Publishers Weekly,When it comes to global warming and whether or not it's being caused by human actions, the verdict is in. There is no reasonable doubt." Heos (Stronger than Silk) doesn't mince words in this self-described "call to action," as she clearly and effectively details the greenhouse effect, the ice ages and mass extinctions of Earth's history, the scientific evidence behind climate change, the ways human activities contributes to it, and the politicization of the topic. Between chapters, "Be the Change" pages gather tips for those interested in reducing their own environmental impact, particularly where emissions are concerned (eat less meat, purchase more used goods). Well-researched and comprehensible, it's an alarming, but never alarmist, examination of a critical topic. Ages 12-up. Agent: Kelly Sonnack, Andrea Brown Literary Agency. (Feb.) ???
