re: Good News! Sections of New Orleans' flood walls sinking at rate of nearly 2 inches a year

Just add 2 feet to each wall and do it again in 12 years.

They are not sinking, The water is rising. I saw this on an episode of Gilligan's Island.

So, what is the rate of sea level rise? 3 inches/ year?
Sinking faster than sea levels rising infers the opposite. The sea level rise is less than 2 inches.
As ice melts away from glaciers...new ice is continually being added via snowfall. The u.s built a huge nuclear powered base in the arctic and abandon it in 1967. Recent expeditions have shown its now under 130 feet of ice.
Propaganda convinces people that all the melting ice adds to the ocean levels. Most people are too stupid to realize the melt gets added back via snow. It's sad how most people are incapable of thinking for themselves

There is really no reason to live in Nola anymore.

I've taught this for years. Subsidence. People do not think about the fact that cities have weight. The buildings, roads, cars, people, dogs, food, etc. all push down on very spongy earth. The entire city is sinking; Some areas as much as an inch per year.

Not surprising after looking at pictures of the wall foundations during construction, It was done quick and cheap.

This is so stupid. If the walls were sinking slower than sea levels are allegedly rising the city wouldn’t flood?
And is the implied claim that sea levels are rising almost two inches per year? If so I would think Atlanta would have some pretty nice beaches by now.

NASA uses satellite radar altimetry, measuring the altitude of a surface from orbit with reflected radar pulses. They've been doing this since 1993.

I can show you 2 inches, but I would get banned for showing it.

Levee off the French Quarter and let the rest sink a slow death. It’s what’s best.

When your entire city is built on accumulated silt with no bedrock…
I read articles 10 years before Katrina predicting that eventually, New Orleans would just sink into the gulf. Even then they were measuring constant rates of sinking.

2 inches per year is not going to continue at a constant rate if its localized subsidence on immature sediments. New Orleans is sinking for sure but this kind of alarmism is why people dont listen. Quit fear mongering and do something useful to actually help rather than scream "we all gonna drown if yall dont start driving Teslas!"

Wait, so they are saying that sea levels in New Orleans are rising faster than two inches per year?
So, according to this report, the wall is actually losing a foot of protection every three years.
In short, in 30 years, the flood wall will be 10 feet “shorter” in terms of protection.
I’m calling bullshite.
I believe that these fricks are lying.
In three years, if that wall is a foot shorter, then this article will have merit.
Otherwise, piss off.

No, they are saying the opposite.

The study found that the city's concrete flood walls are sinking faster than sea levels are rising
They said the flood walls are sinking 2 inches per year so that would mean sea levels are rising less than 2 inches per year
quote:
Sections experiencing the highest rates of subsidence include floodwalls near the international airport, earthen levees in New Orleans East, and barriers in St. Bernard Parish. Some areas of the system are dropping at rates up to 28 millimeters per year. That’s more than seven times faster than the current sea level rise rate of about 3.6 millimeters annually.

What does this even mean?
From a geologic standpoint it means the land is subsiding. The Mississippi has been passing sediment into the GOA for millions of years. New Orleans sits on thousands of feet of that stuff. It would not pile up to those thicknesses under foot unless the surface subsides.

They focus on the equator.
Centrifugal force pools any excess water there. Even so, that equates to roughly 1.5 inches per decade at the equator.
When factoring in ocean currents near large land masses, it’s only in the open ocean that you see this growth rate.
Elsewhere, it’s not noticeable.
NASA is using cherry picked data to promote a narrative.
The primary factor for coastal flooding is now, and always has been, subsidence.
