Why does the U.S. Army rely on persuasion to influence military partners to improve their forces despite repeated failures that undermine U.S. foreign policy goals? The army prioritizes its role as a fighting force, not an advisory group. U.S. leaders have developed an ideology—the cult of the persuasive—to advance army bureaucratic interests.

We used the US-TIMES energy-system model in conjunction with integrated assessment models for air pollution (AP3, EASIUR, InMAP) to estimate the consequences of local air pollutant (LAP) and carbon dioxide (CO₂) policy on technology-choice, energy-system costs, emissions, and pollution damages in the United States. We report substantial policy spillover: Both LAP and CO₂ taxes cause similar levels of decarbonization. Under LAP taxes, decarbonization was a result of an increase in natural gas generation and a near-complete phaseout of coal generation in the electric sector. Under a CO₂ tax, the majority of simulated decarbonization was a result of increased electric generation from wind and solar. We also found that the timing of the CO₂ and LAP taxes was important. When we simulated a LAP tax beginning in 2015 and waited until 2025 to introduce a CO₂ tax, the electric sector was locked into higher levels of natural gas generation and cumulative 2010–2035 energy system CO₂ emissions were 8.8 billion tons higher than when the taxes were implemented simultaneously. A scenario taxing CO₂ and LAPs simultaneously beginning in 2015 produced the highest net benefits, as opposed to scenarios that target either CO₂ or LAPs, or scenarios that delayed either LAP or CO₂ taxes until 2025. Lastly, we found that net benefits compared to business as usual are higher under a regional versus a national LAP-tax regime, but that efficiency gains under the regional tax are not substantially higher than those under the national LAP-tax policy.

Opportunistic repression arises when states use crises to suppress the political opposition. An examination of the relationship between COVID-19 shutdown policies and state violence against civilians in Africa, including and a subnational case study of Uganda, tests this theory.

A comparative analysis of the United States’ and the Soviet Union’s previously underexplored radiological weapons programs identifies the drivers behind their rise and demise. The findings of this analysis illuminate the factors likely to affect the pursuit of radiological weapons by other states in the future.

The peer-reviewed update of ENRP's ongoing research on renewable hydrogen is featured in the June volume of Geopolitics, History, and International Relations, an academic journal of which Dr. Nicola de Blasio is now also an editor.

SWJ interview with Nathaniel L. Moir, Ph.D., an Ernest May Postdoctoral Fellow in History and Policy at the Belfer Center for Science and International Affairs, Harvard Kennedy School. Dr. Moir is completing a book manuscript on Bernard Fall for publication.

The 1970 Clean Air Act established the basic architecture of the U.S. air pollution control system: It was the first environmental law to give the federal government a serious regulatory role, and it became a model for many subsequent environmental laws in the United States and abroad. In this article, the authors describe the evolution of air pollution control policy under this legislation with particular attention to the types of policy instruments used.

Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

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.
