Fayil's Temperature Mod adds a temperature value to the player as well as the player's location. If the player gets too hot or too cold, they will suffer fatal effects unless they take measures to counteract the harsh climates. New blocks and items are added to help mitigate these effects, and temperature sources were added to some vanilla blocks as well.
