IPCC experts, govts review of special report on global warming of 1.5ºC holds early January

The expert and government review of the second order draft of the Intergovernmental Panel on Climate Change (IPCC) Special Report on Global Warming of 1.5ºC will take place from 8 January until 25 February 2018. Expert Reviewers registration opened on 15 December 2017, until one week before the end of the review period.
The government and expert review of the draft report is a key element of the IPCC assessment process. Experts and government representatives from around the world will offer comments and suggestions to the author teams working on the report 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.
“The review process is essential for the quality of IPCC assessment reports. The first round of review was extremely successful, with nearly 13,000 comments from almost 500 expert reviewers in over 60 countries,” said Valérie Masson-Delmotte, Co-Chair of IPCC Working Group I. “The authors have carefully considered these comments, as well as any new scientific literature, and prepared a second draft. Registering as a reviewer is an opportunity for experts, including early career scientists, to join this collective effort and help to strengthen the assessment even further.”
All IPCC reports go through multiple stages of formal review. After the expert review of the first draft, the second draft is reviewed by both governments and experts alongside a first draft of the Summary for Policymakers (SPM). Once the second round of review comments have been taken into account, governments review the final draft of the report and offer written comments on the SPM. Finally, governments meet to approve the SPM line by line and accept the underlying report.
This thorough review process ensures that IPCC reports consider objectively the full range of scientific, technical and socio-economic information from around the world. Expert Reviewers can register here with a self-declaration of expertise. Those who reviewed the First Order Draft review will automatically be registered for the second round. Review contributions will be acknowledged in the final report, due to be published in October 2018.
