This Introduction audiobook explores emerging geological research and explains how new advances in the understanding of plate tectonics, seismology, and satellite imagery have enabled us to begin to see the Earth as it actually is: dynamic and ever-changing.

In this epochal book, Immanuel Velikovsky, one of the great scientists of modern times, puts the complete histories of our Earth and of humanity on a new basis. He presents the results of his 10-year-long interdisciplinary research in an easily understandable, even entertaining manner. In spite - or even because - of the disgraceful hostility provoked by his theories, this book keeps being of ardent topicality, which in the light of recent scientific research is even growing.

Where has our planet come from, and what lies beneath its surface? How have we come to understand its past and present environments, and what does its future look like? Thanks to scientists who study its rocks, fossils, and landscapes, we know that Earth history spans over four and a half billion years. But there is still much more to discover.

The open ocean, far from the shore and miles above the seafloor, is a vast and formidable habitat that is home to the most abundant life on our planet, from giant squid and jellyfish to anglerfish with bioluminescent lures that draw prey into their toothy mouths. Into the Great Wide Ocean takes listeners inside the peculiar world of the seagoing scientists who are providing tantalizing new insights into how the animals of the open ocean solve the problems of their existence.

Australopithecines, dinosaurs, trilobites - such fossils conjure up images of lost worlds filled with vanished organisms. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty.

Few of us have any conception of the enormous timescales in our planet's long history, and this narrow perspective underlies many of the environmental problems we are creating for ourselves. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.

How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

Sixty-six million years ago an asteroid as large as Mt. Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet. Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires. This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.

In Earth, a planetary scientist and a literary humanist explore what happens when we think of the Earth as an object viewable from space. As a “blue marble,” “a blue pale dot,” or, as Chaucer described it, “this litel spot of erthe,” the solitary orb is a challenge to scale and to human self-importance. Beautiful and self-contained, the Earth turns out to be far less knowable than it at first appears: its vast interior an inferno of incandescent and yet solid rock and a reservoir of water vaster than the ocean, a world within the world.

An icon of the environmental movement outlines a provocative approach for reclaiming our planet. According to Stewart Brand, a lifelong environmentalist who sees everything in terms of solvable design problems, three profound transformations are under way on Earth right now. Climate change is real and is pushing us toward managing the planet as a whole. Urbanization - half the world's population now lives in cities, and 80 percent will by midcentury - is altering humanity's land impact and wealth.

Despite their cultural influence, the grand narrative of the dinosaur story is rarely told. Most of us have heard of Stegosaurus and Tyrannosaurus, but these two dinosaurs lived more than eighty million years apart—a greater span of time than the entire post-T. rex history of the planet. Furthermore, we often know even less about the environments these animals lived in. The Shortest History of the Dinosaurs tells the full story, a 230-million-year epic of small beginnings, spectacular golden periods, and eventual global domination.

In this entertaining book, Donald R. Prothero explores the astonishing connections between climate and life through the ages, telling the remarkable stories of the scientists who made crucial discoveries. Journeying through the intertwined evolution of climate and life, he tackles questions such as: Why do we have phytoplankton to thank for the air we breathe? What kind of climate was necessary for the rise of the dinosaurs-or the mammals, their successors? When and how have climatic changes caused mass extinctions?

In this Very Short Introduction, William Lowrie describes the internal and external processes that affect the planet, as well as the principles and methods of geophysics used to investigate them. From analyses of Earth's deepest interior to measurements made from Earth-orbiting satellites, Lowrie shows how geophysical exploration is vitally important in the search for mineral resources and emphasizes our need to understand the history of our planet and the processes that govern its continuing evolution.

Welchen Plan zur Rettung der Meere hat eine Tiefseeforscherin nach 7000 Stunden unter Wasser? Bietet Gentechnik einen Ausweg, die Welt zu ernähren? Helfen Speere und Social Media gegen die Ausbeutung indigener Gebiete in Ecuador? Geschichten wie diese machen die GEO-Reporter und -Reporterinnen erfahrbar. Bei ihren Reisen in die entlegensten Winkel der Welt verknüpfen sie Abenteuer, Wissen und gesellschaftliche Themen miteinander. In packenden Reportagen berichten sie in diesem Podcast von gewagten Recherchen, dramatischen Situationen und berührenden Begegnungen.

In 2018, lumps of frozen soil, collected from the bottom of the world's first deep ice core and lost for decades, reappeared in Denmark. When geologist Paul Bierman and his team first melted a piece of this unique material, they were shocked to find perfectly preserved leaves, twigs, and moss. That observation led them to a startling discovery: Greenland's ice sheet had melted naturally before, about 400,000 years ago.

Humans depend on soil for 95 percent of global food production, yet let it erode at unsustainable rates. In the United States, China, and India, vast tracts of farmland will be barren of topsoil within this century. The combination of intensifying erosion caused by climate change and the increasing food needs of a growing world population is creating a desperate need for solutions to this crisis.

There's finally reason to hope. Climate change is the existential threat of our time, but incredible new advancements in science and engineering can allow us to avoid the worst repercussions of global warming as we work to reverse it over time. In Our Livable World, research specialist and author Marc Schaus leads listeners in an exploration of the newest and upcoming innovations in green technology poised to prevent the climate apocalypse - and usher in a sustainable, livable world.

Super Volcanoes revels in the incomparable power of volcanic eruptions past and present, Earth-bound and otherwise, and explores how these eruptions reveal secrets about the worlds to which they belong. Science journalist and volcanologist Robin George Andrews describes the stunning ways in which volcanoes can sculpt the sea, land, and sky, and even influence the machinery that makes or breaks the existence of life.

The science is overwhelming; the facts are in. The planet is heating up at an alarming rate and the results are everywhere to be seen. Yet, as time runs out, climate progress is blocked by the men who are profiting from the burning of the planet: energy moguls like the Koch brothers and Exxon Mobil CEO Rex Tillerson. Powerful politicians like Senators Mitch McConnell and Jim Inhofe, who receive massive contributions from the oil and coal industries. Most of these men are too intelligent to truly believe that climate change is not a growing crisis.
