“You can’t cover the sun with one finger,” but maybe with science and technology, yes. In accordance with Forbes, Bill Gates funds a project that dims sunlight to “cool” the earth.

The investigation called “Stratospheric controlled perturbation experiment”(SCoPEx for its acronym in English) is carried out by scientists from Harvard University and aims to achieve that sunlight is reflected from the atmosphere of our planet.

This solution would be achieved by spraying tons of non-toxic calcium carbonate (CaCO3) into the atmosphere. “SCoPEx is a scientific experiment to improve the understanding of stratospheric aerosols that could be relevant for solar geoengineering,” states the project page.

The project will begin by conducting tests that previously consisted of releasing a balloon with scientific equipment that does not spray CaCO3 but serves as a maneuvering test and examines communication and operating systems.

“We are planning to use an altitude balloon to lift an instrument package about 20 km into the atmosphere. Once attached, a very small amount of material (100 g 2 kg) is released to create a disturbed mass of air that is approximately one kilometer long and one hundred meters in diameter. Then we will use the same balloon to measure the resulting changes in perturbed air mass, including changes in aerosol density, atmospheric chemistry, and light scattering, ”they explain.

What could go wrong?

In accordance with ForbesScientific opponents of this project believe that solar geoengineering could introduce substantial risks and extreme changes in weather patterns that would not differ from current warming trends.

They also explain that environmentalists fear that a “dramatic” change in mitigation strategy will turn into a “green light” for further greenhouse gas emissions without changing current consumption patterns.
