Description
This study looks to answer whether or not citizens have reason to believe the publicity statements from state government officials when speaking about gun-control laws during the time surrounding mass shootings. Citizens in America see the same, consistent pattern that politicians use mass shootings for, known as "The Shooting Cycle." Here, we will research whether or not these politicians are continuing to keep the same voting pattern that they have had in the past, in terms of gun control. This case study uses quantitative research to discover that almost all state representative and senators have consistent voting patterns when it comes to gun control legislation, regardless of time distances around mass shootings. We will then seek out seek out public statements and relevant periodicals and media clips in order to determine whether or not these voting patterns align with the public's perception of a politician's stance on gun control. It also uses qualitative research to discover that publicity from senators and representatives that support gun rights have more consistency in their public statements than those who are either inconsistent or consistently vote for gun control legislation. This study creates opportunities for new research in voting patterns and political transparency on state officials and the significant effects of mass shootings on public opinions and public statements from state officials.

Description
The fight for climate justice has been ongoing for decades. However, in a recent effort to address climate change, U.S. congressional leaders Alexandria Ocasio-Cortez of New York and Edward J. Markey of Massachusetts proposed a resolution known as the Green New Deal (GND). Though congress defeated the proposal, the policy changes envisioned within it have gained political momentum from states and municipalities. So much so, municipalities in the United States have decided to implement their own versions of the GND proposal. Throughout this paper, I analyze the components of three nationally recognized climate proposals that offer a unique approach to actualize the federal GND objectives: New York City's Climate Mobilization Act, Los Angeles's Green New Deal – Sustainable City pLAn, and Seattle's Green New Deal. From these proposals, I draw comparisons to Tempe's Climate Action plan to evaluate their efforts. Though this paper is primarily focused on analyzing the components of municipal GNDs across the nation, this paper also contends that municipalities' are a necessary complement to national efforts in mitigating climate change.

Description
Climate change is a global phenomenon that is disproportionately impacting people in developing countries. One coping mechanism that has been observed in response to climate change is migration. This paper attempts to understand the role of climate change as a driver of migration in Papua New Guinea, a complex and under-researched country in Oceania. Past research suggests a complicated story, and that migration in response to climate change is not a simple concept. In order add to the existing literature, a variety of individual, household, and community-level variables are analyzed from a survey of households in rural Papua New Guinea. These variables are analyzed in conjunction with self-reported environmental shocks to determine the impact on migration across time. The results suggest that environmental shocks increase the probability of an individual migrating, with various socioeconomic factors acting as push and pull factors.

Description
This past summer, Pew Research Center conducted a ten-question survey to test Americans' knowledge on current events. Questions ranged from how Zika virus is transmitted, to the name of the current president of France. A majority of the participants were unable to answer half of the questions correctly (Pew Research Center, 2017). While previous Pew knowledge surveys saw a majority of Americans answer only one quarter of the questions correctly (2014), it is clear that Americans today are still not completely up-to-date on current affairs. Along with Americans lacking knowledge of current affairs, the recent election saw the rise in accusations of "fake news." These calls inspired me to undertake my thesis project to try to answer the question: "does fake news actually impact the public's policy preferences, and if so, by how much?" While studies have been conducted to test the relationship between policy misperceptions and policy preferences, there have not been many studies released to directly test the impact of incorrect information on policy preferences. The underlying purpose of this study is to test how introduction of new information, particularly falsehoods, influences policy preferences. Specifically, I focus on policy preferences related to anthropogenic climate change . Any valid research that seeks to analyze the effect of political information on policy preferences needs to starts by discovering how much the public knows about the particular policy issue that the researcher is focusing on. Without explicitly saying as much, all of the research on the subject that I have read has come to the same conclusion: American's are indeed politically unaware on a wide array of issues. The areas of policy that Americans lack knowledge on are widespread: education (Howell and West, 2009), welfare (Gilens, 2001), the war in Iraq (Berinsky, 2007; Kull, 2003), and facts about political candidates (Nyhan and Reifler, 2012) are just some of the issues that Americans seem to know little about. Literature discussed in the following section shows how researchers have tried to understand how policy knowledge impacts policy opinions. Researchers primarily collected their data either one of two ways: by analyzing existing survey data or by conducting their own survey.

Description
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.

Description
There has been much work done predicting the effects of climate change on transportation systems, this research parallels that past work and focuses on the effect of changes in precipitation on roadway drainage systems. On a macro level, this work addresses the process that should be taken to make predictions about the vulnerability of this system due to changes in precipitation. This work also addresses the mechanisms of failure of these drainage systems and how they may be affected by changes in precipitation due to climate change. These changes may entail more frequent failure by certain mechanisms, or a shift in the mechanisms for particular infrastructure. A sample water basin in the urban environment of Phoenix, Arizona is given as a case study. This study looks at the mechanisms of failure of the infrastructure therein, as well as provides a process of analyzing the effects of increases in precipitation to the vulnerability of this infrastructure. It was found that drainage structures at roadways being currently designed will see increases from 20-30% in peak discharge, which will lead to increased frequency of failure.

Description
Observational evidence is mounting on the reduction of winter precipitation and an earlier snowmelt in the southwestern United States. It is unclear, however, how these changes, along with forest thinning, will impact water supplies due to complexities in the precipitation-streamflow transformation. In this study, I use the Triangulated Irregular Network-based Real-time Integrated Basin Simulator (tRIBS) to provide insight into the independent and combined effects of climate change and forest cover reduction on the hydrologic response in the Beaver Creek (~1100 km2) of central Arizona. Prior to these experiments, confidence in the hydrologic model is established using snow observations at two stations, two nested streamflow gauges, and estimates of spatially-distributed snow water equivalent over a long-term period (water years 2003-2018). Model forcings were prepared using station observations and radar rainfall estimates in combination with downscaling and bias correction techniques that account for the orographic controls on air temperature and precipitation. Model confidence building showed that tRIBS is able to capture well the variation in snow cover and streamflow during wet and dry years in the 16 year simulation period. The results from this study show that the climate change experiments increased average annual streamflow by 1.5% at +1°C of warming. However, a 28% decrease in streamflow occurs by +6°C of warming as evapotranspiration (ET) increases by 10%. Forest thinning shifted the warming threshold where ET increases reduce streamflow yield until +4°C of warming as compared to no forest thinning when this threshold occurs at +2°C. An average increase in streamflow of 12% occurs after forest thinning across all climate scenarios. While the snow covered area is unaffected by thinning, the volume of snowmelt increases and is linked to the higher water yield. These findings indicate that water managers can expect decreases in streamflow due to climate change but may be able to offset these impacts up to a warming threshold by thinning forested areas within the Beaver Creek.

Description
Accelerated climate and land use land cover (LULC) changes are anticipated to significantly impact water resources in the Colorado River Basin (CRB), a major freshwater source in the southwestern U.S. The need for actionable information from hydrologic research is growing rapidly, given considerable uncertainties. For instance, it is unclear if the predicted high degree of interannual precipitation variability across the basin could overwhelm the impacts of future warming and how this might vary in space. Climate change will also intensify forest disturbances (wildfire, mortality, thinning), which can significantly impact water resources. These impacts are not constrained, given findings of mixed post-disturbance hydrologic responses. Process-based models like the Variable Infiltration Capacity (VIC) platform can quantitatively predict hydrologic behaviors of these complex systems. However, barriers limit their effectiveness to inform decision making: (1) simulations generate enormous data volumes, (2) outputs are inaccessible to managers, and (3) modeling is not transparent. I designed a stakeholder engagement and VIC modeling process to overcome these challenges, and developed a web-based tool, VIC-Explorer, to “open the black box” of my efforts. Meteorological data was from downscaled historical (1950-2005) and future projections (2006-2099) of eight climate models that best represent climatology under low- and high- emissions. I used two modeling methods: (1) a “top-down” approach to assess an “envelope of hydrologic possibility” under the 16 climate futures; and (2) a “bottom-up” evaluation of hydrology in two climates from the ensemble representing “Hot/Dry” and “Warm/Wet” futures. For the latter assessment, I modified land cover using projections of a LULC model and applied more drastic forest disturbances. I consulted water managers to expand the legitimacy of the research. Results showed Far-Future (2066-2095) basin-wide mean annual streamflow decline (relative to 1976-2005; ensemble median trends of -5% to -25%), attributed to warming that diminished spring snowfall and melt and year-round increased soil evaporation from the Upper Basin, and overall precipitation declines in the Lower Basin. Forest disturbances partially offset warming effects (basin-wide mean annual streamflow up to 12% larger than without disturbance). Results are available via VIC-Explorer, which includes documentation and guided analyses to ensure findings are interpreted appropriately for decision-making.

Description
Climate change has necessitated the transition from non-renewable energy sources such as coal, oil, and natural gas to renewable, low-carbon energy sources such as solar, wind, and hydroelectric. These energy sources, although much better equipped to reduce carbon-induced climate change, require materials that pollute the environment when mined and can release toxic waste during processing and disposal. Critical minerals are used in low-carbon renewable energy, and they are subject to both the environmental issues that accompany regular mineral extraction as well as issues related to scarcity from geopolitical issues, trade policy, and geological rarity. Tellurium is a critical mineral produced primarily as a byproduct of copper and used in cadmium-telluride (CdTe) solar panels. As these solar panels become more common, the problems that arise with many critical minerals’ usage (pollution, unfair distribution, human health complications) become more apparent. Looking at these issues through an energy justice framework can help to ensure availability, sustainability, inter/intragenerational equity, and accountability, and this framework can provide a more nuanced understanding of the costs and the benefits that will accrue with the transition to low-carbon, renewable energy. Energy justice issues surrounding the extraction of critical minerals will become increasingly prevalent as more countries pledge to have a zero-carbon future.
