Individual fog change

i was searching but without any result... what i need is a personal fog for players, cause im making a multiplayer third person construction game like minecraft, and i want to change the fog color and density when the player go to the ocean or rivers or lakes or whatever... but i was thinking.. if i simply manipulate the global fog values that will change the entire scene, so if a player is peacefuly walking across some mountain and suddenly the sky changes, a magical dark blue fog appears and he will be like "WTF did just happen here?" and of course when someone leaves the water the sky will be normal again, so imagine a few players leaving the water and others swiming... there will be a total chaoss in the sky... so after all that text my question is:

Is it possible to every different player have their own instance of a global fog?? if its not, how can i achieve this? an underwater fog for each one?
