  • Searches the lower bounds of statistically significant external sea level trends in longest tidal records worldwide
  • Provides statistical evidences that the observed sea level change (SLC), at global and regional scales, is beyond its natural internal variability
  • Finds that the minimum anthropogenic sea level trend (MASLT) contributes to the observed sea level rise more than 50% in New York, Baltimore, San Diego, Marseille, and Mumbai
  • Finds a MASLT is about 1 mm/yr in global sea level reconstructions that is more than half of the total observed sea level trend during the XXth century
