Due to the terrible effects of global warming, scientists decided to find a practical solution through developing aerosols. A new study has demonstrated that releasing into the air the equivalent of antacid could be the appropriate solution. Even if previous studies were revealing opposite results, a new research determined experts to believe that deploying a calcium carbonate aerosol into the air may help to cool down the air, without harming the integrity of the ozone layer.
The Paris climate agreement established last year that the primary purpose is to maintain global temperatures at a constant level, no higher than 1.5 degrees Celsius over the limit. The reduction of greenhouse gas emissions is the absolute key to achieving this goal. Nevertheless, some specialists claim that there are efforts which can be made to determine the reduction of dangerous risks.
A previous idea developed a while ago was to geoengineer the planet to simulate the cooling effect which occurred in the air after the eruption of a volcano. A powerful explosion delivers large quantities of sulfur dioxide into the air. Scientists’ goal may be completed through releasing light-reflecting sulfate aerosols directly into the stratosphere.
Nevertheless, this experiment imposes some risks considering the fact that they would generate sulfuric acid known to harm the ozone layer. A new study conducted by researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) implied a similar experiment, but without jeopardizing the safety of our planet’s ozone layer through the release of sulfur dioxide.
David Keith, who is Professor of Public Policy at the Harvard Kennedy School but also a professor of Applied Physics at SEAS, argued that the research in solar geoengineering which presented the option of using sulfuric acid which could harm the layer of ozone was considered to be the only idea which produced a serious tension.
The new research was seen as a significant step in reducing and analyzing various risks imposed by solar geoengineering. Previous studies have concentrated on determining ways of limiting the damage of the ozone layer by implementing the use of non-reactive aerosols. Frank Keutsch, the co-author of the study, stated that their team wanted to use a highly reactive material which at the same time would be able to avoid the damage of the ozone layer.
