A Closer Look at California’s Drought
Jan 20, 2014, 12:33 PM
For now, California’s drought is reported to be the state’s worst in forty years, but climate scientists fear the weeks ahead could see it get even worse.
A map (right inset) produced by scientists at NASA’s Goddard Space Flight Center shows how dry California is compared to other states. Climatologists generate groundwater and soil moisture drought indicators each week, based on satellite data and other observations. This map, from January 13, shows the extent of the drought in California, with lighter colors indicating better soil saturation and darker colors indicating very dry land, compared to historical averages.
California’s drought has public health implications for both the state and the rest of the country for several reasons, including the potential for continued fires fueled by dry grass and trees, which pose risks such as fire injuries, smoke inhalation injuries and even death.
There could also be a produce shortage linked to the water crisis. The Associated Press has reported that city water managers in the state say the drought conditions may mean they have, on average, only about 5 percent of the needed water for consumers and farms in California. According to the U.S. Department of Agriculture, California supplies half of the fruits and vegetables consumed in the United States. Reduced crop sizes can also drive up produce prices because of a lower–than-usual supply and the need for imports, which can be more expensive because of shipping and other fees.
