Re: Shrinking freshwater availability increasing land contribution to sea level rise
#2Unlike 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.
Re: Shrinking freshwater availability increasing land contribution to sea level rise
#3So 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.

#4I’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

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”

The 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.

#6Interesting second order effect of global warming.

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

My reading of Figure 6 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-measu...

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.

personally i'm just going to evolve
