IS CLIMATEGATE finally over? It ought to be, with the publication of the third UK report into the emails leaked from the University of East Anglia’s Climatic Research Unit (CRU). Incredibly, none looked at the quality of the science itself.

The MPs’ inquiry – rushed out before the UK general election on 6 May – ducked the science because the university said it was setting up an “independent scientific assessment panel” chaired by geologist Ron Oxburgh.

After publishing his five-page epistle, Oxburgh declared “the science was not the subject of our study”. Finally, last week came former civil servant Muir Russell’s 150-page report. Like the others, he lambasted the CRU for its secrecy but upheld its integrity – despite declaring his study “was not about… the content or quality of [CRU's] scientific work” (see “Scientists respond to Muir Russell report”).

Though the case for action to cut greenhouse gases remains strong, this omission matters. How can we know whether CRU researchers were properly exercising their judgment? Without dipping his toes into the science, how could Russell tell whether they were misusing their power as peer reviewers to reject papers critical of their own research, or keep sceptical research out of reports for the Intergovernmental Panel on Climate Change?
