You learn something new every day. In this case, it's not so new, but it needs to be repeated.

We thus find ourselves in the situation that the entire theory of man-made global warming—with its repercussions in science, and its important consequences for politics and the global economy—is based on ice core studies that provided a false picture of the atmospheric CO2 levels. Meanwhile, more than 90,000 direct measurements of CO2 in the atmosphere, carried out in America, Asia, and Europe between 1812 and 1961, with excellent chemical methods (accuracy better than 3%), were arbitrarily rejected. These measurements had been published in 175 technical papers. For the past three decades, these well-known direct CO2 measurements, recently compiled and analyzed by Ernst-Georg Beck (Beck 2006a, Beck 2006b, Beck 2007), were completely ignored by climatologists—and not because they were wrong. Indeed, these measurements were made by several Nobel Prize winners, using the techniques that are standard textbook procedures in chemistry, biochemistry, botany, hygiene, medicine,nutrition, and ecology. The only reason for rejection was that these measurements did not fit the hypothesis of anthropogenic climatic warming. I regard this as perhaps the greatest scientific scandal of our time. From among this treasure of excellent data (ranging up to 550 ppmv of measured CO2 levels), the founders of the anthropogenic global warming hypothesis (Callendar 1949, Callendar 1958, and Keeling 1986) selected only a tiny fraction of the data and doctored it, to select out the low concentraions and reject the high values—all in order to set a falsely low pre-industrial average CO2 concentration of 280 ppmv as in globally averaged temperatures since the mid-20th century. This manipulation has been discussed several times since the 1950s (Fonsel et al. 1956, Jaworowski et al. 1992b, and Slocum 1955), and more recently and in-depth by Beck 2007.

Print that out and pass it around at the next eco-freak convention.
