Around 13,000 years ago, three things happened at once: (1) Global temperature suddenly stopped rising and plunged back to ice age-frigidity. (2) The Western Hemisphere’s largest mammals, including the horse, camel, woolly mammoth, saber-toothed cat, and dozens more, went extinct. And (3) the uniquely beautiful stonework of the early American Clovis people disappeared from the archeological record. For the past half-century, scientists have struggled to explain the three events. Were they independent of each other, or could they have had a common cause?

From late 1872 to 1876, H.M.S. Challenger explored the world's oceans. Conducting deep sea soundings, dredging the ocean floor, recording temperatures, observing weather, and collecting biological samples, the expedition laid the foundations for modern oceanography. Following the ship's naturalists and their discoveries, earth scientist Doug Macdougall engagingly tells a story of Victorian-era adventure and ties these early explorations to the growth of modern scientific fields.

Nick Bullock is a climber who lives in a small, green van, flitting between Llanberis, Wales, and Chamonix in the French Alps. Tides, Nick’s second work, is the much-anticipated follow-up to his critically acclaimed debut, Echoes. Tides is a gripping memoir that captures the very essence of what it means to dedicate one’s life to climbing.

Journalist and broadcaster Alok Jha talks to leading explorers, scientists, conservationists and artists about Antarctica’s fascinating past, present and future, to discover why the icy continent matters to us all.Created by the UK Antarctic Heritage Trust to celebrate the 200th anniversary of the first sighting of Antarctica. UKAHT is a charity, championing the public understanding of, and engagement with Antarctica through the history of human endeavour in the region. UKAHT looks after British historic sites and artefacts in Antarctica and invests in global public programmes and ...

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.

Joe Tasker lies, struck down by illness, in a damp, bug-infested room in the Himalaya, wondering if he will be well enough to climb Dunagiri, his first venture to the "big" mountains. One of Britain’s foremost mountaineers and a pioneer of lightweight climbing, he is about to attempt one of the first true "Alpine-style" climbs in the Greater Ranges. The Dunagiri attempt forms part of Tasker’s striking tale of adventure in the savage arena of the mountains.

Patagonia. The name connotes the exotic and a distance that seems nearly mythical. Tucked toward the toe of South America, this largely unsettled landscape is among the most varied and breathtaking in the world - aching in its beauty as it sweeps from the Andes through broad, arid steppes to pristine beaches and down to a famously violent sea. It is also home to a vast array of rare wildlife as diverse and fascinating as the region itself.

Wheeler is Britain's foremost woman travel writer. Glowing Still is the story of her travelling life - what is 'important, revealing or funny' - in a notoriously testosterone-laden field. Growing up among blue-collar Conservatives in Bristol where 'we didn't know anyone who wasn't like us', Wheeler knew she needed to get away. In her twenties she began a dramatic escape: Pole to Pole, via Poland. Glowing Still recalls happy days on India's Puri Express; an Antarctic lavatory through which a seal popped up (hot fishy breath!); and the louche life of a Parisian shopgirl.

Humankind has explored every continent on earth, climbed its tallest mountains, and gone into space. But the largest areas of our planet remain a mystery: the deep oceans. At over 36,000 feet deep, these areas closest to earth’s core have remained nearly impossible to reach - until now. Technological innovations, engineering breakthroughs and the derring-do of a unique team of engineers and scientists, led by explorer Victor Vescovo, brought together an audacious global quest to dive to the deepest points of all five oceans for the first time in history.

Antarctica, the ice kingdom hosting the South Pole, looms large in the human imagination. The secrets of this vast frozen desert have long tempted explorers, but its brutal climate and glacial shores notoriously resist human intrusion. Land of Wondrous Cold tells a gripping story of the pioneering 19th-century voyages, when British, French, and American commanders raced to penetrate Antarctica’s glacial rim for unknown lands beyond. These intrepid Victorian explorers laid the foundation for our current understanding of Terra Australis Incognita.

On 30 January, 1981 Joe Tasker and Ade Burgess stood at 24,000 feet on the west ridge of Mount Everest. Below them were their companions, some exhausted, some crippled by illness, all virtually incapacitated. Further progress seemed impossible. Everest the Cruel Way is Joe Tasker's story of an attempt to climb the highest mountain on earth - an attempt which pushed a group of Britain's finest mountaineers to their limits. The goal had been to climb Mount Everest at its hardest: via the infamous west ridge, without supplementary oxygen and in winter.

In the summer of 2012, a team of six climbers set out to attempt the first ascent of one of the great unclimbed lines of the Himalaya - the giant Mazeno Ridge on Nanga Parbat, the world's ninth highest mountain. At 10 kilometers in length, the Mazeno is the longest route to the summit of an 8,000-meter peak. Ten expeditions had tried and failed to climb this enormous ridge.

On the afternoon of July 13, 1977, having become the first climbers to reach the summit of the Ogre, Doug Scott and Chris Bonington began their long descent. In the minutes that followed, any feeling of success from their achievement would be overwhelmed by the start of a desperate fight for survival. And things would only get worse.

Netting the Sun offers a carefully crafted diversity of natural and human stories from a landscape seemingly empty and forlorn to passing casual travelers. This surprising interpretation of south central Oregon's botany, geology, wildlife, ethnography, and history reveals what a truly special place the high desert is.

In this poetic personal narrative, Thomas P. Huber reflects on two seemingly unrelated places—the North Fork Valley in western Colorado and the Coulon River Valley in Provence, France—and finds a shared landscape and sense of place. What began as a simple comparison of two like places in distant locations turned into a more complex, interesting, and personal task. Much is similar: the light, the valleys, the climate, the agriculture. And much is less so: the history, the geology, the physical makeup of villages.
