Recent findings suggest that marine cloud lightening up, a technique of increasing cloud cover to cool the Earth, might be more efficient than previous designs recommended, using substantial cooling results however functioning as a short-term mitigation instead of an option to worldwide warming.
New research study recommends that cloud “engineering” may be more efficient at cooling the environment than formerly thought, due to the production of increased cloud cover.

To examine the phenomenon, the scientists produced a ‘natural experiment’, utilizing aerosol injection from the gushing eruption of Kilauea volcano in Hawaii to study the interactions in between these natural aerosols, clouds, and environment.
