matt76 specifically mentioned zero as the current temp., and it's difficult to think of a "normal" situation in which you'd say "twice as cold as zero". This would seem to be an artificial construct designed to make a paradoxical-seeming question.

Hammer has hit the nail on the head, (pun intended), in that both �C and �F scales are arbitrary scales, and as such, the terms "twice as hot" or "half as cold" don't have any meaning. ie 10 �C is not 'twice as hot' as 5 �C.
The only correct way to approach this question is to use a scale based on absolute zero, (as per kempie, rojash, & squirrel's answers), and, since 'cold' is a lack of heat, not an entity in itself, make all references with respect to heat. (ie half as warm, twice as warm etc)
