Apparently Mr. Connolley has edited 5428 Wikipedia articles, most about climate. Die Kalte Sonne:
Unbelievable but true: The Wikipedia umpire on Climate Change was a member of the UK Green Party and openly sympathized with the views of the controversial IPCC. So it was not a referee, but the 12th Man of the IPCC team.
I'm not sure how accurate the translation is, but it suggests he was somehow part of the IPCC "short list" team. See it here at Die Kalte Sonne via this
Google Translate link.
With over 5000 articles he's edited, it makes you wonder if Mr. Connolley was employed by someone or some organization specifically for the task.

Comment: A 2009 report revealed that a British scientist and Wikipedia administrator rewrote climate history, editing more than 5,000 unique articles in the online encyclopedia to cover traces of a medieval warming period - something Climategate scientists saw as a major roadblock in the effort to spread the global warming message. Connolley, one man in the nine-member team who is a U.K. scientist, a software engineer and Green Party activist, took control of Wikipedia's entries to see that any trace of the true climate history would be erased.
