The Alameda vote ends the city's participation in the CAARE project, which aims to explore marine cloud brightening as a method to combat global warming.
Local officials halted the experiment last month due to permit issues, raising concerns about public engagement and regulatory compliance.
Experts generally support the experiment, but environmental groups oppose it, fearing it could lead to widespread geoengineering practices.
Key quote:
"Cancellation of this small experiment could add to public confusion about climate intervention research more broadly."

Why this matters:
The cloud-brightening technique involves spraying fine sea salt particles into the atmosphere to increase the reflectivity of clouds. By doing so, scientists aim to reflect more sunlight back into space, thereby cooling the Earth's surface. Proponents of the experiment argue that this method could provide a vital tool in the fight against rising global temperatures, potentially offering a temporary solution while broader carbon reduction strategies take effect. Alameda’s decision will influence the future of geoengineering research in the U.S., impacting global efforts to find viable climate solutions.
NASA researchers are using a technology straight out of a science fiction novel to track Earth's changing climate with greater precision than ever before: space lasers.
