Science, Technology, and Public Policy

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

Harvard University has created a Presidential Committee on Sustainability (PCS) to advise President Larry Bacow and the University's leadership on sustainability vision, goals, strategy, and partnerships. The Harvard Gazette spoke with committee chairs Rebecca Henderson, the John and Natty McArthur University Professor; John Holdren, the Teresa and John Heinz Professor of Environmental Policy at Harvard Kennedy School; and Katie Lapp, executive vice president, about why it is so important to act now; the role of the PCS in developing collaborative and innovative projects; and how the campus community can get involved.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.

The arguments in favor of the United States' declaring that the only purpose of its nuclear weapons is to deter others who possess them from using theirs — in other words, that in no circumstances will this country use nuclear weapons first — are far stronger than the arguments against this stance. It must be hoped that the next US administration will take this no-first-use step promptly.

In this edition of "The Interview," Fair Observer talks to Professor John Holdren, former science adviser to President Barack Obama and director of the White House Office of Science and Technology Policy from 2009 to 2017 about the impacts of global warming on the United States and the government's strategies to combat climate change.
