The world's first empire, Akkad, was toppled 4,000 years ago by a disastrous drought in Mesopotamia, Ancient Rome experienced 18 months of darkness, possibly from a volcanic eruption half a world away, and Mayan society in Mexico began to crumble… when fresh water became scarce. Christie explores climate shifts of the past, from ice ages to a World War II El Niño that frustrated the battle plans of Hitler. Grades 4-7. 2008.
