Public communication represents a vital civic function for governments developing climate policies, particularly with vulnerable communities under environmental justice mandates. In this study, three videos developed to support a state’s climate change public engagement are used to evaluate how governmental communication using the frames of health, science, and local effects influences two theoretically important constructs, risk perception and collective efficacy. Vulnerable audiences differentiated by stress, perceived lack of control, and poor health demonstrate significant gains in collective efficacy relative to risk—“danger control” —after the intervention. But we find no differences between the three frames in their effects on perceptions of climate change risk and collective efficacy.

政府对气候变化风险和效力的沟通：将受众推向“危险控制”

公共交流是政府制定气候政策的一项重要公民职能，特别是与受环境正义授权的弱势社区。在这项研究中，为支持一个州的气候变化公众参与而开发的三个视频被用来评估使用健康、科学和地方影响框架的政府沟通如何影响两个理论上重要的结构，风险感知和集体效能。因压力、感知到的缺乏控制和健康状况不佳而区分的弱势受众在干预后表现出相对于风险的集体效能的显着提高——“危险控制”。但是我们发现这三个框架对气候变化风险和集体效能的看法的影响没有差异。
