Brian Fagan's The Great Warming

Here's an audio interview of Brian Fagan, author of The Great Warming: Climate Change and the Rise and Fall of Civilizations. The recording is very soft; I had to turn up the volume on my speakers all the way to make it out. The headline on the front page of the National Review website ran, "Brian Fagan says global warming was a positive force in the development of the West during the Middle Ages." Uh, no ... he says it was both good and bad, depending. A far more accurate description is that found on the "Between the Covers" page, which states that Fagan argues that "the warming period of 800-1200 A.D. had its good and bad sides."
