hi Rob -

i am leary of passing all of this around but in
this case i am glad in that osborn et al
need to know what is going on - they should fire
him as a reviewer of IPCC - i cant
believe they included him in the first place! So,
please email him back and tell him that he
should as he says take it up with the ipcc
authors and see whether it is still appropriate to
include him as a reviewer.

we should however be very cautious about our
emails, lord v will stop at nothing (this
is sort of fun in a harry potter way)...

>>>
>>>Data Citation and Archiving
>>>I point out that AGU policies for data
>>>citation and data archiving
>>>(<http://www.agu.org/pubs/data_policy.html>http://www.agu.org/pubs/data_policy.html

>>>Center for Paleoclimatology. For example, the
>>>policy states:
>>>
>>>
>>>1. Data sets cited in AGU publications must

>>>literature. Thus data cited in AGU
>>>publications must be permanently archived in a

>>>2. Data sets that are available only from the

>>>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

>>>
>>>In cases, where the data has been archived, it

>>>For example, the Torntraesk site is presumably

>>>russ021w, russ176w and russ022w, but this is

>>>Icefields site is again a different version

>>>Seward, NW North America, Central Alaska,

>>>In order that this submission comply with AGU

>>>This bias was assessed by correlation and

>>>
>>>
>>>
>>>Page 21 � "Due to differing populations in the
>>>TR data, the data-sets were often grouped into
>>>'common' populations. No one strategy is
>>>appropriate for all data-sets and careful
>>>evaluation of each composite data-set was
>>>made." That's nice, but what were the
>>>operational criteria which were used to
>>>allocate each case to the 5 different
>>>alternative procedures.
>>>
>>>
>>>Page 7 � "The standard error of the regression
>>>estimate (standard deviation of the regression
>>>residuals) from the full period calibration
>>>was used to generate the 2 sigma error bars
>>>and this was also adjusted (inflated) to
>>>account for the change (decrease) in explained

>>>Page 20. "Successful modeling of paleoclimate

>>>amplitudes and variability." Abstract �
>>>"presently-available paleoclimatic
>>>reconstructions are inadequate for making
>>>specific inferences, at hemispheric scales,
>>>about MWP warmth relative to the anthropogenic

>>>still be made at the local/regional scale."
>>>Page 13. "After this period [mid-1980s], the
