Why Heat Doesn't Flow from Cold to Hot and the Myth of AGW

Pertinent to discussions on the Shattering the Greenhouse Effect thread, this fascinating excerpt from the book Uncertainty: Einstein, Heisenberg, Bohr, and the Struggle for the Soul of Science, explains how physicists came to explain the one-way transfer of heat from hot to cold demanded by the 2nd Law of Thermodynamics using statistical techniques. For the uninitiated, the reason this is of interest in the AGW debate is that climate scientists continue to make the fundamental physical error of assuming that a colder 'greenhouse gas' atmosphere at an average radiating temperature of -5C can heat a warmer Earth surface at +15C in violation of the 2nd Law of Thermodynamics. Without making this erroneous assumption, the entire AGW facade comes crashing down.
