    From InSAR‐Derived Subsidence to Relative Sea‐Level Rise—A Call for Rigor by P. S. J. Minderhoud, M. Shirzaei, P. Teatini

    Published 2025-01-01
    “…Thiéblemont et al. (2024, https://doi.org/10.1029/2024ef004523) reached a remarkable milestone by providing a continental‐scale estimate of vertical land motion (VLM) across European coastal zones by utilizing European Ground Motion Service (EGMS) data, obtained from Interferometric Synthetic Aperture Radar (InSAR) data from Sentinel‐1 satellites. Their findings reveal widespread coastal subsidence, with nearly half of the coastal floodplains, including major cities and ports, subsiding at rates exceeding 1 mm/yr, thereby exacerbating relative SLR. …”
