A major peer-reviewed study called “Climate change in the the Fertile Crescent and implications of the recent Syrian drought” published last March found that global warming made Syria’s 2006-2010 drought two to three times more likely and therefore should be considered as a significant catalyst behind the exodus of vulnerable migrants into cities and the arms of ISIS recruiters.
“While we’re not saying the drought caused the war,” lead author Colin Kelley explained. “We are saying that it certainly contributed to other factors — agricultural collapse and mass migration among them — that caused the uprising.”
