The Canadian Government is eager to implement the Kyoto Accord. It is my contention that this accord is flawed due to technical temperature monitoring consideration, that have yet to be taken into account. There is evidence that the temperature devices used for weather observation is the very same RTD used in our industry.
I would appreciate your considered critiques of my position as outlined below.
My thanks in advance

Accuracy of Resistance Temperature Detectors and Global Warming
Flawed observations result in flawed conclusions.
Fact - Scientific conclusions are based on theory supported by direct observation.
Theory - Some scientists and many special interests have postulated that the Earth's temperature has risen by one degree (Celsius?) over the last century.
Conclusion - There can be no empirical evidence to support a claim of one degree of warming over the last century. All observations of temperature are based on mechanical devices which have uncertainty of reading greater than plus or minus one degree Celsius. Therefore the projections, assumptions and computer models based on these observations have the same, or greater, uncertainty. In fact, the Earth today could very well be colder by one degree than it was a century ago.
Summary - Uncertainties associated with the devices used to measure temperature are in the order of plus or minus one degree Celsius at the
best of conditions. The best conditions are measurements at the freezing point of water after proper, structured calibrations are carried out. Temperatures higher or lower than freezing have a corresponding additional
uncertainty.
Outside of the laboratory, adding the uncertainty of measurement for the temperature element and the associated electronics that are attached, the measured uncertainty can be significantly higher than plus or minus one degree. In fact, Fluke Technology, makers of temperature reading systems presented a paper in the early 90s that stated that no one could be sure of temperature readings without adding a plus or minus TWO degree Celsius to the reading. In other words, if you are reading 25 degrees Celsius the reading may be between 23 and 27. This is four times the "calculation" of the last century's temperature rise proposed by Global Warming supporters.
There is another wrinkle affecting accuracy with world wide temperature readings. The temperature element used is not a linear device. An algorithm is built into the electronics monitoring the temperature element to correct this physical phenomenon. I understand that Europe uses a different algorithm than does North America.
