Researchers from the U.S. have proposed that billions of tonnes of dust can be launched from the moon to a point in space where the earthβs and the Sunβs gravitational fields cancel each other out.
The dust will be 'parked' there, casting a shadow on earth and dimming sunlight to offset carbon emissions. While aerosols in the stratosphere do have a cooling effect, the consequences of dimming the amount of incoming sunlight with stratospheric aerosols are uncertain.
Climate models are still inadequate at estimating the precipitation response to solar radiation perturbations at all scales. Any projections related to changes in rainfall, as a result of blocking sunlight, will be highly uncertain.
Many natural and social scientists have expressed grave concerns about solar radiation management (SRM) science and governance. Who will decide when and where to deploy aerosols, and how much?
Compensation for the accidental outcomes of SRM will be contentious.
Therefore, a major caveat of the aerosol-loading approach is that there will be a rebound effect once spraying stops and the aerosols are washed out of the atmosphere.

7/ So, when the temporary cooling effect is on, we must still reduce emissions.
If we donβt, the cooling effect will end and the heating period will recommence.

8/ What do you think about this research? Do you think this approach is practical? Do comment and share!
That's a wrap!
