Researchers from Harvard University plan to spray particles that reduce sunlight into the stratosphere to temporarily reduce the heating of the planet and use this technology to combat global warming.. The team of scientists intends to use controlled air probes to spray calcium carbonate at an altitude of 20 km above ground level. In the first move over the territory of the United States in the experiment, several small cylinders of the substance will be released. Tests are scheduled for the first half of 2019 and will cost $ 3 million. After spraying the calcium carbonate, the probes will deploy to observe the dispersion of the particles.. This experiment will be the first geoengineering experiment conducted outside the laboratory. It does not significantly affect the earth’s atmosphere… Global warming can be combated by reducing the amount of light entering on the surface of the earth, reducing carbon dioxide emissions or absorption from…
