UC Davis agricultural economists say climate change is affecting what crops are planted in California. Ed Joyce reports from Sacramento.
The study looked at 12 crops in Yolo County, using 105 years of local climate data and 60 years of county planting history.
UC Davis agricultural economist Dan Sumner says warmer winter temperatures would reduce "chill hours," potentially reducing yields for some crops, while extending the growing season for others.
And that could cause growers to change planting practices.
