Parallel routes from Copenhagen to Paris: climate discourse in climate sceptic and climate activist blogs

The Copenhagen climate summit in 2009 was a watershed moment in the international climate change discourse, reinforcing controversy and polarization between climate sceptics and climate activists. Simultaneously, the blogosphere, known as a place for polarized mobilization, became a proliferating forum for both camps. Building on Dryzek’s and Carvalho’s conceptualization of environmental discourse, this paper analyses how ideological polarization is grounded in climate sceptics’ and climate activists’ blogs between COP15 and COP21. We investigated ten climate sceptic and climate activist blogs accessible in the UK. Qualitative-quantitative analysis of 357 blog posts revealed contrasting ontological and epistemological worlds in the climate change controversy. Four storylines were identified in the climate sceptical discourse–‘hoax’, ‘no scientific evidence’, ‘climate sceptical science’, and ‘injustice’–and five storylines in the climate activist discourse–‘action’, ‘social justice’, ‘disaster strikes’, ‘potential catastrophe’, and ‘opportunity’. Implications for policy, practice and future research are provided.
