Barriers to change: Climate change scepticism and uncertainty in Canada

In light of increasing green house gas emissions and severity of climate change impacts, elucidating the psychological barriers that limit climate change mitigation behaviour, especially in individuals from industrialised countries with poor mitigation performance, is important. This study sought to establish the extent of climate change scepticism and uncertainty in a representative sample of Anglophone Canadians, and determine the association with values,knowledge and socio-demographic factors. 229 participants responded to a mail invitation to take part in the online survey. Scepticism and uncertainty toward climate change were assessed using an attitudinal index that yielded a composite scepticism score. Environmental values were assessed using a modified version of the New Environmental Paradigm scale (NEP), and political association, climate change knowledge and several demographic variables were determined using established metrics. A full factor multiple regression analysis showed region, NEP score and Conservative Party of Canada association as the significant predictors of scepticism. Further regression modelling showed that values and politics explained 31% of the variation in scepticism scores, socio-demographic variables 6%, and education and knowledge3%. These findings highlight the dominant role of environmental values and political orientation, and are discussed in the context of the theory of socially-organised denial of climate change and the information-deficit model of climate inaction.
