Climate Change 2021: Summary for All

This publication is a plain-language summary of the IPCC Working Group I climate change report released in August 2021. It was written by members of the Working Group I Technical Support Unit (WGI TSU) and several authors of the report. Additionally, many volunteers offered feedback and guidance along the way. It has not undergone the same approval process that official IPCC documents undergo, such as the Summary for Policymakers.
