How much would it take? Well for one it would be 923 tiles of rail. 3077/3,3333 gives us 923.ĩ23 Coal was spent for the result "only a couple turns later do we get to stage 3 or higher with Climate Change" This means we can calculate the amount of Coal used to make those emissions. Coal is also the worst CO2 polluter, so we will use it, for benefit of doubt. Since coal is the first available strategic, and no oil is mentioned, and it is early industrialisation no Oil is likely. So 4000/1,3 = 3077 units of CO2 have been produced. So let's say 4000 on the dot, keep benefit of the doubt to the storyteller. So now we know that global emissions must have been 4000+ since it was stage 3 (2000+1000+1000). Then unless these civs have more than half the planet tiles and clean cut it all, deforestation was lower than 50%. THUS we can calculate BACK to the claims made for instance by the OP.Ī couple of civs hit industrialisation and began using strategics. Thus 30% deforestation is emissions x1,3 for the global emission sum. The score is given as a percentage, and acts as a multiplier. A Civ's deforestation does not come into play until the start industrializing. It's a chunk of the global amount of tiles. Each Civ as a score for the territory that have under their control. To get to Global emissions, you have to use global deforestation.ĭeforestation is removal of forest, jungle and marsh. Upgrading units also counts, and that is applied in the SAME turn, as opposed to all OTHER expendatures of CO2 strategics, that are on the turn-over.Īnd then we have laying down track, for a neat 1 Coal (+1iron) per tile. A neat trick, combine into corps, armies, fleets and armadas, because they all have the same upkeep. But they have an upkeep of 1 resource per turn as well. So what matters? Of course power production, where both Oil and Coal are 1 unit = 4 power. The ONLY thing that counts is that you are burning strategics. It does not matter HOW you contribute it (with a single small exception). It does NOT MATTER what you are using Coal, Oil or Uranium on, it contributes the same flat rate. Uranium is unknown but significantly lower. I have not been able to obtain clear data on how much is between stages, but it IS based on emissions, and the most likely number right now is 1000 between each stage.Įach coal has a weight of 3,3333 CO2. Stage 1 global warming is 2000 units of global CO2. The formula, on standard map size and standard speed for global warming is like this. Now I don't mind if people think that global warming is going on too fast or too slow, but if you want to discuss it, it should be on a factual basis, and not hyperbole and manufactured anecdote. There are some pretty bad claims in this thread.
