My updated entry on the IPCC has been published (September 2020) in the International Encyclopedia of Geography (from Wiley)

Abstract: The Intergovernmental Panel on Climate Change (IPCC) was constituted by the United Nations in 1988 to conduct periodic assessments of scientific knowledge pertaining to climate change. To date it has published five full?scale assessment reports, together with a significant number of special reports. These reports are produced by independent experts drawn from around the world, operating under evolving protocols of knowledge assessment established by the Panel’s governing body, which is elected by the world’s national governments. The IPCC assessments are guided by the principle of generating policy?relevant, but not policy?prescriptive, knowledge. In 2007, the IPCC was awarded, jointly, the Nobel Peace Prize, but in 2010 it came under public scrutiny because of errors in its Fourth Assessment Report. A Sixth Assessment Report was scheduled to be published in 2021/2022; however, with the outbreak of COVID?19, this publication date has been placed in doubt.
