A mod for Minecraft that adds carbon emissions using AMEEconnect to get real scientific data from the IPCC. When you burn some wood in a furnace, the mod calls out to AMEEconnect to do a calculation, and adds the result to a tracker in-game. As the carbon ticks up, the environment gets more and more polluted as the skies go dark and the clouds come down.
