Scientist say California's current drought appears similar to events during a prolonged dry spell that occurred here long before the first Europeans arrived.
And the expected return of such conditions would mean more extreme weather, including larger floods and deeper droughts, said Lynn Ingram, a UC Berkeley professor in the Department of Earth and Planetary Science at UC Berkeley.
"The past 150 years have been wetter than the past 2,000 years," Ingram said in a recent video for the UC California Institute for Water Resources.
Studies at Mono Lake by researcher Scott Stine of California State University East Bay have found evidence of a dry spell from 1,800 to 600 years ago.
Since the 1960s, the state has seen gradually increasing temperatures.
Ingram said scientists believe the warming will continue.
