Question about Global Warming

[bonafide11]

Alright I should know this considering the amount of Civ IV I've played, but I used to never play the end game and now that I have began to play the end game, I realize why everyone hates global warming so much. Now nobody has used nuclear weapons in my game, the UN banned them a few turns after I finished the Manhattan Project so I was only able to build one and I am saving it. I also haven't built a single nuclear power plant because I can't stand the nuclear meltdowns and global warming. So I am relying mostly on coal power plants. But I keep getting global warming warnings.

Am I correct that nuclear power plants cause global warming, but NOT coal power plants? Also, if I don't build any nuclear power plants, but the AI does, will the AI suffer worse global warming than me? I conquered Pacal's land and noticed that quite a bit of his land was turned into desert, way more than the few tiles of mine. I think he was using nuclear power plants because he did not have coal, but I could be wrong. So will global warming affect him more than me if he is using nuclear power and I'm not? Or is it just completely random?

I wasn't aware the nuke plants caused GW...that's a bit absurd. GW, apart from the possibility of a meltdown, is pretty clean with regards to emissions. I would have thought that coal plants would cause GW given the amount that they pollute.

Surely someone knows the answer to this??

 

[KMadCandy]

this answer is from vanilla/warlords, afaik it hasn't changed for BtS:

global warming never happens until fallout appears on the map somewhere for the first time, either by a nuke launch or a nuclear power plant meltdown. after the first garbage has shown up, the game then does a random roll every turn (maybe only every X turns) to see if the planet gets a free bonus present of more.

"Am I correct that nuclear power plants cause global warming, but NOT coal power plants?"

yes. and not the plants themselves, but the meltdowns. the human doesn't get a warning when an AI plant has a meltdown so it can seem mysterious and often confuses people.

my understanding (unless this has been changed) is that building a hydro plant and/or 3GD does NOT take away the risk of a nuke meltdown, the way it does take away the unhealthiness from coal plants. which is completely lame but whatever.

"I think he was using nuclear power plants because he did not have coal, but I could be wrong. So will global warming affect him more than me if he is using nuclear power and I'm not? Or is it just completely random?"

once that "global warming" RNG event is triggered, it is completely random. doesn't matter who started it or anything. the AI loves to build nuke plants if it doesn't have coal. i hate global warming. i've been known to gift AIs coal hoping that will discourage them from making nuke plants!

Yep now that a plant has melted, Global warming is there to stay

Constant messages will appear showing you what land is turning to sand, it will never stop
Guess its why so many remove global warming

Global warming is seriously broken. I have one room mate who hasn't played Civ at all since he did an advanced start and wound up with GW right at the begining.

My only question is why this wasn't fixed? It's the worst part of the late game, and BTS was supposed to be set on making that experience better. So why no GW fix/change? That it is the same as it was in vanilla is . . . pretty much unacceptable. Maybe this should be posted to the bugs forum?

 

[Littlelisa]

Why wouldnt he play?

You can disable global warming real easy with 1 text change in a xml file
Do a search, theres many threads on it

Hopefully if they do Civ 5, it will have more advanced eco system with climate change and ways to combat it
I want to plant trees

How do you turn off global warming?

 

[Roland Johansen]

How do you turn off global warming?

In the file GlobalDefines.xml which can be found in
...\Civilization 4\Assets\XML
...\Civilization 4\Warlords\Assets\XML
...\Civilization 4\Beyond the Sword\Assets\XML

you change the value 20 into 0 in the following line of code.


<Define>
<DefineName>GLOBAL_WARMING_PROB</DefineName>
<iDefineIntVal>20</iDefineIntVal>
</Define>

You only have to change it in the version of the game that you're using (vanilla, Warlords or Beyond the Sword.

 

[Tellos]

Hmm I'll need to get help with this abit sometime I am not good with XML. But thanks

 

[Tellos]

Crap theres only a global warming terrain part in that file no PROB part. Also no value placed on it so maybe it got moved with the patch. [Gah nm friend sent me a pre modded file so yay]

If you couldn't find the line, then I guess you just didn't look very well, because it really ought to be there. Just do a search for GLOBAL_WARMING_PROB, that will make it easier.

Ok, step by step:

-Find the file in one of the folders that I mentioned in my previous post (depending on which version of the game that you use).

-Right click it and select 'open with'. Then select wordpad or notepad as the program with which you want to open it.

Press CTRL-f and enter GLOBAL_WARMING_PROB in the search box and click 'find next'.

-You should now find yourself positioned on the line that I mentioned in my previous post:

<Define>
<DefineName>GLOBAL_WARMING_PROB</DefineName>
<iDefineIntVal>20</iDefineIntVal>
</Define>

-Change the 20 into 0 and press CTRL-s (to save the file).

-exit wordpad or notepad.

You're done.

Note, if this is too hard, then ask one of your friends who is more knowledgeable about computers to help you as I can't describe it in more detail.

If you want to be able to revert back to the original game rules, then you should back up the original file somewhere before making changes or create a tiny mod out of this change.

Good luck.

Edit: I misread your post. It seems that you were already helped by a friend. I'll leave this here for anyone else that needs a more detailed instruction.

this should one of the changes to do in the next patches:

1) if they want to keep GW:

• an option that disables it

or

• instead of turning ice to desert instantly, turn ice to tundra, tundra to grassland, grassland to plains and so on ( like Civ 3 )

2) if they want to be a bit realistic

• turn GW into Nuclear Winter but with no desert into ice; again similar to Civ 3; desert to plain, grassland to tundra and so on

whichever they choose ( i wish they to choose number 2)

Spoiler :

but that is too much for Firaxis, now they only work hard to do terrible scenarios like AfterWorld

they could make events and even quests about this, greatly improving the game with minor changes

 

[Tellos]

No worries I found it later but it is not next to the other global warming part and I oftened passed over it cause theirs lots of other parts in the code. Found it sorry am a network engineer not a programmer code makes only so much sense to me and thats if it is in VB not XML. Anyways thanks agian and yeah I agree a option to more easily tunr it off would be better.

 

[Roland Johansen]

As long as there is no way to prevent global warming/nuclear winter and no way to combat the terrain changes, I can't see this as an interesting fun game element.

I agree that global warming as it stands in the game is stupid. It shouldn't be associated with nukes. Firing a lot of nukes will cause a nuclear winter, not global warming.

I think that if enough nukes are fired, three should be a random chance of a global winter. This could do something like reduce the food output of a certain percentage of land tiles in the world by 1 for 2 or 3 turns. The more nukes, the bigger the percentage and the longer the duration. This is the main threat of nuclear winters - reduced food output worldwide.

Global warming should be caused by either excessive unhealth worldwide or too many coal plants. Switching to global environmentalism should reduce or stop its effect. What it should do is melt ice, turn tundra to grasslands, etc like other posters have mentioned, so it would have good and bad effects like it could in real life. It could also have a chance of randomly damaging coastal improvements or buildings in coastal cities due to rising ocean levels. You could even have chances of animal or plant resources (deer, fish, wheat, etc) disappearing due to climate change if the global warming goes unabated. These should probably be in later stages of global warming.
