do you have the titles of papers in cl28 or can I find them on a web site?

Ray,
Modified my little bit on this diagram - so thanks. It is worth
looking at the 1996 IPCC Report. There is reference to B+J(1993)
and the 1992 book and its second edition - as well as a number
of papers from the Il Ciocco book. This was all written by
Neville Nicholls, although I recall sending him some
text. What this 2cnd report says is much better, even
reading 10 years later, than what was in the 1990 one.
I reckon IPCC (not sure who I really mean here) assumed
that this superceded the 1990 report.
Cheers
Phil

Hi Phil:
I've made some edits and comments on the attached. More generally, I think you need to
comment on the x & y axis scales as used by later authors. For example, in the figure
used originally, it went through ~1950; the figure Stefan circulated used by German
schools changes the same scale to 2000, thereby deliberately ignoring the recent
warming. They also change the y-axis scale, I think. And nobody ever said if the
original units were in F or C!
I spoke to Jack Eddy, by the way. He has lung cancer but seems to be doing OK with
chemotherapy, and he sounded pretty chipper. He said he did not recall where he got his
Earth Quest figure, but it may have been from Tom Webb (see Global Changes of the Past,
p. 61 on) or from Lamb.
There is another side to this which you don't mention --the first attempt to expand by
factors of 10, different so-called "global temperatures" was in the 1975 GARP report,
Understanding Climatic Change. In that, for the last 1000 years they used Lamb's
eastern European winter severity index. This version then got reproduced and further
mangled in several later publications, as shown in Tom's chapter. I am as guilty as the
rest--I made up something from a corner of my brain on p.33 of my paleoclimatology
book! But I did say schematic...!
I'm not sure why people think this is such a sensitive topic (vis a vis the IPCC).
Apart from the fact that they had Chris Dork Folland writing the paleo section, the
first IPCC was a good starting point, and we've clearly come a long way since then.
Just because people refer back to that for their own purposes (ie Wegman) does not
reflect on the IPCC process as it has evolved.
Any day in Vienna is OK for me. I'll be there (with Jane) from Monday-Thursday (leaving
Friday am).
Look forward to getting together there....
