When it comes to the future of water, "we are, on many levels, completely and totally hosed.”

The water cycle itself is changing. As temperatures rise, evaporation and precipitation

increase and the atmosphere holds more water. ”Expect extreme extremes” and more conflicts over water.- Jay Famiglietti, Director, UC Berkeley, Center for Hydrologic Modeling
