Assessment Cycles
The work of the IPCC is organized by assessment cycles, a period of time during which several reports are integrated into a final report, called the Synthesis Report (SYR).
Synthesis Reports
Assessment Reports
Working Group Reports
Working Group I evaluates the physical science basis of climate change.
Working Group II evaluates the impacts, adaptation, and vulnerability.
Working Group III evaluates the mitigation.
Special Reports
Sixth Assessment cycle
The Intergovernmental Panel on Climate Change (IPCC) is finalizing its Sixth Assessment cycle, during which the IPCC has produced 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) is the last of the Sixth Assessment Report products, finalized in March 2023.
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.
