As the climate warms, sources of the water so critical to life everywhere on Earth are drying up.
By the end of this century, communities dependent on freshwater from mountain-fed rivers could see significantly less water, according to a new climate model recently released by University of California researchers.
For example, people who get freshwater from the Kings River could see a 26 percent decrease in river flow.
When people get near California’s giant sequoias, they usually look up.
