_More_ fossil water may not be the solution we seek.
Granted, though, if 100 centuries' worth of water is really extractable, this may be pushing the problem so far into the future that we can buy a lot of timer for better solutions.
I think many knee jerk liberals haven't yet internalized this viewpoint, and don't (yet) have great answers to that question. (Or turn it around: if you think this is wrong, but don't have a good answer, that makes you a knee jerk liberal!)
PS: I say this as a centrist liberal.
