Despite segments of scepticism, the majority of the general public in most countries believe that climate change is occurring and caused by human activities. Behavioural changes by individuals can reduce greenhouse gas emissions to at least some extent, but a range of psychological and economic barriers can prevent individuals from taking action. A survey of New Zealanders by Aitken, Chapman and McClure (2011) reported that belief in human influence on climate change and the risks of climate change were positively correlated with the probability of taking action on climate change. Conversely, perceptions of powerlessness and the commons dilemma were negatively related to the probability of taking action. Feeling powerless was associated with placing less importance on climate change as an influence on actions. Although Aitken et al’s study has been influential, it was exploratory in nature, had a moderate sample size, was not preregistered, and has not previously been replicated. In this study we report a preregistered replication with a sample of 352 Australians. We were able to reproduce each of the key findings stated above.
