Injecting microbubbles into water bodies or spraying sea foams onto the surface of seawater are theoretical solar geoengineering proposals which aim to reflect more sunlight back into space by altering the albedo (reflectivity) of water surfaces. These proposals aim to mimic and extend the lifetime of naturally-occuring whitecaps, which form on wave crests in windy weather, or white foam created as waves break on the shore, which are brighter and thus more reflective than calmer and darker water surfaces. The brighter the water surface is, the more of the sun’s energy will be reflected away and the less heat will be absorbed into the water.
