Yesterday, we attended a talk by Dale Jamieson, Director of Environmental Studies at NYU, on the ethics of global engineering. During his talk, he paraphrased UW Philosophy Professor Stephen Gardiner, on the topic of whether geoengineering is “cheap.”

Professor Gardiner has said that calling geoengineering “cheap” is like saying that surgery is cheap because a scalpel is inexpensive. It’s quite a memorable way to describe that anything is cheap if you don’t measure the costs of externalities and consequences.
