IPCC Principles Appendix A

First Review (by Experts)

First order draft Reports should be circulated by Working Group/Task Force Bureau Co-Chairs for review. The Working Group/Task Force Bureaux shall seek the participation of reviewers encompassing the range of scientific, technical and socio-economic views, expertise, and geographical representation and shall actively undertake to promote and invite as wide a group of experts as possible. This includes experts nominated as Coordinating Lead Authors, Lead Authors, Review Editors or Contributing Authors as included in lists maintained by the IPCC. Government Focal Points should be notified of the commencement of this process.
The first draft Reports should be sent to Government Focal Points, for information, along with a list of those to whom the Report has been sent for review in that country. The Working Group/Task Force Bureau Co-Chairs should make available to reviewers on request during the review process specific material referenced in the document being reviewed, which is not available in the international published literature.
Expert reviewers should provide the comments to the appropriate Lead Authors through the relevant Working Group/Task Force Bureau Co-Chairs with a copy, if required, to their Government Focal Point.
Coordinating Lead Authors, in consultation with the Review Editors and in coordination with the respective Working Group/Task Force Bureau Co-Chairs and the IPCC Secretariat, are encouraged to supplement the draft revision process by organising a wider meeting with principal Contributing Authors and expert reviewers, if time and funding permit, in order to pay special attention to particular points of assessment or areas of major differences.

Review Process

The IPCC Procedures require that the review be carried out by experts. This is not a public review and prospective Expert Reviewers are requested to provide information on their relevant scientific and technical expertise when they register. The IPCC Procedures state that the review shall be undertaken by experts nominated by governments and participating organizations. In addition, the Working Group Bureaus shall seek the participation of the range of scientific, technical and socio-economic views, expertise, and geographical representation.
The IPCC Secretariat will notify member governments and observer organisations of the call for registration and start of the review, inviting them to solicit the participation of their experts. All those previously nominated for a role in the SR15 but not selected will be invited to participate. Those individuals who have contacted the WGI TSU about the possibility of being an Expert Reviewer will also be contacted. There will be an announcement on the IPCC website and on social media that the review registration site is open. All experts who submitted comments on the FOD will be invited to review the SOD and to submit further comments.
