The Synthesis Report of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) addresses climate change impacts, risks and solutions, while assessing the likelihood of projections and proposing strategies for transformation.
This Synthesis Report is the main publication of the 6th Assessment cycle of the IPCC, which started in 2016. It draws on the reports of the three Working Groups of the IPCC : Physical Science Basis of Climate Change (WGI, August 2021), Climate Change Impacts, Adaptation and Vulnerability (WGII, Feb. 2022) and Mitigation of Climate Change (WGIII, April 2022), as well as on the three Special Reports on Global Warming of 1.5°C (2018), on Climate Change and Land (2019), and on the Ocean and the Cryosphere in a Changing Climate (2019).
🔎 Key takeaways
The Synthesis Report (SYR) of the IPCC Sixth Assessment Report (AR6) is divided into three sections:
Section A covers the current status and trends of climate change. Despite policy efforts to mitigate GHG, current actions are insufficient to meet climate goals.
Section B provides a long-term assessment of climate change to 2100 and beyond. Continued greenhouse gas emissions intensify risks and hazards, but rapid reductions can slow atmospheric changes. As temperatures increase, adaptation options weaken. Net zero CO2 emissions are needed to limit warming.
Section C assesses opportunities for scaling up effective action which should apply immediate long-term measures for mitigation. Equity, social justice, and just transition processes can facilitate climate action.
💡 The Report summarizes the latest scientific literature on climate change since 2014.
Using a multiple analytical frameworks which highlights the interaction of the challenges, it recognizes the interdependence of climate, ecosystems, biodiversity, and human societies.
Published in March 2023, it also informs the 2023 Global Stocktake of the Paris Agreement organized during COP28
