The emergence and popularity of mobile and social media have transformed the nature of the parasocial relationship between weathercaster and audience. Two experts and nine television viewers were selected for qualitative interviewing via non-probability sampling to gain an understanding of how respondents’ growing use of social media and other emerging media has impacted the relationship with the local television weathercaster. Additionally, these interviews explored the ways in which these relationships have ultimately changed how viewers receive weather warnings. Storms producing strong straight-line winds and multiple tornadoes in the Fort Wayne, Indiana television market provided a case study that illuminated the role of trust in the complex relationships between weather forecasting and new social media. Mobile and social media have increased the weather forecasters’ influence over the audience, while quickly allowing them to provide severe weather warnings. This study demonstrates the popularity of social media among diverse age groups and that user demographics do not indicate any level of social media literacy. Second, as the literature suggests, this study confirms users’ trust in their weather forecasters as well as the informationseeking behavior displayed during severe weather. Third, this research finds that social media has transformed parasocial relationships. Finally, this study suggests that stations have not recognized nor taken advantage of these new parasocial relationships, and that they can do so by promoting TV personalities’ online social profiles. / Introduction -- Literature review -- Methods -- Trust, weather forecasting and social media -- Online presence -- Conclusion. / Department of Geography

The phenomenon of climate change exists in a liminal state between denial and acceptance, past and future, theory and reality, problem and catastrophe, unfolding in the spaces between apparently stable forms. This thesis considers different temporalities emerging within this transition through a creative exploration of extreme weather and climatic events that seeks to foreground the idea of change itself. Research centers around the Florida Keys, a low lying archipelago that is widely expected to become uninhabitable in the next half century due to sea level rise, but only if the islands do not suffer a similar fate much sooner with the sudden arrival of a catastrophic hurricane. While most Keys residents are unconcerned about the growing reality of sea level rise, hurricanes are a constant threat generating a palpable atmosphere of anticipation and corresponding precaution. In resonance with this regular storm activity in the Florida Keys, the project also reflects on the coincidental occurrence of Hurricanes Irene (2011) and Sandy (2012), two errant and devastating storms that visited the northeastern United States over the course of this project and personally affected the author. Thus, extreme weather provides a material entry point into the complex and far-reaching event of climate change, offering an opportunity to theorize transition and to reflect on what might be creatively recuperated from cross currents of climate and catastrophe. In conclusion, the thesis proposes an ontology inspired by the unique reproductive strategy of the mangrove plant that has thickly and extensively colonized the coastline of southern Florida and through which events are understood to possess qualities of latency, accrual and distribution and to give rise to a future that is germinal, a present that is continuously resignified and a past that remains profoundly creative.
