geoengineering
Planetary-scale climate intervention
Geoengineering is the large-scale deliberate manipulation of Earth's climate systems to counteract global warming.
Proposals include injecting aerosols into the atmosphere to reflect sunlight, seeding oceans with iron to boost carbon-absorbing plankton, or capturing carbon dioxide directly from the air.
The term implies interventions so massive they treat the planet itself as something to be engineered: Critics worry geoengineering could have unintended consequences.
Most approaches remain theoretical or experimental.
