Publisher Description
Nature is fragile, environmentalists often tell us. But the lesson of this book is that it is not so. The truth is far more worrying. Nature is strong and packs a serious counterpunch . . . Global warming will very probably unleash unstoppable planetary forces. And they will not be gradual. The history of our planet's climate shows that it does not do gradual change. Under pressure, whether from sunspots or orbital wobbles or the depredations of humans, it lurches-virtually overnight. —from the Introduction
Fred Pearce has been writing about climate change for eighteen years, and the more he learns, the worse things look. Where once scientists were concerned about gradual climate change, now more and more of them fear we will soon be dealing with abrupt change resulting from triggering hidden tipping points. Even President Bush's top climate modeler, Jim Hansen, warned in 2005 that "we are on the precipice of climate system tipping points beyond which there is no redemption."
As Pearce began working on this book, normally cautious scientists beat a path to his door to tell him about their fears and their latest findings. With Speed and Violence tells the stories of these scientists and their work-from the implications of melting permafrost in Siberia and the huge river systems of meltwater beneath the icecaps of Greenland and Antarctica to the effects of the "ocean conveyor" and a rare molecule that runs virtually the entire cleanup system for the planet.
Above all, the scientists told him what they're now learning about the speed and violence of past natural climate change-and what it portends for our future. With Speed and Violence is the most up-to-date and readable book yet about the growing evidence for global warming and the large climatic effects it may unleash.
PUBLISHERS WEEKLY
Pearce (When the Rivers Run Dry) presents some climate modelers' frightening predictions about the consequences of increased global warming. After studying the history of the earth's climate changes, these scientists have learned that, under pressure from natural forces, major shifts can happen abruptly. Today, with the added stress of human interference, irreversible changes could threaten the habitability of our planet. For example, drought and fire could cause the Amazon rainforest to disappear; huge amounts of methane, a greenhouse gas that can be 100 times more powerful than carbon dioxide, could be released by the meltdown of Siberian peat; and aerosol emissions in India and China could end the indispensable Asian monsoon. Hard-line skeptics disagree, of course, but Pearce cites highly respected scientists who assert that the threats have been underestimated, especially by the U.N.'s Intergovernmental Panel on Climate Change. Even President Bush's chief climate modeler notes that the glaciers and ice sheets at the poles are disintegrating at alarming rates and warns that we may be only a decade and one degree of warming away from global catastrophe. The science behind climate studies is complex, but Pearce makes it accessible enough to terrify even the most uninitiated layperson.
