The 1987 Montreal Protocol on Substances that Deplete the Ozone Layer called for global action to reduce the use of chlorofluorocarbons (CFCs) and halons. In addition, it requested periodic expert assessments of, among other things, the available scientific information related to the Earth's stratospheric ozone layer. Since 1987, the Parties have used the scientific assessment information as part of the basis for their decisions to amend or adjust the Montreal Protocol to strengthen its protection of the ozone layer. Observations now show that ozone-depleting substances in the lower atmosphere as well as in the stratosphere are decreasing, and the ozone layer is showing some early signs of recovery. A member of the 2006 Assessment Scientific Steering Committee, Dr. Ravishankara will discuss the findings of the current Science assessment, whose preparation involved more than 300 scientists from 34 countries as lead authors, co-authors, contributors, and reviewers.
