The Washington Post posted a story yesterday linking recent variations in climate to shortages in leafy greens. According to the article, “the shortage, first reported by NPR, is the result of two separate phenomena in Arizona’s Yuma County and California’s Salinas Valley, the two places where the United States grows most of its leafy greens. In Yuma, the lettuce harvest, which usually runs from November to April, wound up early because of unusually warm weather. And in central California, which typically picks up the harvest once Yuma is done, heavy precipitation delayed some plantings.” You can read more about the links to a warmer climate here.
