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.
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.
