This working paper preserves all contributions to the "Media Watchblog" as they appeared during the UN climate conference in Paris 2015 (and as they are still available at https://climatematters.blogs.uni-hamburg.de/media-watch-blog/all-articles/). The idea of the Media Watch Blog was to provide space for presenting an analytical view of the media coverage and the debates surrounding COP 21 through the lens of academic observers from social and climate sciences, and allowing for comments in our role as citizens that we would not include in our academic publications. The point of the blog is not to bash the media: Covering climate change is a demanding challenge for journalists and we do not pretend that we could do better than journalists do. Yet, as outside observers of the debate, we hope to add new perspectives to a debate that deserves humanity’s most alert attention. The blog is at the University of Hamburg. Going beyond Hamburg, its authors are climate researchers, social scientists and also some journalists from a range of different backgrounds united by an interest in the interdisciplinary study of climate change.
