13 October 2014 WASHINGTON (The New York Times) – The Pentagon on Monday released a report asserting decisively that climate change poses an immediate threat to national security, with increased risks from terrorism, infectious disease, global poverty, and food shortages. It also predicted rising demand for military disaster responses as extreme weather creates more global humanitarian crises. The report, 2014 Climate Change Adaptation Roadmap  [pdf], lays out a road map to show how the military will adapt to rising sea levels, more violent storms and widespread droughts. The Defense Department will begin by integrating plans for climate change risks across all of its operations, from war games and strategic military planning situations to a rethinking of the movement of supplies. Defense Secretary Chuck Hagel, speaking Monday at a meeting of defense ministers in Peru, highlighted the report’s findings and the global security threats of climate change. “The loss of glaciers will strain water supplies in several areas of our hemisphere,” Mr. Hagel said. “Destruction and devastation from hurricanes can sow the seeds for instability. Droughts and crop failures can leave millions of people without any lifeline, and trigger waves of mass migration.” The report is the latest in a series of studies highlighting the national security risks of climate change. But the Pentagon’s characterization of it as a present-day threat demanding immediate action represents a significant shift for the military, which has in the past focused on climate change as a future risk. Before, the Pentagon’s response to climate change focused chiefly on preparing military installations to adapt to its effects, like protecting coastal naval bases from rising sea levels. The new report, however, calls on the military to incorporate climate change into broader strategic thinking about high-risk regions — for example, the ways in which drought and food shortages might set off political unrest in the Middle East and Africa. Experts said that the broadened approach would include considering the role that climate change might have played in contributing to the rise of extremist groups like the Islamic State. “Climate change and water shortages may have triggered the drought that caused farmers to relocate to Syrian cities and triggered situations where youth were more susceptible to joining extremist groups,” said Marcus D. King, an expert on climate change and international affairs at George Washington University. The Islamic State, often referred to as ISIS, has seized scarce water resources to enhance its power and influence. As the Pentagon plans for the impact of climate change, it is conducting a survey to assess the vulnerability of its more than 7,000 bases, installations and other facilities. In places like the Hampton Roads region in Virginia, where there is the largest concentration of American military sites, rapidly rising sea levels have led to repeated flooding. [more]
