• Recently, scientists are testing a geoengineering technique called Marine Cloud Brightening (MCB).
• The Marine Cloud Brightening Program is an open collaboration of atmospheric scientists and other experts to study how clouds respond to particles (or aerosols) in the atmosphere.
• Scientific studies indicate that aerosols of the right size and concentration could significantly increase the reflectivity of specific types of clouds. MCB is a scientific initiative which explores this.
• By releasing tiny aerosol particles into the atmosphere, researchers aim to enhance cloud brightness, leading to increased sunlight reflection.
This programme aims to:
➡ Better understand the present-day effects of pollution aerosols on clouds.
➡ Investigate whether aerosol particles made from sea salt could be used to intentionally reduce near-term climate warming.
➡ Understand the benefits, risks and efficacy of the intentional use of aerosols to reduce warming.
