Effective adaptation to climate change requires detailed, tangible information about its impacts. This paper presents a novel simulation framework that combines storyline approaches based on spectral nudging with emerging kilometre-scale global climate modelling capabilities using the IFS-FESOM model. This approach allows for reconstructing recent extreme events and their potential evolution under different climate conditions while maintaining high-resolution local details. We demonstrate the system’s ability to reproduce observed variability on daily and longer timescales during the 2017–2023 period, particularly in the extratropics, and evaluate its performance using high-quality observations, including data from the MOSAiC expedition. To showcase the potential of this framework, we focus on two recent extreme events in Europe: the July 2019 heatwave and the July 2021 Ahrtal flooding. These examples highlight how kilometre-scale simulations can provide more granular, localized insights into climate change impacts, improving risk assessment and adaptation planning. This work, conducted as part of the European Union’s Destination Earth initiative, demonstrates how global, high-resolution simulations can be harnessed to support the development of digital twins of the Earth system, advancing both climate science and practical decision-making.
