Biome Dependent Atmosphere/Lighting

It would be a very interesting and realistic feature if there was biome dependent lighting and atmosphere. Some examples for this would be something like slightly darkening the sky and adding a hazy effect in a swamp or thick fog when it rains in a jungle. This would greatly improve the experience and give the biomes a lot more variety, even leading to more dramatic looking builds and landscapes. Just a few small features that would really make the biomes more rich and exciting, and improve upon the exploration aspect of the game.
