Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea. The presence of these early New World people was established by distinctive stone tools belonging to the Clovis culture. But are the Clovis tools Asian in origin? Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge the old narrative.

Al Gore has been advocating on Earth's behalf for 25 years. In An Inconvenient Sequel, he recounts and contextualizes the critical issues and moments in the climate change movement since the release of An Inconvenient Truth more than 10 years ago and highlights the real solutions we have at hand to change the planet for the better.

The story behind Dr. Gerta Keller’s world-shattering scientific discovery that dinosaur extinction was NOT caused by asteroid impact, but rather by a series of volcanic eruptions on the Indian peninsula, a discovery that highlights today’s existential threat of greenhouse gasses and climate change—and one that sparked an all-out war waged by the male scientific establishment.

Nikola Tesla (1856 -1943) was a Serbian American inventor, engineer, and physicist. In his work Talking with Planets, the prodigious inventor describes receiving radio waves from nonterrestrial sources.

Those now notorious intercepted emails documenting leading scientists conspiring to squelch global-warming skeptics and falsifying data proved exactly what Brian Sussman has been saying for years. Climategate is intended for anyone who has ever expressed skepticism about the clamorous environmentalist claims that the Earth is in peril because of mankind's appetite for carbon-based fuels.

In just the past twenty years, we have learned more about dinosaurs than we did in the previous two centuries. This book describes the extraordinary advances in palaeontology that are beginning to solve many of the mysteries surrounding these marvelous prehistoric creatures, from their ways of communicating to their mating habits, the colour of their skin, their migration patterns and extinction. How did dinosaurs rear their young? What did they eat? What did T. rex actually do with those tiny arms?

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.

This fascinating yet disquieting audiobook finds that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are, and have long been, using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations.

A preeminent geneticist hunts the Neanderthal genome to answer the biggest question of them all: what does it mean to be human? What can we learn from the genes of our closest evolutionary relatives? Neanderthal Man tells the story of geneticist Svante Pbo’s mission to answer that question, beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in his sequencing of the Neanderthal genome in 2009.

A geologist’s revelatory invitation to discover how our planet’s seemingly inert bones pulse with unexpected vitality If you listen, can you hear the stones speak? The question seems absurd. After all, rocks are lifeless, inert, and silent. In The Whispers of Rock, earth scientist...

Freeman Dyson is a world-renowned astrophysicist who dreams of exploring the heavens and has designed a spaceship to take him there. His son, George, a brilliant high-school dropout, lives in a tree house and is designing a giant kayak to explore the icy coastal wilderness of the Pacific Northwest and Alaska.

The conditions that allowed humans to live on this earth are fragile, incredibly so. Climate variability has at times created new niches that humans or their ancestors could potentially exploit, and challenges that at times have spurred innovation. But there’s a relatively narrow envelope of climate variability within which human civilization remains viable. And our survival depends on conditions remaining within that range. In this book, renowned climate scientist Michael Mann will arm listeners with the knowledge necessary to appreciate the gravity of the unfolding climate crisis.

As new climate disasters remind us every day, our world is not stable—and it is changing in ways that expose the deep dysfunction of our relationship with water. But as we grapple with extreme weather, a hard truth is emerging: our development, including concrete infrastructure designed to control water, is actually exacerbating our problems. Because sooner or later, water always wins. In this quietly radical book, science journalist Erica Gies introduces us to innovators in what she calls the Slow Water movement who start by asking a revolutionary question: What does water want?

Spanning millennia and continents, here is a stunningly revealing history of how the distribution of water has shaped human civilization. Boccaletti, of The Nature Conservancy, “tackles the most important story of our time: our relationship with water in a world of looming scarcity” (Kelly...

Griffins, cyclopes, monsters, and giants - these fabulous creatures of classical mythology continue to live in the modern imagination through the vivid accounts that have come down to us from the ancient Greeks and Romans. But what if these beings were more than merely fictions? Through careful research and meticulous documentation, Adrienne Mayor convincingly shows that many of the giants and monsters of myth did have a basis in fact - in the enormous bones of long-extinct species that were once abundant in the lands of the Greeks and Romans.

Captain Guyan March had spent his entire professional career aboard Windjammer Barefoot Cruises’ fleet of extravagant tall ships that carry passengers on weeklong fantasy cruises spiced with rum and sun. When he agreed to command the Fantome, Windjammer’s marquee ship, a beautiful 282-foot schooner that “sailed like a pig” in the Gulf of Honduras, he knew that a storm would leave him little space to run. In the southern reaches of the Caribbean, Tropical Storm Mitch whirled to life like a nebula and became Captain March’s worst nightmare.

In Four Lost Cities, acclaimed science journalist Annalee Newitz takes listeners on an entertaining and mind-bending adventure into the deep history of urban life. Investigating across the centuries and around the world, Newitz explores the rise and fall of four ancient cities, each the center of a sophisticated civilization: the Neolithic site of Çatalhöyük in Central Turkey, the Roman vacation town of Pompeii in Italy, the medieval megacity of Angkor in Cambodia, and the indigenous metropolis Cahokia, which stood beside the Mississippi River where East St. Louis is today.

As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.
