An analysis of the differences and commonalities between climate sceptic and climate optimist discourse as found in YouTube videos

Climate optimism is a discourse that constructs climate change as a serious issue that is solvable by humanity, while climate sceptic discourse constructs a world in which climate change is a negligible issue. Filling research gaps such as climate change discourse in YouTube videos and comparative discourse analysis on climate change, this study looks at the similarities and differences between climate optimist and climate sceptic discourse. It finds both similarities and differences in how they construct their worlds, and makes recommendations for future studies and climate change communications based on the results.
