Hurricane Seasons, Erosion, Rising Seas, Sinking Land Mass

Well, baws...if we can hurry up and convert those offshore oil production platforms to windmills, we might be able to save ourselves from these hurricanes.

Let's get on it!

It's amazing how posters with below 500 posts come on here only just to antagonize and aggravate. If only they would post on their real moniker. Trolls like that idiot have nothing better to amuze themselves.

Ehh...doesn't bother me much. At least there's some discussion with graphs and not just Facebook memes. Problem is if we get too far down the road on this, we'll have to kiss the whole thread bye bye.

It's amazing how a poster with below 13000 posts thinks that having a rational discussion about a relevant topic is antagonizing and aggravating. THAT is what is 'amuzing'.

Aalmost 13,000 posts and still absolutely no content

... Turbine-Draining aquifers certainly leads to subsidence but that is not the cause of LAs coastal issues. There is no aquifer underlying most of coastal SE LA where the vast majority of wetlands have been lost. Levees not allowing deposition of river silt, channelization of streams and O & G canals allowing saltwater intrusion have slowed deposition so much that it cannot keep up with natural erosion and subsidence...

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.

now that’s some content right there

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
