"global warming is said to have played a role in sparking the 2011 uprising. Severe drought plagued Syria from 2007-10, causing as many as 1.5 million people to migrate from the countryside into cities, exacerbating poverty and social unrest."
A not unreasonable hypothesis. Yet the bulk of the destruction is the result of ghastly military actions, aimed at direct destruction of the society. To worry about the contribution of climate change is not pointless. Close to it though.
