How the world chooses to respond to climate change reflects a constellation of value judgments. This book explores those value judgments and the arguments surrounding them across a wide array of is- sues in climate policy. This book is, in a sense, a survey of climate ethics; but it is a survey guided by two specific principles. The first is that climate ethics is most valuable when it engages with the details of climate policy. The book does explore high-level moral questions about, say, how to allocate the burdens of cli- mate action across individuals, countries, and generations. At the same time, though, the book tries to shrink the gap between academic ethics and climate policy by delving into more detailed policy questions—questions where a complex array of competing values presents a serious challenge to designing morally sound climate policies. The second guiding principle is that thinking clearly about climate ethics and climate policy requires a firm grasp of the science, economics, and politics of climate change and at least some familiar- ity with the kinds of policies that people might adopt to respond to it. This is why the book begins with a survey of largely nonphilosophical topics, although even there questions of value inevitably arise. I have tried to write a book that would be useful in a range of contexts. Be- cause it assumes no prior knowledge of climate change or climate ethics, the book can serve as a stand-alone introduction for readers approaching these issues for the first time. For more advanced readers, the book serves as a map of the climate ethics landscape and the corresponding academic literature, with endnotes and recommendations for further reading pointing the way vii 19_0877-Morrow.indb 7 10/16/19 6:43 AM viii Preface into the rapidly growing scholarly conversation about the ethics of climate change and climate policy. Scholars or students in advanced courses should treat the book as a starting point, to be supplemented by outside readings that suit their needs and interests—or, on topics where outside readings are scarce or inadequate, by new research of their own. 19_0877-Morrow.indb 8 10/16/19 6:43 AM Acknowledgments I blame Bob Kopp for this book’s existence. He’s the one who lured me into thinking seriously about climate ethics. Since then, I have benefited tremen- dously from talking with him about climate change and climate policy in general and about various aspects of this book in particular. For that, and a quarter century of friendship, I am grateful. The fine folks at Rowman & Littlefield International deserve my thanks, too. Sarah Campbell got the project off the ground, and my editor, Isobel Cowper-Coles, brought it to completion. Their valuable feedback, along with suggestions and criticisms from two reviewers who read the proposal, im- proved the book in important ways. Thanks also to production editor Janice Braunstein, who shepherded the book from digital manuscript to physical form, and copyeditor Naomi Mindlin. I owe a deep intellectual debt to so many ethicists, economists, and policy experts that I cannot hope to name them all here. I hope I haven’t done them too great a disservice in trying to convey some of their ideas in this book. I owe a particularly deep intellectual debt on these matters to my father, Daniel Morrow, who has influenced so much of my thinking about climate policy in particular and about ethics and economics in general. Finally, I am grateful for the support that I have received from my wife, Melissa; from my parents, Daniel and Felicia; and from Simon Nicholson at the Institute for Carbon Removal Law and Policy at American University, who probably regrets telling me I could spend time finishing this book. Though all these people helped bring this book into existence, blame for the book’s faults, defects, and shortcomings belongs entirely to me, not to any of them—especially not Bob. ix 19_0877-Morrow.indb 9 10/16/19 6:43 AM
