Solar geoengineering represents a global case of environmental problem shifting, as the implementation of the technology would have effects worldwide. The nature and distribution of these effects are highly uncertain because of the complexity of the Earth system to which it would be applied. In addition, the use of this technology is difficult to regulate in an equitable and effective way under current global political configurations. This would raise important questions about the decision-making process, the location, intensity and timing of implementation, and the responsibility for unforeseen adverse consequences. It is clear that the risks posed by the technology would be unevenly distributed, raising questions about the legitimacy of the decision-making process. 

Sulfate injection into the stratosphere, a popular option in solar geoengineering debates, has been shown to have the potential to significantly damage the ozone layer near the poles, posing a threat to life on Earth.
