This thesis will examine possible connection points between the health of a local environmental/climate news ecosystem and that local community’s belief in and vulnerability to the effects of climate change in Central Appalachia and Northern Virginia. The three counties that will be studied in Virginia are Arlington, Buchanan and Wise Counties. This research will be mainly a hypothesis-generating descriptive analysis of data, coupled with both interviews with researchers and local experts, in addition to observations from relevant literature about the possible connections between availability of environmental news with climate change, institutional belief and climate vulnerability data. The local history of resource extraction will also be explored. The point of this thesis is not to prove that a lack of access to strong, locally focused climate and environmental news increases vulnerability to the effects of climate change (although it does raise this as a possibility). Rather, it is to continue a conversation with journalists, media professionals and climate professionals about how to approach understanding and engaging groups left out of the climate conversation and groups who've been traditionally underserved by news media when it comes to climate information and appeals for institutional trust. This conversation is already happening, especially when it comes to the importance of the health of local, community focused news in general in Appalachia, but given the urgency and scale of the climate crisis, merits continuation and some inquiry into environmental news.

With the rise of global warming and the growing energy crisis, scientists have pivoted from typical resources to look for new materials and technologies that can aid in advancing renewable energy efforts. Perovskite materials hold the potential for making high-efficiency, low-cost solar cells through solution processing of Earth abundant materials; however, scalability and manufacturability remain a challenge. In order to transition from small scale processing in inert environments via spin coating to higher throughput processing in ambient conditions via blade coating, the fundamentals of perovskite crystallization must be understood. Classical nucleation theory, the LaMer relation, and nonclassical crystallization considerations are discussed to provide a mechanism by which gellan gum, a nontoxic biopolymer from the food industry, has enabled quality halide perovskite thin films. Specifically, this research aims to study the effects of gellan gum in improving perovskite manufacturability by controlling crystallization through indirect alteration of evaporation and supersaturation rates by modifying fluid dynamics and the free energy associated with nucleation and growth. Simply, gellan gum controls crystallization to enable the fabrication of promising scalable PVSK devices in open air.

As projections of climate change effects in the media persist, current research suggests that threatening climate change content circulating social media and knowledge of threats to the Earth system and human health may lead to the development of eco-anxiety. If social media exposure to climate change content influences eco-anxiety, there is a need for psychological interventions to help manage climate change-related negative affect. A systematic review was conducted 1) to investigate the relationship between the use of social media and eco-anxiety in young adults and 2) to explore methodological factors involved in eco-anxiety research, including measurements and potential moderating factors. The review included seventeen articles that studied the measurements of eco-anxiety, the relationship between social media and eco-anxiety, or negative affect related to climate change and potentially moderating risk factors. A thematic analysis of the included articles yielded four central themes: (1) The Operationalization of Eco-anxiety, (2) Climate Change Perceptions and their Effects on Impairments, (3) The Relationship between Social Media Usage and Eco-anxiety, and (4) Potential Factors Influencing Climate Change Perceptions. The results suggest that eco-anxiety is real and common, especially amongst young people, and that it may be reliably measured using the Climate Change Anxiety Scale. Due to the limited and heterogeneous literature on the problem, no definitive conclusions can be drawn about how potential factors influence eco-anxiety. Future research should further explore the relationship between social media and eco-anxiety. In addition, the problem of eco-anxiety should be studied in underrepresented, vulnerable populations at higher risk for weather-related events.
