Coffee Growers Face Climate Change

From the LA Times:

A mile above this rural mountain town, coffee trees have produced some of the world's best arabica beans for more than a century.
Now, farmers are planting even higher — at nearly 7,000 feet — thanks to warmer temperatures.
"We noticed about six years ago, the weather changed," said Ricardo Calderon Madrigal, whose family harvests ripe, red coffee cherries at the higher elevation. He sells beans to some of the most notable coffeehouses in the U.S., including Stumptown Coffee Roasters of Portland, Ore., and Ritual Coffee Roasters in San Francisco.
Standing among healthy coffee trees near the upper reaches of his farm, Calderon said he knows he is lucky.
Calderon is one of the few Costa Rican coffee farmers benefiting from the shifting weather pattern, while most of his fellow growers have found themselves on the losing end.
Yields in Costa Rica have dropped dramatically in the last decade, with farmers and scientists blaming climate change for a significant portion of the troubles.
