Phil, I fully agree. The point is not to blame anyone at all - at least
my point was to track down the source in order to be able to show the
skeptics (or in my special case, the school authorities) that this old
graph is completely superseded and should not be used any more in teaching!
And I also see your problem: what we are finding out now makes the IPCC
process look somewhat unsophisticated back in 1990, so it is a
diplomatic conundrum how to be completely truthful in reporting this, as
we need to be as scientists, without providing the skeptics undue fodder
for attacking IPCC. But maybe we're too concerned - the skeptics can't
really attack IPCC easily in this case without shooting themselves in
the foot.

Cheers, Stefan
