"A report released Monday indicates the Department of Defense has dramatically shifted its views towards climate change, and has already begun to treat the phenomenon as a significant threat to national security. Climate change, the Pentagon writes, requires immediate action on the part of the U.S. Military.
The report is a “roadmap” of the Department’s future needs and actions to effectively respond to climate change, including anticipating that climate change may require more frequent military intervention within the country to respond to natural disasters, as well as internationally to respond to “extremist ideologies” that may arise in regions where governments are destabilized due to climate-related stressors.
"The impacts of climate change may cause instability in other countries by impairing access to food and water, damaging infrastructure, spreading disease, uprooting and displacing large numbers of people, compelling mass migration, interrupting commercial activity, or restricting electricity availability,” the Pentagon writes. “These developments could undermine already-fragile governments that are unable to respond effectively or challenge currently-stable governments, as well as increasing competition and tension between countries vying for limited resources. These gaps in governance can create an avenue for extremist ideologies and conditions that foster terrorism.”
The military is integrating climate change considerations into all its operations, including in its training for war scenarios........."
