While a number of gases are implicated in global warming, carbon dioxide is the most important contributor, and in one sense the entire phenomena can be seen as a human-induced perturbation of the carbon cycle. The Global Carbon Cycle offers a scientific assessment of the state of current knowledge of the carbon cycle by the world's leading scientists sponsored by SCOPE and the Global Carbon Project, and other international partners. It gives an introductory over-view of the carbon cycle, with multidisciplinary contributions covering biological, physical, and social science aspects. Included are 29 chapters covering topics including: an assessment of carbon-climate-human interactions; a portfolio of carbon management options; spatial and temporal distribution of sources and sinks of carbon dioxide; socio-economic driving forces of emissions scenarios.

Throughout, contributors emphasize that all parts of the carbon cycle are interrelated, and only by developing a framework that considers the full set of feedbacks will we be able to achieve a thorough understanding and develop effective management strategies.

The Global Carbon Cycle edited by Christopher B. Field and Michael R. Raupach is part of the Rapid Assessment Publication series produced by the Scientific Committee on Problems of the Environment (SCOPE), in an effort to quickly disseminate the collective knowledge of the world's leading experts on topics of pressing environmental concern.

The global environment has been in a state of change since the height of the last glacial maximum of the Pleistocene. Examining this state of flux of both the natural environment and the living organisms that inhabit it, I. G. Simmons’s Global Environmental History ranges from 10,000 BCE to the modern day to present an incredibly rich and deep time overview of how we have come to our current state of ecological crisis.

A far-reaching approach that considers the truly global picture and recognizes the contributions of many disciplines—including the natural sciences, the social sciences, and increasingly, the humanities—Global Environmental History focuses not only on the material world but also on humans’ ideas about the planet and their place on it. Taking as his starting point the major phases of human technological evolution of the last 12,000 years, Simmons considers how these changes have affected the natural world and goes on to assess the response to conditions such as climate change. By putting today’s environmental preoccupations into a long-term perspective, Simmons reveals the history of some current anxieties.

A timely examination of the interrelation of history and nature, Simmons’s book will be welcomed by any concerned reader interested in the origins of the modern environmental crisis.

While the state of California remains one of the most striking and varied landscapes in the world, it has experienced monumental changes since European settlers first set foot there. The past two centuries have witnessed an ongoing struggle between environment and economy, nature and humanity that has left an indelible mark on the region.

Green Versus Gold provides a compelling look at California's environmental history from its Native American past to conflicts and movements of recent decades. Acclaimed environmental historian Carolyn Merchant has brought together a vast storehouse of primary sources and interpretive essays to create a comprehensive picture of the history of ecological and human interactions in one of the nation's most diverse and resource-rich states.

For each chapter, Merchant has selected original documents that give readers an eyewitness account of specific environments and periods, along with essays from leading historians, geographers, scientists, and other experts that provide context and analysis for the documents. In addition, she presents a list of further readings of both primary and secondary sources. Among other topics, chapters examine:

California's natural environment and Native American lands the Spanish and Russian frontiers environmental impacts of the gold rush the transformation of forests and rangelands agriculture and irrigation cities and urban issues the rise of environmental science and contemporary environmental movement.

Merchant's informed and well-chosen selections present a unique view of decades of environmental change and controversy. Historians, educators, environmentalists, writers, students, scientists, policy makers, and others will find the book an enlightening and important contribution to the debate over our nation's environmental history.
