The renowned cave diver takes readers on “a thrill ride into unfamiliar worlds”—exploring the hidden depths of our oceans and sunken caves (Publishers Weekly). 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. In this thrilling firsthand account, Jill Heinerth blends science, adventure, and memoir to bring readers face-to-face with the terror and beauty of earth’s final frontier—and the extremes of human capability. One of the world’s foremost cave divers, Heinerth’s achievements include leading a team that discovered the ancient watery remains of Mayan civilizations and becoming the first person in history to dive deep into an Antarctic iceberg. In Into the Planet, she vividly recounts everything from discovering new species and examining our finite freshwater reserves to the prejudices women face when pursuing careers underwater.

The Huautla in Mexico is the deepest cave in the Western Hemisphere, possibly the world. Shafts reach skyscraper-depths, caverns are stadium-sized, and sudden floods can drown divers in an instant. With a two-decade obsession, William Stone and his 44-member team entered the sinkhole at Sotano de San Augustin. The first camp settled 2,328 feet below ground in a cavern where headlamps couldn't even illuminate the walls and ceiling. The second camp teetered precariously above an underground canyon where two subterranean rivers collided. But beyond that lay the unknown territory -- a flooded corridor that had blocked all previous comers, claimed a diver's life, and drove the rest of the team back. Except for William Stone and Barbara am Ende, who forged on for 18 more days, with no hope of rescue, to set the record for the deepest cave dive in the Western Hemisphere.

“Heart-stopping and relentlessly gripping. Tabor takes us on an odyssey into unfathomable worlds beneath us, and into the hearts of rare explorers who will do anything to get there first.”—Robert Kurson, author of ShadowDivers In 2004, two great scientist-explorers attempted to find the bottom of the world. American Bill Stone took on the vast, deadly Cheve Cave in southern Mexico. Ukrainian Alexander Klimchouk targeted Krubera, a freezing nightmare of a supercave in the war-torn former Soviet republic of Georgia. Both men spent months almost two vertical miles deep, contending with thousand-foot drops, raging whitewater rivers, monstrous waterfalls, mile-long belly crawls, and the psychological horrors produced by weeks in absolute darkness, beyond all hope of rescue. Based on his unprecedented access to logs and journals as well as hours of personal interviews, James Tabor has crafted a thrilling exploration of man’s timeless urge to discover—and of two extraordinary men whose pursuit of greatness led them to the heights of triumph and the depths of tragedy. Blind Descent is an unforgettable addition to the classic literature of true-life adventure, and a testament to human survival and endurance. “Holds the reader to his seat, containing dangers aplenty with deadly falls, killer microbes, sudden burial, asphyxiation, claustrophobia, anxiety, and hallucinations far underneath the ground in a lightless world. Using a pulse-pounding narrative, this is tense real-life adventure pitting two master cavers mirroring the cold war with very uncommonly high stakes.”—Publishers Weekly (starred review) “A fascinating and informative introduction to the sport of cave diving, as well as a dramatic portrayal of a significant man-vs.-nature conflict. . . . What counts is Tabor’s knack for maximizing dramatic potential, while also managing to be informative and attentive to the major personalities associated with the most important cave explorations of the last two decades.”—Kirkus Reviews Includes a 16-pg black and white insert

In this masterful account in the spirit of Bill Bryson and Ian Frazier, a longtime deep-sea diver masterfully weaves together the science and history of Earth's last remaining frontier: the sea. In an age of unprecedented exploration and innovation, our oceans remain largely unknown, and endlessly fascinating: full of mystery, danger, beauty, and inspiration. In Oceans Deep celebrates the daring pioneers who tested the limits of what the human body can endure under water: free divers able to reach 300 feet on a single breath; engineers and scientists who uncovered the secrets of decompression; teenagers who built their own diving gear from discarded boilers and garden hoses in the 1930s; saturation divers who lived under water for weeks at a time in the 1960s; and the trailblazing men who voluntarily breathed experimental gases at pressures sufficient to trigger insanity. Tracing both the little-known history and exciting future of how we travel and study the depths, Streever's captivating journey includes seventeenth-century leather-hulled submarines, their nuclear-powered descendants, a workshop where luxury submersibles are built for billionaire clients, and robots capable of roving unsupervised between continents, revolutionizing access to the ocean. In this far-flung trip to the wild, night-dark place of shipwrecks, trapped submariners, oil wells, innovative technologies, and people willing to risk their lives while challenging the deep, we discover all the adventures our seas have to offer -- and why they are in such dire need of conservation.

Human health depends on the health of the planet. Earth’s natural systems—the air, the water, the biodiversity, the climate—are our life support systems. Yet climate change, biodiversity loss, scarcity of land and freshwater, pollution and other threats are degrading these systems. The emerging field of planetary health aims to understand how these changes threaten our health and how to protect ourselves and the rest of the biosphere. Planetary Health: Protecting Nature to Protect Ourselves provides a readable introduction to this new paradigm. With an interdisciplinary approach, the book addresses a wide range of health impacts felt in the Anthropocene, including food and nutrition, infectious disease, non-communicable disease, dislocation and conflict, and mental health. It also presents strategies to combat environmental changes and its ill-effects, such as controlling toxic exposures, investing in clean energy, improving urban design, and more. Chapters are authored by widely recognized experts. The result is a comprehensive and optimistic overview of a growing field that is being adopted by researchers and universities around the world. Students of public health will gain a solid grounding in the new challenges their profession must confront, while those in the environmental sciences, agriculture, the design professions, and other fields will become familiar with the human consequences of planetary changes. Understanding how our changing environment affects our health is increasingly critical to a variety of disciplines and professions. Planetary Health is the definitive guide to this vital field.

An inside tour of the incredible—and probably dangerous—plans to counteract the effects of climate change through experiments that range from the plausible to the fantastic David Battisti had arrived in Cambridge expecting a bloodbath. So had many of the other scientists who had joined him for an invitation-only workshop on climate science in 2007, with geoengineering at the top of the agenda. We can't take deliberately altering the atmosphere seriously, he thought, because there’s no way we'll ever know enough to control it. But by the second day, with bad climate news piling on bad climate news, he was having second thoughts. When the scientists voted in a straw poll on whether to support geoengineering research, Battisti, filled with fear about the future, voted in favor. While the pernicious effects of global warming are clear, efforts to reduce the carbon emissions that cause it have fallen far short of what’s needed. Some scientists have started exploring more direct and radical ways to cool the planet, such as: Pouring reflective pollution into the upper atmosphere Making clouds brighter Growing enormous blooms of algae in the ocean Schemes that were science fiction just a few years ago have become earnest plans being studied by alarmed scientists, determined to avoid a climate catastrophe. In Hack the Planet, Science magazine reporter Eli Kintisch looks more closely at this array of ideas and characters, asking if these risky schemes will work, and just how geoengineering is changing the world. Scientists are developing geoengineering techniques for worst-case scenarios. But what would those desperate times look like? Kintisch outlines four circumstances: collapsing ice sheets, megadroughts, a catastrophic methane release, and slowing of the global ocean conveyor belt. As incredible and outlandish as many of these plans may seem, could they soon become our only hope for avoiding calamity? Or will the plans of brilliant and well-intentioned scientists cause unforeseeable disasters as they play out in the real world? And does the advent of geoengineering mean that humanity has failed in its role as steward of the planet—or taken on a new responsibility? Kintisch lays out the possibilities and dangers of geoengineering in a time of planetary tipping points. His investigation is required reading as the debate over global warming shifts to whether humanity should Hack the Planet.
