Explanation:

• Cloud brightening is a phenomenon that occurs when aerosols are injected into clouds by natural events such as volcanic eruptions.

• Marine Cloud Brightening – Also called as cloud whitening or cloud brightening, it was originally proposed by John Latham in 1990 to control global warming by altering Earth’s energy balance.

• It is a solar geo-engineering technique that involves spraying sea salt into low-lying clouds to increase the reflectance of cloud cover that will reduce the amount of incoming solar radiation striking the surface.

• Spraying large quantities of microscopic seawater droplets will create extra droplets and make the cloud brighter.

• Sea salt scatters light directly and provides additional shade.
