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

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.
Seem to remember reading some article a while back that said Houston was sinking.

m not sure what someone's reasonable expectations for flooding should be when you build a city below sea level.
I don't know why this gets repeated. It was built at or above sea level. The draining of the groundwater made portions of the city sink below sea level as organic content in the soil broke down due to a formerly anaerobic environment becoming aerobic.

If the actual sea level had risen over 4 inches in the past 30 years we would see significant global effects but we are not. 4 inches of water covers a hell of a lot of land.
That data is cherry picked and taken completely out of context to fit a narrative that doesn't exist in any significant measurable amount. It's very easy to skew data into whatever narrative you want. I could take points of the same raw data and show the exact opposite of what the chart shows.
Check out camp century in Greenland. Abandon by the U.S in 1967 and now has 130 feet of new ice on top of it. That's just one glaring example of real data that goes against the narrative. Glaciers are always melting at their edges...but the ice is rapidly replaced.

How much time have you spent in coastal environments over the last 30 years? They didn't have to leave the floodgates in Golden Meadow closed to keep water off of LA1 20 years ago. It's closed more than it's open now.

The floodgate you mention is opened every 30 minutes, it functions as a lock. It isn't closed to prevent normal sea levels from flooding.
The only time it's closed without scheduled openings at the top and bottom of the hour is when there is anticipated storm surge.

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
If what Corinthians posted is to be believed the sea level is rising and average of 1/8 of an inch per year.

As if we needed another reason to abandon that shithole. Yet the fedgov will spend more billions to try and save a dump.
I don’t understand why insurance and government paid to rebuild total losses in an area that is below sea level and will get totaled again. It makes no sense.

All of Louisiana suffers from subsidence far more than it does rising sea levels.
Even this study is a rehash of info given 5-8 years ago.

Not true at all. The coastal monitoring system throughout the gulf has been showing that sea level is rising here.
Not to a degree to where it is noticeable.
Subsidence yes, sea levels rising - no.
Unless, of course, you can see 3 millimeters of change.

3mm would be normal fluctuation...very minimal.
Nasa claiming 4+ inches of rise in a few decades is hilarious but people eat it up and repeat it without giving it any thought. Supposedly they started keeping tabs via satellite in 1993...because a satellite is gonna give you fine tuned and reliable measurements. It's measuring the ocean level in the most convoluted and least accurate method possible.
Had there been 4 inches of rise we would have seen drastic alterations to the coast lines world wide. A hell of a lot of land is 4 inches or less above sea level.

Yeah, my point is that if he were on the coast, there is no way he notices that change.

I'll start believing in sea level rise when Lady Liberty's toes start getting wet.

How to admit subsidence is the problem, not rising sea levels, without admitting that subsidence is the problem, not rising sea levels.

What the article fails to mention is USACE accounted for relative sea level rise in the floodwall design so it’s not a big deal.
