When Humans Nearly Vanished by Donald R. Prothero Pdf

The fascinating true story of the explosion of the Mount Toba supervolcano--the Earth's largest eruption in the past 28 million years--and its lasting impact on Earth and human evolution Some 73,000 years ago, the huge dome of Mount Toba, in today's Sumatra, Indonesia, began to rumble. A deep vibration shook the entire island. Jets of steam and ash emanated from the summit, followed by an explosion louder than any sound heard by Homo sapiens since our species evolved on Earth. The eruption of the Toba supervolcano released the energy of a million tons of explosives; seven hundred cubic miles of magma spewed outward in an explosion forty times larger than the largest hydrogen bomb and more than a thousand times as powerful as the Krakatau eruption in 1883. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop by five to nine degrees. It took a full decade for Earth to recover to its pre-eruption temperatures. When Humans Nearly Vanished presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide. Human genes today show evidence of a "genetic bottleneck," an effect seen when a population of organisms becomes so small that their genetic diversity is greatly reduced. This group of survivors could be the ancestors of all humans alive today. Donald R. Prothero explores the geological and biological evidence supporting the Toba bottleneck theory; reveals how the explosion itself was discovered; and offers insight into how the world changed afterward and what might happen if such an eruption occurred today. Prothero's riveting account of this calamitous supervolcanic explosion is not to be missed.

World Without Us by Alan Weisman Pdf

Most books about the environment build on dire threats warning of the possible extinction of humanity. Alan Weisman avoids frightening off readers by disarmingly wiping out our species in the first few pages of this remarkable book. He then continues with an astounding depiction of how Earth will fare once we’re no longer around. The World Without Us is a one-of-a-kind book that sweeps through time from the moment of humanity’s future extinction to millions of years into the future. Drawing on interviews with experts and on real examples of places in the world that have already been abandoned by humans—Chernobyl, the Korean DMZ and an ancient Polish forest—Weisman shows both the shocking impact we’ve had on our planet and how impermanent our footprint actually is.

Catastrophe by David Keys Pdf

It was a catastrophe without precedent in recorded history: for months on end, starting in A.D. 535, a strange, dusky haze robbed much of the earth of normal sunlight. Crops failed in Asia and the Middle East as global weather patterns radically altered. Bubonic plague, exploding out of Africa, wiped out entire populations in Europe. Flood and drought brought ancient cultures to the brink of collapse. In a matter of decades, the old order died and a new world—essentially the modern world as we know it today—began to emerge. In this fascinating, groundbreaking, totally accessible book, archaeological journalist David Keys dramatically reconstructs the global chain of revolutions that began in the catastrophe of A.D. 535, then offers a definitive explanation of how and why this cataclysm occurred on that momentous day centuries ago. The Roman Empire, the greatest power in Europe and the Middle East for centuries, lost half its territory in the century following the catastrophe. During the exact same period, the ancient southern Chinese state, weakened by economic turmoil, succumbed to invaders from the north, and a single unified China was born. Meanwhile, as restless tribes swept down from the central Asian steppes, a new religion known as Islam spread through the Middle East. As Keys demonstrates with compelling originality and authoritative research, these were not isolated upheavals but linked events arising from the same cause and rippling around the world like an enormous tidal wave. Keys's narrative circles the globe as he identifies the eerie fallout from the months of darkness: unprecedented drought in Central America, a strange yellow dust drifting like snow over eastern Asia, prolonged famine, and the hideous pandemic of the bubonic plague. With a superb command of ancient literatures and historical records, Keys makes hitherto unrecognized connections between the "wasteland" that overspread the British countryside and the fall of the great pyramid-building Teotihuacan civilization in Mexico, between a little-known "Jewish empire" in Eastern Europe and the rise of the Japanese nation-state, between storms in France and pestilence in Ireland. In the book's final chapters, Keys delves into the mystery at the heart of this global catastrophe: Why did it happen? The answer, at once surprising and definitive, holds chilling implications for our own precarious geopolitical future. Wide-ranging in its scholarship, written with flair and passion, filled with original insights, Catastrophe is a superb synthesis of history, science, and cultural interpretation.

Eruptions that Shook the World by Clive Oppenheimer Pdf

What does it take for a volcanic eruption to really shake the world? Did volcanic eruptions extinguish the dinosaurs, or help humans to evolve, only to decimate their populations with a super-eruption 73,000 years ago? Did they contribute to the ebb and flow of ancient empires, the French Revolution and the rise of fascism in Europe in the 19th century? These are some of the claims made for volcanic cataclysm. Volcanologist Clive Oppenheimer explores rich geological, historical, archaeological and palaeoenvironmental records (such as ice cores and tree rings) to tell the stories behind some of the greatest volcanic events of the past quarter of a billion years. He shows how a forensic approach to volcanology reveals the richness and complexity behind cause and effect, and argues that important lessons for future catastrophe risk management can be drawn from understanding events that took place even at the dawn of human origins.

The Year Without Summer by William K. Klingaman,Nicholas P. Klingaman Pdf

Like Winchester's Krakatoa, The Year Without Summer reveals a year of dramatic global change long forgotten by history In the tradition of Krakatoa, The World Without Us, and Guns, Germs and Steel comes a sweeping history of the year that became known as 18-hundred-and-froze-to-death. 1816 was a remarkable year—mostly for the fact that there was no summer. As a result of a volcanic eruption in Indonesia, weather patterns were disrupted worldwide for months, allowing for excessive rain, frost, and snowfall through much of the Northeastern U.S. and Europe in the summer of 1816. In the U.S., the extraordinary weather produced food shortages, religious revivals, and extensive migration from New England to the Midwest. In Europe, the cold and wet summer led to famine, food riots, the transformation of stable communities into wandering beggars, and one of the worst typhus epidemics in history. 1816 was the year Frankenstein was written. It was also the year Turner painted his fiery sunsets. All of these things are linked to global climate change—something we are quite aware of now, but that was utterly mysterious to people in the nineteenth century, who concocted all sorts of reasons for such an ungenial season. Making use of a wealth of source material and employing a compelling narrative approach featuring peasants and royalty, politicians, writers, and scientists, The Year Without Summer by William K. Klingaman and Nicholas P. Klingaman examines not only the climate change engendered by this event, but also its effects on politics, the economy, the arts, and social structures.

The Vanished by Léna Mauger Pdf

Every year, nearly one hundred thousand Japanese vanish without a trace. Known as the johatsu, or the “evaporated,” they are often driven by shame and hopelessness, leaving behind lost jobs, disappointed families, and mounting debts. In The Vanished, journalist Léna Mauger and photographer Stéphane Remael uncover the human faces behind the phenomenon through reportage, photographs, and interviews with those who left, those who stayed behind, and those who help orchestrate the disappearances. Their quest to learn the stories of the johatsu weaves its way through: A Tokyo neighborhood so notorious for its petty criminal activities that it was literally erased from the maps Reprogramming camps for subpar bureaucrats and businessmen to become “better” employees The charmless citadel of Toyota City, with its iron grip on its employees The “suicide” cliffs of Tojinbo, patrolled by a man fighting to save the desperate The desolation of Fukushima in the aftermath of the tsunami And yet, as exotic and foreign as their stories might appear to an outsider’s eyes, the human experience shared by the interviewees remains powerfully universal.

Vanished Giants by Anthony J. Stuart Pdf

Featuring numerous illustrations, this book explores the many lessons to be learned from Pleistocene megafauna, including the role of humans in their extinction, their disappearance at the start of the Sixth Extinction, and what they might teach us about contemporary conservation crises. Long after the extinction of dinosaurs, when humans were still in the Stone Age, woolly rhinos, mammoths, mastodons, sabertooth cats, giant ground sloths, and many other spectacular large animals that are no longer with us roamed the Earth. These animals are regarded as “Pleistocene megafauna,” named for the geological era in which they lived—also known as the Ice Age. In Vanished Giants: The Lost World of the Ice Age, paleontologist Anthony J. Stuart explores the lives and environments of these animals, moving between six continents and several key islands. Stuart examines the animals themselves via what we’ve learned from fossil remains, and he describes the landscapes, climates, vegetation, ecological interactions, and other aspects of the animals’ existence. Illustrated throughout, Vanished Giants also offers a picture of the world as it was tens of thousands of years ago when these giants still existed. Unlike the case of the dinosaurs, there was no asteroid strike to blame for the end of their world. Instead, it appears that the giants of the Ice Age were driven to extinction by climate change, human activities—especially hunting—or both. Drawing on the latest evidence provided by radiocarbon dating, Stuart discusses these possibilities. The extinction of Ice Age megafauna can be seen as the beginning of the so-called Sixth Extinction, which is happening right now. This has important implications for understanding the likely fate of present-day animals in the face of contemporary climate change and vastly increasing human populations.

No Apparent Danger by Victoria Bruce Pdf

On January 14, 1993, a team of scientists descended into the crater of Galeras, a restless Andean volcano in southern Colombia, for a day of field research. As the group slowly moved across the rocky moonscape of the caldera near the heart of the volcano, Galeras erupted, its crater exploding in a barrage of burning rocks and glowing shrapnel. Nine men died instantly, their bodies torn apart by the blast. While others watched helplessly from the rim, Colombian geologist Marta Calvache raced into the rumbling crater, praying to find survivors. This was Calvache's second volcanic disaster in less than a decade. In 1985 Calvache was part of a group of Colombia's brightest young scientists that had been studying activity at Nevado del Ruiz, a volcano three hundred miles north of Galeras. They had warned of the dire consequences of an eruption for months, but their fledgling coalition lacked the resources and muscle to implement a plan of action or sway public opinion. When Nevado del Ruiz erupted suddenly in November 1985, it wiped the city of Armero off the face of the earth and killed more than twenty-three thousand people -- one of the worst natural disasters of the twentieth century. No Apparent Danger links the characters and events of these two eruptions to tell a riveting story of scientific tragedy and human heroism. In the aftermath of Nevado del Ruiz, volcanologists from all over the world came to Galeras -- some to ensure that such horrors would never be repeated, some to conduct cutting-edge research, and some for personal gain. Seismologists, gas chemists, geologists, and geophysicists hoped to combine their separate areas of expertise to better understand and predict the behavior of monumental forces at work deep within the earth. And yet, despite such expertise, experience, and training, crucial data were ignored or overlooked, essential safety precautions were bypassed, and fifteen people descended into a death trap at Galeras. Incredibly, expedition leader Stanley Williams was one of five who survived, aided bravely by Marta Calvache and her colleagues. But nine others were not so lucky. Expertly detailing the turbulent history of Colombia and the geology of its snow-peaked volcanoes, Victoria Bruce weaves together the stories of the heroes, victims, survivors, and bystanders, evoking with great sensitivity what it means to live in the shadow of a volcano, a hair's-breadth away from unthinkable natural calamity, and shows how clashing cultures and scientific arrogance resulted in tragic and unnecessary loss of life.

The Sixth Extinction by Elizabeth Kolbert Pdf

ONE OF THE NEW YORK TIMES BOOK REVIEW'S 10 BEST BOOKS OF THE YEAR A major book about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes Over the last half a billion years, there have been five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In The Sixth Extinction, two-time winner of the National Magazine Award and New Yorker writer Elizabeth Kolbert draws on the work of scores of researchers in half a dozen disciplines, accompanying many of them into the field: geologists who study deep ocean cores, botanists who follow the tree line as it climbs up the Andes, marine biologists who dive off the Great Barrier Reef. She introduces us to a dozen species, some already gone, others facing extinction, including the Panamian golden frog, staghorn coral, the great auk, and the Sumatran rhino. Through these stories, Kolbert provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy; as Kolbert observes, it compels us to rethink the fundamental question of what it means to be human.

Giants of the Lost World by Donald R. Prothero Pdf

More than a hundred years ago, Sir Arthur Conan Doyle wrote a novel called The Lost World with the exciting premise that dinosaurs and other prehistoric beasts still ruled in South America. Little did Conan Doyle know, there were terrifying monsters in South America--they just happened to be extinct. In fact, South America has an incredible history as a land where many strange creatures evolved and died out. In his book Giants of the Lost World: Dinosaurs and Other Extinct Monsters of South America, Donald R. Prothero uncovers the real science and history behind this fascinating story. The largest animal ever discovered was the huge sauropod dinosaur Argentinosaurus, which was about 130 feet long and weighed up to 100 tons. The carnivorous predator Giganotosaurus weighed in at more than 8 tons and measured more than 47 feet long, dwarfing the T. rex in comparison. Gigantic anacondas broke reptile records; possums evolved into huge saber-toothed predators; and ground sloths grew larger than elephants in this strange, unknown land. Prothero presents the scientific details about each of these prehistoric beasts, provides a picture of the ancient landscapes they once roamed, and includes the stories of the individuals who first discovered their fossils for a captivating account of a lost world that is stranger than fiction.

A Gap in Nature by Tim Fridtjof Flannery,Peter Schouten Pdf

We live in an age of extinction. A Gap in Nature, written by Tim Flannery and breathtakingly illustrated by Peter Schouten, tells the magic story of how, after Columbus' bold discovery of the Americas in 1492, the impact of European exploration and settlement was to prove fatal for many of the planet's most bizarre and extraordinary creatures. Some species disappeared before they could be properly documented, and others became extinct when overzealous collectors shot their last members. Every part of the planet was affected, from the Caribbean to the Arctic North, from the tiniest Pacific island to Eurasia, the great landmass of them all.

Super Volcano by Greg Breining Pdf

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. Yellowstone is one of the world's five "super volcanoes." When it erupts, much of the nation will be hit hard. Though historically Yellowstone has erupted about every 600,000 years, it has not done so for 630,000, meaning it is 30,000 years overdue. Starting with a scenario of what will happen when Yellowstone blows, this fascinating study describes how volcanoes function and includes a timeline of famous volcanic eruptions throughout history.

The Invaders by Pat Shipman Pdf

A Times Higher Education Book of the Week Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe—descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished. Ever since the first Neanderthal bones were identified in 1856, scientists have been vexed by the question, why did modern humans survive while their closest known relatives went extinct? “Shipman admits that scientists have yet to find genetic evidence that would prove her theory. Time will tell if she’s right. For now, read this book for an engagingly comprehensive overview of the rapidly evolving understanding of our own origins.” —Toby Lester, Wall Street Journal “Are humans the ultimate invasive species? So contends anthropologist Pat Shipman—and Neanderthals, she opines, were among our first victims. The relationship between Homo sapiens and Homo neanderthalensis is laid out cleanly, along with genetic and other evidence. Shipman posits provocatively that the deciding factor in the triumph of our ancestors was the domestication of wolves.” —Daniel Cressey, Nature

End of the Megafauna: The Fate of the World's Hugest, Fiercest, and Strangest Animals by Ross D E MacPhee Pdf

The fascinating lives and puzzling demise of some of the largest animals on earth. Until a few thousand years ago, creatures that could have been from a sci-fi thriller—including gorilla-sized lemurs, 500-pound birds, and crocodiles that weighed a ton or more—roamed the earth. These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone. What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses. Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.

Once and Future Giants by Sharon Levy Pdf

Until about 13,000 years ago, North America was home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history--and our part in it--is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face the threat of another great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.
