Ozone And Climate Change

The mountain of information coming out of the respective regimes on climate change, ozone depletion and air pollution is monumental

Humankind has dramatically altered the composition of the atmosphere during the past 150 years, chiefly by increasing the concentrations of naturally occurring greenhouse gases such as carbon dioxide and, in the last half century, by introducing new ones. Excessive amounts of greenhouse gases trap heat, which the earth would normally radiate back to space, thereby affecting the energy-storage capacity of the atmosphere and oceans. In recent decades the ozone layer has been severely damaged by man-made chemicals called chlorofluorocarbons (CFCs). Though their use is now prohibited, they will remain in the atmosphere for many decades and, with their effects exacerbated by global warming, will continue to destroy ozone for many years to come. The greatest concern for our well-being during the next millennium is that a modified climate now seems inevitable. How much can we afford to let it change? This highly accessible book introduces and explains the processes causing these interrelated environmental crises, examines the measures currently being formulated to tackle them, and considers how effective such measures are likely to be.

In recent years, several new concepts have emerged in the field of stratospheric ozone depletion, creating a need for a concise in-depth publication covering the ozone-climate issue. This monograph fills that void in the literature and gives detailed treatment of recent advances in the field of stratospheric ozone depletion. It puts particular emphasis on the coupling between changes in the ozone layer and atmospheric change caused by a changing climate. The book, written by leading experts in the field, brings the reader the most recent research in this area and fills the gap between advanced textbooks and assessments.

ALEXANDER GILLESPIE & WILLIAM C.G. BURNS The idea for this book grew out of the Ecopolitics conference in Canberra, Australia in 1996. The conference captured the ferment of the climate change debate in the South Pacific, as well as some its potential implications for the region’s inhabitants and e- systems. At that conference, one of the editors (Gillespie) delivered a paper on climate change issues in the region, as did Ros Taplin and Mark Diesendorf, who are also c- tributors to this volume. This book focuses on climate change issues in Australia, New Zealand, and the small island nations in the Pacific as the world struggles to cope with possible the impacts of environmental change and to formulate effective responses. While Australia and New Zealand’s per capita emissions of greenhouse gases are among the highest in the world, their aggregate contributions are small. However, both nations may exert a disprop- tionate influence in the global greenhouse debate because their obstinate positions at recent conferences of the parties to the United Nations Framework Convention on C- mate Change (FCCC) may provide justification for other developed nations, as well as developing countries, to refuse to make meaningful reductions in their greenhouse gas emissions.

A balanced assessment based on currently available scientific knowledge of the effects that climate change may have on the environment in Europe and the health of its populations. Written in non-technical language the book responds to growing public and political concern about the consequences of such widely publicized phenomena as global warming and stratospheric ozone depletion. The book also responds to evidence that recent warming trends in Europe have already affected health. The book opens with a brief explanation of the causes of climate change and stratospheric ozone depletion followed by an overview of recent European and global initiatives aimed at monitoring trends and assessing their impact on health. The first main chapter on climate change in Europe summarizes currently documented trends and provides a scenario of possible changes throughout the rest of this century. The second and most extensive chapter reviews scientific evidence on specific health consequences. These include effects related to increased episodes of thermal stress and air pollution; changes in foodborne water-related vector-borne and rodent-borne diseases; mortality from floods and other weather extremes; and changes in the production of aeroallergens associated with respiratory disorders including asthma. Chapter three considers health effects linked to stratospheric ozone depletion giving particular attention to adverse effects on the eye and immune system and skin cancer. The remaining chapters discuss health effects expected in the next decade and outline actions urgently needed in the areas of policy monitoring and surveillance and research.

Ozone depletion in the stratosphere and increases in greenhouse gases in the troposphere are both subjects of growing concernâ€"even alarmâ€"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?
