Michael Oppenheimer

Michael Oppenheimer (born February 28, 1946) is the Albert G. Milbank Professor of Geosciences and International Affairs in the Princeton School of Public and International Affairs, the Department of Geosciences, and the High Meadows Environmental Institute at Princeton University. He is the director of the Center for Policy Research on Energy and the Environment (C-PREE) at the Princeton School of Public and International Affairs and Faculty Associate of the Atmospheric and Ocean Sciences Program and the Princeton Institute for International and Regional Studies.

Oppenheimer has played a leading role at the interface of science and public policy including influencing the development of the acid rain provisions of the US Clean Air Act. He co-organized a series of activities that prefigured the emergence of climate change as a top international concern and influenced the development of the United Nations Framework Convention on Climate Change. He directed climate and air pollution activities at the Environmental Defense Fund when that NGO's science-based and incentive-based approach to climate change was reflected in the language of the Kyoto Protocol. Oppenheimer has played a significant role within the Nobel Prize-winning Intergovernmental Panel on Climate Change (IPCC), serving as Contributing Author, Lead Author, or Coordinating Lead Author on each assessment report since IPCC's first report, as well as two special reports. Oppenheimer also serves as a Review Editor on the Sixth Assessment Report.

Oppenheimer is a prominent public figure and has discussed various aspects of the impacts of and solutions to climate change and other issues in the media. He has testified before committees of the US Senate and House of Representatives on numerous occasions. He has also been a guest on many television and radio programs and talk shows, including This Week, The News Hour, The Oprah Winfrey Show, The Colbert Report, and 60 Minutes. Oppenheimer is the author of over 200 articles published in professional journals.

He is the author of Discerning Experts: The Practices of Scientific Assessment for Environmental Policy published in 2019 with several coauthors and Dead Heat: The Race Against The Greenhouse Effect, coauthored with Robert H. Boyle and published in 1990. Oppenheimer is co-founder of the Climate Action Network and has served on many expert panels including the New York City Panel on Climate Change and the US National Academies’ Board on Energy and Environmental Systems. He is a trustee of the NGOs Climate Central and Climate Science Legal Defense Fund. Oppenheimer also serves as co-editor-in-chief of the journal Climatic Change.

In 1989, Oppenheimer founded the Climate Action Network of over 1300 non-governmental organizations in over 130 countries working to limit human-induced climate change to ecologically sustainable levels.

Oppenheimer is not related to the nuclear physicist J. Robert Oppenheimer.

Background Oppenheimer was born February 28, 1946, in New York City.

He received an S.B. in chemistry from MIT, a Ph.D. in chemical physics from the University of Chicago, and pursued post-doctoral research at the Center for Astrophysics Harvard & Smithsonian.

He joined the Princeton faculty after more than two decades with the Environmental Defense Fund (EDF), a non-governmental, environmental organization, where he served as chief scientist and manager of the Climate and Air Program. Prior to his position at the Environmental Defense Fund, Oppenheimer served as atomic and molecular astrophysicist at the Center for Astrophysics Harvard & Smithsonian and lecturer on astronomy at Harvard University.

He continues to serve as a science advisor to EDF.

Oppenheimer won the 2010 Heinz Award in the Environment and is a Fellow of the American Association for the Advancement of Science. Oppenheimer studies the process of scientific learning and scientific assessments and their role in influencing public policies to respond to global change.

Role in global science policy Oppenheimer is a long-time participant in the Intergovernmental Panel on Climate Change (IPCC) which won the Nobel Peace Prize in 2007, serving recently as a Coordinating Lead Author of the Special Report on the Ocean and Cryosphere in a Changing Climate. In the late 1980s, Dr. Oppenheimer and a handful of other scientists organized two workshops under the auspices of the United Nations that helped precipitate the negotiations that resulted in the United Nations Framework Convention on Climate Change (signed at the 1992 Earth Summit) and the Kyoto Protocol. During that period, he co-founded the Climate Action Network. His research and advocacy work on acid rain also contributed to the passage of the 1990 amendments to the Clean Air Act and influenced the development of the Kyoto Protocol.

Assessment of the IPCC process In 2007, he wrote about limitations of the IPCC consensus approach in Science Magazine. According to him, the "problem of creating, defending, and communicating consensus, as well as departures from the consensus" had been discussed but not addressed until after the AR4. Oppenheimer and coauthors pursued the theme of treatment of uncertainty in assessments in subsequent papers, particularly Climate change prediction: erring on the side of least drama? (2013) and in the 2019 book, Discerning Experts: The Practice of Scientific Assessment for Environmental Policy. The latter reports the results of the first phase of an ongoing ethnographic study of many assessments that includes, in its subsequent phases, direct observation of parts of IPCC author meetings and consensus panels of the US National Research Council/National Academy of Sciences.
