The document provides an overview of the Intergovernmental Panel on Climate Change (IPCC). It summarizes that the IPCC was established in 1988 by the World Meteorological Organization and United Nations Environment Programme to assess scientific information on climate change. It produces major assessment reports and special reports to inform policymakers about climate change. Key points include that IPCC reports involve authors and reviewers from around the world and aim to be policy-relevant but not policy-prescriptive. Major reports have helped inform international agreements like the UNFCCC and Paris Agreement. The current assessment cycle is producing several special reports to feed into the 2023 global stocktake.
