Holdren - Harvard University Professor of Environmental Policy, President Woods Hole Research Center, and Board Chair of American Association for the Advancement of Science (AAAS)

Dr. Holdren was invited to present the annual Chafee Memorial Lecture on climate change at the 8th Conference on Science Policy & the Environment in Washington, D.C. on January 17, 2008.  This is an excellent discussion of the impacts of climate change presented by a highly respected scientist speaking to his peers.  The presentation is not highly technical and is appropriate for any audience.  Well worth the time to listen to his presentation.  Other videos of presentations at the same conference are available at the same website.
