Updated land-elevation models reveal many coastal regions are lower than we thought, according to a new study in Earth’s Future. The first 1 to 2 meters of sea level rise will therefore inundate about twice as much land as earlier elevation models suggested.
According to current models, the most significant effects of sea level rise are expected to take place once it reaches several meters. However, a recent study has uncovered that the largest increases in flooding will occur after the first 2 meters of sea level rise, affecting an area of land that is more than double what was previously predicted by older elevation models.’s ICESat-2 lidar satellite, launched in 2018, to enhance models of sea level rise and flooding.
The underestimates of land elevation mean coastal communities have less time to prepare for sea level rise than expected, with the biggest impacts of rising seas occurring earlier than previously thought. After those first few meters of sea level rise, the rate at which land area falls below mean sea level decreases.
Using the new measurements of land elevation, Vernimmen and co-author Aljosja Hooijer found coastal areas lie much lower than older radar data had suggested. Analyses of the new lidar-based elevation model revealed 2 meters of sea-level rise would cover up to 2.4 times the land area as observed by radar-based elevation models.
