    "... KEY INSIGHTS:
    • Coastlines are highly dynamic — 57% accretion vs 42% erosion
    • Strong contrasts between east-facing (Irish Sea) and south-facing (Atlantic) coasts
    • Identification of critical erosion hotspots (e.g., Tramore) and accretion zones in embayments
    • Coastal change is driven by a combination of wave climate, sediment availability, geology, and human activity

  3. #ESA:
    "
    River deltas are sinking faster than the sea is rising
    "
    ".. river deltas, home to about 5% of the global population .. are experiencing subsidence, which exacerbates the risks from sea-level rise. .. Sentinel-1 mission has captured a decade's worth of data showing land sinking faster than previously thought."
