Understanding the factors that shape individuals beliefs about climate change is key to the development of effective climate change communication and education strategies. In this study, we test a path model of the social psychological antecedents of beliefs about climate change and evaluate the effectiveness of an educational travel program in changing them. Results show that environmental worldview and affective association with nature are two significant predictors of students belief in the occurrence of climate change. Gender was found to influence belief in an anthropogenic causation, while political orientation was a significant predictor of conviction that climate change is occurring. Regression analysis was used to test for changes in climate beliefs before and after participation in an educational travel experience, compared to a control group, using a quasi-experimental design. Results indicate participation strengthened climate change beliefs. 2019, 2019 Informa UK Limited, trading as Taylor & Francis Group.
