accelerates local sea level rise from climate change, because the land is getting lower as the ocean gets higher.
Gotta tie it into global warming somehow.
This particular issue has nothing to do with it, and is at a faster rate. River deltas meander back and forth (like rivers themselves). As such, they are constantly depositing fresh silt, back and forth, back and forth.
Build a city, put in levees to guide the river, and this process stops. The weight of the city and the silt it is built on slowly squeeses out water, squeezes it down. New Orleans is 6 feet below sea level, as we found out 20 years ago.
The process is slow, allowing easy building of sea walls, but much faster than sea rise.
