当地电视（TV）天气预报员是气候教育的潜在有前途的来源，因为天气是观众观看当地电视新闻的主要原因，大部分公众信任电视天气预报员作为关于全球变暖的信息来源，并且极端天气事件越来越常见（Leiserowitz等人;美国全球变化研究计划（Global Change Research Program）。在两个南卡罗来纳州城市（格林维尔，n = 394;哥伦比亚，n = 352）在夏季热浪期间和之后立即进行的在线实验中，对全球变暖风险感知的影响进行了检查，暴露于电视天气预报后，天气预报员将热浪解释为全球变暖的局部表现，而不是暴露于72小时的极端高温预报。没有发现全球变暖视频对学习的主要影响，但是发现了一个显著的交互效应：对电视天气预报员评价更积极的被试受到全球变暖视频的积极影响，而对天气预报员评价不太积极的观众受到视频的消极影响。这种影响在政治保守派观众中最为强烈。这些结果表明，天气预报员提供的气候变化教育可以对电视观众产生积极的，尽管是细微的影响。
Local television (TV) weathercasters are a potentially promising source of climate education, in that weather is the primary reason viewers watch local TV news, large segments of the public trust TV weathercasters as a source of information about global warming, and extreme weather events are increasingly common (Leiserowitz et al.; U.S. Global Change Research Program). In an online experiment conducted in two South Carolina cities (Greenville, n = 394; Columbia, n = 352) during and immediately after a summer heat wave, the effects on global warming risk perceptions were examined following exposure to a TV weathercast in which a weathercaster explained the heat wave as a local manifestation of global warming versus exposure to a 72-h forecast of extreme heat. No main effect of the global warming video on learning was found. However, a significant interaction effect was found: subjects who evaluated the TV weathercaster more positively were positively influenced by the global warming video, and viewers who evaluated the weathercaster less positively were negatively influenced by the video. This effect was strongest among politically conservative viewers. These results suggest that weathercaster-delivered climate change education can have positive, albeit nuanced, effects on TV-viewing audiences.
