In this article, Christopher J. Preston compares the culpability for any unintended harms resulting from stratospheric aerosol injection versus culpability for the unintended harms already taking place due to carbon emissions. To make this comparison, both types of unintended harms are viewed through the lens of the doctrine of double effect.

In this response, Holly Lawford-Smith points to the issue of agency in Christopher J. Preston’s analysis. She argues that while the harms of geoengineering will be caused by culpable agents acting intentionally, the harms connected to climate change emerge out of the uncoordinated actions of billions of people.

While Harvard’s research program could help us to better understand solar geoengineering, they should be careful not to oversell their program at the cost of broader climate action. Likewise, we should be careful not to think their program provides an excuse to avoid rapidly reducing our dependence on fossil fuels and carbon emissions.
