Hazard maps use estimated sea level rise due to climate change to determine flooding risk for today’s shoreline, but don’t take into account that some land is sinking.

A precise study of subsidence around San Francisco Bay shows that for conservative estimates of sea level rise, twice the area is in danger of flooding by 2100 than previously thought. Some landfill is sinking 10 mm per year, threatening the airport and parts of Silicon Valley…

Sinking Atlantic Coastline Meets Rapidly Rising Seas; Climate Central (04-15-2016)
Geological changes along the East Coast are causing land to sink along the seaboard. That’s exacerbating the flood-inducing effects of sea level rise, which has been occurring faster in the western Atlantic Ocean than elsewhere in recent years…

New Study Finds Sea Level Rise Accelerating; NASA (02-13-2018)
Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satellite data…
