Could the United States Still Lead the World if It Wanted to?

| July 15, 2021

Stephen Walt asks whether the United States is a good model for other liberal states and whether its policy judgments are ones that others should trust and follow, especially with respect to foreign policy.  He argues that—on balance—the answer to both questions is "no."

Increase in Frequency of Nuclear Power Outages Due to Changing Climate

| July 05, 2021

Climate-related changes have already affected operating conditions for different types of energy system, in particular power plants. With more than three decades of data on changing climate, we are now in a position to empirically assess the impact of climate change on power plant operations. Such empirical assessments can provide an additional measure of the resilience of power plants going forward. Here I analyse climate-linked outages in nuclear power plants over the past three decades. My assessment shows that the average frequency of climate-induced disruptions has dramatically increased from 0.2 outage per reactor-year in the 1990s to 1.5 in the past decade. Based on the projections for adopted climate scenarios, the average annual energy loss of the global nuclear fleet is estimated to range between 0.8% and 1.4% in the mid-term (2046–2065) and 1.4% and 2.4% in the long term (2081–2100).

Nuclear Disarmament, Nuclear Energy, and Climate Change

| March 2019

Preventing nuclear war and avoiding catastrophic climate change are two of the most basic challenges facing human civilization in the twenty-first century. While these are separate issues, these challenges are linked in several ways, and both may be affected by the future of nuclear energy. For nuclear energy to provide any substantial part of the low-carbon energy needed in the second half of the twenty-first century would require dramatic growth. This chapter provides an overview of the constraints and risks of nuclear energy growth on that scale, and the necessary steps to address them. In particular, use of nuclear energy at that scale would place unprecedented demands on global systems for verification, control, and security for weapons-usable nuclear materials. Deep reductions in nuclear arms and their eventual prohibition will also require new approaches to managing the vast global stocks of weapons-usable nuclear materials. Politically, nuclear energy may not be able to grow on the scale required unless governments and publics are confident that it will not contribute to the spread of nuclear weapons, creating another link between climate mitigation and nuclear nonproliferation and disarmament.

Q&A with Elizabeth Sherwood-Randall

| July 12, 2017

Elizabeth Sherwood-Randall, former Deputy Secretary of Energy who has served in high-level positions at the White House and Pentagon, joined Harvard Kennedy School’s Belfer Center as a non-resident Senior Fellow in July. Sherwood-Randall is returning to the Kennedy School where she previously collaborated with Ash Carter, the Belfer Center’s newly appointed director, and Graham Allison, who stepped down as Center director this month. We asked Sherwood-Randall to give us some background on her Harvard connections, why she returned, and what she hopes to accomplish as a Senior Fellow.

Cathryn Cluver Ashbrook discusses importance of wording of the G-20 communique on NDR Aktuell Extra (in German)

| July 07, 2017

Cathryn Cluver Ashbrook, Executive Director of the Future of Diplomacy Project, discusses the importance of the final wording of the G-20 communique, particularly with respect to the climate change and energy policy dossiers, noting different approaches to achieve transatlantic compromise. She underlines the importance of high-level meetings such as the G-20 to address critical global challenges, including multilateral responses to North Korea’s provocations and the ongoing conflict in Syria.
