Through that agreement and its subsequent amendments and adjustments, many nations of the world have carried out policies to reduce and then phase out their use of ozone-depleting chemicals. The Montreal Protocol also called for the international scientific community to periodically update governments on the latest scientific findings related to the ozone layer. Conducted under the auspices of the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) and co-sponsored by NASA, NOAA, and the European Commission, these periodic "state-of-the-science" assessments have guided policymakers as they strengthened the original provisions of the Montreal Protocol. Together with colleagues at NASA, other NOAA laboratories, and other scientific institutions across the U.S. and around the world, CSD (formerly the Aeronomy Laboratory) has played a leading role in preparing these assessments"--Publisher's website.Includes bibliographical references.Atmospheric ozoneOzone layerOzone layer depletionAtmospheric chemistryGlobal warmingAtmospheric chemistryfastAtmospheric ozonefastGlobal warmingfastOzone layerfastOzone layer depletionfastAtmospheric ozone.Ozone layer.Ozone layer depletion.Atmospheric chemistry.Global warming.Atmospheric chemistry.Atmospheric ozone.Global warming.Ozone layer.Ozone layer depletion.United States.National Aeronautics and Space Administration,Great Britain.Department of the Environment,United States.National Oceanic and Atmospheric Administration,United Nations Environment Programme,World Meteorological Organization,VVCVVCVVCOCLCFOCLCQGPOJOURNAL9910709753403321Scientific assessment of stratospheric ozone3315919UNINA
