On March 30-31, 2007, the Strategic Studies Institute (SSI) and the Triangle Institute for Security Studies (TISS) held a colloquium on “Global Climate Change: National Security Implications.” The 2-day event took place in Chapel Hill, North Carolina, and was well- attended by both academics and members of the U.S. Government and the Armed Forces. This edited volume is based on this event. It reflects, as closely as possible, the form and content of the conference. Each chapter is based on a conference panel. The final chapter contains a keynote talk by General Paul Kern (USA-Ret.) and concluding remarks by Dr. Richard Weitz. The first seven chapters each contain three essays, a comment, and a discussion. The essays are not exact reproductions of the talks given at the conference. They remain true in spirit and length to the originals but have been adapted to be read. The question and answer sessions have been abbreviated in the interests of space. The reader who would like to hear exactly what was said at the conference is invited to turn to the video-taped proceedings which are posted on the TISS web site at www.tiss-nc.org.
