Research on the gateway belief model indicates that communicating the scientific consensus on global warming acts as a “gateway” to other beliefs and support for action. We test whether a video conveying the scientific consensus on global warming is more effective than a text transcript with the same information. Results show that the video was significantly more effective than the transcript in increasing people’s perception of scientific agreement. Structural equation models indicate indirect increases in the beliefs that global warming is happening and is human-caused, and in worry about global warming, which in turn predict increased global warming issue priority.

共识的经验：视频作为传播气候变化科学协议的有效媒介

对门户信念模型的研究表明，传播关于全球变暖的科学共识是通向其他信念和支持行动的“门户”。我们测试传达有关全球变暖的科学共识的视频是否比具有相同信息的文本更有效。结果表明，在增加人们对科学一致性的看法方面，视频明显比文字稿更有效。结构方程模型表明全球变暖正在发生并且是人为原因的信念的间接增加，以及对全球变暖的担忧，这反过来预测全球变暖问题的优先级增加。
