FOCI’s Work Package on ‘Perceptions of Climate Change and Social Futures’ examines the multiple, and potentially divergent, social perceptions of climate change among the public, experts, media, and policy network actors across Atlantic Canada. It analyses social perceptions of climate change and builds social infrastructure by assessing: i) regional impacts of climate change, ii) responses, in terms of mitigation and adaption; and iii) capacity to respond to changes. Improving our understanding of the social perceptions of climate change in these different spheres helps innovate governance infrastructures that can better navigate futures of climate change and social-ecological instability. The overall objective is to build citizen engagement and policy network infrastructure to help communities grapple with climate change and rapidly evolving ecosystems.
