You can’t wrap the sun with a finger, however, maybe with science and technology then yes. According to Forbes, Bill Gates is financing a project that would dim sunlight to “cool” the Planet.
The study is known as SCoPEx (Stratospheric Controlled Disturbance Experiment) undertaken by Harvard University scientists and has the goal of achieving that light of the sun is reflected outside the atmosphere of the planet.
The answer would be attained by spraying lots of CaCO3 (non-toxic calcium carbonate) into the atmosphere. The project page reads “SCoPEx is a scientific experiment to expand the knowledge of stratospheric aerosols that could be important for solar geoengineering.”

Test of Maneuver
The project will start to carry out analyses that so far consist of discharging a balloon with the scientific device, which will not spray CaCO3 but will play a role as a test of maneuver and to investigate operating and communications systems.
They intend to utilize a high-altitude balloon to carry an instrument bundle estimated 20 km into the atmosphere. When in place, a very little amount of substance (100g 2 kg) will be discharged to produce a disturbing air mass roughly one hundred meters in diameter and one kilometer long.
They explained that they will use the same balloon to assess the arising changes in the disturbed air mass, involving modifications of light scattering, aerosol density, and atmospheric chemistry.
What Could be Mistaken?
According to Forbes, scientific oppositions of this project think that solar geoengineering could bring inevitable hazards and severe changes in weather structures that won’t be any different than recent warming trends.
They also disclosed that environmentalists worry that a rapid change in relief strategy will open the door for greenhouse gases to continue being secreted without any difference in the present consumption patterns.
Harvard University’s professor of applied physics and public policy David Keith acknowledges much real skepticism of geoengineering. No one knows what will happen until the CaCO3 is discharged and then researched afterward. David and fellow SCoPEx researchers released a paper in 2017 indicating that the dust might recharge the ozone layer by responding with ozone-destroying molecules.

CaCO3 Required to Cool the Planet
Additional study on this and similar strategies could lead to a decrease in risks and enhanced efficacy of solar geoengineering strategies.
The precise amount of CaCO3 required to cool the planet is unspecified and SCoPEx researchers also cannot substantiate whether it is the favorable stratospheric aerosol for the job. The initial study indicates that the material has almost-ideal visual properties that would enable it to assimilate far less radiation than sulfate aerosols, resulting in considerably less stratospheric heating.
This is the goal of the investigation: the project’s lead researcher does not understand what the outcome might result in. The precise aerosol would not instantly affect the stratospheric chemistry at all but what it would do is litter absolute sunlight and therefore cool down the world’s temperature.
