Do you know Sunspots and Stratospheric Sulphur aerosols?


Approximately every 11 years sunspots occur. Sunspots are used as a measure of solar activity. What actually a sunspot is, it is the dark region formed on the surface of the sun due to the magnetic field lines emerging through the photosphere preventing heat transfer by convection.

So, why sunspots or Solar activity matters?

The solar activity itself has been linked to satellite failures, electrical power outages, and variations in Earths climate. The impact of solar activity on Earth and our technology has created a need for a better understanding of, and the ability to predict solar activity.

Stratospheric Sulphur Aerosols

When Strong Volcanoes erupt, a cooling effect occurs sometimes for years together. This is because Stratospheric Sulphur Aerosols are formed due to the photochemical decomposition of sulphur-containing gases. These aerosols are sulphur-rich particles which exist in Earth’s stratospheric layer called Junge layer.
Creating stratospheric sulphur aerosols deliberately is a proposed geoengineering technique which offers a possible solution to some of the problems caused by global warming. However, this will not be without side effects and it has been suggested that the cure may be worse than the disease.
