Developing a cloud-based service offering actionable coastal climate risk and adaptation data across Europe

Coastal zones face increasing climate-driven hazards such as sea-level rise, storm surges, flooding and erosion, threatening infrastructure and ecosystems. Addressing the need for actionable climate information in adaptation planning, we developed an integrated Coastal Climate Core Services platform for Europe that consolidates sea-level projections, flood and erosion maps, exposure data, damage estimates, and adaptation options into a unified, cloud-based service. Co-designed with national authorities, municipal planners, and infrastructure owners, the platform offers an interactive web viewer for non-experts and a collaborative coding environment for advanced users. It delivers localized, FAIR(Findable, Accessible, Interoperable, Reusable)-compliant data supporting evidence-based adaptation planning and compliance with European frameworks. By bridging scientific data and operational climate services, this platform ( https://platform.coclicoservices.eu ) enhances climate resilience and informs strategic coastal risk management across Europe and shows how a broad-scale coastal climate service can be delivered.
