Product Description

The vast majority of scientists agree that human activity has significantly increased greenhouse gases in the atmosphere—most dramatically since the 1970s. In February 2007 the Intergovernmental Panel on Climate Change found that global warming is "unequivocal" and that human-produced carbon dioxide and other greenhouse gases are chiefly to blame, to a certainty of more than 90 percent. Yet global warming skeptics and ill-informed elected officials continue to dismiss this broad scientific consensus. In What We Know About Climate Change, MIT atmospheric scientist Kerry Emanuel outlines the basic science of global warming and how the current consensus has emerged. Although it is impossible to predict exactly when the most dramatic effects of global warming will be felt, he argues, we can be confident that we face real dangers. Emanuel, whose work was widely cited in media coverage of Hurricane Katrina, warns that global warming will contribute to an increase in the intensity and power of hurricanes and flooding and more rapidly advancing deserts.

But just as our actions have created the looming crisis, so too might they avert it. Emanuel calls for urgent action to reduce greenhouse gases and criticizes the media for playing down the dangers of global warming (and, in search of "balance," quoting extremists who deny its existence).

An afterword by environmental policy experts Judith Layzer and William Moomaw discusses how the United States could lead the way in the policy changes required to deal with global warming.

Review
"Emanuel's words are measured and authoritative. His book should help reduce the huge gap between what is understood by the scientific community and what is known by the people who need to know, the public and policymakers."
—James Hansen, NASA Goddard Institute for Space Studies

"Kerry Emanuel's book What We Know About Climate Change is one of the best [books on climate change] and is certainly the shortest. In less time than it takes to eat dinner, the respected atmospheric scientist and Massachusetts Institute of Technology professor filters out the noise and presents clearly the essence of the issues that surround global warming."
— The Plain Dealer

About the Author
Kerry Emanuel is Professor of Atmospheric Science in the Department of Earth, Atmospheric, and Planetary Science at MIT. He is the author of Divine Wind: The History and Science of Hurricanes and Atmospheric Convection. In May 2006 he was named one of Time magazine's "Time 100: The People Who Shape Our World."

Customer Reviews

Brief and Superb Explanation
Dr. Emanuel does a superb job of separating the wheat from the chaff in this little gem. It's virtually impossible for the average layman to separate conspiracy theory nonsense from fear-mongering reading most books and popular press articles on global warming. But Emanuel presents a sound authoritative analysis of what we really do and don't know.
Unlike many other books on global warming, which bury the reader with a plethora of out-of-context quotes, tables of data, and cherry-picked charts, Emanuel presents just enough solid data for the reader to understand the whole issue.
He covers the philosophic underpinnings of different views, the history of global warming, the science, and finally the politics. When put together in this fashion, readers will educate themselves properly.
Before reading this book, I spent months and months reading peer reviewed scientific journal articles, web-site after web-site, and many popular press articles. Had I read Dr. Emanuel's book sooner I could have obtained the same final position with much less work and time invested.

Words of authority
Be forewarned this is a very small book: 82 pages of text, one B&W figure and no references. On a typical page I counted 120 words. I spotted no typos. I found only one sentence where I thought the physical explanation was muddled. The text could provide an excellent narration to a video documentary. A typical citizen needing to get wise about the physics of global warming might be better served by something more than a book without graphics.

Nevertheless, the book is a very quick read and professionals in this field may still enjoy scouring the pages of this book to find out where Professor Emanuel stands on certain issues. I got my money's worth on page 67 where we can read: "Scientists are most effective when they provide sound, impartial advice, but their reputation for impartiality is severely compromised by the shocking lack of political diversity among American academics, who suffer from the kind of group-think that develops in cloistered cultures. Until this profound and well-documented intellectual homogeneity changes, scientists will be suspected of constituting a leftist think tank."

15 of the 82 pages are not Prof. Emanuel's words, but is an "Afterword" provided by other authors. These words carry less authority. For example, the Afterword attributes the melting of the snows of Kilimanjaro to global warming, but some recent scientific research implicates land use changes around Kilimanjaro.

The Afterword also lays out a plan to save us from global warming, with a claim that "addressing global warming could be relatively painless". Here is the plan: "the United States and other industrial economies reduce their emissions by three percent per year between now and mid-century" which will ultimately "reduce global emissions by 75 percent or more". Some of the means to do this provide a chuckle: "driving less aggressively". No account is made for global population growth and global ambitions for prosperity.

Emanuel is spot on, the afterward is pallid and fails critical scrutiny.
Emanuel has written an outstanding survey of the difficulty and methodology of doing climate change science. One comes away convinced that something needs to be done, although Emanuel doesn't prescribe solutions. The afterward, by Judith A. Layzer and William R. Moomaw, is a pallid letdown after the concise and perceptive work of Emanuel. The backgrounds of Layzer and Moomaw are omitted, unforgivable in the context of the discussion. (Layzer is is Associate Professor of Environmental Policy in the Department of Urban Studies and Planning at MIT and Moomaw is Professor of International Environmental Policy and Director of the Center for International Environment and Resource Policy at Tufts). They are guilty of the academic bias that Emanuel talks of and contribute nothing to the issue. What a shame to sully an otherwise useful book with such irrelevance! Five stars for Emanuel's work. One star, at best, for the afterward. I worked as an experimental physicist before retirement and have been appalled by the lack of scientific acumen exhibited by politicians, the public, and some of the scientific community. I'll give this book to friends with a disclaimer about the afterward.
