Yes, this change sounds great and most appropriate Mike.

thanks...Julie BG (from Salt Lake)

Christoph,
Looks pretty good in general, but there is big problem in wording here:

* Late 20th century warming is most probably anomalous regarding the past 1000 years.
However, due to the much sparser network, and generally unreliable character of proxy
data compared to the modern instrumental network, a solid conclusion about the
uniqueness of the recent warmth cannot yet be definitive.

I don't think that this group would agree that "generally unreliable character" is an
appropriate description. I would suggest something more akin to the following, and would
be interested in any other thoughts be have on this:
Late 20th century warming is likely anomalous in the context of the past 1000 years.
However, due to the much sparser available data, and the more uncertain character of
proxy data compared to the modern instrumental network, a more definitive conclusion is
not yet possible.
thanks,
mike

Dear all,
After including your comments, the document regarding "Past Millennia
Variability" increased in length :-)!
Thanks a lot for your edits.
It is the idea to use this statement as a "working-basis" for a planned
related workshop under the umbrella of PAGES-CLIVAR.
Finally (after a wider discussion) a revised version may become a background
statement for future research activities.
Feel free to send me your comments.
All the best and greetings from the PAGES office in Bern,
Christoph
