As a pulsar rotates, it emits high - energy radiation, similar to a lighthouse casting beams of light.

Surface radiative energy budget plays an important role in the Arctic, which is covered by snow and ice: when the balance is positive, more solar radiation from the Sun and the Earth's atmosphere arrives on the Earth's surface than is emitted from it.

As a pulsar rotates, it emits high - energy radiation, similar to lighthouse casting beams of light.

The greenhouse gases absorb some infrared radiation emitted by the surface of the Earth and in turn radiate the absorbed energy back to the surface.

Absorption of thermal radiation cools the thermal spectra of the earth as seen from space, radiation emitted by de-excitation is what results in the further warming of the surface, and the surface continues to warm until the rate at which energy is radiated from the earth's climate system (given the increased opacity of the atmosphere to longwave radiation) is equal to the rate at which energy enters it.

Vibrational modes in molecules with three or more atoms (H2O, CO2, O3, N2O, CH4, CFCs, HFCs...) include bending motions that are easier to excite and so will absorb and emit lower energy photons which co-incide with the infrared radiation that the Earth emits.

The sun, which is quite hot (about 5800K), emits most of its energy at between 0.2 microns and 4 microns (solar or short wave radiation, or plain sunlight), while the Earth's surface emits the most energy at wavelengths between 5 and 50 microns (the so - called thermal Infrared region of the spectrum).

The imbalance is not between IR absorbed and IR emitted by a layer of atmosphere, but between the incoming shortwave solar energy from space and the outgoing longwave energy emitted to space, due to the increasing difference between the ground temperature and the temperature of the level from which re-emitted radiation can escape to space.

Now, all things emit radiation depending on their temperature [note2], the higher the temperature the more the amount of emitted energy.

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.

The frequency at which photons are emitted or absorbed is small relative to the rate of energy redistribution among molecules and their modes, so the fraction of some molecules that are excited in some way is only slightly more or less than the characteristic fraction for that temperature (depending on whether photons absorption to generate that particular state is greater than photon emission from that state or vice versa, which depends on the brightness temperature of the incident radiation relative to the local temperature).

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.

What will the energy of the radiation emitted by a CO2 molecules in the atmosphere at NTP, and does it depend on the temperature of the air?

What I meant was that Planck radiation increases with body or amb ient temperature, but higher temperature, per the Boltzmann distribution, makes it more probable that rotation, vibration, and / or electronic levels will be excited, and therefore less likely to emit relaxation energy, though as you point out this may not be exactly what happens physically — emission radiation is more flat than anything with increasing temperatures.

Pekka Pirilä: Where the effect of increase in CO2 is important for the energy balance is in the upper troposphere, because a significant part of the radiation emitted upwards by CO2 of the upper troposphere goes trough the tropopause to stratosphere or through it to open space.
