The Great Warming -- medieval climate change in Europe and the world

Brian Fagan has written a book called The Great Warming: Climate Change and the Rise and Fall of Civilizations, about the effect that the warming period between 800-1200 A.D. had on global living standards. There's a preview of his argument on NRO Radio. He also talks about fishing!
