Fifth Assessment Report (AR5)

The outlines of the Working Group contributions to the IPCC Fifth Assessment Report (AR5) have been finalized. According to the timetable agreed by the IPCC at its 32st Session in Busan, Republic of Korea, in October 2009, the Working Group III contribution to the AR5, Climate Change 2014: Mitigation of Climate Change, will be released in April 2014.

One scoping meeting to outline the AR5 was held 13-17 July 2009 in Venice, Italy. Invited experts from governments and academia discussed and developed the scope and table of contents for the three Working Groups contributions to the AR5. They also identified major issues of integration and synthesis.

During its 9th Session (26-27 October 2009), the IPCC WGIII finalized and approved the chapter outlines of the WGIII contribution to the AR5. The WGIII outline (pdf), as well as those for Working Groups I and II, was then accepted by the 31st Session of the IPCC on 29 October 2009 in Bali, Indonesia.

Starting in January 2010, governments and participating organizations have been asked to nominate experts to act as authors and reviewers for the three Working Group contributions to the AR5. Authors have been selected by the IPCC Working Group Bureaus, as stipulated in the IPCC procedures and have been noted by the Bureau at its 41st session in 19-20 May 2010 in Geneva. The writing process has started in the second half of 2010 for Working Group I and will start in early 2011 for Working Groups II and III.

In addition to meetings of Lead Authors for the AR5, a number of expert meetings and workshops will be held to broaden the basis for the assessment, for instance to address issues where limited peer reviewed literature exists, as well as to address cross-cutting matters.
