To Enhance National Security, the Biden Administration Will Have to Trim an Exorbitant Defense Wish List

| Mar. 13, 2024

David Kearn argues that even in the absence of restrictive resource and budgetary constraints, a focus on identifying and achieving concrete objectives that will position the United States and its allies to effectively deter aggression in critical regional flashpoints should be the priority given the stressed nature of the defense industrial base and the nuclear enterprise.

Russia and the Global Nuclear Order

| March 2024

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Nuclear Waste

| Aug. 01, 2023

This chapter appears in Handbook of the Anthropocene: Humans between Heritage and Future.

Nuclear waste epitomizes the Anthropocene. Scientific discovery of nuclear fission in the 1930s ushered in the atomic age. The onset of nuclear weapons and nuclear energy production in the 1940s and 1950s then created a uniquely human problem with planetary implications. Today, 33 countries operate 442 nuclear power reactors, and nine countries possess nearly 13,000 nuclear arms. The result is high-level waste that is dangerously radioactive for millennia to come. Yet, there has never been a permanent waste solution in place. Technically feasible long-term nuclear waste storage options exist, but nearly all governments prefer riskier interim plans hidden from public view and debate. This chapter considers the likelihood of societies addressing the contentious environmental and economic politics of deep geological repositories; and it asks, how long will obfuscation of the risks of this unique Anthropocene challenge continue?

Our AI Odyssey

| Nov. 26, 2021

The powerful effects of artificial intelligence are already being felt in business, politics, medicine, war, and almost every other domain of twenty-first century life. For all of its positive potential, the technology presents significant risks that are best addressed sooner rather than later.

Time Wasted and the Urgent Need to Decarbonize

| Aug. 10, 2021

Ian Masters and Joel Clement assess how much time has been lost by governments in facing the looming crisis of climate change, in particular here in the U.S. where the last four years were not only wasted, but were steps backwards from the urgent challenges made clear by yesterday's alarming IPCC report.

Why Biden's Interior Department isn't Shutting Down Oil and Gas

| July 23, 2021

Joel Clement describes the influence of U.S. Senators Lisa Murkowski and Joe Manchin over the Department of the Interior and advises that a forward-looking legislator in a fossil-fuel state would be wise to fight aggressively for financial commitments to make the people in their state part of the vanguard of the new clean energy economy, rather than set back the U.S. economy by fighting the inevitable energy transition itself.

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).
