Civil war linked to climatic changes, US researchers find.

Guardian: “Cyclical climatic changes double the risk of civil wars, with analysis showing that 50 of 250 conflicts between 1950 and 2004 were triggered by the El Niño cycle, according to scientists.”“Researchers connected the climate phenomenon known as El Niño, which brings hot and dry conditions to tropical nations and cuts food production, to outbreaks of violence in countries from southern Sudan to Indonesia and Peru. Solomon Hsiang, who led the research at Columbia University, New York, said: “We can speculate that a long-ago Egyptian dynasty was overthrown during a drought. This study shows a systematic pattern of global climate affecting conflict right now. We are still dependent on climate to a very large extent.”
