Bear is one out in freezing region (7)

I believe the answer is:

siberia

I'm a little stuck... Click here to teach me more about this clue!

'freezing region' is the definition.
'Siberia' can be an answer for 'region' (Siberia is an example). I am unsure of the 'freezing' bit.

'bear is one out' is the wordplay.
'one' becomes 'i' (Roman numeral).
'out' indicates an anagram (out can mean wrong or inaccurate).
'bear'+'is'+'i'='bearisi'
'bearisi' with letters rearranged gives 'SIBERIA'.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for siberia that I've seen before include "'Region of Russia, famous for its long, cold winters (7)'" , "Russian far-east" , "Region to which Russian and then Soviet governments sent those considered disloyal" , "Frozen region of former USSR noted for prison camps" , "Arctic region" .)
