Question

Sulfate aerosols are produced mostly from sulfur dioxide which arises from fossil fuel combustion. Because of their impact on air quality, including its role in acid deposition, efforts to reduce emissions, for example by using scrubbers at coal fired power plants, have succeeded in lowering emissions. Use the Infographic to determine what effect these reductions in emissions would have on climate?

a. Sulfate aerosols are negative forcers and thus have a cooling effect.
b. They can scatter incoming light and increase cloud formation and reflectivity.
c. A reduction in emissions would thus have a warming effect on global climate.
d. Sulfate aerosols are also positive forcers and thus have a warning effect.
e. Only A, B, and C are correct.

Answer 1

e. Only A, B and C are correct.

Step-by-step explanation:

Sulphate Aerosols are produced by chemical reaction in the atmosphere where sulphate solid particles are reacted with some sulphuric acid to form a chemical reaction. This is important for cloud processes and the climate because they act like sea salt. Sulphate aerosol cools the climate and they are negative forces that create a cooling effect.
