The impact on climate from 200 years of industrial development is an everyday fact of life, but did humankind's active involvement in climate change really begin with the industrial revolution, as commonly believed? Plows, Plagues, and Petroleum has sparked lively scientific debate since it was first published--arguing that humans have actually been changing the climate for some 8,000 years--as a result of the earlier discovery of agriculture.
The "Ruddiman Hypothesis" will spark intense debate. We learn that the impact of farming on greenhouse-gas levels, thousands of years before the industrial revolution, kept our planet notably warmer than if natural climate cycles had prevailed--quite possibly forestalling a new ice age.
Plows, Plagues, and Petroleum is the first book to trace the full historical sweep of human interaction with Earth's climate. Ruddiman takes us through three broad stages of human history: when nature was in control; when humans began to take control, discovering agriculture and affecting climate through carbon dioxide and methane emissions; and, finally, the more recent human impact on climate change. Along the way he raises the fascinating possibility that plagues, by depleting human populations, also affected reforestation and thus climate--as suggested by dips in greenhouse gases when major pandemics have occurred. While our massive usage of fossil fuels has certainly contributed to modern climate change, Ruddiman shows that industrial growth is only part of the picture. The book concludes by looking to the future and critiquing the impact of special interest money on the global warming debate.
In a new afterword, Ruddiman explores the main challenges posed to his hypothesis, and shows how recent investigations and findings ultimately strengthen the book's original claims.
Praise for Princeton's previous editions: "[A]n excellent book summarizing and placing in context the age-old influence of humans on atmospheric composition, climate and global warming."--Nature
Praise for Princeton's previous editions: "If you're not familiar with Ruddiman's hypothesis, you should be. . . . Plows, Plagues, and Petroleum is excellent reading for scientist and nonscientist alike."--James White, Science
Praise for Princeton's previous editions: "Ruddiman's argument makes it clear that there is no 'natural' baseline of climate in the late Holocene from which to reckon the human impact of the past two centuries."--Wolfgang H. Berger, American Scientist
Praise for Princeton's previous editions: "What is most remarkable about Ruddiman's work is the evidence it provides for an initial disruption to the climate system that occurred long before the industrial revolution--around 8,000 years ago. . . . Ruddiman's realisation that the gaseous composition of Earth's atmosphere is an exquisitely sensitive barometer of changes to life itself represents a great breakthrough."--Tim Flannery, Guardian
Praise for Princeton's previous editions: "William Ruddiman's provocative but plausible conclusion is that the economic behavior of humans began to profoundly influence global climate roughly 8000 years ago. . . . Ruddiman's book has already begun to spark an important debate--a debate which economic historians should be eager to follow and join."--Robert Whaples, EH.net
Praise for Princeton's previous editions: "This well-written book does a great job of summarizing complex topics through simple calculations and examples, and provides the right balance of cultural background and scientific data."--Matthew S. Lachniet, Geotimes
