Global Biogeochemical Cycles

The interactions of biogeochemical cycles influence and maintain our climate system. Land use and fossil fuel emissions are currently impacting the biogeochemical cycles of carbon, nitrogen and sulfur on land, in the atmosphere, and in the oceans. This edited volume brings together 27 scholarly contributions on the state of our knowledge of earth system interactions among the oceans, land, and atmosphere. A unique feature of this treatment is the focus on the paleoclimatic and paleobiotic context for investigating these complex interrelationships. * Eight-page colour insert to highlight the latest research * A unique feature of this treatment is the focus on the paleoclimatic context for investigating these complex interrelationships.

Describes the transformation/movement of chemical substances in a global context and is designed for courses dealing with some aspects of biogeochemical cycles. Organized in three sections, it covers earth sciences, element cycles and a synthesis of contemporary environmental issues.

Global climate change - rapid, substantial and human induced - may have radical consequences for life on earth. The problem is a complex one, however, demanding a multi-disciplinary approach. A simple cost-benefit analysis cannot capture the essentials, nor can the issue be reduced to an emissions reduction game, as the Kyoto process tries to do. It is much more sensible to adopt an integrative approach, which reveals that global climate change needs to be considered as a spider in a web, a triggering factor for a range of other, related problems - land use changes, water supply and demand, food supply, energy supply, human health, air pollution, etc. But an approach like this, which takes account of all items of knowledge, known and uncertain, does not produce clear-cut, final and popular answers. It does provide useful insights, however, which will allow comprehensive and effective long-term climate strategies to be put into effect. Climate Change: An Integrated Perspective will appeal to a broad spectrum of readers. It is a useful source for the climate-change professionals, such as policy makers and analysts, natural and social scientists. It is also suitable for educationalists, students and indeed anyone interested in the fascinating world of multidisciplinary research underlying our approach to this global change issue.

This book is a natural extension of the SCOPE (Scientific Committee of Problems on the Environment) volumes on the carbon (C), nitrogen (N), phosphorus (P) and sulfur (S) biogeochemical cycles and their interactions (Likens, 1981; Bolin and Cook, 1983). Substantial progress in the knowledge of these cycles has been made since publication of those volumes. In particular, the nature and extent of biological and inorganic interactions between these cycles have been identified, positive and negative feedbacks recognized and the relationship between the cycles and global environmental change preliminarily elucidated. In March 1991, a NATO Advanced Research Workshop was held for one week in Melreux, Belgium to reexamine the biogeochemical cycles of C, N, P and S on a variety of time and space scales from a holistic point of view. This book is the result of that workshop. The biogeochemical cycles of C, N, P and S are intimately tied to each other through biological productivity and subsequently to problems of global environmental change. These problems may be the most challenging facing humanity in the 21 st century. In the broadest sense, "global change" encompasses both changes to the status of the large, globally connected atmospheric, oceanic and terrestrial environments (e. g. tropospheric temperature increase) and change occurring as the result of nearly simultaneous local changes in many regions of the world (e. g. eutrophication).

Global biogeochemical cycles

Over the last decade, the study of cycles as a model for the earth's changing climate has become a new science. Earth Systems Science is the basis for understanding all aspects of anthropogenic global change, such as chemically forced global climate change. The work is aimed at those students interested in the emerging scientific discipline.Earth Systems Science is an integrated discipline that has been rapidly developing over the last two decades. New information is included in this updated edition so that the text remains relevant. This volume contains five new chapters, but of special importance is the inclusion of an expanded set of student exercises.The two senior authors are leading scientists in their fields and have been awarded numerous prizes for their research efforts. * First edition was widely adopted* Authors are highly respected in their field* Global climate change, integral to the book, is now one of the most important issues in atmospheric sciences and oceanography

Biogeochemistry: An Analysis of Global Change deals with changes in the biogeochemistry of the Earth's surface. The book covers the basics about the effect of life on the chemistry of the Earth, with emphasis on the microbial and chemical reactions that occur on land, in the sea, and in the atmosphere. Computer models are used to help understand elemental cycling and ecosystem function. This book is divided into two sections and comprised of 14 chapters. The discussion begins with an overview of the chemical processes controlling the environment in which we live. A simple model for the biogeochemistry of the Earth's surface is described. The chapters that follow examine models that astrophysicists suggest for the origin of chemical elements, as well as models for the formation of the solar system and the planets. The biogeochemical reactions in the atmosphere, lithosphere, and terrestrial biosphere are also described, along with rock weathering on land and the processes that drive the weathering reactions. The reader is introduced to biogeochemical cycling on land; biogeochemistry in freshwater wetlands and lakes, rivers and estuaries, and the sea; and the global water, carbon, sulfur, nitrogen, and phosphorus cycles. The book concludes with the argument that human population growth is the basis of every major environmental issue facing the world today. This book is intended as a textbook for college-level and graduate students who are interested in global change.
