This corpus-based study investigates the contested discursive processes surrounding climate change knowledge in the blogosphere. Unlike previous research focusing on mainstream media, this paper analyzes blog posts from scientists, journalists, researchers, and lobbyists, representing diverse perspectives beyond the "alarmist vs. denier" dichotomy. Using a systemic functional linguistic approach, the study examines bloggers' use of "bias," "dogma," and "peer review" to reveal their reliance on epistemic and non-epistemic values. Concordances and visualization tools provide insights into lexical choices and how bloggers construct authorial subjectivities to claim expert status and challenge the recognition of others.
