When it comes to global warming, most people think there are two camps: “alarmist” or “denier” being their respective pejoratives. Either you acknowledge the existence of man-made climate change and consider it a dire global threat, or you deny it exists at all. But there is a third group: the “lukewarmers.” In Lukewarming: The New Climate Science that Changes Everything, Pat Michaels and Chip Knappenberger explain the real science and spin behind the headlines and come to a provocative conclusion: global warming is not hot—it’s lukewarm. Climate change is real, it is partially man-made, but it is clearer than ever that its impact has been exaggerated—with many of the headline-grabbing predictions now being rendered implausible or impossible.

This new paperback edition of the book is a revised and expanded edition of last year's ebook-only edition of Lukewarming. This new edition includes updates in science and policy following the accords reached at the 2015 United Nations Climate Change Conference in Paris. This fresh analysis is an invaluable source for those looking to be more informed about global warming and the data behind it.

"Pat Michaels and Paul Knappenberger are real climate scientists, who think that man-made global warming is real. But they refuse to buy into the politicized pseudoscience that has increasingly been used to buttress the case that global warming is also likely to be dangerous. For this they have been routinely vilified. In this light but serious book, they expose many shocking myths about climate change and make a devastating case for lukewarming."
—Matt Ridley, author of The Rational Optimist

"This is a splendid book that will help any interested person understand not only the latest advances in honest climate science, but also the nonscientific machinations of the climate movement. I look forward to having a copy of the book in my own library."
—Will Happer, Cyrus Fogg Brackett Professor of Physics at Princeton University

"This book is a model of good science. Bad scientists ignore uncomfortable facts; good scientists embrace them. The environmental facts are that the globe is, yet again, warming—but only gently. Pat Michaels describes himself, wittily, as a lukewarmer, and in this witty but penetrating book he shows how good science and sane policies can march together to benefit us all."
—Terence Kealey, Vice Chancellor of the University of Buckingham
