PRIMARY UNITED STATES CLIMATE CENTERS NOW CAUGHT IN DATA MANIPULATION
It has been revealed that a “sleight of hand” was used in the computer program that rated 2005 as “THE WARMEST YEAR ON RECORD.” Skeptical climate researchers have discovered extensive manipulation of the data within the U.S. Government’s two primary climate centers: the National Climate Data Center (NCDC) in Asheville, North Carolina and the NASA Goddard Institute for Space Studies (GISS) at Columbia University in New York City. These centers are being accused of creating a strong bias toward warmer temperatures through a system that dramatically trimmed the number and cherry-picked the locations of weather observation stations they use to produce the data set on which temperature record reports are based. The two investigators say the system has been distorted in other ways as well.
NASA’s two primary climate centers, the National Climatic Data Center (NCDC) in Asheville, N.C., and the Goddard Institute for Space Studies at Columbia University in New York City, are accused of “creating a strong bias toward warmer temperatures through a system that dramatically trimmed the number and cherry-picked the locations of weather observation stations they use to produce the data set on which temperature record reports are based.”
Joseph D’Aleo, of Icecap.us, said the analysis found NASA “systematically eliminated 75% of the world’s stations with a clear bias toward removing higher-latitude, high-altitude and rural locations.” The number of actual weather stations used to calculate average global temperatures was reduced from about 6,000 in the 1970s to about 1,500 today. The number of reporting stations in Canada dropped from 600 to 35.
E. Michael Smith, a computer programming expert who worked with D’Aleo, said he found “patterns in the input data from NCDC that looked liked dramatic and selective deletions of thermometers from cold locations.” The more he looked, the more he found “patterns of deletion that could not be accidental.”
Stations in places such as the Andes and Bolivia have virtually vanished, meaning, according to D’Aleo, temperatures from these areas are now “determined by interpolation from stations hundreds of miles away on the coast or in the Amazon.” He says it’s as if Minneapolis stopped reporting and its average temperature was extrapolated from readings in St. Louis and Kansas City.
Smith argues that the decrease in stations used and the selectivity of locations make NASA’s data and conclusions suspect. D’Aleo goes further, saying such cherry-picking and data manipulation are a “scientific travesty” committed by activist scientists to advance the global warming agenda.
