Abstract: This study investigated whether increased technological affordances, characterized by the rise of social media, diversified communication in climate change discourse. Extending the literature of intermedia agenda setting, this study examined agenda and frame contagion across Twitter and online news media. Using a large dataset of media content about climate change, time-series analysis showed that news media played a major role in setting agendas and frames, but Twitter has increased its dominance in climate change discussions. The findings address both opportunities for strategic science communication and challenges resulting from unverified scientific claims (e.g., hoax frames) spread on social media.
文摘：本研究调查了以社交媒体崛起为特征的技术赋能提升，是否使气候变化话语中的传播呈现多样化。本研究扩展了中间媒介议程设置的相关文献，考察了Twitter与网络新闻媒体之间的议程及框架传染。通过使用关于气候变化的大规模媒体内容数据集，时间序列分析表明，新闻媒体在设置议程和框架方面发挥了主要作用，但Twitter在气候变化讨论中的主导地位有所增强。研究结果既探讨了战略性科学传播的机遇，也应对了社交媒体上散布的未经证实的科学主张（如“骗局”框架）所带来的挑战。
