Shall we take an umbrella... or evacuate the city? The Weather Machine is about a miraculous-but-overlooked invention that helps us through our daily lives - and sometimes saves them - by allowing us to see into the future.

When Superstorm Sandy hit North America, weather scientists had predicted its arrival a full eight days beforehand, saving countless lives and astonishing us with their capability. Their skill is unprecedented in human history and draws on nearly every major invention of the last two centuries: Newtonian physics, telecommunications, spaceflight and super-computing.

In this gripping investigation, Andrew Blum takes us on a global journey to explain this awe-inspiring feat - from satellites circling the Earth, to weather stations far out in the ocean, through some of the most ingenious minds and advanced algorithms at work today. Our destination: the simulated models they have constructed of our planet, which spin faster than time, turning chaos into prediction, offering glimpses of our future with eery precision.

This collaborative invention spans the Earth and relies on continuous co-operation between all nations - a triumph of human ingenuity and diplomacy we too often shrug off as a tool for choosing the right footwear each morning. But in this new era of extreme weather, we may come to rely on its maintenance and survival for our own.

In general, lives of noteworthy accomplishment are led by people with an obvious talent, or more than one. Occasionally, though, someone with no discernible gift whatsoever may distinguish him or herself with a remarkable life. Such cases invite the question of how? How did it happen? With age I have realised that mine is such a life, and, inevitably, I have asked that question. It may happen in cases like this that, as one searches for an answer, one looks for precedents: or even for gifts not inherent in oneself but from outside. I did neither: it came to me unbidden. As I sang, the lines in the hymn resonated so powerfully I could not get away from them: ‘As noiseless let Thy blessings fall as fell Thy manna down.’ That was it. Unobtrusively I had been blessed – again and again and again.

A dozy, unsocialised child follows a boringly ordinary course through life until gradually things start to work out for him in increasingly extraordinary ways. The only prize I ever won at school was the Natural History Prize, no academic accolades or colours for any sport. I was rewarded for loving undemanding nature; almost a non-prize. Nearly fifty years later, in a small town I had never visited before I was introduced to the author of a slim volume on the geography of the area. “Not THE Nick Norman,” she asked. I might have blushed. In 1987, aged 42 I had married, and gone on to father two children, one now a top lawyer, the other on a similar trajectory in medicine. Having dreamt of being a farmer, I owned a farm in Franschhoek, which put me in about the most envied group of people in South Africa. After a successful career in mineral exploration in Africa and South America I turned my hand to writing about geology in a way accessible to lay readers. Three best-sellers followed. The Red Sea opened up and the River Jordan stopped flowing, for the Israelites to reach their land of milk and honey. In between, though, there were 40 years in the wilderness.

This is my narrative. Yours will be different. Unpack it and you will find blessing after blessing. See how I found mine.

Adventures in Volcanoland charts journeys across deserts, through jungles and up ice caps, to some of the world's most important volcanoes, from Nicaragua to Hawaii, Santorini to Ethiopia, exploring Tamsin Mather's obsession with these momentous geological formations, the cultural and religious roles they have played in the minds of those living around them at different times throughout history, and the science behind their formation and eruptions.

Volcanoes help to make and shape our world, bursting forth from inside of the earth and, in many places, looming over us. Present since the earth's beginning they continue to maintain its life support systems and, their extraordinary chemistry may even have created the ingredients needed for life to kick start.

In some places volcanoes are even beginning to provide us with part of the energy we need to curb our use of fossil fuels. They have fascinated humans for millennia, their eruptions charted throughout history, seeming to show us how the earth has been living, breathing and changing for billions of years.

Why exactly are these geological mammoths found where they are? What can they teach us about our environment, the Anthropocene and the ecological disaster that is climate change? Are there volcanoes on other planets, and what might they tell us about whether we could one day live there if we exhaust our own habitat? How can we predict if or when volcanoes might explode?

Adventures in Volcanoland is an enthralling mix of travel, science and environmental writing for fans of Robert MacFarlane and Raynor Winn.

Rivers are significant geomorphological agents, they show an amazing diversity of form and behaviour and transfer water and sediment from the land surface to the oceans. This book examines how river systems respond to environmental change and why this understanding is needed for successful river management. Highly dynamic in nature, river channels adjust and evolve over timescales that range from hours to tens of thousands of years or more, and are found in a wide range of environments. This book provides a comprehensive overview of recent developments in river channel management, clearly illustrating why an understanding of fluvial geomorphology is vital in channel preservation, environmentally sensitive design and the restoration of degraded river channels. It covers: flow and sediment regimes: flow generation; flow regimes; sediment sources, transfer and yield channel processes: flow characteristics; processes of erosion and sediment transport; interactions between flow and the channel boundary; deposition channel form and behaviour: controls on channel form; channel adjustments; floodplain development; form and behaviour of alluvial and bedrock channels response to change: how channels have responded to past environmental change; impacts of human activity; reconstructing past changes river management: the fluvial hydrosystem; environmental degradation; environmentally sensitive engineering techniques; river restoration; the role of the fluvial geomorphologist. Fundamentals of Fluvial Geomorphology is an indispensable text for undergraduate students. It provides straightforward explanations for important concepts and mathematical formulae, backed up with conceptual diagrams and appropriate examples from around the world to show what they actually mean and why they are important. A colour plate section also shows spectacular examples of fluvial diversity.

The Elizabeth River courses through the heart of Virginia. The Jamestown colonists recognized the river's strategic importance and explored its watershed almost immediately after the 1607 founding. The Elizabeth River traces four centuries of this historic stream's path through the geography and culture of Virginia.

European explorers were captivated by the seemingly endless bounty of natural resources on Cape Cod Bay. One Englishman declared that the codfish were so thick one "could" walk on their backs. Early settlers quickly learned how to harness the bay's resources and excelled at shore whaling, shipping and salt making. But as these new industries flourished, the native Wampanoag, who helped the fledgling colony to take root, nearly vanished. Author Theresa Mitchell Barbo's skillful narrative weaves together the natural and cultural histories of the bay, highlighting some of the region's diverse milestones- from the drafting of the Mayflower Compact in 1620 to the establishment of the Pilgrim Nuclear Power Plant 350 years later. "Cape Cod Bay: A History of Salt & Sea" inspires new appreciation for this storied and stunning seascape, and underscores the importance of new efforts to preserve the bay's unique ecosystem.

Sand, salt, iron, copper, oil and lithium. They built our world, and they will transform our future.

These are the six most crucial substances in human history. They took us from the Dark Ages to the present day. They power our computers and phones, build our homes and offices, and create life-saving medicines. But most of us take them completely for granted.

In Material World, Ed Conway travels the globe - from the sweltering depths of the deepest mine in Europe, to spotless silicon chip factories in Taiwan, to the eerie green pools where lithium originates - to uncover a secret world we rarely see. Revealing the true marvel of these substances, he follows the mind-boggling journeys, miraculous processes and little-known companies that turn the raw materials we all need into products of astonishing complexity.

As we wrestle with climate change, energy crises and the threat of new global conflict, Conway shows why these substances matter more than ever before, and how the hidden battle to control them will shape our geopolitical future. This is the story of civilisation - our ambitions and glory, innovations and appetites - from a new perspective: literally from the ground up.

An unprecedented look inside the global battle to power our lives from acclaimed Reuters reporter Ernest Scheyder.

A new economic war for critical minerals has begun, and The War Below is an urgent dispatch from its front lines. To build electric vehicles, solar panels, cell phones, and millions of other devices means the world must dig more mines to extract lithium, copper, and other vital building blocks. But mines are deeply unpopular, even as they have a role to play in fighting climate change and powering crucial technologies. These tensions have sparked a worldwide reckoning over the sourcing of necessary materials, and no one understands the complexities of these issues better than Ernest Scheyder, whose exclusive access to sites around the globe has allowed him to gain unparalleled insights into a future without fossil fuels.

The War Below reveals the explosive brawl among industry titans, conservationists, community groups, policymakers, and many others over whether some places are too special to mine or whether the habitats of rare plants, sensitive ecosystems, Indigenous holy sites, and other places should be dug up for their riches.

With vivid and engaging writing, Scheyder shows the human toll of this war and explains why recycling and other newer technologies have struggled to gain widespread use. He also expertly chronicles Washington’s attempts to wean itself off supplies from China, the global leader in mineral production and processing. The War Below paints a powerfully honest and nuanced picture of what is at stake in this new fight for energy independence, revealing how America and the rest of the world’s hunt for the “new oil” directly affects us all.
