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.

今、世界は新型コロナによって、グローバル・ボーダーレス化からローカル・ボーダー化に逆戻りしている。そんな変化の激しい現代社会を読み解くための強力なツール(教養)が「歴史」と「地理」。

Earth stands at a tipping point. As we fail to curtail emissions fast enough, our planet stares down a cascade of imminent, catastrophic, and irreversible disaster triggered by climate change. Yet a potent technology already exists to buy us more time: solar geoengineering. Through methods such as atmospheric aerosols, human-generated cirrus clouds, and solar sails, we humans can—at least in the short term—slow the Earth's warming. Should we?

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. For example, the current eon is called the Phanerozoic Eon, which means “visible life”. This is the eon in which multicellular life has evolved and thrived. Before this, life was microscopic (single cells).

Brought to you by Penguin. In 1979, President Jimmy Carter was presented with the findings of scientists who had been investigating whether human activities might change the climate in harmful ways. "A wait-and-see policy may mean waiting until it is too late," their report said. They were right...

The ugly truth about dams is about to be revealed. During the first two decades of the twenty-first century, the whole messy truth about the legacy of last century’s big dam building binge has come to light. What started out as an arguably good government project has drifted oceans away from...

Climate change has been a perplexing problem for years. Casey's research into the Sun's activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next 30 years or more. This new cold climate will dramatically impact the world's citizens.

Biogeography is the study of geographic variation in all characteristics of life - ranging from genetic, morphological, and behavioral variation among regional populations of a species, to geographic trends in diversity of entire communities across our planet's surface. From the ancient hunters and gatherers to the earliest naturalists, Charles Darwin, Alfred Russel Wallace, and scientists today, the search for patterns in life has provided insights that proved invaluable for understanding the natural world. 

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.

Otros mundos devuelve a la vida dieciséis ecosistemas de un pasado inimaginablemente remoto y nos muestra continentes en movimiento, arrecifes de cristal, hongos de tres metros de altura, pingüinos gigantes, reptiles emplumados y muchas otras criaturas asombrosas de un atractivo casi mitológico. A medida que viajamos hacia atrás en el tiempo, redescubrimos nuestro propio hogar de formas irreconocibles, y nos sobrecogen los ecosistemas que se transforman y los devastadores escenarios que han causado el fin de incontables especies.

Thank you for joining us on this journey to discover more about the English Riviera UNESCO Global Geopark, one of Earth’s Extraordinary Places. In this series of interviews, Geopark Patron Professor Iain Stewart explore what it is that makes this Geopark so special, from when the rocks around us were formed, to evidence of early humans and right up to artists and writers who are being inspired by the Geopark today.

There is one thing you will hear me say again and again. As long as someone else is in control of your resources, they are in fact in control of your life. Consequently, my solution to that problem was to develop a sustainable, self reliant lifestyle. Not only that, but I’ve lived off the grid for more than 20 years. This podcast is not only about sustainable living it is also about teaching you to take more control over your life by being in control of many of your resources. It is possible to live a life without debt, produce much of your own food, have much more personal freedom, as well ...

The Grand Canyon’s Secrets takes listeners on a journey through science, history, and myth to answer these questions. Moving beyond tourist brochures, this book explores the canyon as a geological archive, a cultural landmark, and a still-active natural laboratory.

By 2030, experts predict two-thirds of people living on this planet will not have enough water, a situation expected to result in the deaths of millions and an unprecedented rise in military conflicts. Can we as individuals hope to reverse these dire predictions? Award-winning author and water activist Florencia Ramirez believes we can if our conservation efforts focus on the 70 percent of freshwater flowing to the fields and ranches that grow our food. Eat Less Water takes the listener on a journey to meet America's food producers growing food with less water.

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.
