Scientists cleared of malpractice in UEA's hacked emails inquiry

Researchers 'dedicated if slightly disorganised', but basic science was fair, finds inquiry commissioned by university

The inquiry panel, led by the former chair of the House of Lords science and technology select committee Lord Oxburgh, was commissioned by the University of East Anglia with investigating the research produced by the scientists at its Climatic Research Unit (CRU).

The work of the unit has come under intense scrutiny since November when thousands of private emails between the researchers were released onto the internet. At a press conference earlier today Lord Oxburgh said, "Whatever was said in the emails, the basic science seems to have been done fairly and properly," although his panel did criticise the scientists for not using the best statistical techniques at times.

The report concluded: "We saw no evidence of any deliberate scientific malpractice in any of the work of the Climatic Research Unit and had it been there we believe that it is likely that we would have detected it. Rather we found a small group of dedicated if slightly disorganised researchers who were ill-prepared for being the focus of public attention. As with many small research groups their internal procedures were rather informal."

The panel was not tasked specifically with looking at the way CRU handled access to its data and Freedom of Information requests from members of the public but it commented that there were "a host of important unresolved questions" arising from the application of FoI to academic research. "We agree with the CRU view that the authority for releasing unpublished raw data to third parties should stay with those who collected it," the report said.

UEA response:

The Oxburgh findings are the result of the latest scrutiny of CRU’s research. The first was the original peer review which led to publication in some of the world’s leading international science journals; the second was the Inquiry by the Parliamentary Science and Technology Committee. Taken together, these must represent one of the most searching examinations of any body of scientific research. The veracity of CRU’s research remains intact after this examination.

It is gratifying to us that the Oxburgh Report points out that CRU has done a public service of great value by carrying out meticulous work on temperature records when it was unfashionable and attracted little scientific interest, and that the Unit has been amongst the leaders in international efforts to determine the overall uncertainty in the derived temperature records. Similarly, the Report emphasises that all of CRU’s published research on the global land-based instrumental temperature record included detailed descriptions of uncertainties and appropriate caveats. We also welcome the confirmation that, although some have accused CRU of trying to mislead, the Unit’s published research emphasises the late 20th Century discrepancy between tree-based proxy reconstructions of temperature and instrumental observations.

The Report points out where things might have been done better. One is to engage more with professional statisticians in the analysis of data. Another, related, point is that more efficacious statistical techniques might have been employed in some instances (although it was pointed out that different methods may not have produced different results). Specialists in many areas of research acquire and develop the statistical skills pertinent to their own particular data analysis requirements. However, we do see the sense in engaging more fully with the wider statistics community to ensure that the most effective and up-to-date statistical techniques are adopted and will now consider further how best to achieve this.

Another area for suggested improvement is in the archiving of data and algorithms, and in recording exactly what was done. Although no-one predicted the import of this pioneering research when it started in the mid-1980’s, it is now clear that more effort needs to be put into this activity. CRU, and other parts of the climate science community, are already making improvements in these regards, and the University will continue to ensure that these imperatives are maintained.
