Siberian
Relating to or originating from Siberia, a large region in Russia. It is often used to describe extreme cold.

The adjective 'sibirisch' (Siberian) is derived directly from the geographical name 'Sibirien' (Siberia). So it literally means 'originating from Siberia' or 'belonging to Siberia'.

The Siberian tiger is an endangered species.
'Sibirisch' (Siberian) is very often used figuratively to describe extreme cold. The most common collocation is 'sibirische Kälte' (Siberian cold).
Zieh dich warm an, es herrscht eine sibirische Kälte draußen.
Dress warmly; there is a Siberian cold outside.
Like other adjectives, 'sibirisch' (Siberian) can stand before a noun and is then declined, or it can stand unchanged after verbs such as 'sein' (to be) or 'wirken' (to seem/appear).
Eine sibirische Kältewelle zog über das Land.
A Siberian cold wave swept across the country.
Russian
'russisch' and 'sibirisch' can both have to do with Russia. 'russisch' is the general term for Russia, its language, culture, or people. 'sibirisch' refers only to Siberia, a specific large region in Russia. In addition, 'sibirisch' is often used to describe very intense cold. The words can be confused because Siberia is part of Russia. But 'sibirisch' is much more specific than 'russisch'.
