US Military

American military leaders discuss the rising national security implications of climate change in a New York Times article, "Climate Change Seen as Threat to U.S. Security" (August 8, 2009). The article states that the National Intelligence Council "concluded that climate change by itself would have significant geopolitical impacts around the world and would contribute to a host of problems, including poverty, environmental degradation and the weakening of national governments."

The article also quotes a report from Gen. Anthony C. Zinni, a retired Marine and the former head of the Central Command, prepared as a member of a military advisory board on energy and climate at CNA, a private group that does research for the Navy. “We will pay to reduce greenhouse gas emissions today, and we’ll have to take an economic hit of some kind. Or we will pay the price later in military terms. And that will involve human lives.”
