The Commander in Chief, Congress, and Climate Security: Who Has the Authority?
Climate change is the worldâs greatest environmental threat. It is also increasingly understood as a threat to domestic and international peace and security â recognized by the Department of Defense as a âthreat multiplier,â by Secretary of State John Kerry as âperhaps the worldâs most fearsome weapon of mass destruction,â and by President Obama, in an address to graduates of the United States Military Academy, as âa creeping national security crisis.â The Supreme Courtâs temporary blocking of the Clean Power Plan highlights the Federal-State divide over how to address climate change, but because of its national security dimension, climate change also raises unique separation-of-powers issues between the president and Congress with regard to how the military can respond.
