That's because once the sunlight hits an object, it heats up and emits infrared radiation — a form of radiant heat that gets trapped in your home.

Isn't one important feature of cooling the stratosphere by emitting heat absorbed by ozone from incoming shortwave radiation, that this cooling has little effect on lower parts of the atmosphere since there is not much mixing between these air masses?

If it is correct, then the IR radiation emitted from the earth's surface and absorbed will be nearly completely thermalized and not re-emitted, i.e. it will heat the air.

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.

Therefore, for practical purposes, the sole source of excess heat if we increase CO2 is IR emitted by the surface from absorbed solar radiation,.

With some LW absorbing optical thickness, the atmosphere can emit radiation to space, so some heat will flow into the atmosphere from where solar heating occurs to get to space.

A huge laser delivers a large amount of energy in a short time to heat the walls of the larger chamber, and the radiation emitted from those walls in turn drives the small capsule to a very small size, increasing the density of the gases inside to much higher density than lead and heating it at the same time to very high temperatures required for fusion to occur.

Actually, though, most of the OLR originates from below the tropopause (can get up around 18 km in the tropics, generally lower)-- with a majority of solar radiation absorbed at the surface, a crude approximation can be made that the area emitting to space is less than 2 * (20/6371) * 100 % ~ = 0.628 % more than the area heated by the sun, so the OLR per unit area should be well within about 0.6 % of the value calculated without the Earth's curvature (I'm guessing it would actually be closer to if not less than 0.3 % different).

In the absence of solar heating, there is an equilibrium «skin temperature» that would be approached in the uppermost atmosphere (above the effective emitting altitude) which is only dependent on the outgoing longwave (LW) radiation to space in the case where optical properties in the LW part of the spectrum are invariant over wavelength (this skin temperature will be colder than the temperature at the effective emitting altitude).

The increasing greenhouse effect leads to a radiation imbalance: we absorb more heat from the sun than we emit back into space.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

In equilibrium these would be balanced by upward transfer of infrared radiation emitted by the surface, by sensible heat flux (warm air carried upward) and by latent heat flux (i.e. evaporation — moisture carried upward).

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).
