation to space, while at the same time LW radiation to space increasing.

During nighttime, clouds prevent the surface IR radiation from escaping, warming the planet.

When heat energy gets released from Earth's surface, some of that radiation is trapped by greenhouse gases like CO2; the effect is what makes our planet comfy temperature-wise, but too much and you get global warming.

They are also wrong in assuming that the Sun was capable of warming the surface of Venus, Earth or other planets to the observed temperature which is then maintained by back radiation being supposedly the only process that slows such surface cooling.

At this point, very simple physics takes over, and you are pretty much doomed, by what scientists refer to as the «radiative» properties of carbon dioxide molecules (which trap infrared heat radiation that would otherwise escape to space), to have a warming planet.

In turn, the warmed atmosphere emits longwave radiation, some of which radiates toward the Earth's surface, keeping our planet warm and generally comfortable.

Most of the emitted longwave radiation warms the lower atmosphere, which in turn warms our planet's surface.»

Increased concentrations of greenhouse gases, such as CO2, reduce the amount of outgoing longwave radiation (OLR) to space; thus, energy accumulates in the climate system, and the planet warms.

«The ability of a planetary atmosphere to inhibit heat loss from the planet's surface, thereby enhancing the surface warming that is produced by the absorption of solar radiation.

Global warming refers to an increase in the average temperature of the Earth as a result of the greenhouse effect, in which gases in the upper atmosphere trap solar radiation close to the planet's surface instead of allowing it to dissipate into space.

Slowing the escape of radiation to space means the planet is warmer than it would have been otherwise.

As the Chief tells us, clouds have changed from the late 20thC to the early 21stC, resulting in a greater reflection of incoming SW radiation (the prime source of our planet's warming).

As far as I can understand it simply says that anything that blocks the outgoing radiation will make the planet warmer.

The downwelling radiation from the shell, however, warms the planet.

although the cooler planet emits radiation toward the warmer planet, supposing that one were nominally 100K and the other 150K, at some point, supposing they were fixed to receive one another's thermal influuence they would thermalise, if there were not the presence of another radiating body, although radiation goes in all directions, not just towards other hypothetical planets, and may lead to Kelvin's heat death hypothesis where there was no thermal energy left.

It has to warm the warmer planet... but not as much as the warmer planet is cooled by its own radiation.

On a planet with no atmosphere surrounded by a steel shell, where the planet is generating 235 W / m ^ 2, then the radiation will warm the shell.

«The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.»

If you agree that both planets radiate, what do you think is happening to the radiation from the cooler planet that hits the warmer planet?

The shell will still have to emit the total radiation of the planet to space, but the planet will not be warmed as much by the radiation of the shell.

This radiation keeps the planet warmer than it would be without the shell.

The greenhouse effect is the process by which radiation from the planet's atmosphere [back radiation] warms the planet's [lower atmosphere] above what it would be if it had an atmosphere without any GHG's — a very different situation.

That is, carbon dioxide pumped into the atmosphere through profligate fossil fuel use since the Industrial Revolution, was trapping infrared radiation and warming the planet.

«Volcanic eruptions tend to counteract global warming but as the planet heats up and our atmosphere changes, we've found that fewer eruptions will be able to reflect the sun's radiation,» said Thomas Aubry, a PhD student studying climate and volcanoes.

In particular, in layers of air at different altitudes they found a different balance between the way clouds trapped radiation and warmed the planet, or reflected sunlight back into space and cooled it.

By showing that (a) there are no c ommon physical laws between the warming phenomenon in glass houses and the fictitious atmospheric greenhouse effect b) there are no calculations to determine an average surface temperature of a planet, (c) the frequently mentioned difference of 33 C a meaningless number calculated wrongly, (d) the formulas of cavity radiation are used inappropriately, (e) the assumption of a radiative balance is unphysical, (f) thermal conductivity and friction must not be set to zero, the atmospheric greenhouse conjecture is falsified.

They come up with all kinds of hypothetical feedback mechanisms involving more natural aerosol emissions in response to global warming: Dimethylsulfide from marine phytoplankton (although a very intriguing possibility, this has never been confirmed to be a significant feedback mechanism, and there is ample evidence to the contrary, which is omitted from the report), biological aerosols (idem), carbonyl sulfide (idem), nitrous oxide (idem), and iodocompounds (idem), about which they write the following: «Iodocompounds — created by marine algae — function as cloud condensation nuclei, which help create new clouds that reflect more incoming solar radiation back to space and thereby cool the planet.»

So, now we know that the more active sun warms the planet directly with increased incident radiation and indirectly both by reducing low cloud and likely by elevating the proportion of gaseous water — the most important greenhouse gas.

These changes in cloud cover could affect how much of the sun's radiation is reflected by the clouds, leading to a slightly warmer planet, the scientists said.
