Interview with interviews Michael Oppenheimer, Professor of Geosciences and International Affairs and the High Meadows Environmental Institute at Princeton University. Oppenheimer describes the three-way nature of his work at Princeton, between the School of Public and International Affairs and the Science, Technology, and Environmental Policy program. He describes the possibilities for climate change policy in the transition from Presidents Trump to Biden, and he discusses the moral dimension to climate change diplomacy and what the “Global North” owes the “Global South.” Oppenheimer recounts his childhood in Queens, the opportunities that allowed him to enroll at MIT at age 16, and his decision to focus on chemistry and to become involved in political activity in the 1960s. He explains his decision to go to the University of Chicago for graduate school, where he studied under the direction of Steve Berry on low-temperature spectroscopy of alkali halides. Oppenheimer describes his postdoctoral research at what would soon become the Center for Astrophysics at Harvard to work on astrophysics from an atomic and molecular perspective and on the chemistry of comets. He explains how the acidification issue in the Adirondack Lakes serves as an entrée to his interests in environmental policy and how this led to his work for the Environmental Defense Fund. Oppenheimer describes his work on the linearity question and why it is relevant for understanding carbon emissions and his advocacy work on the Clean Air Act. He explains the early science that concluded that even a few degrees of warming would be globally catastrophic, and the early signs that the Republican party would serve generally to block legislation to mitigate climate change. Oppenheimer discusses his involvement with international climate negotiations and policy with the IPCC and the issue of contrarianism in global warming debates. He contrasts the simplicity of the greenhouse effect with the complexity of understanding climate change, and he explains his decision to move to Princeton within the context of what he thought the Kyoto Protocol had achieved. Oppenheimer reflects on how climate change has increased in the public consciousness, and at the end of the interview, he considers early missed opportunities for more change in climate policy, and where he sees reason for both optimism and pessimism as the world faces future threats relating to climate change.

This interview is part of a series conducted during research for the book Tunnel Visions, a history of the Superconducting Super Collider project. It primarily addresses Princeton University physicist William Happer’s time as the Director of the Office of Energy Research at the Department of Energy, a position he held from May 1991 to May 1993. This period covers the ramp up of construction on the project and the growth of congressional opposition to it, as well as the transition from the administration of President George H. W. Bush to that of President Bill Clinton. Happer addresses his own support for the project, other scientific efforts competing for priority, the political dynamics he perceived surrounding the SSC, and his views of the management structure for the SSC that DOE implemented prior to his arrival. He observes that the management and fate of the SSC were not especially unusual in the context of other expensive DOE projects and discusses at length the failure to secure international support for the SSC, particularly the difficulty in making the project a top-priority issue in diplomacy with Japan. Happer also offers his perception of the Clinton administration’s lukewarm support for the project, the possibility it could have been politically saved, and the dangers it would have faced if it continued beyond 1993. He also reflects on whether large-scale projects such as the SSC are urgent to pursue, defends Roy Schwitters’s performance as SSC Laboratory Director, and shares his views of the ferocity of the SSC’s main opponents in Congress and of the role of Congress’s General Accounting Office in building the case against it.
