There is a small effect from the radiative properties of the «GHG's», but they simply act as a sort of hybrid thermal / optical delay line which delays
the flow of any single photon through the Sun / Earth / Atmosphere / Universe system by causing it to make multiple «bounces» through the system: surface / GHG / surface / GHG / escape to the energy free void of space.

When the device was switched on, electrons
flowed single - file through each double quantum dot, causing them to emit
photons in the microwave region
of the spectrum.
This is a pretty serious picking
of nits — thermo textbooks regularly state that there is «no heat
flow» between reservoirs in thermal equilibrium because there is no net macroscopic
flow of heat between the two reservoirs, for the simple reason that thermodynamics averages over molecular (or in the case
of radiation,
single photon) scale local fluctuations.
SPECT scan, which stands for
Single Photon Emission Computed Tomography, is used to show the function
of organs, i.e. blood
flow and brain activity.
