US Temperature Records Biased on High Side
By Richard Henry Lee

10 May 09 - (Excerpts) - After surveying 70% of the 1,221 weather
monitoring stations in the US, Anthony Watts of the Watts Up With That
website, finds that the temperature record is “unreliable”. About
90% of the stations are
sited poorly, such as being surrounded by asphalt parking lots which
act as heat islands. The result is that most stations are reporting
“higher or rising temperatures” due to poor siting alone, according to
Watts.
The US surface temperature record is one indicator used for making claims about global warming.
Anthony Watts and his volunteer army numbering 650 performed yeoman’s work in amassing this data. The results are chronicled at Watts’ website at SurfaceStations.org. The project was funded entirely by volunteers without corporate or government assistance.
These results also provide additional evidence that the science of global warming is not settled, and that we should not embark on a costly efforts to control CO2 emissions when the underlying data is faulty.
But the real question is why it took a dedicated group of volunteers to find the numerous faults in our temperature record rather than the heavily funded governmental and educational institutions which are continually warning us about global warming.
Dear Robert,

"This was a bit of a shock to me; that the weather data collecting
stations are often located in parking lots, covered with heat trapping
asphalt, and that the data collected from them is somewhat faulty.
