Climate Change on Twitter: Topics, Communities and Conversations about the 2013 IPCC Working Group 1 Report

Abstract

In September 2013 the Intergovernmental Panel on Climate Change published its Working Group 1 report, the first comprehensive assessment of physical climate science in six years, constituting a critical event in the societal debate about climate change. This paper analyses the nature of this debate in one public forum: Twitter. Using statistical methods, tweets were analyzed to discover the hashtags used when people tweeted about the IPCC report, and how Twitter users formed communities around their conversational connections. In short, the paper presents the topics and tweeters at this particular moment in the climate debate. The most used hashtags related to themes of science, geographical location and social issues connected to climate change. Particularly noteworthy were tweets connected to Australian politics, US politics, geoengineering and fracking. Three communities of Twitter users were identified. Researcher coding of Twitter users showed how these varied according to geographical location and whether users were supportive, unsupportive or neutral in their tweets about the IPCC. Overall, users were most likely to converse with users holding similar views. However, qualitative analysis suggested the emergence of a community of Twitter users, predominantly based in the UK, where greater interaction between contrasting views took place. This analysis also illustrated the presence of a campaign by the non-governmental organization Avaaz, aimed at increasing media coverage of the IPCC report.

Examining User Comments for Deliberative Democracy: A Corpus-driven Analysis of the Climate Change Debate Online

“…This idea has also been understood in relation to "selective exposure," a practice in which users seek opinionreinforcing content or demonstrate "challenge-aversion" which is seen as problematic and an "anathema to the deliberative perspective" (Freelon, 2013, p. 5;Sunstein, 2009). This idea is supported by Pearce, Holmberg, Hellsten, and Nerlich (2014), who found that Twitter users are more likely to make conversational connections with those who have broadly similar views. There is, however, a possibility that a larger "argument repertoire" increases ambivalence amongst participants.…”

Visual cross-platform analysis: digital methods to research social media images

“…Marres (2017, p. 123) identifies three issues in digital bias (at a minimum) requiring attention: (1) bias in the selected data and content, as the researcher selects certain snapshots of social media coverage; (2) built-in software bias in the research instruments, for example, bias through embedded algorithms; and (3) bias of methodological nature, for example, social media research tools are more amenable to textual queries than visual queries, resulting in a bias towards textual analysis that provides only partial analysis of platform content. Marres calls for an 'affirmative approach' to digital bias (2017, p. 125); that is, accepting these biases as part of the object of study rather than attempting to neutralise platform effects by disentangling medium research from social research (Pearce, Holmberg, Hellsten, & Nerlich, 2014).…”

As mudanças climáticas no Twitter: a ascendência da mídia e da política

“…Sabe-se que a realização de eventos internacionais, as agendas intergovernamentais, as publicações de lideranças políticas e/ou pessoas famosas e os eventos meteorológicos extremos proporcionam um aumento nas abordagens não só na mídia tradicional como também nas referências ao tema nas redes sociais (Kirilenko & Stepchenkova, 2014;Pearce et al, 2014;Cody et al, 2015). está acontecendo?".…”

“…A preferência pelo uso de hashtag vai ao encontro do que muitos autores referem sobre a formação de "comunidades" ao utilizarem-se termos em comum (e.g. Segerberg & Bennett, 2011;Pearce et al, 2014;Williams et al, 2015). Identifica-se também que do total de publicações que utilizaram o termo "COP21" na língua espanhola, menos de um terço dos tweets é de texto original, sendo a maior parte partilha via RT.…”
