Here are a couple of reports regarding the Jones position:

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.
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.

Excerpt:
Examination of the data shows that almost all of the 1901-1996 temperature rise for Russia/Soviet Union took place in one year, 1987 to 1988. Table 3 gives the details. The average rise for the whole of the region was 1.21°C which contributes 0.16°C to the Northern Hemisphere for that year, and 0.10°C to the Global temperature increase. Since the recorded temperature increase for the Globe is 0.02°C, this means that without the Russian figure, there would have been a fall of 0.08°C.

Karl’s data show that there are large differences in the temperature change from 1901 and 1996 between different regions on the earth’s surface. Individual 5°x5° grids .ranged between -2.12°C in the Greenland Sea and +.4.06°C for Spitzbergen (only 1500 km away) Larger regions ranged from -0.46°C for Bolivia to +1.30°C for East Siberia.. One has to question whether studies based on only a few regions, for example those from ice cores or tree rings, can give an adequate estimate of global temperature change.
There is only a slight difference between the Northern and the Southern Hemisphere, but is this apparent agreement real? Only 31.4% of the Southern Hemisphere had acceptable measurements.
The most comprehensive series of measurements were those made in the Atlantic Ocean. Here there was a marked positive temperature change gradient between the north and the south; from -0.11°C for the North Atlantic, to 0.64°C for the north east Atlantic, to 0.44°C for the Middle Atlantic, 0.75°C for the South East Atlantic and 0.84°C for the South East Atlantic. There is a similar positive gradient between the Arabian Sea/ Bay of Bengal (0.53°C) and the sea route Capetown to Australia (0.91°C)
