This book provides a synthesis of the past decade of research into global changes that occurred in the earth system in the past. Focus is achieved by concentrating on those changes in the Earth's past environment that best inform our evaluation of current and future global changes and their consequences for human populations. The book stands as a ten year milestone in the operation of the Past Global Changes (PAGES) Project of the International Geosphere-Biosphere Programme (IGBP). It seeks to provide a quantitative understanding of the Earth’s environment in the geologically recent past and to define the envelope of natural environmental variability against which anthropogenic impacts on the Earth System may be assessed. A set of color overhead transparencies based on the figures in the book is available free on the PAGES website (www.pages-igbp.org) for use in teaching and lecturing.
This landmark volume provides the most comprehensive overview to date of the prehistory and archaeology of the Caddo peoples. The Caddos lived in the Southeastern Woodlands for more than 900 years beginning around AD 800?900, before being forced to relocate to Oklahoma in 1859. They left behind a spectacular archaeological record, including the famous Spiro Mound site in Oklahoma as well as many other mound centers, plazas, farmsteads, villages, and cemeteries. The Archaeology of the Caddo examines new advances in studying the history of the Caddo peoples, including ceramic analysis, reconstructions of settlement and regional histories of different Caddo communities, Geographic Information S...
Science and politics are closely connected in today's global environmental issues. This book focuses on these links in relation to climate change, the threats to wildlife species, and natural hazards and disasters. Study of these reveals the need for more effective international cooperation and the limits of global governance.

Science tells us that a new and dangerous stage in planetary evolution has begun—the Anthropocene, a time of rising temperatures, extreme weather, rising oceans, and mass species extinctions. Humanity faces not just more pollution or warmer weather, but a crisis of the Earth System. If business as usual continues, this century will be marked by rapid deterioration of our physical, social, and economic environment. Large parts of Earth will become uninhabitable, and civilization itself will be threatened. Facing the Anthropocene shows what has caused this planetary emergency, and what we must do to meet the challenge. Bridging the gap between Earth System science and ecological Marxism, Ian...

What do hurricanes, melting glaciers, rising ocean levels, eroding coastlines, worldwide crop damage, food shortages, absence of rainfall, shrinking aquifers, wildfires, and lowered water tables all have in common? These are some of the possible results of an increase in the accumulation of "greenhouse gases" in the atmosphere, commonly referred to as global warming. Scientists study climate change from the perspective of eons of the earth's history as well as the short-term effects of recent human-induced changes in the atmosphere, while engineers attempt to devise technological solutions, and politicians struggle with international protocols and methods of enforcement. The ever-increasing ...
