Global warming will disproportionately affect people of color (e.g., Latinos). Previous research has found that Latinos in the USA are more engaged with global warming than are non-Latino Whites, in part, because they are more likely to perceive it as a serious risk. It was unclear, however, what factors most strongly explain Latinos’ elevated perceptions of risk. This study uses two parallel, nationally representative surveys of Latino and non-Latino White Americans to investigate these different levels of risk perception. Mediation analyses indicate that Latinos’ greater risk perceptions may be explained by (in order of magnitude) their stronger pro-climate injunctive social norms and egalitarian worldviews, stronger identification with the Democratic party, more frequent communication with family outside the USA, greater harm from environmental hazards, stronger descriptive norms, and a weaker individualist worldview. These findings help inform strategies for communicating with different subgroups of Americans that have different global warming risk perceptions.

拉丁裔和非拉丁裔美国白人对全球变暖风险认知的预测因素

全球变暖将对有色人种（例如拉丁裔）产生不成比例的影响。先前的研究发现，与非拉丁裔白人相比，美国的拉丁裔美国人更关注全球变暖，部分原因是他们更有可能将其视为严重风险。然而，目前尚不清楚哪些因素最能解释拉丁美洲人对风险的高认识。本研究使用两项平行的、具有全国代表性的拉丁裔和非拉丁裔美国白人调查来调查这些不同水平的风险感知。调解分析表明，拉丁美洲人的更大风险认知可能是由于（按数量级排序）他们更强烈的支持气候的禁令社会规范和平等主义的世界观，对民主党的认同感更强，与美国以外的家人更频繁的交流，环境危害造成的危害更大，描述性规范更强，个人主义世界观更弱。这些发现有助于为与具有不同全球变暖风险认知的不同美国人亚群交流的策略提供信息。
