American Thinker- Print Article: As a climate scientist, I am quite familiar with the background facts that Prof Michael E. Mann (now at Penn State U) so shamelessly distorts in his new book The Hockey Stick and the Climate Wars: Dispatches from the Front Lines.

First, the scientific background:

Mann's claim to fame derives from his contentious (and now thoroughly discredited) "hockeystick" research papers (in Nature 1998 and Geophysical Research Letters 1999). His idiosyncratic analysis of proxy (non-thermometer) data from sources like tree rings, ice cores, ocean sediments, etc. did away with the well-documented Medieval Warm Period (MWP - 900-1200AD) and Little Ice Age (LIA - 1400-1800AD) -- documented by Prof. H.H. Lamb, the founding director of the Climate Research Unit of East Anglia U (CRU-EAU). Mann then asserted that the 20th century was the warmest in 1,000 years. His temperature graph, shaped like a hockeystick (on its side) immediately became the poster child of Al Gore and the IPCC, the U.N. science panel, to support their claim of anthropogenic global warming (AGW).
