Marine cloud brightening, also known as marine cloud seeding or marine cloud engineering, may be a way to make stratocumulus clouds over the sea brighter, thus reflecting more sunlight back into space

…aerosol injection (SAI), in which small reflective particles would be introduced into the upper atmosphere to reflect sunlight. Other approaches include marine cloud brightening (MCB), which would increase the reflectivity of clouds over the oceans, or constructing a space sunshade or a space mirror, to reduce the amount of…
Ships churning across the Pacific Ocean left this cluster of bright cloud trails lingering in the atmosphere in 2012. The narrow clouds, known as ship tracks, form when water vapor condenses around tiny particles of pollution that ships either emit directly as exhaust or that form as a result of gases within the exhaust.
