Anthropogenic climate change (global warming) is considered the most excruciating risk that threatens human sustainability in the twenty first century. Traditional and internet digital media (new media) play pivotal roles to educate and enlighten the public on this irreversible ongoing crisis. As a leading video-sharing webcasting and global streaming social medium, YouTube is renowned for acting as a popular science provider and climate science educator on climate change and global warming crisis. The current study employs methods of content analysis and narrative analysis to examine the most viewed, liked, and subscribed climate crisis videos on YouTube to study the narrative themes, narrative structure and meanings as well as their contextual backgrounds.
