WHICH CITIES ARE MOST VULNERABLE TO CLIMATE CHANGE CONFLICT?

We know that climate change imperils coastal communities around the world and endangers food and water sources, and that political and religious extremism feed off instability and cause bloodshed. But because each contributes to the other, the future of millions may be at risk. A 2013 University of California–Berkeley study analyzed 60 previous studies and concluded that the connection between climate change and human conflict is strong. Droughts and famines, floods, wildfires, and other events caused at least in part by climate change lead to instability that extremist groups can take advantage of to create conflict. A more recent report by CNA, a research non-profit with national-security expertise, focuses on the connection between water stress and conflict. "Water stress can empower violent extremist organizations and place stable governments at risk," the authors write. Some experts believe we are heading toward a point where water will be more difficult to come by and brutal wars will be fought over control of fresh-water resources.
