Extreme atmospheric and hydro-meteorological events such as storms and storm surges, hail, floods and heat waves seem to be to increase more and more. It seems that the weather is going crazy more and more often. This is why scientists, the media, politicians, administrations, insurance companies and the general public are increasingly asking the question: What role does climate change play in the context of extreme weather events (EWEs) and to what extent does this contribute to their frequency and increase and decrease in intensity?
Thus, the topic is highly topical and actual research is focusing on the question how and to what extent climate change currently influences the different EWEs - depending on their region - and which changes can be expected in the future. First research results have already shown that changes in the frequency or intensity of certain EWEs - such as heat waves or winter storms - can be attributed to climate change. In addition to a change in the vulnerability of goods, a change in the exposure of values and the impact on humans as a whole, global warming will also have an additional impact on global and national damage and loss rates caused by weather extremes, as well as on regional and local levels. In this respect, a public understanding of the phenomenon of climate change is emphatically demanded by science, politics and administration in order to sensitize people to this problem and to increase their readiness for mitigation and adaptation measures, especially with regard to weather extremes.
It is precisely the point at which the present research project "Regional risk cultures of extreme weather events" will address. Starting from a lifeworld perspective and beyond scientific or media assessments, it focuses on the concrete social and cultural experience as well as on the perception and evaluation of EWEs. Thus, regionally typical EWEs such as storm and storm surge on the North Sea coast in Schleswig-Holstein, hail events and heat waves in Baden-Württemberg or flood events in Central Germany will be analyzed from a socio-cultural perspective in order to investigate human-extreme weather interactions and regional risk cultures. As a first step, the first aim of the project is to gain a better understanding of the social and cultural dimensions and their connection with EWEs region-specific conditions. Subsequently, the regional experience with and knowledge of weather extremes, individual and collective risk perception, interpretation and risk action will be placed in a regionally specific context..
In the context of the project, the following scientific questions will be addressed, in particular in dependency on the different regions will be studied:
- What are the paradigmatic experiences with EWEs?
- How are these EWEs perceived, explained and evaluated from the public?
- Are there historical experiences with EWEs and do they play a role for perception, explanation and evaluation?
- Do perception and interpretation change after EWE and if so, how?
- What role does climate change play in the interpretation of EWE?
- What are the regional con- and divergences with regard to perception and interpretation of EWEs and how can they be explained?
- How do risk perceptions, assessments and actions differ in terms of experience with and knowledge of EWEs?
- What safeguards have been, are being or could be taken and why?
- How are risk interpretation and risk action related to the individual life context or to the spatially different distribution of EWEs?
- Can regionally specific risk cultures be reconstructed and how are they organized?
The project "Regional risk cultures of extreme weather events" is split into two phases: In the first phase, street surveys on EWEs will be carried out at selected locations in Baden-Württemberg, on the North German North Sea coast and in Central Germany. In a second phase, the results of these quantitative surveys will be analytically and empirically deepened through qualitative interviews with citizens from the survey locations of the street survey. Finally, the analyzed data sets are combined and - if possible - regionally specific risk cultures are aggregated.
The interdisciplinary research project is carried out in the context of the Helmholtz Initiative REKLIM and is performed by the Topics 6 and 7. The institutional cooperation is realized in cooperation with the University of Hamburg, the Helmholtz Centre Gesthaacht (HZG) and the Helmholtz Centre for Environmental Research (UFZ).
