Why do animals in warm climates have big ears?
To expel heat more efficiently. In the case of animals such as the fennec fox, those large ears have a large amount of blood vessels close to the skin which allows heat to dissipate more quickly. In the case of animals such as elephants (particularly African elephants, who have larger ears than their Asian cousins), the ears also keep the animal cool by acting as a fan of sorts when the elephant waves them back and forth.
Why does a fennec have long ears to live in the desert?
Fennecs have large ears, in part, to help dissipate heat. No doubt, they benefit by hearing well also. Warm-blooded animals in hot climates often have larger extremities and appendages than their counterparts in cooler climates. This is a principle called "Allen's Rule," named for Joel Asaph Allen, who first formulated the principle in 1877. See http://en.wikipedia.org/wiki/Allen%27s_Rule for more information about Allen's Rule.

How does an elephant's ear stay warm?
The large ears of an elephant are serve the same function as a car engine's radiator. Behind the ears there is a large amount of blood vessels. Warm blood passing through these blood vessels is cooled before recirculating throughout the elephants body. This is why elephants seem to always be moving their ears. The fanning motion helps to cool the blood.So a more accurate question would be how they keep their ears from getting too warm.
