Shades of denialism: discovering possibilities for a more nuanced deliberation about climate change in online discussion forums

This article explores rhetorical practices underlying productive deliberation about climate change. We analyze discussion of climate change on a Reddit subforum to demonstrate that good-faith deliberation---which is essential to deliberative democracy---exists online. Four rhetorical concepts describe variation among this subforum's comments: William Keith's distinction between 'discussion' and 'debate,' William Covino's distinction between good and bad magic, Kelly Oliver's notion of ethical response/ability, and Krista Ratcliffe's notion of rhetorical listening. Using a three-part taxonomy based on these concepts, we argue that collaborative climate change deliberation exists and that forum participation guidelines can promote productive styles of engagement.
