The climate change hoax

Global warming is probably one of the most contentious issues currently.
Al Gore’s film, “An Inconvenient Truth,” documents his belief that humans are the cause of this warming and of an impending catastrophe on the planet. Therefore, many experts call for reduction of greenhouse gas emissions, such as carbon dioxide.
Dissenting experts claim that global warming is cyclical as evidenced by the several historical ice ages and periods of warming. They also point out that the increase in carbon dioxide has always followed periods of warming rather than being caused by the warming.
In order to substantiate the claim for global warming, accurate historical data must be available. Weather data has been recorded and collected by the National Weather Service. Its U.S. Historical Climatology Network is comprised of 1221 reporting stations within the 48 contiguous United States. These records generally include the period 1900 – 1995. Each station is subject to certain quality-control and homogeneity testing and adjustment procedures. If the data is not reported, it is filled in with data from other nearby sites. Obviously, this can and has introduced major errors in temperature readings.
The National Weather Service through the National Oceanic and Atmospheric Administration has also established standards for the proper siting of the reporting stations and the sensors. They define five classes of sites:
Class I – Sensors are located at least 100 meters (330 feet) from artificial heating or reflecting surfaces, such as buildings, concrete surfaces, and parking lots.
Class 2 – Artificial heating sources are located 30 meters (100 feet) away from sensor.
Class 3 – Artificial heating sources are located 10 meters (33 feet) away from sensor. Introduces an error of 1°C
Class 4 – Artificial heating sources are less than 10 meters (33 feet) away from sensor. Introduces an error greater than 2°C.
Class 5 – Temperature sensor located next to or above an artificial heating source, such as a building, rooftop, parking lot, or concrete surface. Introduces an error greater than 5°C.
I went to observe two of the1221 climate-reporting stations. The one in Paso Robles has placed the sensor on a concrete pad, with cars parked against the pad and a building next to it. In addition, it is located next to a major city street with constant heavy automobile traffic. Consequently, the readings from this reporting station have been high, showing an error greater than 5°C or approximately 8°F for several years. It is most disturbing to realize that erroneously high readings from stations like this have been used by climatologists to claim man-caused global warming.
Cal Poly also has a climate-reporting station. Its sensor is located five feet from the gravel road and 40 feet from a concrete walkway next to buildings. However there are broken down RVs right next to the sensor. One of them has been sitting there for several years as a heat sink. In addition, there are several chemical test pools between 100 and 200 feet away.
Both of these stations fail NWS’ own standards and reporting procedures. In fact, research done by Meteorologist Anthony Watts of “SurfaceStations.org” shows that almost 90% of the 1221 stations report rising temperatures because they are badly sited. It shows that the data has been seriously erroneous. The temperature readings have been consistently too high.
The foundation for the claim for man-made global warming which is based on historical data gathered from San Luis Obispo County’s two reporting stations is fallacious. Unfortunately, the reported temperature data, not the earth, is cooked by man.
