Social media is a transformative digital technology, collapsing the “six degrees ofseparation” which have previously characterized many social networks, and breaking down many of the barriers to individuals communicating with each other. Some commentators suggest that this is having profound effects across society, that social media have opened up new channels for public debates and have revolutionized the communication of prominent public issues such as climate change. In this article we provide the first systematic and critical review of the literature on social media and climate change. We highlight three key findings from the literature: a substantial bias toward Twitter studies, the prevalent approaches to researching climate change on social media (publics, themes, and professional communication), and important empirical findings (the use of mainstream information sources, discussions of “settled science,” polarization, and responses to temperature anomalies).Following this, we identify gaps in the existing literature that should beaddressed by future research: namely, researchers should consider qualitativestudies, visual communication and alternative social media platforms to Twitter.We conclude by arguing for further research that goes beyond a focus on sciencecommunication to a deeper examination of how publics imagine climate changeand its future role in social life.

In the 1990s, the popularisation of house music and ecstasy led to a shift in the focus of research into club cultures. Characteristic of club culture is the willingness to share on the social (network), cultural (taste and knowledge), and physical (location) levels. Drug researchers ascertain that, since the 1990s, there has been a normalisation of drug use in the entertainment areas of youth and young adults. In an ongoing panel study among Amsterdam’s trendsetters, club cultures prove eminently receptive to new trends in nightlife. This chapter focuses on the transformation of club cultures into screen cultures within the electronic dance music (EDM) domain and the influence of vernacular media. This development runs parallel to the flight from overregulated entertainment venues. A second development is that the growing influence of the vernacular media has stimulated and also democratised knowledge, opinions and discussions about drugs, and the role in the prevention and risk discourse has changed from of a top-down to a linear model. In the vernacular discourse, the dominating view is that it is normal to experiment with drugs as long as it is done responsibly.

Studying images in social media poses specific methodological challenges, which in turn have directed scholarly attention toward the computational interpretation of visual data. When analyzing large numbers of images, both traditional content analysis as well as cultural analytics have proven valuable. However, these techniques do not take into account the contextualization of images within a socio-technical environment. As the meaning of social media images is co-created by online publics, bound through networked practices, these visuals should be analyzed on the level of their networked contextualization. Although machine vision is increasingly adept at recognizing faces and features, its performance in grasping the meaning of social media images remains limited. Combining automated analyses of images with platform data opens up the possibility to study images in the context of their resonance within and across online discursive spaces. This article explores the capacities of hashtags and retweet counts to complement the automated assessment of social media images, doing justice to both the visual elements of an image and the contextual elements encoded through the hashtag practices of networked publics.
