The oceans, and all that lives in them, are the most precious ecosystems we have on the planet. They maintain the essential balance to keep the planet going and to make life on Earth possible. This book presents the current state of the oceans and highlights the mass destruction that is taking place.

In Tides: The Science and Spirit of the Ocean, writer, sailor, and surfer Jonathan White takes readers across the globe to discover the science and spirit of ocean tides. In the Arctic, White shimmies under the ice with an Inuit elder to hunt for mussels in the dark cavities left behind at low tide; in China, he races the Silver Dragon, a twenty-five-foot tidal bore that crashes eighty miles up the Qiantang River; in France, he interviews the monks that live in the tide-wrapped monastery of Mont Saint-Michel; in Chile and Scotland, he investigates the growth of tidal power generation; and in Panama and Venice, he delves into how the threat of sea level rise is changing human culture—the very old and very new. Tides combines lyrical prose, colorful adventure travel, and provocative scientific inquiry into the elemental, mysterious paradox that keeps our planet’s waters in constant motion. Photographs, scientific figures, line drawings, and sixteen color photos dramatically illustrate this engaging, expert tour of the tides.

From Cnut to D-Day: the history and science of the unceasing tide explored for the first time. Half of the world's population lives in coastal regions lapped by tidal waters. Yet how little most of us know about the tide. Our ability to predict and understand the tide depends on centuries of science, from the observations of Aristotle and the theories of Newton to today's supercomputer calculations. This story is punctuated here by notable tidal episodes in history, from Caesar's thwarted invasion of Britain to the catastrophic flooding of Venice, and interwoven with a rich folklore that continues to inspire art and literature today. With Aldersey-Williams as our guide to the most feared and celebrated tidal features on the planet, from the original maelstrøm in Scandinavia to the world's highest tides in Nova Scotia to the crumbling coast of East Anglia, the importance of the tide, and the way it has shaped - and will continue to shape - our civilization, becomes startlingly clear.

"What if?" questions stimulate people to think in new ways, to refresh old ideas, and to make new discoveries. In What If the Earth Had Two Moons, Neil Comins leads us on a fascinating ten-world journey as we explore what our planet would be like under alternative astronomical conditions. In each case, the Earth would be different, often in surprising ways. The title chapter, for example, gives us a second moon orbiting closer to Earth than the one we have now. The night sky is a lot brighter, but that won't last forever. Eventually the moons collide, with one extra-massive moon emerging after a period during which Earth sports a Saturn-like ring. This and nine and other speculative essays provide us with insights into the Earth as it exists today, while shedding new light on the burgeoning search for life on planets orbiting other stars. Appealing to adult and young adult alike, this book is a fascinating journey through physics and astronomy, and follows on the author's previous bestseller, What if the Moon Didn't Exist?, with completely new scenarios backed by the latest astronomical research.

Driving evolution forward, the Earth's physical environment has challenged the very survival of organisms and ecosystems throughout the ages. With a fresh new perspective, Evolution on Planet Earth shows how these physical realities and hurdles shaped the primary phases of life on the planet. The book's thorough coverage also includes chapters on more proximate factors and paleoenvironmental events that influenced the diversity of life. A team of notable ecologists, evolutionary biologists, and paleontologists join forces to describe drifting continents, extinction events, and climate change -- important topics that continue to shape Earth's inhabitants to this very day. In a world where global change has become an international issue, this book provides a several billion-year evolutionary perspective on what the environment and environmental change means to life.* Provides thorough background information on each topic while introducing cutting-edge research* Features original material solicited from the leading minds in evolutionary biology and geology today* Emphasizes the influence of massive geological forces - continental drift, volcanic activity, sea and tides

Earth Science text for middle school students. Beautifully designed and illustrated in accordance with our signature mastery-based teaching philosophy. 15 chapters, covering all the basic Earth Science topics, including the evidence for an old earth and support for the scientific concensus of human-caused climate change.

The Planet Earth, Second Edition reviews remarkable advances in understanding the physical aspects of the Earth, including technical developments that have made various new types of observation and measurement possible, as well as a deepened understanding of the fundamental laws of nature that have given the necessary basis for the interpretation of many of the complex phenomena concerned. Topics covered include the Van Allen radiation belts, the Mohole project, continental drift and polar wandering, the theory of magnetic storms and aurorae; and the possibility of extra-terrestrial sources of life. This book is comprised of 18 chapters and begins with an overview of the work and achievements of the International Geophysical Year. The reader is then introduced to the Earth's physical properties such as the deep interior, crust, oceans, climate, and geomagnetic field, as well as its origin, age, and possible ultimate fate. Subsequent chapters explore the composition and structure of the Earth's atmosphere; the general circulation of the atmosphere and oceans; the ice ages; meteorology and weather forecasting; and experimental proof of the existence of the ionosphere. The airglow, aurorae and magnetic storms, meteors, cosmic radiation, and radiation belts are also described. The final chapter examines the genesis of life on Earth. This monograph is intended for students and practitioners of planetary and geophysical sciences.

This evocative work addresses the challenge of navigating the accelerating pace of change effectively so that we can live more sustainably, through the medium of stories told from modern science, esoteric and spiritual traditions, and Earth wisdom. By integrating these often-strange bedfellows, as well as by emulating great thinkers and doers from history, Navigating the Tides of Change presents a compelling case that humankind can create a future in harmony with the Earth.

Adam Nicolson explores the marine life inhabiting seashore rockpools with a scientist’s curiosity and a poet’s wonder in this beautifully illustrated book. The sea is not made of water. Creatures are its genes. Look down as you crouch over the shallows and you will find a periwinkle or a prawn, a claw-displaying crab or a cluster of anemones ready to meet you. No need for binoculars or special stalking skills: go to the rocks and the living will say hello. Inside each rock pool tucked into one of the infinite crevices of the tidal coastline lies a rippling, silent, unknowable universe. Below the stillness of the surface course different currents of endless motion—the ebb and flow of the tide, the steady forward propulsion of the passage of time, and the tiny lifetimes of the rock pool’s creatures, all of which coalesce into the grand narrative of evolution. In Life Between the Tides, Adam Nicolson investigates one of the most revelatory habitats on earth. Under his microscope, we see a prawn’s head become a medieval helmet and a group of “winkles” transform into a Dickensian social scene, with mollusks munching on Stilton and glancing at their pocket watches. Or, rather, is a winkle more like Achilles, an ancient hero, throwing himself toward death for the sake of glory? For Nicolson, who writes “with scientific rigor and a poet’s sense of wonder” (The American Scholar), the world of the rock pools is infinite and as intricate as our own. As Nicolson journeys between the tides, both in the pools he builds along the coast of Scotland and through the timeline of scientific discovery, he is accompanied by great thinkers—no one can escape the pull of the sea. We meet Virginia Woolf and her Waves; a young T. S. Eliot peering into his own rock pool in Massachusetts; even Nicolson’s father-in-law, a classical scholar who would hunt for amethysts along the shoreline, his mind on Heraclitus and the other philosophers of ancient Greece. And, of course, scientists populate the pages; not only their discoveries, but also their doubts and errors, their moments of quiet observation and their thrilling realizations. Everything is within the rock pools, where you can look beyond your own reflection and find the miraculous an inch beneath your nose. “The soul wants to be wet,” Heraclitus said in Ephesus twenty-five hundred years ago. This marvelous book demonstrates why it is so. Includes Color and Black-and-White Photographs
