Thanks Keith,
Wow--you're echoing my thoughts exactly. I really can't believe Nature published this. The
problems seem to jump out at you when you read what they've done. I can only assume that
the borehole folks and Von Storch and company pushed this (as reviewers, or otherwise).
Heike Langenberg was a von Storch post-doc, but she's always struck me as honest and
independent--I'd hate to think otherwise...
I'm doing some experiments right now w/ CCSM3 pseudoproxies emulating what they've done as
we speak. I'll plan to send these to you guys and Phil, as soon as I've got some results.
We could join efforts in a response, or both write separate responses. Whatever you think
makes more sense. In any case, I want to show you guys the results and get your thoughts...
Thanks again,
Mike

thanks for this . I have to say that I do not think the Moberg paper advances the
Science much. Need to see supplementary information , but my initial thought is that
there are real problems with their treatment of the "low frequency data" . We are
weighed down with trying to put a large European proposal together , but Tim and I are
toying wit the idea of writing a response. I find it a bit irritating that they couch
their piece as a specific criticism of the M+J series and virtually ignore the other
reconstructions , hence setting up a straw Mann (ha ha) . Problem is that thsi
juxtaposition of boreholes ,Echo-G and their series will create a new "state of the art"
of (apparently) mutually reinforcing evidence. At 12:49 09/02/2005, you wrote:

Hi Keith,
Thanks for the clarification.
I have seen the zero order draft and have looked over it, though not yet in full detail.
On the whole appears quite fair, and balanced, and comprehensive. Very nice job!
I still think the borehole discussion is a bit unbalanced. It sounds a lot like Henry
Pollock to me. The Gonzalez-Rouco simulation is, as we know, somewhat questionable, and
there is no discussion of the GISS simulation by Mann and Schmidt which suggests a
likely low-frequency bias. So I'm likely to comment on this in my "official" remarks as
a reviewer for the chapter (seems a bit odd that I'm both a contributor and reviewer,
but as long as you all don't mind, I don't either). Other than that, I think my comments
will probably be minor (you know how rare that is!).
I see that the comments are due in early April, so I'll probably wait until it gets
close so that I can provide an update on the status of in-review/in-press manuscripts.
For example, I'm hoping to work w/ Phil on a sort-of response to Moberg et al, which
should be quite clarifying (we can get the same result as them, basically, using the
Mann and Jones series and a similar approach to what they did, but I think I can show
that the approach does very poorly w/ pseudoproxies). By the way, the Mann et al J.
Climate letter on the CCSM Pseudoproxy experiments in now provisionally accepted. Will
keep you updated.
Thanks again for keeping me updated, and congratulations on a wonderful job w/ the ZOD.
Its an improvement on what we had in the TAR for sure, and I really like the fact that
it gives justice to the large amount of work that has been done by the community since
then...
thanks again,
mike

Sorry !!!!!!!!!!!!!!!! You can see that I am in "headless chicken mode" - no idea how
this message got reworked into my inbox! Have you seen the zero order draft ? Where
are we with balancing views?

HI Keith,
Thanks--this is a very old message. I think we provided this abstract many months ago
already. SO, unless I misunderstand, nothing for us to do here, I think??

Dear Keith,
No doubt you got the reminder that the CLIVAR folks want a (400 word) abstract from us
by Dec 15th for the June meeting. Did you want to take the first stab at this, then we
can iterate back and forth a bit?
let me know how you want to proceed w/ this...
Thanks,
mike
