Geoengineering
Loosely defined as the intentional large-scale manipulation of the global environment; planetary tinkering; a subset of terraforming or planetary engineering. Techniques proposed include sulfate cannons, space mirrors, and huge buckets of white paint.
In 1996 Thomas Schelling wrote, “’Geoengineering’ is a new term, still seeking a definition. It seems to imply something global, intentional, and unnatural….” Geoengineering is the last gasp of a dying civilization.
