Every minute, several huge “snowballs” break up as they approach the Earth and deposit a large cloud of water vapor in Earth’s upper atmosphere. That’s the startling finding that world-renowned physicist Louis A. Frank came to after studying the images from the Dynamics Explorer 1 spacecraft. His conclusion, based on data acquired at the limits of detection, created a storm of controversy among scientists. This is the story that was told in The Big Splash, published in 1990. But, the story does not end there.

Sempre intenti a "riveder le stelle", per citare il Sommo Poeta, ma ci siamo mai interessati veramente a quanto accade invece sotto i nostri piedi? La risposta è sì, ovviamente, ed è proprio quello che fanno i geologi: studiano la Terra! Eppure, in chi non la conosce, la geologia è una scienza che evoca spesso, e ingiustamente, un sapore stantio. Un luogo comune che il nostro geologo preferito, Andrea Moccia, autore del progetto divulgativo "Geopop", si è proposto di sfatare in questo libro.

More than half a billion years ago, our world was completely covered by glaciers, a "Snowball Earth" that persisted for millions of years. Incredibly, this unimaginable cold led to the remarkable diversification of life on earth known as the Cambrian explosion. With a geologist's eye and a knack for storytelling, Graham Shields explores when and how such inhospitable conditions enabled animals to evolve, radiate, and diversify into our earliest ancestors.

Ob Landwirtschaft, Handel, Verkehr oder Urbanisierung: Seit es uns Menschen gibt, haben wir die Erde geprägt und verändert. Insbesondere seit der Industrialisierung hinterlassen wir einen unverwechselbaren und größtenteils unwiderruflichen Fingerabdruck auf der Erde. Inzwischen ist dieser Abdruck so stark, dass Wissenschaft, Politik und Gesellschaft diskutieren, ob sich die vom Menschen verursachten Veränderungen in geologischer Form niederschlagen und so langfristig sind, dass wir bereits in einem neuen Erdzeitalter leben – dem Anthropozän.

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. 

Para Lewis Dartnell la única manera de comprender nuestra historia consiste en explicar cómo nuestro planeta, desde el inicio de los tiempos, ha determinado nuestro destino. Toda especie está condicionada por su entorno.

Travelling a thousand miles and across three billion years, Christopher Somerville (walking correspondent of The Times and author of Coast, The January Man and Ships of Heaven) sets out to interrogate the land beneath our feet, and how it has affected every aspect of human history from farming to house construction, the Industrial Revolution to the current climate crisis. In his thousand-mile journey, Somerville follows the story of Britain's unique geology, travelling from the three-billion-year-old rocks of the Isle of Lewis, to the furthest corner of Essex.

Four-and-a-half billion years ago, Planet Earth was formed from a vast spinning nebula of cosmic dust, the detritus left over from the birth of the sun. Within the next 100 years, human life on swathes of the Earth's surface will end in a haze of heat, drought, and, again, dust. Dust is a legacy of 20th-century progress and a profound threat to life in the 21st century. And yet dust is something we hardly ever consider--it is so small and so mundane as to be beyond the threshold of thought. Jay Owen's Dust sparks curiosity and corrects that oversight.

World-renowned volcanologist Clive Oppenheimer has worked at the crater's edge in the wildest places on Earth. He's faced down AK47s, learned from tribal elders, and watched red hot rocks shoot into the sky. More people have been into space than have set eyes on the fiery depths of Mount Erebus in Antarctica, where he has measured the Earth's powerful forces. In Mountains of Fire, he paints volcanoes as otherworldly, magical places where our history is laid bare, and shows us just how entangled volcanic activity is with our climate, economy, politics, culture and beliefs.

Stone walls tell nothing less than the story of how New England was formed, and in Robert Thorson's hands they live and breathe. Millions of years ago, New England's stones belonged to ancient mountains thrust up by prehistoric collisions between continents. Buried again over centuries by forest and soil buildup, the stones gradually worked their way back to the surface, only to become impediments to the farmers cultivating the land in the eighteenth century, who piled them into "linear landfills," a place to hold the stones.

Lapidarium weaves the surprising stories of the 60 most fascinating stones into a rich cultural history: from the red ground hematite pigment our cave-painting ancestors used and the mystery behind the tuff Easter Island heads, to the columbite that caused the Playstation War and the intriguing history of the cairngorm crystal ball, to the scandalous story of Flint Jack, whose forgeries still populate many museums in the UK today.

Four geologists and two mountain guides face the brutal beauty of West Antarctica eight hundred miles from the United States main base. Their search reaches far into the treacherous mountains of Marie Byrd Land. Over six weeks of living in tents and traveling by snowmobile, the team endures endless cold and furious blizzards. They cross ice fields and hidden crevasses, which one of the team learns about the hard way.

To many of us, the Earth's crust is a relic of ancient, unknowable history. But to a geologist, stones are richly illustrated narratives, telling gothic tales of cataclysm and reincarnation. For more than four billion years, in beach sand, granite, and garnet schists, the planet has kept a rich and idiosyncratic journal of its past. Fulbright Scholar Marcia Bjornerud takes the listener along on an eye-opening tour of Deep Time, explaining in elegant prose what we see and feel beneath our feet.

Geology meets treasure hunting with this field guide to rockhounding! If you've ever kept an interesting rock or shell, bought a polished stone from a gift shop, or even just enjoyed a 'gram of a really cool crystal, congratulations! You've already experienced a rockhounding adventure!

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.
