            This Synthesis Report (SYR) of the IPCC Sixth Assessment Report (AR6)
            summarises the state of knowledge of climate change, its widespread
            impacts and risks, and climate change mitigation and adaptation, based
            on the peer-reviewed scientific, technical and socio-economic literature
            since the publication of the IPCC’s Fifth Assessment Report (AR5) in
            2014.
            The assessment is undertaken within the context of the evolving
            international landscape, in particular, developments in the UN
            Framework Convention on Climate Change (UNFCCC) process,
            including the outcomes of the Kyoto Protocol and the adoption of the
            Paris Agreement. It reflects the increasing diversity of those involved in
            climate action.
            This report integrates the main findings of the AR6 Working Group
            reports58 and the three AR6 Special Reports 59
            . 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 change 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 using concepts
            of systems transitions and resilient development pathways 60
            . Different
            regional classification schemes 61 are used for physical, social and
            economic aspects, reflecting the underlying literature.
            After this introduction, Section 2, ‘Current Status and Trends’, opens
            with the assessment of observational evidence for our changing
            climate, historical and current drivers of human-induced climate
            change, and its impacts. It assesses the current implementation of
            adaptation and mitigation response options. Section 3, ‘Long-Term
            Climate and Development Futures’, provides a long-term assessment of
            climate change to 2100 and beyond in a broad range of socio-economic
            futures. It considers long-term characteristics, impacts, risks and costs
            in adaptation and mitigation pathways in the context of sustainable
            development. Section 4, ‘Near- Term Responses in a Changing Climate’,
            assesses opportunities for scaling up effective action in the period up
            to 2040, in the context of climate pledges, and commitments, and the
            pursuit of sustainable development.
            Based on scientific understanding, key findings can be formulated as
            statements of fact or associated with an assessed level of confidence
            using the IPCC calibrated language62
            . The scientific findings are
            drawn from the underlying reports and arise from their Summary for
            Policymakers (hereafter SPM), Technical Summary (hereafter TS), and
            underlying chapters and are indicated by {} brackets. Figure 1.1 shows
            the Synthesis Report Figures Key, a guide to visual icons that are used
