The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

The great unknown of the Southwest is conquered by a one-armed man and his crew of adventurers, placing the Colorado River and the Grand Canyon on the map of the American continent. It is a journey no human being had ever made before. Dangerous rapids, narrow canyon walls offering no escape, terrifying river waterfalls, capsized boats, near drowning, lost equipment and disillusioned men are dramatically described by John Wesley Powell, leader of this adventurous party.

Earth, from space, looks like a shimmering gem suspended in an inky, infinite expanse. But this serene image masks the magnificent and volatile interior forces that make life possible for millions of species on the surface. The placid appearances of our neighboring planets similarly belie their powers—and science fiction-worthy features, like diamond rain.

A weekly podcast sharing stories of the amazing people and projects that make up the fisheries science profession.

Learn the science behind weather and weather prediction in this clear and straightforward new guide. Weather is everywhere, and while it's typically not thought about most of the time, it can get everyone's attention in an instant - whether it's the swirling destruction of a tornado, the wreckage from a hurricane, or the havoc of climate change on the environment.

Mars, the red planet, is ingrained in our culture, from David Bowie's extra-terrestrial spiders to Captain Scarlet to War of the Worlds. It has inspired hundreds of authors, scientists and science-fiction writers - but why? What is it about this particular planet that makes it so intriguing? Ancient mythologies defined Mars as a violent harbinger of war, star-gazers puzzled over its peculiar motion, and astrologers defined human personalities by its position and bizarre dance through the sky.

What’s in a cloud? Did you know that water vapor is invisible and actually lighter than dry air? What separates a tropical storm from a winter blizzard? And what exactly is El Niño? Elliot Rappaport, a professional captain of traditional sailing ships, has spent three decades at sea, where understanding weather is crucial to the safety of vessels and their crews. In Reading the Glass, he offers a sailor’s-eye view of the moving parts of our atmosphere and unveils the larger patterns it holds: global winds, storms, air masses, jet streams, and the longer arc of our climate.

When the writer Donovan Hohn heard of the mysterious loss of thousands of bath toys at sea, he figured he would interview a few oceanographers, talk to a few beachcombers, and read up on Arctic science and geography. But questions can be like ocean currents: wade in too far, and they carry you away. Hohn's accidental odyssey pulls him into the secretive world of shipping conglomerates, the daring work of Arctic researchers, the lunatic risks of maverick sailors, and the shadowy world of Chinese toy factories.

A series of glasses of transparent liquids is in front of you: but which will quench your thirst and which will kill you? And why? Why does one liquid make us drunk and another power a jumbo jet? Sometimes dangerous, often delightful and always fascinating, discover the secret lives of liquids, from one of our best known scientists. From the best-selling author of Stuff Matters comes a fascinating tour of the world of these surprising or sinister substances - the droplets, heartbeats and ocean waves we encounter day to day.

Cutting-edge techniques across biology, chemistry, physics, and geology have transformed our understanding of the deep past, including the discovery of a previously unknown mass extinction. This compelling evidence, revealing a series of environmental crises resulting in the near collapse of life on Earth, illuminates our current dilemmas in exquisite detail.

1816 was a remarkable year - mostly for the fact that there was no summer. As a result of a volcanic eruption at Mount Tambora in Indonesia, weather patterns were disrupted worldwide for months, allowing for excessive rain, frost, and snowfall through much of the Northeastern US and Europe in the summer of 1816.

The Greening Defence podcast investigates the ways in which the UK defence sector is working to respond to the challenges and evolving security risks from the effects of climate change. In collaboration with our partners at the Conflict and Environment Observatory, this RUSI podcast brings together key figures from across defence, industry and academia to discuss how the various military sectors are approaching the issue, how policy is evolving, whether technology might hold the answer, and what cultural changes are required to ensure success. While some changes will be dramatic, others will ...

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.

Taking listeners from the melting Alaskan permafrost to storm-torn New Orleans, acclaimed journalist Elizabeth Kolbert approaches this monumental problem from every angle. She interviews researchers and environmentalists, explains the science, draws frightening parallels to lost civilizations, and presents the moving tales of people who are watching their worlds disappear.

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.

In late September 2015, Hurricane Joaquin swept past the Bahamas and swallowed a pair of cargo vessels in its destructive path: El Faro, a 790-foot American behemoth with a crew of 33, and the Minouche, a 230-foot freighter with a dozen sailors aboard. From the parallel stories of these ships and their final journeys, Tristram Korten weaves a remarkable tale of two veteran sea captains from very different worlds, the harrowing ordeals of their desperate crews, and the Coast Guard’s extraordinary battle against a storm that defied prediction.

A sweeping, interdisciplinary history of the world's third-largest river, a potent symbol across South Asia and the Hindu diaspora. Weaving together geography, environmental politics, and religious history, Sen offers a remarkable portrait of one of the world's largest and most densely populated river basins.

How did the dog become man’s best friend? A celebrated anthropologist unearths the mysterious origins of the unique partnership that rewrote the history of both species.

Spanning millennia and continents, here is a stunningly revealing history of how the distribution of water has shaped human civilization. Giulio Boc­caletti - honorary research associate at the Smith School of Enterprise and the Environment, Univer­sity of Oxford - shrewdly combines environmental and social history, beginning with the earliest civ­ilizations of sedentary farmers on the banks of the Nile, the Tigris, and the Euphrates Rivers.
