How the earth’s previous global warming phase, from the tenth to the fifteenth centuries, reshaped human societies from the Arctic to the Sahara—a wide-ranging history with sobering lessons for our own time. From the tenth to the fifteenth centuries the earth experienced a rise in surface temperature that changed climate worldwide—a preview of today’s global warming. In some areas, including Western Europe, longer summers brought bountiful harvests and population growth that led to cultural flowering. In the Arctic, Inuit and Norse sailors made cultural connections across thousands of miles as they traded precious iron goods. Polynesian sailors, riding new wind patterns, were able to settle the remotest islands on earth. But in many parts of the world, the warm centuries brought drought and famine. Elaborate societies in western and central America collapsed, and the vast building complexes of Chaco Canyon and the Mayan Yucatan were left empty. As he did in his bestselling The Little Ice Age, anthropologist and historian Brian Fagan reveals how subtle changes in the environment had far-reaching effects on human life, in a narrative that sweeps from the Arctic ice cap to the Sahara to the Indian Ocean. The history of the Great Warming of a half millennium ago suggests that we may yet be underestimating the power of climate change to disrupt our lives today—and our vulnerability to drought, writes Fagan, is the “silent elephant in the room.” The New York Times - William Grimes …[a] fascinating account of shifting climatic conditions and their consequences from about A.D. 800 to 1300, often referred to as the Medieval Warm Period…Mr. Fagan, an anthropologist who has written on climate change in The Long Summer and The Little Ice Age, proceeds methodically, working his way across the globe and reading the evidence provided by tree rings, deep-sea cores, coral samples, computer weather models and satellite photos. The picture that emerges remains blurry…but it has sharpened considerably over the past 40 years, enough for Mr. Fagan to present a coherent account of profound changes in human societies from the American Southwest to the Huang He River basin in China.
