Mr. Ward's other recent book, Out Of Thin Air, makes the case for changes in atmospheric chemistry being a major driver of evolution at the level of family and even order. This book recapitulates some of that hypothesis and the evidence to support it. I can hardly imagine that you will want to read one without wanting to read the other. This book is the friendlier to the non-scientist, made readable by an anecdotal science-adventure framework. In short, it's a pleasure to read... until you catch the spoor of Ward's dire predictions for our common future.Read more ›
Another extinction event, the Permian - Triassic (P-Tr), some 251 MYA, is informally known as 'the Great Dying.' Up to 96 percent of all marine species and 70 percent of terrestrial species were erased as global ecosystems crumbled. Life itself nearly died - and Peter Ward makes a compelling case in "Under a Green Sky: Global Warming, the Mass Extinctions of the Past, and What They Can Tell Us About Our Future" that global warming was the primary culprit.
The occurrence of mass extinction events is not open to debate - the data is in the strata - available to any researcher diligent enough to decode the physical evidence. Unlike some global warming books "Under a Green Sky" carefully examines the fossil and climate record to justify models and simulations designed to predict future events. Ward, a paleontology professor at the University of Washington, and a NASA staff astrobiologist, invokes runaway global warming as the primary driver of the P-Tr extinction - and convincingly demonstrates that an anthropogenic (human-caused) encore is the obscene outcome of business as usual energy policies.
"Under a Green Sky" recounts how scientists examine mass extinctions and determine plausible causes based on paleontological and geological evidence.Read more ›
It amazes me that there are still some people who deny that the process is occurring or that it is to a large extent human caused. Some go so far as to ascribe the whole idea to a secret plan to increase the use of nuclear power! But the evidence for global warming keeps piling up, despite their views. As a biologist I have observed the creep ahead of the seasons even in the temperate zone, and the Arctic is having an even more marked change. Numerous studies have linked the rise in temperature primarily to human carbon dioxide production.
Peter D. Ward is a professor of biology and earth and space sciences at the University of Washington in Seattle. While studying the mass extinctions of the past, especially the Permian-Triassic, the Triassic-Jurassic and the Paleocene-Eocene, he and his associates have turned up an even greater threat of global warming- the release of toxic gases from the oceans.
In "Under a Green Sky: Global Warming, the Mass Extinctions of the Past, and What they Can Tell Us About Our Future" Ward outlines the causes of these major extinctions. Once thought to all have occurred because of asteroid strikes, these extinctions were quite different from the Cretaceous-Paleocene event, which apparently was triggered by such a cosmic calamity.Read more ›
