Climate Change Conspiracy Beliefs: Associations with Public Perceptions, Policy Support, and Emotional Engagement.

We collected data from 18 countries (N = 19,606). Using multilevel modeling, we found that climate change conspiracy beliefs were negatively associated with trust in scientists, policy support, emotional responses, and weather attribution. We also explored country-level heterogeneity, revealing cross-national variability in the strength of these associations and baseline attitudes.
