Do root cellars work in hot climates?

Used mainly in the Northern states, below-ground storage chambers hold a fairly constant temperature, usually below 70 degrees. Stephens said the Florida climate is too hot and damp for traditional cellar storage. Crops stored underground would quickly rot.

Is a root cellar better than a fridge?
