Injecting five million tons of diamond dust annually into the stratosphere could lower the Earth's temperature by 1.6 degrees, potentially easing global warming,El.kz cites Anadolu.
Researchers were inspired by past instances where volcanic smoke and particles cooled the Earth by covering the atmosphere.
They believe diamond dust in the stratosphere could reflect sunlight and reduce heat.
In the fight against global warming, scientists explored controversial geoengineering solutions, including dumping iron into oceans and launching mirrors into space to cool the planet.
One of the proposals is a solar geoengineering method known as "stratospheric aerosol injection," which involves spraying aerosols into the stratosphere to create a cooling effect similar to a volcanic winter, to reduce the sun's effect.
