Ozone Depletion, Greenhouse Gases, and Climate Change. Proceedings of a Joint Symposium by the Board on Atmospheric Sciences and Climate and the Committee on Global Change, National Research Council (Washington, D.C., March 23, 1988).

The motivation for the organization of this symposium was the accumulation of evidence from many sources, both short- and long-term, that the global climate is in a state of change. Data which defy integrated explanation including temperature, ozone, methane, precipitation and other climate-related trends have presented troubling problems for atmospheric science since the 1980's. Ten papers from this symposium are presented here: (1) "Global Change and the Changing Atmosphere" (William C. Clark); (2) "Stratospheric Ozone Depletion: Global Processes" (Daniel L. Albritton); (3) "Stratospheric Ozone Depletion: Antarctic Processes" (Robert T. Watson); (4) "The Role of Halocarbons in Stratospheric Ozone Depletion" (F. Sherwood Rowland); (5) "Heterogenous Chemical Processes in Ozone Depletion" (Mario J. Molina); (6) "Free Radicals in the Earth's Atmosphere: Measurement and Interpretation" (James G. Anderson); (7) "Theoretical Projections of Stratospheric Change Due to Increasing Greenhouse Gases and Changing Ozone Concentrations" (Jerry D. Mahlman); (8) "Historical Trends in Atmospheric Methane Concentration and the Temperature Sensitivity of Methane Outgassing from Boreal and Polar Regions" (Robert C. Harriss); (9) "Global Temperature Trends" (Kevin E. Trenberth); and (10) "Use of Numerical Models to Project Greenhouse Gas-Induced Warming in Polar Regions (The Conceptual Basis Developed Over the Last Twenty Years)" (Robert E. Dickinson). A glossary of terms, agendas, and a list of participants are appended. (CW)
