The IPCC was jointly established in 1988 by the World Meteorological Organization and the United Nations Environment Programme to provide comprehensive assessments of the scientific basis of climate change. It has produced five assessment reports to date (1990, 1995, 2001, 2007, 2013-2014) as well as numerous special reports. The IPCC's role is to objectively evaluate scientific information on climate change and its impacts in order to inform policymakers. Its reports have informed major international agreements on climate change mitigation including the UNFCCC and Paris Agreement. The IPCC is currently working on its sixth assessment cycle to be completed in 2021-2022.
