VOYAThese two excellent Understanding Global Issues series entries, Earth's Changing Climate and Renewable Energy Resources, join other books on Antarctica, gridlock, and healthy cities in this ongoing series. Earth's Changing Climate presents a balanced examination of the concerns and debate surrounding global warming. The facts and the arguments are provided in nonbiased language that allows readers to draw their own conclusions. If there is one flaw in the presentation of information, it might be that quotes taken out of context can present a distorted picture; however, that occurrence is rare in the text. Renewable Energy Resources examines different energy sources, how they are used currently, and what the projected use will be. It covers wind, water, and solar energy, and spends a marginal amount of time on bio-energy or biomass. It also strives to present a balanced view, although it is less balanced than the first title. The layout and presentation of each book is particularly well done. The titles use color photographs and charts throughout to highlight each concept. There are sidebars with pertinent information such as key concepts, models of equipment, and definitions of programs that are referred to within the main text. Each title also includes sections on careers in the energy industry, a time line of events, biographies, a concept web, a quiz, and a list of resources for further reading. Overall these titles are excellent additions to middle school collections.
