Scientists Inject Salt Aerosol Into Clouds in Controversial Climate Experiment
Atmospheric scientists began spraying sea salt aerosol into the atmosphere from Alameda, California, on April 3. The scientists are with the University of Washington’s Marine Cloud Brightening (MCB) Program, an international initiative. MCB lead scientists Robert Wood and Sarah Doherty, both from the University’s Department of Atmospheric Sciences, say their experiment is being conducted to investigate whether brighter clouds can reduce global warming by increasing the reflection of solar radiation. “Atmospheric particles, also called aerosols, can have a strong effect on sunlight reflection by clouds,” said Ms. Doherty in an April 2 statement. “As humans make changes to aerosol emissions, we need a stronger scientific understanding of these effects in order to better understand the potential risks and benefits, and to limit unintended effects.”...
