Despite the urgent need to reduce global greenhouse gas emissions (GHGs), there has been a lack of national climate action leadership in the United States. In this vacuum, the need for subnational action, particularly at the local level, has become essential. But cities only have the authority granted them by their state. Thus, many cities thus take climate action consistent, or in-sync, with their state. However, other cities take climate action inconsistent, or out-of-sync, with their state. This study examines this in-sync, out-of-sync phenomenon using a multilevel, multiple case study approach to determine the multilevel dynamics influencing whether a city is taking climate action. The study compares two states at opposite ends of the climate mitigation spectrum—Idaho, a state not taking any mitigation action, and Washington, a state taking aggressive mitigation action—and two cities within each of these states, with one city in-sync and the other out-of-sync with its state on climate action. The results show ideology/political affiliation as the most significant factor influencing state and city climate policy: progressive leaning cities/state are engaging in climate mitigation action; conservative leaning cities/state are not. This result was expected, but the study revealed many nuances that were not. For example, the strength of a city’s ideological leaning can overcome disabling state authority. Ideological leaning impacts whether non-state actors are a driver or barrier to climate action. Policy experimentation is found only in progressive cities. Co-benefits manifest in different ways, depending on ideological leaning and whether a city is in- or out-of-sync. And policy champion influence can be fully realized only with supportive elected leadership. This study highlights important interplays between drivers and barriers cities face in addressing climate change in a multilevel setting; how those interplays can help or hinder municipal climate action; and strategies cities employ to address challenges they face. The study findings thus contribute to the understanding of why and how cities take climate action, and how barriers to action can be overcome. This understanding is essential for providing a path forward on municipal climate action and accelerating the reduction of municipal GHG emissions.

Buried under ice and snow in Greenland, the abandoned Camp Century holds the remnants of a Danish-American Cold War-era operation left to achieve final disposal beneath a tomb of ice. Nearly 50 years later, climate projections hypothesize that snowmelt will exceed snowfall in 2090—releasing the trapped hazardous wastes at Camp Century. This thesis examines the mechanisms through which the international community is able to remediate climate change impacts on Camp Century wastes. The wastes are characterized and examined as either a problem of transboundary pollution, as an issue of military accountability, or as an issue of climate change policy. As revealed, the wastes are unable to be classified as transboundary pollutants. Though classified as a point-source transboundary risk, they are neither a traded or public risk. Furthermore, no international or domestic transboundary pollution agreements incorporate provisions encompassing the specific attributes of Camp Century’s waste. Camp Century is also not an issue of military accountability as U.S. base cleanup laws and environmental regulations do not apply abroad and as the original bilateral agreement governing the site is insufficient in addressing potential ice melt. Finally, as examined through institutions such as the UNFCCC and the Paris Agreement, Camp Century is, again, unable to be incorporated in current frameworks such as adaptation as adaption efforts are concentrated on developing nations. This thesis reveals the inability of current frameworks, institutions, and agreements to effectively remediate Camp Century wastes which is a case utilized as a microcosm through which to examine international capacity in addressing climate-change induced impacts.

In the last seven years the practice of capital punishment in the United States has been shaken by one of the most unlikely suspects- the prescription drug market. The practice of capital punishment has gone from fervent support to abolishment and back again throughout the nation's history. Over time the process of capital punishment has evolved from public hangings to a secretive medical procedure. The American people have become detached from the act because it is no longer right in front of their face, but often occurs in a small prison room with a viewing window for a select group of witnesses. The modern method of capital punishment is lethal injection- a three-drug protocol that is accepted as the most humane means of executing criminals. The protocol has faced criticism and legal challenges for years. This is in part because the United States stands alone as one of the last westernized democratic nations to regularly execute convicted criminals. European activist groups and government agencies have been fighting for abolishment in the United States for years with little progress. Recently, the activist groups discovered a novel way to make an impact on the capital punishment system in the United States that had not been attempted. The groups appealed to the drug manufacturing companies in Europe and exposed their supply chains to the public. When it was revealed that the drugs these companies produced were ending up in U.S. prisons for executions the companies eventually stopped all sales of execution drugs to U.S. corrections facilities. This led to the European Union banning all exports of drugs for lethal use in 2011. This study will analyze the effects of the lethal injection drug boycott on the death penalty in the United States. Since the ban, death penalty states have been scrambling in order to procure enough drugs to carry out their future executions. They have attempted to obtain the drugs illegally, trade between each other, reinstate older methods of execution, and entirely change their three-drug protocol to incorporate new drugs or less drugs. Executions have dropped both in the number of death sentences handed down and the number of executions. Also, polls analyzing acceptance of the death penalty have shown decreasing support for the practice domestically. Although there are other factors that may have contributed to the decline of capital punishment in the United States, it seems as though the international lethal injection boycott has made the most progress in the shortest amount of time and has the potential to drastically change the future of the death penalty in the United States.
