Obama Speaks of 'Peril' of Climate Change in Coast Guard Address

US President Barack Obama delivered the commencement address at the US Coast Guard Academy on May 20, telling cadets that climate change constituted “a serious threat to global security,” and that the need to “combat and adapt” to it would shape their careers. He said that while fighting terrorism remained a priority, the US could not “ignore a peril that can affect generations.” Climate change deniers, he said, are a danger to national security.
