The junior research group GRUSS (Geoinformatics for climate Resilient Urban SystemS) is funded by the Volkswagen foundation as a Freigeist Fellowship for six years, starting fall 2022. Our work combines (big) data science with geospatial data to study the impacts of  urbanization and climate change on society and nature. Particular interest is on the role of the built environment on atmospheric, surface, and subsurface temperature disparities.

Patricia Glocke and Svea Krikau Lecturers @ Summer Academy at Salem International College

The Summer Academy in Baden-Württemberg empowers talented students, especially those from disadvantaged backgrounds, to explore diverse disciplines beyond standard curricula. Patricia Glocke and Svea Krikau taught climate and environmental sciences, covering climate science fundamentals, Python and Google Earth Engine for data processing, and sensor technology. Students developed projects like nightlight evolution and forest fire monitoring. Evening expert talks fostered rich discussions. This hands-on program enhances academic and personal growth, preparing young talents for future challenges.

Dr. Susanne Benz Discusses Her Latest Publication on alleWetter - Watch the June 20, 2024 Episode Here

Dr. Susanne Benz from KIT explained the effects of climate change on groundwater temperatures during her alleWetter interview. She highlighted how rising air temperatures also heat groundwater, with regions like the Sahel Zone and northern Australia experiencing extreme temperatures up to 34°C. This warming impacts ecosystems, human health, and energy systems, making groundwater more prone to pathogens and chemical dissolution. Additionally, warmer groundwater affects fish habitats, like salmon spawning in rivers. Dr. Benz emphasized the long-lasting nature of this warming, requiring decades to reverse even with significant climate mitigation efforts.
