They remember the project Bill Gates want to cover the sun to cool the Earth, this summer the trials will begin. Based on Timer reports, a large balloon that will soon be launched in Sweden will spit out particles of calcium carbonate, essentially “chalk dust”.

The ” A controlled stratospheric disturbance test ”(SCoPEx) wanted to show that releasing this dust into the stratosphere could eventually divert some of the sun’s energy and lower the temperature of our planet.

Historic events

The balloon will be launched near the Arctic city of Kiruna, and this will be the first serious attempt to test whether global warming can be controlled by dim sunlight.

The study was carried out by scientists at Harvard University and funded by private donors, including the Microsoft founder, and was aimed at achieving that the Sun’s light is reflected externally. our planet’s atmosphere.

“SCoPEx is a scientific experiment aimed at improving understanding of stratospheric aerosols that may be related to solar geotechnical engineering” project page read.

Scientists opposed to this project believe that solar geotechnical engineering can bring urgent risks and extreme changes in weather patterns no different from current warming trends. now on.

On the other hand, environmentalists are concerned that a “drastic” change in mitigation strategies will become “green light” for greenhouse gases to continue to be released without any change. change in current consumption.

Based on Timer Some critics of the project argue that studying this kind of “solar geotechnical engineering” could backfire by giving politicians an excuse to delay reducing greenhouse gas emissions.
