Majority of groundwater stores resilient to climate change:

Fewer of the world's large aquifers are depleting than previously estimated, according to a new study by the University of Sussex and UCL.

[...] Previous global studies of changes in groundwater storage, estimated using data from the GRACE (Gravity Recovery and Climate Experiment) satellite mission and global models, have concluded that intensifying human water withdrawals in the majority of the world's large aquifer systems are causing a sustained reduction in groundwater storage, depleting groundwater resources.

Yet this new study, published in Earth System Dynamics, reveals that depletion is not as widespread as reported, and that replenishment of groundwater storage depends upon extreme rainfall that is increasing under global climate change.

Aquifer depletion is occurring only in 5 localities.

    Yeah, that's part of the 'contamination' issue. We don't lose water, we poison it.

    And really, we should be on desalinated water by now anyway. We really don't have to do anything more than collect what falls out the sky out over the oceans.

    Alternately, we could do what I did, namely factor in available fresh water supplies in choices about where we live and even more importantly grow crops and livestock, favoring "right near huge amounts of fresh water" over "in the middle of a friggin desert". That's what humans largely did before modern times, after all.
