Ozone depletion in the stratosphere and increases in greenhouse gases in the troposphere are both subjects of growing concern—even alarm—among scientists, policymakers, and the public. At the same time, recent data show that these atmospheric developments are interconnected and in turn profoundly affect climatic conditions. This volume presents the most up-to-date data and theories available on ozone depletion, greenhouse gases, and climatic change. These questions and more are addressed: What is the current understanding of the processes that destroy ozone in the atmosphere? What role do greenhouse gases play in ozone depletion?
