Condition: 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. Condition: 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.…
