Midwestern droughts have reduced the flow of the Mississippi. Groundwater depletion has caused coastal land to sink below sea level. Sea-temperature increases raised the sea level in the Gulf. The result: rising ocean waters are out-competing the Mississippi flow, pushing up the riverbed, and will reach New Orleans’ water treatment plant. The city’s water supply will be undrinkable, while the salt leaches poisons out of lead pipes. They have one month.

Map: When Will the Saltwater Wedge Reach New Orleans?

The drought-stricken Mississippi River can no longer hold back the saltwater creeping upstream, contaminating drinking water.

The New York Times
Good news: the US Army Corps of Engineers says that increased rainfall in the Red River basin has increased the Mississippi's flow, which has caused the salt water wedge to move back downstream some. They've also raised the level of an underwater sill holding back the lower layer of salt water. It's forecast to keep advancing, but more slowly, giving time for rainfall in the Mississippi basin to keep it from reaching New Orleans and leaving them without drinking water. https://www.mvn.usace.army.mil/Media/News-Releases/Article/3554703/latest-saltwater-wedge-forecast-released-by-usace/

@waldoj I didn’t like the part where experts were warning this stuff was coming and wealthy and powerful people did everything possible to make sure it happened anyway and I don’t like this part either
@waldoj I keep thinking about when we will just flat be out of engineering options for New Orleans' long-term ability to be a major city. This feels like a domino falling
@taber @waldoj
This was obvious after Katrina.

@waldoj

Now imagine having to replace the water delivery system of every major coastal city around the globe over the next 10 years.

@waldoj No. Nooohooho. You can't be serious. Does this mean that the drinking water supply for… how many people? Half a million? One? Is at stake? Right? Now?
Edit: WTF? No offense. I'm not doubting the facts.
I'm just like… Holy F. Shit, this is a dystopian nightmare even Hollywood would deny as too messed up.

@musevg @waldoj "surprise! You have 30 days to Save The City!" (opening in theatres soon)

We answer your questions about the saltwater wedge in the Mississippi River

As salt water moves up the Mississippi River from the Gulf of Mexico, residents across the greater New Orleans area have been left with many questions.

@waldoj I did not read the article yet. Does it include the impact on water tables from the 1.5 trillion gallons used for fracking? How the ChatGPT cooling impact?

@waldoj so much of this water shortage is exponentially compounded by cooling data centers for AI and blockchain.

Not only do they burn insane amounts of fuel. They destroy aquifers.

They want to blame it on our internet use, but it is their theft of our data and surveillance capitalism, and corporate ponzi schemes and all it's waste that is causing it.

It's for stuff no one wanted but the oligarchs wanting total domination over the whole world, damn the cost.

In the American West, data centers are clashing with local communities who want to preserve water amid drought

@waldoj
Sadly it won't work.. we did this.

@GatekeepKen @waldoj “Government officials at all levels have expressed the same message: There’s no need to panic.” - this happens every so often and once this far in 1988. Alarmist reporting like this sucks for the cause when it’s so easily refutable.

@StevenBarnhart @waldoj

That's silly thinking we're not in different times. If you think man can overpower Mother Nature. I have a city to sell you that used to have a great Mardi Gras.

@waldoj yet folk still say it’s a lie and all part of a global conspiracy.

@waldoj Ah, the unexpected joys of continually dredging the lower Mississippi so the oceangoing ships can make it up to the port of New Orleans. The riverbed has been dredged to about 30(?) feet below ocean level, so of course the ocean will creep in at the slightest provocation.

*sigh*

It's long past time for a St Bernard canal with actual locks, but that would cost money and why spend pennies now when you can watch dollars blow away in the wind tomorrow?

@waldoj it’s not great but also there is work being done to fix it. Why are you being alarmist and not mentioning this happened before in 1988? Or the plans to mitigate? https://www.wwltv.com/article/news/local/saltwater-intrusion/construction-of-10-to-12-mile-pipeline-could-curb-saltwater-intrusions-impact-on-new-orleans/289-2b4024d1-63e8-467c-81b4-55cea17670e0
@StevenBarnhart Why am I not personally doing a bunch more research beyond reading an article on the topic before writing a single comment on Mastodon? That’s a thing you are seriously asking me?

@StevenBarnhart @waldoj So it happened before once, that means it's normal so it's fine?

Really? That's your argument?

While sea level keeps rising and ground water keeps subsiding, it's going to get worse.

When exactly is it time to be alarmed, anyway?

@violetmadder @waldoj I’m against the lack of mentioning any of that. The article makes it seem like something we’ve never seen before and is written to induce panic. Then, people will learn and assume every article on climate change effects is fear mongering.
@StevenBarnhart @violetmadder Cool next time I’ll jam that context into the remaining 8 characters in my post
@StevenBarnhart @waldoj I don't see anything alarmist in the original post. It just passes on facts drawn from a news article. It's not the poster's job to reassure people if they find those facts alarming.
@anne_twain @waldoj well, a lot of “we did this” but I incorrectly assumed the poster had written the article.
@waldoj As [email protected] put it,
"AAAAAAAAAAAAHHHHHHHHHHHH." That's terrifying!
@waldoj Wasn't it within a year that people were talking about "solving" the problem of drought in the Western US by diverting water from the mighty Mississippi? And now even that river is depleted. And yet we continue to use our diminishing groundwater reserves to pump "car juice". What are we thinking?
