Actually humans did contribute to the climate changes of the seventeenth century, alongside such natural phenomena as the el niño episodes, volcanic eruptions, and the lack of sunspots that parker emphasizes. Ruddimans realisation that the gaseous composition of earths atmosphere is an exquisitely sensitive barometer of changes to life itself represents a great breakthrough.
But i stand with ruddiman the simultaneous upward departures of co2 and ch4 from climate indicators, unique in 420,000 years, is probably an early footprint of humankind. Project muse promotes the creation and dissemination of essential humanities and social science resources through collaboration with libraries, publishers, and scholars worldwide. Ruddimans arguments are never mere speculation.
Eight thousand years ago, had these natural cycles not been interrupted, the earths climate was about to enter a cooling phase that would eventually lead to another ice age. Ruddimans provocative suggestion of early human influence on the atmosphere will draw fire. 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.

In that chapter, parker describes all the environmental anomalies that afflicted earth in the seventeenth centuryunseasonably cold weather, storms, volcanic eruptions, floods in some places, droughts in othersand their impact on harvests and on other aspects of human life. It also offers insight to historians as to how they might think about scientific and environmental processes. The first argument concerns the impact of humans on the natural cycles of the global climate.
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. William ruddiman is a climatologist, now a professor emeritus at the university of virginia. Ruddimans book has already begun to spark an important debate--a debate which economic historians should be eager to follow and join. It is also the culmination of a lifetimes devotion to the scholarly study of that century in all its ramifications political, social, cultural, environmental, and economic. During a period scientists call the pleistocene, from about 2.

William ruddiman is a climatologist, now a professor emeritus at the university of virginia. 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. Few persons could accomplish these goals, but ruddiman does so, and he does it well. 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. Rather than simply generalizing, he provides specific data from both human and natural archives, as well as quotations from the writings of people who lived through that terrible century.
