Temperatures

I think that temperatures should be added into Minecraft to spice the game up. Since the new caves & cliffs update isn’t fully out, temperatures should be added for snowy mountains. For example, there should be a thermometer on the screen or something the shows you the temperature. It can be turned on and of just like coordinates. If you go to high the temperature would get very cold and you would start taking damage and it would 1 to 2 hearts. The only way to be able to travel far up high would be to combine leather armor with any color armor and you would end up with wool clothes, not armor. It does not provide any protection what so ever, but it will keep you warm when traveling up high in the mountains.
