So it will take another million yeas before it sinks?
Actually all of the Mississippi Delta is less than 10,000 years old. I am pretty certain there is some very interesting human artifacts and settlements that are buried under the 350 feet of sediment deposited since the end of the ice age. 10,000 years ago sea levels were 350 feet lower than today and we all know that most cities are near the coasts along rivers.
They do need a way to get sediment from the river to start rebuilding the delta but this is pure alarmism by nerds looking for government grants.
[[but this sinking may well be happening faster than previously thought—threatening billions and billions of Louisiana oil infrastructure.]]
At which point we’ll just have to convert the wells to undersea ones- no big deal- plenty of time to prepare
Look at decadal geographic maps of the coast for the last only half century. There is a hell of a lot more water in Southern LA now than there was in 1984, when I traveled about the area.
