NASA’s source In “Cooling climate ‘consensus’ of 1970s never was” (SN: 10/25/08, p. 5), Science News includes a graph, attributed to NASA, that shows temperature deviations from the year 1880. The data clearly indicate a distinct warming trend throughout the period. Why is it that over the past two years I have very painstakingly researched the data from more than 200 weather stations from every continent, including more than 20 north of the Arctic Circle, and I haven’t found a single one that indicates a trend that even remotely resembles that represented by the graph in your article? The difference between my primary research and the data from NASA is disconcerting.
