IPCC AR6 WGII extensions

Working Group II of the Intergovernmental Panel on Climate Change (IPCC), which assesses scientific literature relating to impacts, adaptation, and vulnerability, has revised the timeline for preparing its contribution to the Sixth Assessment Report (AR6) because of disruption caused by the COVID-19 pandemic.

Authors of IPCC reports volunteer their time and expertise. A survey by Working Group II found that its authors are experiencing unique and sustained challenges in the wake of COVID-19. Their ability to deliver to the original timeline has been compromised by competing responsibilities, limited resources and diverse personal challenges.

In light of these challenges, Working Group II is extending a number of milestones due to be reached in 2020 by around four months. The cut-off date for scientific literature to be submitted for publication, if it is to be included in the assessment, moves to 1 November 2020. The government and expert review of the report’s Second Order Draft will now take place between 4 December 2020 and 29 January 2021. The Fourth Lead Author Meeting to prepare the final draft will now be held in March 2021.
