I've seen many discussion threads about global warming and I can't remember someone defending it as being a great mechanism to simulate real world global warming. However, there are quite a lot of players who just don't want to mod their game because they want to stick with the standard rules or because they don't have enough general computer knowledge. There are also quite a lot of players who have changed the global warming mechanisms. Usually a bad experience with the mechanism during a game is more convincing than someone describing the mechanism in theory.
It's quite easy to for instance remove global warming from the game. The file GlobalDefines.xml which exists for every version of the game (vanilla, Warlords and BTS) holds many parameters that effect the game. One of them is:
Code:
<Define>
<DefineName>GLOBAL_WARMING_PROB</DefineName>
<iDefineIntVal>20</iDefineIntVal>
</Define>
Changing the 20 to 0 removes global warming from the game.
The file is located in:
...\Civilization 4\Assets\XML
...\Civilization 4\Warlords\Assets\XML
...\Civilization 4\Beyond the Sword\Assets\XML
depending on the version of the game that you wish to change. It's preferable to create a tiny mod out of it than changing the original file(s). If you do change the original files, then make a backup of the file first so that you can revert back to the original files.
You can copy the file from the main game directory to a similar position in the customassets folder (so under the xml directory) and then change the 20 into 0 in that copied file to remove global warming. Files in the customassets directory are looked at first when the game is looking for game rules. It's not a real mod which I prefer but it's an easy way to do it and easily reversible.
