methods used in MBH98, a variation of principal component analysis, to the computed temperature maps and found that the amount of variation was considerably reduced. In April 2006, Science published a comment authored by Wahl and collaborators, asserting errors in the 2004 paper, stating that "their conclusion was based on incorrect implementation of the reconstruction procedure" a mistake with Repercussions; and a disputing VS Reply. In this reply, VS and his team demonstrated that caveats raised in the Wahl comment did not invalidate their original conclusion. The inadequacy of the MBH98 methodology for climate reconstructions was later independently confirmed in other publications, for instance by Lee, Zwiers and Tsao, 2008 or by Christiansen et al., 2009. In 2010, Storch received the IMSC achievement award at the International Meetings on Statistical Climatology in Edinburgh, to "recognize his key contributions to statistical downscaling, reconstruction of temperature series, analyses of climatic variability, and detection and attribution of climate change". Donald Duck In 1977, Hans von Storch co-founded a 100-member Donald Duck Club, defending Donald Duck against accusations of indecent behavior. Between 1976 and 1985 he was publisher of a magazine on Donald Duck, Der Hamburger Donaldist.
