Authors and Review Editors

A call for nomination of authors was sent to governments, Observer Organizations and IPCC Bureau Members on 5 April 2017. They were asked to submit their nominations via their Focal Points by Wednesday, 17 May 2017 (midnight CEST) using the online portal for submitting nominations.

The IPCC selected the author teams that are now preparing the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). The selected experts took on roles of Coordinating Lead Authors and Lead Authors – who draft each individual chapter – and Review Editors, who ensure that comments by experts and governments are given appropriate consideration as the report develops. The teams are working together to produce the Special Report, set to be finalized in September 2019.

The full list of SROCC Coordinating Lead Authors, Lead Authors and Review Editors is available on the author database.

Statistics about author nominations can be accessed on the public portal.

Scoping

About 100 experts from 40 countries met on 6 – 9 December 2016 in Monaco and prepared a draft outline of the Special Report on climate change and the oceans and the cryosphere. The draft was considered by the Panel during its 45th Session at the end of March 2017. All the details of the scoping meeting are available in the scoping meeting report.

Pre-Scoping

The Scientific Steering Committee for the scoping of the Special Report on climate change and the oceans and the cryosphere circulated a questionnaire to IPCC Focal Points and Observer Organizations on 7 October 2016 with a closing date for responses of 7 November 2016. A total number of 44 pre-scoping questionnaire responses were submitted, with 28 submissions from developed countries and 16 from developing countries or economies on transition. More information on the results of the questionaire is available in the report of the scoping meeting here.
