Extinctions (Más de 1600 resultados)

Condición: Good. According to University of Washington paleontologist Peter D. Ward, all but one of the major extinction events in the history of the world have been brought on by climate change-the same global warming that occurs today. In Under a Green Sky, he examines the causes of the Permian extinction, an event more than 200 million years ago so cataclysmic that it destroyed more than 90% of all species and nearly 97% of all living things. This near-total devastation was caused by a warming of the earth due to rising levels of carbon dioxide. Ward explains how that extinction, as well as four others, happened, and then applies those chilling lessons to the present day, showing how the ancient past may hold the key to earth's future.…

Paperback. Condición: Good. More than 200 million years ago, a cataclysmic event known as the Permian extinction destroyed more than 90% of all species and nearly 97% of all living things. Its origins have long been a puzzle for paleontologists, and during the 1990s and the early part of this century a great battle was fought between those who thought that death had come from above and those who thought something more complicated was at work. Paleontologist Peter D. Ward, fresh from helping prove that an asteroid had killed the dinosaurs, turned to the Permian problem, and he has come to a stunning conclusion. In his investigations of the fates of several groups of mollusks during those extinctions and others, he discovered that the near-total devastation at the end of the Permian was caused by rising levels of carbon dioxide leading to climate change. But it's not the heat (nor the humidity) that's directly responsible for the extinctions, and the story of the discovery of what is responsible makes for an fascinating, globe-spanning adventure.…

Hardback. Condición: Good. ***WINNER OF THE 2017 MILES FRANKLIN LITERARY AWARD*** "He hated the word 'retirement', but not as much as he hated the word 'village', as if ageing made you a peasant or a fool." Herein lives the village idiot. Professor Frederick Lothian, retired engineer, world expert on concrete, and connoisseur of modernist design, has quarantined himself from life by moving to a retirement village. His wife, Martha, is dead and his two adult children are lost to him in their own ways. Surrounded and obstructed by the debris of his life-objects he has collected over many years and tells himself he is keeping for his daughter-he is determined to be miserable. When a series of unfortunate incidents forces him and his neighbour, Jan, together, he begins to realise the damage done by the accumulation of a lifetime's secrets and lies, and to comprehend his own shortcomings. Finally, Frederick Lothian has the opportunity to build something meaningful for the ones he loves. Humorous, poignant and galvanising by turns, Extinctions is a novel about all kinds of extinction-natural, racial, national, and personal-and what we can do to prevent them. [Subject: Fiction].…

Hardback. Condición: Very Good. The End of the Dinosaurs gives a detailed account of the great mass extinction that rocked the Earth 65 million years ago, and focuses on the discovery of the culprit: the Chicxulub impact crater in Mexico. It recounts the birth of the cosmic hypothesis, the controversy that preceded its acceptance, the search for the crater, its discovery and ongoing exploration, and the effect of the giant impact on the biosphere. Other mass extinctions in the fossil record are reviewed, as is the threat of asteroids and comets to our planet today. The account of the impact and its aftermath is suitable for general readers. The description of the crater geology is in enough detail to interest students of the earth sciences. A detailed index and bibliography are included.…

Hardback. Condición: Good. Two hundred sixty million years ago, life on Earth suffered wave after wave of cataclysmic extinctions, with the worst wiping out nearly every species on the planet. The Worst of Times delves into the mystery behind these extinctions and sheds light on the fateful role the primeval supercontinent, known as Pangea, might have played in causing these global catastrophes. Drawing on the latest discoveries as well as his own firsthand experiences conducting field expeditions to remote corners of the world, Paul Wignall reveals what scientists are only now beginning to understand about the most prolonged and calamitous period of environmental crisis in Earth's history. Wignall shows how these series of unprecedented extinction events swept across the planet, killing life on a scale more devastating than the dinosaur extinctions that would follow. The Worst of Times unravels one of the great enigmas of ancient Earth and shows how this ushered in a new age of vibrant and more resilient life on our planet.…
