Area around the North Pole (6)
I believe the answer is:
arctic
'area around the north pole' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for arctic that I've seen before include "Freezing cold like North Pole" , "-- Circle; -- fox" , "Northernmost regions" , "Area around the North Pole" , "Polar region" .)
