Because cold slows down the hydrogen and Oxygen atoms (H2O) in water, they become more compressed (frozen). Heat, or temps above 32 degrees, tend to excite these atoms causing them to move apart thus causing them to melt.
It only melts IF the environment is above the freezing point...

in Antarctica it might never melt.
Ice cube melts because when the room is in its normal temperature that is bout 25 degrees it melts the ice and when the ice melts a few minutes later it evaporates
