PRESS RELEASE
PRESS RELEASE � U.S. Temperature trends show a spurious doubling due to NOAA station siting problems and post measurement adjustments.
Chico, CA July 29th, 2012 � 12 PM PDT � FOR IMMEDIATE RELEASE
A reanalysis of U.S. surface station temperatures has been performed using the recently 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. The new analysis demonstrates 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. The paper is the first to use the updated siting system which addresses USHCN siting issues and data adjustments.
The new improved assessment, for the years 1979 to 2008, yields a trend of +0.155C per decade from the high quality sites, a +0.248 C per decade trend for poorly sited locations, and a trend of +0.309 C per decade after NOAA adjusts the data. This issue of station siting quality is expected to be an issue with respect to the monitoring of land surface temperature throughout the Global Historical Climate Network and in the BEST network.
Very groundbreaking -- all of our historical temperature measurement have been skewed in favor of global warming. The AGW proponents sealed in their labs have downloaded this broken data and used it to advance their own agenda.
Again, one of the reasons that WUWT is often a several times/day read for me is that Anthony runs a very tight ship and the signal to noise ratio is very high. On either side of the climate debate, Anthony is consistent in being a clear and verifiable resource for the facts, not the hype.
