Well, apparently there _is_ a recent U AZ project that explicitly addresses
the question. This at least takes some of the heat off Austin @ csu-pomona.

I would still very much like to know who did the study and what they
actually concluded. The press habitually mixes up "no evidence for A"
with "evidence for not A", with A in this case being global warming. It is
entirely possible that one of the participants in the study feels that "not A"
and is pitching this angle to the press with carefully chosen words that
the press proceeds to garble. I've seen this phenomenon before.. Did the News
mention a name or a journal for the actual study? (wishful thinking)

I'd like to see this study since it seems it is going to be much quoted
in the debate. I certainly don't wnat to dismiss its findings, if at all,
before I know what they actually are and how they were obtained.

In particular I'd like to know whether the word "inevitabl[y]" came from
the newspaper or the researchers. I rather doubt it's the latter! Scientists
rarely use that word in public!

Of course, defining "apocalyptic version" as the version so pessimistic
that it exceeds the expectations of five sixths of all climatologists
is sufficient to guarantee that the statement is true. But really this
latter paragraph if quoted correctly and without omission constitutes an
unwarranted and irresponsible slanting of the views of the climatological
community.

And I for one am very irritated by this "true-believer" label that
someone has been spreading to journalists. I hardly think that the
law of energy conservation is particularly superstitious or irrational,
and that, rather than models or historical data or superstition is the real
basis of the concern. The exact sensitivity of global mean surface temperature
to greenhouse gas perturbations is a scientific issue of considerable
practical importance. The tendency of the press to garble it into a question
of "belief" or "non-belief" as if it were a question of faith with only
two conceivable answers is both ignorant and insulting. (imho of course)

Can someone, maybe at Arizona, dig up a reference or a name or
an email address for these Tree Rings Research folks? Respond by email,
please to above (new) address or [e-mail] .
