Science Ships

The climate temps of all planets range from 0 (ice planet) to 100 (hot desert). A  climate  type 50 is the best at supporting all forms of humanoid life. The Crystalline and the native race of Siliconoids do best in hot desert climates.

There are three ship classes that are able to transform a planet's climate just by orbiting it. Each ship will change the climate type by 1 each turn.

Bohemian Class Survey Ship:
Will make planets warmer until  climate  type 50 is reached.

Eros Class Research Vessel:
Will make a planet cooler until  climate  type 50 is reached.

Onyx Class Frigate:
Will make any planet turn into a hot boiling pool of rock and desert (temp 100).
