In California, rains happen in the winter and crops (mostly) grow in the summer. The Sierra Nevada snowpack is the "bank" that stores this precipitation for 3-4 months until it is needed to grow food in the Central Valley. If temps are too warm for the snow to persist, that water is essentially lost unless it is stored in dams. So, climate change is a huge loss for us.
