NASA, "Earth Science Program at UC-Irvine", and CBS news aren't exactly what I'd call unbiased toward a certain agenda...
Now granted California does have an issue pertaining to water. Agriculture IS important there, and California IS where (maybe?) most of America's fresh produce comes from because of the fertile, productive San Fernando valley.
Just flat-assed coming out and saying that "the world doesn't have enough fresh water" is just over the top... like someone's trying to sell fear.
Maybe, MAYBE, California doesn't have enough fresh water. Plenty of water here in my part of the world. Yes there is a certain neighboring state trying to get their mitts on some of it.
Maybe California could go buy some water somewhere else, like Oregon or Washington. There are these things called "pipelines", or "aquaducts". Also maybe they could decrease the number of people who are illegally consuming water there, that is to say being there illegally in the first place and consuming water at the same time.
Also it might help to ax some questions about the differing methods used for agricultural irrigation there, with some Israeli help...
Why provoke hysteria, "the world doesn't have enough fresh water left..."
That ain't gonna sell.
At my home in VT, I have plenty of fresh water. When the hose to my well burst earlier this winter, I had a garage and basement full of the wonderful fresh water. I would have sent it to Cali if I had known.
Instead, I pumped it into the back yard to eventually leach down to the water table for re-use.
