NEW DELHI: In the movie Kabhi Khushi Kabhie Gham, when Shahrukh Khan sang the song ‘Suraj Hua Maddham’ with outstretched hands, perhaps he and Anil Pandey, who composed this song, would not even know that the scientist took his words seriously to Sooraj. For the last two decades, concerns about global warming have been increasing continuously all over the world. There is no doubt that there is a need to cool the earth immediately. In such a situation, scientists have started considering dimming the sun to cool the earth. Which is called geo-engineering in scientific language.
Geo-engineering is the mechanical method of the world’s climate system to deal with global warming. There is a technique in the process of geo-engineering. Which is called stratospheric aerosol injection. In this process there is a fleet of airplanes, which release particles of aerosol. Due to which the rays of the sun get reflected and go to outer space and in this way the earth remains cold.
The skies can be slightly white due to SAI (Stratospheric Aerosol Injection), although this is not a cause for concern for scientists. Rather, if the earth cools, it means that there will be less amount of evaporation from the surface of the earth and there will be a change in the pattern of rain. Because of this, the ripple effect (a phenomenon or effect that does not stop once, but happens, and creates a chain of other events linked to one event) can occur in ecosystems around the world. But the nature of its effect depends on how the SAI (Stratospheric Aerosol Injection) has been used.
If the release of aerosols is not coordinated, then there may be a situation of excessive rain and drought at some places. Also, the risk of spreading diseases will increase. Not only this, due to SAI, natural disasters can also increase. If this happens, then the spread SAI will have to be adjusted immediately. So that extreme weather activities can be stopped. Apart from this, it can also damage the ozone layer. Also, due to the weakening of the sun’s rays, photosynthesis will not happen. Due to which the plants will not grow and along with the forests, agriculture will also suffer. To put a stop to this, a group of 60 experts has written an open letter. In which it has been said that this technology is as dangerous as human cloning and chemical weapons, which are not needed.
Experts say that if this is done, it will take many decades to improve it. It means tampering with nature in a terrible way. The consequences of which will be very terrible and if it is stopped suddenly, then to keep the earth cool, the protective shield of aerosol has been made. That greenhouse gas collected in the atmosphere will hit the earth in one stroke. Due to this, the temperature of the earth will suddenly increase 4 to 6 times compared to the current situation. That’s why according to experts, it is good to sing the sun, but its side effects can be seen experimentally.
