Naomi Oreskes is Professor of History and Science Studies at the University of California, San Diego, Adjunct Professor of Geosciences at the Scripps Institution of Oceanography, and an internationally renowned historian of science and author. Having started her career as a geologist, she received an inter-disciplinary Ph.D. in geological research and history of science from Stanford University, in 1990. Professor Oreskes has lectured widely in diverse venues, and has won numerous prizes, including, most recently the 2011 Climate Change Communicator of the Year. Professor Oreskes has a long-standing interest in understanding the establishment of scientific consensus and the role and character of scientific dissent. Her early work examined the 20th century transformation of earth science, in The Rejection Continental Drift: Theory and Method in American Earth Science (Oxford, 1999) and Plate Tectonics: An Insider's History of the Modern Theory of the Earth (Westview, 2001). For the past decade, Professor Oreskes has primarily been interested in the problem of anthropogenic climate change. Her current research projects include completion of a book on the history of Cold War Oceanography, Science on a Mission: American Oceanography in the Cold War and Beyond (Chicago, forthcoming), and Assessing Assessments: A Historical and Philosophical Study of Scientific Assessments for Environmental Policy in the Late 20th Century, funded by the National Science Foundation.
