Poster's note: please contact me if you would like a copy. One thing I didn't think to put in this paper was using geoengineering as a response to a sun that's getting hotter. I'd be interested to know how this could be modelled - as it would seemingly involve turning the solar constant up and down in the model - clearly a pointless exercise! http://www.jbis.org.uk/paper.php?p=2015.68.369 Technical Note: Geoengineering on Exoplanets A. Lockley (2015), JBIS, 68, pp.369-371 Refcode: 2015.68.369 Keywords: Geoengineering, exoplanet, solar radiation management 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 [1]. Approximately 22% of sun-like stars have Earth-like exoplanets [2]. Advanced civilisations may exist on these, and may use geoengineering for positive or negative radiative forcing. Additionally, terraforming projects [e.g. 3], 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.
