"Elmer Beauregard" of website M4GW has an interesting twist on the temperature reading reliability debate at - Ooops - We forgot Siberia
He claims that temperature readings since 1990 are skewed because the split up of the Soviet Union reduced the number of reporting stations from 15,000 to 5,000. Now this is a very interesting concept. I wonder if it is true?
Can weather station experts answer this question please?
