I remember that Figure. When it appeared I thought "what crap". I thought Chris had made it up from mainly Lamb material. We knew well then that Lamb's stuff was garbage -- and, of course, Chris was ignorant of paleo data. The blind being led by the blind -- and now it has come back to haunt us. Poetic justice.
You might recall that I used a very different Figure from Rothlisberger in the Wigley and Kelly paper. This was a good choice in retrospect because it looks much more like Mann et al.
I hate to say this (actually not) but I think I got it right and IPCC got it wrong -- not the first time.
