Purpose: This study explored the efficacy of current U.S. government recommendations for individuals and households to prepare for natural and climate-related disaster. Methods: Utilizing a quantitative exploratory cross-sectional study, the researcher gathered electronic survey responses of adults living in the United States. Geographic and demographic data were analyzed alongside participant selection of natural and climate-related disaster likelihood in their location. Participants reported their gathered supplies, as well as potential barriers limiting preparedness ability, to identify any areas of statistical significance. Results: The results indicate that an average 38.7% of the recommended preparatory supplies set forth by the U.S. government have been gathered by participants nationally. Among disaster types, public perception of the danger of Extreme Heat Events (EHEs) is low compared to the threat perception of other climate-related and natural disasters. The analyses also found a statistically significant predictive link between political affiliation and concern for climate change. Within the California data subset, Hispanic and Latinx-identifying participants were found to be statistically less likely to have adequate household storage space for recommended preparatory supplies than their white counterparts. Discussions and Implications: The results seem to suggest that the U.S. government guidelines for climate-related and natural disaster preparation require more knowledge, time, and/or effort than most American adults are able to access. Among disaster events, extreme heat is a leading cause of mortality and vulnerable people (children, the elderly, the unhoused, etc.) are particularly harmed by a lack of public awareness and sustainable, protective infrastructure. The weaponization of the language of climate crisis is reflected in stark political divides among participants. However, when volatile language is removed, concern for the future is present across political ideologies, highlighting potential pathways for national consensus and action. To conclude, we discuss the implications of a federal climate disaster preparedness strategy that disproportionately burdens BIPOC and socioeconomically disadvantaged communities while simultaneously failing to address the existing environmental hazards to which these communities are exposed.
