摘要

Despite growing recognition of climate change and its increasingly localized impacts, relatively little research has examined how local media, particularly opinion journalism, cover this critical issue. This study analyzes 15,788 opinion articles published from 2013 to 2020 by 391 local newspapers in the United States, focusing on changes in volume, topics, and thematic emphases over time. Using automated text analysis methods, including Latent Dirichlet Allocation (LDA) and Analysis of Topic Model Networks (ANTMN), the study identifies 11 topics that cluster into three overarching themes. Findings indicate that coverage has evolved over time, likely in response to the severity of climate-induced hazards and political and shifting socioeconomic contexts. Notably, there has been a transition from ideological and policy-level discourse to more community-centered narratives that stress local climate action and adaptation. This study contributes to the growing field of climate journalism and offers practical implications for policymakers and media practitioners. Limitations are acknowledged, along with directions for future research.
