IPCC AR6 Early Career Group Review

YESS, APECS, PYRN, MRI, and PAGES ECN are coordinating an IPCC group review by early career experts for the 6th Assessment Report (AR6) by the Intergovernmental Panel on Climate Change’s (IPCC).


Since 2018, more than one hundred international early career scientists have participated of the several reviews we organized. By participating, reviewers not only get recognized as early career experts, but also gain valuable training and insight in the scientific review process for reports written for policy makers.

The YESS Community, along with the Association of Polar Early Career Scientists (APECS), the Mountain Research Initiative (MRI), the Past Global Changes Early-Career Network (PAGES-ECN) and the Permafrost Young Research Network (PYRN) successfully organized the group review of the Second Order Draft (SOD) of Working Group II (WGII) contribution to the Intergovernmental Panel on Climate Change (IPCC) 6th Assessment Report (AR6) by early career scientists.

The IPCC expert review period took place from 4 December 2020 to 29 January 2021.The organizing team of this group review was composed of 50 team members, whose dedication and hard work made this group review possible despite the tight deadlines and the challenges of the pandemic. A total of 186 reviewers, including some of the organizers of the review, provided comments on sections of the report. As a result of this group effort, 2420 comments were submitted to the IPCC.

In total, 39 YESS members participated as reviewers, chairs or lead chairs of this project.
