From: "Rasmus Benestad" To: Subject: Re: Figure 7.1c from the 1990 IPCC Report Date: Sat, 6 Jan 2007 17:58:46 -0000 (GMT) Reply-to: rasmus.benestad@met.no Cc: , , , , , , , , , , , , , , , , , , , 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. Rasmus > Phil, I fully agree.
