The Mapping Climate Communication project offers an overview of how climate change is communicated in the public realm by visualizing actors, events, strategies, media coverage and discourses influencing public opinion. Two large-scale maps and one Poster Summary Report were published on-line October 2014. The project uses two visualization methods: a timeline and a network visualization. The Climate Timeline (CT) visualizes the historical processes and events that have lead to the growth of various ways of communicating climate change. The Network of Actors (NoA) illustrates relationships between institutions, organizations and individuals participating in climate communication in Canada, United States and the United Kingdom. Together these two visualizations contextualize events and actors within five discourses: climate science, climate justice, ecological modernization, neoliberalism and climate contrarianism. Since communication happens at the level of rhetoric as well as the level of action, discourses in this project include explicit messages and also messages that are implicit within political, corporate and organizational activities and policy. This approach reveals tensions and contradictions in climate communication.
