Dear Keith,

Let me start out by apologizing. Meant to get in touch w/ you
several weeks ago but forgot. I was hoping you would be willing
to act as a contributor on the IPCC report for the climate variability
and change chapter which I'm a co-lead author on.

We've already solicited from Phil a discussion of the various hemispheric
temperatures reconstructiosn, etc., but I was hoping you could provide
some discussions about two specific topics related to your recent work
(and any other related work that is relevant).

1) the reduced sensitivity of high-lat dendro indicators in recent decades

and

2) the detection of volcanic events (based on dendro and otherwise).


Just a few paragraphs, and perhaps a figure if especially helpful, would
be great. We have a Feb 20th deadline for preparation of the rough draft,
so if you could do this within the next 1-2 weeks that would be very
helpful.

SOrry again for the lateness of this message. I'm hoping it isn't too
late to get this valuable contribution from you!

thanks in advance for any help you can provide.

Hoping to see you one of these days!

cheers,

mike.
