A breakout best seller on how the earth's previous global warming phase reshaped human societies from the Arctic to the Sahara.
From the 10th to the 15th 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 Yucatn were left empty.
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.
