Don Keiller is the Deputy Head of Life Sciences at Anglia Ruskin University in Cambridge where he is listed as the Programme Leader for Biomedical, Molecular & Sports Science. He has conducted biochemical research, photobiology, and has worked with the Cambridge University Department of Plant Sciences.

His interest in climate change, he says, appeared when after concerns were first raised about the environmental effects of the Ozone Hole.

Keiller has been critical of the University of East Anglia's Climate Research Unit (CRU), and submitted a memorandum to parliament requesting the CRU where he contends that “Professor Jones and colleagues at CRU conspired to obstruct reasonable and legitimate requests for access to scientific data.” He was one of the individuals who used the F.O.I. Act to request data from CRU. [2]

Stance on Climate Change

Keiller has said that climate change “is happening, but not catastrophic and not primarily CO2 driven.” [3]

Key Quotes

“All to often we hear that there is a scientific 'consensus' on climate change and its causes. If this were the case why then is increasing evidence to the contrary being published in peer-reviewed scientific journals?” [4]

“What these emails reveal is a detailed and systematic conspiracy to prevent other scientists gaining access to CRU data sets. Such obstruction strikes at the very heart of the scientific method, that is the scrutiny and verification of data and results by one's peers.” [5]

Key Deeds

Keiller has been critical of the scientists at the centre of the CRU hack. He claims that Professor Jones and his colleagues conspired to withhold information that could have been used to criticize them.  [5]

One of the hacked emails was from Keiller himself. In an e-mail to Keith Briffa, Keiller describes himself as an 'environmental plant physiologist' and writes that “Given the scientific, political and economic importance of these papers, further detailed explanation is urgently required.” [6]

In another e-mail to Briffa, Keiller says “I find your explanations lacking in scientific rigour and I am more inclined to believe the analysis of McIntyre,” sand links to the website Climate Audit. He is most likely referring to Steve McIntyre, ex-mining industry executive and founder of the Climate Audit blog. McIntyre's eduction is in Philosophy, Politics, and Economics, not climate change.

Keiller has submitted at least eight separate submissions to the Muir Russell Climategate Enquiry:

He also submitted a Memorandum to the UK Parliament where he asserts that the CRU e-mails reveal a “detailed and systematic conspiracy.” Keiller believes that until the CRU's data in its entirety is released to the public, “all peer-reviewed publications whose conclusions rely on CRU's temperature records must be withdrawn as 'unproven',” and that “all policy decisions based on this data and conclusions drawn from it are also unsafe, until proven otherwise.” [2]

In July, 2011, the CRU released temperature records going back 150 years from 5113 weather stations around the world.  [7]

Trevor Davies, the university's pro-vice-chancellor for research had the following statement: “We released [the dataset] to dispel the myths that the data have been inappropriately manipulated, and that we are being secretive. Some sceptics argue we must have something to hide, and we've released the data to pull the rug out from those who say there isn't evidence that the global temperature is increasing.”



Keiller's profile at the Anglia Ruskin University lists 20 publications, primarily in the area of plant sciences. He has not published any articles in peer-reviewed journals on the subject of climate change, and does not appear to have any background in this area.
