Climate change poses a serious threat to U.S. national security and is becoming a “catalyst for conflict” in vulnerable countries, according to a panel of retired military leaders speaking at the Wilson Center on May 15. [Video Below]

Will climate change cause conflict? That question, which has sparked heated debates in academia and the media, resists simple answers. But is climate change already contributing to conflict in some places? If so, how exactly? And more importantly, what should be done about it? These questions were the focus of a 2013 preliminary report produced for USAID by international development firm Tetra Tech ARD, which examines the climate-conflict nexus in Uganda, Ethiopia, and Peru.

You might wonder what the Cold War has to do with climate change, but as I listened last month to historian James Graham Wilson talk about the “triumph of improvisation” that ended the nearly 50-year stare-down between the United States and the U.S.S.R., I was struck by the parallels. The idea of individual leaders escaping the momentum of conventional approaches and adapting on the fly to solve a major global issue deeply resonated with me. It’s exactly what international climate change negotiations desperately need.

Years ago, when I was a diplomatic correspondent at a large national magazine, if I encountered what I thought of as “science stuff,” I sent it to the science desk. I was busy covering foreign policy, wars, and ethnic and religious conflicts – not science. It was only when I took a new job focused on educating the U.S. media on a wide range of international issues that I began to discover the rich world I had overlooked, and see new links and connections.

With almost 800 million people currently lacking access to clean water and two-thirds of the world’s population projected to face conditions of severe water stress by 2025, disputes over water are a growing global concern. But while dwindling water supplies sharpen focus on conflict, long-term peacebuilding opportunities are often overlooked. [Video Below]
