It is unique among textbooks on climate change in that it combines an introduction of the science with an introduction to the non-science issues such as the economic and policy options. Unlike more purely descriptive textbooks, it contains the quantitative depth that is necessary for an adequate understanding of the science of climate change. The goal of the book is for a student to leave the class ready to engage in the public policy debate on this issue. This is an invaluable textbook for any introductory survey course on the science and policy of climate change, for both non-science majors and introductory science students.

    At present, Lake Powell is less than half full. Bathtub rings ten stories tall encircle its blue water; boat ramps and marinas lie stranded and useless. To refill it would require surplus water—but there is no surplus: burgeoning populations and thirsty crops consume every drop of the Colorado River. Add to this picture the looming effects of global warming and drought, and the scenario becomes bleaker still. Dead Pool, featuring rarely seen historical photographs, explains why America built the dam that made Lake Powell and others like it and then allowed its citizens to become dependent on their benefits, which were always temporary. Writing for a wide audience, Powell shows us exactly why an urgent threat during the first half of the twenty-first century will come not from the rising of the seas but from the falling of the reservoirs.
