Basic Information on Stratospheric Ozone Depletion

A good place to start for information about ozone layer depletion is the 2010 Scientific Assessment of Ozone Depletion Exit EPA Disclaimer, the product of 312 scientists from 39 countries, which summarizes the current understanding of the stratospheric ozone layer and its relation to humankind and the earth.  Also available is the recent report, Environmental Effects of Ozone Depletion and its Interactions with Climate Change: 2010 Assessment (PDF, 328 pp, 10 MB) Exit EPA Disclaimer. Related to this report is the document, Questions and Answers about the Environmental Effects of the Ozone Layer Depletion and Climate Change: 2010 Update (PDF, 50 pp, 2.5 MB) Exit EPA Disclaimer.  The previous 2006 Assessment includes 20 Questions and Answers about the Ozone Layer (PDF) (50 pp, 1.66MB, About PDF) Exit EPA Disclaimer, which was prepared for students and the general public.This page also provides other sources of general information about the ozone layer and the how human activities can lead to its destruction:
