Thanks for the advice Phil. I'm aware that these guys would like nothing
better than to trap me in an ongoing back-and-forth, waste my time, and use
anything I say against me later on. So, I responded only after careful
consideration, and intend to follow through on my vow to not engage in
further exchanges. My words were quite measured (as I'm sure you're aware,
knowing the kinds of emails I'm capable of firing off!), and I hope I
corrected the record for those who are willing to listen. Unfortunately,
many of them aren't I'm sure. But at least we've put the truth out there.
There were some
influential types in that list (e.g., congressional senate committee
advisers) so in part, I wanted to make sure they knew that these guys are
distorting the

Chick Keller and others have been helpful in taking up some of the slack too,
but it's easy to waste one's time with this. I'll need every minute I've
got next month when I begin to teach my course, and the avalanche of IPCC
reviews is upon me!

talk to you soon,

As you aptly note, the converse of the statement I made isn't quite true.
ie, not all records that we did use *were* in the public domain, although
I believe we used just about all of the records that were (which is the
statement I was making).

I think you guys know that I find the "data witholding" silly, and if it
were up to me you would have every single record we have. It is
particularly irking to me to not be able to give them to you, because I
know that the key ones you're thinking of (morroccan dendro) don't amount
to a hill of beans in the end [I did the reconstructions ommitting those
data a couple years back, to convince myself that the difference was
negligible], and until we have access to identical datasets, our
comparisons are going to be apples-and-oranges, which helps nobody. So I'm
going to push Malcolm on this. Perhaps, over beers next week at AGU, and I
can convince him to convince Stockton to allow these to be distributed.

That having been said, when Tim comes to visit (hopefully in June--need to
get back to him!) and works on our computer, and on the planned
cross-comparisons, I'm not going to be policing what data he does and
doesn't have access to.
So it will be in his hands, and he'll be able to do with it what he may.
It's just that, for cover, I cannot have officially "given him" the data...
