The United States Global Change Research Program (USGCRP), in cooperation with the Department of State, requests expert review of the second-order draft of the IPCC Special Report on Global Warming of 1.5°C, including the first draft of its Summary for Policymakers (SPM).

  1. As part of the U.S. Government Review, starting on 8 January 2018, experts wishing to contribute to the U.S. Government review are encouraged to register via the USGCRP Review and Comment System ( Instructions and the report itself will be available for download. The USGCRP coordination office will compile U.S. expert comments and submit to the IPCC, on behalf of the Department of State, by the prescribed deadline. To be considered for inclusion in the U.S. Government submission, comments must be received by 8 February 2018.
  2. Experts may choose to provide comments directly through the IPCC’s Expert Review process, which occurs in parallel with the U.S. Government Review. Registration opened on 15 December 2017, and runs through 18 February 2018:
At the 44th Session of the Panel (Bangkok, Thailand; 17-20 October 2016), the IPCC approved the outline(link is external) for the Special Report. A zero-order draft was compiled and reviewed in April 2017, with a first-order draft prepared by the summer. The current draft reflects feedback on that first-order draft, collected during the first Expert Review (31 July – 24 September 2017). Refer to the Principles Governing IPCC Work(link is external) for more information on the rules and procedures governing IPCC assessment development. Review is an essential part of the IPCC process. The purpose of these reviews is to ensure that the report presents a comprehensive, objective, and balanced view of the areas covered.
A dedicated instance of the USGCRP Review and Comment (R&C) System will accept comments from 08 January – 08 February 2018. All comments must be input via the R&C System if they are to inform the U.S. Government position; additional information—including instructions, supplementary materials, and the draft report itself—can be found on the landing page. Reviewers can provide comments via an on-line mechanism or via an off-line spreadsheet for later upload.
Experts are advised that they have the option to submit comments direct to the IPCC rather than participate in this USGCRP-managed review.

The IPCC deadline for submission of Government and Expert Review comments on the second-order draft of the Special Report on Global Warming of 1.5°C is 25 February 2018.
The second-order draft of the Special Report on Global Warming of 1.5°C, which includes the first draft of the SPM, does not represent an approved product of the IPCC, and as such should not be cited, quoted, or distributed other than for the purpose of this review. Based on submitted comments, the draft Special Report will undergo further revision and the SPM another round of review in the summer of 2018, prior to final approval and release during the 48th Session of IPCC in October 2018.
