The European Climate Viewer, based on data from Copernicus Climate Change Service (C3S), is an interactive online tool providing harmonised climate hazard information across Europe. It was launched in October 2026 as part of the EU Framework for Climate Resilience, along with the Navigator for Climate Resilience Tools and the Mission Solutions Explorer. The Viewer operationalises the common reference warming trajectory, which is one of the core elements of the European Climate Resilience Framework. In this way, users can explore climate hazards across different locations in Europe for climate-sensitive sectors through an interactive map interface, in-line with the trajectory.
