Determinants of climate change risk perception in Latin America.

Climate change risk perceptions are subjective constructs that individuals use to interpret the potential harms of climate change and influence their engagement in mitigation and adaptation efforts. While research in high-income Western countries has identified cognitive processes, socio-cultural factors, and political ideology as key predictors of climate risk perceptions, their applicability to low- and middle-income regions remains uncertain. This study uses a cross-national survey conducted in Argentina, Brazil, Colombia, Chile, Ecuador, Peru, and Mexico (N = 5338) to assess climate risk perceptions in Latin America. We show that emotional responses, especially worry and perceived vulnerability to extreme weather, are the strongest predictors. In contrast, political ideology and socio-demographic factors exhibit weak and inconsistent associations, diverging from patterns observed in high-income countries. These findings highlight that climate change is not perceived as a politically divisive issue in the region, suggesting opportunities for cross-party collaboration on climate initiatives. Understanding these unique drivers in regions with emerging economies is crucial for developing effective, tailored risk communication strategies.
