New Study Disputes NOAA’s Evidence on Climate Change

by Pat Horan

Yesterday, Anthony Watts of Watts Up With That? released a scientific discussion paper that calls into question the data used by the National Oceanic and Atmospheric Administration to suggest climate change is a reality.

The paper, co-authored with Dr. John R. Christy of the University of Alabama at Huntsville, Stephen McIntyre of Toronto, Canada, and Evan Jones of New York, concluded that “reported 1979-2008 U.S. temperature trends are spuriously doubled, with 92% of that over-estimation resulting from erroneous NOAA adjustments of well-sited stations upward.”

In a press release issued from his offices in Chico, California yesterday, lead researcher Anthony Watts explained the significance of the new standards and the resultant findings of the study:

“A reanalysis of U.S. surface station temperatures has been performed using the recent WMO-approved Siting Classification System devised by METEO-France’s Michel Leroy. The new siting classification more accurately characterizes the quality of the location in terms of monitoring long-term spatially representative surface temperature trends…

“Today, a new paper has been released that is the culmination of knowledge gleaned from five years of work by Anthony Watts and the many volunteers and contributors to the SurfaceStations project started in 2007.

“This prepublication draft paper, titled An area and distance weighted analysis of the impacts of station exposure on the U.S. Historical Climatology Network temperatures and temperature to be submitted for publication [in an academic journal]. . .” 

Using Leroy 2010 methods, [this paper] concludes that these factors, combined with station siting issues, have led to a spurious doubling of U.S. mean temperature trends in the 30 year data period covered by the study from 1979-2008.
