With climate change, crops migrate north

Farmers have always dealt with the whims of Mother Nature. But now climate change is changing what they can grow and where they can grow it. 

The most unusual thing about Joe Franklin's 78-acre citrus farm is that it really shouldn't be where it is. "When I first started with it, people couldn't believe me when I told 'em it was grown right here in Georgia," they said. "They didn't believe me; 'Oh, no, you can't grow that here!'"

But Franklin now has 12,000 trees, growing fruit in the middle of Georgia you'd normally expect to find hundreds of miles south in Florida: Grapefruit, Meyer lemons, mandarins, mangoes.
