Arguing that climate change and global warming affect us all and that we can be part of the solution, this comprehensive look at the issue includes a clear explanation of the mechanism of the carbon cycle, the role of greenhouse gases on Earth, historical instances of climate change and their causes, descriptions of effects on a variety of habitats, future scenarios and suggestions—both personal and global—about what might be done. An adaptation for teen readers of Flannery’s highly regarded and influential adult title (The Weather Makers, 2006), Walker’s readable and convincing rewrite follows the original organization but tightens up the text, shortening chapters and addressing the intended readers with action suggestions between each chapter. It includes new research and four examples of institutions and groups whose actions have made a difference in greenhouse-gas emissions. Endnotes and an extensive bibliography support the argument. A copy belongs in every middle- and high-school library. (index) (Nonfiction. 14 & up)
