The UK's MET Office has information it does not want to disclose...

The Meteorological Office is blocking public scrutiny of the central role played by its top climate scientist in a highly controversial report by the beleaguered United Nations Intergovernmental Panel on Climate Change.

Professor John Mitchell, the Met Office’s Director of Climate Science, shared responsibility for the most worrying headline in the 2007 Nobel Prize-winning IPCC report – that the Earth is now hotter than at any time in the past 1,300 years.

And he approved the inclusion in the report of the famous ‘hockey stick’ graph, showing centuries of level or declining temperatures until a steep 20th Century rise.

By the time the 2007 report was being written, the graph had been heavily criticised by climate sceptics who had shown it minimised the ‘medieval warm period’ around 1000AD, when the Vikings established farming settlements in Greenland.

In fact, according to some scientists, the planet was then as warm, or even warmer, than it is today.

Early drafts of the report were fiercely contested by official IPCC reviewers, who cited other scientific papers stating that the 1,300-year claim and the graph were inaccurate.

But the final version, approved by Prof Mitchell, the relevant chapter’s review editor, swept aside these concerns.

Now, the Met Office is refusing to disclose Prof Mitchell’s working papers and correspondence with his IPCC colleagues in response to requests filed under the Freedom of Information Act.

The block has been endorsed in writing by Defence Secretary Bob Ainsworth – whose department has responsibility for the Met Office.

Documents obtained by The Mail on Sunday reveal that the Met Office’s stonewalling was part of a co-ordinated, legally questionable strategy by climate change academics linked with the IPCC to block access to outsiders.

Last month, the Information Commissioner ruled that scientists from the Climatic Research Unit at the University of East Anglia – the source of the leaked ‘Warmergate’ emails – acted unlawfully in refusing FOI requests to share their data.

Some of the FOI requests made to them came from the same person who has made requests to the Met Office.

He is David Holland, an electrical engineer familiar with advanced statistics who has written several papers questioning orthodox thinking on global warming.

The Met Office’s first response to Mr Holland was a claim that Prof Mitchell’s records had been ‘deleted’ from its computers.

Later, officials admitted they did exist after all, but could not be disclosed because they were ‘personal’, and had nothing to do with the professor’s Met Office job.

Finally, they conceded that this too was misleading because Prof Mitchell had been paid by the Met Office for his IPCC work and had received Government expenses to travel to IPCC meetings.
