Koonin received his Bachelor of Science from Caltech and his Ph.D. from the Massachusetts Institute of Technology. In 1975, Koonin joined the faculty of the California Institute of Technology as a Professor of Theoretical Physics, and served as the Institute's provost from 1995 to 2004. In 2004, Koonin joined BP as their Chief Scientist where he was responsible for guiding the company’s long-range technology strategy, particularly in alternative and renewable energy sources. In 2009, he was appointed the U.S. Department of Energy’s second Senate-confirmed Under Secretary for Science serving from May 19, 2009 through November 18, 2011. He left that post in November 2011 for a position at the Institute for Defense Analyses. On April 23, 2012, Koonin was named director of NYU's Center for Urban Science and Progress (CUSP).
He has served on numerous advisory bodies for the National Science Foundation, the Department of Defense, and the Department of Energy and its various national laboratories. Koonin's research interests have included theoretical nuclear, many-body, and computational physics, nuclear astrophysics, and global environmental science.
Views on Climate Science
In "Climate Science Is Not Settled," a 2014 essay published in the Wall Street Journal, Koonin wrote that "We are very far from the knowledge needed to make good climate policy," and that "The impact today of human activity [on climate] appears to be comparable to the intrinsic, natural variability of the climate system itself." Koonin criticized the use of results from climate modelling to support the "scientific consensus" (quotes in original) about climate change, noting that, among other problems, "The models differ in their descriptions of the past century's global average surface temperature by more than three times the entire warming recorded during that time." Regarding climate sensitivity, Koonin wrote that "Today's best estimate of the sensitivity (between 2.7 degrees Fahrenheit and 8.1 degrees Fahrenheit) is no different, and no more certain, than it was 30 years ago. And this is despite an heroic research effort costing billions of dollars."
