Deserts are environments that can be inhospitable even to seasoned explorers. Craig Childs has spent years in the deserts of the American West, and his treks through arid lands in search of water reveal the natural world at its most extreme.

In the beginning, Earth was an inhospitably alien place—in constant chemical flux, covered with churning seas, crafting its landscape through incessant volcanic eruptions. Amid all this tumult and disaster, life began. The earliest living things were no more than membranes stretched across microscopic gaps in rocks, where boiling hot jets of mineral-rich water gushed out from cracks in the ocean floor. In A (Very) Short History of Life on Earth, Henry Gee zips through the last 4.6 billion years with infectious enthusiasm and intellectual rigor.

Author Kevin Grange—former paramedic and park ranger at Yellowstone and Grand Teton—comes face-to-face with North America’s most fearsome predator, Ursus Arctos. His quest takes him from his home in the Tetons to an eerie, mist-shrouded island of gigantic bruins; from the Bear Center at Washington State University—where scientists believe the secrets of hibernation might help treat diabetes, heart disease, and obesity in humans—to the dark underbelly of for-profit wildlife parks, illegal animal trade and black markets hawking bear bile.

In May 2016, Fort McMurray, the hub of Canada’s oil industry and America’s biggest foreign supplier, was overrun by wildfire. The multi-billion-dollar disaster melted vehicles, turned entire neighborhoods into firebombs, and drove 88,000 people from their homes in a single afternoon. Through the lens of this apocalyptic conflagration—the wildfire equivalent of Hurricane Katrina—John Vaillant warns that this was not a unique event, but a shocking preview of what we must prepare for in a hotter, more flammable world.

Most of us have instinctive evidence the world is ending - balmy December days, face-to-face conversation replaced with heads-to-screens zomboidism, a world at constant war, a political system in disarray. We hear some myths and lies so frequently that they feel like truths: Civilization is humankind’s greatest accomplishment. Progress is undeniable. Count your blessings. You’re lucky to be alive here and now. Civilized to Death counters the idea that progress is inherently good, arguing that the "progress" defining our age is analogous to an advancing disease.

Journalist Christopher Ketcham has been documenting the confluence of commercial exploitation and governmental misconduct in this region for over a decade. His revelatory book takes the listener on a journey across these last wild places, to see how capitalism is killing our great commons.

For years, America's national parks have provided public breathing spaces in a world in which such spaces are steadily disappearing, which is why close to 300 million people visit the parks each year. Now, to honor the centennial of the National Park Service, Terry Tempest Williams, the author of the beloved memoir When Women Were Birds, returns with The Hour of Land, a literary celebration of our national parks, what they mean to us, and what we mean to them.

At the heart of Is a River Alive? is a single, transformative idea: that rivers are not mere matter for human use, but living beings, who should be recognized as such in both imagination and law. Macfarlane takes the reader on a mind-expanding global journey into the history, futures, people and places of the ancient, urgent concept. Around the world, rivers are dying from pollution, drought and damming. But a powerful movement is also underway to recognize the lives and the rights of rivers, and to re-animate our relationships with these vast, mysterious presences whose landscapes we share.

Filled to the brim with far-out facts, this wickedly informative narrative from the author of National Geographic's popular Gory Details blog takes us on a fascinating journey through an astonishing new reality. Blending humor and journalism in the tradition of Mary Roach, acclaimed science reporter Erika Engelhaupt investigates the gross, strange, and morbid absurdities of our bodies and our universe.

From Dr. Tim Flannery, one of the world's foremost experts on conservation and ecology, comes a book of immeasurable importance. Hailed by Kirkus Reviews as a "powerful and persuasive" work that is "sure to provoke strong reaction", The Weather Makers is among the finest examinations of climate change ever written.

Renowned neuroscientist Joseph LeDoux digs into the natural history of life on earth to provide a new perspective on the similarities between us and our ancestors in deep time. This pause-resisting survey of the whole of terrestrial evolution sheds new light on how nervous systems evolved in animals, how the brain developed, and what it means to be human. In The Deep History of Ourselves, LeDoux argues that the key to understanding human behavior lies in viewing evolution through the prism of the first living organisms.

Of all the things humans rely on plants for - sustenance, beauty, medicine, fragrance, flavor, fiber - surely the most curious is our use of them to change consciousness: to stimulate or calm, fiddle with or completely alter, the qualities of our mental experience. Take coffee and tea: People around the world rely on caffeine to sharpen their minds. But we do not usually think of caffeine as a drug, or our daily use as an addiction, because it is legal and socially acceptable.

Alone on a small Missouri farm after a thirty-year marriage, Sue Hubbell found a new love—of the winged, buzzing variety. Left with little but the commercial beekeeping and honey-producing business she started with her husband, Hubbell found solace in the natural world. Then she began to write, challenging herself to tell the absolute truth about her life and the things she cared about. Describing the ups and downs of beekeeping from one springtime to the next, A Country Year transports listeners to a different, simpler place.

In Vibrant Matter, the political theorist Jane Bennett, renowned for her work on nature, ethics, and affect, shifts her focus from the human experience of things to things themselves. Bennett argues that political theory needs to do a better job of recognizing the active participation of nonhuman forces in events.

A Short History of Nearly Everything is Bill Bryson's quest to understand everything that has happened from the Big Bang to the rise of civilization. He takes subjects that normally bore the pants off most of us, like geology, chemistry, and particle physics, and aims to render them comprehensible to people who have never thought they could be interested in science. In the company of some extraordinary scientists, Bill Bryson reveals the world in a way most of us have never seen it before.

In 2011, a lone wolf named Slavc set out from his home territory of Slovenia on an epic journey across the Alps. Tracked by a GPS collar, he walked over a thousand miles. In Italy he bumped into a female wolf on a walkabout of her own—the only two wolves for hundreds of square miles—and when they mated, they formed the first pack to call these mountains home in over a century. Today there are more than a hundred wolves in the area, the result of their remarkable meeting.

In the eighteenth century, two men—exact contemporaries and polar opposites—dedicated their lives to the same daunting task: identifying and describing all life on Earth. Carl Linnaeus, a pious Swedish doctor with a huckster’s flair, believed that life belonged in tidy, static categories. Georges-Louis de Buffon, an aristocratic polymath and keeper of France’s royal garden, viewed life as a dynamic swirl of complexities. Each began his task believing it to be difficult but not impossible: How could the planet possibly hold more than a few thousand species—or as many could fit on Noah’s Ark?

Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes listeners into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; and many more examples.

In 1994, a team led by fossil-hunting legend Tim White—"the Steve Jobs of paleoanthropology"—uncovered the bones of a human ancestor in Ethiopia's Afar region. The findings challenged many assumptions about human evolution and repudiated a half-century of paleoanthropological orthodoxy. An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must-listen for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.
