Ice Age

This mod causes snow to fall in all biomes, lowers their temperature and changes grass and foliage color.
It's not required client-side but not having it installed will cause the game to render the default precipitation for every biome.

Old version

Requires Fabric API 0.60.0 or above, and Fabric loader version 0.14.9 or above.
