Gr 9 Up-Comprehensive and thorough, this much-needed work explains the basic science required to understand and enter discussions on global warming and climate change. Through a question-and-answer format, Bennett presents the research in a conversational style. Divided into sections, the work explores the concepts and facts surrounding climate science and the potential worldwide consequences if steps are not taken to reduce energy consumption. The text also addresses common misconceptions and skepticism about the subject. On a more optimistic note, the author does provide possible and currently available solutions as well as those that may develop in the future. Numerous graphs, charts, and images help clarify concepts and enable even the less scientifically literate to easily understand the theories covered. Without moralizing, Bennett offers strong evidence for the effects of global warming and urges cooperation and action across political party and international lines to prevent a calamitous future. VERDICT Readable and informative, this valuable support tool for science curricula is a solid addition to high school libraries.
