Six Degrees: Our Future on a Hotter Planet
Adult/High School—Lynas has gathered global-warming information from an array of authoritative scientists: geologists, glaciologists, oceanographers, climate scientists, and paleoclimatologists, as well as "major scientific projections" from computer modelers. He divides his findings into six main chapters representing the consequences of a one- to six-degree shift in temperature rise. More factual than hysterical and using accessible language, the author portrays a sobering, but broad and fascinating, view of the problem. He discusses not only the environmental consequences of melting icecaps, ocean warming, coral reef bleaching, CO2 emissions, deforestation, and severe weather, but also cultural and economic reverberations-the result of population shifts, animal migrations, and societal collapse. Through computer-modeling simulations he looks back into the past (the Pliocene, the Mayan civilization) and projects into the future for CO2 comparisons. His premise: the problem is now at global scale and will not just impact the disappearance of one group alone as it did the Maya. Claiming that solutions must be political, and that it is too late for quick fixes using renewable energy sources or technology, he concludes with some cautionary possible solutions: relocalization of goods and services, less consumption, global-scale carbon rationing, and a "2 degree increase target." Anyone studying climate change will find this a helpful reference as much current research has been precompiled and interpreted within one resource.—Jodi Mitchell, Berkeley Public Library, CACopyright © Reed Business Information, a division of Reed Elsevier Inc.
