标题： Transitions in climate and energy discourse between Hurricanes Katrina and Sandy

摘要： 尽管气候变化和能源密切相关，但它们之间的明确联系在公众讨论和媒体中并不总是显而易见的。 破坏性的极端天气事件，包括飓风，以新的和不同的方式吸引公众的关注，为分析聚焦事件如何影响公众讨论提供了一个独特的契机。 极端天气事件的媒体报道同时塑造并反映了关于气候变化问题的公众讨论。 在这里，我们使用主题模型分析飓风卡特里娜（2005年）和桑迪（2012年）期间的气候和能源报纸报道，主题模型是一种用于在一组文档中发现抽象主题的数学技术。 我们的结果表明，卡特里娜飓风后的媒体报道中没有包含气候变化主题，能源主题仅限于对能源价格、市场和经济的讨论，几乎没有任何明确的能源与气候变化之间的联系。 相比之下，桑迪飓风后的媒体报道确实包含一个显著的气候变化主题、一个独立的能源主题，以及气候变化和能源的综合表述，表明在卡特里娜飓风和桑迪飓风之间，气候变化和能源报道发生了转变。 显示英文摘要

摘要： Although climate change and energy are intricately linked, their explicit connection is not always prominent in public discourse and the media. Disruptive extreme weather events, including hurricanes, focus public attention in new and different ways, offering a unique window of opportunity to analyze how a focusing event influences public discourse. Media coverage of extreme weather events simultaneously shapes and reflects public discourse on climate issues. Here we analyze climate and energy newspaper coverage of Hurricanes Katrina (2005) and Sandy (2012) using topic models, mathematical techniques used to discover abstract topics within a set of documents. Our results demonstrate that post-Katrina media coverage does not contain a climate change topic, and the energy topic is limited to discussion of energy prices, markets, and the economy with almost no explicit linkages made between energy and climate change. In contrast, post-Sandy media coverage does contain a prominent climate change topic, a distinct energy topic, as well as integrated representation of climate change and energy, indicating a shift in climate and energy reporting between Hurricane Katrina and Hurricane Sandy.
