Marine Cloud Brightening is a reversible geoengineering method proposed to mitigate rising global temperatures. It relies on propelling a fine mist of salt particles high into the atmosphere to increase the albedo of clouds - the amount of sunlight they reflect back into space. This would then reduce temperatures on the surface, as less sunlight reaches the Earth.
