Twitter enables an online public sphere for social movement actors, news organizations, and others to frame climate change and the climate movement. In this paper, we analyze five million English tweets posted from 2018 to 2021 demonstrating how peaks in Twitter activity relate to key events and how the framing of the climate strike discourse has evolved over the past three years. We also collected over 30,000 news articles from major news sources in English-speaking countries (Australia, Canada, United States, United Kingdom) to demonstrate how climate movement actors and media differ in their framing of this issue, attention to policy solutions, attribution of blame, and efforts to mobilize citizens to act on this issue. News outlets tend to report on global politicians’ (in)action toward climate policy, the consequences of climate change, and industry's response to the climate crisis. Differently, climate movement actors on Twitter advocate for political actions and policy changes as well as addressing the social justice issues surrounding climate change. We also revealed that conversations around the climate movement on Twitter are highly politicized, with a substantial number of tweets targeting politicians, partisans, and country actors. These findings contribute to our understanding of how people use social media to frame political issues and collective action, in comparison to the traditional mainstream news outlets.

Twitter 为社会运动参与者、新闻机构和其他人提供了一个在线公共领域来构建气候变化和气候运动。在本文中，我们分析了从 2018 年到 2021 年发布的 500 万条英文推文，展示了 Twitter 活动的高峰与关键事件之间的关系，以及气候罢工话语的框架在过去三年中是如何演变的。我们还收集了来自英语国家（澳大利亚、加拿大、美国、英国）的主要新闻来源的 30,000 多篇新闻文章，以展示气候运动参与者和媒体在对该问题的框架、对政策解决方案的关注、对责备，并努力动员公民在这个问题上采取行动。新闻媒体倾向于报道全球政客对气候政策的（不）行动、气候变化的后果、以及行业对气候危机的反应。不同的是，Twitter 上的气候运动参与者倡导政治行动和政策变革，以及解决围绕气候变化的社会正义问题。我们还透露，Twitter 上围绕气候运动的对话高度政治化，有大量针对政客、游击队和国家行动者的推文。与传统的主流新闻媒体相比，这些发现有助于我们了解人们如何使用社交媒体来构建政治问题和集体行动。我们还透露，Twitter 上围绕气候运动的对话高度政治化，有大量针对政客、游击队和国家行动者的推文。与传统的主流新闻媒体相比，这些发现有助于我们了解人们如何使用社交媒体来构建政治问题和集体行动。我们还透露，Twitter 上围绕气候运动的对话高度政治化，有大量针对政客、游击队和国家行动者的推文。与传统的主流新闻媒体相比，这些发现有助于我们了解人们如何使用社交媒体来构建政治问题和集体行动。
