Abstract
Solar radiation management (or geoengineering) can be used to deliberately alter the Earth's radiation budget, by reflecting sunlight to space. This has been suggested as a response to Anthropogenic Global Warming, to partly or fully balance radiative forcing. Approximately 22% of sun-like stars have Earth-like exoplanets. Advanced civilisations may exist on these, and may use geoengineering for positive or negative radiative forcing. Additionally, terraforming projects, may be used to expand alien habitable territory, or for resource management or military operations on non-home planets. Potential observations of alien geoengineering and terraforming may enable detection of technologically advanced alien civilisations, and may help identify widely-used and stable geoengineering technologies. This knowledge may assist the development of safe and stable geoengineering methods for Earth. The potential risks and benefits of possible alien detection of Earth-bound geoengineering schemes must be considered before deployment of terrestrial geoengineering schemes.
