Little by little the skeptics of global warming are falling away. Let's hope this brief and very persuasive book shakes loose a few more of them, because Kolbert, an unbiased reporter and one of the best non-fiction writers of English today, makes it clear that the time to act on anthropogenic climate change is ten years ago. Were it not that the subject matter is inherently depressing, this book would be a sheer pleasure to read---and as it is, it can and should be read by everyone who has a middle school diploma. If you are considering buying it, stop reading the reviews right now and make the purchase. Then read it and pass it on.
