This book is a bit of a grab-bag at this point, having been compiled from past 'New Yorker' pieces and then updated again more recently. Kolbert's dispassionate tone and comprehensive reporting create a snapshot of a rolling disaster; someday it will be yet one more piece of evidence that we have been willfully blind and irresponsible with our planet. She interviews people who've identified the problems and people who've identified solutions, but the real question is, how to get people moving forward together, without ideology, toward saving ourselves from catastrophe?
