Familiar with meteorology, they know that at an altitude of 6 to 12 km ice crystals form cirrus clouds that affect the reflectivity of our planet. A team of scientists from the University of Geneva recreated atmospheric ice-forming conditions in the laboratory. They managed to create tiny ice crystals with a diameter of 90 micrometers wide.
When they hit the laser beam, they explode with the formation of tiny plasma balls, which causes the ice to evaporate. Evaporation, in turn, generates a shock wave that breaks the crystals into even smaller fragments.
On the scale of the Earth’s atmosphere, this will lead to the formation of huge massifs of tiny ice dust that will reflect sunlight back into space, preventing the Earth from overheating .
Researchers believe that this method can be used to increase the reflectivity of the Earth (the albedo index) in the upper atmosphere, thereby regulating the climate of the planet.
