The role of media in conflicts and dilemmas arising from the contested status of facts and truths in science, climate change, and the environment cannot be overstated. Across a multiplicity of different media outlets, from journalistic sources to digital platforms, this anthology examines various representations of factuality. This covers topics such as mis-and disinformation, conspiracy theories, and counter-knowledge representations on the one hand, over to authorities and other political actors’ use of more mainstream media outlets to either build public trust or to discuss and contest authoritative scientific discourses on the other. This introduction positions the individual studies in the chapters within a constructivist and discursive framework. Science, climate change, and environment conflicts therefore consist of a number of different discursively constructed positions competing for attention in the public media spheres; some reflect expert discourse while others draw on more popular science positions which are explicitly political.
