The hypothesis that experiencing extreme weather events can affect environmental concerns have long been discussed, yet rarely investigated. In a unique before and after design, 122 residents in Florida USA answered survey questions before and after experiencing hurricane Irma in September, 2017. After experiencing Irma, Floridians reported higher levels of negative emotions when thinking about climate change, a strengthened belief that Irma was caused by global warming, and they expressed greater willingness to sacrifice (e.g., pay higher taxes for the sake (...) of the environment). In addition, a mediation analysis found that for extreme weather experiences to result in pro-environmental actions, people need to feel that this experience was negative and think that they ought to do something about climate change.

This study explores the relationship between people's values, loci of control and pro-environmental behaviours. 'Locus of control' refers to the extent to which people attribute control over events in life either to themselves or to external sources beyond their influence: in the former case, the individual is described as having an internal locus of control, and in the latter, an external one. The study hypothesised, and subsequently concluded, that self-transcendent values and internal loci of control were positively related to pro-environmental (...) behaviours, and also that loci of control moderate the link between people's values and behaviour; people with a low degree of self-transcendence values behave pro-environmentally if they have an internal locus of control.
