THE HOCKEY SCHTICK: Professor inadvertently explains why greenhouse theory is wrong

Professor David Archer of the University of Chicago has posted You-tube videos of his 10 week lecture series for non-science majors on climate change. In lecture 5, The Greenhouse Effect, Archer uses the Stefan-Boltzmann equation to calculate the supposed temperatures of Venus, Earth, and Mars with and without a greenhouse effect. Archer's calculations show the greenhouse effect on Venus is wildly underestimated by 415C (a factor of 36) and wildly overestimated on both Earth (by 23C) and on Mars (by 19C) in comparison to actual observed temperatures. This is despite the fact that CO2 levels are very high and virtually the same on Venus and Mars (around 96%) and only trace (0.039%) on Earth. Archer says in the lecture that one would have to assume the Venus atmosphere behaves like multiple panes of glass in order to obtain an answer near the observed temperature, yet on both Earth and Mars one would have to assume the atmospheres behave like much less than one pane of glass. Leaving aside the fact that no atmosphere behaves like a pane of glass, climate scientists cannot claim that the greenhouse theory comes close to a unified explanation of temperature on any of these 3 planets. The simple fact is the adiabatic lapse rate (effect of pressure with altitude) fully explains the temperature profiles on all 3 planets without any need to invoke a supposed 'greenhouse effect.'
