In Under a Green Sky, Ward explains how the Permian extinction as well as four others happened, and describes the freakish oceans--belching poisonous gas--and sky--slightly green and always hazy--that would have attended them. Those ancient upheavals demonstrate that the threat of climate change cannot be ignored, lest the world's life today--ourselves included--face the same dire fate that has overwhelmed our planet several times before.

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.
