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.
