There is no negative scale for degrees Kelvin in the conventional sense because no lower (colder) temperatures are possible. Zero degrees Kelvin is also called Absolute Zero; it is the temperature, in classical physics, at which molecular motion stops.

Negative temperatures are possible in systems which have a maximum amount of energy they can hold, and would be hotter than the hottest system with a positive temperature.

Funny thing is, the exact temperature, is not as fixed as people think. It keeps getting more defined, but the exact definition (in temperature) is still being tweaked on the small decimal places.
