When the team looked at the overall balance between the radiation upward from the surface of the ice sheet and the radiation both upward and downward from the upper levels of the atmosphere across all infrared wavelengths over the course of a year, they found that in central Antarctica the surface and lower atmosphere, against expectation, actually lose more energy to space if the air contains greenhouse gases, the researchers report online and in a forthcoming Geophysical Research Letters.

Clouds alter the amount of sunlight, or radiation, that can reach Earth, affecting Earth's energy balance, and in some areas can lead to precipitation.

So in order to constrain the climate sensitivity from the paleo - data, we need to find a period under which our restricted subsystem is stable — i.e. all the boundary conditions are relatively constant, and the climate itself is stable over a long enough period that we can assume that the radiation is pretty much balanced.

An energy surplus there gives rise to warming which causes a rise in infra - red radiation leading to more energy loss at the top of the atmosphere and hence a trend back into energy balance (negative feedback).

However, the other terms in the energy balance directly or indirectly affect the amount of absorbed solar radiation which is available for ablation.

ENSO changes the cloud cover and water vapour amounts and so you would expect it to affect the Top - of - the - atmosphere radiation balance which changes the overall amount of heat in the system.

And we know that this rise in CO2 - concentration changes the radiation balance of the planet and leads to a warming of global surface temperature.

Detailed studies of the energy balance and ablation of the Zongo and Chacaltaya glaciers support the importance of air temperature increase, and identify the increase in downward infrared radiation as the main way that the effect of the warmer air is communicated to the glacier surface [Wagnon et al. 1999; Francou et al, 2003].

They don't have to be scientists to understand that the higher energy waves of visible light from the Sun can penetrate through CO2, H2O, CH4, NOZ etal in the atmosphere, but the lower energy radiation of infra - red waves, from Earth's surface, have problems getting back out through these molecules, and a new energy balance has to be established in the form of rising temperature.

What happens at the «top of atmosphere» — the level where outgoing radiation leaves for space, not itself a very easy concept — is the restoration of equilibrium, the increase in temperature that, through Helmholtz - Boltzmann at the Earth's brightness temperature 255K, restores the balance between incoming and outgoing energies.

In either case the temperature is independent of the details of the temperature structure below, the key point is that the total outgoing radiation must balance the incoming solar radiation.

Earth's energy balance In response to a positive radiative forcing F (see Appendix A), such as characterizes the present - day anthropogenic perturbation (Forsteret al., 2007), the planet must increase its net energy loss to space in order to re-establish energy balance (with net energy loss being the difference between the outgoing long - wave (LW) radiation and net incoming shortwave (SW) radiation at the top - of - atmosphere (TOA)-RRBIn response to a positive radiative forcing F (see Appendix A), such as characterizes the present - day anthropogenic perturbation (Forsteret al., 2007), the planet must increase its net energy loss to space in order to re-establish energy balance (with net energy loss being the difference between the outgoing long - wave (LW) radiation and net incoming shortwave (SW) radiation at the top - of - atmosphere (TOA)-RRBin order to re-establish energy balance (with net energy loss being the difference between the outgoing long - wave (LW) radiation and net incoming shortwave (SW) radiation at the top - of - atmosphere (TOA)-RRB-.

This will only be balanced (in a quasi-equilibrium way) when the surface temperature rises sufficiently to increase the outgoing long wave radiation.

This is because part of the outgoing radiation signal (albeit small) is emerging from relatively warm layers aloft, and thus slightly less emission is demanded from the troposphere in order to satisfy planetary energy balance.

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.

Thus the radiation heat balance, according to the IPCC, in the NH must be far less positive than in the SH (as example: a loss of 5 W / m2 TOA due to aerosols in the NH Indian Ocean).

The general argument however is being discussed by rasmus in the context of planetary energy balance: the impact of additional CO2 is to reduce the outgoing longwave radiation term and force the system to accumulate excess energy; the imbalance is currently on the order of 1.45 * (10 ^ 22) Joules / year over the globe, and the temperature must rise allowing the outgoing radiation term to increase until it once again matches the absorbed incoming stellar flux.

There may be self sustaining internal oscillations which feed the changes in SST / air circulation / cloud cover / radiation balance, back and forth (AMO?).

Under steady - state conditions, the total radiation absorbed by the Earth must match the total radiation emitted by the Earth; that's what radiative balance or imbalance means in the climate literature.

Actually there can be convection from the surface that is balanced by some of the radiation from within the troposphere, but in the approximation of zero non-radiative transfer above the tropopause, all the flux into the stratosphere must be from below (absent solar heating).

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».
