October 2009 - Chapter Scoping and Outline Approval
The outlines of the Working Group contributions to the IPCC Fifth Assessment Report (AR5) have been finalized. According to the revised timetable agreed by the IPCC at its 31st Session in Bali, Indonesia, in October 2009, the target date for release of the Working Group I contribution to the AR5 on Climate Change 2013: The Physical Science Basis is now September 2013.
As has been the case in the past, the outline of the AR5 has been developed through a scoping process involving climate change experts from all relevant disciplines and users of IPCC reports, including representatives from governments. The scoping meeting to define the outline of the AR5 was held in Venice, Italy, 13-17 July 2009. The outline of the Working Group I contribution to AR5 was approved at the 11th Session of Working Group I and accepted by the 31st Session of the IPCC meeting in Bali, Indonesia, 26-29 October 2009. The complete WGI AR5 Chapter Outline including additional information on Annex I: Atlas of Global and Regional Climate Projections is available in pdf and html format.
