This book studies the history and gives an analysis of extreme climate change on Earth. In order to provide a long-term perspective, the first chapter briefly reviews some of the wild gyrations that occurred in the Earth’s climate hundreds of millions of years ago: snowball Earth and hothouse Earth. Coming closer to modern times, the effects of continental drift, particularly the closing of the Isthmus of Panama are believed to have contributed to the advent of ice ages in the past three million years. This first chapter sets the stage for a discussion of ice ages in the geological recent past (i.e. within the last three million years, with an emphasis on the last few hundred thousand years). The second chapter discusses geological evidence for ice ages – how geologists surmised their existence prior to actual subsurface data that proved the theory. The following two chapters look at ice cores (primarily from Greenland and Antarctica). Chapter 3 discusses how ice core data is processed and Chapter 4 summarizes data obtained from ice cores. Chapter 5 discusses the processing of data obtained from ocean sediments, and summarizes the results, while the following chapter discusses data from other sources, such as "Devil’s Cave." Chapter 7 summarizes the experimental results from Chapters 4, 5, and 6. It provides the foundation for comparison with theories in later chapters. In a perfect world, this data would be totally separate and disconnected from theory. Unfortunately, as the author shows, dating of much of the data was accomplished by "tuning" to the astronomical theory, which introduces circular reasoning. Chapter 8 provides a brief overview of the various theories that have been devised to "explain" the patterns of alternating ice ages and interglacials that have occurred over the past three million years. This serves as an introduction to the following three chapters which presents the astronomical theory in its various manifestations, compare the astronomical theory with data, and then compare other theories with data. Finally, Chapter 12 summarizes what we think we know about ice ages and, more importantly, what we don’t know.
A mesmerizing overview of the world as it was when glaciers covered the earth and long-extinct creatures like the woolly mammoths and saber-toothed cats battled to survive. Go back 20,000 years ago to a time of much colder global temperatures when glaciers and extensive sheets of ice covered much of our planet. As these sheets traveled, they caused enormous changes in the Earth's landscape and climate, leading to the evolution of creatures such as giant armadillos, saber-toothed cats, and woolly mammoths as well as club-wielding Neanderthals and later the cleverer modern humans. Nico Medina re-creates this harsh ancient world in a vivid and easy-to-read narrative.
Never short of questions, let these titles bring answers to children who may just want to know, or who may be struggling in their walk with Christ. Parents and teachers need not be afraid of hte tough questions with these solid aplogetics titles in The Answers Book for Kids series. Too many children have grown up and left the Church because they asked tough questions and no one seemed to have an answer. Now, here are those answers! Where was the Tower of Babel built? How many languages came from Babel? Have you ever found a frozen person from the Ice Age?
The intriguing theory of a land bridge periodically linking Siberia and Alaska during the coldest pulsations of the Ice Ages had been much debated since Jose de Acosta, a Spanish missionary working in Mexico and Peru, first proposed the idea of a connection between the continents in 1589. But proof of the land bridge - now named Beringia after eighteenth-century Danish explorer Vitus Bering - eluded scientists until an inquiring geologist named Dave Hopkins emerged from rural New England and set himself to the task of solving the mystery. Through the life story of Hopkins, The Last Giant of Beringia reveals the fascinating science detective story that at last confirmed the existence of the land bridge that served as the intercontinental migration route for such massive Ice Age beasts as woolly mammoths, steppe bison, giant stag-moose, dire wolves, short-faced bears, and saber-toothed cats - and for the first humans to enter the New World from Asia. After proving unambiguously that the land bridge existed, Hopkins went on to show that the Beringian landscape cannot have been the "polar desert" that many had claimed, but provided forage enough to sustain a diverse menagerie of Ice Age behemoths.
Our climate is changing fast. The future is uncertain, probably fiery, and likely terrifying. Yet shifting weather patterns have threatened humans before, right here in North America, when people first colonized this continent. About 15,000 years ago, the weather began to warm, melting the huge glaciers of the Late Pleistocene. In this brand new landscape, humans managed to adapt to unfamiliar habitats and dangerous creatures in the midst of a wildly fluctuating climate. What was it like to live with huge pack-hunting lions, saber-toothed cats, dire wolves, and gigantic short-faced bears, to hunt now extinct horses, camels, and mammoth? Are there lessons for modern people lingering along this ancient trail? The shifting weather patterns of today—what we call "global warming"—will far exceed anything our ancestors previously faced. Doug Peacock's latest narrative explores the full circle of climate change, from the death of the megafauna to the depletion of the ozone, in a deeply personal story that takes readers from Peacock's participation in an archeological dig for early Clovis remains in Livingston, MT, near his home, to the death of the local whitebark pine trees in the same region, as a result of changes in the migration pattern of pine beetles with the warming seasons.
