This collection consists of the personal papers of UCAR/NCAR scientists who served as Lead Authors, Co-Authors, and Contributing Authors to the Climate Change 2007 - The Physical Science Basis, the contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). Materials include articles, calendars, chapter drafts, correspondence, powerpoint presentations, notes, and photographs. This is not an official archive of the IPCC; rather it is a collection of items voluntarily donated to the NCAR Archives by UCAR/NCAR scientists interested in preserving the historic record of climate science. Access is available in the NCAR Library's digital repository, OpenSky.
