They found problems in places as disparate as North Africa, northern India, northeastern China and the Sacramento-San Joaquin Valley in California. The results are redefining the field of hydrology, which itself has grown more critical as climate change and population growth draw down the world’s fresh water supplies.

"While Dr. Famiglietti says he wants no part of water politics, he acknowledged that this might be hard to avoid, given that his role is to make sure the best data about groundwater is available, harvesting and disseminating all of the information he can about the Earth’s water supply as aquifers dry up and shortages loom.
“Look, water has been a resource that has been plentiful,” he said. “But now we’ve got climate change, we’ve got population growth, we’ve got widespread groundwater contamination, we’ve got satellites showing us we are depleting some of this stuff.
“I think we’ve taken it for granted, and we are probably not able to do that any more.”

I wonder how water evaporation rates and oversaturation affect gravitational pull? Looks like there's more and more of it in the atmosphere and less on the ground. - 1 year ago

And a lot less on the ground...or at least where it is dropping is not necessarily where it is needed.

[[Above picture is of a geothermal plant that borders the Salton Sea. The mud that comes out of the geothermal pipes is so heavy-metal laden. My brother-in-law, a geologist who works for a company that does reclamation projects, evaluated a plant at the Salton Sea. His company wouldn't touch the reclamation job, and that company would do a reclamation project for Satan if the contract was lucrative enough.]]

Who is Dr. Famiglietti trying to kid. If you are involved in water, you are involved in politics. That's why I love water issues so much =)
Perhaps if he had been involved in the politics of water when it was easier to make a difference, before things had degraded so badly, we would not be where we are now.
Nothing irritates me as people who have the power to save the world and don't bother because they "don't like politics."
They have to snap out of it. We no longer have the luxury of tolerating their prissy-ass ways when it comes to getting their hands into the political mud to effect positive environmental change.
