Can Roy Spencer Describe the "Greenhouse Effect"?
There is a new post on the Roy Spencer's description of the "Greenhouse Effect" at The World as Computation.
The comments show again how widely spread is the idea of "backradiation" although it is nowhere described in physics literature, not even on Wikipedia. Notable is also the complete absence of physicists in the debate, leaving room for all sorts of free inventions such as IR-photons busy traveling around the universe carrying little units of heat energy which they deliver to everybody without asking anything, in particular not about the temperature of the recipient.
But radiative heat transfer is a collective phenomenon of resonance between bodies in radiative contact, where the resonance is only causing heating in bodies with low temperature as an expression of the 2nd law as proved in Mathematical Physics of Blackbody Radiation.
