Marine Cloud Brightening: Can Brighter Clouds Cool the Planet?

Brighter marine clouds could cool parts of the ocean. Climate scientist Dr. Jessica Wan explains marine cloud brightening, a proposed solar geoengineering method that would add sea-salt particles to low marine clouds. Learn how stratocumulus clouds reflect sunlight, what climate models suggest about regional cooling, and why scale, uncertainty, side effects, and governance matter. The episode treats marine cloud brightening as a research question, not a ready-made climate solution.
