After unveiling the Hadley Center adjustment error that has been used in all temperature compilations for the past 20 years, Phil Jones stated:

Climate scientists should think about data quality more often, says Jones, so that there is no opportunity for incorrect data to sow seeds of doubt in people’s minds about the reality of climate change.

This is the same Phil Jones who said:

We have 25 or so years invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it. There is IPR to consider.

Peter Webster, like Hans von Storch before him, was nonplussed at this attitude and, at his request, I provided the supporting email in a comment on another thread, noting that von Storch, also in disbelief, had contacted Phli Jones directly for confirmation, obtaining such personal confirmation, which von Storch had then reported to the NAS panel, as I discussed here, linking to von Storch’s PPT.

During the past few years, I’ve posted progress reports on CRU’s obstruction of efforts to find out even the simplest information about how they do their calculations - things as simple as a list of stations in their temperature calculations. These progress reports are scattered through many posts and I’ve collated into a PDF online here, covering two topics:

1) efforts to identify the station data used in CRU temperature analyses, and, once that had been refused, efforts to obtain even a list of stations used by SRU. Two generations of inquiry are shown, first by Warwick Hughes in 2005 and then by Willis Eschenbach in 2006-2007, which after 3 years and countless attempts only resulted in a not quite complete list of stations.

2) efforts to obtain a list of stations used in Jones et al 1990, a prominent study purportedly proving that the UHI effect was inconsequential. Once this list was obtained, an examination of the list of Chinese stations by myself and Doug Keenan, showed that claims in Jones et al 1990 to have selected stations based on careful examination of station history metadata could not possibly be true, as such metadata did not exist, which led Keenan to file a complaint against one of the authors.

This collation draws on previous posts at Climate Audit and my correspondence files.  Source
