The Intergovernmental Panel on Climate Change (IPCC) has opened the first order draft  of the Working Group I contribution to the Sixth Assessment Report (AR6) for expert review, marking an important step in the preparation of the flagship report.

The review runs from 29 April to 23 June 2019, and interested experts can register until midnight CET on 16 June 2019 on the IPCC website. 

IPCC reports go through repeated drafts and reviews to help ensure that the report provides a balanced and comprehensive assessment of the latest scientific findings.

The Working Group I contribution to AR6, Climate Change 2021: The Physical Science Basis, will assess large-scale climate changes, climate processes and feedback, and regional climate information.

During the review, experts may comment on the structure and comprehensiveness of the report and suggest improvements on the presentation of materials, graphically or through tables. They may also propose revisions, relevant additional papers with full citations, and ways to shorten the text without losing relevant information.

IPCC reports undergo multiple stages of review, first by experts and then by both governments and experts.  Experts who comment on this draft will also be invited to comment on the second order draft. All expert reviewers will be acknowledged in the published report, due to be finalized in 2021.

More information on the role of an expert reviewer is available in Annex 1 of Appendix A to the Principles Governing IPCC Work.

Additional information explaining the Expert Review process is available here.
