Summary for Policymakers (approved) and Final Draft (accepted)

The Summary for Policymakers of the Working Group I contribution to the IPCC Fifth Assessment Report Climate Change 2013: The Physical Science Basis was approved and accepted by the IPCC Panel on 27 September 2013. The version that was released on that date was subject to copy edit and final layout. In this version of the Summary for Policymakers, errors were discovered by the authors of the report after its approval and acceptance by the IPCC. The errata to the 27 September version of the Summary for Policymakers were approved by the IPCC Executive Committee as delegated by the Panel and can be found in the table below.

The Final Draft Report, dated 7 June 2013, of the Working Group I contribution to the IPCC Fifth Assessment Report Climate Change 2013: The Physical Science Basis was accepted but not approved in detail by the Twelfth Session of Working Group I and the Thirty-Sixth Session of the IPCC on 27 September 2013 in Stockholm, Sweden. It consists of the full scientific and technical assessment undertaken by Working Group I.

The Final Draft Report has to be read in conjunction with the document entitled “Climate Change 2013: The Physical Science Basis. Working Group I Contribution to the IPCC 5th Assessment Report - Changes to the Underlying Scientific/Technical Assessment” to ensure consistency with the approved Summary for Policymakers (IPCC-XXXVI/Doc.4) and presented to the Panel at its Thirty-Sixth Session. This document lists the changes necessary to ensure consistency between the full Report and the Summary for Policymakers, which was approved line-by-line by Working Group I and accepted by the Panel at the above-mentioned Sessions. Before publication the Final Draft underwent copyediting and error correction as necessary, consistent with the IPCC Protocol for Addressing Possible Errors. In addition to the individual drafts, a listing of the substantive edits made to the report prior to publication, including corrections of errors and changes made to ensure full consistency between the SPM and the underlying report is provided.
