Product Description

THIS EDITION HAS BEEN REPLACED BY A NEWER EDITION..

In 2001 a panel representing virtually all the world's governments and climate scientists announced that they had reached a consensus: the world was warming at a rate without precedent during at least the last ten millennia, and that warming was caused by the buildup of greenhouse gases from human activity. The consensus itself was at least a century in the making. The story of how scientists reached their conclusion--by way of unexpected twists and turns and in the face of formidable intellectual, financial, and political obstacles--is told for the first time in The Discovery of Global Warming. Spencer R. Weart lucidly explains the emerging science, introduces us to the major players, and shows us how the Earth's irreducibly complicated climate system was mirrored by the global scientific community that studied it.

Unlike familiar tales of Science Triumphant, this book portrays scientists working on bits and pieces of a topic so complex that they could never achieve full certainty--yet so important to human survival that provisional answers were essential. Weart unsparingly depicts the conflicts and mistakes, and how they sometimes led to fruitful results. His book reminds us that scientists do not work in isolation, but interact in crucial ways with the political system and with the general public. The book not only reveals the history of global warming, but also analyzes the nature of modern scientific work as it confronts the most difficult questions about the Earth's future.

From Publishers Weekly
It took a century for scientists to agree that gases produced by human activity were causing the world to warm up. Now, in an engaging book that reads like a detective story, physicist Weart (Scientists in Power; Nuclear Fear) reports the history of global warming theory, including the internal conflicts plaguing the research community and the role government has had in promoting climate studies. Some researchers, he writes, pursued red herrings, while others on the right track often could not get attention or funding. Still others made classic errors but uncovered significant seeds of truth in the process. With just enough scientific detail and plenty of biographical narrative, Weart conveys the difficulties of studying vast, chaotic weather systems. As one of the profiled researchers puts it, the earth's climate is "a capricious beast"; instead of taking its threat seriously, he says, we have been "poking it with a sharp stick." Weart's goal is "to help the reader understand our predicament by explaining how we got here." Blending parallel stories, he implies that although geophysicists took a long time to understand the various elements of global warming, they were all working toward a common goal. Without resorting to fear-mongering, Weart gives an informed history and offers his readers solutions to consider.

From Booklist
As Weart makes clear, global warming came to be accepted through a long process of incremental research rather than a dramatic revelation. The story goes back to the mid-nineteenth century, when a French scientist wondered why the earth didn't bake to a crisp, and proposed that the planet radiated infrared energy. But when the Frenchman crunched the numbers, the equations indicated that the earth should be frigid, demonstrating that something in addition to solar energy influenced climate. The search for that something over the past 150 years eventually included the gases and aerosols humanity produces, but interestingly, given contemporary awareness and anxiety about warming, cold was what initially gave scientists the shivers. Specifically, the cause of the ice ages was the target of many scientists' projects. Weart's presiding theme is how different disciplines, working on unrelated problems, have synthesized into the geophysics of cold and warm spells on a planetary scale. A soberly written synthesis of science and politics. Gilbert Taylor

From the Back Cover
A Capricious Beast Ever since the days when he had trudged around fossil lake basins in Nevada for his doctoral thesis, Wally Broecker had been interested in sudden climate shifts. The reported sudden jumps of CO2 in Greenland ice cores stimulated him to put this interest into conjunction with his oceanographic interests. The result was a surprising and important calculation. The key was what Broecker later described as a "great conveyor belt'"of seawater carrying heat northward. . . . The energy carried to the neighborhood of Iceland was "staggering," Broecker realized, nearly a third as much as the Sun sheds upon the entire North Atlantic. If something were to shut down the conveyor, climate would change across much of the Northern Hemisphere… There was reason to believe a shutdown could happen swiftly. In many regions the consequences for climate would be spectacular. Broecker was foremost in taking this disagreeable news to the public. In 1987 he wrote that we had been treating the greenhouse effect as a 'cocktail hour curiosity,' but now 'we must view it as a threat to human beings and wildlife.' The climate system was a capricious beast, he said, and we were poking it with a sharp stick. (20031005)
