Synthesis Report of the Sixth Assessment Report
A Report of the Intergovernmental Panel on Climate Change
The Intergovernmental Panel on Climate Change (IPCC) is currently in its Sixth Assessment cycle, during which the IPCC will produce the Assessment reports of its three Working Groups, three Special Reports, a refinement to the Methodology Report and the Synthesis report. The Synthesis Report (SYR) will be the last of the Sixth Assessment Report products, due for release in time to inform the 2023 Global Stocktake by the United Nations Framework Convention on Climate Change as mandated by Decision 1/CP.21 .
2023 is when countries will review progress towards the Paris Agreement goals, including the goal of keeping global warming to well below 2°C while pursuing efforts to limit it to 1.5°C. The Synthesis Report of the Sixth Assessment Report (AR6) provides an overview of the state of knowledge on the science of climate change, emphasizing new results since the Fifth Assessment Report (AR5) in 2014. It is fully based on the reports of the three Working Groups of the IPCC, as well as on the three Special Reports on Global Warming of 1.5°C, on Climate Change and Land, and on the Ocean and the Cryosphere in a Changing Climate. It provides an integrated view of climate change as the final part of the Sixth Assessment Report. The Synthesis Report consists of the Summary for Policymakers and a Longer Report. It will be published as a stand-alone publication in the six official UN languages.
