Climategate Stunner: NASA Heads Knew NASA Data Was Poor, Then Used Data from CRU
Email messages obtained by the Competitive Enterprise Institute via a Freedom of Information Act request reveal that the climate dataset of NASA's Goddard Institute for Space Studies (GISS) was considered -- by the top climate scientists within NASA itself -- to be inferior to the data maintained by the University of East Anglia Climate Research Unit (CRU).
The NASA scientists also felt that NASA GISS data was inferior to the National Climate Data Center Global Historical Climate Network (NCDC GHCN) database.
These emails, obtained by Christopher Horner, also show that the NASA GISS dataset was not independent of CRU data.
Further, all of this information regarding the accuracy and independence of NASA GISS data was directly communicated to a reporter from USA Today in August 2007.
The reporter never published it.
There are only four climate datasets available. All global warming study, such as the reports from the UN Intergovernmental Panel on Climate Change (IPCC), must be based on these four.
They are: the NASA GISS dataset, the NCDC GHCN dataset, the CRU dataset, and the Japan Meteorological Agency dataset.
Following Climategate, when it became known that raw temperature data for CRU's "HADCRU3" climate dataset had been destroyed, Phil Jones, CRU's former director, said the data loss was not important -- because there were other independent climate datasets available.
But the emails reveal that at least three of the four datasets were not independent, that NASA GISS was not considered to be accurate, and that these quality issues were known to both top climate scientists and to the mainstream press.
