In this dazzlingly original book, archaeologist Brian Fagan shows that such effects are not new: El Nino has been disrupting weather patterns on and off for at least 5,000 years, sometimes with catastrophic effects on civilizations. El Nino-driven droughts have brought on the collapse of dynasties in Egypt; El Nino monsoon failures have caused historic famines in India; and El Nino floods have destroyed whole civilizations in Peru and changed the course of European exploration. These events were not isolated but had lasting influence on the later course of these civilizations for centuries.
