You've heard of Pangea, the single landmass that broke apart some 175 million years ago to give us our current continents, but what about its predecessors, Rodinia or Columbia? These "supercontinents" from Earth's past provide evidence that land repeatedly joins and separates. While scientists debate what that next supercontinent will look like—and what to name it—they all agree: one is coming.

Own the room with this hilarious collection of fact-tastic myth-busters and jaw-dropping trivia exploring science, history, sport and lesser-known facts from across the universe. Did you know that the Moon has a Bishop? That ostriches DON'T bury their heads in the sand? And that powdered rice was used as cement in the Great Wall of China? What do souls weigh? What can't 60% of the human population smell? And what on earth is rhinotillexomania? And the big one . . . are farts actually invisible? The answers to these questions are all here.

In this updated edition of his authoritative book, MIT atmospheric scientist Kerry Emanuel outlines the basic science of global warming and how the current consensus has emerged. Although it is impossible to predict exactly when the most dramatic effects of global warming will be felt, he argues, we can be confident that we face real dangers. Emanuel warns that global warming will contribute to an increase in the intensity and power of hurricanes and flooding and more rapidly advancing deserts.

The world's oceans are changing at a drastic pace. In response, the people who know the ocean most intimately are taking action for the sake of our shared future. Community scientists track species in California tidepools. Researchers dive into the waters around Sydney to replant kelp forests. Scientists and First Nations communities collaborate to restore clam gardens in the Pacific Northwest.

Books about the origins of humanity dominate bestseller lists, while national newspapers present breathless accounts of new archaeological findings and speculate about what those findings tell us about our earliest ancestors. We are obsessed with prehistory—and, in this respect, our current era is no different from any other in the last three hundred years. In this coruscating work, acclaimed historian Stefanos Geroulanos demonstrates how claims about the earliest humans not only shaped Western intellectual culture, but gave rise to our modern world.

Earth, from space, looks like a shimmering gem suspended in an inky, infinite expanse. But this serene image masks the magnificent and volatile interior forces that make life possible for millions of species on the surface. The placid appearances of our neighboring planets similarly belie their powers—and science fiction-worthy features, like diamond rain.

The world needs to turn away from fossil fuels and use clean, renewable sources of energy as soon as we can. Failure to do so will cause catastrophic climate damage sooner than you might think, leading to loss of biodiversity and economic and political instability. But all is not lost! We still have time to save the planet without resorting to 'miracle' technologies. We need to wave goodbye to outdated technologies, such as natural gas and carbon capture, and repurpose the technologies that we already have at our disposal.

More than half a billion years ago, our world was completely covered by glaciers, a "Snowball Earth" that persisted for millions of years. Incredibly, this unimaginable cold led to the remarkable diversification of life on earth known as the Cambrian explosion. With a geologist's eye and a knack for storytelling, Graham Shields explores when and how such inhospitable conditions enabled animals to evolve, radiate, and diversify into our earliest ancestors.

A straightforward and fact-based exploration of how weather happens, how it relates to climate, and how science answers major questions about Earth as a system.

More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans.

Four geologists and two mountain guides face the brutal beauty of West Antarctica eight hundred miles from the United States main base. Their search reaches far into the treacherous mountains of Marie Byrd Land. Over six weeks of living in tents and traveling by snowmobile, the team endures endless cold and furious blizzards. They cross ice fields and hidden crevasses, which one of the team learns about the hard way.

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It holds the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book, Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

Este livro destina-se a estudantes de graduação, pós-graduação, profissionais (docentes e técnicos) e pesquisadores nas áreas de Geografia, Agronomia, Engenharia florestal, Ciências Ambientais e afins, que tenham interesse em aprofundar o conhecimento de solo como suporte à vida no ecossistema de floresta tropical no Brasil. Em cinco capítulos, o autor oferece uma análise comparativa do processo de mudança de uso e de cobertura da terra em relação ao estoque de carbono (CO2) e mercúrio (Hg) no solo sob sistema florestal e agroflorestal no espaço rural sul-amazônico.

The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species-these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news.

A fascinating, comprehensive, accessible account of conodont fossils—one of paleontology's greatest mysteries. Simon J. Knell takes the listener on a journey through 150 years of scientific thinking, imagining, and arguing. Slowly the animal begins to reveal traces of itself: its lifestyle, its remarkable evolution, its witnessing of great catastrophes, its movements over the surface of the planet, and finally its anatomy. Today the conodont animal remains perhaps the most disputed creature in the zoological world.

Stone walls tell nothing less than the story of how New England was formed, and in Robert Thorson's hands they live and breathe. Millions of years ago, New England's stones belonged to ancient mountains thrust up by prehistoric collisions between continents. Buried again over centuries by forest and soil buildup, the stones gradually worked their way back to the surface, only to become impediments to the farmers cultivating the land in the eighteenth century, who piled them into "linear landfills," a place to hold the stones.

In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness. Distinguished scholar Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America.

In this epochal book, Immanuel Velikovsky, one of the great scientists of modern times, puts the complete histories of our Earth and of humanity on a new basis. He presents the results of his 10-year-long interdisciplinary research in an easily understandable, even entertaining manner. In spite - or even because - of the disgraceful hostility provoked by his theories, this book keeps being of ardent topicality, which in the light of recent scientific research is even growing.

Super Volcanoes revels in the incomparable power of volcanic eruptions past and present, Earth-bound and otherwise, and explores how these eruptions reveal secrets about the worlds to which they belong. Science journalist and volcanologist Robin George Andrews describes the stunning ways in which volcanoes can sculpt the sea, land, and sky, and even influence the machinery that makes or breaks the existence of life.
