name two prons and two cons of using sulfur dioxide as a tool of geoengineering.

Expert Solution

Answer:

Geoengineering is a term in which certain manual techniques are used in order to reduce the environmental/climatological effects on earth.

Sulphur dioxide is colourless toxic gas. It is naturally emitted in atmosphere due to volcanic activity and dead-decaying organic matter. Several anthropogenic activities such as industries, fossil fuel burning are responsible for leading sulphur emissions in atmosphere.

Follwing pros and cons of sulphur dioxide use in geoengineering are explained below:

Pros:

1. Sulphur dioxide can help in reducing the rising temperatures. In the atmosphere this sulphur compounds reflects the sunlight in space thus reducing the warming effect on earth's surface.

2. This technique is low cost as compared to other techniques as it does not require advanced operating machines. It can be processed by using aircraft or ballons.

Cons:

1. High sulphur rich aerosols may lead to acid rain which is another byproduct leading to harmful environmental effects.

2. Sulphur dioxide moves with winds in the atmosphere which may affect the weather and rainfall pattern
