California farmers face dramatic weather changes

Ten miles outside of Modesto, in the farming town of Hughson just off Highway 99, the Duarte Nursery is at the front line of dramatic changes now under way in California's immense agriculture industry.

The family-run nursery, founded in 1976, is one of the largest in the United States, and there's a good chance the berries, nuts and citrus fruits eaten across the West began their journey to market as seedlings in Duarte's 30 acres of greenhouses, labs and breeding stations.
