DATA on global temperatures is compiled by several organisation including NASA’s Goddard Institute for Space Studies (GISS) headed by James Hansen. This data set tends to show more warming than, for example, data compiled by the UK Meteorology Bureau’s Hadley Centre. Both rely on measurements from thermometers.
All sorts of statistical tests can be performed on data – on numbers. There is even a test to determine whether data is likely to have been ‘massaged’ by people.
Ecologist and computer modeller David Stockwell has used this technique to analyse the frequency of the final digits in the temperature data compiled by James Hansen’s team, and he claims that the unequal distribution of the individual digits strongly suggests manipulation. Read more here.
After receiving his Ph.D. degree in Ecosystem Dynamics from the Australian National University in 1992, Dr Stockwell worked as a consultant until moving to the San Diego Supercomputer Center at University of California San Diego in 1997. There he continued his work developing computational and data intensive methods of ecological niche modeling using museum collections data. Dr Stockwell has received grants from the NSF, USGS and DOT enabling him to develop software such as GARP (Genetic Algorithm for Rule-set Production) used in making outstanding contributions in many fields: modeling of invasive species, epidemiology of human diseases, the discovery of seven new species of Chameleon in Madagascar, and effects on species of climate change. Dr. Stockwell has published research articles in the major international journals Nature, Ecological Modelling, and the International Journal of Geographic Information Systems. He was recently judged by the US Immigration Service as an Outstanding Researcher, a category reserved for persons recognized internationally as outstanding in their academic field.
