The big media have spoken on the question of global warming, and the debate is officially over. "Be afraid, be very afraid", warns Time magazine. But have Al Gore and his environmentalist allies really proven their case? Not even close, says Christopher C. Horner.

A volergli credere Esumim avrebbe partecipato a tutte le grandi migrazioni dell'umanità: "ci siamo divertiti - ripete sempre - non si stava mai fermi!". È l'immaginario testimone di un viaggio iniziato sei milioni di anni fa, il cui primo passo - quello di scendere dagli alberi - ha dato avvio alla lunga catena di migrazioni attraverso la quale i nostri antenati hanno colonizzato il pianeta. Quante umanità diverse - dagli Austrolopiteci a Neandertal, a Homo sapiens - si sono succedute e incrociate sulla Terra?

When leading Princeton physicist Paul Steinhardt began working in the 1980s, scientists thought they knew all the conceivable forms of matter. The Second Kind of Impossible is the story of Steinhardt’s 35-year-long quest to challenge conventional wisdom. It begins with a curious geometric pattern that inspires two theoretical physicists to propose a radically new type of matter - one that raises the possibility of new materials with never-before-seen properties but that violates laws set in stone for centuries.

We live at the bottom of an ocean of air - 5,200 million million tons, to be exact. It sounds like a lot, but Earth’s atmosphere is smeared onto its surface in an alarmingly thin layer - 99 percent contained within 18 miles. Yet, within this fragile margin lies a magnificent realm - at once gorgeous, terrifying, capricious, and elusive. With his keen eye for identifying and uniting seemingly unrelated events, Chris Dewdney reveals to us the invisible rivers in the sky that affect how our weather works and the structure of clouds and storms and seasons, the rollercoaster of climate.

Siamo abituati a concepire la Storia come il susseguirsi sanguinoso di imperi e dinastie. Ma il cammino dell'uomo può essere studiato anche in ambiti specifici del suo ingegno - nell'arte, nella filosofia o nelle scienze. Questo audiolibro propone una chiave molto stimolante attraverso cui "ricapitolare" la storia dell'umanità: quella che vede l'essenza del nostro genere nell'"essere artefice". Perché, a pensarci bene, dietro ogni passo dell'uomo c'è sempre un'invenzione o un manufatto che ha avuto nei secoli imprevedibili sviluppi.

Following on from the success of 13 Journeys Through Space and Time, which took us on a voyage of astronomical discovery through past Christmas Lectures given at the Royal Institution on space and space exploration, this audiobook turns our attention to our own planet and the animals, plants, fish and insects and all the other living things that inhabit it - how they've evolved and the vital roles they play in the intricate webs of life on earth.

Here, political scientist Jakub J. Grygiel brings to light the importance of incorporating geography into grand strategy. He argues that states can increase and maintain their position of power by pursuing a geostrategy that focuses on control of resources and lines of communication.

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.

Although we usually think of technology as something unique to modern times, our ancestors began to create the first technologies millions of years ago in the form of prehistoric tools and weapons. Over time, eight key technologies gradually freed us from the limitations of our animal origins.

In the 1990s, researchers in the Arctic noticed that floating summer sea ice had begun receding. This was accompanied by shifts in ocean circulation and unexpected changes in weather patterns throughout the world. The Arctic's perennially frozen ground, known as permafrost, was warming, and treeless tundra was being overtaken by shrubs. What was going on? Brave New Arctic is Mark Serreze's riveting firsthand account of how scientists from around the globe came together to find answers.

Coursing through the Atlantic Ocean is a powerful current with a force 300 times that of the mighty Amazon. Ulanski explores the fascinating science and history of this sea highway known as the Gulf Stream, a watery wilderness that stretches from the Caribbean to the North Atlantic. Spanning both distance and time, Ulanski's investigation reveals how the Gulf Stream affects and is affected by every living thing that encounters it--from tiny planktonic organisms to giant bluefin tuna, from ancient mariners to big-game anglers.

On Shishmaref Island in Alaska, homes are being washed into the sea. In the South Pacific, small island nations face annihilation by encroaching waters. In coastal Louisiana, an area the size of a football field disappears every day. For these communities, sea level rise isn’t a distant, abstract fear: it’s happening now and it’s threatening their way of life. In The Rising Sea, Orrin H. Pilkey and Rob Young warn that many other coastal areas may be close behind.

In the middle of the Mojave Desert, Las Vegas casinos use billions of gallons of water for fountains, pirate lagoons, wave machines, and indoor canals. Meanwhile, the town of Orme, Tennessee, must truck in water from Alabama because it has literally run out.Robert Glennon captures the irony - and tragedy - of America’s water crisis in a book that is both frightening and wickedly comical.

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.

What's the connection between a platter of jumbo shrimp at your local restaurant and murdered fishermen in Honduras, impoverished women in Ecuador, and disastrous hurricanes along America's Gulf coast? Mangroves. Many people have never heard of these salt-water forests, but for those who depend on their riches, mangroves are indispensable. In Let Them Eat Shrimp, Kennedy Warne takes listeners into the muddy battle zone that is the mangrove forest.

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.

"Tutta la nostra scienza, in confronto con la realtà, è primitiva e infantile, e tuttavia è la cosa più preziosa che abbiamo". Albert Einstein. Massimo Polidoro, scrittore e divulgatore scientifico, ci conduce alla scoperta dei tanti modi in cui la scienza attraversa la nostra vita quotidiana, aiutandoci a capire quello che ognuno di noi dovrebbe conoscere.

Thirty thousand years ago our prehistoric ancestors painted perfect images of animals on walls of tortuous caves, most often without any light. How was this possible? Scholars and archaeologists have for centuries pored over these works of art, speculating and hoping to come away with the key to the mystery. David and Lefrre give us a new understanding of an art lost in time, revealing what had until recently remained unexplainable - the oldest enigma in humanity has been solved.

Ranging from prehistory to the 21st century, The Great Sea is above all the history of human interaction across a region that has brought together many of the great civilizations of antiquity as well as the rival empires of medieval and modern times.

When Indonesia's Mount Tambora erupted in 1815, it unleashed the most destructive wave of extreme weather the world has witnessed in thousands of years. The volcano's massive sulfate dust cloud enveloped the Earth, cooling temperatures and disrupting major weather systems for more than three years. Amid devastating storms, drought, and floods, communities worldwide endured famine, disease, and civil unrest on a catastrophic scale.
