The Ocean and Cryosphere in a Changing Climate

Report

For the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC), more than 100 scientists from more than 30 countries are assessing the latest scientific knowledge about the physical science basis and impacts of climate change on ocean, coastal, polar and mountain ecosystems, and the human communities that depend on them. Their vulnerabilities as well as adaptation capacities are also evaluated. Options for achieving climate-resilient development pathways will be presented.

SROCC is prepared under the joint scientific leadership of Working Group I and Working Group II, with operational support from the Working Group II Technical Support Unit.

The IPCC will consider the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) on 20-23 September 2019 during its 51st Session to be held in the Principality of Monaco. The report is due to be launched on 25 September 2019.

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.

History

The Scientific Steering Committee for the scoping of a 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. A total number of 44 pre-scoping questionnaire responses were submitted. About 100 experts from 40 countries met on 6 – 9 December 2016 in Monaco and prepared a draft outline. More information is available in the report of the scoping meeting.

At its 43rd Session (Nairobi, Kenya, 11 – 13 April 2016), the IPCC Panel decided to prepare a special report on climate change and the oceans and the cryosphere.

During its 45th Session (Guadalajara, Mexico, 28 – 31 March 2017), the IPCC Panel approved the outline of the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC).

The Intergovernmental Panel on Climate Change (IPCC) will consider the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) on 20-23 September 2019 during its 51st Session to be held in the Principality of Monaco. The report is due to be launched on 25 September 2019.
