There have been many books about Antarctica in the past, but all have focused on only one aspect of the continent - its science, its wildlife, the heroic age of exploration, personal experiences or the sheer awesome beauty of the landscape- but none have managed to capture the whole story, until now. Gabrielle Walker, author, consultant to New Scientist and regular broadcaster with the BBC has written a book unlike any that has ever been written about the continent. Antarctica weaves all the significant threads into an intricate tapestry, made up of science, natural history, poetry, epic history, what it feels like to be there and why it draws so many different kinds of people back there again and again. It is only when all the parts come together that the underlying truths of the continent emerge. Antarctica is the most alien place on Earth, the only part of our planet where humans could never survive unaided. It is truly like walking on another planet. And yet, in its silence, its agelessness and its mysteries lie the secrets of our past, and of our future.

We don't just live in the air; we live because of it. It's the most miraculous substance on earth, responsible for our food, our weather, our water, and our ability to hear. In this exuberant book, gifted science writer Gabrielle Walker peels back the layers of our atmosphere with the stories of the people who uncovered its secrets:
- A flamboyant Renaissance Italian discovers how heavy our air really is: The air filling Carnegie Hall, for example, weighs seventy thousand pounds.
- A one-eyed barnstorming pilot finds a set of winds that constantly blow five miles above our heads.
- An impoverished American farmer figures out why hurricanes move in a circle by carving equations with his pitchfork on a barn door.
- A well-meaning inventor nearly destroys the ozone layer.
- A reclusive mathematical genius predicts, thirty years before he's proved right, that the sky contains a layer of floating metal fed by the glowing tails of shooting stars.

Last year, awareness about global warming reached a tipping point. Now one of the most dynamic writers and one of the most respected scientists in the field of climate change offer the first concise guide to both the problems and the solutions. Guiding us past a blizzard of information and misinformation, Gabrielle Walker and Sir David King explain the science of warming, the most cutting-edge technological solutions from small to large, and the national and international politics that will affect our efforts.

While there have been many other books about the problem of global warming, none has addressed what we can and should do about it so clearly and persuasively, with no spin, no agenda, and no exaggeration. Neither Walker nor King is an activist or politician, and theirs is not a generic green call to arms. Instead they propose specific ideas to fix a very specific problem. Most important, they offer hope: This is a serious issue, perhaps the most serious that humanity has ever faced. But we can still do something about it. And they'll show us how.

¿Sucumbió la Tierra a una superglaciación, en la que todo el planeta, desde los polos al Ecuador, quedó cubierto de hielo? En Cataclismo climático, la escritora Gabrielle Walker ha creado una historia de aventuras e intriga a escala global, siguiendo los pasos del brillante científico Paul Hoffman y de un elenco de intrépidos geólogos en su batida por el planeta. De ese modo, descubre una pista sorprendente tras otra y pretende demostrar que hace setecientos millones de años la Tierra se congeló por completo y se convirtió en una gigantesca «bola de nieve» en el transcurso de la peor catástrofe climática de la historia.Lejos de acabar con la vida en la Tierra, este proceso de ultracongelación global fue el desencadenante de la explosión cámbrica, ese momento en la historia de nuestro planeta en que emergieron las formas de vida actuales.

We not only live in the air, we live because of it. At ground level air transforms miraculously; it wraps our planet in a blanket of warmth, while the outer layer of our atmosphere soaks up violent flares from the sun. In this fascinating celebration of the Earth's fragile atmosphere, Gabrielle Walker traces a journey of groundbreaking scientific discovery from the first experiments in the Renaissance to recent findings in space.
