This volume is an introduction to the study of the earth sciences, a multitude of the earth's composition; geology, which embraces geochemistry, the science the science of the earth's structure; meteorology and climatology, the study of both local and planetary weather; tectonics, the fledgling science of the move­ ment of sections of the earth, of earthquakes, and of volcanoes; biology and agricultural engineering; the water cycle and reclamation; the chemistry of the atmosphere and the origin of the changes it undergoes; the seas, the oceans, or oceanography; beach movement and deserts; hydrology, the science of water from the viewpoint of the sources of energy; pressure and temperature effects; the crust or lithosphere; the hydrosphere, or water areas; the atmosphere, winds, weather, hurricanes, and cyclones, as well as the technology of tracking them; the interfaces of the sections of the planet, and the uses of the earth by its peoples. The human race has developed on the crust and at the interfaces of the land, air, and sea of an unstable planet - a dynamic geological entity whose thermal equilibrium is still millions of years away. The crust of the earth in its movement and cracking evolves earthquakes and volcanoes which are destructive of human work and limit our habitation. Over the last 1500 years, earthquakes have killed as many people as now inhabit the planet, and fifteen times the present U. S. population.

In this concise and accessible text, David P. Turner presents an overview of global environmental change and a synthesis of research from earth system science and sustainability science. It provides a framework for understanding human impact on the environment for anyone interested in our current predicaments and what we can do about them

"The time for a first book on Geoethics has come. The faster, greedier pace of society and globalization demands it. The comfortable life of scholars in the ivory tower is coming to a rude awakening. People demand understandable information on geo-hazards, judges condemn scientist and engineers for lack of communication, indigenous people rise in anger accusing experts of misleading them, attempts to avoid transparency in developments still exist, the helplessness of technology to deal with nuclear waste becomes more evident every day and nature exposes shortcuts in constructing critical facilities with her own awesome force. Less dramatic, but damaging the credibility of the scientific community is the rising number of cases of plagiarism, made easy by the electronic world of communication. In addition, the community of geoscientists needs to become aware of subtle ways in which our work can be useless for or even misleading the public"--

Humans have difficulty thinking at the global scale. Yet as we come to understand our planet as a single, interconnected, complex system and encounter compelling evidence of human impact on Earth's climate and biosphere, the need for a truly global effort is increasingly urgent. In this concise and accessible text, David P. Turner presents an overview of global environmental change and a synthesis of research and ideas from the rapidly evolving fields of earth system science and sustainability science that is suitable for anyone interested in humanity's current predicaments and what we can do about them. The Green Marble examines Earth's past, contemporary human disruption, and the prospects for global environmental governance. Turner emphasizes the functioning of the biosphere--the totality of life on Earth--including its influence on geologic history, its sensitivity to human impacts, and its possible role in ameliorating climate change. Relying on models of the earth system that synthesize vast amounts of monitoring information and recent research on biophysical processes, The Green Marble describes a range of scenarios for our planetary home, exploring the effects of anthropogenic greenhouse gas emissions and factors such as economic globalization. Turner juxtaposes cutting-edge ideas from both the geosciences and the social sciences to illustrate how humanity has arrived upon its current dangerous trajectory, and how we might pull back from the brink of civilization-challenging environmental change. Growing out of the author's popular course on global environmental change, The Green Marble is accessible to non-science majors and provides a framework for understanding the complex relationship of humanity to the global environment
