Climate experts project an average global sea level rise of 25 to 85 centimeters by 2100. Regional increases may even be higher. Their ramifications and necessary adaptations are considered the most cost-intensive aspects of climate change. Impacts vary greatly, however, depending on which coastal section is affected.
Therefore, the DFG-funded “SeaLevel” will investigate said repercussions based on two exemplary regions: Germany and southeastern Asia—the latter characterized by numerous megacities and river deltas. As the selected areas differ enormously in technical, social, economic, political, and cultural respect, data mining and analysis will provide us with very diverse information. This will allow us to simulate a broad spectrum of potential world-wide scenarios.
“Crafting “SeaLevel” into an interdisciplinary project was a conscious choice,” explains Professor Detlef Stammer, deputy chair of the strongly interdisciplinary Cluster of Excellence CliSAP. “Only in this form can we capture the complex interaction between societies and sea level rises.” In the end, we hope to create a toolbox of sorts that is to help the responsible local authorities find the best possible solutions for climate-induced problems.
Hence, “Sea Level” researchers have set out to pioneer the development of regional prognoses about sea level rise. They use basic oceanographic data of both regions to establish computer-generated climate simulations. Until now, results of simulations thus produced had a maximum resolution of five-hundred kilometers. Based on the so-called downscaling, “SeaLevel”, by contrast, will deliver prognoses with a rough accuracy of one kilometer, thus enabling us to make very exact predictions about specific coastal sections.
At the same time, the program will investigate and compare economic performance and resources as well as administrative organization and planning approaches in both regions. This requires that oceanographers, geographers, geophysicists and geodesists, glaciologists, and climate scientists cooperate closely with sociologists and economists. Germany’s earth system and climate research institutions offer ideal conditions for this major project“, says Detlef Stammer. “More than twenty researchers from all over Germany have jointly developed the newly approved program.”
