Writes Modern Farmer, the researchers analyzed 100 years changes in precipitation, temperature and fraction of snow cover in the Sierra Nevada (which provides farmers with water) and their impact on the most valuable for this region crops: grapes, oranges, apricots, peaches, nectarines, plums, avocados, almonds and walnuts.
In General, the trend frightening. For example, in the state of increased maximum and decreased minimum temperature, has also become more unpredictable rainfall, less snow, there were numerous droughts, floods and other weather anomalies. Since 1880, the global temperature in the state rose by 1.4 degrees, and from 1975 to 2016 it began to grow by 1.2 and 2.2. In addition, from October 2011 to March 2014 in the state was the driest 30-month period from 1895, when he conducted the first study. While the least precipitation was primarily in southern California.
Climate change has a different impact on different crops and areas. For example, the most vulnerable Valley Salinas Valley San Joaquin, and the wine belt of Northern California, to a lesser extent. Scientists expect that the grapes will keep the yield, but the berries will deteriorate the flavor and change the color. In addition, can grow alfalfa crop and fall – oranges, avocado and almonds. Also, according to the calculations of scientists, in the next 25 years will not have areas suitable for growing stone fruit.
