Shrinking freshwater availability increasing land contribution to sea level rise
- jfengel 1y agoUnlike 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.
- treyd 1y agoThe polar ice caps are the same way. Once we melt all the ice then the sea level rise will stop, and we can just deal with the change in lifestyle.
- oh_my_goodness 1y agoI think the change in lifestyle from using up all the groundwater would be pretty severe.

- DaveZale 1y agoI 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.
- fooker 1y agoYou can also hibernate in pokeballs when things get bad. Foolproof plan.
- Gibbon1 1y agoConsidering current shitshow reaction to having to deal with smaller issues I'm not optimistic about how that's going to play out.
- marcosdumay 1y agoWell, that applies to most of our habitat-change problems.
- causal 1y agoSolutions that include mass die-off of human populations are generally considered incomplete
- Ekaros 1y agoBut they are effective in reducing emissions.
- firstworldfail 1y agoI 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.
- makeitdouble 1y agoThis 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.
- ada1981 1y agoIt’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.
- slt2021 1y agothats what revolutionary movements are for: to organize "everyone else" and physically purge the elites that dont care about the crisis affecting regular people
- cutemonster 1y agoNowadays the revolutionary movements listen to Twitter and go hunting immigrants instead, the elite has never been safer?

- andyferris 1y agoJust 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)
- giantg2 1y agoSo 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.
- pstuart 1y agoI 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.
- DaveZale 1y agoin 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.
- pstuart 1y agoYes, it's not about capturing every drop -- more about slowing it down so a fair amount can percolate in. The recent tragedy in Texas is a key example -- way more water than could be "handled", and if there were mitigations in place it could have been win/win (temper flooding and replenish aquifers. I follow a youtuber who's trying to rehabilitate desert land by slowing the water down to let some percolate in -- it's a wonderful dream: https://www.youtube.com/@dustupstexas https://www.youtube.com/@dustupstexas

This sounds more like a population/industrialization issue than a climate issue. I'm not sure I understand where you see a contradiction. Land areas are using groundwater faster than it can be replenished, so land is getting drier. That's according to the article (just basing of the summary not the scientific one) is driven by both overuse and drier and warmer weather. The thing is, that's a feedback loop, if it gets drier we'll be using more groundwater for irrigation. So both processes are driven by climate change.
- garrettdreyfus 1y agoI’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 ocean becoming warmer and less dense See ipcc https://www.ipcc.ch/report/ar6/wg1/chapter/chapter-9/ https://www.ipcc.ch/report/ar6/wg1/chapter/chapter-9/ 9.6.1 Global and Regional Sea Level Change in the Instrumental Era In particular, Cross-Chapter 9.1, Figure 1 | Global Energy Inventory and Sea Level Budget. Panel b EDIT: @dang could the submission title be changed to the article or journal article title? “New global study shows freshwater is disappearing at alarming rates” Or “Unprecedented continental drying, shrinking freshwater availability, and increasing land contributions to sea level rise”
- garrettdreyfus 1y agoMy reading of Figure 6 https://www.science.org/doi/10.1126/sciadv.adx0298 https://www.science.org/doi/10.1126/sciadv.adx0298 suggests that this study still has thermosteric effects making up the majority of sea level rise. I also highly recommend reading up on the GRACE satellite used in this study it is amazing https://gracefo.jpl.nasa.gov/resources/50/how-grace-fo-measures-gravity/ https://gracefo.jpl.nasa.gov/resources/50/how-grace-fo-measu...
- yboris 1y agoThank you for sharing, GRACE-FO feels to me like a brilliant design!
- mturmon 1y ago> it is amazing Indeed! The GRACE measurement of mass change is one of the more revolutionary advances in Earth science remote sensing in the last few decades. It has provided a unique and completely novel view of groundwater mass change. Grace is the main reason we know so much about the massive groundwater loss in the Oglala aquifer in the US Midwest, in the Central Basin in California, and in northern India. Water well data exists but it is very sparse and idiosyncratic. It’s also our main window into mass losses in ice sheets in high latitudes (Greenland, Antarctica). We have radar altimetry data from Antarctica, but because of glacial rebound and other effects, it’s not easy to translate height changes into mass changes. Grace measures mass change directly. Several authors of the cited study are on the science team. It is a JPL instrument. The original Grace pair used radio to measure separation and velocity, while the follow-up Grace-FO uses a laser. I assume the small wavelength of the laser provides a more accurate measurement. It’s possible that Grace-FO has a slightly higher spatial resolution (I’ve worked with Grace but not Grace-FO); the horizontal resolution of Grace is about 100km or about 1 degree. From an inference perspective the measurement is very interesting. They pool about a month’s worth of observations of the distance and velocity of a pair of satellites, and do a Bayesian inversion to obtain a parameterized gravitational potential for that month. The map from gravitational potential to observation is known analytically, so it’s readily possible to get a spatial covariance for the gravitational potential, as well as the point estimate.

- HocusLocus 1y agoSea level rise (#2) is a 'crisis' for absolutely no one. I set an alarm for (#1), "Preparing for the low pressure 12ft tidal/storm surge or the 18ft tsunami that could arrive as early as tomorrow and probably will within 10 years, unless one is incredibly dumb or has never lived near the ocean." I did not set an alarm for #2.
- misja111 1y ago> “Continents are drying, freshwater availability is shrinking, and sea-level rise is accelerating. Does anybody have any data about the accelerating sea-level rising? As a Dutch person I'm of course very interested in this, but I can't find any data that supports this.
- BlackFly 1y agoThis is what I found: https://ourworldindata.org/grapher/sea-level https://ourworldindata.org/grapher/sea-level I don't see much of an acceleration...
