Climate change threatens individuals, communities, nations, and the world, and each of these must take action to mitigate and adapt to climate change. Because climate change requires action at all these levels, public engagement with the issue of climate change is necessary. In this research, I describe three investigations of communication about climate change. Across these projects, I attend to the specific type of strategies to address climate change being considered (e.g., adaptation, mitigation), the context and positionality of the messenger and audience, and the psychological characteristics which influence responses to and methods of climate change communication. . In Chapter 2, the effectiveness of climate change art as a means of communicating climate risks and solutions was evaluated. This research sought to identify which method of sharing art is most effective, and whether climate change art has advantages over other forms of communication. Viewing climate change art increased risk perceptions, sense of personal responsibility to address climate change, and other proenvironmental attitudes. Chapter 3 provides the description of research on the preferences of the U.S. public for coastal community adaptation. These studies compared preferences different kinds of strategies in different kinds of communities, to understand what psychological, community, and strategy characteristics predict support for coastal adaptation. Participants generally supported implementation of these adaptation strategies, but preferences varied depending on the type of community described (e.g., high vs. low risk) and the participant’s characteristics (e.g., political ideology). Chapter 4 was an investigation of elite communication of climate change, seeking to understand how leaders have historically communicated about climate change, and how differences in their positionality predict such communication, using computational text analysis. Trends in sentiment over time were detected, and delegates’ country characteristics including wealth and development status influenced sentiment expression. In the final chapter, the implications of these three investigations are discussed, and future directions which draw on the findings and methodology of the current investigations are proposed.
