Okay fence sitters. Todays lesson is the physics don't add up. http://climateofsophistry.com/2013/10/2 ... -fraud-20/
I will let Pierre Latour speak here, from a private email discussion:
“The Stefan-Boltzmann equation gives intensity of radiation, W/m2, emitted by a body at temperature T. It is analogous to fluid pressure, kg/m2. Stefan and Boltzmann called it intensity, not heat transfer, because it is intensity, not heat transfer. (It becomes heat transfer in maximum case emitting to 0K surroundings, so it is a max heat transfer. Real transfer is always less.) All bodies radiate with an intensity and they all experience a pressure. But for a fluid to flow there must be a driving force, a pressure difference. Physics teaches the fluid flows from high pressure to lower at a rate proportional to the pressure difference. The pressure at the bottom of the sea is high but uniform so no fluid flow.
For radiant energy to flow, transfer from one body to be absorbed by another body, heating it, there must be a driving force and that force for radiant energy transfer is an intensity difference. Physics teaches that the radiant heat flows from high intensity, to lower intensity, at a rate proportional to the difference (TH4 - TL4). Two identical glowing radiators facing each other radiate intensely but without any heat transfer between them.
The GHGT error is assigning to that second intensity term in the radiant heat transfer law an energy flow from cold to hot. Just because there is an algebraic term in the equation for cooler body radiating intensity does not mean it corresponds to a rate of heat transfer from cold to hot.
Atmospheric CO2 radiates with same intensity in all directions but the direction and rate of heat transfer to surroundings depends on surrounding’s radiating intensity. Energy transfer is asymmetric. So if the K-T 333 back-radiation arrow signifies direction of downward radiation intensity in all directions, ok, if they point it in all directions. But K-T labeled their diagram energy flows, and their back-radiation arrow 333 cannot be a flow, absorbed by surface, warming it further. Hence we have the dispute about semantics of physics which GHE believers dismiss with derision. “
Plus the religious warmers claim only 0.39 percent (a trace gas) of our atmosphere does all of this. Not possible.
