Within the controversy surrounding geoengineering, the actors involved fall in to one of two categories: those in favor of furthering the research and those who are opposed to all forms of geoengineering. It is uncommon to find an individual who is educated on the topic of geoengineering that does not have a strong opinion toward it.
Another category of actors involved with this controversy are those non-human actors. In this controversy the non-human actors are those that occur naturally in the world and those that serve as the basis for this controversy.
