Planetary engineering is the application of technology for the purpose of influencing the global properties of a planet. The goal of this theoretical task is usually to make other worlds habitable for life.
Perhaps the best-known type of planetary engineering is terraforming, by which a planet's surface conditions are altered to be more like those of Earth. Other types of planetary engineering include ecopoiesis, the introduction of an ecology to a lifeless environment. Planetary engineering is largely the realm of science fiction at present, although some types of climate change on Earth are recent evidence that humans can cause change on a global scale.
Terraforming
Terraforming is the hypothetical process of deliberately modifying the atmosphere, temperature, or ecology of a planet, moon, or other body to be similar to those of Earth in order to make it habitable by humans.
Geoengineering
Geoengineering is the application of planetary engineering techniques to Earth. Recent geoengineering proposals have principally been methods to tackle human-induced climate change by either removing carbon dioxide from the atmosphere (e.g. using ocean iron fertilisation) or by managing solar radiation (e.g. by using mirrors in space) in order to negate the net warming effect of climate change.
