Climategate Scandal Broadens
Certified consulting meteorologist Joseph D’Aleo of Icecap.us and a computer programmer from San Jose, Michael Smith, have written an expose of extensive manipulation of the temperature data by the federal government’s National Climate Data Center (NCDC) in Asheville, North Carolina and NASA’s Goddard Institute for Space Studies (GISS) at Columbia University in New York City. D’Aleo says in the report, “NOAA is seriously complicit in data manipulation and fraud…CRU’s Director at the time Phil Jones acknowledges that CRU mirrors the NOAA data. ‘Almost all the data we have in the CRU archive is exactly the same as in the Global Historical Climatology Network (GHCN) archive used by the NOAA National Climatic Data Center.’”
1. NCDC is no longer monitoring many actual temperature stations. Coleman explains, “In the transition to a computer averaging system, the National Data Climate Center deleted actual temperatures at thousands of locations throughout the world as it evolved to a system of global grid boxes. The number that goes into each grid box is determined by averaging the temperatures of two or more weather observation stations nearest that grid box.” This method is inaccurate according to D’Aleo because “temperatures are not linear over space, but instead vary enormously because of differences in terrain, elevation, vegetation, water versus land and urbanization." It also makes an apples and oranges situation, comparing today’s averaged grid boxes to past actual station temperatures.
2. The number of weather stations NCDC uses was reduced 75%, from approximately 6,000 to 1,000 stations.
3. The vast majority of the stations cut from the record were from the cooler higher latitudes and altitudes. Smith says, "The more I looked, the more I found patterns of deletion that could not be accidental. Thermometers moved from cold mountains to warm beaches; from Siberian Arctic to more southerly locations and from pristine rural locations to jet airport tarmacs. The last remaining Arctic thermometer in Canada is in a place called 'The Garden Spot of the Arctic,’ always moving away from the cold and toward the heat.”
4. Temperatures then were altered by “homogenization,” a process which always seemed to result in higher readings. According to the report,”the data centers then performed some final adjustments to the gathered data before final analysis. These adjustments are in some cases frequent and undocumented. Examining raw data versus processed final data shows numerous examples where the adjusted data shows a warming trend where the raw data had little change.”
