The experiment in Alameda did not involve brightening clouds; it was only testing the way sea-salt particles emitted through a spraying device behave under different atmospheric conditions.

The narrative is also steeped in hope and moral urgency, motivating a willingness to explore a diversity of experimental and controversial new technologies -- from genetic editing to cloud brightening.
