"In order to study the conduct, observation, or defence associated with such attacks, a range of potentially practical weapon and defence technologies are discussed. These are: altering the radiation budget of a planet so as to substantially change its temperature; introducing invasive species to transform the biogeochemistry; and using orbital perturbations of comets and asteroids to cause collisions, or to move the planet to an unstable or uninhabitable orbit."
