Actually Nick the question posed in my previous reply is rather easy to answer.............
The IPCC is currently starting to outline its Fifth Assessment Report (AR5) which will be finalized in 2014. As it has been the case in the past, the outline of the AR5 will be developed through a scoping process which involves climate change experts from all relevant disciplines and users of IPCC reports, in particular representatives from governments. As a first step, experts, governments and organizations involved in the Fourth Assessment Report have been asked to submit comments and observations in writing. These submissions are currently being analysed by members of the Bureau. The scoping meeting to define the outline of the AR5 is scheduled in Venice, Italy, for 13-17 July 2009 (
attendance is by invitation only). The outline will be submitted to the 31st Session of the IPCC and Sessions of the three Working Groups, which will be held in Bali, Indonesia, 26-29 October 2009.
You can rest assured that there won't be even the slightest hint of a contrary opinion heard at that gathering

Main text presently appears on IPCC website.
