Hi Ed and Keith - I hate to say it, but Richard's take on the
political aspects of the NRC vs. IPCC reports seem worth some extra
effort. Since you were both invited to speak with the NRC committee,
I would suggest that you both (together or separately) submit formal
comments asap. I don't know when the comment period starts or ends,
but I'm guessing you have to work fast. I'm also thinking that you
two might want to get out a peer-reviewed paper on the topic really
soon too. I worry that the hole will continue to deepen for
dendroclimate if you two don't act to clarify what we know/don't
know, and when it is safe (and why) to use dendroclimate data to
address the issue of long-term variation in temperature.

Please don't construe my suggestions or comments as pro/con dendro,
but rather just as someone who wants the truth - whatever it is - to
be communicated clearly, and as best we know it. But, I do think that
if Richard is suspect, dendro has a real problem. He doesn't have a
personal bias in this, and is clearly trying harder than most to
understand what's really going on with climate and the proxies.

Effort now might save time later.

Also, are you both going to be at the Swiss mtg in June? We really
have to get this all ironed out better before the next (last) draft
of the IPCC AR4.

Thanks, Peck
