I will be presenting research, co-authored with Luis Hestres (University of Texas at San Antonio), at the 2017 conference of the Association for Education in Journalism and Mass Communication (AEJMC) in Chicago August 10. Research summary: The past two decades have transformed the ways political groups and individuals engage in collective action. Meanwhile, the climate change advocacy landscape, previously dominated by well-established environmental organizations, now accommodates new ones focused exclusively on this issue. This article examines the convergence of these trends through the examples of 350.org, the Climate Reality Project, and The Guardian’s “Keep It in The Ground” campaign. Implications for the future of Internet-mediated climate advocacy are discussed.
