2) The amount reradiated is increasing. This is observed fact.
Please state reference/paper as to this measurement over time.
4) Laws of electromagnetism and thermodynamics say that when there’s more atmospheric emissivity the temperature will go up.
Not exactly. The correct statement would be; as the atmospheric temperature goes up, atmospheric emissivity goes up (basic physics of black body radiation). The opposite is not true. If a black body is radiating, then it is losing energy, thereby its temperature would be dropping (unless energy is being supplied to it at the same time it is emitting). Now using my corrected statement, if observed black body radiation is increasing w/o any change in the body’s ability to radiate, then one might say that the atmospheric temperature has increased. The best way though is to look at the center frequency of the black body emissions, this is directly correlated to temperature. The center frequency of black body emissions shifts to the right(higher freq) with higher temps. If center frequency does not shift but emissivity ‘flux’ has increased, no temperature change has taken place, but the body has improved its ability to radiate.
ie. chrome on a car under the sun can get very hot even though it is very reflective. This is because its ability to emit as a black body is very poor. On the other hand, dark painted metal will gain a considerable amount of thermal energy but will not get as hot under the same conditions because it is a much better black body emitter. (ignoring for certain types of paint that have odd characteristics)
My personal opinion is that correlating emissivity directly to AGW is too simplistic a far as the earth’s processes. There are both positive and negative feedbacks, with the negative feedback having the ability to shut down/block a large forcing factor(sun). Some of the feedbacks are also affected by the atmospheric emissivity.
