California Aquifer May Have Crossed the Point of No Return
A California aquifer may have crossed the point of no return
Intense pumping during the 2020 drought caused the Sacramento Valley aquifer to compact permanently, losing its ability to rebound even after heavy rains. While some experts remain skeptical about the permanence of this subsidence, satellite data and preliminary observations suggest the groundwater storage capacity has been irreversibly damaged. This regional collapse highlights the urgent need for stricter groundwater management to prevent future water scarcity.
Water resources are going to become more and more scarce, and so being able to have access to this water resource in a sustainable manner for the century to come is important. Otherwise, we won't have it for very long.

Why can't we work up the political outrage over water-wasting agriculture in California that we managed to gin up over data centers: https://finance.biggo.com/news/202508220112_Data_Centers_vs_...
> Alfalfa irrigation (Colorado River): 1.6 trillion gallons annually
> Google data centers (global): 6.4 billion gallons in 2023
> Thermoelectric power plants: 41% of total US water use
EDIT: that page has a correction to some of the other numbers on the page, but the 6.4 billion gallons number quoted above for Google's data centers is in line with other sources: https://mostpolicyinitiative.org/science-note/data-center-wa... ("Google reported their data center water consumption increased from 4.3 billion gallons in 2021 to 6.1 billion gallons in 2024.").

California has codified a water caste system. In 2015 (my last experience with this), citizens were ordered to cut water use 25% while ~400 pre-1914 claimants with magical "senior water rights" took 90% of the water. [1][2]
We conserved, rates still rose, f*ck the poor the most, so that select farmers can use however much water they want. During a drought. As allowed and protected by law.

There are some reasonable books by William T Volleman called 'Carbon Ideologies' it is all about Nuclear and Coal power. Regardless of that, they are written focusing on the people that would be reading those books in a few hundred years time. The justification being that those that read it today already understand the issues. As such they are focused on a world that is deeply resource depleted and much hotter.
But it is the opening chapter that is very explicit in trying to highlight how most people live today. It isn't that we don't know what is happening or that we do not care, it is just that we have needs and wants that unfortunately have long term blow back. We are just trying to take care of others, but that is leading down a less desirable path.
I thought it was a great message that needs to sent to the future.
The aquifers are being drained, but it was being done to feed the people. Yes, it could have been handled much better but that core driving force behind it will probably be the same in hundred of years from now.
If that message isn't sent forwards, the stories that will be made in our place will not be very kind to us.
If that matters or not, that is up to you to decide. And that is the whole debate on 'What is legacy?'.

I see parallels between water rights "xxx acre feet per year" without regard for how much water is incoming, and pension funds where they simply declare how much will be paid out.
I really can't tell the difference between people being uncaring or just stupid about either.

>In an aquifer that’s permanently collapsed, artificial recharge—pumping water forcibly back underground—is the only option, according to Shirzaei. That’s expensive and carries the risk of triggering earthquakes.
I have spent most of my life in the San Joaquin Valley and what I have been wondering about over the past few years is what is the effect removing all that water from the faults. Specifically, does this water removal cause the stresses along the faults to build making the resulting earthquakes larger?

As the Super El-Nino is at its peak, South India is facing an acute water crisis

Interestingly none of our Govts. or Leaders are talking about conservation yet and the ancient water laws/standards don't take climate change into consideration. For eg. as per BIS IS 1172: 1993 standards an average Indian is entitled to 135 Liters of water per day when the actual supply is not even close to 50 liters per Indian per day. This is level of water crisis India is facing today.

Most of the southwest should not have people living in it. It's a fake place that is enabled to exist by massive and unnatural engineering projects, like dams on the Colorado river. We need to create a long term plan to relocate the population to other parts of the country.

Who cares there is so much more to exploit. For example no-one has yet moved massive freshwater icebergs by boat, and its up for grabs!
