Dear Phil, Eystein and Peck,
I've already talked about this to Phil and Keith, but for Eystein's
and Peck's benefit the emails copied below relate to McIntyre
downloading a PDF of a manuscript cited by the IPCC paleo chapter and
then apparently trying to interfere with the editorial process that
the paper is currently going through at JGR.
I think this is an abuse of McIntyre's position as an IPCC reviewer.
Rosanne replied to my email below, to say that they *do* want this
taken further. So...
Phil has agreed to forward these messages to Susan Solomon and Michael Manning.
Eystein and Peck: do you want to add anything too?

>>>and am writing in respect to a submission to your journal by
>>>D'Arrigo et al., entitled "On the Long-Term Context for Late 20th
>>>Century Warming." This article was referenced in chapter 6 of the
>>>Draft IPCC 4AR and made available to IPCC reviewers. In the course

>>>Paleoclimatology. For example, the policy states:
>>>1. Data sets cited in AGU publications must meet the same type of

>>>2. Data sets that are available only from the author, through
>>>miscellaneous public network services, or academic, government or
>>>commercial institutions not chartered specifically for archiving
>>>data, may not be cited in AGU publications.
>>>On page 21 of D'Arrigo et al., there is a listing of "regional
>>>groupings" of data. In some cases, part of the data is archived at
>>>WDCP; in other cases, the data has been collected by the authors,
>>>but has not been archived.

>>> which were used to determine whether this should be applied.
>>>Page 21 � "Due to differing populations in the TR data, the
>>>data-sets were often grouped into 'common' populations. No one
