What a stupid statement! Temperature is very easy to take, make accurate, and calibrate. All you need is some distilled water, a pot, burner, a freezer, ice tray, and a barometer.

As Hugh has already informed you, anyone can quite accurately devise temperature calibration. I used such when I was 13. But my early work in engineering was exactly to the entire process of traceable metrology standards of time, voltage and implicit was temperature. Today, the frequency stability of the GPS system makes all calibration trivial. For example crystals change oscillation frequency with temperatures. If one can count on frequency to parts in a trillion, one can know temperature to parts in a hundreths of degrees. Calibration is about understanding proxi relationships and having one good known physical constant like time or frequency. What I have written is not spin but a simple understanding of applied science. What you have written demonstrates a clear wide and deep ignorance of basic science. Any who do not have a good understanding of basic science cannot have an informed opinion on a complex subject such as global warming analysis.
