Bill Gates working with scientists to stop heat by scattering dust in sky

Bill Gates working with scientists to stop heat by scattering dust in sky

Earth temperature gradually increasing. Now scientists are working to overcome this problem they are working on a scheme under which every day more than 800 large airplanes will take millions of tons of chalk soil 19 kilometers above the earth and sprinkle it in the stratosphere.

This dust will form a dust cover in the Earth's stratosphere and a large number of sun rays and heat will go back into space. This experiment can save the Earth from heating up to a great extent. It is not a garden shed builder, but Microsoft founder Bill Gates and Harvard University scientists are working on this project.

Scientists are not sure about the experiment yet

Initial testing of the scheme would cost around Rs 21 crore. Under this, a scientific balloon going 19 kilometers above the New Mexico desert will scatter about two kilos of lime. This will create an area of ​​about fifty kilometers long and 100 meters in diameter in the shape of a tube in the sky. The sensors on this balloon will then analyze the rate of reflection of the sun's rays due to this dust and the effect on the air around it.

However, this experiment is still prevented due to the fear that it may lead to a serious chain reaction and it does not lead to severe drought and storm conditions. There is also a fear that there will be damage to the ozone layer by spraying dust in the stratosphere.

The idea came from an eruption in a volcano

Lizzie Burns, a director of Harvard's team, admits that her idea is scary, but so is the change in the atmosphere of horror. That is why a panel of experts has been formed to study the potential hazards. The question is, where did the idea of ​​this scheme come from? It was originally inspired by the 1991 eruption of Mount Pinatubo volcano in the Philippines. However, the explosion had killed more than 700 people and left two lakh people homeless. However, this gave scientists the opportunity to study the changes in the stratosphere. At that time, the temperature of the world had decreased by half a degree for six months due to the dust spreading from it.
