You remember the project with which Bill GatesI wanted to cover the sun to cool the earth. Well, this summer the tests will begin. As reported The timesA large balloon will soon be launched in Sweden that will spit out particles of calcium carbonate, which are essentially chalk dust.
The “Stratospheric controlled perturbation experiment”(SCoPEx) wants to prove that the release of this dust into the stratosphere could ultimately divert some of the solar energy and lower the temperatures of our planet.
The balloon will be launched near the arctic city of Kiruna and would be the first serious attempt to test whether global warming can be kept under control by dimming sunlight.
The research is carried out by scientists from Harvard University and funded by private donors, including the founder of Microsoft. The aim is to achieve that sunlight is reflected from the atmosphere of our planet.
“SCoPEx is a scientific experiment to improve the understanding of stratospheric aerosols that could be relevant for solar geoengineering,” says the project page.
Scientific opponents of this project believe that solar geoengineering could bring compelling risks and extreme changes in weather patterns that would not differ from current warming trends.

On the other hand, environmentalists fear that a “dramatic” change in the mitigation strategy will turn into a “green light” for further greenhouse gas emissions without changing current consumption patterns.
In accordance with The timesSome critics of the project argue that work on this type of “solar geoengineering” could backfire by giving politicians an excuse to delay reducing greenhouse gas emissions.
