Reason and rhetoric in climate communication

Rhetoric can facilitate movement beyond impasse on whether and how to confront climate change, enabling more effective public reasoning. Our evidence comes from a small deliberative group that contained climate-change deniers. We show how, in this setting, bridging rhetoric (capable of reaching those who do not share the speaker’s perspective) managed to bring deniers and others into accepting that particular greenhouse-gas mitigation measures were in the range of acceptable policy choices – even as deniers continued to dispute the existence of anthropogenic climate change. What we observed drives home the need for rhetorical bridges in broader public debates on climate change.
