honestly just a cross thread between Tom and I. I had been asked by
Darrell whether we should use the Sidorova chronology - because of
hassle by you know who - so asked Tom a while ago to ask you. I did
not see your answer - sorry if you cc'd me in as I have not been
checking emails. I fully accept and would NEVER go behind your back
to ask for the data. I understood that the chronology was published
and so thought to compare our RCS version with it if we could produce
it in time . We are being accused of not using that chronology in the
Science paper- so then asked Anders for it. I am happy to send
Darrell the single chronology if that is what Anders has sent. I am
having to start thinking about the Yamal crap and then this Darrell
stuff suddenly arises. I just wanted him to consider including the
Polar Urals reconstruction and the Sidorova series in his analysis
before publishing a correction in Science- apparently the selection
criterion for inclusion of series was anything published north of 60
degrees and longer than 1000 years. I could do without all this now -
don't really understand what Climate Audit are getting so hysterical
about but feel that I can not ignore it this time - but don't feel up
to getting involved. I fully admit to being out of the loop as
regards all this and having trouble getting back to it.

To restate - this was a confusion. I fully accept your point (as you
know I would). Sorry if you thought I was doing anything without your
knowledge - TO BE HONEST ALSO - I actually was not really aware that
the data you were producing and that used by Sidorova were one and
the same. Best wishes hopefully all ok
I assume that we are allowed to use the chronolgy as published - are
we? I have not contacted Sidorova. Can you cc answer to Tom as I have
no email at present. (this coming from someone elses computer)
