From dinosaurs fighting to their deaths to elephant-sized burrowing ground sloths, this book takes listeners on a global journey deep into the earth's past. Locked in Time showcases fifty of the most astonishing fossils ever found, brought together in five fascinating chapters that offer an unprecedented glimpse at the real-life behaviors of prehistoric animals.

The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species-these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news.

The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. What humans commonly refer to as the “Ice Age” is actually a series of fluctuating climate events that have occurred throughout the planet’s history. These ongoing historical phenomena are difficult to conceptualize because of both the time frame involved and the natural process by which they cyclically unfold.

The rise of human civilization and all of recorded history occurred in this warm period, known as the Holocene. Until very recently, we had no detailed record of climate changes during the Holocene. Now we do. In this engrossing and captivating look at the human effects of climate variability, Brian Fagan shows how climate functioned as what the historian Paul Kennedy described as one of the “deeper transformations” of history—a more important historical factor than we understand.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.

In 1999, few people had thought to examine the effects of climate on civilization. Now, due in part to the groundbreaking work of archaeologist Brian Fagan, climate change is a central issue. Revised and updated 10 years after its first publication, Floods, Famines and Emperors remains the definitive account of how the world's best-known climate event had an indelible impact on history.

In late April 1902, Mount Pelee, a volcano on the Caribbean island Martinique, began to wake up. It emitted clouds of ash and smoke for two weeks until violently erupting on May 8. Over 30,000 residents of St. Pierre were killed; they burned to death under rivers of hot lava and suffocated under pounds of hot ash. Only three people managed to survive: a prisoner trapped in a dungeon-like jail cell, a man on the outskirts of town, and a young girl found floating unconscious in a boat days later.

With a tone that blends science, storytelling, and just the right amount of awe, author Serena Quillan dives deep into the biology, behaviour, and bizarre adaptations of this elusive cephalopod. This isn’t just another marine creature book—this is a guided expedition into a world most humans will never experience, revealing facts so surprising they’ll challenge what you think you know about life on Earth.

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.

Disaster relief as we know it did not exist when the deadliest tornado in U.S. history gouged a path from southeast Missouri through southern Illinois and into southwestern Indiana. The tri-state tornado of 1925 hugged the ground for 219 miles, generated wind speeds in excess of 300 miles per hour, and killed 695 people.

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.

In The Vanishing Earth, James Crawford, born into a landscape and family steeped in fossil fuels, takes listeners to the literal and ideological frontiers of extraction. Beginning with the story of humanity's decoupling from nature, Crawford embarks on an epic journey to five resource landscapes rapidly trending towards exhaustion: landscapes of rock, metal, sand, water and thought.

أنظمة الطاقة ضرورة من ضروريَّات الحياة في مجتمعاتنا المعاصرة. وتشمل أنظمة الطاقة استغلال الوقود الأولي، وتحويله، ونقله إلى نقاط الاستخدام. لكن هذا الوقود يكون في الكثير من الأحيان وقوداً أحفوريـاً؛ يُلحِق ضرراً جسيماً بالبيئة. ولهذا السبب صار تغيير أنظمة الطاقة الحالية أمراً حتميـاً إذا ما أردنا حماية كوكبنا. في هذا الكتاب، يأخذنا نِك جينكنز في رحلةٍ نستكشف خلالَها الجهود التي بذلها البشر في استغلال موارد الوقود الأحفوري. ويناقش الكتاب أيضاً آثار استخدامنا المتزايد للطاقة، والتغييرات الجذرية في تكنولوجيا الوقود، الضروريَّة لمواصلة توفير إمدادات الطاقة على نحو مستدام. ويناقش أيضاً تأثير التحوُّل إلى أنظمة طاقة منخفضة الانبعاثات الكربونية وصديقة للبيئة، قائمة على العديد من مصادر الطاقة المتجدِّدة المختلفة.

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.

The international bestselling author of The Professor and the Madman and Krakatoa vividly brings to life the 1906 San Francisco Earthquake that leveled a city symbolic of America's relentless western expansion. Simon Winchester has also fashioned an enthralling and informative informative look...

Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come - and takes a brilliantly educated guess at where we're heading.

The history of the Great Warming of a half millennium ago suggests that we may yet be underestimating the power of climate change to disrupt our lives todayand our vulnerability to drought, writes Fagan, is the silent elephant in the room.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

In December 1929, in a cave near Peking, a group of anthropologists and archaeologists that included a young French Jesuit priest named Pierre Teilhard de Chardin uncovered a prehuman skull. The find quickly became known around the world as Peking Man and was acclaimed as the missing link between erect hunting apes and our Cro-Magnon ancestors. It also became a provocative piece of evidence in the roiling debate over creationism versus evolution.

In movies, in novels, in comic strips, and on television, we've all seen dinosaurs - or at least somebody's educated guess of what they would look like. But what if it were possible to build, or grow, a real dinosaur without finding ancient DNA? Jack Horner, the scientist who advised Steven Spielberg on the blockbuster film Jurassic Park and a pioneer in bringing paleontology into the 21st century, teams up with the editor of the New York Times's Science Times section to reveal exactly what's in store.
