The Internet has helped to change who writes about science in the news, how news is written, and how it is taken up by different audiences. However, few studies have examined how these changes have impacted the uptake of scientific claims in online news writing. This case study explores how online news genres take up knowledge claims from a research article on climate change over a period of one year and shows how shifting boundaries between rhetorical communities affect genre uptake. The study results show that online news writers predominantly use the news report genre to cover research findings for 48 hours, after which they predominantly use the news editorial genre to engage these findings. Analysis suggests that the news report genre uses the press release and the article abstract as intermediary genres, but the news editorial uses only the abstract. I argue that the switch between genres repositions the scientist, the journalist, and the public epistemologically, a reorientation that favors uptake in news media outlets supporting action to mitigate climate change and its effects.

在线新闻类型如何处理有关气候变化的科学研究文章中的知识主张？

互联网已经帮助改变了谁在新闻中撰写关于科学的文章，新闻的撰写方式以及新闻被不同受众所接受的方式。但是，很少有研究检查这些变化如何影响在线新闻写作中对科学主张的接受。本案例研究探讨了在线新闻类型如何处理一年期间有关气候变化的研究文章中的知识主张，并展示了修辞社区之间不断变化的边界如何影响类型吸收。研究结果表明，在线新闻撰稿人主要使用新闻报道体裁来报道48个小时的研究发现，然后主要使用新闻社论体来吸引这些发现。分析表明，新闻报道类型使用新闻稿和文章摘要作为中介类型，但是新闻社论只使用摘要。我认为，体裁之间的转换在认识论上重新定位了科学家，新闻工作者和公众，这种重新定位有利于支持支持减轻气候变化及其影响的行动的新闻媒体的采用。
