In the 1990s he and his colleagues made headlines with the discovery that the last ice age came to an abrupt end over a period of only three years. Here Alley offers the first popular account of the wildly fluctuating climate that characterized most of prehistory--long deep freezes alternating briefly with mild conditions--and explains that we humans have experienced an unusually temperate climate. But, he warns, our comfortable environment could come to an end in a matter of years."The Two-Mile Time Machine" begins with the story behind the extensive research in Greenland in the early 1990s, when scientists were beginning to discover ancient ice as an archive of critical information about the climate. Drilling down two miles into the ice, they found atmospheric chemicals and dust that enabled them to construct a record of such phenomena as wind patterns and precipitation over the past 110,000 years. The record suggests that "switches" as well as "dials" control the earth's climate, affecting, for example, hot ocean currents that today enable roses to grow in Europe farther north than polar bears grow in Canada. Throughout most of history, these currents switched on and off repeatedly (due partly to collapsing ice sheets), throwing much of the world from hot to icy and back again in as little as a few years.Alley explains the discovery process in terms the general reader can understand, while laying out the issues that require further study: What are the mechanisms that turn these dials and flip these switches? Is the earth due for another drastic change, one that will reconfigure coastlines or send certain regions into severe drought? Will global warming combine with natural variations in Earth's orbit to flip the North Atlantic switch again? Predicting the long-term climate is one of the greatest challenges facing scientists in the twenty-first century, and Alley tells us what we need to know in order to understand and perhaps overcome climate changes in the future.

    Edward O. Wilson eloquently describes how the species of the world became diverse and why that diversity is threatened today as never before. A great spasm of extinction — the disappearance of whole species — is occurring now, caused this time entirely by humans. Unlike the deterioration of the physical environment, which can be halted, the loss of biodiversity is a far more complex problem — and it is irreversible. Defining a new environmental ethic, Wilson explains why we must rescue whole ecosystems, not only individual species. He calls for an end to conservation versus development arguments, and he outlines the massive shift in priorities needed to address this challenge. No writer, no scientist, is more qualified than Edward O. Wilson to describe, as he does here, the grandeur of evolution and what is at stake. "Engaging and nontechnical prose. . . .

    They have destroyed cities and ended civilizations. John Dvorak, the acclaimed author of Earthquake Storms, looks into the early years of volcanology and its "father," Thomas Jaggar. Jaggar was the youngest of five scientists to investigate the explosion of Mount Pelee in Martinique, which leveled the entire city of St. Pierre and killed its entire population in two minutes. This explosion changed science forever, and Jaggar became obsessed with understanding the force of nature that could do this.A colorful cast of scientists wind their way through The Last Volcano, including an escaped slave who became the leading volcanic guide in Hawaii. But the focus is on Jaggar, who was so fixated on volcanology that he moved to a small house overlooking the lava lake of Kilauea, much to the derision of the scientific community.Falling in love a widowed schoolteacher who shared his passion, Jaggar devoted his life to studying volcanic activity and the mysteries beneath the earth's surface. From their precarious perch, this dynamic husband and wife duo would discover a way to predict volcanic eruptions and tsunamis, promote geothermal energy, and theorize new ways to study the ocean bottom.

    Fathoms: The World in the Whale blends natural history, philosophy, and science to explore: How do whales experience ecological change? Will our connection to these storied animals be transformed by technology? What can observing whales teach us about the complexity, splendour, and fragility of life? In Fathoms, we learn about whales so rare they have never been named, whale songs that sweep across hemispheres in annual waves of popularity, and whales that have modified the chemical composition of our planet’s atmosphere. We travel to Japan to board the ships that hunt whales and delve into the deepest seas to discover the plastic pollution now pervading the whale’s undersea environment. In the spirit of Rachel Carson and Rebecca Solnit, Giggs gives us a vivid exploration of the natural world even as she addresses what it means to write about nature at a time of environmental crisis.

    How has the climate changed in the past?How is it changing now?How do we know?And what kind of a future do we want to create?

    By talking through a hundred or so items, Mike Berners-Lee sets out to give us a carbon instinct for the footprint of literally anything we do, buy and think about. He helps us pick our battles by laying out the orders of magnitude. The book ranges from the everyday (foods, books, plastic bags, bikes, flights, baths...) and the global (deforestation, data centres, rice production, the World Cup, volcanoes, ...) Be warned, some of the things you thought you knew about green living may be about to be turned on their head. Never preachy but packed full of information and always entertaining.

    Making use of remarkable scientific discoveries that transform our understanding of how natural systems work, George Monbiot explores a new, positive environmentalism that shows how damaged ecosystems on land and at sea can be restored, and how this restoration can revitalize and enrich our lives. Challenging what he calls his “ecological boredom,” Monbiot weaves together a beautiful and riveting tale of wild places, wildlife, and wild people. Roaming the hills of Britain and the forests of Europe, kayaking off the coast of Wales with dolphins and seabirds, he seeks out the places that still possess something of the untamed spirit he would like to resurrect.He meets people trying to restore lost forests and bring back missing species—such as wolves, lynx, wolverines, wild boar, and gray whales—and explores astonishing evidence that certain species, not just humans, have the power to shape the physical landscape. This process of rewilding, Monbiot argues, offers an alternative to a silent spring: the chance of a raucous summer in which ecological processes resume and humans draw closer to the natural world.

    The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society.This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.

    Pluto is entrenched in our cultural and emotional view of the cosmos, and Neil deGrasse Tyson, award-winning author and director of the Rose Center, is on a quest to discover why. He stood at the heart of the controversy over Pluto's demotion, and consequently Plutophiles have freely shared their opinions with him, including endless hate mail from third-graders. With his inimitable wit, Tyson delivers a minihistory of planets, describes the oversized characters of the people who study them, and recounts how America's favorite planet was ousted from the cosmic hub.

    Climate change is only the most visible of the modifications we've made—up until this point, inadvertently—to the planet. And our current behavior threatens not only our own future but that of countless other creatures. By comparing Earth's story to those of other planets, astrobiologist David Grinspoon shows what a strange and novel development it is for a species to evolve to build machines, and ultimately, global societies with world-shaping influence.Without minimizing the challenges of the next century, Grinspoon suggests that our present moment is not only one of peril, but also great potential, especially when viewed from a 10,000-year perspective. Our species has surmounted the threat of extinction before, thanks to our innate ingenuity and ability to adapt, and there's every reason to believe we can do so again.Our challenge now is to awaken to our role as a force of planetary change, and to grow into this task. We must become graceful planetary engineers, conscious shapers of our environment and caretakers of Earth's biosphere. This is a perspective that begs us to ask not just what future do we want to avoid, but what do we seek to build? What kind of world do we want? Are humans the worst thing or the best thing to ever happen to our planet? Today we stand at a pivotal juncture, and the answer will depend on the choices we make.

    In The Life of the Cosmos, Smolin cuts the Gordian knot of cosmology with a simple, powerful idea: "The underlying structure of our world, " he writes, "is to be found in the logic of evolution." Today's physicists have overturned Newton's view of the universe, yet they continue to cling to an understanding of reality not unlike Newton's own - as a clock, an intricate mechanism, governed by laws which are mathematical and eternally true. Smolin argues that the laws of nature we observe may be in part the result of a process of natural selection which took place before the big bang. Smolin's ideas are based on recent developments in cosmology, quantum theory, relativity and string theory, yet they offer, at the same time, an unprecedented view of how these developments may fit together to form a new theory of cosmology. From this perspective, the lines between the simple and the complex, the fundamental and the emergent, and even between the biological and the physical are redrawn. The result is a framework that illuminates many intractable problems, from the paradoxes of quantum theory and the nature of space and time to the problem of constructing a final theory of physics. As he argues for this new view, Smolin introduces the reader to recent developments in a wide range of fields, from string theory and quantum gravity to evolutionary theory the structure of galaxies. He examines the philosophical roots of controversies in the foundations of physics, and shows how they may be transformed as science moves towardunderstanding the universe as an interrelated, self-constructed entity, within which life and complexity have a natural place, and in which "the occurrence of novelty, indeed the perpetual birth of novelty, can be understood."

    From the first microbes and jawless fishes that evolved into the myriad species we know today-sharks, whales, dolphins, and, of course, humans-Ellis reveals the deep evolutionary mysteries of the sea. Encyclopedic in scope and complemented by more than sixty drawings, Aquagenesis is a fascinating work that will astonish readers with the wonder, richness, and complexity of the evolution of life. "Quite simply, the best account we now have of the origins of human life." (Te Christian Science Monitor)

    It explains how it was a premeditated, orchestrated deception, using science to impose a political agenda. It fooled a majority including most scientists. They assumed that other scientists would not produce science for a political agenda. German Physicist and meteorologist Klaus-Eckart Puls finally decided to look for himself. Here is what he discovered. Ten years ago I simply parroted what the IPCC told us. One day I started checking the facts and data—first I started with a sense of doubt but then I became outraged when I discovered that much of what the IPCC and the media were telling us was sheer nonsense and was not even supported by any scientific facts and measurements. To this day I still feel shame that as a scientist I made presentations of their science without first checking it.…scientifically it is sheer absurdity to think we can get a nice climate by turning a CO2 adjustment knob. This book uses the same approach used in investigative journalism. It examines the Who, What, Where, When, Why, and How.

    Will temperatures rise by 2�C or 8�C over the next hundred years? Will sea levels rise by 2 or 30 feet? The only way that we can accurately answer questions like these is by looking into the distant past, for a comparison with the world long before the rise of mankind.We may currently believe that atmospheric shifts, like global warming, result from our impact on the planet, but the earth's atmosphere has been dramatically shifting since its creation. This book reveals the crucial role that plants have played in determining atmospheric change - and hence the conditions on the planet we know today. Along the way a number of fascinating puzzles arise: Why did plants evolve leaves? When and how did forests once grow on Antarctica? How did prehistoric insects manage to grow so large? The answers show the extraordinary amount plants can tell us about the history of the planet -- something that has often been overlooked amongst the preoccuputations with dinosaur bones and animal fossils.David Beerling's surprising conclusions are teased out from various lines of scientific enquiry, with evidence being brought to bear from fossil plants and animals, computer models of the atmosphere, and experimental studies. Intimately bound up with the narrative describing the dynamic evolution of climate and life through Earth's history, we find Victorian fossil hunters, intrepid polar explorers and pioneering chemists, alongside wallowing hippos, belching volcanoes, and restless landmasses.

    It emphasizes the ways in which the study of sedimentary rocks is used to interpret depositional environments, changes in ancient sea level, and other intriguing aspects of Earth’s history.
