Etat : Good. According to University of Washington paleontologist Peter D. Ward, all but one of the major extinction events in the history of the world have been brought on by climate change-the same global warming that occurs today. In Under a Green Sky, he examines the causes of the Permian extinction, an event more than 200 million years ago so cataclysmic that it destroyed more than 90% of all species and nearly 97% of all living things. This near-total devastation was caused by a warming of the earth due to rising levels of carbon dioxide. Ward explains how that extinction, as well as four others, happened, and then applies those chilling lessons to the present day, showing how the ancient past may hold the key to earth's future.…

Paperback. Etat : Good. More than 200 million years ago, a cataclysmic event known as the Permian extinction destroyed more than 90% of all species and nearly 97% of all living things. Its origins have long been a puzzle for paleontologists, and during the 1990s and the early part of this century a great battle was fought between those who thought that death had come from above and those who thought something more complicated was at work. Paleontologist Peter D. Ward, fresh from helping prove that an asteroid had killed the dinosaurs, turned to the Permian problem, and he has come to a stunning conclusion. In his investigations of the fates of several groups of mollusks during those extinctions and others, he discovered that the near-total devastation at the end of the Permian was caused by rising levels of carbon dioxide leading to climate change. But it's not the heat (nor the humidity) that's directly responsible for the extinctions, and the story of the discovery of what is responsible makes for an fascinating, globe-spanning adventure.…

Hardback. Etat : Good. They deftly bring together findings from many disparate areas of science in a book that science buffs will find hard to put down. --Publishers Weekly Science has worked hard to piece together the story of the evolution of our world up to this point, but only recently have we developed the understanding and the tools to describe the entire life cycle of our planet. Peter D. Ward and Donald Brownlee, a geologist and an astronomer respectively, are in the vanguard of the new field of astrobiology. Combining their knowledge of how the critical sustaining systems of our planet evolve through time with their understanding of how stars and solar systems grow and change throughout their own life cycles, the authors tell the story of the second half of Earth's life. In this masterful melding of groundbreaking research and captivating, eloquent science writing, Ward and Brownlee provide a comprehensive portrait of Earth's life cycle that allows us to understand and appreciate how the planet sustains itself today, and offers us a glimpse of our place in the cosmic order.…

Hardback. Etat : Good. For 65 million years dinosaurs ruled the Earth--until a deadly asteroid forced their extinction. But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures--real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment--a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story. …

Paperback. Etat : Very Good. Why are the great mammals that once walked the earth now largely extinct outside of Africa? Of the two suspected culprits, climate change and human hunting, Ward builds a compelling case for human hunting. Humans arrived in Australia about 40,000 years ago, and the marsupial lions and giant kangaroos vanished soon after; they came to New Zealand 2,000 years ago, and the giant moa was quickly gone; and the American extinction coincides with the spread of the first human population there. In order to understand what happened in the Ice Age, Ward takes us on a tour of mass extinctions through earth's history. He presents a compelling account of the great comet crash that killed off the dinosaurs and describes other extinctions that were even worse. In so doing he introduces us to a profound paradigm shift now taking place in paleontology: rather than arising from the gradual workings of everyday forces, all mass extinctions are due to unique, catastrophic events. They throw a wild card into the game of evolution and start the contest anew.…
