Climate Change Impact Assessment, assesses climate change impacts on Lower Saxony to develop mitigation and adaptation scenarios. Using state-of-the-art regional climate simulations, Phase I examines past, present, and future climate effects on LS. Phase II involves new regional climate simulations tailored to Lower Saxony’s conditions for enhanced accuracy and applicability.
In Phase 1, we use existing knowledge from climate research for Lower Saxony to make statements about past and present changes. The knowledge is based on existing available model simulations of different spatial scales and the current state of scientific literature. For the study areas, these fundamentals will be re-examined and redeveloped in order to better respond to them.
The aim of phase 2 is to create new regional climate simulations with an adapted modelling approach from the investigations of phase 1 in order to improve the project-specific requirements and information for Lower Saxony. Possible models for this are, for example, the regional climate model REMO for hot-spot areas or weather events with a major impact.

Dr. Claas Teichmann is a scientist at the Climate Service Center Germany. He studied physics in Göttingen, Lyon and Bremen, then joined the regional climate modeling group at the Max Planck Institute for Meteorology. His doctorate examined how megacities affect air quality in South America. He contributes to projects like IMPACT2C (2 °C warming) and supports EURO-CORDEX for high-resolution regional modeling. He helped launch the journal Climate Services, bridging science and practice. His research focuses on climate extremes in low-emission scenarios and on developing modeling chains to quantify uncertainties from global signals to local impacts.

Riddhima Puri is a doctoral researcher at the Climate Service Center Germany. She holds a Master's in Earth and Environmental Sciences from the École Normale Supérieure Paris, specializing in atmosphere and ocean sciences. Her research interests broadly focus on climate variability, impacts, and communication. Her Master’s thesis focused on how land-use changes and aerosols affect long-term shifts in the Indian monsoon using global climate models. Her latest work as part of an EU project, SUNRISE, explores how climate impacts critical infrastructures. She aims to further integrate climate model data at the regional and local level under the UCFL project.
Based on modern climate model simulations taking into account results from previous projects, we will investigate different climate change conditions. Our research will be based on the latest results from EURO-CODEX with the RCPs at 12.5km resolution, including newly available convective simulations at about 3km resolution. These new simulations will be used in a well-established regional climate model (REMO-nh) to include urban areas. This will allow us to assess climate change locally within LS and answer the key research questions of whether some regions are more affected than others and whether there are correlations with settlement types or landscape types. The analysis takes into account particularly drastic events, specifically affected areas and also the possibility of compound events.
