Oh, the irony

 Readers may remember the controversy over the mistake made in a recent paper by Ross McKitrick and Patrick Michaels, which hinged on an error in calculation of the cosine of latitudes.  In this context, they may be interested to see this comment from the paper by Von Storch et al. (see last issue) that shattered any remaining credibility held by Michael Manns hockey stick:

Monthly nearsurface temperature anomalies were standardized and subjected to an Empirical Orthogonal Function Analysis, in which each grid point was weighted by (cos f)^1/2, where f is the latitude (Mann et al. 1998 erroneously use a cos f weighting).
