1) total absorbed solar radiation on the order of 1e27J / yr from total incident radiation times (1 - bond albedo)

sigmaT ^ 4 is the upward blackbody radiation (based on stefan - boltzmann) at the surface, «a» is the albedo (reflectivity), so (1 - a) is the fraction of incident solar radiation that is absorbed by the planet.

So your additional information on «total absorbed solar radiation» is interesting, but not necessary to the discussion?

Greenhouse gases (like CO2, CH4 or water) absorb and re-radiate infra - red (IR) radiation that is emitted from the planet's surface at rates that depend on the temperature (the Stefan - Boltzmann law).

All experiments on co2 show how it absorbs infrared radiation, not how it raise the temperature of the heat source.

That will have an effect on the geometric absorption of heat I suppose, relational to the amount of GHG's at a given time and the amount of earth absorbing the solar radiation.

This is very difficult to explain to a non-scientist, but basically it is an established scientific fact based on long - established experiment and theory that simple molecules like O2 and N2 don't absorb infra - red radiation whereas more complicate molecules such as CO2 and H2O can.

Causality of CO2 influence on climate is, after all, proved by experiments of its effect on absorbing longwave radiation.

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).

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.

I explained to you on your own website that, whether you call them greenhouse gases or not, CO2, CH4, N20 behave differently from N2 and O2: GHGs absorb outgoing long wave radiation and N2 and O2 don't.

Surface melt on the ice sheet is constrained by the albedo, but a lake is dark and could absorb much more solar radiation.

Increased human activity disproportionately in the northern hemisphere may lead to greater particulate (mostly soot like with relatively high absorptivity) deposition on Arctic ice which absorbs solar radiation and leads to the ice melting.

Spencer + Braswell have shown that over the tropics on a shorter - term basis, the net overall feedback from clouds with warming is negative; this is largely due to an increase in reflection of incoming radiation by increased clouds with a smaller effect from the reduction of energy trapping high altitude clouds, which slow down outgoing radiation by absorbing and re-radiating energy.

This acts as a positive feedback on the surface warming, because water vapor itself is a powerful greenhouse gas that, like CO2, absorbs and re-emits longwave radiation back to the surface.

Here is the IPCC on stratospheric cooling: «When the CO2 concentration is increased, the increase in absorbed radiation is quite small and increased emission leads to a cooling at all heights in the stratosphere.»
