The Intergovernmental Panel on Climate Change (IPCC) is inviting governments to comment on the Final Draft of the Summary for Policymakers (SPM) of the Special Report on “Global Warming of 1.5ºC” (or SR15) ahead of the approval plenary for the SPM at the IPCC’s 48th session in early October, 2018.
The IPCC distributed the Final Draft of the report, whose full name is “Global Warming of 1.5°C, an IPCC special report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty”, to governments on Monday, June 4, 2018 with a request to comment on SPM by July 29.
The review of the Final Draft is a key stage in the preparation of the report, allowing authors to prepare for the line-by-line approval session of the SPM that will take place in Incheon, Republic of Korea, from October 1 to 5,, 2018. The report, to be released on October 8 subject to approval by the Panel, will be the key scientific input into the Talanoa Dialogue at the UN Climate Change Conference to be held in Katowice, Poland, in December.
The aim of this final review, according to the IPCC, is to ensure that the Summary for Policymakers is accurate, well-balanced, presents the findings of the underlying report clearly, and is consistent with the scope of the full report as approved by the Panel at the 44thsession of the IPCC in October 2016.
“This is the last step of the IPCC review process. Chapter drafts have been finalized, and key findings have been distilled into the Summary for Policymakers,” said Valérie Masson-Delmotte, Co-Chair of IPCC Working Group I. “Governments will now review the report that we have prepared following their invitation to the IPCC in December 2015, at COP21.”
In line with IPCC procedures, the report has already undergone two formal review stages: the expert review of the First Order Draft from July 31 to September 24, 2017, and the government and expert review of the Second Order Draft from January 8 to February 25, 2018.
