The Late Pennsylvanian was a time of ice ages and associated climate dynamics. A major reduction in Gondwana ice-volume was followed by a prolonged period of relative global warmth, culminating in the last great ice age of the late Paleozoic. It also was a major turning point in the evolution of life on land, when the coal forests of the Middle Pennsylvanian gave way to new kinds of Late Pennsylvanian wetland vegetation, and new kinds of animals appeared. Changes in the terrestrial biota began during the Middle Pennsylvanian, accelerating and proceeding in a spatially complex manner throughout the Late Pennsylvanian. The Late Pennsylvanian is thus a laboratory for studying environmental changes in a glacial world, and for assessing coeval biotic changes, in part to establish the possible links between the two. No book has been dedicated to this time interval, so this volume fills a gap in our understanding of a dynamic Late Pennsylvanian world that is much like the late Cenozoic world.

This interdisciplinary volume examines how nine arid or semi-arid river basins with thriving irrigated agriculture are doing now and how they may change between now and mid-century. The rivers studied are the Colorado, Euphrates-Tigris, Jucar, Limarí, Murray-Darling, Nile, Rio Grande, São Francisco, and Yellow. Engineered dams and distribution networks brought large benefits to farmers and cities, but now the water systems face multiple challenges, above all climate change, reservoir siltation, and decreased water flows. Unchecked, they will see reduced food production and endanger the economic livelihood of basin populations. The authors suggest how to respond to these challenges without loss of food production, drinking water, or environmental health. The analysis of the political, hydrological, and environmental conditions within each basin gives policymakers, engineers, and researchers interested in the water/sustainability nexus a better understanding of engineered rivers in arid lands.

"Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea and introduced the distinctive stone tools of the Clovis culture. Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge that narrative. Their hypothesis places the technological antecedents of Clovis technology in Europe, with the culture of Solutrean people in France and Spain more than 20,000 years ago, and posits that the first Americans crossed the Atlantic by boat and arrived earlier than previously thought."--Back cover.

Ice Age Earth provides the first detailed review of global environmental change in the Late Quaternary. Significant geological and climatic events are analysed within a review of glacial and periglacial history. The melting history of the last ice sheets reveals that complex, dynamic and catastrophic change occurred, change which affected the circulation of the atmosphere and oceans and the stability of the Earth's crust.

It is now the year 2125 and the ice age about which the people on Earth were told is actually starting. The world is in chaos and most of the governments around the world are no longer functioning. The Washburn-Melbanks family, which includes Max and his wife Alice, their two twin daughters, and both sets of grandparents are trying to reach the equatorial region of South America. Max knows that the 'visitors' who came to Earth to tell everyone what was in their near future made a short stop at the equatorial region in the year 2130. If they can get from Minnesota to Columbia and the equatorial region, they may be able to contact the 'visitors' with the hope of being taken to a new planet to which the 'visitors' brought other human beings to try to save the human race. Unfortunately, the going isn't very easy and they have to fight their way through many obstacles before they reach their final destination. Even though they do eventually reach their goal, will they be able to contact the 'visitors' and be taken by them to the new world where other human beings are now living.

"This volume summarizes new developments in understanding the longest-lived icehouse period in Phanerozoic Earth history, the late Paleozoic ice age. Resolving the Late Paleozoic Ice Age in Time and Space provides summaries of existing and new data from the various Gondwanan continental relics, and also reviews stratigraphic successions from the paleotropical and temperate regions of Laurussia that preserve an indirect record of glaciation. It addresses the extent to which records of glaciation indicate protracted, long-term climatic austerity, as opposed to fluctuating, more dynamic climate, and provides new constraints on the timing of glaciation. Additionally, it tackles questions of synchroneity of glaciation across the various Gondwanan continental relics, and timing relationships between near-field and far-field records at greater levels of resolution than has been possible previously. Results point toward a dynamic icehouse regime that is comparable to the Cenozoic icehouse, and away from traditional interpretations of the late Paleozoic ice age as a single, protracted event that involved stable, long-lived ice centers."--Publisher's website.

In 1927, near the town of Folsom, New Mexico, a spectacular discovery altered our understanding of early humans on the American continent. Scientists excavating a bison from the late Pleistocene age discovered a fluted projectile point wedged between the animal’s ribs—forceful evidence that humans existed during the Ice Age together with now-extinct animals. Subsequent discoveries at nearby Clovis introduced scientists to the first large-scale occupation of the Americas—Clovis culture—with a time span of 13,250 to 12,500 years ago. Los Primeros Mexicanos explores the Clovis occupation of Mexico’s northwest region of Sonora. Using extensive primary data concerning specific artifacts, assemblages, and Paleoindian archaeology, Mexican archaeologist Guadalupe Sánchez presents a synopsis and critical review of current data and a unique summary of information about the First People of México that is difficult to find in Spanish and until now not available in English. Sánchez’s essential framework for early Sonora prehistory includes the Sonoran landscape, the biotic communities, a history of investigations, the regional cultural-historical chronology of Sonora, and the Clovis record in the surrounding area. The Sonoran settlement pattern, she asserts, indicates that Clovis groups were hunter-gatherers who exploited a wide range of environments, locating their settlements near lithic sources for tool-making, water sources, large-prey animals, and a variety of edible plants and small animals. In 1592, a Jesuit priest, José de Acosta, chronicled his puzzlement over when man first arrived in the New World. Four hundred years later, the peopling of the American continent is still intensely interesting to scientists and researchers. Los Primeros Mexicanos offers an exhaustive synthesis of available archaeological evidence to shed light on Clovis occupation in Sonora, Mexico.
