This 7DTD mod changes the temperature to be colder the higher up you go. This is a standalone mod that only modifies the weathersurvival.xml file. It should work well with the other Punishing weather themed mods.
Warning: This mod may not play well with other weathersurvival.xml modifying mods because it adds a table of same named node properties of temperatures.
The forum topic of the mod is here.
