I'm not a climate scientist. I don't even play one on TV. There do seem to be serious problems with the catastrophic anthropogenic global-warming (AGW) thesis, but I remain an agnostic, and I refuse to use political-economic criteria to judge scientific credibility.
Nevertheless, this interesting article about German physicists who insist that AGW is bunk is worth reading.
From the physicists' paper:
(a) there are no common physical laws between the warming phenomenon in glass houses and the fictitious atmospheric greenhouse effects, (b) there are no calculations to determine an average surface temperature of a planet, (c) the frequently mentioned difference of 33 degrees Celsius is a meaningless number calculated wrongly, (d) the formulas of cavity radiation are used inappropriately, (e) the assumption of a radiative balance is unphysical, (f) thermal conductivity and friction must not be set to zero, the atmospheric greenhouse conjecture is falsified.
