Climate change is threatening several of California’s most valuable crops. Recent studies suggest that warmer temperatures, and the associated reduced winter chilling period, could render California’s climate unsuitable for growing a variety of fruits and nuts. Insufficient winter ‘chill hours,’ defined as the cumulative number of hours below 45 degrees Fahrenheit, can disrupt pollination, delay flowering, lower yield, and reduce fruit quality. California orchards are predicted to experience less than 500 chill hours per winter by the end of the 21st century, which will impacts the yields of walnuts, pistachios, apples, pears, and stone fruits like cherries, apricots, nectarines, peaches, and plums.
