When Pakistan makes the news, more often than not it’s for one of two things: violent extremism or drone strikes. Adil Najam, a Pakistan expert and a lead author for the UN’s Intergovernmental Panel on Climate Change, says those headlines distract from a far more pressing security concern for the country: climate change.

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]

“We have a fairly unique moment in the history of the world,” said Steven Philip Kramer, a professor at National Defense University, at the Wilson Center on April 17. “There’s never been a time when people have voluntarily produced fewer children than is necessary for sustaining the population.” [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.

In 2007, an influential analysis by 11 retired generals and admirals characterized climate change as a “threat multiplier” that could aggravate the conditions for conflict. Last week, in a follow-up report launched at the Wilson Center, members of the CNA Corporation’s Military Advisory Board framed climate change as a more direct and immediate risk, calling it a “catalyst for conflict.”

Last September, facing a growing public outcry to ease smog, China’s State Council called for the accelerated development of a new energy industry that turns coal into methane gas. Piped to Beijing and other cities, this gas could help cut down on smog by replacing dirtier fuels now used to cook meals, heat homes, and produce electricity. But embracing it involves a major environmental trade-off in overall carbon emissions.

Last year, the International Committee of the Red Cross (ICRC) celebrated 150 years of their mission to “protect the lives and dignity of victims of war and internal violence.” Though this mission hasn’t changed in the past century-and-a-half, the nature of conflict and crisis response has. [Video Below]
