Louisiana is an outlier situation. The state is built on mud jello, which is why a gravel road in Nebraska is more stable that an interstate running through Louisiana
It is also why when the dozen or so inland aquifers cause undetected subsidence the jello on the coast slides inward and follows suit.
It's hindsight and not their fault, but once the railroads decided to sell off the rice canals, the farmers should have found a way to coop ownership of the canal system. Of course, they were only shown how easy it was to extract billions of gallons of water from the aquifers and were even given grants and low interest loans to do just that.
You rightfully mention the lack of new sediment coming in but that is only part of the equation. That sediment that was once deposited was chock full of organic material. So ever since what you have is an ongoing composting effect, as the organic compost degrades it takes up much less space. Not being replaced. Some of the organic material takes decades to degrade and shrink.
The Dutch of the 16th Century and Cajuns of the 17th Century found a solution.
Today humans just want to do nothing and blame other humans, looking only at the false visual of what appears to "only" be rising oceans.
This is fixable, the solution is in the Cajuns history, they should lead the way.
Of course they did…
I have never heard of inland aquifer depletion as a cause of coastal subsidence. The fact is that because of the unconsolidated nature of the sediment, the weight of the overlying sediment compacts what is under, hence subsidence, especially with no replenishment from floods.
In this case, 'blaming humans' is 100% on target. The only feasible way to keep up with land loss, probably way too late to reverse it, is sediment redistribution from levee breaks like the Wax Lake Outlet project.
This is a cool project but like all the solutions, very expensive. https://www.fisheries.noaa.gov/featu...n-noaa-funding
We need a few powerful hurricanes to sweep through the North Atlantic near New England and other areas installing offshore windmills. The hurricanes might knock all that crap down and put an end to that foolishness and waste of taxpayer money in the form of government subsidies! If wind and solar was indeed the answer, the government would not need to subsidize those efforts. The U.S. has enough fossil fuel available to power our country for years to come. Just allow us to drill, drill, drill!
I find it interesting that they include temperature measurements over such a long period of history and don't mention that the device used to take the measurement has changed. Obviously, measuring devices 10, 20 or 50 years ago do not measure up the the precision of the current measuring devices or methods. How are temperature measurements made today versus in the past? Were they taken at the same time of day or month, at the same location? Who is paying to take the measurements? Have the storms in the southern hemisphere been more active this year? It seems like the southern hemisphere is just as sensitive to global temperature changes as we are in the northern hemisphere. Inquiring minds want to know.
Man-made Heat Islands are real.
Any data taken from these areas is garbage.
