The regular weekly dose of climate deniers' peer-reviewed literature - something that according to Naomi Oreskes can't exist, yet it seems to appear almost every week. ;-)
A new, June 2007 issue of the Journal of Non-Equilibrium Thermodynamics has a paper called
Does a global temperature exist?by Christopher Essex, Ross McKitrick, and Bjarne Andresen. They argue that the concept of a global temperature is ill-defined because it heavily depends on the choice of statistical methods. The choice of the methods is thus a political decision, not a part of the scientific method.
The paper is inconvenient for RealClimate.
