This book is the first comprehensive history of international efforts to protect the ozone layer, the greatest success yet achieved in managing human impacts on the global environment. Its arguments about how this success was achieved are both theoretically novel and of great significance for the management of other global problems, particularly global climate change. The book provides an account of the ozone-depletion issues from the first attempts to develop international action in the 1970s to the mature functioning of the present international regime. It examines the parallel developments of politics and negotiations, scientific understanding and controversy, technological progress, and industry strategy that shaped the issue''s development and its effective management. In addition, the book offers important new insights into how the interactions among these domains influenced the formation and adaptation of the ozone regime. Addressing the initial formation of the regime, the book argues that authoritative scientific assessments were crucial in constraining policy debates and shaping negotiated agreements. Assessments gave scientific claims an ability to change policy actors'' behavior that the claims themselves, however well known and verified, lacked. Concerning subsequent adaptation of the regime, the book identifies a series of feedbacks between the periodic revision of chemical controls and the strategic responses of affected industries, which drove rapid application of new approaches to reduce ozone-depleting chemicals. These feedbacks, promoted by the regime''s novel technology assessment process, allowed worldwide use of the chemicals to decline further and faster than even the boldest predictions, by nearly 95 percent within ten years.

A Subtle Balance critically reflects on major trends and enduring challenges over the last four decades of public policy and governance. During this time, a tension has existed between two aims for public decisions: that they be based on the best available evidence and analysis, and that they be fully democratic. This period has seen a continuing drive for more direct citizen engagement in decision-making and governments trying to address major policy issues through novel consultative and collaborative processes. In essays that offer detailed and novel insights into the recent history of specific issues in social policy, environmental policy, and processes of policy advice and decision-making, contributors elaborate on how these trends have played out in diverse areas of practice, what their consequences have been, and how specific institutional reforms could reset the requisite balance between expertise, evidence, and democracy in Canadian public policy. Inspired by the wide-ranging contributions to scholarship and practice of A.R. (Rod) Dobell, A Subtle Balance draws on the influences of distinguished scholars and sophisticated practitioners of public policy to assess recent changes in governance. Contributors include Martin Bunton, Barry Carin, Ian Clark, Rachel Culley, Rod Dobell, Lia Ernst, Jill Horwitz, John Langford, Justin Longo, Michael Prince, Harry Swain, Charles Ungerleider, Josee van Eijndhoven, Michael Wolfson, and David Zussman.

This third edition has been comprehensively updated to reflect the large changes in scientific knowledge and policy debates on climate change since the previous edition in 2009. It provides a concise but thorough overview of the science, technology, economics, policy, and politics of climate change in a single volume. It explains how scientific and policy debates work, outlines the scientific evidence for the reality and seriousness of climate change and the basic atmospheric science that supports it, and discusses policy options and the current state of the policy debate. By pulling these elements together, the book explains why the issue can be so confusing and provides guidance on practical routes forward. Anyone interested in climate change, the global environment, or how science is used in policy debates should read this book. It is the ideal textbook for undergraduate or graduate courses in environmental policy and climate change.
