Scientists have identified the most energy-efficient way to make clouds more reflective to the sun in a bid to combat climate change. 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.
