In 2007, the following paper exposed the whole business:
Keenan, D.”The Fraud Allegation Against Some Climatic Research of Wei-Chyug Wang. Energy and Environment, 18, 985-995.
The author Keenan obtained the original Chinese data and found the claim that the data referred to a continuous series was unfounded. He accused Wang of fraud — and it is interesting to read that Tom Wigley (of the CRU emails) agrees with him.
Wigley fails to say, however, that his colleagues Jones and Karl are guilty of much worse than Wang — as they continued to use their fraudulent paper to boost their constant and sometimes daily assertion that recent global temperatures are unprecedented.
Wang was cleared of fraud by his university. But what about Jones and Karl?
In 1999, I had a stroke of luck. I asked one of the IPCC officials for the data from which one of their maps was compiled, and I received it. I wrote a paper analyzing the results and submitted it to Geophysical Research Letters. They just sat on it. I instead published it on John Daly’s website. Today, it is still the only paper recognized by Google on “Regional Temperature Change.”
I now know my paper was not critical enough, since we have proof that the basic data and its processing is far more dubious than I had envisaged.
I tried to update my paper and resubmit it. Nothing doing. Since the small group — revealed within the CRU emails — control most of the peer reviewers, very few peer reviewed papers which criticize that group are allowed to appear in the most prominent published literature which dominates the academic establishment.
I have only been able to find a place to release my criticisms on the internet, now the only realm where unfettered scientific discussion is possible.
