President Obama delivered the keynote address at the United States Coast Guard Academy commencement Wednesday in New London, Connecticut. In his commencement speech, Obama warned graduates climate change is one of the largest threats they will have to face as they defend the United States and our nation’s interests abroad.

In his speech, Obama said denying climate change or refusing to deal with it is negligence and “dereliction of duty.”

“If you see storm clouds gathering or dangerous shoals ahead you don’t just sit back and do nothing,” President Obama said Wednesday. “You take action to protect your ship, to keep your crew safe. Anything less is negligence. It is a dereliction of duty. So to with climate change.”

“Denying it or refusing to deal with it endangers our national security,” Obama also said. “It undermines the readiness of our forces.”
