An extraordinary series of postings at www.climateaudit.org, the deservedly well trafficked website of the courageous and tenacious Canadian statistician Steve McIntyre, is a remarkable indictment of the corruption and cynicism that is rife among the alarmist climate scientists favored by the UN’s discredited climate panel, the IPCC. In laymen’s language, the present paper respectfully summarizes Steve McIntyre’s account of the systematically dishonest manner in which the “hockey-stick” graph falsely showing that today’s temperatures are warmer than those that prevailed during the medieval climate optimum was fabricated in 1998/9, adopted as the poster-child of climate panic by the IPCC in its 2001 climate assessment, and then retained in its 2007 assessment report despite having been demolished in the scientific literature. It is a long tale, but well worth following. No one who reads it will ever again trust the IPCC or the “scientists” and environmental extremists who author its climate assessments.
