A fresh tranche of private emails exchanged between leading climate scientists throughout the last decade was released online on Tuesday. The unauthorised publication is an apparent attempt to repeat the impact of a similar release of emails on the eve of the Copenhagen climate summit in late 2009.
The initial email dump was apparently timed to disrupt the Copenhagen climate talks. It prompted three official inquiries in the UK and two in the US into the working practices of climate scientists. Although these were critical of the scientists' handling of Freedom of Information Act requests and lack of openness they did not find fault with the climate change science they had produced.
Norfolk police have said the new set of emails is "of interest" to their investigation to find the perpetrator of the initial email release who has not yet been identified.
The emails appear to be genuine, but the University of East Anglia said the "sheer volume of material" meant it was not yet able to confirm that they were. One of the emailers, the climate scientist Prof Michael Mann, has confirmed that he believes they are his messages. The lack of any emails post-dating the 2009 release suggests that they were obtained at the same time, but held back. Their release now suggests they are intended to cause maximum impact before the upcoming climate summit in Durban which starts on Monday.
