This book underscores the re-emergence of the ozone hole problem and deals with it in its current context. It traces the history of the ozone hole from the stage of formation of the stratospheric ozone 'layer', millions of years ago, into the late 20th century when the anthropogenic destruction of that ozone was discovered. The chapters are written to bring the the reader up to the present day. Factors that influence stratospheric ozone are discussed and the ways to halt ozone depletion are cataloged. Over the last two decades there has been an increasing amount of focus placed on global warming. More and more complex interrelationships are being discovered between ozone depletion and two other global concerns: climate change and ocean acidification. This book is of interest to students and researchers looking for a current overview of ozone.
