"You Can Kiss Much of It Goodbye"

"Put it all together, and the prospect is for a dramatic change in the mix of California produce and overall output. The UC paper foresees a decline of more than 40% in avocado yields, and as much as 20% in almonds, table grapes, oranges and walnuts. (Wine grape yields will be generally unaffected, but their quality might be compromised.)
"Disruption is already evident with some crops in some regions, the paper notes—in truth, dealing with natural variations in weather always has been the hallmark of California farming—but that's nothing compared to what lies ahead. 'The increased rate and scale of climate change,' the researchers say, 'is beyond the realm of experience for the agricultural community.'"

Michael Hiltzik in the Los Angeles Times discusses the impact climate change will have for California agriculture.
