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.

Un'energia di origine antichissima, che meglio di altre rappresenta l'Italia: la geotermia è entrata infatti sulla scena mondiale con il piccolo centro toscano di Larderello, e dall'Italia, rimasta per decenni l'unico produttore, si è diffusa in altri paesi. Oggi però, mentre le tecnologie associate allo sfruttamento delle fonti energetiche rinnovabili più note e finanziate, come l'eolico e il solare, stanno rapidamente progredendo, la geotermia occupa ancora un ruolo di nicchia.

La concentrazione di anidride carbonica in atmosfera ha ormai superato la soglia di 400 parti per milione. Arretramento dei ghiacciai, scioglimento delle calotte polari, innalzamento del livello del mare, aumento degli eventi estremi sono imputabili al riscaldamento provocato da questo gas serra che è al centro di una complessa interazione fra uomo e clima. Dall'atmosfera agli oceani, alla biosfera, che cosa è accaduto al nostro pianeta? Quali strumenti abbiamo per contenere i rischi di questa nuova minaccia globale?

Capire l'oggi per creare il domani. Un percorso di trasformazione su tre livelli: spirituale, culturale e tecnico. L'Uomo si è ormai perso nella sua rincorsa feroce al progresso, tutti gli ambiti delle sue attività danno continui messaggi d'allarme. L'ecosistema terrestre e la vita dell'Uomo stesso non sono mai stati messi a rischio come in questi ultimi decenni di enorme sviluppo industriale ed economico.

Come limitare l'impatto dei consumi di energia sull'uomo e sull'ambiente, senza compromettere lo sviluppo economico? Un impiego delle fonti rinnovabili, e in particolare dell'energia solare, è ormai ritenuto necessario e possibile, anche in ampie proporzioni. Nel volume si discutono gli aspetti tecnologici ed economici dello sfruttamento dell'energia solare e si offre un quadro delle politiche nazionali e dell'Unione europea nel settore.

Un fenomeno iniziato poco più di 2 milioni e mezzo di anni fa che ha avuto un ruolo determinante nella formazione del paesaggio attuale e nella diffusione ed evoluzione degli organismi viventi: sono le oscillazioni climatiche - note come glaciazioni - che hanno caratterizzato l'era Quaternaria, lasciando numerose testimonianze anche nella nostra penisola. Ghiacciai, fiumi e vulcani, fossili di specie estinte come mammut e iene giganti, e infine la conformazione attuale delle nostre coste testimoniano infatti come l'Italia sia stata un crocevia di migrazioni, adattamenti ed evoluzioni.

In questo audiolibro esclusivo Simone Bedetti ti introduce al pensiero di un grande scienziato e filosofo della natura, il premio Nobel per la chimica Ilya Prigogine. Prigogine, tra gli iniziatori della scienza della complessità, noto per le sue teorie sulle strutture dissipative, i sistemi complessi e l'irreversibilità, ha proposto una nuova e radicale visione del mondo riformulando il secondo principio della termodinamica: ogni processo naturale è irreversibile e tende ad aumentare la sua entropia (e quella dell'ambiente in cui si trova).

Un breve saggio, chiaro e semplice, per comprendere le ragioni individuali, sociali e spirituali che ci portano a scegliere la via ecologica e il ritorno alla natura. Con la mente, l’anima e il cuore. A short essay, plain and simple, to understand the reasons that lead us to choose the ecological way. With the mind, the soul and the heart.

Author Michael Quetting shares the hilarious and moving true story of how he became a father to seven rambunctious goslings - and the surprising things he learned along the way. Starting right at the beginning, with the eggs, his journey takes him from the incubator all the way to the airstrip, where he must attempt to teach the geese to fly as part of an ambitious scientific research initiative for the Max Planck Institute for Ornithology, which tracks animal migrations around the world.

Part of John Muir's appeal to modern audiences is that he not only explored the American West and wrote about its beauties but also fought for their preservation. His successes dot the landscape and are evident in all the natural features that bear his name: forests, lakes, trails, and glaciers. Here collected are some of Muir's finest wilderness essays, ranging in subject matter from Alaska to Yellowstone, from Oregon to the High Sierra.

The world needs to change. We have unleashed an ecological mega-crisis which is threatening the future of life on Earth. The actions we take over the next decade are critical. They will determine the destiny of our descendants and the fate of our world. How Soon Is Now presents a compelling manifesto for personal and planetary change. It proposes a revolutionary new narrative for a unified social movement. Through global cooperation, we can face this collective threat ecologically, socially, politically and spiritually.

Lighthouses are striking totems of our relationship to the sea. For many, they encapsulate a romantic vision of solitary homes amongst the waves, but their original purpose is much more utilitarian than that. Still today we depend upon their guiding lights for the safe passage of ships. Nowhere is this truer than in the rock lighthouses of Great Britain and Ireland, a ring of 19 towers built between 1811-1905, so called because they were constructed on desolate rock formations in the middle of the sea, and made of granite to withstand the power of its waves.

Beginning with his interactions with Dr Salim Ali, the legendary ornithologist - who was also his grand-uncle - wildlife biologist Rauf Ali takes the listener on a journey through India’s natural history and the beginning of ecological studies in India. Rauf was one of the first Indians to complete a PhD in wildlife biology - he researched the social behaviour of bonnet macaques in the forests of Mundanthurai region in Tamil Nadu. In the late 1980s, he was instrumental in setting up one of India’s first master's programmes in ecology.

Following a year of record numbers of shark attacks, Sharks Never Sleep takes us around the world to meet shark-attack survivors, shark lovers and shark hunters, who tell us of the primal fear of being eaten alive by a wild animal, the unimaginable grief of losing a loved one and extraordinary stories of encounters with sharks.

In BOOM, prize-winning reporter Tony Horwitz takes a spirited road trip through the wild new frontier of energy in North America. His journey begins in subarctic Alberta, where thousands of miners labor in an industrial moonscape to extract the region's oil-rich tar sands. Horwitz then follows the route of the proposed Keystone XL Pipeline that may carry tar-sands oil from Canada across Montana, the Dakotas, and Nebraska en route to Gulf Coast refineries.

In 2015, an American hunter named Walter Palmer shot and killed a lion named Cecil. The lion was one of dozens slain each year in Zimbabwe, which legally licenses the hunting of big cats. But Cecil’s death sparked unprecedented global outrage, igniting thousands of media reports about the peculiar circumstances surrounding this hunt. At the center of the controversy was Dr. Andrew Loveridge, the zoologist who had studied Cecil for eight years. In Lion Hearted, Loveridge pieces together, for the first time, the fascinating life and murky details of this beloved lion’s slaying.

Insects walk on water, snakes slither, and fish swim. Animals move with astounding grace, speed, and versatility: how do they do it, and what can we learn from them? In How to Walk on Water and Climb up Walls, David Hu takes listeners on an accessible, wondrous journey into the world of animal motion. From basement labs at MIT to the rain forests of Panama, Hu shows how animals have adapted and evolved to traverse their environments, taking advantage of physical laws with results that are startling and ingenious.

A toxic ideology rules the world of extreme competition and individualism. It misrepresents human nature, destroying hope and common purpose. Only a positive vision can replace it, a new story that re-engages people in politics and lights a path to a better world. George Monbiot shows how new findings in psychology, neuroscience and evolutionary biology cast human nature in a radically different light: as the supreme altruists and cooperators.

Survive or Sink is a wake-up call in these environmentally troubled times, in tackling issues that threaten India and the planet. The book underscores the role that citizens, industry, civil society, media and the government need to play in collaboration with each other to address poor sanitation, water and pollution, thus improving human well-being and health and thereby also reducing the impact of climate change.

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.
