Chairman, Scientific Council of Central Laboratory for Radiological Protection
Warsaw, Poland written for the US Senate Committee on Commerce, Science, and Transportation in March 2004:
"(...) Improper manipulation of data, and arbitrary rejection of readings that do not fit the pre-conceived idea on man-made global warming is common in many glaciological studies of greenhouse gases. In peer reviewed publications I exposed this misuse of science. Unfortunately, such misuse is not limited to individual publications, but also appears in documents of national and international organizations. For example IPCC not only based its reports on a falsified "Siple curve", but also in its 2001 report used as a flagship the "hockey curve" of temperature, showing that there was no Medieval Warming, and no Little Ice Age, and that the 20th century was unusually warm. The curve was credulously accepted after Mann et al. paper published in NATURE magazine. In a crushing criticism, two independent groups of scientists from disciplines other than climatology (i.e. not supported from the annual pool of many billion "climatic" dollars), convincingly blamed the Mann et al. paper for the improper manipulation and arbitrary rejections of data. The question arises, how such methodically poor paper, contradicting hundreds of excellent studies that demonstrated existence of global range Medieval Warming and Little Ice Age, could pass peer review for NATURE? And how could it pass the reviewing process at the IPCC? The apparent scientific weaknesses of IPCC and its lack of impartiality, was diagnosed and criticized in the early 1990s in NATURE editorials. The disease, seems to be persistent. (...)"
