"Critical infrastructure, major military installations, and hurricane evacuation routes are increasingly vulnerable to impacts, such as higher sea levels, storm surges, and flooding exacerbated by climate change.

Expanding on the president's National Strategy for the Arctic Region document from May 2013, the report says the Arctic region offers a "vivid case study" that reveals how climate change and national security are intertwined.
"Temperatures in the Arctic are rising at twice the rate of the rest of the world on average, and melting glaciers and land-based ice sheets are contributing to rising sea levels," the report states.
