There are certain scientists out there who came up with an unusual idea. According to them, blasting sulfate aerosols into Earth’s atmosphere might help cool down the planet. However, a recent study contradicts them by claiming that aerosols would only create droughts and even more hurricanes. In order to believably contradict the first idea, a team of experts ran a model to see what would happen. This model simulated how annually spraying aerosols in both hemispheres would affect the planet’s climate between 2020 and 2070.
It’s interesting that science seems to be supportive of this climate engineering method called stratospheric aerosol injection. It’s based on the idea that aerosols are creating a reflective layer over our planet. This layer would then block out part of the Sun and help cool down the Earth. It’s worth noting that this process is already happening naturally each time when there are volcanic eruptions.
Aerosols into the atmosphere might do more harm than good
The problem is that If we were to inject aerosols into the planet’s atmosphere, depending on the location, it might have different and damaging effects. If we sprayed aerosols in the northern hemisphere we would indeed decrease the number of dangerous cyclones in the North Atlantic. However, this would increase droughts in parts of India and the sub-Saharan Africa.
The issue of geoengineering has been brought up into discussions for a while. The main problem is that if used, it could spark serious conflicts between the tropical and the temperate countries. This same study states that if we sprayed aerosol into the Southern hemisphere, it would only create more storms in the North Atlantic. This is not right, especially given the huge damages this year’s tropical storms have inflicted on certain areas.
So, while some experts believe that injecting aerosols might not be the best idea to fight climate change, Harvard scientists are preparing to experiment with it. Only time will tell us what will happen.
