Simulation of geoengineering volcano shows desired surface cooling

•, brian wang

Aerosols would be dispersed from balloons or airplanes at approximately 15 and 30 degrees latitude on both sides of the equator. The desired results would be reduced surface warming and a positive change in the temperature gradient.

Researchers ran 20 computer simulations to demonstrate the impact of adding sulfate aerosols to the stratosphere in the proposed manner.

The models showed the desired cooling impact.

But it is not perfect. There would be reduced global rainfall. The models showed that the changes in rainfall would not be uniform, either; some areas would get less than others. And as some of those areas, such as the North Atlantic, received less rainfall, the ocean would experience an increase in salinity, which would make the water denser.
