The narrow window of opportunity to address climate change makes it imperative that we “remove our heads from the proverbial sand,” writes editor Carolyn Pumphrey in “Global Climate Change: National Security Implications,” released by the U.S. Army War College earlier this month. The report aggregates the presentations given at a 2007 colloquium by the same name in Chapel Hill, North Carolina, and features contributions from several authors who have worked recently with ECSP, including Kent Hughes Butts, Joshua Busby, and John T. Ackerman (who has also been a guest contributor to the New Security Beat).

The risks associated with climate change include the spread of disease, severe drought, and coastal flooding, which could lead to decreased agricultural output, mass migration, and other challenges. Pumphrey writes that while social scientists are not in full agreement that violence will result from these developments, conference participants agreed that climate change presents a serious threat, “compounded by a context of rapid population growth, increasing economic appetite, pockets of extreme violence, and global interdependence.” By inflaming latent tensions, climate change will “complicate American foreign policy in a wide variety of ways,” says Pumphrey.

Since the Senate Armed Services Committee called environmental destruction a “growing national security threat” in the late 1990s, some effort has been devoted to crafting a U.S. response, but politicians have hesitated to act on uncertain scientific data, says Pumphrey, arguing additionally that the creeping dangers associated with climate change have only recently begun to captivate the public imagination, and that attempts to spice them up can lead to inaccurate exaggeration. Finally, Pumphrey says, pervasive overconfidence in the ability of “American ingenuity” to outpace emerging dangers has hindered decisive action.

Pumphrey calls for a three-pronged strategy that includes “better intelligence, better science, and better understanding of the relationships between such things as violence, society, and climate change.” She maintains that we must slow the rate of climate change and prepare for unavoidable changes, take action to alleviate international social distress, and prepare to address potential conflicts. And, she notes, this is “a job for everyone,” not just the military.
