As quite a few Aurora campaigns have some sort of disaster in the background fiction, I though it might be fun to actually simulate some in the game. The first two optional disasters will be in v4.3 and involve the Sun heating up or cooling down over time. The heating/cooling will take place during the 5 day increments and the temperatures of all the planets/moons, etc will be affected, meaning you will have a limited time to get off the Earth before it cooks/freezes. Of course, you could use terraforming to try and stave off the inevitable or move to other planets within the solar system that may become more habitable for a time. I thought this might add some extra fun to Earth-based starts
The alternative is 1% per year progressive, using a percentage of 1% in each 5-day increment based on time passed. That would speed up the rate of increase in temperature.
I'll think about some other disasters that I could add in the future
