I think that this story could possible catch on and make headlines, so I
agree that we should be careful. But it's important that we bring the
*true* picture out, and it is best that this is done by RealClimate rather
than a sceptic site. The general scientific side of the IPCC report (i.e.
all the peer-reviewed papers ad the scientific theories) is still sound,
but to explain how *one* figure was shoe-horned into the report is harder
to defend. The sceptics may argue that the IPCC reports are political
after all, and this is also what it sounds like if governments 'hoisted
the national flag' by having it's own figures inserted last minute.
However, by providing an account of the 'evolution of the IPCC report
writing', we could possibly give the story a softer landing. E.g. how many
times of review the first report underwent as compared to the present
report. We should also put this in perspective - the report is large and
covers a wide range of topics, and most (all but our case?) is true to the
science. There are sometimes a few rotten apples in a good batch,
unfortunately. But the important part is that we don't accept rotten
apples and that we sort it out! Forthcoming and up-front. Another
important side is that this can provide a lesson for the scientific
communities.
