In this scientifically informed account of the changes occurring in the world over the last century, award-winning broadcaster and natural historian Sir David Attenborough shares a lifetime of wisdom and a hopeful vision for the future.
See the world. Then make it better.
I am 93. I've had an extraordinary life. It's only now that I appreciate how extraordinary.
As a young man, I felt I was out there in the wild, experiencing the untouched natural world - but it was an illusion. The tragedy of our time has been happening all around us, barely noticeable from day to day -- the loss of our planet's wild places, its biodiversity. I have been witness to this decline. A Life on Our Planet is my witness statement, and my vision for the future. It is the story of how we came to make this, our greatest mistake -- and how, if we act now, we can yet put it right.
We have one final chance to create the perfect home for ourselves and restore the wonderful world we inherited. All we need is the will do so.
Are we really just the result of innumerable coincidences? Or is there a more reasonable explanation?
Most of us remember the basics from science classes about how Earth came to be the only known planet that sustains complex life. But what most people don't know is that the more thoroughly researchers investigate the history of our planet, the more astonishing the story of our existence becomes.
The number and complexity of the astronomical, geological, chemical, and biological features recognized as essential to human existence have expanded explosively within the past decade. An understanding of what is required to make possible a large human population and advanced civilizations has raised profound questions about life, our purpose, and our destiny.
This fascinating book helps non-scientists understand the countless miracles that undergird the exquisitely fine-tuned planet we call home--as if Someone had us in mind all along.
The Abiquiu region includes some of the most spectacular and diverse geology in the state of New Mexico. A triple junction of geologic provinces, including the Colorado Plateau, the Rio Grande Rift, and the Jemez Volcanic Field, coincide to tell a fascinating story of landscape evolution in constant change. Abiquiu: The Geologic History of O'Keeffe Country presents the three-hundred-million-year history told by the rocks of the Abiquiu area. With stunning photographs, timelines, and a regional geologic map, noted geologist Kirt Kempter explains the geologic story and landscape evolution of the region for travelers, hikers, and armchair geologists. With large-scale aerial photographs showing major geologic features, explanations of volcanic activity related to the Rio Grande Rift, and detailed descriptions of geologic strata that make up O'Keeffe's beloved Cerro Pedernal, Abiquiu tells the many chapters of changing environments and landscapes from Abiquiu's geologic past.
Traditional histories of the Civil War describe the conflict as a war between North and South. Kenneth Noe, following the lead of environmental historians, suggests instead that it was a war between the North and South and the weather. In The Howling Storm: Climate, Weather, and the American Civil War, Noe retells the entire history of the war with a focus on how climate and weather continually shaped the success and failure of battles and campaigns. He contends that climate and weather blunted Confederate hopes by creating flooding and droughts that constricted Confederate food supply and undermined nationalism and patriotism. Ultimately, he concludes, Union generals such as U. S. Grant as well as Federal logisticians were better able to deal with southern weather and soil, which emerged as a significant factor in an eventual Union victory, a result that weather conditions also ironically delayed. The Howling Storm contributes to Civil War historiography in several ways. First, it rethinks traditional explanations of victories and defeats by factoring in weather conditions. The result is that historians will often have to reconsider what they believe they know about the conflict. By examining the war chronologically, Noe addresses how soldiers and civilians alike coped with weather conditions throughout the war. At the same time, his deep consideration of flood and drought in 1862, 1863, and 1864 reshapes traditional explanations of Confederate defeat. For decades, historians have discussed Confederate taxation and logistical problems without considering the foundational causes that forced Richmond to make tough decisions about whether to prioritise feeding soldiers or civilians. Noe describes the war's weather conditions as unusual, something geographers routinely discuss but Civil War historians have not previously known. He places the Civil War's unusual weather in the context of broader weather phenomena such as El Nino, La Nina, and similar oscillations in the Atlantic Ocean. Noe's work is the first comprehensive examination of weather and climate during the war and is certain to reshape the field in terms of its approach, coverage, and conclusions.

Winds, Waves, and Warriors examines the oceanographic conditions that U.S. military planners considered, or should have considered, when landing troops and vehicles on the beach at three historic amphibious assaults: Normandy, Tarawa, and Inchon. Oceanographer Thomas M. Mitchell brings welcome insight into a little-studied yet extraordinary aspect of ground warfare by explaining why certain tidal and weather conditions existed at those specific places and times, and how they affected the Army and Marine foot soldiers fighting to get ashore. Mitchell offers easy-to-understand descriptions of basic oceanographic concepts and applies them to actual amphibious operations. Winds and waves hampered the Allies' efforts on D-Day but less than they would have had the soldiers attempted storming the beach at Normandy the day before or after. Coral reefs and tides contributed to high Marine casualties at Tarawa Atoll in the Pacific. General Douglas MacArthur used the element of surprise by attacking the North Koreans at Inchon despite treacherous soft mud bottoms and unfavorable tidal conditions. Mitchell details how wartime necessity led to the development of clever methods to estimate such factors as water depth, beach slope, and underwater shoals, all of which affected troops' assaults and potentially changed the outcomes of key battles. An Army Air Corps lieutenant, for example, dug a hole on the beach at Normandy to help him predict tides more accurately. The Army's Beach Erosion Board and research groups such as the Scripps Institution of Oceanography exploited elementary principles of physical oceanography to develop crude but effective instruments and techniques for ocean remote sensing and forecasting. Indeed, soldiers, Marines, staff planners, commanders, oceanographers, meteorologists, and researchers all contributed to some of the largest and most important military invasions in history. Winds, Waves, and Warriors tells of the U.S. military's struggles with a foe that was sometimes just as formidable and unpredictable as the opposing army. When unheeded, unfavorable weather and ocean conditions could lead to tragic and avoidable deaths. The threat posed by the ocean at these three historic battles was an important factor not only in the outcomes of these operations but also to the survival of the troops who fought there.

Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. We have hunted them for thousands of years and scratched their icons into our mythologies. They simultaneously fill us with waves of terror, awe and affection - yet we know hardly anything about them. Whales tend to only enter our awareness when they die, struck by a ship or stranded in the surf. They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Yet despite centuries of observing whales, we know little about their evolutionary past. Palaeontologist Nick Pyenson takes us to the ends of the earth and to the cutting edge of whale research as he searches for the answers to some of our biggest questions about these graceful giants. His rich storytelling takes us deep inside the Smithsonian's unparalleled fossil collection, to frigid Antarctic waters, and to the arid desert of Chile, where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is an illuminating story of scientific discovery that brings readers closer to the most enigmatic and beloved animals of all time.
Rising at 11,750 feet in the Sangre de Cristo range and snaking 926 miles through New Mexico and Texas to the Rio Grande, the Pecos River is one of the most storied waterways in the American West. It is also one of the most troubled. In 1942, the National Resources Planning Board observed that the Pecos River basin ""probably presents a greater aggregation of problems associated with land and water use than any other irrigated basin in the Western U.S."" In the twenty-first century, the river's problems have only multiplied. Bitter Waters, the first book-length study of the entire Pecos, traces the river's environmental history from the arrival of the first Europeans in the sixteenth century to today. Running clear at its source and turning salty in its middle reach, the Pecos River has served as both a magnet of veneration and an object of scorn. Patrick Dearen, who has written about the Pecos since the 1980s, draws on more than 150 interviews and a wealth of primary sources to trace the river's natural evolution and man's interaction with it. Irrigation projects, dams, invasive saltcedar, forest proliferation, fires, floods, flow decline, usage conflicts, water quality deterioration - Dearen offers a thorough and clearly written account of what each factor has meant to the river and its prospects. As fine-grained in detail as it is sweeping in breadth, the picture Bitter Waters presents is sobering but not without hope, as it also extends to potential solutions to the Pecos River's problems and the current efforts to undo decades of damage. Combining the research skills of an accomplished historian, the investigative techniques of a veteran journalist, and the engaging style of an award-winning novelist, this powerful and accessible work of environmental history may well mark a turning point in the Pecos's fortunes.
