Variations in climate change belief systems across 110 geographic areas

Climate beliefs shape engagement with climate action, yet research often overlooks their interconnections. This research frames climate beliefs as a belief system and examines two structural features: density (the strength of all connections) and inconsistency (conflicts between beliefs). Using Facebook survey data from 110 geographic areas (n = 99,074), we show that global north presents higher density networks, where climate beliefs are more tightly correlated, while many global south areas have positive but less interconnected beliefs. Inconsistency appears in geographic areas where opposition to reducing fossil fuel use conflicts with support for renewable energy and government prioritization of climate policies, such as in the Middle East. Information exposure is positively correlated with density and negatively with inconsistency. Gross domestic product per capita is positively associated with density and carbon resource dependence positively correlates with inconsistency. These findings offer communication strategies to enhance climate belief endurance while addressing conflicting beliefs that may undermine climate action. Climate beliefs do not exist in isolation but form an interconnected network known as a belief system. This study analyses the density and inconsistency of belief systems and their associations with informational and socioeconomic factors to inform effective climate change communication strategies.
