Scientific American: Geoengineering Test Quietly Launches Salt Crystals into Atmosphere.
A solar geoengineering experiment in San Francisco could lead to brighter clouds that reflect sunlight. The risks are numerous.
The experiment, which organizers didn't widely announce to avoid public backlash, marks the acceleration of a contentious field of research known as solar radiation modification. The concept involves shooting substances such as aerosols into the sky to reflect sunlight away from the Earth.
The move led by researchers at the University of Washington has renewed questions about how to effectively and ethically study promising climate technologies that could also harm communities and ecosystems in unexpected ways. The experiment is spraying microscopic salt particles into the air, and the secrecy surrounding its timing caught even some experts off guard.

"The idea of interfering with nature is so contentious, organizers of Tuesday's test kept the details tightly held, concerned that critics would try to stop them," the Times reported. The White House also distanced itself from the experiment, which is being conducted with the cooperation of a Smithsonian-affiliated museum.
"The White House distanced itself from this experiment." Shocker! We know if asked about it, Kareem Abdul-Jean Perrier will, "refer to the University of Washington and the Smithsonian for further details."
"The world is our guinea pig!" These kinds of experiments need to stop.
