More on the SBC – Horse Puckey Sierra Warming

Several years ago with Ellen and I were helping Anthony Watts with his Surface Station Project, and I miss identified the Quincy CA Surface Station. It was a Sunday, could not find station and asking around at the police station were told it was at the Ranger Station. We visited the Station and a Ranger took us to a Remote Automated Weather Station (RAWS) on the hill behind the station. Antony later found the real station, behind the radio station.
This Quincy was rather remote, and would not have been influenced by an urban heat island, and I thought it would be a good reference station to see if in fact the Sierra was warming and the warming was accelerating as claimed by Steven Frisch.
Here is a plot of the average annual temperatures from 1991 to 2010, the years with a complete record.
As you can see the temperatures vary from year to year, but according to the regression analysis the temperatures are essentially flat for the 19 years examined. It appears that from about 2002 to 2010 the temperatures have been in declining year over year. We need about 30 years to establish a more definitive trend.
Bottom line, there no evidence of accelerated warming in the Sierra warming, unless Mr. Frisch has some stronger evidence.
