Planetary Climate

Every planet has a specified climate that impacts what the population will produce, as well as the maintenance cost for buildings built there. The complete list of climates can be found below. Some climates are "Special" indicating that they will only be found on a single world within the galaxy.

Terraforming

Terraforming can produce either an improved version of the original climate, or a different climate entirely. It is not clear what determines whether a planet will become an improved version of the current climate, or will change. The list includes the percentage chance of each outcome climate, when the climate of a planet shifts. Special worlds cannot be terraformed.

Beware that Terraforming does not always result in a "better" world.
