140917-N-TB118-036 NEWPORT, R.I. (Sept. 17, 2014) Daniel Yergin, author, global energy expert and Pulitzer Prize winner for “The Prize: The Epic Quest for Oil, Money and Power,” provides remarks during the Chief of Naval Operations’ 21st International Seapower Symposium (ISS) at U.S. Naval War College in Newport, Rhode Island. More than 170 senior officers and civilians from more than 100 countries, including many of the senior-most officers from those countries’ navies, are currently attending the biennial event Sept. 16-19. This year’s theme is “Global Solutions to Common Maritime Challenges,” and will feature guest speakers and three panel discussions to explore shared global concerns: "Future Trends in Maritime Security," "Maritime Implications of Climate Change," and "Enhancing Coalition Operations." First held in 1969, ISS has become the largest gathering of maritime leaders in history and provides a forum for senior international leaders to create and solidify solutions to shared challenges and threats in ways that are in the interests of individual nations.
