IPCC AR6

At its 41^st Session (Nairobi, Kenya, 24-27 February 2015) the Panel agreed to continue to prepare comprehensive assessment reports and to maintain the existing Working Group structure under which:

• Working Group I assesses the scientific aspects of the climate system and climate change;
• Working Group II assesses the scientific, technical, environmental, economic and social aspects of the vulnerability (sensitivity and adaptability) to climate change of, and the negative and positive consequences (impacts) for ecological systems, socio-economic sectors and human health, with an emphasis on regional sectoral and cross-sectoral issues; consistent with recent considerations it will also focus on the adaptation needs, options, opportunities, and constraints to reduce current and future risks;
• Working Group III assesses the scientific, technical, environmental, economic and social aspects of the mitigation of climate change.

The outlines of the Working Group contributions to the AR6 were developed after a comprehensive scoping process involving the scientific community and governments (Addis Ababa, Ethiopia, 1 – 5 May 2017) and were approved in Plenary at the 46^th Session of the IPCC (Montreal, Canada 6 – 10 September 2017). They can be accessed on the IPCC Website on the following link: http://bit.ly/2wg2QtT.

The contribution of Working Group I will be completed in April 2021, Working Group II in October 2021, Working Group III in July 2021 and the Synthesis Report in September 2022. The outline of the Synthesis Report will be developed in April 2019.

The Coordinating Lead Authors and Lead Authors are responsible for drafting the chapters and revising them taking into account comments submitted by reviewers during the two IPCC-mandated reviews, namely the expert review and the second review by governments and experts. A representative cross-section of authors will also contribute to drafting, revising and finalizing the Technical Summary and Summary for Policymakers (SPM).

A detailed description of the IPCC writing and review process is contained in the “Procedures for the Preparation, Review, Acceptance, Adoption, Approval and Publication of IPCC Reports” which can be viewed on the IPCC website at: https://www.ipcc.ch/pdf/ipcc-principles/ipcc-principles-appendix-a-final.pdf.
