Earthquakes, floods, tsunamis, hurricanes, volcanoes--they stem from the same forces that give our planet life. Earthquakes give us natural springs; volcanoes produce fertile soil. It is only when these forces exceed our ability to withstand them that they become disasters. Together they have shaped our cities and their architecture; elevated leaders and toppled governments; influenced the way we think, feel, fight, unite, and pray. The history of natural disasters is a history of ourselves.

Global climate change is real. It is not new, and it is not fake news. The New York Times began reporting on climate change in the mid-twentieth century: Melting arctic ice in the 1940s. Increasingly warm average temperatures decade after decade. The fossil fuel industry inciting skepticism about global warming. And the United States' reluctance to commit to a reduction in carbon emissions that might negatively impact its economy. The story of human-made climate change unfolds through articles written at the time of the events. It ends with a clear explanation of what's at risk, and what readers can do to help.

In a world where temperatures fluctuate and extreme weather has become commonplace, several populations have already found themselves unable to survive in their homeland. Droughts, flooding, and crop failures have caused famine, while extreme weather events like hurricanes and tornadoes have destroyed homes and, at times, whole villages. The articles in this collection examine the phenomenon of climate refugees, including the reasons they must move, the impact it has on humans and the economy, and examining the politics and other factors that affect their arrival in new countries.

Our world has ended five times: it has been broiled, frozen, poison-gassed, smothered, and pelted by asteroids. In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.

Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.

Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

Ranging across the 4.6 billion year history of the planet, geology is the subject that encompasses almost all that we see around us, in one way or another, and also much that we cannot see, beneath our feet, and on other planets. The fruits of geology provide most of the materials that give us shelter, and most of the energy that drives our modern lives. Within the study of geology lie some of the clues to the extraordinary impact our species is going to play out on the planet, in centuries and millennia to come.

Geophysics is the physics of the Earth. Central to the Earth Sciences today, it encompasses areas such as seismology, volcanism, plate tectonics, gravitational anomalies, and the Earth's magnetic field (present and past, as captured in rocks), all of which give clues to both the structure and the working of the Earth.

In this Very Short Introduction, William Lowrie describes the internal and external processes that affect the planet, as well as the principles and methods of geophysics used to investigate them. He explains how analysis of the seismic waves produced in earthquakes reveals the internal structure of the Earth. Geophysicists have established that the greatest source of energy powering geological processes is the Earth's internal heat. Deep inside the Earth, the temperature is high enough to produce a fluid outer core of molten iron. It is the motion in this molten iron layer that produces the Earth's magnetic field, which shields the planet against harmful radiation from the Sun and outer space, and thus makes the planet habitable. Lowrie describes how the magnetic field also magnetizes rocks during their formation, leaving a permanent record of the ancient field and its direction that geophysicists have learned to use to interpret past motions of the continents and tectonic plates. From analyzes of Earth's deepest interior to measurements made from Earth-orbiting satellites, Lowrie shows how geophysical exploration is vitally important in the search for mineral resources, and emphasizes our need to understand the history of our planet and the processes that govern its continuing evolution.

If a chimpanzee ventures into the territory of a different group, it will almost certainly be killed. But a New Yorker can fly to Los Angeles--or Borneo--with very little fear. Psychologists have done little to explain this: for years, they have held that our biology puts a hard upper limit--about 150 people--on the size of our social groups. But human societies are in fact vastly larger. How do we manage--by and large--to get along with each other?

More people have died exploring underwater caves than climbing Mount Everest, and we know more about deep space than we do about the depths of our oceans. From one of the top cave divers working today—and one of the very few women in her field—Into the Planet blends science, adventure, and memoir to bring readers face-to-face with the terror and beauty of earth’s remaining unknowns and the extremes of human capability.

Jill Heinerth—the first person in history to dive deep into an Antarctic iceberg and leader of a team that discovered the ancient watery remains of Mayan civilizations—has descended farther into the inner depths of our planet than any other woman. She takes us into the harrowing split-second decisions that determine whether a diver makes it back to safety, the prejudices that prevent women from pursuing careers underwater, and her endeavor to recover a fallen friend’s body from the confines of a cave. But there’s beauty beyond the danger of diving, and while Heinerth swims beneath our feet in the lifeblood of our planet, she works with biologists discovering new species, physicists tracking climate change, and hydrogeologists examining our finite freshwater reserves.

In a powerful work of environmental history, Martin Doyle tells the epic story of America and its rivers, from the U.S. Constitution’s roots in interstate river navigation, to the failure of the levees in Hurricane Katrina and the water wars in the west. Through his own travels and his encounters with experts all over the country―a Mississippi River tugboat captain, an Erie Canal lock operator, a project manager buying water rights for farms along the Colorado River―Doyle reveals the central role rivers have played in American history and how vital they are to its future.

Plate tectonics is a revolutionary theory on a par with modern genetics. Yet, apart from the frequent use of cliches such as 'tectonic shift' by economists, journalists, and politicians, the science itself is rarely mentioned and poorly understood. This book explains modern plate tectonics in a non-technical manner, showing not only how it accounts for phenomena such as great earthquakes, tsunamis, and volcanic eruptions, but also how it controls conditions at the Earth's surface, including global geography and climate. The book presents the advances that have been made since the establishment of plate tectonics in the 1960s, highlighting, on the 50th anniversary of the theory, the contributions of a small number of scientists who have never been widely recognized for their discoveries.

Beginning with the publication of a short article in Nature by Vine and Matthews, the book traces the development of plate tectonics through two generations of the theory. First generation plate tectonics covers the exciting scientific revolution of the 1960s and 1970s, its heroes and its villains. The second generation includes the rapid expansions in sonar, satellite, and seismic technologies during the 1980s and 1990s that provided a truly global view of the plates and their motions, and an appreciation of the role of the plates within the Earth 'system'. The final chapter bring us to the cutting edge of the science, and the latest results from studies using technologies such as seismic tomography and high-pressure mineral physics to probe the deep interior. Ultimately, the book leads to the startling conclusion that, without plate tectonics, the Earth would be as lifeless as Venus.

In this highly anticipated sequel to his international bestseller The Old Ways, Macfarlane takes us on an extraordinary journey into our relationship with darkness, burial, and what lies beneath the surface of both place and mind. Traveling through “deep time”―the dizzying expanses of geologic time that stretch away from the present―he moves from the birth of the universe to a post-human future, from the prehistoric art of Norwegian sea caves to the blue depths of the Greenland ice cap, from Bronze Age funeral chambers to the catacomb labyrinth below Paris, and from the underground fungal networks through which trees communicate to a deep-sunk “hiding place” where nuclear waste will be stored for 100,000 years to come. Woven through Macfarlane’s own travels are the unforgettable stories of descents into the underland made across history by explorers, artists, cavers, divers, mourners, dreamers, and murderers, all of whom have been drawn for different reasons to seek what Cormac McCarthy calls “the awful darkness within the world.”

Building Plant Earth presents a description of Earth as a planet, commencing with its physical and chemical evolution out of the primordial solar nebula. The condensation of elements and their redistribution are described, leading into a section dealing with mapping, geophysical and geochemical studies. This establishes the gross structure of the Earth, following which basic principles and processes of plate tectonics are then described, leading to the elucidation of the working of geological cycles. The main thrust of the remainder of the book is a description of the geological evolution of the Earth. Volcanism and seismicity, ice ages and climate, isotopic techniques and age dating, are all treated. The impact of mass extinctions, global-warming and ozone holes are included. The book is illustrated profusely and closes with a number of useful appendices.

Michigan's Pictured Rocks National Lakeshore was established in 1966 to preserve one of the most exquisite freshwater coastal landscapes in North America. Located between Munising and Grand Marais on Lake Superior, the rugged coastline is anchored by the Pictured Rocks cliffs-soaring sandstone fortresses awash with natural pink, green, and brown pigments. While the Pictured Rocks' geologic history is generally well understood by scientists, much of this information is scattered among different sources and not easily accessible to general readers. In Geology and Landscape of Michigan's Pictured Rocks National Lakeshore and Vicinity, William L. Blewett synthesizes published and unpublished information on the park's geologic history and combines it with vivid color photographs, detailed maps, and diagrams of the area.

At 5:36 p.m. on March 27, 1964, a magnitude 9.2. earthquake – the second most powerful in world history – struck the young state of Alaska. The violent shaking, followed by massive tsunamis, devastated the southern half of the state and killed more than 130 people. A day later, George Plafker, a geologist with the U.S. Geological Survey, arrived to investigate. His fascinating scientific detective work in the months that followed helped confirm the then-controversial theory of plate tectonics.

In a compelling tale about the almost unimaginable brute force of nature, New York Times science journalist Henry Fountain combines history and science to bring the quake and its aftermath to life in vivid detail. With deep, on-the-ground reporting from Alaska, often in the company of George Plafker, Fountain shows how the earthquake left its mark on the land and its people -- and on science.

Peter Neill’sThe Once and Future Ocean aspires to do nothing less than transform our relationship with the world’s most promising and imperiled natural element: the ocean and the inter-connected cycles of water, essential for all aspects of human survival in the 21st century. A successor to Rachael Carson’s The Sea Around Us, Aldo Leopold’s Sand County Almanac, and Jonathan Schell’s The Fate of the Earth, The Once and Future Ocean is ambitious in scope yet grounded in actionable, specific ideas and solutions for preserving the health of the world ocean. It explores the ocean's impact on climate, fresh water, food, energy, health, security, sustainable development, community living, and cultural traditions. Beginning with a discursive analysis of the most pertinent issues relating to the present condition of both land and sea, Neill provides a persuasive argument for “why the ocean matters” and how its sustainability and careful use, from mountain-top to abyssal plain, can establish a new paradigm for value and social behavior around which to build a new post-industrial, post-consumption global community. This fundamental shift is directed toward the creation of a “new hydraulic society” wherein water in all its cycles and conveyances will determine how we live – from our buildings and cities to the structures of governance by which we succeed in an increasingly populated world.

In 1956, geologist and Shell Oil researcher Marion King Hubbert delivered a speech that has shaped world energy debates ever since. Addressing the American Petroleum Institute, Hubbert dropped a bombshell on his audience: U.S. oil production would peak by 1970 and decline steadily thereafter. World production would follow the same fate, reaching its peak soon after the turn of the millennium. In battles stretching over decades, Hubbert defended his forecasts against opponents from both the oil industry and government.

Hubbert was proved largely correct during the energy crises of the 1970s and hailed as a "prophet" and an "oracle." Even amid our twenty-first-century fracking boom, Hubbert’s underlying logic holds true—while remaining a source of debate and controversy.

A rich biography of the man behind peak oil, The Oracle of Oil follows Hubbert from his early days as a University of Chicago undergraduate to his first, ill-fated forays into politics in the midcentury Technocracy movement, and charts his rise as a top geologist in the oil industry and energy expert within the U.S. government.

Rain is elemental, mysterious, precious, destructive.

It is the subject of countless poems and paintings; the top of the weather report; the source of the world's water. Yet this is the first book to tell the story of rain.

Cynthia Barnett's Rain begins four billion years ago with the torrents that filled the oceans, and builds to the storms of climate change. It weaves together science—the true shape of a raindrop, the mysteries of frog and fish rains—with the human story of our ambition to control rain, from ancient rain dances to the 2,203 miles of levees that attempt to straitjacket the Mississippi River. It offers a glimpse of our "founding forecaster," Thomas Jefferson, who measured every drizzle long before modern meteorology. Two centuries later, rainy skies would help inspire Morrissey’s mopes and Kurt Cobain’s grunge. Rain is also a travelogue, taking readers to Scotland to tell the surprising story of the mackintosh raincoat, and to India, where villagers extract the scent of rain from the monsoon-drenched earth and turn it into perfume.

Now, after thousands of years spent praying for rain or worshiping it; burning witches at the stake to stop rain or sacrificing small children to bring it; mocking rain with irrigated agriculture and cities built in floodplains; even trying to blast rain out of the sky with mortars meant for war, humanity has finally managed to change the rain. Only not in ways we intended. As climate change upends rainfall patterns and unleashes increasingly severe storms and drought, Barnett shows rain to be a unifying force in a fractured world. Too much and not nearly enough, rain is a conversation we share, and this is a book for everyone who has ever experienced it.

Despite growing evidence of geothermic activity under America's first and foremost national park, it took geologists a long time to realize that there was actually a volcano beneath Yellowstone. And then, why couldn't they find the caldera or crater? Because, as an aerial photograph finally revealed, the caldera is 45 miles wide, encompassing all of Yellowstone. What will happen, in human terms, when it erupts?

Greg Breining explores the shocking answer to this question and others in a scientific yet accessible look at the enormous natural disaster brewing beneath the surface of the United States.

Much has been written about global warming, but the crucial relationship between people and ice has received little focus, until now - and there is a fierce urgency as the problem accelerates. With clarity and insight, geophysicist and a co-winner of the 2007 Nobel Peace Prize, Henry Pollack, paints a compelling portrait of the delicate geological balance between Earth and its ice, and shows why the current rapid loss of ice portends serious consequences in our not-so-distant future.

Whether sculpting mountains, regulating temperatures, influencing ocean currents, or defining the limits of human settlement, ice has shaped - and continues to shape - the world we live in. This important and increasingly relevant book traces the effect of mountain glaciers on supplies of drinking water and agricultural irrigation, as well as the current results of melting permafrost and shrinking Arctic sea ice - a situation that has degraded the habitat of numerous animals and sparked an international race for seabed oil and minerals. Catastrophic possibilities loom, including rising sea levels and subsequent flooding of low-lying regions worldwide.
