An enthralling and extraordinary adventure vividly charting the mysteries of the deep Earth, the history of our planet, and the latest discoveries about its inner core. The journey to the center of the earth is a voyage like no other we can imagine. Over 3000 km below the earth's surface, an extraordinary inner world the size of Mars awaits us. Dive through the molten iron of the outer core and eventually you will reach a solid sphere —an iron-clad world held within a metal sea and unattached to anything above. At the earth's core is the history of our planet written in temperature and pressure, crystals and minerals ... Our planet appears tranquil from outer space. And yet the arcs of volcanoes, the earthquake zones, and the auroral glow rippling above our heads are testimony to the remarkable happenings within the earth’s core. For thousands of years these phenomena were explained in legend and myth. Only in recent times has the brave new science of seismology emerged. One hundred and fifty years after the extraordinary, imaginative feat of Jules Verne's Journey to the Center of the Earth, David Whitehouse embarks on a voyage of scientific discovery into the heart of our world. Seismologists today reveal a planet astonishingly buried within a planet. We watch as supercomputers convert signals from the ground into three-dimensional scans of subterranean continents. We will visit laboratories where scientists attempt to reproduce the intense conditions at the center of the Earth, travel down the throat of a volcano, look into the deepest hole ever drilled, and imagine a voyage through enormous crystals of iron...all at the center of our incredible Earth.

In the 1990s Richard B. Alley 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. In The Two-Mile Time Machine, Alley tells the fascinating history of global climate changes as revealed by reading the annual rings of ice from cores drilled in Greenland. He explains that humans have experienced an unusually temperate climate compared to the wild fluctuations that characterized most of prehistory. He warns that our comfortable environment could come to an end in a matter of years and tells us what we need to know in order to understand and perhaps overcome climate changes in the future. In a new preface, the author weighs in on whether our understanding of global climate change has altered in the years since the book was first published, what the latest research tells us, and what he is working on next.

Our most compelling resource just might be the ground beneath our feet. When a teaspoon of soil contains millions of species, and when we pave over the earth on a daily basis, what does that mean for our future? What is the risk to our food supply, the planet's wildlife, the soil on which every life-form depends? How much undeveloped, untrodden ground do we even have left? Paul Bogard set out to answer these questions in The Ground Beneath Us, and what he discovered is astounding. From New York (where more than 118,000,000 tons of human development rest on top of Manhattan Island) to Mexico City (which sinks inches each year into the Aztec ruins beneath it), Bogard shows us the weight of our cities' footprints. And as we see hallowed ground coughing up bullets at a Civil War battlefield; long-hidden remains emerging from below the sites of concentration camps; the dangerous, alluring power of fracking; the fragility of the giant redwoods, our planet's oldest living things; the surprises hidden under a Major League ballpark's grass; and the sublime beauty of our few remaining wildest places, one truth becomes blazingly clear: The ground is the easiest resource to forget, and the last we should. Bogard's The Ground Beneath Us is deeply transporting reading that introduces farmers, geologists, ecologists, cartographers, and others in a quest to understand the importance of something too many of us take for granted: dirt. From growth and life to death and loss, and from the subsurface technologies that run our cities to the dwindling number of idyllic Edens that remain, this is the fascinating story of the ground beneath our feet.

To many of us, the Earth’s crust is a relic of ancient, unknowable history. But to a geologist, stones are richly illustrated narratives, telling gothic tales of cataclysm and reincarnation. For more than four billion years, in beach sand, granite, and garnet schists, the planet has kept a rich and idiosyncratic journal of its past. Fulbright Scholar Marcia Bjornerud takes the reader along on an eye-opening tour of Deep Time, explaining in elegant prose what we see and feel beneath our feet. Both scientist and storyteller, Bjornerud uses anecdotes and metaphors to remind us that our home is a living thing with lessons to teach. Containing a glossary and detailed timescale, as well as vivid descriptions and historic accounts, Reading the Rocks is literally a history of the world, for all friends of the Earth.

The past fifteen thousand years - the entire span of human civilization - have witnessed dramatic sea level changes, which began with rapid global warming at the end of the Ice Age, when sea levels were more than 700 feet below modern levels. Over the next eleven millennia, the oceans climbed in fits and starts. These rapid changes had little effect on those humans who experienced them, partly because there were so few people on earth, and also because they were able to adjust readily to new coastlines. Global sea levels stabilised about six thousand years ago except for local adjustments that caused often quite significant changes to places like the Nile Delta. So the curve of inexorably rising seas flattened out as urban civilizations developed in Egypt, Mesopotamia, and South Asia. The earth's population boomed, quintupling from the time of Christ to the Industrial Revolution. The threat from the oceans increased with our crowding along shores to live, fish, and trade. Since 1860, the world has warmed significantly and the ocean's climb has speeded. The sea level changes are cumulative and gradual; no one knows when they will end. The Attacking Ocean tells a tale of the rising complexity of the relationship between humans and the sea at their doorsteps, a complexity created not by the oceans, which have changed but little. What has changed is us, and the number of us on earth.

Almost 14.5 billion years ago, it all started with a BIG BANG and what began as a cloud of gas, dust, and rock eventually took shape and bloomed into a molten sphere. Battered by asteroid collisions, ice ages, and shifting tectonic plates, our fledgling planet finally pushed forth continents. But if you think the earth has calmed down since then—think again! Geological activity continues to sculpt the earth’s landscape, sometimes with terrible consequences for its inhabitants: earthquakes, volcanoes, and tsunamis. In this one-of-a-kind, wild, but true history of Earth, the Sibert Honor medalist Don Brown takes on big concepts with humor and ease.

The first book written about Mongolian and Siberian shamanism by a shaman trained in that tradition. • A thorough introduction to Mongolian and Siberian shamanic beliefs and practices, which, until the collapse of the Soviet Union, were banned from being practiced. • Includes rituals for healing and divination techniques. In traditional Mongolian-Buryat culture, shamans play an important role maintaining the tegsh, the "balance" of the community. They counsel a path of moderation in one's actions and reverence for the natural world, which they view as mother to humanity. Mongolians believe that if natural resources are taken without thanking the spirits for what they have given, those resources will not be replaced. Unlike many other cultures whose shamanic traditions were undermined by modern civilization, shamans in the remote areas of southern Siberia and Mongolia are still the guardians of the environment, the community, and the natural order. Riding Windhorses is the first book written on Mongolian and Siberian shamanism by a shaman trained in that tradition. A thorough introduction to Mongolian/Siberian shamanic beliefs and practices, it includes working knowledge of the basic rituals and various healing and divination techniques. Many of the rituals and beliefs described here have never been published and are the direct teachings of the author's own shaman mentors.

Winner of the 2015 Pulitzer Prize for History Encounters at the Heart of the World concerns the Mandan Indians, iconic Plains people whose teeming, busy towns on the upper Missouri River were for centuries at the center of the North American universe. We know of them mostly because Lewis and Clark spent the winter of 1804-1805 with them, but why don't we know more? Who were they really? In this extraordinary book, Elizabeth A. Fenn retrieves their history by piecing together important new discoveries in archaeology, anthropology, geology, climatology, epidemiology, and nutritional science. Her boldly original interpretation of these diverse research findings offers us a new perspective on early American history, a new interpretation of the American past. By 1500, more than twelve thousand Mandans were established on the northern Plains, and their commercial prowess, agricultural skills, and reputation for hospitality became famous. Recent archaeological discoveries show how these Native American people thrived, and then how they collapsed. The damage wrought by imported diseases like smallpox and the havoc caused by the arrival of horses and steamboats were tragic for the Mandans, yet, as Fenn makes clear, their sense of themselves as a people with distinctive traditions endured. A riveting account of Mandan history, landscapes, and people, Fenn's narrative is enriched and enlivened not only by science and research but by her own encounters at the heart of the world.
