This document analyzes social media discourse around two climate events: the COP20 climate conference in Lima and the People's Climate March. It finds that:
1) The climate change narrative occurs mostly within an "echo chamber" or "bubble" of environmental organizations and activists, with limited traction beyond this group.
2) Celebrities and media outlets generate the most engagement on Facebook, while Twitter discourse is dominated by environmental non-profits and activists.
3) The researchers conclude the narrative needs to better engage users on each platform rather than just imposing messaging, in order to expand its reach outside the "bubble."
