Summary

The SYR is a self-contained synthesis of the most policy-relevant material drawn from the scientific, technical, and socio-economic literature assessed during the Sixth Assessment. This report integrates the main findings of the AR6 Working Group reports and the three AR6 Special Reports. It recognizes the interdependence of climate, ecosystems and biodiversity, and human societies; the value of diverse forms of knowledge; and the close linkages between climate adaptation, mitigation, ecosystem health, human well-being, and sustainable development. Building on multiple analytical frameworks, including those from the physical and social sciences, this report identifies opportunities for transformative action which are effective, feasible, just and equitable systems transitions, and climate resilient development pathways. Different regional classification schemes are used for physical, social and economic aspects, reflecting the underlying literature.
