IPCC Working Group I Sixth Assessment Report Authors' Survey

The IPCC’s Sixth Assessment Cycle (AR6) ran from October 2015 to July 2023 and comprised seven individual reports (the busiest IPCC cycle to date). The Working Group I (WGI) contribution to the IPCC AR6 was approved and accepted in August 2021. 234 authors from 64 countries led the assessment of the understanding of the current state of the climate, including how it is changing, the role of human influence, the state of knowledge about possible climate futures, climate information relevant to regions and sectors, and limiting human-induced climate change. This report draws on responses from a feedback survey of over 150 Authors and Review Editors on the successes, challenges and lessons-learned from the WGI AR6 experience. The survey was developed by the WGI Bureau and TSU and sent to all WGI authors and Review Editors. It focused on both the WGI AR6 process and the resulting products.
