A batch of Michael Mann’s emails have been released, following a request and legal action, see here for background.
The emails are available at this link.
There are 728 emails or they can be arranged in 361 threads, covering a period from 1999 to 2005. Quite a lot of them are already public knowledge thanks to Climategate, but there are also a lot that aren’t.
Tom Nelson and Bishop Hill have some comments on twitter under the #mannemail tag.
I doubt whether there will be any stunning new revelations.
