EARTH Magazine: California: A Profusion of Drought Restrictions with Varying Results

At times last year, 100 percent of California experienced moderate to exceptional drought conditions; even after massive storms in December, almost 80 percent of the state was still under extreme drought, the second-worst category. The drought has been ongoing for a few years now, and last year, state and local officials created new drought restrictions designed to mitigate the effects. But whether these restrictions will make a dent in California’s water shortage amid the ongoing and historic drought remains to be seen.

Drought Basics

Extreme drought is part of natural climatic cycles around the world. Historic records and prehistoric reconstructions extending back 1000 years document that extreme droughts have occurred repeatedly in North America, sometimes for longer periods than even the most severe droughts of the 20th century.[1] Research on climate variability is addressing how drought may impact the United States in the future.
