Unlike climate change, this is a self correcting problem. We'll tap the last of the fresh water, and then no more sea level rise (from that source). Problem solved, once and for all.

Solutions that include mass die-off of human populations are generally considered incomplete

But they are effective in reducing emissions.

I love the first world perspective. It pretends to be erudite while being completely inhuman. As if "emissions" are something you could ever get rid of. Any excuse to avoid making their own lives more efficient or the distribution of resources more fair.

This is an often repeated point, and many proponent of population reduction embrace it.

I think that's completely ignoring our consumption patterns. We're totally up to the challenge of burning twice the resources with only half the population.

I’m not sure this title is completely correct “The researchers identified the type of water loss on land, and for the first time, found that 68% came from groundwater alone — contributing more to sea level rise than glaciers and ice caps on land.” They are saying the leading loss of water loss is from ground water. The largest contributor to sea level rise I would guess is still thermosteric sea level rise due to the…

Quote from the paper: "the continents are now the leading contributor (44%) to mass-driven GMSL rise". As regards to non-mass-driven rise, another article[0] states, "Ice-mass loss—predominantly from glaciers—has caused twice as much sea-level rise since 1900 as has thermal expansion". I think the findings about sea level rise are as interesting as the ones about fresh water disappearance.

What is a "fair" distribution of resources in your perspective, in general.

Edit: Um okay, downvotes are quite telling.

It’s a good reminder that “climate change” will be a minor inconvenience for the rich, and an existential crisis for everyone else.

And that most of the inconvience will be needing to deploy robots to keep the poor away.

I think the change in lifestyle from using up all the groundwater would be pretty severe.

personally i'm just going to evolve

I have a tub in the kitchen sink to capture all dishwater, and make 4-5 trips outside to dump the water daily, into watering tubes that are six inches deep, around the dripline of each tree. Here in the SW US it is almost pointless to water at the surface, 90% or so is lost to evaporation within a day.

Just like the coal, gas, oil and forests - so exactly like climate change, in fact...

(It's a problem that saturates but not a problem that self-corrects, and the saturation point is undesirable in any case)

So they claim the majority of the water is ground water and also that it is due to climate change. But I thought I've seen other studies talking about how ground water is being depleted at a higher rate than it could be replaced, even using historical averages. This sounds more like a population/industrialization issue than a climate issue.

I think the distinction is between rainwater runoff vs aquifer depletion. They are related, and if we were collectively smarter we would do a better job of managing the runoff to help restore the aquifers.

in some parts of the country (US), interstate water agreements promise a certain volume of water to be delivered from one state to another, in which cases, runoff is sometimes required. Legal agreements.
