News broke on or around 19 November 2009 that a large archive of emails and files from the Climatic Research Unit (CRU) in the UK had been released on the internet. The contents of the files were sufficiently disconcerting to the public, governments and university administrations that a number of inquiries were established. Several of my research projects were discussed not only in the so-called “Climategate” emails themselves, but also in the investigations, and I made detailed submissions of evidence to three of the panels. Consequently I take considerable interest in the outcome of these inquiries, especially with regards to whether they approached the issues impartially, investigated thoroughly and drew valid conclusions that fully reflected the evidence.
