DASNordicSLR - Sea Level Projections for Northern Europe

Corinna Jensen , Frank Janssen, Tim Kruschke

Sea level rise is an inevitable consequence and one of the most significant threats posed by climate change, increasing the risk of flooding in low-lying areas along the German coast. Based on the IPCC 6th Assessment Report (AR6) projections we aim to deliver improved projections of relative sea level change for Northern Europe’s coastal regions. These projections are available as spatial data up to 2150. While most drivers of sea level change operate on a continental or global scale, vertical land motion is a regional factor – particularly relevant in northern Europe - resulting from glacial isostatic adjustment and local processes. By combining the IPCC projections of absolute sea level change with a new, high-resolution land elevation model for Fennoscandia, an optimized set of projections for relative sea-level change for the North Sea and Baltic Sea was developed. This dataset represents a contribution to the DAS core service “climate and water”, the operational climate service operated by four federal authorities under the umbrella of the German Federal Ministry of Transport.
