THIS EDITION HAS BEEN REPLACED BY A NEWER EDITION..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.

The award-winning book is now revised and expanded.

In 2001 an international panel of distinguished climate scientists announced that 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 story of how scientists reached that conclusion—by way of unexpected twists and turns—was the story Spencer Weart told in The Discovery of Global Warming. Now he brings his award-winning account up to date, revised throughout to reflect the latest science and with a new conclusion that shows how the scientific consensus caught fire among the general world public, and how a new understanding of the human meaning of climate change spurred individuals and governments to action.

How an audacious environmental engineering plan fanned white settlers’ visions for South Africa, stoked mistrust in scientific experts, and gave rise to the Apartheid state.
 
In 1918, South Africa’s climate seemed to be drying up. White farmers claimed that rainfall was dwindling, while nineteenth-century missionaries and explorers had found riverbeds, seashells, and other evidence of a verdant past deep in the Kalahari Desert. Government experts insisted, however, that the rains weren’t disappearing; the land, long susceptible to periodic drought, had been further degraded by settler farmers’ agricultural practices—an explanation that white South Africans rejected. So when the geologist Ernest Schwarz blamed the land itself, the farmers listened. Schwarz held that erosion and topography had created arid conditions, that rainfall was declining, and that agriculture was not to blame. As a solution, he proposed diverting two rivers to the Kalahari’s basins, creating a lush country where white South Africans could thrive. This plan, which became known as the Kalahari Thirstland Redemption Scheme, was rejected by most scientists. But it found support among white South Africans who worried that struggling farmers undermined an image of racial superiority.
 
Green Lands for White Men explores how white agriculturalists in southern Africa grappled with a parched and changing terrain as they sought to consolidate control over a Black population. Meredith McKittrick’s timely history of the Redemption Scheme reveals the environment to have been central to South African understandings of race. While Schwarz’s plan was never implemented, it enjoyed sufficient support to prompt government research into its feasibility, and years of debate. McKittrick shows how white farmers rallied around a plan that represented their interests over those of the South African state and delves into the reasons behind this schism between expert opinion and public perception. This backlash against the predominant scientific view, McKittrick argues, displayed the depth of popular mistrust in an expanding scientific elite.
 
A detailed look at the intersection of a settler society, climate change, white nationalism, and expert credibility, Green Lands for White Men examines the reverberations of a scheme that ultimately failed but influenced ideas about race and the environment in South Africa for decades to come.

This collection examines the uses of quantification in climate science, higher education, and health.
 
Numbers are both controlling and fragile. They drive public policy, figuring into everything from college rankings to vaccine efficacy rates. At the same time, they are frequent objects of obfuscation, manipulation, or outright denial. This timely collection by a diverse group of humanists and social scientists challenges undue reverence or skepticism toward quantification and offers new ideas about how to harmonize quantitative with qualitative forms of knowledge.   

Limits of the Numerical focuses on quantification in several contexts: climate change; university teaching and research; and health, medicine, and well-being more broadly. This volume shows the many ways that qualitative and quantitative approaches can productively interact—how the limits of the numerical can be overcome through equitable partnerships with historical, institutional, and philosophical analysis. The authors show that we can use numbers to hold the powerful to account, but only when those numbers are themselves democratically accountable.
