While there is a growing body of literature on the effects of climate events on public opinion, this paper seeks to deepen our understanding of the increase of concerns about climate change following natural disasters. More specifically, it examines how localized natural disasters influence climate change awareness by focusing on the extremely high rainfall events of October 2024 in Eastern Spain. These torrential rains, which primarily affected towns south of the capital city of Valencia, caused widespread destruction of businesses, homes, and public property and resulted in over 200 fatalities. The disaster not only underscored the vulnerability of certain regions to climate change but also led to national debates on public policies design and State´s effectiveness to respond to those natural disasters. Using a Difference-in-Differences design, this research investigates shifts in climate change awareness in Valencia compared to the rest of Spain before and after this natural disaster. By integrating data from several public opinion surveys, the study aims to uncover whether populations directly affected by severe climate events exhibit a heightened awareness of climate issues relative to unaffected regions. The findings provide valuable insights into how localized climate impacts shape public opinion and highlight disparities in climate change perceptions across different individuals, helping policy makers, activists and other organizations to better understand these changes in public opinion following a climate catastrophe and allowing them, as a result, to act more precisely on communicational strategies to mitigate climate change impact.
