AI 中文总结

AI 中文摘要
气候运动通常通过关注度和动员程度来评估，但对其伴随的幸福感语言知之甚少。运动时期是否会改变积极情感和希望，以及幸福感是否与行动语言一致，仍未得到解答。我们分析了地球日、地球一小时、全球气候行动日和世界环境日在19个发生年份中的364,118条公开Twitter/X帖子，使用事件前30天、事件期间和事件后30天的时间窗口。一个版本化的加权词汇模型估计了幸福感、未来导向的希望、集体能力、困扰和行动语言。事件期间的幸福感流行率比事件前基线高出9.02个百分点，而配对发生对比显示行动语言下降了10.75个百分点，表明存在幸福感与行动的背离。幸福感估计在构成和文本去重检查中保持正值，但在19簇野自助法下精度较低。更幸福的源帖子观察到匹配的转发级联的几率更低。
英文摘要
Climate campaigns are often evaluated through attention and mobilization, but less is known about the well-being language that accompanies them. Whether campaign periods alter positive affect and hope, and whether happiness aligns with action language, remains unresolved. We analysed 364,118 public Twitter/X posts from Earth Day, Earth Hour, Global Climate Action Day and World Environment Day in 19 occurrence-years, using 30-day pre-event, event and post-event windows. A versioned weighted lexical model estimated happiness, future-oriented hope, collective capability, distress and action language. Event-period happiness prevalence was 9.02 percentage points higher than the pre-event baseline , whereas paired occurrence contrasts showed a 10.75-point decline in action language, indicating a happiness--action divergence. The happiness estimate remained positive across composition and text-deduplication checks, but was less precise under a 19-cluster wild bootstrap. Happier source posts had lower odds of an observed matched retweet cascade.
