Nothing about the revelations surprises me. I have maintained email correspondence with most of these scientists for many years, and I know several personally. I long ago realized that they were faking the whole exercise.
When you enter into a debate with any of them, they always stop cold when you ask an awkward question. This applies even when you write to a government department or a member of Parliament. I and many of my friends have grown accustomed to our failure to publish and to lecture, and to the rejection of our comments submitted prior to every IPCC report.
But only recently did I realize that I had evidence of their fraud in my possession almost from the birth of my interest in the subject.
I had copies of these two papers in 1990:
Jones, P. D., P. Ya. Groisman, M. Coughlan, N. Plummer, W. C. Wang & T. R. Karl 1990. Assessment of urbanization effects in time series of surface air temperature over land, Nature 347 169- 172.
Wang, W-C, Z. Zeng, T. R Karl, 1990. Urban Heat Islands in China. Geophys. Res. Lett. 17, 2377-2380.
The first paper has been the major evidence presented by Jones in all of the IPCC reports to dismiss the influence of urban change on the temperature measurements, and also has been used as an excuse for the failure to mention most of the unequivocal evidence that such urban effects exist. The paper was even dragged out again for the 2007 IPCC report.
The second paper, which shared authors Wang and Karl from the first paper, used the very same data from China which the first paper used to demonstrate the absence of urban influence — yet instead concluded that same data to be proof of the existence of urban influence.
