Americans are more aware of global warming than they were when this book was first published, and clearly more eager for solutions. Yet still they do not seem to appreciate the scale of the effort that is needed. It’s hard to look at the evidence objectively and not conclude that the situation is desperate. The pace at which change is occurring, combined with increasingly sophisticated analyses of the paleoclimatic record, have prompted many experts to argue not just that we are racing toward the threshold of “dangerous anthropogenic interference,” but that we have already passed it. In a paper published in the fall of 2008, GISS’s James Hansen warned that current CO
2
levels—roughly 385 parts per million—are too high “if humanity wishes to preserve a planet similar to that on which civilization developed.” These levels, he writes, “will need to be reduced … to at most 350 ppm, but likely less than that.” President Obama’s top science adviser, John Holdren, a Harvard physicist, has observed that an “up-to-date look at the evidence makes clear that civilization has already generated dangerous anthropogenic interference in the climate system.”
As many very well-meaning people have pointed out to me, both while I was working on this book and since then, despair is rarely helpful. I understand and to a certain extent agree with the position of those who, for practical purposes, urge hopefulness. In the end, however, how we feel about climate change is irrelevant. Global warming will have a profound effect on us, on our children, and on life on this planet for generations to come. We may be capable of dealing with this problem, or we may not. In either case, we are still responsible.

Many very busy people gave generously of their time and their expertise to make this book possible. A number of them have been named in the preceding pages, but a number have not.
I’d like to thank Tony Weyiouanna, Vladimir Romanovsky, Glenn Juday, Larry Hinzman, Terry Chapin, Donald Perovich, Jacqueline Richter-Menge, John Weatherly, Gunter Weller, Deborah Williams, Konrad Steffen, Russell Huff, Nicolas Cullen, Jay Zwally, Oddur Sigurdsson, and Robert Correll for the help they provided on the chapters concerning the Arctic.
Similarly, I am indebted to Chris Thomas, Jane Hill, William Bradshaw, and Christina Holzapfel for their explication of evolutionary biology; to James Hansen, David Rind, Gavin Schmidt, and Drew Shindell for their lessons in climate modeling; and to Harvey Weiss and Peter deMenocal for sharing their work on ancient civilizations. Pieter van Geel, Pier Vellinga, Wim van der Weegen, Chris Zevenbergen, Dick van Gooswilligen, Jos Hermsen, Hendrik Dek, and Eelke Turkstra were extremely gracious to me when I visited the Netherlands. Robert Socolow, Stephen Pacala, Marty Hoffert, David Hawkins, Barbara Finamore, and Jingjing Qian spent many hours with me discussing mitigation strategies, while Senator John McCain, former vice president Al Gore, Annie Petsonk, James Mahoney, and Under Secretary of State Paula Dobriansky helped me to understand the politics of global warming. Mayor Pete Clavelle kindly showed me around Burlington. Michael Oppenheimer, Richard Alley, Daniel Schrag, and Andrew Weaver were always willing—and able—to answer one last question.
This book began as a series of pieces that appeared in the
New Yorker
magazine. I am deeply grateful to David Remnick for urging—indeed compelling—me to write those pieces. I also want to thank Dorothy Wickenden and John Bennet, who offered much valuable advice; Michael Specter, who provided ideas and encouragement along the way; Louisa Thomas, who generously and ably helped with research; Elizabeth Pearson-Griffiths and Maureen Klier, who copyedited the chapters; and Marisa Pagano, who kindly assisted with the illustrations. I am indebted, too, to Greg Villepique and Yelena Gitlin, who worked so hard to make this book happen.
Gillian Blake and Kathy Robbins guided this project to completion. I am grateful to both of them for their insight and support.
Finally, I want to thank my husband, John Kleiner, who helped in more ways than he should have. Without his peculiar optimism, not a word here would have been written.
The language of science is metric; however, most British and American readers speak—and think—in units like feet, miles, and degrees Fahrenheit. I have used English units where practical and metric units where it seemed clearly more appropriate. For instance, the standard measure of carbon emissions is metric tons. A metric ton weighs 2,205 pounds.
