claim: However, a single scientist, Dr. Ben Santer of Lawrence Livermore National Laboratory, rewrote the draft at the IPCC’s request, deleting all five statements, replacing them with a single statement to the effect that a human influence on global climate was now discernible, and making some 200 consequential amendments.
evidence: Prior to the publication of the Second Assessment Report, the industry group Global Climate Coalition distributed a report entitled The IPCC : Institutionalized Scientific Cleansing to reporters, US Congressmen, and scientists, which said that Santer had altered the text, after acceptance by the Working Group, and without approval of the authors, to strike content characterizing the uncertainty of the science.
