Researchers from Harvard University are planning to spray in the particle stratosphere, reflecting the sunlight to temporarily reduce the heating of the planet and use this technology to combat global warming.
The team of scientists intends to spray calcium carbonate at an altitude of 20 km above the ground level with controlled air probes. During the first experiment on the territory of the United States, several small cylinders of the substance will be issued to the atmosphere. Tests are scheduled for the first half of 2019 and will cost $ 3 million after spraying calcium carbonate, the probes will turn to observe the dispersing of the particles.
This experiment will be the first experiment on geo-engineering conducted outside the laboratory. Although because of a small scale, it will not have a significant impact on the earth’s atmosphere, but environmental organizations will closely monitor its move, since even minor climate change can lead to the colossal consequences of a planetary scale.
With global warming, you can fight by reducing the amount of light entering the surface of the Earth, reducing carbon dioxide emissions or its absorption from the air. Among scientists are still working on
The Harvard team says that the experiment is technically very complex and requires the exact work of the probes, correct spraying and even particles of a certain size, therefore, computer test models continue to improve. The main advantage of the technology is the temporary nature of changes and relatively low costs under global use, since this calcium carbonate particles will effectively reflect the sunlight to two years.
