Over the last half a billion years, there have been five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In The Sixth Extinction, two-time winner of the National Magazine Award and New Yorker writer Elizabeth Kolbert draws on the work of scores of researchers in half a dozen disciplines, accompanying many of them into the field: geologists who study deep ocean cores, botanists who follow the tree line as it climbs up the Andes, marine biologists who dive off the Great Barrier Reef. She introduces us to a dozen species, some already gone, others facing extinction, including the Panamian golden frog, staghorn coral, the great auk, and the Sumatran rhino. Through these stories, Kolbert provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy; as Kolbert observes, it compels us to rethink the fundamental question of what it means to be human.
Americans have been warned since the late 1970s that the buildup of carbon dioxide in our atmosphere threatens to melt the polar ice sheets and irreversibly change our climate. With little done since then to alter this dangerous path, the world has reached a critical threshold. By the end of the century, it will likely be hotter than at any point in the last two million years, and the sweeping consequences of this change will determine the future of life on earth for generations to come.
Taking listeners from the melting Alaskan permafrost to storm-torn New Orleans, acclaimed journalist Elizabeth Kolbert approaches this monumental problem from every angle. She interviews researchers and environmentalists, explains the science, draws frightening parallels to lost civilizations and presents the moving tales of people who are watching their worlds disappear. Growing out of an award-winning three-part series for the "New Yorker, Field Notes from a Catastrophe brings the environment into the consciousness of the American people and asks what, if anything, can be done to save our planet.
