(Investor's Business Daily) The narrative says we're living in dangerous times as man's carbon dioxide emissions heat Earth. But a scientist testifying before Congress showed that the temperature record telling that story can't be trusted.
When the media reported — gleefully because it allowed them to advance their agenda — that 2015 was the hottest year on record, the temperature data that supposedly proved this was collected from surface-based measurements. Is this data trustworthy? Not according to John Christy, distinguished professor of atmospheric science, Alabama's state climatologist and director of the Earth System Science Center at the University of Alabama in Huntsville.
Christy is a co-author of a paper that showed that about two-thirds of 1,218 government weather stations in the continental U.S. were located on sites that distort readings. These stations fix gauges near heat sources, such as air conditioner exhausts, urban structures that give off heat, and other objects "with unnatural thermal mass." Christy told the House Science Committee on Wednesday that "it is difficult to adjust for these contaminating factors to extract a pure dataset for greenhouse detection because often the non-climatic influence comes along very gradually just as is expected of the response to the enhanced greenhouse effect."
