Second-Order-Draft (SOD) of the IPCC Special Report on Ocean and Cryosphere in a Changing Climate (SROCC) has been made available for expert review. For the scientific community, this is the last opportunity to provide comments. The deadline for providing comments is January 11, 2019.
Relevant chapters for the cryosphere (glaciers, permafrost, sea-ice, snow) include Chapter 2 (High Mountain Areas), Chapter 3 (Polar regions) and Chapter 4 (Sea-level change). Note that the entire report includes both the physical science as well as the human dimension of the overall topic intertwined in each chapter.
The quality of the final report, to be published in September 2019, depends to a high degree on critical reviews from the community. The author team will have to respond and address every single review comment that is submitted through the IPCC system.
To submit expert review comments on the draft or parts thereof, you have to register online (latest by January 4) https://www.ipcc.ch/apps/comments/srocc/sod/register.php
Any publications to be considered in the final report must have been submitted to a peer-reviewed journal by 15 October 2018 and must be accepted at the latest by 15 May 2019.
