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.

Even if we stopped all carbon dioxide emissions today, the seas will rise three feet by 2050 and nine feet by 2100. This- not drought, species extinction, or excessive heat waves - will be the most dramatic effect of global warming.

To help us understand what happened during the Ice Age, Peter Ward takes us on a tour of other 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 more extensive. 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. Written with an irresistible combination of passion and expertise, The Call of Distant Mammoths is an engaging exploration of the history of life and the importance of humanity as an evolutionary force. "Carefully argued...an intelligent and compelling book."-THE OLYMPIAN, SEATTLE, WASHINGTON "Ward deftly summarizes a large body of scientific literature, simplifying complex ideas for the general reader without condescension."-PUBLISHERS WEEKLY "Did the overkill really happen?...Peter Ward deftly summarizes the arguments...Ward tells (the story) well."-THE NEW SCIENTIST

By looking backward at the course of great extinctions, a paleontologist sees what the future holds. More than 200 million years ago, a cataclysmic event known as the Permian extinction destroyed more than 90 percent of all species and nearly 97 percent of all living things. Its origins have long been a puzzle for paleontologists. 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 that extinction and others, he discovered that the near-total devastation at the end of the Permian period 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 a fascinating, globe-spanning adventure. In Under a Green Sky, Ward explains how the Permian extinction as well as four others happened, and describes the freakish oceans—belching poisonous gas—and sky—slightly green and always hazy—that would have attended them. Those ancient upheavals demonstrate that the threat of climate change cannot be ignored, lest the world's life today—ourselves included—face the same dire fate that has overwhelmed our planet several times before.

Information is more accessible than ever before. If we want to keep up with what's going on in the world, a twenty-four-hour news cycle will provide us with more facts than we can possibly absorb. And yet, this constant stream of data doesn't yield meaningful answers. Why is there political unrest throughout the globe? Why, with all of our technological advances, haven't we eliminated poverty? Why does injustice exist? Why are we here at all? Inventory of the Universe: Assembling an Infinite Number of Puzzle Pieces . . . Perfectly helps us make sense of our questions by starting at the beginning. With the help of a time-traveling reporter named Galacti, Sam Kneller takes us from the Big Bang to the present day, exploring the ways in which 13.8 billion years of intergalactic happenings have led to a human species that thinks, acts, and interacts as it does. For those of us who are ready to escape the limits of our daily perceptions, Inventory of the Universe will open the door to a greater understanding of our world . . . and ourselves.
