However it appears to me that lower layers of the atmosphere must also be losing energy via long wavelength radiation since they are gaining energy via convection from below.

CO2 reduces the rate at which the atmosphere loses its energy to space via infrared radiation, which in turn reduces the flow of energy from the Earth's surface to the atmosphere.

There is of course a direct heat exchange between the ground and the atmosphere, but the main transfer happens via heat radiation.

At face value it requires that no energy can be transfered via collisions, i.e. no thermal conductivity, no viscosity, no diffusion... Even for CO2, there is no mechanism for the transfer of energy from rotational / vibrational degrees of freedom to translational motion which has no coupling with a radiation field.

http://www.vukcevic.talktalk.net/NFC1.htm http://www.vukcevic.talktalk.net/LFC20.htm Re UV: This is a copy of a note I wrote some 5 - 6 years ago with minor changes (I occasionally quote it here and there since I think it still has some merit) Both UV and the particle radiation (particle radiation is a function of solar activity and the strength of Van Allen belt, via the Earth's field strength) could have far larger indirect contribution by controlling plankton volumes, and in turn changing the oceans» clarity and CO2 absorption.

He theorizes that the Earth's temperature has warmed in the modern era as a consequence of the strong solar activity during the 20th century (the Modern Maximum) shielding cosmic ray intensification and thus reducing decadal - scale cloud cover, which leads to warming via an increase in absorbed surface solar radiation (as illustrated here by Ogurtsov et al., 2012 and detailed by Avakyan, 2013, McLean, 2014, and others).

Is this, 64w / m ^ 2, perhaps a measure of that portion of the blackbody radiation energy emitted from the earth («earthshine») that is blocked by the saturated H2O absorption spectrum as opposed to the relative ability of any given parcel of air to capture or export heat via the H2O photon radiation path?

If what they believe is true — IR radiation is blocked by glass — then what is physically happening in these experiments is that the heat lamp is simply heating the container itself which in turn heats via conduction the gases inside of the container and again, the CO2 gas warms faster and to a higher temperature than the air because its specific heat is lower.

Although radiation to space occurs over the whole planet there is a general movement of heat from equator to poles via the oceans and atmosphere.

Doesn't this make heat release by IR radiation part of the process at a molecular level, or is heat release by dissipation via gas to droplet collisions much more dominant?
