Few realize that our entire solar system is swinging through space passing through areas of greater or lesser energy fields from cosmic particles and background 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.
Allowing for that falling on the oceans, and further decline due to angle of incidence as distance from equator increases, less the amount required by vegetation for photosynthesis, we are left with how much energy for conversion of solar radiation to heat / electricity / catalytic reaction to other fuels?
Note how less radiation comes from the 13 - 17 um band; this is because it comes from higher up, around the tropopause where it is colder — note the coloured temperature curves.
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).
Less TOA cooling will occur if bands are placed where, in the upper atmosphere or near TOA, they absorb more of the increases in radiation from below from surface + tropospheric (+ lower stratospheric) warming.
If not for the temperature discontinuity, then the radiation coming from the surface would be less than what fits the linear T ^ 4 pattern, with the biggest difference at angles near vertical.
I'm no atmospheric scientist and haven't really considered the stratospheric cooling issue but, if an increase in the amount of atmospheric CO2 raised the average altitude from which the stratosphere receives radiation in the CO2 bands, wouldn't it receive less radiation in those bands?
The net result is, earth receives a lot less infrared radiation from the sun than it radiates away.
It is true that this lost solar heating now adds to the LW flux coming from below, but the skin layer only absorbs a tiny fraction of that, so the increase in absorped LW flux from below is less than the decrease in the absorbed SW radiation.
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).

To me, it is more likely the fluctuation in E-UV coming from the sun that causes the warming and cooling effects by changing the reactions that are happening on TOA, i.e. O3, HxOx and NOx are rising now, causing more back radiation of F - UV, meaning less energy going in the oceans.
Once the radiation limits begin to be increased this should have a catalytic effect on reducing emissions: 1) it will mean radiation leaks are understood to be less dangerous that currently thought > less people evacuated from effected zones > reduced cost accident of accidents — reduced accident insurance cost; 2) population takes another look at the effects of radiation > gains an understanding it is much less harmful than they thought > fear subsides > less opposition > easier and less expensive to find sites supported by the people nearby > planning and sight approval costs come down over time
