There are the three starships that are able to transform a planet's climate just by orbiting it. Each starship will change the temperature by 1°W each turn.
Starships which are transforming the climate of a planet will report the temperature of the surface of the planet to the starship's controller each turn. Terraforming is performed after starship movement.
This ability is automatically activated when the starship is in orbit of a planet with a temperature within the range that the ship can modify. No special Mission or Friendly Code is required to activate this ability.
