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.”
