Prof. Yu Pengfei of JNU's Institute for Environmental and Climate Research is the corresponding author of a paper titled Towards practical stratospheric aerosol albedo modification: Solar-powered lofting, published in Science Advances. The paper proposes a practical stratospheric aerosol albedo modification plan. In response to climate change, a large number of scientists represented by Prof. Paul Crutzen, who won the 1995 Nobel Prize in Chemistry, have proposed a method of introducing large amounts of aerosol into the atmosphere. This method helps slow global warming and prevent sea ice melting and sea level rising, buying time for global carbon reduction. The paper proposes using a small amount of black carbon as a booster and heating the air by using black carbon aerosols to absorb light at the altitude existing ordinary aircraft can reach -- 13 kilometers -- thereby lifting a large amount of sulfur dioxise gas into the stratosphere.

This novel approach can effectively eliminate the technical bottleneck of stratospheric geoengineering and significantly reduce its implementation cost, the paper says.
