Abstract. The Climate Change Adaptation Digital Twin (Climate DT), developed as part of the European Commission’s Destination Earth (DestinE) initiative, is a pioneering effort to build an operational climate information system in support of adaptation. This system produces global climate simulations with local granularity, providing information at scales that matter for decision-making. The Climate DT delivers multi-decadal climate simulations at spatial resolutions of 5–10 km, with hourly outputs, offering globally consistent, frequently updated data. The km-scale simulations address some limitations of current climate models, improving local granularity and reducing longstanding biases, supporting more equitable (understood as accessible and relevant across regions) and credible climate information. The Climate DT is built on cutting-edge infrastructure, expert collaboration, and digital innovation. It supports real-time, on-demand responses to policy questions, with quantified uncertainty. It fosters interactivity by allowing users to influence simulation design, model outputs, and applications through co-design. AI-based tools, including emulators and chatbots, are being developed to enhance flexible scenario exploration and ease climate information access. Sector-specific applications are embedded in the system to generate tailored climate-impact indicators, with examples for energy, water, and forest management. The applications have been co-designed with informed user...
