An overview of global warming discusses its causes; consequences for habitats, flora, fauna, and people around the globe; and potential solutions, and presents more than fifty things that ordinary people can do to help. Planet Earth is heating up, and so is the debate over why our climate is changing and what it means for the future of our energy sources, of our cities, of our children. Now "Time" explores the science of global warming in an illuminating, beautifully illustrated book that ranges from polar ice caps to equatorial rainforests. Here are the scientists who are working to measure and counter the warming trend; here are the world's most endangered habitats and creatures; here are various scenarios for the future. Separating truth from fantasy, "Time" brings a cool eye to today's hottest issue.
