I can follow the maths if I screw up my face and concentrate but, as I have more of an engineering background, I like to be able to visualise the concepts.
Your explanation above is compelling.
I like to ski.
I imagine standing in a snowy ravine on a cloudless day with the sun shining on one side of the ravine only.
I am equidistant from both sides of the ravine.
I am in the shade and there is no wind.
The question is, would I feel warmer on the side of me that is facing the side of the ravine that has the sun on it?
Would there be reflected heat?
I suspect not.
At least not until the sunburn set in!
What you "feel" is not relavent to what is happening. The only factor at work with regards to manmade global warming is EM fields. The EM field emitted from the earth is greater in magnitude than the EM field emitted by the atmosphere. Therefore, no energy is transferred from the atmosphere to the surface of the earth. Without downdwelling radiation, there can be no manmade global warming and the math simply does not support the claims of downdwelling radiation because no amount of wishing can make energy from a weaker EM field overcome and move "upstream" of the direction of propagaion of a more powerful EM field.
