Natural hazards as teachable moments? : A natural experiment-based study examining the effect of natural hazard exposure on individuals’ climate change concerns and willingness to adopt climate change-related actions

Abstract: Natural hazards are an important way for individuals to experience consequences of climate change. It has therefore been suggested that natural hazards could act as opportunities to increase individuals’ concerns about, and willingness to act on, climate change. The empirical evidence within the field is however mixed. Moreover, the research field is drawn back by methodological shortcomings, as studies rarely have been able to make valid pre-hazard assessments. A more accurate estimation of a possible causal effect is enabled in this study, as a survey mapping climate change opinions was conducted in Germany when the country was hit by a rare and severe hazard event, namely the European Floods. This provides an opportunity to examine the effect of hazard exposure on individuals’ levels of climate change concerns and willingness to adopt climate change-related actions. Three sets of hypotheses are tested using two-sample t-tests. The findings suggest that natural hazards have limited potential to act as teachable moments; climate change concerns may increase, but not willingness to take action. Political ideology is found to slightly moderate the effect between hazard exposure and climate change concerns, but only among right-leaning individuals. These findings make an important contribution to a mixed research field.
