本研究以TVBS【搶救地球】特別報導為例，探究電視新聞專題如何使用口語、圖／影像、音樂等多媒材呈現全球暖化故事。七則個案雖仰賴口語媒材指出暖化問題、介紹防治行動及科學發現，但在型塑環境美景與提供行動理由上卻以影像為主而音樂或口語為輔。報導環境人為破壞則常以人類「導因畫面」與口語相互補充或以黑白畫面暗示負面影響，而局部矛盾的媒材意義可能從整體口語敘事脈絡獲得連貫性進而強化敘事意涵。

Television news is a valuable means by which the public gains access to information on global warming. Based on a case study of Rescue Earth, this study investigated the modes by which television (TV) news reports on global warming. Oral narratives dominate TV news coverage, particularly in defining global warming as a crisis, introducing prevention strategies, and explaining scientific information. However, musical and oral narratives are usually used for amplifying the meaning conveyed by images in order to construct an image of a beautiful and pristine environment worthy of being protected. In addition, accounts of people-caused global warming are relayed through oral narratives, and black-and-white visuals are used to imply negative effects. Although images contradict the verbal message locally, they might acquire coherence from audio narration globally.
