*evil grin - trying to think like Tim*
Think about this:
Normally every planet-star system is in its equilibrium (let's assume
that for simplicity), and than mankind (or birdkind, stormerkind and
so on) comes and unbalances the equilibrium, depending on the industry
built on the planet. The climate can go up or down, depending on the
specific effects (which we don't need to know here).
Speaking in game rules - just a first idea:
If the sum of (factories, (labour) farms, (labour) mines, public and
military spaceport, and some other buildings of course) reaches a
certain limit (a spaceport counting more than a single farm of
course), there's a chance (in every turn) that the climate changes. If
the temperature goes up or down should be chosen the first time when
the climate changes (that's might be the difficult part here). But
there's a little chance that the direction of the temperature drift
can change also.
(Note: If farms are not only cropping farms but also stock-farming
then the methane 'exhaust' of stock is indeed a bad influence to
climate)
Certain buildings should be able to stabilize the climate (lower the
chance) of course. Terraformer can do this perfectly, but some other
buildings should have a similar (but smaller effect), and these should
be available to everyone. Also there should be the possibility to
spent money to save the earth .. hum... the planet I mean *g*. Perhaps
like the crime thing (where the player cannot choose to spent money).
Hmm, the chance might also depend on the race: Think about the Feds
and then about the Borg or Stormer.
The effects should be not dramatic, at least not more than it is now.
But it would be a bit more rational and understandable - and
preventable also.
