This is relevant to quantifying the UEA contribution to IPCC.
NCAR contributed a lot to the AR4, but very little to IPCC90.
In the back they list people by country and with organization
identified. Only 4 NCARs -- Firor, Dickinson, Schneider, Trenberth.

But it is important to weight contributions. Clearly, contributing author
is much less than (e.g.) lead author.

Wonderful. I have done no more than think of how many points
to give for the various contributions. My spread is less ...

Contributing: 1
Lead: 4
Convening: 10
Editor: 10
Chair: 25

Note that there are other IPCC reports than just the big WG reports.
One would need to use a diff. point system for these. For example, in
Harvey et al., 1997, the editors did nothing.

I didn't try to figure out my contribution -- I just guessed it at about
1/2000. If Ben told you Mike Wehner's remark, this would allow
me to have a parking spot at Berkeley, but only if I rode a unicycle.

I'll be at PCMDI on Dec. 6. Ben thought we might have a Nobel
(or no bull) celebratory dinner on the 5th.
